Objectives : The purpose of this research is to measure the level of individual social capital, to identify the relationships between social capital and self-rated health, and to reveal how the administrative section(dong, eup, and myeon), sex, and age might modify the relationships.
Methods : This study used the data from a big health survey done at Gyeongsangnam-do Province in 2008. The study subjects were 6,500 adults randomly sampled from 20 counties. Trained interviewers visited their houses and interviewed them using structured questionnaires. The social capital was measured with 'participation in formal and/or informal group' and 'trust' using responses to three questions. The health behaviors included smoking, drinking, sleep hours, regular exercises, regular breakfast, and stress level. The self-rated health level was the answer to the question of 'How do rate your health?' The level of participation and trust were compared regarding to sex, age, and administrative section (dong, eup, and myeon). The association of social capital with self-rated health was analysed using hierarchical logistic regression model. The independent variables were only social capital (participation and trust level) in model 1, plus socio-demographic variables in model 2, plus socio-demographic variables and health behaviors in model 3. The dependent variable was self-rated health (good versus bad).
Results: The proportions of the no participation tended to be higher in women, age group ≥65, and in the administrative section of myeon. The proportions of the lowest trust level tended to be higher in women, age group <65, and in the administrative section of myeon. The significant social capital variables associated with self-rated good health were both the level of participation [participation in informal group OR=1.25 (95% CI 1.09-1.44), participation in formal or both formal and informal group OR=1.19 (95% CI 0.96-1.48) compared with no participation] and trust level [one positive answer OR=1.15 (95% CI 0.97-1.38), two positive answers OR=1.23 (95% CI 1.03-1.47), three positive answers OR=1.34 (95% CI 1.14-1.56) compared with no positive answer] in model 3. The positive association between social capital (both participation and trust) and self-rated good health remained significant in the subgroups of dong, age group <65, and men in stratified analysis. However, in the subgroups of myeon, age group ≥65, and women only trust level remained significant.
Conclusion: In conclusion, this study showed that self-rated good health was positively associated with social capital measured with participation and trust. Health policy encouraging participation and trust to improve health should be considered.
