This study examined the impact of late-life poverty on self-rated health, focusing on the mediating and moderating effects of health behaviors and social support. Despite the significant associations among poverty, health behaviors, and health outcomes, little studies have tested complex structural pathways among them. Thus, the purpose of this study is to identify multiple causal pathways between poverty and self-rated health, mediated and moderated by health behaviors and social support. To test the structural pathways, the structural equation modeling was utilized using the 2006 Korean Longitudinal Study of Aging data. The results of this study indicated that poverty had the direct negative impact not only on the health behaviors such as smoking and lack of regular exercise but also on the self-rated health. In addition, regular exercise significantly mediated the relationship between poverty and self-rated health. Finally, informal social support from family and friends buffered the negative impact of poverty on the self-rated health. Findings suggested that providing informal social support to the low income elderly is important in addition to the economic support. It is also necessary to develop programs for promoting healthy behaviors, especially regular exercise.
