To evaluate evidence regarding grocery store tours as an effective nutrition education medium for improving nutrition knowledge and food-related behaviors.
A systematic literature review of studies published from 1984 to 2015 concerning grocery store (or supermarket) tours and impact on nutrition knowledge and behaviors. Three investigators independently reviewed articles, extracted details, and assessed the quality of each study.
Of 307 citations identified, 8 were reviewed and 6 were of neutral quality. Increases in nutrition knowledge were reported in 4 studies, as evaluated by investigator-designed quizzes, with short intervals between tours and assessments. Six programs assessed behavior change using subjective reports or objective purchasing behavior measures; 2 studies did not perform statistical analyses. The 6 studies that reported positive health-related outcomes had varying topics, tour lengths, and target audiences.
Grocery store tours are increasingly used as an avenue for nutrition education to improve knowledge and/or alter food selection behaviors and may result in positive outcomes, but it is unknown whether these outcomes persist for longer than 3 months after the tour and whether there are common attributes of effective grocery store tours. More rigorous studies with uniform methodology in study design and outcome measures are needed to confirm the effectiveness of supermarket tours.
评估杂货店参观作为一种有效营养教育媒介，用于提高营养知识和与食物相关行为的证据。
对1984年至2015年发表的有关杂货店（或超市）参观及其对营养知识和行为影响的研究进行系统文献综述。三名研究人员独立审查文章、提取细节并评估每项研究的质量。
在识别出的307篇文献中，8篇被审查，6篇质量为中等。4项研究报告了营养知识的增加，这是通过研究人员设计的测验评估的，参观和评估之间的间隔较短。6个项目使用主观报告或客观购买行为测量来评估行为变化；2项研究未进行统计分析。报告了与健康相关积极结果的6项研究有不同的主题、参观时长和目标受众。
杂货店参观越来越多地被用作营养教育的途径，以提高知识和/或改变食物选择行为，并且可能会产生积极结果，但尚不清楚这些结果在参观后是否能持续超过3个月，以及有效的杂货店参观是否有共同特征。需要在研究设计和结果测量方面采用统一方法进行更严格的研究，以证实超市参观的有效性。
