About this trial

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 without stigma. This project is poised to improve diet and health among rural residents in eight counties and promote sustainable local food systems in North Carolina.

Treatments tested in this trial

  • 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 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.

Trial outcomes

Primary outcomes

1

Skin Carotenoids

Fruit and vegetable intake measured by skin carotenoids (derived from a validated reflection spectroscopy device, Veggie Meter®

Time frame
Enrollment/baseline (week 0), 4-6 weeks, 8-10 weeks, and at 12-16 weeks
2

Fruit and vegetable intake

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.

Time frame
Enrollment/baseline (week 0), 4-6 weeks, 8-10 weeks, and at 12-16 weeks

Secondary outcomes

1

Weight/Body Mass Index

Weight/Body Mass Index. Weight measured by an electronic scale SECA 876 as the average of two measures. Height (baseline only) will be measured by a SECA 217 stadiometer.

Time frame
Enrollment/baseline (week 0), 4-6 weeks, 8-10 weeks, and at 12-16 weeks
2

Blood Pressure

Blood pressure measured by noninvasive automated monitor (Omron HEM-907XL, Vernon Hills, IL) with a first measure after seated for 5 minutes and 2 repeat measures at 1-minute intervals.

Time frame
Enrollment/baseline (week 0), 4-6 weeks, 8-10 weeks, and at 12-16 weeks
3

Food Security Status

Food security status, measured by the USDA household 6-item screener. Scores range from 0 to 6, with a lower score (0 to 2) representing food security and a higher score (3 or higher) representing food insecurity

Time frame
Enrollment/baseline (week 0), 4-6 weeks, 8-10 weeks, and at 12-16 weeks
4

Nutrition Security Status

Measured by the Center for Nutrition \& Health Impact 4-item Nutrition Security Screener. The four items within the measure are scored from 0 (participant selects "Always") to 4 (participant selects "Never"). The measure's score is the mean of the responses, with higher scores indicating a greater degree of household nutrition security, or a household that is able to acquire healthful foods without resource limitations or worry. "Low" scores are 2.00 or below

Time frame
Enrollment/baseline (week 0), 4-6 weeks, 8-10 weeks, and at 12-16 weeks
