American Indian children endure disproportionately high obesity rates, yet few academic institutions have cultivated sustainable relationships with American Indian communities committed to improving food access. This project will: (1) apply community-based participatory research methodologies to build partnerships with the North Carolina Commission of Indian Affairs and North Carolina tribal communities to gain an understanding of how environmental and policy factors influence access to healthy foods; (2) examine existing data sources to identify and map the type and location of food outlets within tribal communities; (3) assess agreement among the existing food outlet data sources and validate existing data using field-based observations; and (4) conduct legal and policy analyses of regulations and rules relating to healthy food access in order to guide solution-oriented strategies and develop a toolkit for improving access to healthy foods within each of the tribal communities.
