Do neighborhood environments moderate the effect of physical activity lifestyle interventions in adults?

Abstract

This study builds upon the current literature investigating the relationship between individuals' physical activity and the built environment. This prospective study of two lifestyle interventions in adults explores the moderating effect of the built environment measured both objectively and by self-report. Results show that overweight men in an intervention group increased their walking significantly more if they lived in less walkable neighborhoods. Overweight women were more likely to increase their physical activity over time if they perceived better safety from traffic. This study suggests that psychosocial interventions can help men overcome environmental barriers to walking.
