The intervention sought to increase fruit and vegetable availability, variety, and convenience through placement, promotion, and pricing of healthy foods and beverages in tribal convenience stores.

Diabetes and Obesity Associated with Poor Food Environments in American Indian Communities: the Tribal Health and Resilience in Vulnerable Environments (THRIVE) Study.

Background: American Indians (AIs) have significantly higher rates of diet-related chronic diseases than other racial/ethnic groups, and many live in environments with limited access to healthy food.

Objective: As part of the Tribal Resilience in Vulnerable Environments (THRIVE) study, we examined the relations between the perceived food environment, utilization of food retailers, fruit and vegetable intake, and chronic diseases, including obesity, hypertension, and type 2 diabetes among AI adults.

Methods: Through a community-based participatory research partnership, we surveyed a cross-sectional sample of 513 AIs living within the Chickasaw Nation and the Choctaw Nation of Oklahoma.
