Walkable Neighborhoods and Cognition: Implications for the Design of Health Promoting Communities.

This study seeks to examine neighborhood characteristics, physical activity, and health status and their roles in promoting healthy cognitive aging. Using data from the REasons for Geographic And Racial Difference in Stroke (REGARDS) study (=10,289, mean age=73.4 years), we used multilevel linear regression to examine the relationships between walkable neighborhoods (both objectively measured and subjective perceptions), walking behavior, physical activity, health status, and cognitive function. Engaging in any moderate physical activity (β=0.47, < 0.001), having better health status (β=0.02, < 0.001), living in neighborhoods with greater street connectivity (β=0.15, < 0.05), and positive perceptions of neighborhood traffic ( < 0.01) and parks ( < 0.05), were associated with higher cognitive function. Residence in socioeconomically disadvantaged neighborhoods (β=-0.01, < 0.01) was negatively associated with cognitive function Both perceived and objective features of walkable environments may have consequences for cognitive health, and can inform the development of health promoting communities.
