Depression among older adults is a challenging public health concern in Korea. Using panel data from the Korea Institute for Health and Social Affairs on Korean older adults and their family caregivers, this study explores significant predictors of depression among Korean older adults as well as the moderating effect of living arrangements on the association between social integration and depression. A multivariate logistic regression analysis showed that preexisting depression was the most significant predictor of Korean older adults' current depression, followed by health status and family support. In addition, social integration significantly decreased Korean older adults' depression. Importantly, a significant moderation effect of living arrangements between Korean older adults' social integration and depression was observed. This study implies the development of individually tailored and culturally responsive programs to engage marginalized Korean older adults living alone, helping foster their well-being and optimal aging.
