Abstract
Background: Social capital is gaining more attention as an important factor of health-related quality of life (HRQOL). However, studies of the association between social capital and HRQOL among the elderly in rural areas are sparse, even though social capital could have a more profound effect on these people compared to those from other areas and other age groups. Methods: A self-administered questionnaire was constructed to gather information on demographic variables, health behaviors, chronic diseases, HRQOL (KEQ-5D), social capital (adapted from the Integrated Questionnaire for measurement of Social Capital: SC-IQ). This questionnaire was administered to 167 residents of Chuncheon City, Gangwon Province, Korea. Multiple regression method was applied to examine the association between SC-IQ and KEQ-5D scores. Results: Of 167 participants, 40.7% were male and 59.3% were female. Mean ages were $59.04{\pm}16.07$ years and $62.86{\pm}17.00$ years, respectively. Among three levels of social capital, an increase in community level score was significantly associated with greater anxiety and depression, which was presented as an increased KEQ-5D Anxiety/Depression domain score (adjusted OR 1.049, 95% confidence interval 1.022-1.076) and with a higher overall HRQOL, which was presented as an increased KEQ-5D VAS score (${\beta}$=0.028, P=0.024). Conclusions: Among this group of elderly people from one rural community, enriched social capital of community level based on trusting relationships was associated with better overall HRQOL and emotional health.
연구배경: 농촌 사회의 노인은 그 특성상 사회자본이 건강관련 삶의 질에 큰 영향을 미칠 수 있는 인구집단임에도 불구하고 이들 인구집단에 대한 사회자본과 건강관련 삶의 질에 대한 연구는 거의 이루어지지 않았다. 방법: 대상자의 인구사회학적 변수, 건강관련 행태, 만성질환 여부, 건강관련 삶의 질(KEQ-5D), 사회자본(번안 Integrated Questionnaire for measurement of Social Capital: SC-IQ)의 측정을 위한 자가 기입식 설문을 구성하여, 강원도 춘천시 거주 주민 167명에게 적용하였다. SC-IQ와 KEQ-5D의 점수 간의 관련성을 확인하기 위하여 다변량 회귀분석을 실시하였다. 결과: 총 167명의 대상자 중 40.7%는 남성이었고, 59.3%는 여성이었다. 각각의 평균연령은 59.04${\pm}$16.07세와 62.86${\pm}$17.00세였다. 사회자본 수준 중, 공동체 수준의 사회자본점수가 증가할수록 불안과 우울 영역의 점수가 개선되었으며(adjusted OR 1.049, 95% 신뢰구간 1.022-1.076), 전반적 건강관련 삶의 질을 나타내는 KEQ-5D VAS 점수 역시 개선되었다(${\beta}$=0.028, P=0.024). 결론: 고령자 중심의 농촌 지역 주민에 있어서, 신뢰관계에 기반을 둔 공동체 수준의 사회자본은 전반적 건강관련 삶의 질과 정서 건강의 향상과 관련성이 있다.
