Multilevel determinants of social frailty in community-dwelling older adults in South Korea: A cross-sectional study using Korean Community Health Survey

Social frailty in older adults is primarily influenced by individual characteristics with a modest community context effect. Targeted interventions for vulnerable individuals, including those who are older, female, low socioeconomic status, physically inactive, or experiencing depression, together with community-level efforts in highly aged areas such as improving social infrastructure and enhancing safety, are essential to reduce social frailty.
