Dietary interventions may best be delivered at grocery stores, which offer convenience, accessibility, full food inventories, and increasingly, in-store registered dietitians, online shopping, and delivery services. In collaboration with a large supermarket chain, we conducted a multisite, randomized, controlled trial (N = 247) of two individualized, in-person, dietitian-led, purchasing data-guided, education interventions focused on increasing Dietary Approaches to Stop Hypertension (DASH) score (a measure of DASH dietary pattern adherence). At both 3 and 6 months, all study groups had greater DASH adherence. At 3 months, the interventions increased DASH score by 4.7 (95% CI, 0.9, 8.5; p = 0.02), compared with the enhanced control group. In addition, the intervention that included online enhancements (e.g. online shopping, nutrition applications) increased DASH score by 3.8 (95% CI, 0.8, 6.9; p = 0.01) compared to the one without them. This trial demonstrates the efficacy of store-based, dietary interventions as well as modern online shopping tools in increasing DASH adherence. |
