Abstract
BACKGROUND: Rural areas in Korea are experiencing both super-aging and depopulation, creating critical gaps in health and social care. Using a citizen participatory approach, we sought to address the care gaps for older adults in rural areas. This study examined the changes in frailty and depressive symptoms observed during a citizen-led intervention. METHODS: This study is a single- arm pre-post quasi-experimental design. A 12-week intervention was implemented using local citizens as care providers. Intervention components included identifying and planning individual care needs, providing health education, organizing tailored community activities, and conducting AI-assisted weekly check-up calls to monitor health status. RESULTS: Changes appeared more pronounced among vulnerable subgroups. Older adults with frailty showed an observed decrease in depressive symptoms compared to those with prefrailty or robust status. Conversely, among those with depressive symptoms, frailty levels appeared to increase more slowly than those without depressive symptoms. These patterns are consistent with the previously reported bidirectional associations between frailty and depression and may reflect the tendency for changes in one domain to coincide with changes in the other, rather than indicating a causal influence. CONCLUSION: This citizen-led care intervention showed more noticeable short-term changes among older adults with higher vulnerability, particularly those with frailty or depressive symptoms. These findings indicate potential roles for citizen participation in enhancing social support and supporting ongoing monitoring in rural depopulation areas. The results suggest that citizen participation is a potentially feasible and sustainable approach to care systems in aging, resource-limited communities.
