A pilot randomized controlled trial of a fruit and vegetable prescription program at a federally qualified health center in low income uncontrolled diabetics
Top Things to Know
Participants in the intervention group were provided up to $80 to purchase fresh produce at a farmers' market hosted at their health center over eight weeks, aiming to improve dietary intake among low-income individuals with diabetes.
Although no significant differences were observed between groups at the conclusion of the study, the intervention group experienced a notable decrease in HbA1c levels, from 9.64% to 9.14%. However, there were no significant changes in blood pressure or BMI, indicating that the program's impact may be limited to glycemic control.
Compliance with the program varied significantly among participants. About 28.6% utilized all their produce prescriptions, 58.9% attended the farmers' market at least five times, and 21.4% participated only once. This variation highlights the need for tailored strategies to increase engagement and ensure consistent participation across the target population.
Summary of Conclusion/Findings
The pilot randomized control trial investigated the effects of a 15-week produce prescription program on metabolic health in diabetic patients at a Detroit-based health center. Participants in the intervention group received up to $80 to spend on fresh produce at a farmers' market hosted at their health center. The control group received standard diabetes care and non-produce related gift cards. The primary health outcomes measured were changes in hemoglobin A1C, with secondary outcomes including blood pressure and body mass index (BMI). While the intervention group showed a significant reduction in HbA1c levels, indicating improved blood glucose control, no significant changes were observed in blood pressure or BMI for either group. Compliance varied among participants: 28.6% used all their prescriptions, 58.9% attended the market at least five times, and 21.4% attended only once. This pilot study provides preliminary evidence supporting the potential benefits of produce prescription programs in managing diabetes among low-income populations, with varied levels of participant engagement.
