Individual-level associations between indicators of social capital and alcohol use disorders identification test scores in communities with high mortality in Korea

Abstract

Objectives: This study examined associations among social capital indicators (social participation and generalized trust) at the individual level and alcohol use, which was quantified using Alcohol Use Disorders Identification Test (AUDIT) scores. Methods: In total, there were 8800 participants in community health interviews, including 220 adults sampled systematically from a resident registration database of each of 40 sub-municipal administrative units of local (city or county) governments. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were calculated using polychotomous logistic regression. Results: The aORs for abstainers versus people with AUDIT scores of 0-7, based on 3 questions on generalized trust, in comparison to those with no positive responses, were 1.15 (95% CI, 0.99 to 1.34) for 1 positive response, 1.16 (95% CI, 0.98 to 1.37) for 2 positive responses; and 1.39 (95% CI, 1.20 to 1.61) for 3 positive responses. The aORs for abstainers versus people with AUDIT scores of 0-7, in comparison to participation in no organizations, were 0.61 (95% CI, 0.54 to 0.69) for participation only in informal organizations; 2.16 (95% CI, 1.57 to 2.99) for participation only in religious organizations; 2.41 (95% CI, 1.10 to 5.29) for participation only in volunteer organizations; and 0.65 (95% CI, 0.57 to 0.74) for participation in formal organizations. Participants in formal social organizations, regardless of their participation in informal organizations, were more likely to have AUDIT scores of 8-15 (aOR, 1.29; 95% CI, 1.04 to 1.60) or ≥16 (aOR, 1.65; 95% CI, 1.22 to 2.23) than to have scores of 0-7. Conclusions: Our findings may have implications for health policy to reduce alcohol problems. Copyright ? 2020 The Korean Society for Preventive Medicine.
