Ripe for Revival: Outcomes Evaluation of a Mobile Produce Market With Vouchers
What this study is about
Increasing access to healthy foods is crucial to combating chronic disease in rural communities. The Ripe for Revival mobile market, a non-profit eastern NC-based mobile market, seeks to improve healthy food access among those at greatest risk of food insecurity and poor health. By implementing vouchers at the mobile market, this study will help make healthy food affordable and accessible.
View original scientific description
Increasing access to healthy foods is crucial to combating chronic disease in rural communities. The Ripe for Revival mobile market, a non-profit eastern NC-based mobile market, seeks to improve healthy food access among those at greatest risk of food insecurity and poor health. By implementing vouchers at the mobile market, this study will help make healthy food affordable and accessible. This project is poised to improve diet and health among rural residents in eight counties and promote sustainable local food systems in North Carolina.
Interventions
BEHAVIORAL
Mobile Market Voucher Outcomes Study
Voucher participants will be referred by Extension professionals who serve lower-resourced individuals during routine programs (i.e., NC Extension programs such as Expanded Food and Nutrition Education Program (EFNEP). After receiving the referrals from Extension professionals, a member of the research team will contact the referred participant to provide a $20 monthly voucher each month for three months for use at the mobile market. Trained researchers will collect data at baseline (when a voucher is issued), at \~4 weeks (4-6 weeks, 2nd voucher), 8 weeks (8-10 weeks, 3rd voucher), and 12-16 weeks (post-program) at the NC Cooperative Extension office. FV intake will be measured by skin carotenoid scan. Researchers will obtain height (baseline), weight, and blood pressure at each data collection time point. Survey measures will include the secondary outcomes using adapted versions of validated instruments, with questions on demographics and food and nutrition security status.
Primary outcome measures
Skin Carotenoids
Time frame: Enrollment/baseline (week 0), 4-6 weeks, 8-10 weeks, and at 12-16 weeks
Fruit and vegetable intake measured by skin carotenoids (derived from a validated reflection spectroscopy device, Veggie Meter®
Fruit and vegetable intake
Time frame: Enrollment/baseline (week 0), 4-6 weeks, 8-10 weeks, and at 12-16 weeks
Measured by the National Cancer Institute (NCI) Dietary Screener Questionnaire (DSQ) FV screener. The 10-item NCI DSQ FV screener data are collected through participant survey responses. Responses will be converted to daily cup-equivalent estimates using the NCI research team-developed DSQ scoring algorithms, based on age, sex, portion-size estimates, and regression coefficient data.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
