abstract="OBJECTIVES: This study evaluated a neighborhood  environment survey and compared the physical activity and weight status of the  residents in 2 neighborhoods. METHODS: On 2 occasions, 107 adults from  neighborhoods with differing "walkability" were selected to complete a  survey on their neighborhood environment. Physical activity was assessed by  self-report and by accelerometer; height and weight were assessed by  self-report. RESULTS: Neighborhood environment characteristics had moderate to  high test-retest reliabilities. Residents of high-walkability neighborhoods  reported higher residential density, land use mix, street connectivity,  aesthetics, and safety. They had more than 70 more minutes of physical activity  and had lower obesity prevalence (adjusted for individual demographics) than did  residents of low-walkability neighborhoods. CONCLUSIONS: The reliability and  validity of self-reported neighborhood environment subscales were supported.  Neighborhood environment was associated with physical activity and overweight  prevalence.",
