Plain English Summary
Background and study aims
Healthy eating can be difficult for people who live in poor, geographically isolated regions of the United States. In particular, people who live in Appalachia often experience food insecurity (i.e., their access to adequate food is limited by a lack of money and other resources at times during the year) and lack of access to healthy foods. This pilot study evaluates the effectiveness of motivational interviewing in helping individuals who live in these austere regions improve their diets in the context of limited resources and healthy food availability.
Who can participate?
People who live in one of six rural Kentucky food desert counties (a food desert is an urban area in which it is difficult to buy affordable or good-quality fresh food).
What does the study involve?
Participants in three of the counties will receive an education/skills intervention paired with a form of coaching called motivational interviewing conducted by a trained registered nurse. Three similar counties that do not border any of the intervention counties are serving as controls (these counties receive the same nutrition education/skills intervention without motivational interviewing). All participants will receive cookbooks, cooking classes, food preparation tools and prepared food dishes to take home to their families. We will measure the impact of motivational interviewing on fresh fruit and vegetable consumption, saturated fat consumption and number of meals cooked at home.
What are the possible benefits and risks of participating?
People in the study will learn how to cook healthy meals for their families. They will also learn how to read food labels, make recipe substitutions and become more aware of the healthy foods available in their community. There are no known risks to participating in this study.
Where is the study run from?
University of Kentucky College of Nursing (USA).
When is the study starting and how long is it expected to run for?
From January 2014 to March 2016.
Who is funding the study?
National Institute of Nursing Research (USA).
Who is the main contact?
Dr Frances Hardin-Fanning
The impact of motivational interviewing during a nutrition education and skills intervention in Central Appalachia
Primary aim: To develop and test the effectiveness of a culturally appropriate, individualized dietary behavior change intervention that includes motivational interviewing aimed at increasing consumption of foods known to decrease CVD risk.
Hypothesis: Intervention group participants who receive motivational interviewing sessions will exhibit a greater increase in the consumption of healthy foods compared to participants in the control group.
Secondary aim: To determine whether health literacy, financial status and/or risk of food insecurity moderate the effects of the intervention on consumption of CVD risk-reducing foods.

Adherence to a healthy diet
Adherence to a healthy diet is difficult in rural Central Appalachian food deserts and strategies to improve dietary habits in this region must consider the impact of austere environment and cultural food norms. This longitudinal pilot study is being conducted in six eastern Kentucky rural Appalachian food desert counties with similar demographics to determine the impact of motivational interviewing on consumption of foods associated with better health outcomes.
The education/skills intervention paired with motivational interviewing is being delivered in three contiguous rural Kentucky food desert counties. Three similar counties that do not border any of the intervention counties are serving as controls (these counties receive the same nutrition education/skills intervention without motivational interviewing). Counties were determined in collaboration with the UK College of Agriculture Cooperative Extension faculty. All participants in the intervention and control groups received an AHA cookbook, cooking classes taught by Family and Consumer Science agents at their cooperative extension office, and food preparation tools along with instructions on how to read nutrition labels. Intervention participants are contacted monthly by a trained registered nurse who assists them in developing an individualized plan of successful behavior change and they are receiving monitoring and feedback, using MI techniques.
Primary outcome measures
