Little is known about relationships between attributes of land use plans and sociodemographic variations in physical activity (PA). This study evaluates associations between policy-relevant plan attributes, sociodemographic factors, and PA in North Carolina. Results suggest that land use plans that included non-automobile transportation improvements and more comprehensive policies to guide development were positively associated with both leisure and transportation-related PA. However, residents of counties with lower-income levels and higher proportions of non-white residents were less likely to have attributes supportive of PA included in their plans. Implications for transdisciplinary collaboration with respect to reducing health disparities are discussed.
