Tribal Health and Resilience in Vulnerable Environments

Study Overview
=================
Brief Summary
-----------------
The THRIVE study is a healthy retail intervention that improves the food environments in tribally owned and operated convenience stores in the Chickasaw Nation and Choctaw Nation of Oklahoma.

Detailed Description
-----------------
The THRIVE study is a cluster randomized trial, using a community-based participatory research approach, of healthy makeovers in eight convenience stores owned and operated by the Chickasaw Nation and Choctaw Nation of Oklahoma. The study will test the ability of tribal nations to increase fruit and vegetable purchasing and consumption among tribal members through environmental and policy approaches. Investigators hypothesize that tribal members exposed to the highest doses of the intervention (i.e. those who visit the intervention convenience stores the most) will increase their fruit and vegetable intake. Individual-level changes in fruit and vegetable intake will be measured via a survey administered to a cohort of 1600 American Indian shoppers before and after the intervention. A multimedia manual, Website, and documentary film will be created as part of the implementation of THRIVE to engage tribal citizens, enhance local knowledge, and guide other tribes to improve their food and physical activity environments.
