在线杂货店提供了机会，鼓励更健康的食品选择的时刻，消费者把他们选择的产品在他们的篮子。本研究评估了交换报价，营养评分标签，和描述性规范信息的营养分析（NP）分数的食物选择在网上食品篮的效果。此外，还探讨了这些干预措施是否使消费者更有动力和更容易选择更健康的食品，以及消费者的健康利益是否会缓和潜在的影响。在模拟在线超市中通过随机对照试验（RCT）对假设进行了检验。荷兰参与者（n = 550）选择了他们的首选产品的六种产品选项的四个不同的类别（早餐麦片，饼干，比萨饼，和牛奶什锦早餐酒吧）。参与者被随机分配到8个组之一，基于2（营养评分：存在，不存在）X 2（交换报价：存在，不存在）X 2（标准信息：存在，不存在）的干预措施。主要结果是产品选择的NP综合评分的差异，评分越低代表产品越健康。互换要约（B = − 9.58，95% CI：[− 12.026; − 7.132]，R2 = 0.098）和营养评分标签（B = − 3.28，95% CI：[− 5.724;- .829]，R2 = 0.013）与对照条件相比，显著改善了组合NP评分（NP评分M = 18.03，SD = 14.02），而正常信息没有显著影响（B =-1.378，95% CI [-3.825; 1.070]，N2 = 0.002）。没有证据表明干预措施使消费者更有动力或更容易选择更健康的食物，但情境动机显著影响了交换报价（B =-3.40，p < .001）和营养评分（B =-3.25，p < .001）的食物选择的健康评分。消费者健康兴趣仅显著缓和营养评分对识别健康食品选择的容易性的影响（B = .23，p = .04）。交换报价和营养评分标签是有效的，在网上商店环境中提高健康的购买行为。本研究于2021年2月9日在ISRCTN数据库中回顾性注册（ISRCTN 80519674）。在线版本包含补充材料，可通过10.1186/s12966-021-01222-8获得。
Online grocery stores offer opportunities to encourage healthier food choices at the moment that consumers place a product of their choice in their basket. This study assessed the effect of a swap offer, Nutri-Score labeling, and a descriptive norm message on the nutrient profiling (NP) score of food choices in an online food basket. Additionally explored was whether these interventions made it more motivating and easier for consumers to select healthier foods and whether potential effects were moderated by consumer health interest. Hypotheses were tested with a randomized controlled trial (RCT) in a simulated online supermarket. Dutch participants (n = 550) chose their preferred product out of six product options for four different categories (breakfast cereals, crackers, pizza, and muesli bars). Participants were randomly allocated to one of eight groups based on the interventions in a 2 (Nutri-Score: present, not present) X 2 (swap offer: present, not present) X 2 (norm message: present, not present) between subject design. The primary outcome was the difference in combined NP score of product choices, for which a lower score represented a healthier product. Swap offer (B = − 9.58, 95% CI: [− 12.026; − 7.132], Ƞ2 = 0.098) and Nutri-Score labeling (B = − 3.28, 95% CI: [− 5.724; −.829], Ƞ2 = 0.013) significantly improved the combined NP score compared to the control condition (NP score M = 18.03, SD = 14.02), whereas a norm message did not have a significant effect (B = − 1.378, 95% CI [− 3.825; 1.070], Ƞ2 = 0.002). No evidence was found that interventions made it more motivating or easier for consumers to select healthier food, but situational motivation significantly influenced the healthiness score of food choices for both swap offer (b = − 3.40, p < .001) and Nutri-Score (b = − 3.25, p < .001). Consumer health interest only significantly moderated the influence of Nutri-Score on ease of identifying the healthy food option (b = .23, p = .04). Swap offer and Nutri-Score labeling were effective in enhancing healthy purchase behavior in the online store environment. This study was retrospectively registered in the ISRCTN database on 02-09-2021 (ISRCTN80519674). The online version contains supplementary material available at 10.1186/s12966-021-01222-8.
