Appalachians Together Restoring the Eating Environment: Improving Healthy Diet in Rural Appalachian Kentucky

Appalachians Together Restoring the Eating Environment (Appal-TREE): Advancing Sustainable CBPR Interventions to Improve Healthy Diet in Rural Appalachian Children

Most of the nation's serious chronic health challenges and causes of death, including diabetes, heart disease, cancer, and obesity, are directly linked to sub-optimal diet. Both poor diets and associated disease are disproportionately common in the Appalachian counties of eastern Kentucky, a region with stark health inequities, including elevated rates of obesity, overweight, and premature mortality. The purpose of this study is to evaluate a multi-component intervention developed through community-based participatory research methods for improving access to healthy foods and enhancing dietary intake in eastern Kentucky. The intervention components evaluated in this study consist of: 1) a school-based campaign to promote water consumption in middle and high schools and 2) a series of group cooking classes for adults.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: School-based water campaign; Students who attend middle and high schools in the intervention counties will receive a school-based water campaign. A sample of students from each school will complete surveys before and after the installation of the water refilling stations to measure beverage consumption, knowledge, attitudes, and self-efficacy.	Behavioral: School-based water campaign; Includes: 1) the installation of filtered water bottle refilling stations, 2) the distribution of reusable water bottles to all students and teachers, and 3) a social marketing campaign to support the increase of water consumption among students.
No Intervention: Comparison schools; A sample of students who attend middle and high schools in the comparison county, which does not receive any intervention components, will complete surveys to measure beverage consumption, knowledge, attitudes, and self-efficacy.
Experimental: Community cooking classes; Adults in the same intervention counties as the school-based water campaign will enroll in group cooking classes. They will complete a baseline and two follow-up surveys to measure changes in fruit and vegetable consumption, attitudes, and self-efficacy.	Behavioral: Community cooking classes; Cooking classes will be delivered to groups of 8-12 adult participants as a series of 8 weekly classes in community venues. The content of each class is driven by topics and themes identified and prioritized by community members, namely cooking healthy on tight budget.
