The purpose of this study is to explore how health and health behavior factors moderate the relation between socio-economic position(SEP) and Korean elderly people's self-rated health status. The data sources are from the Korean Longitudinal Study of Aging(2008). The analysis sample consists of 4,040 cases. Analysis of the results shows that health characteristics such as ADL, MMSE, geriatric depression, and pain are significant predictors of self-rated health status. In addition, exercise and drinking alcohol also prove to be factors influencing self-rated health status. Health factor such as MMSE and health behavior factors such as drinking alcohol served as moderators of the influences of SEP on one's self-rated health status. For example, higher MMSE provides a slight increase to the positive relationship between SEP and self-rated health status. In addition, those who responded yes to drinking alcohol, compared to those who responded no, provides an increase to the positive relationship between SEP and one's self-rated health status.
This study explores the moderating effects of income on the relationship between geriatric depression and health satisfaction among elderly individuals in Korea. The data were obtained from public data files in the 2011 Elderly Living Condition Survey database. The sample included 9,461 cases. The results show that the factors influencing health satisfaction were geriatric depression (β=-.510, p<.001), gender (β=.123, p<.001), activities of daily living (β=-.116, p<.001), income (β=.050, p<.001), living alone (β=.044, p<.001), and the area of residence (β=.017, p<.05). Income moderated the effect of geriatric depression on health satisfaction. Noteworthy is that an increase in income slightly weakened the negative relationship between geriatric depression and health satisfaction.
