Brief Summary

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.

Voucher Recipients

EXPERIMENTAL

Voucher participants will be referred by Extension professionals who serve lower-resourced individuals during routine programs

Behavioral: Mobile Market Voucher Outcomes Study

Interventions

Mobile Market Voucher Outcomes Study BEHAVIORAL

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 for three months for use at the mobile market. Trained researchers will collect data at baseline (when a voucher is issued), at \~4 weeks (2nd voucher), 8 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.
