Produce sold as plastic-wrapped packs of two to four individual items (i.e., produce micro-packs) that are low cost and placed at checkout may appeal to shoppers with budget constraints and provide a second chance to purchase items available elsewhere in the store. This study examined the impact of an intervention that placed produce micro-packs at checkout and promoted them in grocery stores across New Mexico, USA.
This quasi-experimental study placed produce micro-packs at checkout end-caps in thirteen stores (group 1), with eight stores serving as controls (group 2) from 1 July 2019 through 31 January 2020 (first phase). The intervention was extended to group 2 stores from 1 February 2020 through 30 June 2020 (second phase). Cashiers were directed to upsell the micro-packs to Special Supplemental Nutrition Program for Women, Infants, and Children recipients who had unspent cash value benefits for produce purchases.
Twenty-one grocery stores across New Mexico.
Twenty-one produce items sold as micro-packs in stores from July 2019 through June 2020.
A random effects model showed that the daily sales of micro-packs increased by 47 % during each intervention period. Group 2 stores had lower sales than group 1 stores during the first phase of the intervention. Once extended to group 2 stores, sales of micro-packs in those stores increased and sales in group 1 stores continued at the higher level.
Placing produce micro-packs at checkout may increase produce sales and support health promotion efforts by public and private stakeholders.
以两到四个单品的塑料包装形式出售的农产品（即生产微型包装）成本较低，放置在收银台可能会吸引预算有限的购物者，并为购买商店其他地方有售商品提供第二次机会。本研究考察了一项干预措施的影响，该措施将农产品微型包装放置在收银台，并在美国新墨西哥州的杂货店中对其进行推广。
这项准实验研究于2019年7月1日至2020年1月31日（第一阶段），在13家商店的收银台端架上放置农产品微型包装（第1组），8家商店作为对照（第2组）。干预措施于2020年2月1日至2020年6月30日扩展到第2组商店（第二阶段）。收银员被指示向有未使用的农产品购买现金价值福利的妇女、婴儿和儿童特别补充营养计划受益人推销微型包装。
新墨西哥州的21家杂货店。
2019年7月至2020年6月在商店中以微型包装形式出售的21种农产品。
随机效应模型显示，在每个干预期间，微型包装的日销售额增长了47%。在干预的第一阶段，第2组商店的销售额低于第1组商店。一旦扩展到第2组商店，这些商店中微型包装的销售额增加，而第1组商店的销售额继续保持在较高水平。
将农产品微型包装放置在收银台可能会增加农产品销售额，并支持公共和私人利益相关者的健康促进努力。
