简介：智能午餐运动旨在为学校提供简单、低成本的解决方案，鼓励学生在学校选择更健康的食物。本研究的目的是评估促进水果的智能午餐干预措施对中学生选择和消费水果的影响。设计：2014年2月至4月在纽约州北部使用前测/后测对照组设计进行了为期9周的集群RCT。招募了10所中学（5-8年级），并随机分为水果干预组（n = 4），蔬菜干预组（n = 3）或对照组（n = 3）。本文只关注水果干预组和对照组。干预：水果干预组在6周的时间里改变了他们午餐室里水果的便利性、可见性和吸引力。对照组不做任何改变，干预后提供Smarter Lunchrooms培训。主要观察指标：2014年2月至4月收集选择和盘子浪费数据，并在2014-2015年进行分析。计算食物的平均选择、浪费和消耗量，并使用t检验统计和差异分析来分析处理组和对照组之间的统计差异。结果：水果选择总体增加了36%（p < 0.001），水果消耗总体增加了23%（p < 0.017）。蔬菜的选择和消费以及白色牛奶的选择也在治疗学校中显著增加（p < 0.001），尽管总体上并不显著。结论：水果干预增加了水果的选择和消费，并增加了治疗学校中蔬菜的选择和消费以及白色牛奶的选择。这些发现提供了证据支持在中学使用水果促进智能午餐技术，以增加健康食品的选择和消费。(C)2017由Elsevier Inc.出版美国预防医学杂志（American Journal of Preventive Medicine）
Introduction: The Smarter Lunchrooms Movement was developed to provide schools with simple, low-cost solutions to encourage students to make healthier food choices at school. The objective of this study was to evaluate the impact of fruit-promoting Smarter Lunchroom interventions on middle school students' selection and consumption of fruits.Design: A 9-week cluster RCT was conducted using a pre-test/post-test control group design in upstate New York in February-April 2014.Setting/participants: Ten middle schools (Grades 5-8) were recruited and randomized into a fruit intervention (n = 4), vegetable intervention (n = 3), or control group (n = 3). This article focuses only on the fruit intervention and control groups.Intervention: The fruit intervention group made changes to the convenience, visibility, and attractiveness of fruit in their lunchrooms for a period of 6 weeks. The control group made no changes, and were offered Smarter Lunchrooms training post-intervention.Main outcome measures: Selection and plate waste data were collected from February to April 2014, and analyzed in 2014-2015. Average selection, waste, and consumption of food items were computed, and the statistical differences between treatment and control groups were analyzed using t-test statistics and difference-in-difference analysis.Results: Fruit selection increased overall by 36% (p < 0.001), and fruit consumption increased overall by 23% (p < 0.017). Vegetable selection and consumption and white milk selection also increased significantly in the treatment schools (p < 0.001), though were not significant overall.Conclusions: The fruit intervention increased the selection and consumption of fruits overall, and increased the selection and consumption of vegetables and the selection of white milk in treatment schools. These findings provide evidence supporting the use of fruit-promoting Smarter Lunchrooms techniques in middle schools to increase the selection and consumption of healthy food items.
