Age-Friendly Environment and Health among Older Americans

My dissertation focuses on investigating the associations of neighborhood environments—namely, built and social environments—with health among community-dwelling older Americans. The first paper examines groupwide variations in social participation patterns among older adults before and during the COVID-19 pandemic, and if community social cohesion and health during the pandemic were significantly associated with social participation patterns. Using Rounds 9 and 10 longitudinal data from the National Health and Aging Trend Study, I employed latent class analysis to identify the presence of groupwide variations in social participation, before and during the pandemic. I used logistic and linear regressions to examine the associations between social participation patterns, community social cohesion, and health during the pandemic. Results suggested two participation patterns, active and selective participants. Compared to active participants, older adults who were selective in their social participation were more likely to live in less socially cohesive communities and report substantial depressive and anxiety symptoms. In the second paper, I examined cross-sectional and longitudinal relationships between neighborhood physical disorder, low social cohesion, and sleep problems among older Americans. Mediators of health behaviors (i.e., lack of physical activity and social participation) and mental health (i.e., depressive and anxiety symptoms) were also tested in these relationships. Data were derived from three rounds of panel data (Rounds 7-9) from the National Health and Aging Trends Study, involving a sample of 4,029 Americans aged 65 or older. I found statistically significant cross-sectional and longitudinal associations between physical disorder and low social cohesion, and late-life sleep problems. Only cross-sectional mediation effects of health behaviors and mental health were found in the relationship of physical disorder and sleep problems, whereas both cross-sectional and longitudinal associations ...
