About this study

Official title: A Randomized Crossover Trial Evaluating the Cardiometabolic Impact of a Produce Prescription Program in Patients With Type 2 Diabetes and Food Insecurity

This study is testing whether providing monthly vouchers to buy fruits and vegetables can help improve blood sugar control in adults with type 2 diabetes. People receiving care at WVU clinics who recently had an HbA1c level above 8% will be invited to participate in the study. Those who are interested will speak with a study coordinator, be screened for eligibility, and, if eligible, will provide written consent to join the study. Participants will be randomly assigned to one of two groups. One group will receive $100 per month in produce-only grocery vouchers and standardized dietary education for 5 months, followed by 5 months of usual diabetes care. The second group will receive usual diabetes care first for 5 months, followed by 5 months of produce-only grocery vouchers and standardized dietary education. This crossover design allows all participants to experience both approaches during the study. Researchers will measure changes in blood sugar (HbA1c) as the main outcome. Other outcomes include blood pressure, cholesterol levels, body weight, diet quality, food security, anxiety symptoms, depressive symptoms, and physical activity. These will be assessed through lab tests, clinic measurements, and surveys at certain time points during the 10 month study period. The study team will also track how often participants use the vouchers and any challenges they face. The risks of participating are expected to be minimal and similar to routine diabetes care. The total study duration, including enrollment, participation, and analysis, is expected to be about 18 months.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Produce Gift Card and Dietary EducationBehavioural

    Participants receive $100 per month in Walmart gift cards restricted to the purchase of fruits and vegetables. Gift cards are provided monthly during the intervention period and usage is tracked using participant-specific access codes. Participants also receive standardized dietary education consistent with current clinical guidelines, delivered by study personnel during the intervention period only.

  • Usual CareOther

    Participants receive standard clinical care for management of type 2 diabetes. No study-provided produce vouchers or study-provided dietary education are provided during this period.

Model description
This is a randomized crossover study in which participants are assigned to one of two sequences: a produce prescription intervention consisting of fruit and vegetable vouchers plus standardized dietary education for 5 months followed by usual care for 5 months, or usual care for 5 months followed by the produce prescription intervention for 5 months. Outcomes are assessed at baseline, 5 months, and 10 months. Analyses compare outcomes during intervention and usual care periods while accounting for treatment sequence and study period.

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Hemoglobin A1c from Baseline to 5 Months (time frame: Baseline and 5 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
