Using data from the 2007 National Survey of Children’s Health (NSCH),the purpose of this study is to examine the relationship between youth physical activity levels,weight status,and neighborhood context,using multiple measures of perceived neighborhood social and physical condition.We hypothesized significant relationships would exist between constructs for neighborhood context and youth health above individual and family-level demographic characteristics.Identifying a relationship between neighborhood characteristics and cardiovascular health indicators,such as youth physical activity and weight status,may be instrumental in developing innovative public health interventions and policies effective in facilitating improved youth health.
