Neighborhood Social and Physical Environments and Sedentary Behaviors: Importance of Early Childhood in Shaping Health Behaviors.

Abstract

This study aims to investigate the persistence of sedentary behaviors from early childhood to adolescence and the longitudinal association between neighborhood social and physical environments and childhood sedentary behaviors. Using the Future of Families & Child Wellbeing Study (N = 2716), we conducted a cross-lagged path analysis to examine the longitudinal association between neighborhood social and physical environments (neighborhood socioeconomic status, observed physical disorder, and crime rates) and sedentary behaviors at subsequent measurement points, after controlling for demographic factors and family socioeconomic status. We observed the continuity of sedentary behaviors in early childhood, extending throughout adolescence. Neighborhood socioeconomic status was significantly associated with sedentary behaviors at subsequent measurement points from early childhood to adolescence. Observation-based physical disorder and crime rates were associated with engagement in greater sedentary behaviors in adolescence but not in early and middle childhood. We also observed a partial mediation effect of neighborhood physical disorder and crime rates in the association between neighborhood socioeconomic status and sedentary behaviors in adolescence. Our results demonstrated the importance of early childhood in shaping healthy behaviors and highlighted the contribution of unfavorable environments to sedentary behaviors. These findings call for the need to support disadvantaged neighborhoods, particularly by addressing safety concerns and physical disorder, for promoting physical activity and reducing sedentary behaviors among adolescents.
