Objectives: The purpose of this paper was to analyze the relevance between elderly’s subjective social support and drinking behavior. Methods: This study investigated the elderly aged over 65. A total of 1424 samples were collected by door-to-door interview to investigate subjective social support, smoking, drinking, drinking behavior, average sleeping hours and the number of sleeplessness. In order to test the statistical significance of the difference in health behaviors including smoking, drinking, average sleeping hours and the number of sleeplessness according to the subjective social support, we used cross analysis. Logistic regression analysis that set subjective social health as dependent variable was also conducted to examine the influence of smoking, drinking, average sleeping hours and the number of sleeplessness on subjective social support. Results: Male has higher social support than female, and married has higher social support than unmarried. 32% of elderly were drinking alcohol. By sexuality, male's drinking rate was 55.6% and female's drinking rate was 44.4%. Group with high subjective social support has higher drinking rate than group with low subjective social support. In analysis of social support according to the sexuality and age, male than female, older age and higher social support has higher drinking rate. To examine the influence of subjective social support on drinking behavior, we set the subjective social support as dependent variable. The logistic regression analysis which set subjective social support as dependent variable showed that male than female, married than unmarried has higher subjective social support. Also, group with higher subjective social support showed higher drinking rate. Conclusion: Through this study, we could find that subjective social support and drinking has statistical relevance. Drinking is the medium to attain social support, so they have relevance. Therefore, local community needs to provide education for moderation of drinking, and to develop the programs to enhance social support.
