Neighborhood built environment associations with adolescent's location-specific sedentary and screen time

Less is known about how neighborhood environments relate to sedentary time as compared to physical activity. This study examined relations of perceived and objective neighborhood environments with TV time, total screen time, total sedentary time, sedentary time at home, sedentary time in the home neighborhood, and time spent at home, in 524 12-16 year olds. Better perceived aesthetics and a perceived neighborhood environment index were related to less TV and screen time, and greater cul-de-sac density was related to less total and home sedentary time. Greater street connectivity, mixed land use, and an objective neighborhood environmental index were related to more total sedentary time. Findings suggest that some neighborhood environment attributes may not have the same potential influences on limiting sedentary time as they do for supporting physical activity.
