Objectives: This study examined the association between participation in economic activity and depression among older adults by dividing them into the young-old (65–74 years) and old-old (≥75 years). It also investigated the differential effects of related factors on depression with each age group. Methods: Using data from the 2022 Korean Longitudinal Study of Ageing (KLoSA), we analyzed data from 4,491 individuals aged 65 years and older. Multivariatle logistic regression was conducted based on the Social Determinants of Health framework to identify factors associated with depression. Results: Economic activity participation was not significantly associated with depression in either group. However, having ≥4 chronic diseases increased depression risk across both groups. Among the old-old, declines in IADL and smoking status were significantly associated with depression, whereas regular exercise was protective only in the young-old. Better subjective health consistently reduced depression risk in both groups. Conclusions: These findings have practical implications for mental health and welfare policies intended for older adults and highlight the importance of age-specific and tailored intervention strategies in a post-aged society.
