Disadvantaged rural youth may be especially at risk for obesity and poorer health due to physical inactivity. Research suggests that extracurricular school programs can increase physical activity for this population. This study sought to determine whether local differences existed in the availability of supportive environments for extracurricular physical activity in North Carolina middle schools. Multiple data sources, including a self-administered questionnaire to personnel at 325 schools were integrated. Multilevel models were estimated using a composite index for supportive environments as the dependent variable and school compositional factors, economic resources, and community social factors as explanatory variables. Study findings suggested adolescents living in socioeconomically deprived rural areas had fewer environmental resources for extracurricular physical activity. Rural schools in poor areas of the state with high racial heterogeneity demonstrated the lowest environmental support. Reduced availability of supportive school environments may be one factor contributing to physical inactivity in the state.
