Native-Controlling Hypertension and Risk through Technology RP1: Chickasaw Healthy Eating Environments Research Study (Native-CHART RP1 / CHEERS)

Status: Current

Grant Start: 08/01/2016

Grant End: 02/28/2022

Diet-related chronic diseases, such as hypertension and obesity, are prevalent in Native American communities where poor food environments are prominent and healthy food access is limited. The Chickasaw Healthy Eating Environments Research Study (CHEERS), Research Project 1 of Native-Controlling Hypertension and Risk through Technology, is an NIH-funded study aimed to improve body mass index and blood pressure control among Native American adults with uncontrolled hypertension. This multi-level randomized trial, guided by a community-based participatory research orientation, was co-created by Tribal and university partners and is implemented within the Chickasaw Nation of Oklahoma. In partnership with Feed the Children, we created hypertension-specific food boxes that contain Dietary Approaches to Stop Hypertension (DASH) diet foods, coupons for purchasing vegetables and fruits, educational materials, and heart-healthy recipes for supporting healthy eating. Food boxes are packed and shipped monthly to intervention participants with a 30-day supply of one fruit serving/day, one vegetable serving/day, one serving of unsalted nuts or seeds/day, one serving of beans or lentils/day, and two servings of fatty fish/week. The study intervenes at the environmental level by improving healthy food access and at the policy level by assessing Tribal leaders’ readiness to implement CHEERS across the Tribal nation.
