目的：本研究的目的是检查公共政策（菜单标签）对饮食病理高风险人群的影响。具体来说，这项研究寻找与进食障碍水平相关的任何不良影响。研究设计：这项研究采用了前后干预设计。基线收集工作于2012年10月进行。在2012年11月随访前一周，大学食堂几乎所有菜单项旁边都显示了卡路里标签。标签保持在整个follow-up.Methods的持续时间：参与者是女大学生（N = 299）。在基线和后续行动中，一项调查评估进食障碍水平（饮食态度测试-26），情绪状态，频率从事不健康的体重相关的行为，和calorie consumption.Results：广义估计方程被用来测试随着时间的推移，在响应卡路里标签的负面结果的变化。从基线（平均值= 660.5 kcal）到随访（平均值= 600.5 kcal; P = 0.104），卡路里消耗没有显著降低。在身体形象满意度等情绪状态方面没有变化（P = 0.447）、焦虑（P = 0.595）、积极情感（P = 0.966）、消极情感（P = 0.576）和不健康的体重相关行为，如暴饮暴食（P = 0.268）、过度锻炼（P = 0.847）或限制卡路里（P = 0.504）。此外，有没有进食障碍水平和time.Conclusions之间的相互作用：总体而言，没有不良后果，发现这个高危人群。卡路里标签对饮食失调程度较高的人没有产生不同的影响。未来的研究应该集中在检查卡路里标签对临床饮食失调患者的影响。(C)2015年，皇家公共卫生学会。由爱思唯尔有限公司出版。保留所有权利。
Objectives: The aim of the study was to examine the effect of a public policy (menu labelling) on those at high-risk for eating pathologies. Specifically, the study looked for any adverse effects related to eating disturbance level.Study design: The study employed a pre-post intervention design. Baseline collection took place in October 2012. One week prior to follow-up in November 2012, calorie labels were displayed next to virtually all menu items in a University cafeteria. Labels remained throughout the entire duration of follow-up.Methods: Participants were female undergraduates (N = 299). At baseline and follow-up, a survey assessed eating disturbance level (Eating Attitudes Test-26), emotional state, frequency of engaging in unhealthy weight-related behaviours, and calorie consumption.Results: Generalized estimating equations were used to test changes in negative outcomes over time in response to calorie labels. Calorie consumption did not significantly decrease from baseline (mean = 660.5 kcal) to follow-up (mean = 600.5 kcal; P = 0.104). There were no changes in emotional states such as body image satisfaction (P = 0.447), anxiety (P = 0.595), positive affect (P = 0.966), negative affect (P = 0.576), and unhealthy weight-related behaviours such as binging (P = 0.268), exercising excessively (P = 0.847), or restricting calories (P = 0.504). Additionally, there were no interactions between eating disturbance level and time.Conclusions: Overall, no adverse outcomes were found for this at-risk population. Calorie labels did not differentially affect those with higher levels of eating disturbance. Future research should focus on examining the impact of calorie labels among those with clinical eating disorders. (C) 2015 The Royal Society for Public Health. Published by Elsevier Ltd.
