This study examined the impact of family interaction frequency on the association between living alone and depressive symptoms among older adults aged \u226580 years using nationally representative survey data.Methods: Among the 229 099 participants of the 2019 Korea Community Health Survey, 15 672 participants aged \u226580 years who either lived with close family or lived alone were included in the analysis. Participants living alone were classified according to the frequency of family interaction, ranging from less than once a month to more than once a week. The outcome variable was moderate to severe depressive symptoms, defined as a Patient Health Questionnaire-9 score of \u226510.Results: The prevalence of depressive symptoms was higher among older adults living alone (9.4\u201314.1%, depending on the frequency of family interaction) than among those living with close family (6.5%). Older adults living alone who interacted with family less than once a month were more likely to report depressive symptoms compared with those living with close family (adjusted odds ratio [aOR], 1.71; 95% confidence interval [CI], 1.36 to 2.15). Weekly family interaction mitigated the impact of living alone on the prevalence of depressive symptoms (aOR 1.10; 95% CI, 0.84 to 1.42). The influence of family interaction on the association between living alone and depressive symptoms remained consistent across subgroups of men, women, and those with difficulty in daily activities.Conclusions: Encouraging regular interaction among family members could serve as an effective strategy to protect the mental health of older adults.<\/jats:p>","DOI":"10.3961\/jpmph.25.222","type":"journal-article","created":{"date-parts":[[2025,12,1]],"date-time":"2025-12-01T02:13:32Z","timestamp":1764555212000},"page":"86-94","update-policy":"https:\/\/doi.org\/10.3961\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The
