The Supermarket and Web-based Intervention targeting Nutrition (SuperWIN) for cardiovascular risk reduction is a novel, randomized controlled trial aimed at increasing diet quality and decreasing cardiovascular risk. SuperWIN will deliver individualized, nutrition education at the point-of-purchase (POP), either in the aisles of the physical store or via online shopping platforms coupled with other modern software tools.
This study is designed to test whether individualized, POP nutrition education can improve dietary quality. The two interventions to be evaluated in SuperWIN will utilize either an in-store POP education strategy or a combined online/in-store POP education strategy in participants with at least one cardiovascular disease risk factor. The POP education interventions will be enhanced with sophisticated, provider- and participant-facing, food-purchasing metrics, a novel counseling tool that here-to-fore has not been studied in regard to changing food shopping behavior. The primary outcome measure is the Dietary Approaches to Stop Hypertension (DASH) score, a measure of adherence to the DASH dietary pattern. The study is well-powered to test at Day 90: 1) whether any POP education intervention strategy (both intervention arms pooled) improves the DASH score compared to the control arm and 2) whether an improvement in DASH score depends on the POP education strategy utilized. Both POP education strategies will be delivered within a supermarket-based retail clinic and will utilize the aisles and products of the supermarket. The interventions will be delivered by a registered dietitian nutritionist (RDN). The online portion of the combined online/in-store education POP strategy will include online grocery shopping, online recipe resources, a grocery pickup or home delivery service, and a phone application to better select healthy foods. Both strategies will be offered in addition to a "standard of care" medical nutrition therapy session. The DASH dietary pattern has been empirically tested and shown to favorably modify blood pressure, blood cholesterol, insulin sensitivity, and weight status.

Change in Dietary Approaches to Stop Hypertension (DASH) score
The DASH score will be calculated from food group analyses obtained from means of three 24-hour dietary intake recalls at each time-point. This DASH score is a 90-point continuous score used to measure change in overall dietary quality in response to an intervention. Given that the dietary focus of the SuperWIN interventions is the DASH dietary pattern, the DASH score will be used as a measure of adherence to a DASH eating pattern. Higher values indicate greater adherence.
