Make It Fresh, for Less! A Supermarket Meal Bundling and Electronic Reminder Intervention to Promote Healthy Purchases Among Families With Children.

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.
