Abstract Summary PDF: Objectives
Sedentary behavior has emerged as a health risk factor distinct from insufficient physical activity. This study examined the association between sedentary time and high-sensitivity C-reactive protein (hs-CRP), a marker of systemic inflammation, among Korean older adults.
Methods
Data were obtained from the 2022 Korea National Health and Nutrition Examination Survey. Among 1667 participants aged 65 years or older with available hs-CRP measurements, 496 with leukocyte counts ≥10 000 cells/mm3 or hs-CRP levels ≥10.0 mg/L were excluded, yielding a final sample of 1171 participants. hs-CRP levels ≥1.0 mg/L were classified as abnormal. Differences in the prevalence of abnormal hs-CRP were assessed using the chi-square test, and multivariable logistic regression analysis was performed to evaluate the association between sedentary time and abnormal hs-CRP after adjustment for covariates.
Results
The prevalence of abnormal hs-CRP was higher among participants who did not engage in regular walking (prevalence ratio [PR], 1.24; 95% confidence interval [CI], 1.05 to 1.46) and those with adverse cardiometabolic profiles, including elevated blood pressure, dyslipidemia, and abdominal obesity. It was also higher among participants with sedentary time ≥10 hr/day (PR, 1.20; 95% CI, 1.02 to 1.41). In multivariable logistic regression analysis, prolonged sedentary time remained associated with abnormal hs-CRP levels after adjustment for covariates (odds ratio, 1.31; 95% CI, 1.01 to 1.71).
Conclusions
Prolonged sedentary time was independently associated with elevated hs-CRP levels among Korean adults aged 65 years or older. Accordingly, sedentary behavior reduction may be a useful target for chronic disease prevention strategies in older populations.; Summary

Korean summary
2022년 국민건강영양조사 자료를 분석한 결과, 65세 이상 한국 노인에서 하루 10시간 이상의 장시간 좌식행동은 높은 hs-CRP 수준과 독립적으로 관련되었다. 본 연구는 노인의 만성질환 예방과 건강한 노화를 위해 신체활동 증진뿐만 아니라 장시간 좌식행동을 줄이는 전략도 중요할 수 있음을 시사한다.

Key Message
Among Korean adults aged 65 years or older, sedentary time of ≥10 hr/day was independently associated with elevated high-sensitivity C-reactive protein (hs-CRP) levels. These findings suggest that reducing prolonged sedentary time, alongside promoting physical activity, may be an important behavioral target for chronic disease prevention and healthy aging.

Abstract Summary PDF: Objectives
To identify behavioral segments of integrative care use among older adults with knee osteoarthritis in a rural district in Northern Thailand and to compare these segments according to PRECEDE-related factors and baseline characteristics.
Methods
This analytical cross-sectional study included 302 community-dwelling older adults with primary knee osteoarthritis in Thoen District, Lampang Province, Northern Thailand. Data were collected through face-to-face interviews using a structured questionnaire that assessed demographic and health characteristics, PRECEDE-related factors, and behaviors across 3 care domains: professional medical care, traditional medicine, and community-based medicine. Standardized behavioral domain scores were analyzed using hierarchical cluster analysis, followed by k-means clustering. Differences among segments were examined using chi-square tests, one-way analysis of variance, or Kruskal-Wallis tests, as appropriate.
Results
Three behavioral segments were identified: high engagement (20.9%), intermediate engagement (48.0%), and low engagement (31.1%). The 3 behavioral domains differed significantly across segments (all p<0.001; η²=0.400–0.535). Baseline demographic and health characteristics did not differ significantly among segments. In contrast, significant differences among segments were observed for the total enabling score, access, decision-making, total reinforcing score, social support, and attitude, whereas perceived information showed no significant difference.
Conclusions
Older adults with knee osteoarthritis were not behaviorally homogeneous in their use of professional, traditional, and community-based care. Segment differences were more pronounced for enabling and reinforcing conditions than for perceived information alone. These findings support segment-informed health promotion strategies in primary care and community settings.; Summary

Key Message
This study found three distinct patterns of care use among older adults with knee osteoarthritis in rural Northern Thailand: high, intermediate, and low engagement in professional, traditional, and community-based care. Differences between the groups were more apparent in access, decision-making, and social support than in perceived information. These findings highlight the potential value of tailoring primary care and community-based support to the needs of each group.

Abstract Summary PDF Supplementary Material: Objectives
This study aimed to describe the distribution of fall-related injury burden across healthcare stages and age groups in Korea, with particular emphasis on differences between young-old adults (aged 65–74 years) and old-old adults (aged ≥75 years).
Methods
Using the 14th Korea National Injury Statistics Report (2022), we analyzed data on fall-related injuries from 5 national sources: the 119 Emergency Medical Services Registry, the National Emergency Department Information System (NEDIS), the Korea National Hospital Discharge In-depth Injury Survey, the Severe Trauma Survey, and cause-of-death statistics. Five age groups (0–6, 7–18, 19–64, 65–74, and ≥75 years) were defined according to the original classifications used in the data sources. Age-specific crude rates were calculated using mid-year population denominators from Statistics Korea.
Results
Emergency department (ED) visit rates were highest among children aged 0–6 years (2312/100 000) and adults aged ≥75 years (2121/100 000). Despite comparable ED visit rates, the within-NEDIS ED admission rate increased from 2.6% among children aged 0–6 years to 42.9% among adults aged ≥75 years. The hospitalization rate among adults aged ≥75 years (4852/100 000) was 2.6 times higher than that among adults aged 65–74 years (1832/100 000). Among adults aged ≥75 years, the mortality rate was 32.5/100 000, and this age group accounted for 45.4% of all fall-related deaths.
Conclusions
Fall-related injury burden among adults aged ≥75 years was disproportionately concentrated at the hospitalization and mortality stages. These findings suggest that fall prevention strategies for aging populations should consider the downstream burden beyond ED visits.; Summary

Korean summary
본 연구는 2022년 국가손상종합통계를 활용하여 한국 노인의 낙상 관련 손상 부담을 응급실 방문·입원·사망 등 의료단계별로 분석하였다. 75세 이상 초고령 노인에서 부담이 입원과 사망 단계에 불균형적으로 집중되었으며, 응급실 방문률이 유사한 연령대라도 입원 전환율과 사망률은 크게 높았다. 따라서 노인 낙상 예방 전략은 응급실 방문을 넘어 입원·사망 등 후속 단계의 부담까지 함께 고려할 필요가 있다.

Key Message
Using 5 national data sources for 2022, this study shows that the burden of fall-related injuries in older Korean adults is concentrated at the hospitalization and mortality stages rather than at the emergency department (ED) visit stage. Although adults aged ≥75 years and young children had comparable ED visit rates, the oldest adults had far higher admission, hospitalization, and mortality rates, with a steep increase after age 75. Fall-prevention strategies for aging populations should therefore look beyond ED visits and address the downstream inpatient and mortality burden.

Abstract Summary PDF Supplementary Material: Objectives
Thailand is rapidly transitioning to an aged society. Lower limb muscle weakness among older adults is associated with increased fall risk, loss of independence, and reduced quality of life (QoL). Although exercise can improve strength and mobility, many community-dwelling older adults face barriers to participation. We evaluated the effectiveness of an innovative leg support ring for lower limb muscle rehabilitation among older adults in Eastern Thailand.
Methods
This randomized controlled trial, repeated-measures study included 64 adults aged 60 years or older with lower limb muscle weakness and activities of daily living (ADL) scores of 9–11. The intervention group (n=32) used the leg support ring for 12 weeks (3–5 day/wk), while the control group (n=32) received standard care and continued usual physical exercise. Leg motor power, range of motion (ROM), ADL, and QoL were assessed at baseline, immediately post-intervention, and at the 3-month follow-up. Data were analyzed using repeated-measures analysis of variance.
Results
Compared with control participants, the intervention group showed significantly greater improvements in motor power of the quadriceps, hamstrings, hip flexors, ankle dorsiflexors, and ankle plantar flexors (p<0.001) and ROM for hip flexion, hip extension, knee flexion, and ankle plantar flexion (p<0.05). ADL and QoL also demonstrated significantly greater improvements (p<0.001). These improvements were sustained or further increased at the 3-month follow-up.
Conclusions
The leg support ring program was associated with improvements in lower limb strength, mobility, functional independence, and QoL among older adults. Its simplicity and accessibility may support integration into community-based health promotion programs for active aging.; Summary

Key Message
This randomized controlled trial evaluated an innovative leg support ring for lower limb rehabilitation among 64 community-dwelling older adults in Eastern Thailand. Over 12 weeks, the intervention group showed significantly greater improvements in motor power, range of motion, activities of daily living, and quality of life compared with the control group, with benefits sustained at 3-month follow-up. Findings support the leg support ring as a simple, low-cost, community-based rehabilitation tool for active aging.

Abstract Summary PDF: Objectives
This study aimed to investigate the association between obesity and falls among community-dwelling older adults in Korea and to assess whether body mass index (BMI) or waist circumference (WC) more accurately predicts fall risk.
Methods
This study included 4378 community-dwelling older adults aged ≥65 years from the seventh Korea National Health and Nutrition Examination Survey (2016–2018). Complex-sample logistic regression analyses were conducted to examine the associations between general and central obesity and falls, stratified by sex and age group. Predictive accuracy was evaluated using Harrell’s C-index, and differences between WC and BMI were assessed using the ΔC-index and the DeLong test.
Results
BMI-defined general obesity was not significantly associated with falls. In contrast, WC-defined central obesity was significantly associated with falls among older adults overall (adjusted odds ratio, 1.82; 95% confidence interval, 1.20 to 2.76). In sex-stratified analyses, central obesity remained significantly associated with falls in both males and females. Age-stratified analyses showed a significant association between central obesity and falls among adults aged 65–74 years, but not among those aged ≥75 years. WC demonstrated a modest but statistically significant improvement in predictive ability compared with BMI (ΔC-index=0.047, p=0.044), although subgroup differences were not statistically significant.
Conclusions
Central obesity, but not general obesity defined by BMI, was significantly associated with falls among community-dwelling older Korean adults. WC showed slightly better predictive performance than BMI. These findings suggest that WC may be a more appropriate indicator than BMI for identifying older adults at increased risk of falls.; Summary

Korean summary
본 연구는 지역사회 거주 노인을 대상으로 비만과 낙상 간의 관련성을 분석하고, 체질량지수(BMI)와 허리둘레(WC)의 낙상 예측력을 비교하였다. 분석 결과, BMI 기반 일반 비만은 낙상과 유의한 관련이 없었으나, WC 기반 복부비만은 낙상 위험 증가와 유의하게 관련되었으며, 허리둘레가 BMI보다 낙상 예측에 더 우수한 지표로 나타났다. 따라서 노인 낙상 위험 선별 시 BMI보다 허리둘레를 우선적으로 고려할 필요가 있다.

Key Message
Central obesity defined by waist circumference was significantly associated with falls among community-dwelling older adults in Korea, whereas BMI-defined general obesity was not. Waist circumference also demonstrated slightly better predictive performance for falls than BMI. These findings suggest that waist circumference may be a more appropriate anthropometric indicator for identifying older adults at increased risk of falls.

Income-related Inequalities in Cancer Screening Among Korean Adults Aged 40 and Above: A Cross-sectional Analysis of the Age-varying Mediation of Health Literacy: Hyejin Hong, Hyun-Jin Goo, Hyebin Choi, Sin Kam, Jong-Yeon Kim; J Prev Med Public Health. 2026;59(2):184-193.

Abstract Summary PDF Supplementary Material: Objectives
This study investigated how the mediating effect of health literacy (HL) on the association between income and cancer screening participation varies by age among Korean adults aged 40 years and older, with the aim of identifying the optimal timing for HL interventions.
Methods
Data from 4171 adults aged ≥40 years in the 2023 Korea National Health and Nutrition Examination Survey were analyzed using moderated mediation analysis implemented with the lavaan.survey package, accounting for the complex sampling design. The Johnson–Neyman technique was used to identify age thresholds at which the mediation effect became statistically significant, and the number needed to benefit (NNB) was calculated to estimate the potential efficiency of interventions targeting this pathway.
Results
Each 1-quintile increase in income was associated with a 16.0% higher likelihood of undergoing cancer screening (odds ratio=1.16, p<0.001). The mediating effect of HL increased significantly with age (index of moderated mediation=0.000438, p=0.048). Mediation became statistically significant from age 54.2 years (Johnson–Neyman threshold), with the proportion of the total effect mediated rising from 0.1% among adults aged 40–49 years to 8.1% among those aged ≥70 years. The NNB for this pathway indicated substantial intervention efficiency in older adults (NNB=372 for ages ≥70), whereas the mediation effect was not statistically significant in the 50–59 age group.
Conclusions
HL significantly mediated the relationship between income and cancer screening participation from the mid-50s onward, with progressively greater contributions at older ages. These findings support age-differentiated strategies, including structural accessibility improvements for adults in their 40s and early 50s and integrated income–HL interventions for individuals aged ≥55 years. Experimental studies are warranted to confirm these associations.; Summary

Korean summary
40세 이상 한국 성인에서 소득과 암검진 참여 간 건강문해력의 매개효과는 54.2세부터 유의해지기 시작하여 연령 증가에 따라 점진적으로 강화되었다. 70세 이상에서 매개 비율은 8.1%, 중재효율(NNB=372)이 가장 높았다. 이는 55세 이상에서 소득 지원과 건강문해력 향상을 결합한 연령별 맞춤형 중재가 필요함을 시사한다.

Key Message
Health literacy mediation of the income–cancer screening relationship became statistically significant from age 54.2 years and strengthened progressively with age among Korean adults aged ≥40 years. Among adults aged ≥70 years, health literacy accounted for 8.1% of the total income effect, with the highest intervention efficiency (NNB=372). These findings suggest that integrated income support and health literacy interventions are warranted for adults aged ≥55 years.

Abstract Summary PDF Supplementary Material: Objectives
Patient blood management (PBM) is increasingly recognized as an essential strategy in obstetric care for reducing transfusion-related risks and improving maternal safety. Jehovah’s Witness (JW) women, who categorically refuse blood transfusion, represent a unique clinical population in which to evaluate the effectiveness of PBM. This study aimed to assess obstetric outcomes of JW women compared with non-JW women at a PBM-based center in Korea.
Methods
We retrospectively reviewed delivery outcomes and PBM practices among JW women (n=205) with singleton pregnancies and non-JW women (n=601) who were matched at a 1:3 ratio using propensity scores at Soonchunhyang University Seoul Hospital between 2018 and 2023. The primary outcomes included obstetric morbidities, with particular attention to complications related to postpartum hemorrhage and the interventions used for its management.
Results
JW women were more likely to receive intravenous iron administration (7.3 vs. 2.8%, p=0.008) and had higher hemoglobin (Hb) levels during the first trimester (12.6±1.1 vs. 11.8±3.4 g/dL, p=0.012) than non-JW women. Blood loss during cesarean section and the incidence of severe postpartum anemia (Hb <7 g/dL) were lower among JW women; however, these differences did not reach statistical significance. In the hemorrhage-related high-risk subgroup, JW women were managed according to PBM protocols without transfusion, and their obstetric outcomes were comparable to those observed in non-JW women.
Conclusions
This study identified no significant differences in hemorrhage-related obstetric outcomes between JW and non-JW women at a PBM-based center. The systematic application of PBM enables safe delivery in transfusion-restricted settings and may reduce reliance on blood transfusion while maintaining maternal safety.; Summary

Korean summary
수혈을 거부하는 여호와의 증인 산모에게 환자혈액관리(PBM) 프로토콜을 적용한 결과, 일반 산모와 비교하여 산후출혈 및 중증 빈혈 등 주요 산과적 합병증에서 유의한 차이는 관찰되지 않았으며, 이는 선제적인 철분 관리의 기여로 해석된다. 비록 대량 출혈 시에는 적용에 한계가 있으나, 이는 PBM이 종교적 특수 상황을 넘어 향후 혈액 수급 위기에 대응할 수 있는 보편적이고 안전한 산과적 대안이 될 수 있음을 시사한다.

Key Message
Implementation of patient blood management (PBM) in Jehovah’s Witness women who refuse transfusion resulted in obstetric outcomes comparable to those of non-JW women, with no significant differences in postpartum hemorrhage or severe anemia. These outcomes were associated with proactive anemia management, including intravenous iron therapy. Although its applicability may be limited in cases of massive hemorrhage, PBM represents a safe and potentially generalizable obstetric strategy to mitigate future blood supply constraints.

Abstract Summary PDF Supplementary Material: Objectives
The objective of this study was to develop machine learning models to predict health insurance claim costs among older adults in Indonesia.
Methods
This study utilized secondary data from the Indonesian National Health Insurance program (Jaminan Kesehatan Nasional [JKN]) spanning 2017 to 2023. Three modeling techniques—linear regression, random forest, and XGBoost—were employed to predict individual claim costs. Model performance was assessed using the root mean square error (RMSE), coefficient of determination (R²), and mean absolute error (MAE). Additionally, variable importance analysis was conducted to identify key predictors.
Results
XGBoost with 500 boosting rounds yielded the best performance, with an RMSE of 11 360 283, an R² of 0.81, and an MAE of 4 485 917, outperforming both linear regression (RMSE, 13 710 035; R²=0.72) and random forest (RMSE, 12 434 238; R²=0.78). Notably, outpatient care was identified as the most consistent predictor across all models. Other significant predictors included length of stay (LOS), diagnosis type (International Classification of Diseases, 10th revision chapter), facility type, facility classification, and severity of illness, particularly for moderate cases. Although LOS and diagnosis type were important predictors, these findings should be interpreted in the context of Indonesia’s fixed Indonesian Case-Based Groups payment system.
Conclusions
XGBoost provides reliable predictions of claim costs among older adults, capturing clinical, utilization, and structural drivers. These findings can inform targeted interventions, improve chronic disease management, optimize the referral system, and support integration of predictive tools into JKN to enhance responsiveness and promote sustainable, equitable financing.; Summary

Key Message
Machine learning models, particularly XGBoost, demonstrated superior performance in predicting healthcare costs among older adults in Indonesia. Nonlinear relationships between outpatient visits, severity, and diagnoses highlight the limitations of conventional linear approaches. These findings support the integration of advanced predictive models into national health insurance systems to improve cost management and resource allocation.

Abstract Summary PDF: Objectives
Patients undergoing hemodialysis encounter a wide range of complex challenges, underscoring the essential role of self-care in disease management. The present study aimed to examine the effectiveness of an educational intervention grounded in Orem’s self-care model for enhancing treatment adherence, self-care behaviors, and quality of life among hemodialysis patients in southern Iran.
Methods
This single-blind randomized controlled trial included 120 hemodialysis patients who met the predetermined eligibility criteria. Data were collected between April 2023 and August 2023 at 2 university-affiliated teaching hospitals located in southern Iran. After providing informed consent, participants were randomly allocated to either the intervention group (n=60) or the control group (n=60) through a simple randomization procedure. Three psychometrically robust instruments were used to collect data: the End-Stage Renal Disease Adherence Questionnaire, the Kidney Disease Quality of Life Short Form, and the Self-Management Behavior Scale. Statistical analyses were performed using SPSS version 23, and p-values<0.05 were considered statistically significant.
Results
At baseline, no statistically significant differences were observed between the intervention and control groups in the mean scores of the measured variables. However, immediately following the intervention and at the 3-month follow-up, the intervention group demonstrated statistically significant improvements across all 3 variables.
Conclusions
The findings underscore the effectiveness of an educational program based on Orem’s self-care model in significantly improving self-care behaviors, treatment adherence, and quality of life among hemodialysis patients.; Summary

Key Message
Patients undergoing hemodialysis encounter a wide range of complex challenges, underscoring the essential role of self-care in disease management. The findings underscore the effectiveness of an educational program based on Orem’s self-care model in significantly improving self-care behaviors, treatment adherence, and quality of life among hemodialysis patients. The results of this trial carry implications for clinical practice and health policy. It is recommended that contemporary educational methodologies—particularly those grounded in well-established nursing theories such as Orem’s model—be systematically integrated into nursing curricula. Additionally, structured training workshops emphasizing the clinical utility and outcomes of Orem-based self-care education should be incorporated into hospital-based educational programs.

Abstract Summary PDF: Objectives
Health-promoting behaviors are essential for maintaining independence and enhancing quality of life in aging populations. This study aimed to investigate the relationship between social support and health-promoting behaviors among older adults in Fasa, Iran in 2020.
Methods
A cross-sectional study was conducted involving 300 older adults attending a specialized outpatient clinic in Fasa, Iran. Data were collected using a demographic questionnaire, the Walker Health-Promoting Lifestyle Profile, and the Canty Perceived Social Support Scale, administered either through self-report or structured interviews. Statistical analyses were performed using SPSS version 25 and included descriptive statistics, analysis of variance, the chi-square test, and multiple linear regression analyses.
Results
The mean age of participants was 68.9±7.8 years. Most participants were women (56.6%), married (81.7%), and had less than a high school education (41.3%). The mean scores for health-promoting behaviors and perceived social support were 124.2±31.3 and 24.4±9.4, respectively. A statistically significant positive association was observed between perceived social support and health-promoting behaviors (r=0.10, p=0.04). Social support, gender, and education level were identified as significant predictors of health-promoting behaviors, collectively explaining 34% of the variance.
Conclusions
These findings emphasize the pivotal role of social support in promoting health-related behaviors among older adults. Interventions that strengthen social support networks, foster enabling environments, and address gender and educational disparities are recommended to improve health outcomes and quality of life in aging populations. Policymakers and healthcare planners should incorporate these determinants into the design of targeted, evidence-based interventions for older adults.; Summary

Key Message
This study highlights that perceived social support is significantly associated with health-promoting behaviors among older adults in Fasa, Iran. Higher levels of social support, along with demographic factors such as gender and education, significantly predict engagement in healthier lifestyle behaviors. These findings underscore the importance of strengthening social support networks and developing targeted interventions to improve health behaviors and enhance quality of life in aging populations

Abstract Summary PDF Supplementary Material: Objectives
Korea is one of the fastest-aging societies, and a large proportion of its older population lives alone. This study examined the impact of family interaction frequency on the association between living alone and depressive symptoms among older adults aged ≥80 years using nationally representative survey data.
Methods
Among the 229 099 participants of the 2019 Korea Community Health Survey, 15 672 participants aged ≥80 years who either lived with close family or lived alone were included in the analysis. Participants living alone were classified according to the frequency of family interaction, ranging from less than once a month to more than once a week. The outcome variable was moderate to severe depressive symptoms, defined as a Patient Health Questionnaire-9 score of ≥10.
Results
The prevalence of depressive symptoms was higher among older adults living alone (9.4–14.1%, depending on the frequency of family interaction) than among those living with close family (6.5%). Older adults living alone who interacted with family less than once a month were more likely to report depressive symptoms compared with those living with close family (adjusted odds ratio [aOR], 1.71; 95% confidence interval [CI], 1.36 to 2.15). Weekly family interaction mitigated the impact of living alone on the prevalence of depressive symptoms (aOR 1.10; 95% CI, 0.84 to 1.42). The influence of family interaction on the association between living alone and depressive symptoms remained consistent across subgroups of men, women, and those with difficulty in daily activities.
Conclusions
Encouraging regular interaction among family members could serve as an effective strategy to protect the mental health of older adults.; Summary

Methods
This nationwide study involved 1086 community-dwelling older adults aged 55 years and above. Poor appetite was defined using a self-reported question, while cognitive function was assessed with the Montreal Cognitive Assessment. Sarcopenia was identified based on handgrip strength, 6-meter gait speed, and muscle mass, in accordance with the Asian Working Group for Sarcopenia 2019 criteria. Associations between poor appetite, sarcopenia, and cognitive function were analyzed using both univariate and multivariate analyses.
Results
Multivariate analysis revealed that handgrip strength (β=0.067, p=0.012) and gait speed (β=1.080, p=0.017) were significantly associated with cognitive function after adjusting for confounders such as age, ethnicity, marital status, education, and alcohol and smoking consumption. However, no significant association was observed between poor appetite and cognitive function, nor was any moderation effect found between poor appetite and sarcopenia-related traits on cognitive function.
Conclusions
Our study confirms that low muscle strength and reduced physical performance are significantly associated with an increased risk of cognitive impairment among community-dwelling older adults. These findings underscore the critical importance of muscle strength and physical performance in preserving cognitive function—a decline that is not inevitable with age. Routine screening and early detection of muscle health and cognitive function are essential, and should be followed by intervention strategies targeting muscle health to mitigate cognitive decline in aging populations.; Summary

Key Message
Lower muscle strength and slower gait speed were independently associated with poorer cognitive function in Malaysian older adults, while poor appetite showed no direct or moderating effect on cognition. These findings underscore the importance of routine screening and early interventions targeting muscle health to help prevent cognitive decline in aging populations.

Objectives
Digital transformation in hospital pharmacies is a strategic priority to improve medication safety, optimize inventory management, and streamline dispensing. Although healthcare digitalization has been widely studied, evidence of its impact on key performance indicators within hospital pharmacy operations remains limited. This review consolidates available evidence on how digital technologies affect hospital pharmacy performance, focusing on dispensing time, medication safety, and inventory practices.
Methods
A systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. Web of Science, PubMed, and Scopus were searched for English-language studies (2014–2024) conducted in general, academic, or tertiary hospitals. Eligible interventions included automation technologies (e.g., automated dispensing cabinets, robotic dispensing), digital systems (e.g., computerized physician order entry, electronic prescribing), or hybrid platforms. Outcomes included measures of dispensing efficiency, medication safety, and inventory management. Two reviewers independently screened studies and extracted data.
Results
Of 319 records, 9 studies met the inclusion criteria, spanning Saudi Arabia, the United States, Denmark, Iran, Jordan, Australia, and France. Most reported improvements in dispensing efficiency, safety (through lower error rates), and inventory control. Secondary gains included streamlined workflows and higher staff satisfaction. Challenges included resource-intensive implementation, workflow disruption, technological downtime, interoperability issues, and reliance on user compliance. Operational gains did not always yield measurable clinical benefits such as reduced morbidity or length of stay.
Conclusions
Digital technologies can improve efficiency, safety, and inventory control in hospital pharmacies; however, their success depends on institutional readiness, infrastructure, and human factors. Robust studies are needed to evaluate long-term impacts, cost-effectiveness, and implementation strategies.

Summary

Key Message
Digital technologies such as automated dispensing cabinets, electronic prescribing, barcode medication administration, and robotic systems can substantially improve dispensing efficiency, medication safety, and inventory control in hospital pharmacies. This systematic review shows consistent reductions in dispensing time, medication errors, stock-outs, and expired drugs across diverse healthcare settings. However, the benefits of digitalization depend on institutional readiness, adequate infrastructure, staff training, and sustained user compliance, highlighting the need for context-sensitive implementation strategies.

Abstract Summary PDF Supplementary Material: Objectives
This study was performed to quantify the impact of coronavirus disease 2019 (COVID-19) on hospital profitability in Korea by analyzing changes in the medical revenue-to-profit ratio (MRPR) and net income before reserve fund allocation (NIBR) before and after the pandemic onset. Additionally, it examined how financial outcomes varied by hospital ownership, geographic location, and type (secondary or tertiary), providing insights into the financial resilience of various hospital types during public health crises.
Methods
We conducted a longitudinal analysis using publicly available financial disclosure data from 243 general hospitals in Korea (2016–2022). We then performed a quadrant analysis to classify hospitals based on changes in MRPR and NIBR, identifying patterns of financial impact. For inferential analysis, we employed linear mixed-effects models incorporating a difference-in-differences framework, enabling estimation of both time-varying and hospital-specific effects.
Results
Following the onset of COVID-19, MRPR declined significantly, reaching −10.62% in 2020. NIBR initially dropped but later increased, reaching 21.09 billion Korean won per 100 beds in 2022. Quadrant analysis revealed substantial heterogeneity in financial responses, with national/public hospitals experiencing the most severe MRPR decline, whereas educational foundation and medical corporation hospitals displayed stronger financial recovery. Regression results confirmed significant interactions between outcomes after COVID-19 onset and hospital ownership type, indicating differential financial impacts across hospital categories.
Conclusions
The findings highlight the uneven financial effects of COVID-19 on Korean hospitals, emphasizing the importance of targeted government financial support. Policy measures should prioritize structural financial reforms to ensure hospital sustainability beyond short-term crisis management.; Summary

Abstract Summary PDF

Objectives
Family caregivers play a crucial role in the care of children with human immunodeficiency virus (HIV); however, they frequently face limitations in knowledge, attitudes, and skills. Mobile application (app)-based training may offer an effective solution to enhance caregiver competence. This study aimed to assess the effectiveness of mobile app-based care management training in improving the knowledge, attitudes, and skills of family caregivers caring for children with HIV.
Methods
A quasi-experimental design, including pretest, posttest, and follow-up assessments, was conducted at a national referral hospital for infectious diseases in Jakarta, Indonesia. The study involved 44 respondents, divided equally into intervention and control groups (22 per group). The intervention group received mobile app-based training, while the control group received conventional caregiver education. Questionnaires assessing caregivers’ knowledge, attitudes, and skills in managing children with HIV were utilized. Data were analyzed using independent sample t-tests and repeated measures analysis of variance (ANOVA).
Results
Repeated measures ANOVA revealed that the intervention group experienced significant improvements in knowledge, attitudes, and skills from pretest to posttest, which were maintained at the 1-month follow-up (p<0.001). In contrast, the control group did not exhibit significant changes in any of these variables (knowledge, attitudes, and skills) throughout the study period.
Conclusions
Mobile app-based care management training significantly enhances caregiving competencies among family caregivers of children with HIV. These findings underscore the potential of digital technology as an innovative and sustainable approach for caregiver training in various healthcare settings, supporting the long-term effectiveness of educational interventions.

Summary

Key Message
This quasi-experimental study evaluated the effectiveness of a mobile app-based care management training for family caregivers of children with HIV in Indonesia. The intervention significantly improved caregivers’ knowledge, attitudes, and skills compared to the control group. These findings suggest that digital health tools can empower caregivers, enhance pediatric HIV care, and provide a scalable model for supportive training in resource-limited settings.

Objectives
People-centered care and social protection are critical for improving tuberculosis (TB) treatment outcomes. This study aimed to evaluate whether a vulnerability assessment tool, developed for an enhanced community-based care and management (ECCM) program in 2 Korean cities, could predict and improve final TB treatment outcomes based on patients’ vulnerability levels.
Methods
Treatment outcomes in the ECCM group were compared with those in a control group, stratified by vulnerability level. During stage 1, one city served as the intervention region and the other as the control, with a crossover in stage 2. The vulnerability assessment included all notified patients with TB, and those identified as highly vulnerable in the intervention group received social support following a consultation with a case manager.
Results
The vulnerability assessment tool demonstrated moderate predictive ability for unfavorable outcomes, with an area under the curve of 0.70 (95% confidence interval, 0.63 to 0.77). The patients with high vulnerability who received ECCM treatment demonstrated a 19.8-percentage point (%p) higher treatment success rate than the high vulnerability subcategory of the control group. ECCM also appeared to reduce loss to follow-up and TB-related mortality by 8.4%p and 7.3%p, respectively, although these findings should be interpreted with caution.
Conclusions
The results suggest that providing social support tailored to patient vulnerability at the time of diagnosis could improve TB treatment outcomes.

Summary

Korean summary
결핵 진단 시점의 임상적, 사회적, 그리고 결핵 관련 취약성 평가는 부정적인 치료 결과를 예측하는 데 유의미한 지표가 될 수 있다. 높은 취약성을 지닌 집단에 대해 지역사회 기반의 맞춤형 사례관리를 시행한 결과, 부정적 치료 결과를 일정 수준 감소시킬 수 있었다. 결핵의 사회적 결정요인과 노년 결핵환자 증가라는 역학적 상황은 지역사회 기반의 사회적 지원을 통해 개선 가능할 것이다.

Key Message
Clinical, social, and tuberculosis-related vulnerabilities assessed at the time of TB diagnosis can serve as meaningful predictors of unfavorable treatment outcomes. Community-based, ehnahced case management for highly vulnerable groups has been shown to reduce such negative outcomes to some extent. The social determinants of tuberculosis and the increasing prevalence of TB among the elderly may be addressed through community-based social support.

Abstract Summary PDF

Objectives
This study aimed to explore the role of community-level social welfare expenditures in depressive symptoms among older adults in Korea, with a particular focus on living arrangements.
Methods
Multi-level data—comprising individual-level data from the 2019 Community Health Survey and regional-level data from the Korean Statistical Information Service—were analyzed using multi-level ordered logistic regression. The dependent variable was the severity of depressive symptoms as measured by the Patient Health Questionnaire-9 score, and the primary independent variables were per capita social welfare expenditure, living arrangements, and their cross-level interaction term.
Results
Older adults living alone exhibited more severe depressive symptoms compared to those living with others (odds ratio [OR], 1.22; p=0.006). Higher community social welfare expenditure was significantly associated with reduced depressive symptom severity (OR, 0.73; p=0.019). Moreover, the protective effect of social welfare expenditure was more pronounced among older adults living alone than among those not living alone (OR, 0.92; p=0.046). Social welfare expenditure was highly correlated with social cohesion, which weakened its independent association with depressive symptoms.
Conclusions
This study highlights the potential of community-level social welfare expenditure to mitigate depressive symptoms among older adults, particularly those who live alone. In light of the rising number of older adults living alone, these findings suggest that non-medical interventions, such as enhanced social welfare programs, may help alleviate depression in this vulnerable population. The strong positive correlation between social welfare expenditure and social cohesion also raises further research questions regarding their interrelationship.

Summary

Korean summary
자치단체의 일인당 사회복지 지출이 증가할수록 해당 지역에 거주하는 노인의 우울 증상이 전반적으로 감소하는 결과를 보였고 이러한 연관성은 특히 독거 노인에게서 더 뚜렷하게 나타났다. 이 결과는 노인인구 규모 및 독거 노인 비율의 증가가 초래할 수 있는 노인 정신 건강의 부정적 영향을 비의료적, 사회적 개입을 통해 완화할 수 있음을 시사한다.

Key Message
Higher community-level social welfare expenditure was associated with lower severity of depressive symptoms among older adults, with this association more pronounced among those living alone. Given the rising number of older adults living alone, these findings highlight the potential of non-medical, social interventions to alleviate depression in this vulnerable population.

Abstract Summary PDF

Objectives
This study examined the association between oral health-related quality of life (OHRQoL), as assessed by the Geriatric Oral Health Assessment Index (GOHAI), and cardiovascular disease (CVD) outcomes among Korean older adults.
Methods
Data from 5413 participants in the Korean Longitudinal Study of Aging were analyzed. GOHAI scores were categorized as either “poor” (<40) or “not poor” (≥40). Generalized estimating equation models were used to assess the relationship between GOHAI scores and CVD prevalence, with analyses stratified by sex.
Results
Poor GOHAI score was significantly associated with elevated odds of CVD (odds ratio [OR], 1.13; 95% confidence interval [CI], 1.07 to 1.19; p<0.001). This association was stronger in female (OR, 1.36) compared to male (OR, 1.12). Poor oral health is indicative of systemic inflammation and age-related vulnerabilities, underscoring the utility of the GOHAI as an instrument for early identification of CVD risk.
Conclusions
Poor oral health, as measured by the GOHAI, is associated with an increased risk of CVD among older adults, especially female. These findings support the use of the GOHAI as a cost-effective screening tool for the early assessment of CVD risk. Further research is warranted to explore inflammatory biomarkers and sex-specific mechanisms that could inform targeted interventions.

Summary

Abstract Summary PDF Supplementary Material

Objectives
Adhering to management guidelines, including routine follow-up and education, is crucial for the effective management of chronic diseases such as diabetes. Uncontrolled diabetes is linked to poor sleep quality. We used nationally representative data from community-dwelling Koreans to investigate potential associations between non-adherence to diabetes management and poor sleep quality.
Methods
Of the 228 340 participants in the 2018 Korea Community Health Survey, we analyzed data from 68 246 participants aged 65 years and older. Based on their diabetes status and adherence to diabetes-related tests (glycated hemoglobin, fundus examination, and urine microalbuminuria) and management education, study participants were divided into 3 groups: no diabetes, adherence, and non-adherence. Outcome variables included poor overall sleep quality and sleep disturbances, as measured by the Pittsburgh Sleep Quality Index.
Results
The study included 934 participants in the adherence group (2.0%) and 13 420 in the non-adherence group (20.2%). Participants displaying non-adherence were significantly more likely to report poor overall sleep quality (adjusted odds ratio [aOR], 1.09; 95% confidence interval [CI], 1.04 to 1.13) and to experience sleep fragmentation, nocturia, pain during sleep, and difficulty falling asleep compared to participants without diabetes. Even in the earlier stage of diabetes, non-adherent participants were more likely to report poor sleep quality (aOR, 1.06; 95% CI, 1.00 to 1.18).
Conclusions
Patients with diabetes who do not follow management guidelines are more likely to experience poor sleep quality than those without diabetes. Emphasizing diabetes management and increasing awareness of management strategies may improve sleep quality among patients with this disease.

Summary

Korean summary
혈당조절이 되지 않는 당뇨병이 수면 관련 문제의 발생 위험을 높이는 것은 기존 연구에서 알려져 있었으나, 당뇨관리 여부가 지역사회에 거주하는 당뇨환자들의 수면의 질에 미치는 영향은 충분히 탐구 되지 않았었다. 당뇨 관리 (연 2회 이상 당화혈색소 검사, 매년 당뇨합병증 검사, 당뇨관리교육 이수)에 순응하지 않는 당뇨환자들은 당뇨가 없는 일반인들에 비해 수면 문제를 호소할 가능성이 유의하게 높은 것이 확인되었다. 이는 당뇨 유병기간으로 층화분석하였을때도 일관되게 확인되었다.

Key Message
Uncontrolled diabetes is associated with increased risk of sleep-related problems, but the knowledge on the impact of poor diabetes management on the sleep quality of community dwelling patients with diabetes is limited. Diabetes patients who did not adhere to diabetes management (<2 hemoglobin A1c tests, did not take diabetes complication test, or received diabetes management education) were more significantly more likely to report overall poor sleep quality than those without diabetes. The above association remained significant when the patients were stratified by diabetes duration.

Abstract Summary PDF

Objectives
The International Classification of Functioning, Disability, and Health (ICF) model provides a comprehensive framework for understanding health and quality of life (QoL) in older adults in both rural and urban settings, each presenting unique advantages and challenges. This study aimed to explore the relationship between factors based on the ICF model and QoL among older residents of these areas.
Methods
A cross-sectional study was conducted, involving 286 older adults aged 60 years or older from rural and urban areas of Surakarta, Central Java, Indonesia. The WHOQoL-BREF was utilized to assess QoL. The co-factors included personal factors, impairments, and activity limitations.
Results
Multiple linear regression analysis indicated that cardiovascular endurance was the strongest significant factor associated with QoL in rural areas (B=0.027, standard error [SE]=0.013, p=0.050). In urban areas, gender emerged as the most significant factor influencing QoL (B=-13.447, SE=2.360, p<0.001), followed by hemoglobin level (B=-1.842, SE=0.744, p=0.015), age (B=-0.822, SE=0.217, p<0.001), and cognitive function (B=0.396, SE=0.162, p=0.016).
Conclusions
Efforts to improve QoL for older adults in rural areas should focus on enhance physical performance through exercise. In urban areas, the maintenance of QoL is influenced by personal factors. It is crucial to address physical performance through exercise to enhance QoL in rural settings. Meanwhile, focusing on mental health, financial security, and social connections is recommended to improve QoL for older adults in urban areas.

Summary

Key Message
The ICF model offers a comprehensive framework to assess health and QoL in older adults living in rural and urban areas. Both areas highlight the distinct advantages and challenges unique. Cardiovascular endurance is a vital factor in determining the QoL for older adults in rural areas, while hemoglobin levels, age, and cognition shape the well-being of those in urban environments.

Objectives
In this review, the primary objective was to comprehensively summarize and evaluate the themes and analytical strategies of studies that used data linkage methods to examine the healthcare engagement of individuals with self-harming and suicidal tendencies. Additionally, the review sought to identify gaps in the existing literature and suggest directions for future research in this area.
Methods
This review utilized the PubMed, PsycINFO, and Scopus databases. Employing a scoping review methodology, 27 papers were analyzed.
Results
One particularly common data source is the routine information collected by government agencies. However, some studies supplement this data with newly collected information. Compared to other research methods, data linkage offers the advantage of incorporating participants from diverse backgrounds into the analysis. Most relevant studies using data linkage methods have primarily focused on identifying socio-demographic correlates of self-harm, suicide deaths, and healthcare interactions. Additionally, some studies have used cluster analysis to identify patterns of healthcare utilization within affected populations. Certain papers have employed unique methods to measure self-harm and healthcare interactions, while one study utilized a moderator analytical approach.
Conclusions
Data linkage offers a promising approach for researching the dynamics between self-harm, suicide, and healthcare contact. A notable challenge, however, is the focus of most studies on the associations between socio-demographic factors and the risks of self-harm and suicide.

Summary

Key Message
The scoping review aims to summarize and evaluate the themes and analytical strategies of studies that have used data linkage methods to examine the healthcare engagement of individuals with self-harming and suicidal tendencies. Data linkage offers a promising approach for researching the dynamics between self-harm, suicide, and healthcare contact. However, most studies primarily focus on the associations between socio-demographic factors and the risks of self-harm and suicide. Future research should emphasize the inclusion of additional variables through new data collection, integrating them with existing datasets, or adopting more innovative approaches to analyzing available data.

Abstract Summary PDF

Objectives
This study explored the specific medication-related burdens experienced by older adults with chronic disease and the contributing factors.
Methods
An exploratory mixed-method study was conducted at a teaching hospital in Surakarta City, Central Java, Indonesia. Combining the Indonesian version of the Living with Medicine Questionnaire (LMQ) and semi-structured interviews allowed for a comprehensive understanding of the medication-related burden. Differences in LMQ scores related to patient characteristics were analyzed using the t-test, F-test, or other alternatives. Quantitative and qualitative data triangulation was used to derive trustworthy and dependable results.
Results
The overall LMQ mean score was 90.4 (n=129), indicating a moderate burden. The average LMQ scores varied significantly based on the number of medications, treatment duration, and the presence of cardiovascular disease (CVD), diabetes mellitus (DM) and stroke. The qualitative study found 3 themes in the chronic medication use of older adults: experiences, challenges, and motivation. Despite their limited understanding of a medication’s name and indication, some patients managed their medications based on the physical look and packaging of the medication. The study also found that patient motivation and familial support could effectively counteract the fatigue and dissatisfaction associated with taking medication.
Conclusions
Older adults with chronic diseases faced medication-related burdens associated with the presence of CVD, DM, stroke, a treatment duration >5 years, and the use of >10 medications. Effective communication with healthcare professionals is required to understand patients’ needs and concerns, thereby helping manage the challenges of medication-related burdens.

Summary

Key Message
Older adults with chronic diseases experienced an increasing burden in taking medication with multimorbidity, number of medicines and duration of illness. Motivation and familial support is crucial to minimize these burdens.

Abstract Summary PDF

Objectives
This study aimed to identify factors associated with life satisfaction by developing machine learning (ML) models to predict life satisfaction in older adults living alone.
Methods
Data were extracted from 3112 older adults participating in the 2020 Korea Senior Survey. We employed 5 ML models to classify the life satisfaction of older adults living alone: logistic Lasso regression, decision tree-based classification and regression tree (CART), C5.0, random forest, and extreme gradient boost (XGBoost). The variables used as predictors included demographics, health status, functional abilities, environmental factors, and activity participation. The performance of these ML models was evaluated based on accuracy, precision, recall, F1-score, and area under the curve (AUC). Additionally, we assessed the significance of variable importance as indicated by the final classification models.
Results
Out of the 1411 older adults living alone, 45.3% expressed satisfaction with their lives. The XGBoost model surpassed the performance of other models, achieving an F1-score of 0.72 and an AUC of 0.75. According to the XGBoost model, the five most important variables influencing life satisfaction were overall community satisfaction, self-rated health, opportunities to interact with neighbors, proximity to a child, and satisfaction with residence.
Conclusions
Overall satisfaction with the community environment emerged as the most significant predictor of life satisfaction among older adults living alone. These findings indicate that enhancing the supportiveness of the community environment could improve life satisfaction for this demographic.

Abstract Summary PDF

Population aging is a global health priority due to the dramatic increase in the proportion of older persons worldwide. It is also expected that both global life expectancy and disability-free life expectancy will increase, leading to a significant rise in the proportion of individuals with extreme longevity, such as non-agenarians and centenarians. The inaccuracy of clinical evidence on therapeutic interventions for this demographic could lead to biased decision-making, influenced by age-related beliefs or misperceptions about their therapeutic needs. This represents a potential clinical ageism scenario stemming from gaps in clinical evidence. Such biases can result in 2 significant issues that adversely affect the health status and prognosis of older persons: polypharmacy and therapeutic inertia. To date, documents on polypharmacy in non-agenarians and centenarians account for less than 0.35% of the overall available evidence on polypharmacy. Furthermore, evidence regarding therapeutic inertia is non-existent. The purpose of this letter is to discuss polypharmacy and therapeutic inertia as potential clinical ageism scenarios resulting from the clinical evidence gaps in extreme longevity.

Objectives
Prior research has not yet examined the relationship between post-term birth and neonatal mortality in Japan, along with factors associated with post-term birth. We investigated these associations utilizing nationwide birth data from Japan.
Methods
Birth and mortality data were obtained from the Vital Statistics of Japan for the years 2017 to 2022. The post-term birth rate was calculated by birth characteristics, and the neonatal mortality rates for post-term and term births were computed. Additionally, log-binomial regression analysis was employed to explore the associations between post-term birth and neonatal mortality, as well as between various characteristics and post-term birth. The characteristics considered included infant sex, maternal age group, parity, maternal nationality, maternal marital status, and household occupation.
Results
This study analyzed data from 4 698 905 singleton infants born at 37 weeks of gestational age or later. Regression analysis revealed that post-term birth was positively associated with neonatal mortality. The adjusted risk ratio for neonatal mortality in post-term compared to term births was 8.07 (95% confidence interval, 5.06 to 12.86). Factors positively associated with post-term birth included female infant sex, older maternal age, primiparity, non-Japanese maternal nationality, unmarried status, and various household occupations, including farmer, full-time worker at a smaller company, other type of worker, and unemployed. Younger maternal age was inversely associated with post-term birth.
Conclusions
In Japan, post-term birth represents a risk factor for neonatal mortality. Additionally, socio-demographic characteristics, such as maternal marital status, nationality, and parity were found to be predictors of post-term birth.

Summary

Key Message
This study investigated the relationship between post-term birth and neonatal mortality in Japan, along with factors associated with post-term birth. Regression analysis revealed that post-term birth was significantly and positively associated with neonatal mortality. Additionally, socio-demographic characteristics, such as older maternal age, primiparity, non-Japanese maternal nationality, and unmarried status were found to be predictors of post-term birth.

Abstract Summary PDF Supplementary Material: Objectives
Lack of physical activity has a critical effect on the physical and mental health of adolescents. This study examined the influence of family adversities on the longitudinal changes in physical inactivity among adolescents during the coronavirus disease 2019 (COVID-19) pandemic.
Methods
The study used multi-wave data from the Korean Children and Youth Panel Survey, including 2590 Korean adolescents aged 12-14 years. The longitudinal trajectory of physical inactivity among adolescents and the effects of related factors were estimated using a latent growth modeling method.
Results
Our results revealed a significant increase in physical inactivity among adolescents over time. At the onset of the pandemic, approximately one-seventh of Korean middle schoolers reported a lack of physical activity. However, 3 years later, during the quarantine, nearly one-fifth of these adolescents reported a significant increase in their physical inactivity. Initially, low level parental education was predictive of adolescents’ physical inactivity, but this effect diminished over time, becoming statistically insignificant by the end of the 3-year period. Moreover, the increase in physical inactivity over the 3 years was significantly influenced by parental rejection.
Conclusions
These findings suggest that adolescents who experience parental rejection are more likely to report an increase in sedentary behaviors in contexts such as the COVID-19 pandemic.; Summary

Abstract Summary PDF

Objectives
Mental health issues have become a growing concern worldwide. Research has shown that regular physical activity (PA) can positively affect mental health. This study investigated the associations between PA and mental health problems (MHPs) in middle-aged Indonesians.
Methods
The study utilized data from the 2018 Indonesian Basic Health Research Survey and used a cross-sectional approach. The participants included individuals aged 40-60 years who completed the 20-question Self-Reporting Questionnaire. A logistic regression was performed to analyze a sample of 263 930 data points.
Results
Nearly 10.4% of the participants suffered from mental health issues. Notably, among those who did not engage in moderate and vigorous PA, a sign of MHPs was found in 12.5% of participants. Those who met World Health Organization standards for PA were less likely to experience MHPs (10.1%). This study found a significant association between PA and mental health. After adjusting for smoking, alcohol consumption, non-communicable diseases, and socio-demographic variables like age, sex, education, occupation, marital status, and residence, the connection between PA and mental health became even stronger (adjusted odds ratio, 0.81; 95% confidence interval, 0.78 to 0.85; p<0.001).
Conclusions
Regular PA has been shown to affect mental health positively. Therefore, it is important to improve health education and efforts to raise awareness among middle-aged Indonesians about the importance of PA in maintaining good mental health.

Summary

Key Message
This study revealed a significant association between physical activity (PA) and mental problems (MHPs) among middle-aged Indonesians. Individuals who engaged in moderate to vigorous PA were less likely to experience MHPs compared to those who did not meet recommended PA levels. This association remained strong after adjusting confounding variables such as smoking, alcohol consumption, non-communicable diseases, and socio- demographic factors. Therefore, promoting regular physical activity could be a beneficial strategy for improving mental health status in this population.

Objectives
The aim of this study was to analyze the relationship between objective social isolation (SI) and unmet medical needs (UMN) in adults aged 19 and older.
Methods
A cross-sectional analysis was conducted of 208 619 adults aged 19 and older, excluding missing data, using the 2019 Korea Community Health Survey. To analyze the association between objective SI and UMN, the chi-square test and logistic regression analysis were performed.
Results
The prevalence of UMN was 1.14 times higher (odds ratio [OR], 1.14; 95% confidence interval [CI], 1.06 to 1.23) among those with SI than among those without SI, and the OR for groups with 5 SI types was 2.77 (95% CI, 1.86 to 4.12) compared to those with no SI types. In addition, a stratified analysis by age group showed that the association between SI and UMN existed even in groups under 64 years old. However, among those aged 65 and older, SI was associated with an OR of 1.53 (95% CI, 1.37 to 1.71) for UMN compared to non-SI. As the number of SI types increased, the prevalence of UMN also increased, indicating a strong association between SI and UMN in older adults.
Conclusions
This study found that individuals with SI experienced UMN due to fear and anxiety about interpersonal relationships. Therefore, based on the results of this cross-sectional study, it is necessary to investigate the causal relationship between SI and UMN through future longitudinal data.

Key Message
This study analyzed the association between social isolation and unmet medical needs using the 2019 Korea Community Health Survey. The analysis revealed that individuals experiencing social isolation had a higher rate of unmet medical needs compared to the non-social isolation group. Furthermore, a stronger association was observed as the intensity of social isolation increased. Based on the results of this study, there is a need to establish policy and institutional foundations to support vulnerable groups with unmet medical needs.

Abstract Summary PDF

For nearly four decades, Ugandans have experienced a period marked by hope, conflict, and resilience across various aspects of healthcare reform. The health insurance system in Uganda lacks a legal framework and does not extend benefits to the entire population. In Uganda, community-based health insurance is common among those in the informal sector, while private medical insurance is typically provided to employees by their workplaces and agencies. The National Health Insurance Scheme Bill, introduced in 2019, was passed in 2021. If the President of Uganda gives his assent to the National Health Insurance Bill, it will become a significant policy driving health and universal health coverage. However, this bill is not without its shortcomings. In this perspective, we aim to explore the complex interplay of challenges and opportunities facing Uganda’s health sector.

Summary

Key Message
For the Ugandans, nearly the last four decades have been years of hope, conflict, and resilience in a myriad of contexts for healthcare reform. Health insurance system has no legal framework and provides benefits not to the entire national population. The 2019 National Health Insurance scheme Bill was passed in 2021. If the President of Uganda assents to the National Health Insurance Bill, it will be a compelling policy in health and health for all policies. But this Bill has several drawbacks. In this perspective, we aimed to provide intricacies and mix of challenges and opportunities for the health sector.

Abstract Summary PDF

Objectives
Adolescents who engage in unhealthy behaviors are particularly vulnerable to anxiety. We hypothesized that participation in physical activity could influence the relationship between anxiety and unhealthy behaviors in adolescents. These behaviors include smoking, alcohol consumption, and unsafe sexual activity.
Methods
This study included 50 301 students from the first year of middle school to the third year of high school, all from Korea. The unhealthy adolescent behaviors examined included current alcohol consumption, current smoking, and unsafe sexual behavior. Anxiety levels were assessed using the Generalized Anxiety Disorder-7 questionnaire (GAD-7).
Results
The participants had a mean age of 15.19 years and an average GAD-7 score of 4.23. No significant differences were observed in GAD-7 score among exercising participants when categorized by smoking status (p=0.835) or unsafe sexual behavior (p=0.489). In contrast, participants in the non-exercise group who engaged in these behaviors demonstrated significantly higher GAD-7 scores (p<0.001 and 0.016, respectively). The only significant interaction was found between unsafe sexual behavior and exercise (p=0.009). Based on logistic regression analysis, within the non-exercise group, significant positive associations were observed between current smoking and anxiety (odds ratio [OR], 1.36; 95% confidence interval [CI], 1.18 to 1.57), as well as between unsafe sexual behavior and anxiety (OR, 1.33; 95% CI, 1.02 to 1.73). However, within the exercise group, no significant association was found between anxiety and either smoking or unsafe sexual behavior. Furthermore, no significant interaction was observed between unhealthy behaviors and exercise.
Conclusions
These findings are insufficient to conclude that physical activity influences the relationship between unhealthy behaviors and anxiety.

이 연구는 신체활동이 한국 청소년들사이에서 불안과 불건강행태간의 관계에 어떠한 영향을 미치는지 조사하였다. 이 연구에서 신체활동을 하지 않는 청소년에서만 흡연 및 불안전한 성행위와 같은 불건강행태와 불안 간의 유의미한 연관성을 보였음에도 불구하고, 이러한 불건강행태와 운동 간에는 같은 방향의 유의미한 상호작용이 관찰되지 않았다. 따라서 이 연구는 신체 활동이 청소년들의 불건강행태와 불안간의 관계에 직접 미치는 영향에 대해 명확하게 결론을 내릴 수 없었다.

Key Message
Among Korean adolescents, this study found that significant associations between unhealthy behaviors such as smoking and unsafe sex, and anxiety were only observed in adolescents who did not engage in physical activity. Despite this, no significant interaction was observed between these unhealthy behaviors and exercise. Contrary to popular belief, this study concludes that the evidence is insufficient to definitively say that physical activity influences the relationship between adolescent unhealthy behaviors and anxiety.

Abstract Summary PDF Supplementary Material

Epidemiological models, also known as host-agent-vector-environment models, are utilized in public health to gain insights into disease occurrence and to formulate intervention strategies. In this paper, we propose an epidemiological model that incorporates both conventional measures and tobacco endgame policies. Our model suggests that conventional measures focus on relationships among agent-vector-host-environment components, whereas endgame policies inherently aim to change or eliminate those components at a fundamental level. We also found that the vector (tobacco industry) and environment (physical and social surroundings) components were insufficiently researched or controlled by both conventional measures and tobacco endgame policies. The use of an epidemiological model for tobacco control and the tobacco endgame is recommended to identify areas that require greater effort and to develop effective intervention measures.

이 연구는 기존의 담배규제와 관련된 역학 모형을 확장하여 담배 수요를 줄이기 위한 조치인 MPOWER 정책과 담배 종결전의 주요 정책을 아우르는 개념적 모형을 제시하였다. 각 정책을 개념적 모형 내 배치한 결과, MPOWER 정책은 모형 내 구성요소 간의 연결을 끊는 것을 목표로 하는 반면, 종결전 정책은 모형 내 요소들을 영구적으로 변화시키거나 제거하려는 특성을 가지고 있는 것으로 나타났다. 담배규제정책이 개체, 병원체, 벡터 및 환경 요소에 대한 균형 잡힌 포트폴리오를 갖추고 있는지 평가하기 위해 이 개념적 모형을 활용할 수 있다.

Key Message
We extended the conceptual epidemiological model for tobacco control by incorporating measures to reduce the demand for tobacco (MPOWER measures) and key endgame policies. The model suggests that MPOWER measures focus on disconnecting the relationships between model components, while endgame policies aim to permanently change or eliminate the components themselves. This model can be used to examine whether a country or jurisdiction's tobacco control policy maintains a balanced portfolio across agent, host, vector, and environmental factors.

Abstract Summary PDF

Objectives
The purpose of this study was to assess predictors of health-related quality of life (HRQoL) in elderly Asian American and non-Hispanic White cancer survivors.
Methods
We conducted cross-sectional secondary data analyses using the combined datasets from the Surveillance, Epidemiology, and End Results program and the Medicare Health Outcomes Survey.
Results
Elderly Asian American cancer survivors reported a lower mental HRQoL but a comparable physical HRQoL relative to elderly non-Hispanic White cancer survivors. Stress factors, such as comorbidities, difficulties with activities of daily living, and a history of depressive symptoms, along with coping resources like self-rated health and the ability to take the survey in English, were significantly associated with mental and physical HRQoL. Among elderly Asian American cancer survivors, a significantly lower mental HRQoL was observed among those taking the survey in the Chinese language.
Conclusions
The findings suggest that race exerts a differential impact on HRQoL. Interventions should be designed to address the distinct cultural, linguistic, and systemic needs of elderly Asian American cancer survivors. Such an approach could assist in reducing cancer-related health disparities.

Summary

Key Message
Secondary data analyses of the Surveillance, Epidemiology, and End Results program and the Medicare Health Outcomes Survey combined datasets reveal that elderly Asian American cancer survivors had poorer mental health-related quality of life (HRQoL) compared to their non-Hispanic White counterparts. Elderly Asian American cancer survivors who did not complete the survey in English had significantly worse mental HRQoL than their Asian American counterparts who did. These findings point to the need for increased research to identify and address the distinct cultural, linguistic, and system-related needs of elderly Asian American cancer survivors in order to optimize HRQoL in this population.

Abstract Summary PDF

Cancer management has become a major policy goal for the government of the Korea. As such, the government introduced the National Cancer Control Plan (NCCP) to reduce the individual and social burdens caused by cancer and to promote national health. During the past 25 years, 3 phases of the NCCP have been completed. During this time, the NCCP has changed significantly in all aspects of cancer control from prevention to survival. The targets for cancer control are increasing, and although some blind spots remain, new demands are emerging. The government initiated the fourth NCCP in March 2021, with the vision of “A Healthy Country with No Concerns about Cancer Anywhere at Any Time,” which aims to build and disseminate high-quality cancer data, reduce preventable cancer cases, and reduce gaps in cancer control. Its main strategies include (1) activation of cancer big data, (2) advancement of cancer prevention and screening, (3) improvement in cancer treatment and response, and (4) establishment of a foundation for balanced cancer control. The fourth NCCP has many positive expectations, similar to the last 3 plans; however, cross-domain support and participation are required to achieve positive results in cancer control. Notably, cancer remains the leading cause of death despite decades of management efforts and should continue to be managed carefully from a national perspective.

Abstract PDF

Objectives
This study aimed to identify risk factors associated with coronavirus disease 2019 (COVID-19) mortality in pre-elderly and elderly individuals in Jakarta, Indonesia.
Methods
We employed a case-control study design, utilizing secondary data from the Epidemiology Surveillance, Immunization Prevention, and Disease Control Sections of the DKI Jakarta Provincial Health Office, collected from December 2020 to January 2021. The study included 188 cases and an equal number of controls. Cases were COVID-19 patients confirmed to have died, as reported by hospitals and communities and subsequently verified by healthcare workers. Control subjects were patients who completed a 14-day isolation period and had been officially declared recovered by healthcare professionals. The dependent variable was the mortality of COVID-19 patients in the January 2021 period. The independent variables consisted of demographic data (age and sex), clinical symptoms (cough, runny nose, anosmia, diarrhea, headaches, abdominal pain, muscle pain, and nausea/vomiting), and comorbidities (hypertension, heart disease, and diabetes). Multivariate analysis was conducted using multiple logistic regression.
Results
The multiple logistic regression analysis revealed several factors associated with COVID-19 fatalities in Jakarta: age of 60 years or older (odds ratio [OR], 4.84; 95% CI, 3.00 to 7.80), male (OR, 2.38; 95% CI, 2.41 to 3.68), dyspnea (OR, 3.93; 95% CI, 2.04 to 7.55), anosmia (OR, 0.13; 95% CI, 0.04 to 0.46), and heart disease (OR, 4.38; 95% CI, 1.04 to 18.46).
Conclusions
The control and prevention of COVID-19 among elderly individuals require particular vigilance. When a COVID-19 case is detected within this demographic, prompt treatment and medication administration are crucial to mitigate the presenting symptoms.

Abstract PDF Supplementary Material: Objectives
This study aimed to adapt the survey questionnaire designed by Moens et al. (2021) and determine the validity and reliability of the Arabic version of the survey in a sample of the Saudi population experiencing teleworking.
Methods
The questionnaire includes 2 sections. The first consists of 13 items measuring the impact of extended telework during the coronavirus disease 2019 (COVID-19) crisis. The second section includes 6 items measuring the impact of the COVID-19 crisis on self-view of telework and digital meetings. The survey instrument was translated based on the guidelines for the cultural adaptation of self-administrated measures.
Results
The reliability of the questionnaire responses was measured by Cronbach’s alpha. The construct validity was checked through exploratory factor analysis followed by confirmatory factor analysis (CFA) to further assess the factor structure. CFA revealed that the model had excellent fit (root mean square error of approximation, 0.00; comparative fit index, 1.0; Tucker-Lewis index, 1; standardized root mean squared residual, 0.0).
Conclusions
The Arabic version of the teleworking questionnaire had high reliability and good validity in assessing experiences and perceptions toward teleworking. While the validated survey examined perceptions and experiences during COVID-19, its use can be extended to capture experiences and perceptions during different crises.; Summary

Abstract PDF

Objectives
The purpose of this study was to assess the organizational effectiveness of the introduction of a healthcare information system (electronic medical records and databases) in healthcare in Kazakhstan.
Methods
The authors used a combination of 2 methods: expert assessment and strengths, weaknesses, opportunities, and threats (SWOT) analysis. SWOT analysis is a necessary element of research, constituting a mandatory preliminary stage both when drawing up strategic plans and for taking corrective measures in the future. The expert survey was conducted using 2 questionnaires.
Results
The study involved 40 experts drawn from specialists in primary healthcare in Aktobe: 15 representatives of administrative and managerial personnel (chief doctors and their deputies, heads of medical statistics offices, organizational and methodological offices, and internal audit services) and 25 general practitioners.
Conclusions
The following functional indicators of the medical and organizational effectiveness of the introduction of information systems in polyclinics were highlighted: first, improvement of administrative control, followed in descending order by registration and movement of medical documentation, statistical reporting and process results, and the cost of employees’ working time. There has been no reduction in financial costs, namely in terms of the costs of copying, delivery of information in paper form, technical equipment, and paper.

Abstract Summary PDF Supplementary Material

Objectives
Women experience more stress in middle age than in other periods of their lives. Therefore, health management programs that enable middle-aged women to cope with and manage stress are needed. This study investigated the psychological effects of a meditation-focused forest therapy program among 53 middle-aged women living in urban areas in Korea.
Methods
Participants were divided into 2 groups: one group underwent the program for 3 days in a forest, followed by 3 days in an urban environment, and the other group underwent the program for 3 days in the urban environment, followed by 3 days in the forest. The psychological effects of the forest therapy program were evaluated using the Profile of Mood States-Brief (POMS-B). Differences in mood state before and after the program conducted in the forest (experimental group) and in the urban environment (control group) were evaluated using the paired-samples t-test.
Results
The program in the forest significantly reduced tension, depression, anger, fatigue, and confusion among the domains of the POMS-B. The program in the urban area significantly reduced tension, but not depression, anger, fatigue, or confusion.
Conclusions
Meditation-focused forest therapy programs are expected to contribute to promoting psychological health and enhancing the quality of life of middle-aged women.

Abstract Summary PDF

A retrospective record-linkage study (RLS) based on medical records containing drug prescription histories involves immortal time bias (ITB). Thus, it is necessary to control for this bias in the research planning and analysis stages. Furthermore, a summary of a metaanalysis including RLSs that did not control for ITB showed that specific drugs had a preventive effect on the occurrence of the disease. Previous meta-analytic results of three systematic reviews evaluating the association between statin intake and gastric cancer risk showed that the summary hazard ratio (sHR) of the RLSs was lower than 1 and was statistically significant. We should consider the possibility of ITB in the sHR of RLSs and interpret the results carefully.

Abstract PDF

Objectives
This study provides insights on the impact of a targeted intervention (TI) programme on behaviour change among injecting drug users (IDUs) in India.
Methods
This paper examined the data from the Integrated Biological and Behavioural Surveillance 2014-2015 for IDUs in India. Logistic regression was performed to understand the factors (TI programme services) that affected injecting risk behaviours by adjusting for covariates. Propensity score matching was conducted to understand the impact of the TI programme on using new needles/syringes and sharing needles/syringes in the most recent injecting episode by accounting for the covariates that predicted receiving the intervention.
Results
Participants who received new needles and syringes from peer educators or outreach workers were 1.3 times (adjusted odds ratio, 1.29; 95% confidence interval [CI], 1.09 to 1.53) more likely to use new needles/syringes during most recent injecting episode than participants who did not receive needles/syringes. The matched-samples estimate (i.e., average treatment effect on treated) of using new needles in the most recent injecting episode showed a 2.8% (95% CI, 0.0 to 5.6) increase in the use of new needles and a 6.5% (95% CI, -9.7 to -3.3) decrease in needle sharing in the most recent injecting episode in participants who received new needles/syringes. There was a 2.2% (95% CI, -3.8 to -0.6) decrease in needle sharing in the most recent injecting episode among participants who were referred to other services (integrated counselling and testing centre, detox centres, etc.).
Conclusions
The TI programme proved to be effective for behaviour change among IDUs, as substantiated by the use of new needles/syringes and sharing of needles/syringes.

Abstract Summary PDF Supplementary Material

We aimed to review the current data composition of the Korean Tuberculosis and Post-Tuberculosis Cohort, which was constructed by linking the Korean Tuberculosis Surveillance System (KNTSS; established and operated by the Korean Disease Control and Prevention Agency since 2000) and the National Health Information Database (NHID; established by the National Health Insurance Service in 2012). The following data were linked: KNTSS data pertaining to patients diagnosed with tuberculosis between 2011 and 2018, NHID data of patients with a history of tuberculosis and related diseases between 2006 and 2018, and data (obtained from the Statistics Korea database) on causes of death. Data from 300 117 tuberculosis patients (177 206 men and 122 911 women) were linked. The rate of treatment success for new cases was highest in 2015 (86.7%), with a gradual decrease thereafter. The treatment success rate for previously treated cases showed an increasing trend until 2014 (79.0%) and decreased thereafter. In total, 53 906 deaths were confirmed among tuberculosis patients included in the cohort. The Korean Tuberculosis and Post-Tuberculosis Cohort can be used to analyze different measurement variables in an integrated manner depending on the data source. Therefore, these cohort data can be used in future epidemiological studies and research on policy-effect analysis, treatment outcome analysis, and health-related behaviors such as treatment discontinuation.

Summary

Korean summary
TB Post 코호트(Korean Tuberculosis and Post-Tuberculosis Cohort)는 한국의 결핵 모니터링 및 관리에 대한 인구집단 수준에서의 새로운 근거를 마련하고자 구축한 우리나라 결핵 환자 코호트입니다. 국가 결핵감시체계의 일환으로 구축된 질병관리청의 결핵신고자료와 국민건강보험공단의 국민건강정보DB 자료, 통계청 사망원인 자료의 연계로 구축되었으며, 각 자료원이 보유한 정보를 활용하여 통합적인 결핵 환자 연구가 가능할 것으로 기대하고 있습니다. 결핵의 정책 효과 연구뿐만 아니라, 치료 성공, 실패, 중단 등 치료결과에 대한 영향 요인 및 환자들의 건강 관련 행태에 대한 역학 연구 등 향후 다양한 연구에 활용될 수 있을 것으로 기대됩니다.

Objectives
No systematic review has explored the challenges related to worldwide universal health coverage (UHC). This study reviewed challenges on the road to UHC.
Methods
A systematic electronic search of all studies that identified the challenges of worldwide UHC was conducted, without any restrictions related to the publication date or language. A hand search and a bibliographic search were also conducted to identify which texts to include in this study. These sources and citations yielded a total of 2500 articles, only 26 of which met the inclusion criteria. Relevant data from these papers were extracted, summarized, grouped, and reported in tables.
Results
Of the 26 included studies, 7 (27%) were reviews, 6 (23%) were reports, and 13 (50%) had another type of study design. The publication dates of the included studies ranged from 2011 to 2020. Nine studies (35%) were published in 2019. Using the World Health Organization conceptual model, data on all of the challenges related to UHC in terms of the 4 functions of health systems (stewardship, creating resource, financing, and delivering services) were extracted from the included studies and reported.
Conclusions
This study provides a straightforward summary of previous studies that explored the challenges related to UHC and conducted an in-depth analysis of viable solutions.

Abstract Summary PDF Supplementary Material

Objectives
Socioeconomic disadvantages interact with numerous factors which affect geriatric mental health. One of the main factors is the social relations of the elderly. The elderly have different experiences and meanings in their social lives depending on their socio-cultural environment. In this study, we compared the effects of social relations on depression among the elderly according to their living arrangement (living alone or living with others) and residential area.
Methods
We defined social relations as “meetings with neighbors” (MN). We then analyzed the impact of MN on depression using data from the Korean Longitudinal Study of Aging Panel with the generalized estimating equation model. We also examined the moderating effect of living alone and performed subgroup analysis by dividing the sample according to which area they lived in.
Results
MN was associated with a reduced risk of depressive symptoms among elderlies. The size of the effect was larger in rural areas than in large cities. However, elderly those who lived alone in rural areas had a smaller protective impact of MN on depression, comparing to those who lived with others. The moderating effect of living alone was significant only in rural areas.
Conclusions
The social relations among elderlies had a positive effect on their mental health: The more frequent MN were held, the less risk of depressive symptoms occurred. However, the effect may vary depending on their living arrangement and environment. Thus, policies or programs targeting to enhance geriatric mental health should consider different socio-cultural backgrounds among elderlies.

Summary

Abstract Summary PDF

In 2020, the coronavirus disease 2019 (COVID-19) pandemic has caused unprecedented disruptions to global health systems. The Korea has taken full-fledged actions against this novel infectious disease, swiftly implementing a testing-tracing-treatment strategy. New obligations have therefore been given to the Health Insurance Review and Assessment Service (HIRA) to devote the utmost effort towards tackling this global health crisis. Thanks to the universal national health insurance and state-of-the-art information communications technology (ICT) of the Korea, HIRA has conducted far-reaching countermeasures to detect and treat cases early, prevent the spread of COVID-19, respond quickly to surging demand for the healthcare services, and translate evidence into policy. Three main factors have enabled HIRA to undertake pandemic control preemptively and systematically: nationwide data aggregated from all healthcare providers and patients, pre-existing ICT network systems, and real-time data exchanges. HIRA has maximized the use of data and pre-existing network systems to conduct rapid and responsive measures in a centralized way, both of which have been the most critical tactics and strategies used by the Korean healthcare system. In the face of new obligations, our promise is to strive for a more responsive and resilient health system during this prolonged crisis.

Objectives
Recent studies have suggested that assessing handgrip strength (HGS) asymmetry together with HGS may be helpful for evaluating problems in geriatric patients. This study aimed to identify whether HGS asymmetry, weakness, or both were associated with depression in Korean older adults.
Methods
This study included 4274 subjects from the sixth and seventh Korea National Health and Nutrition Examination Survey. Depression was measured using the Patient Health Questionnaire-9. The maximum HGS of the dominant hand was used as a representative value. HGS symmetry was categorized by the ratio of the HGS of the dominant hand to that of non-dominant hand. The odds ratio (OR) for depression was calculated according to the HGS and its symmetry.
Results
In total, 240 (12.5%) men and 534 (22.7%) women had depression. HGS or HGS asymmetry showed no statistically significant associations with depression in elderly men. Elevated odds of depression were observed in elderly women with low HGS (OR, 1.93; 95% confidence interval [CI], 1.33 to 2.81) or prominent HGS asymmetry (OR, 1.46; 95% CI, 1.02 to 2.08). There was a positive additive interaction between asymmetric HGS and weakness, as women with low and prominently asymmetric HGS showed higher odds of depression (OR, 3.77; 95% CI, 2.16 to 6.59) than women with high and symmetric HGS.
Conclusions
Depression in elderly Korean women was associated with both low and asymmetric HGS. Our findings support the potential value of HGS asymmetry as an indicator of HGS.

Abstract PDF

Objectives
The distribution of hospitals in Korea is unbalanced in terms of accessibility. Many local public health centers (PHCs) exempt out-of-pocket payments (OOPs) based on local government laws to increase coverage. However, this varies across administrative regions, as many make this exemption for the elderly, while others do not. This study aimed to evaluate the effects of the OOP exemption at local PHCs among elderly individuals.
Methods
This study used online data on Korean national law to gather information on individual local governments’ regulations regarding OOP exemptions. Individual-level data were gathered from the 2018 Community Health Survey and regional-level data from public online sources.
Results
The study analyzed 132 regions and 44 918 elderly people. A statistical analysis of rate differences and 2-level multiple logistic regression were carried out. The rate difference according to whether elderly individuals resided in areas with the OOP exemption was 1.97%p (95% confidence interval [CI], 1.07 to 2.88) for PHC utilization, 1.37%p (95% CI, 0.67 to 2.08) for hypertension treatment, and 2.19%p (95% CI, 0.63 to 3.74) for diabetes treatment. The regression analysis showed that OOP exemption had an effect on hypertension treatment, with a fixed-effect odds ratio of 1.25 (95% CI, 1.05 to 1.48).
Conclusions
The OOP exemption at PHCs can affect medical utilization in Korea, especially for hypertension treatment. The OOP exemption should be expanded to improve healthcare utilization in Korea.

This study investigated the effects of socio-demographic factors on the decreasing trend in the sex ratio at birth from 1997 to 2017 in Korea.
Methods
Data from 10 349 602 live births registered with Statistics Korea from 1997 to 2017 were analyzed. The secondary sex ratio (SSR), defined as the ratio of male to female live births, during the study period (1997-1999 [phase I], 2000-2002 [phase II], 2003-2005 [phase III], 2006-2008 [phase IV], 2009-2011 [phase V], 2012-2014 [phase VI], and 2015-2017 [phase VII]) was calculated according to selected socio-demographic factors, such as parental age, education, occupation, and birth order. Logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals for a male birth after adjusting for potential confounders.
Results
The SSR gradually decreased from 1.10 (in 1998-2000 and 2002) to 1.05 (in 2013-2016). While a decreasing trend in the SSR was not noted among first births, male-biased sex ratios were prominent among third and higher-order births, for which the highest SSR was 1.46 in 1998. Higher birth order was significantly associated with an excess of male births in phases I-VI (≥third vs. first, OR range, 1.03 to 1.35). Advanced maternal age was significantly associated with an excess of female births in phases II, III, and V (≥40 vs. 20-24 years, OR range, 0.92 to 0.95).
Conclusions
This study demonstrated that advanced maternal age and reduction of the artificially-biased SSR among third and higher-order births may partially explain the decreasing trend in the SSR from 1997 to 2017 in Korea.; Summary

Objectives
This study aimed to evaluate the association between dental implants and cognitive function in community-dwelling older adults.
Methods
Data were collected from the baseline survey (2016-2017) of the Korean Frailty and Aging Cohort Study. The study sample comprised 1115 community-dwelling people aged 70 years to 84 years who had 0-19 natural teeth. Dental implants and natural teeth were identified by panoramic radiography, while the cognitive function was assessed by the Korean version of the Mini-Mental State Examination (MMSE-KC). The association between dental implants and cognitive function was analyzed by multiple linear regression. Sensitivity analysis was performed to test for potential bias.
Results
The mean number of natural teeth in the study population was 9.50 (standard deviation [SD], 6.42), and the mean MMSE-KC score was 24.93 (SD, 3.55). In the simple univariate analysis, tooth replacement, age, sex, smoking status, alcohol consumption, body mass index, osteoporosis, number of natural teeth, periodontitis, chewing discomfort, tooth-brushing frequency, education level, monthly household income, participation in economic activity, living alone, and marital status had a significant impact on the association. After adjusting for confounders, the association between dental implants and cognitive function remained significant (B, 0.85; standard error, 0.40; p<0.05). Age, body mass index, periodontitis, tooth-brushing frequency, and education level were also significantly associated with cognitive function. The results of the sensitivity analyses were consistent with those of the primary analysis.
Conclusions
Dental implants were associated with cognitive function in older adults living in the community. Dental implants as tooth replacements may play a role in preserving cognitive function.

Abstract Summary PDF

Objectives
Estimating influenza-associated mortality is important since seasonal influenza affects persons of all ages, causing severe illness or death. This study aimed to estimate influenza-associated mortality, considering both periodic changes and age-specific mortality by influenza subtypes.
Methods
Using the Microdata Integrated Service from Statistics Korea, we collected weekly mortality data including cause of death. Laboratory surveillance data of respiratory viruses from 2009 to 2016 were obtained from the Korea Centers for Disease Control and Prevention. After adjusting for the annual age-specific population size, we used a negative binomial regression model by age group and influenza subtype.
Results
Overall, 1 859 890 deaths were observed and the average rate of influenza virus positivity was 14.7% (standard deviation [SD], 5.8), with the following subtype distribution: A(H1N1), 5.0% (SD, 5.8); A(H3N2), 4.4% (SD, 3.4); and B, 5.3% (SD, 3.7). As a result, among individuals under 65 years old, 6774 (0.51%) all-cause deaths, 2521 (3.05%) respiratory or circulatory deaths, and 1048 (18.23%) influenza or pneumonia deaths were estimated. Among those 65 years of age or older, 30 414 (2.27%) all-cause deaths, 16 411 (3.42%) respiratory or circulatory deaths, and 4906 (6.87%) influenza or pneumonia deaths were estimated. Influenza A(H3N2) virus was the major contributor to influenza-associated all-cause and respiratory or circulatory deaths in both age groups. However, influenza A(H1N1) virus–associated influenza or pneumonia deaths were more common in those under 65 years old.
Conclusions
Influenza-associated mortality was substantial during this period, especially in the elderly. By subtype, influenza A(H3N2) virus made the largest contribution to influenza-associated mortality.

Korean summary
계절 인플루엔자는 심각한 호흡기 합병증으로 진행할 수 있어 질병 부담의 추산이 중요한 질병이다. 현재까지는 연령별, 인플루엔자 연관 사망을 정확하게 추산하기 어려웠으나, 본 연구에서는 이를 추산하기 위해 고안된 다양한 방법 중 음이항 회귀 분석을 이용하여 2009년부터 2016년간 인플루엔자 아형별 연관 사망을 추산하였다. 그 결과, 전체 사망자 중 65세 미만에서 약 6,774명, 65세 이상에서 약 30,414명의 연간 인플루엔자 사망이 추산되었고, 이는 특히 인플루엔자 아형 중 전체 연령에서 A(H3N2) 연관 사망이 가장 많은 비율을 차지했다.

Abstract Summary PDF

Objectives
Presenteeism is currently recognized as a significant global health issue that can potentially cause productivity losses. Hence, many studies have analyzed the relationships between workplace factors and presenteeism. However, few studies have considered non-occupational factors. This study examined the associations between presenteeism and activities outside work, including volunteering, self-development, leisure/sports, and gardening and house repair activities, in Korean wage workers.
Methods
This study analyzed the fourth Korean Working Conditions Survey, in which a total of 19 294 wage workers participated. To identify relationships between presenteeism and activities outside work, multivariate logistic regression analysis was used after adjusting for general and occupational characteristics.
Results
Self-development and leisure/sports activities significantly increased the odds ratio (OR) of presenteeism (OR, 1.166; 95% confidence interval [CI], 1.061 to 1.282 and OR, 1.276; 95% CI, 1.181 to 1.379, respectively).
Conclusions
Certain activities outside work, such as self-development or leisure/sports, were related to presenteeism among Korean wage workers. Although many previous studies have emphasized the positive effects of those activities on health, this study documented negative effects of these activities outside work on health.

본 연구는 제4차 근로환경조사를 통해 한국인 임금근로자들에서 다양한 ‘업무 외 활동’과 프리젠티즘과의 연관성을 알아보았다. 자기계발 및 레저/스포츠활동 등의 ‘업무 외 활동’에 참여할 경우 프리젠티즘 위험도가 상승했으며, 이를 통해 자기계발의 긍정적인 역할을 강조 하였던 기존 연구들과는 달리 ‘업무 외 활동’의 부정적인 면을 확인 할 수 있었다.

Abstract Summary PDF

Objectives
The aim of this study was to evaluate the impact of shifts in maternal age and parity on the increasing trends in the low birth weight (LBW) and very low birth weight (VLBW) rates from 2005 to 2015 in South Korea.
Methods
Data from 4 993 041 live births registered with Statistics Korea during the period between 2005 and 2015 were analyzed. Applying a modified standardization method, we partitioned the total increment in the LBW and VLBW rates into (1) the increase in the LBW and VLBW rates due to changes in the maternal age and parity distribution (AP-dis) and (2) the increase due to changes in the age-specific and parity-specific rates (AP-spe) of LBW and VLBW for singleton and multiple births, respectively.
Results
During the study period, the total increment in the LBW and VLBW rates was 1.43%p and 0.25%p, respectively. Among singleton births, changes in the AP-dis accounted for 79% (0.34%p) and 50% (0.06%p) of the total increment in the LBW and VLBW rates, respectively. Meanwhile, among multiple births, changes in the AP-dis did not contribute to the increase in the LBW and VLBW rates, with 100% of the increase in the LBW (1.00%p) and VLBW (0.13%p) rates being attributed to changes in the AP-spe.
Conclusions
This study demonstrated that shifts in maternal age and parity were prominent contributors to the increase in the LBW and VLBW rates among singleton births between 2005 and 2015 in South Korea.
