Abstract
Objective: To evaluate the effects of a supermarket meal bundling and electronic reminder intervention on food choices of families with children. Design: Quasi-experimental (meal bundling) and randomized, controlled trial (electronic reminders). Setting: Large supermarket in Maine during 40-week baseline and 16-week intervention periods in 2015–2016. Participants: English-speaking adults living with at least 1 child aged ≤18 years (n = 300) with 25% of households participating in the Supplemental Nutrition Assistance Program. Intervention(s): (1) Four bundles of ingredients needed to make 8 low-cost healthful meals were promoted in the store through displays and point-of-purchase messaging for 4 weeks each; (2) weekly electronic messages based on principles from behavioral psychology were sent to study participants reminding them to look for meal bundles in the store. Main Outcome Measures: (1) Difference in storewide sales and individual purchases of bundled items (measured using supermarket loyalty card data) from baseline to intervention in intervention vs control groups. Analysis: Regressions controlling for total food spending and accounting for repeated measures. Results: There were no differences in spending on bundled items resulting from the meal bundling intervention or the electronic reminders. Conclusions and Implications: Overall, there was little impact of healthful meal bundles and electronic reminders on storewide sales or purchases of promoted items in a large supermarket.
