本文探讨了预先订购和预先订购与行为轻推对选择水果，蔬菜和低脂牛奶的国家学校午餐计划（NSLP）的参与者在佛罗里达学校的影响。在收集了两周的基线数据后，四年级和五年级的学生被随机分配到两个治疗组中的一个：第一个治疗组使用独特的软件程序在线预订午餐;第二个治疗组在预订时接受基于美国农业部（USDA）MyPlate建议的行为推动。四年级和七年级的学生作为对照组，继续通过正常的午餐线获得午餐。使用差中差回归分析，我们发现，相对于对照组的学生，第一治疗组的学生在研究的预订购干预阶段选择了更多的水果，蔬菜和低脂牛奶，分别为27.7%，15.8%和16.3%，而第二治疗组的学生选择了更多的水果（51.4%）、蔬菜（29.7%）和低脂牛奶（37.3%）高于对照组。此外，我们发现，除了预先订购的效果外，轻推还具有统计学上显著的积极影响;在预先订购时接受MyPlate轻推的学生比没有轻推的学生选择了更多的水果，蔬菜和低脂牛奶。(C)© 2016 Elsevier B.

This paper examines the effects of pre-ordering and pre-ordering with behavioral nudges on the selection of fruits, vegetables, and low-fat milk by National School Lunch Program (NSLP) participants in a Florida school. After collecting two weeks of baseline data, students in grades four and five were randomly assigned to one of two treatment groups: the first treatment group pre-ordered their lunches online using a unique software program; the second treatment group received behavioral nudges based on United States Department of Agriculture (USDA) MyPlate recommendations while pre-ordering. Student in grades four and seven served as the control group and continued to obtain their lunches through the normal lunch line. Using difference-in-difference regression analysis, we find that students in the first treatment group selected significantly more fruits, vegetables, and low-fat milk during the pre-ordering intervention phase of the study relative to students in the control group, 27.7%, 15.8%, and 16.3%, respectively, while students in the second treatment group selected significantly more fruits (51.4%), vegetables (29.7%) and low-fat milk (37.3%) than students in the control group. In addition, we find the nudge had a statistically significant positive effect in addition to the effect of pre-ordering; students who received the MyPlate nudge while pre-ordering selected statistically significantly more fruits, vegetables, and low-fat milk than students who pre-ordered without nudging.
