Leisure Time Physical Activity Mediates the Relationship Between Neighborhood Social Cohesion and Mental Health Among Older Adults.

Neighborhood social cohesion can contribute to leisure time physical activity (LTPA) involvement and psychological well-being. In spite of the value of neighborhood social cohesion for health benefits, there is a dearth of empirical study that explores how neighborhood social cohesion influences LTPA and mental health among older adults. Therefore, this study aimed to investigate the association among neighborhood social cohesion, light-to-moderate and vigorous LTPA, and mental health in a representative sample of U.S. older adults (n = 6,412). Structural equation modeling (SEM) analysis revealed that older adults who perceived neighborhood social cohesion were more likely to participate in light-to-moderate and vigorous LTPA, which in turn resulted in better mental health. This study confirmed the importance of neighborhood social cohesion in promoting older adults' health-related behaviors and mental health. The practical implications on how to promote mental health among older adults, as well as future research directions were discussed.
