Associations between body mass index, physical activity and the built environment in disadvantaged, minority neighborhoods: Predictive validity of GigaPan® imagery.

•Participants living in disadvantaged, mostly African American neighborhoods supportive of walking and cycling had lower BMI.•Participants were less likely to walk in environments with more recreation land use but less housing.•Environmental exposures were reliably estimated from audits of high-resolution GigaPan® images.•The findings suggest that GigaPan® should be considered for future studies of the built environment and health.•Built environment changes in low-income, mostly African American communities that promote active transport may improve health.
