目的：在这项研究中，我们研究了针对食品服务人员的干预措施对学校食堂智慧餐厅依从性的影响。方法：这项研究采用了准实验设计，在弗吉尼亚州的一个学区进行，主要服务对象是非裔美国儿童，所有儿童都有资格获得免费餐食。 2014-15 年，来自 43 所学校的食堂经理（N = 38）接受了行为经济学和选择架构原则的培训（并负责培训员工），该选择架构旨在通过改变食堂环境来增强学生的食物选择。 2015-16 年开展了加强培训。食堂人员完成干预后调查；训练有素的评估员对自助餐厅环境进行了客观评级，评估基线、干预后和一年随访中对“智慧餐厅”原则的遵守情况。还检查了销售数据。结果：自助餐厅人员对培训感到满意（3.91 [共 5]+/- 0.70），并对自己做出改变的能力充满信心（4.18 +/- 0.52）。干预后对智慧餐厅原则的总体遵守率提高了 6.47%，后续提高了 6.93%（p = .001；部分 eta(2) = .21-.24），干预后含糖饮料销量相应下降 (p = .001)。结论：这种以培训食堂人员为重点的环境层面干预措施与提高对“智慧餐厅”原则的遵守程度有关，并持续了两年多。未来的研究应该通过严格设计的试验来调查这种干预措施对学生饮食行为的影响。
Objective: In this study, we examined the impact of an intervention targeting food service personnel on Smarter Lunchroom adherence in school cafeterias. Methods: This study used a quasi-experimental design, conducted in a Virginia school district serving predominantly African-American children, all eligible for free meals. In 2014-15, cafeteria managers (N = 38) from 43 schools were trained (and tasked with training their staff) on principles of behavioral economics and choice architecture designed to enhance students' food selections via modifications to the cafeteria environment. Booster trainings were conducted in 2015-16. Cafeteria personnel completed post-intervention surveys; trained raters conducted objective cafeteria environment ratings, assessing adherence with Smarter Lunchroom principles, at baseline, post-intervention, and one-year follow-up. Sales data also were examined. Results: Cafeteria personnel were satisfied (3.91 [of 5]+/- 0.70) with the training and confident (4.18 +/- 0.52) in their ability to make changes. Overall adherence to Smarter Lunchroom principles increased 6.47% at post-intervention and 6.93% at follow-up (p = .001; partial eta(2) = .21-.24), with a corresponding decrease in sugared-beverage sales at post-intervention (p = .001). Conclusions: This environmental-level intervention focused on training cafeteria personnel was associated with increased adherence to Smarter Lunchroom principles, sustained over 2 years. Future research should investigate the impact of this intervention on students' dietary behaviors in a rigorously designed trial.
