Social network, perceived satisfaction with neighborhoods and depressive symptoms among older adults in Korea.

The coronavirus disease 2019 (COVID-19) pandemic has significantly affected social networks and perceived satisfaction with neighborhoods, potentially affecting the mental health of older adults. This study investigated the changes in these factors and their association with depressive symptoms among Korean older adults before and during the COVID-19 pandemic. The prevalence of depressive symptoms slightly increased during the pandemic (4.7-4.9%). Social networks weakened, whereas perceived neighborhood satisfaction improved. Notably, the protective effect of social networks against depressive symptoms became stronger during the pandemic, particularly among low-income individuals and those living in rural areas. Maintaining social networks is essential for promoting mental health resilience among older adults, especially during crises. Policymakers should thus prioritize interventions that strengthen community cohesion, provide governmental support, and facilitate social networking opportunities for vulnerable populations.
