To evaluate the effects of a supermarket meal bundling and electronic reminder intervention on food choices of families with children.
Quasi-experimental (meal bundling) and randomized, controlled trial (electronic reminders).
Large supermarket in Maine during 40-week baseline and 16-week intervention periods in 2015-2016.
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.
(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.
Regressions controlling for total food spending and accounting for repeated measures.
There were no differences in spending on bundled items resulting from the meal bundling intervention or the electronic reminders.
Overall, there was little impact of healthful meal bundles and electronic reminders on storewide sales or purchases of promoted items in a large supermarket.
评估超市套餐捆绑和电子提醒干预对有孩子家庭食物选择的影响。
准实验（套餐捆绑）和随机对照试验（电子提醒）。
2015-2016 年期间缅因州一家大型超市的 40 周基线和 16 周干预期。
讲英语、至少有 1 名 18 岁以下儿童的成年人（n=300），其中 25%的家庭参加补充营养援助计划。
（1）通过展示和购买点信息宣传，在商店中推广 4 种制作 8 种低成本健康餐所需的食材套餐，每种套餐各持续 4 周；（2）每周根据行为心理学原则向研究参与者发送电子信息，提醒他们在商店中寻找套餐。
（1）干预组与对照组从基线到干预期间，捆绑销售项目的店内总销售额和个人购买额的差异（使用超市会员卡数据衡量）。
控制总食品支出并考虑重复测量的回归分析。
套餐捆绑干预或电子提醒对捆绑销售项目的店内总销售额或购买额没有影响。
总体而言，在一家大型超市中，健康套餐和电子提醒对店内总销售额或推广项目的购买额影响甚微。
