Neighborhood-based differences in physical activity: an environment scale evaluation.

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.

The association of neighborhood design and recreational environments with physical activity.

PURPOSE: To determine the association of neighborhood design factors and recreational environments with physical activity. METHODS: Randomly selected adults (n = 102, 52% female, 81% white, mean age = 48 years) completed a survey of eight neighborhood design variables, convenient recreational facilities, and availability of home equipment. Physical activity was measured by self-report and 7 days of accelerometer monitoring. RESULTS: Residential density and an overall environment index were significantly related to both vigorous-intensity self-reported (r = .35 and .28, respectively) and objectively measured physical activity (r = .39 and .23, respectively). Home equipment was correlated with self-reported total (r = .34) and vigorous leisure-time physical activity (r = .27). The vigorous and total activity accelerometer measures were correlated with street connectivity (r = .25 and .21, respectively). DISCUSSION: Few self-reported neighborhood design factors and recreational environment variables were correlated with physical activity, and some findings were unexpected.
