Observational study reveals social support buffers depression-linked life satisfaction loss only in adults aged 75 and older, highlighting age-specific needs in solitary elders.

Key Points

To evaluate and compare how depression affects life satisfaction among young-old (65–74 years) and old-old (≥75 years) adults living alone, with an emphasis on the moderating role of social support.
Analyzed cross-sectional survey data from the ninth wave of the Korean Panel of Retirement and Income Study (KReIS).
Assessed 953 older adults living alone, categorized into young-old (65–74 years, n=313) and old-old (≥75 years, n=640) cohorts.
Evaluated the direct and moderating relationships among depression, perceived social support, and life satisfaction across both age groups.
Depression correlated inversely with life satisfaction, while social support correlated positively with life satisfaction across both young-old and old-old cohorts.
Social support exhibited a statistically significant moderating effect on the negative link between depression and life satisfaction exclusively among the old-old group (≥75 years).
