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.
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.
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.
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.
Korean summary
본 연구는 사회적 관계가 노인의 우울에 미치는 영향이 독거 상태 및 거주 지역에 따라 달라지는지 확인하였다. 사회적 관계를 이웃과의 만남 빈도로 정의하고 고령화연구패널자료를 분석한 결과 사회적 관계의 효과 크기는 대도시에서 가장 작었고 독거의 조절효과는 농어촌에서만 유의하였다.

AbstractAbstract PDF
The effects of regional medical insurance on utilization of medical care in urban population was examined in this study. The data was collected in a 2-year follow-up household survey conducted at Taegu city before and after implementation of the regional medical insurance. The study population was divided into 2 groups. Cohort I was the uninsured in 1989 and cohort II was the insured in 1989. After the coverage of medical insurance, physician visit rate per 1,000 population, use-disability ratio and use-restricted activity ratio in cohort I were increased compared to cohort II in both of acute and chronically ill people. The use-disability ratio and use-restricted activity ratio of the insured poor were lower than those of the insured nonpoor in both of cohort I and cohort II. The major reasons for pharmacy use were accessibility and affordability before the coverage of medical insurance in cohort I, however, after the coverage of medical insurance, the important reason was accessibility rather than affordabifity. In logistic regression analysis of physician visit, the significant independent variables were acute illness episode(+), chronic illness episode(+) and income(+) in both of cohort I and cohort II. In cohort I, after the coverage of medical insurance, more people replied that the medical cost of hospital and clinic was reasonable. The people who covered by the regional medical insurance were more dissatisfied with the imposed premium than those who covered by other types of medical insurance in both of cohort I and cohort II. More people in cohort II than cohort I were dissatisfied with the services from hospitals and clinics after implementation of the regional medical insurance. In conclusion. after the coverage of medical insurance, the gap between the poor and the nonpoor still exists in terms of medical care utilization.
