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.

AbstractAbstract AbstractSummary PDFSupplementary Material
Objectives
This study aimed to investigate the current status of social isolation and seclusion among young adults in Korea and to analyze their association with suicide risk.
Methods
We utilized data from 14 966 young adults aged 19-34 years from the 2022 Survey on the Lives of Young People. Social isolation and seclusion were defined as independent variables, and suicidal ideation within the past year was set as the dependent variable. Propensity score matching (PSM) was employed to reduce the risk of selection bias, and logistic regression analysis was conducted to examine the associations between social isolation, seclusion, and suicidal ideation.
Results
Of the participants, 266 individuals (1.8%) were socially isolated, and 67 individuals (0.5%) were secluded. Associations were observed between social isolation and suicidal ideation (population-weighted adjusted model: odds ratio [OR], 2.43, p=0.003; population-weighted PSM model: OR, 2.03, p=0.037), as well as between seclusion and suicidal ideation (population-weighted adjusted model: OR, 4.15, p=0.004; population-weighted PSM model: OR, 3.87, p=0.010) across all models.
Conclusions
Being socially isolated or secluded is associated with an increased risk of suicidal ideation among young adults aged 19-34 years. Preventive policies and tailored support systems are urgently needed to address these risks. This study contributes to the development of specific policies for mitigating social isolation and supporting the reintegration of young adults aged 19-34 years into society.

Korean summary
본 연구는 2022년 청년 삶 실태조사 원자료를 이용하여 한국 청년의 사회적 고립·은둔과 자살 생각의 연관성을 분석하였다. 연구 결과, 사회적으로 고립되거나 은둔하는 청년은 그렇지 않은 청년에 비해 자살 생각을 할 위험이 유의하게 높은 것으로 나타났다. 이는 고립·은둔 청년들의 자살 위험성을 확인하고, 이들의 사회 재통합을 돕기 위한 예방적 정책과 맞춤형 지원 시스템 마련이 시급함을 시사한다.
Key Message
Using data from the 2022 Survey on the Lives of Young People, this study demonstrates that young adults (aged 19-34) in Korea experiencing social isolation or seclusion face a significantly increased risk of suicidal ideation. These findings identify socially isolated and secluded young people as a critical high-risk group for suicide. This underscores the urgent need for proactive public health policies and tailored support systems to prevent suicide by addressing social isolation and seclusion and promoting societal reintegration among this vulnerable population.

AbstractAbstract 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.
