Calorie labeling at the point-of-purchase in chain restaurants has been shown to reduce energy intake.
To investigate the impact of point-of-purchase calorie information at one rural middle school.
With a community-based participatory research framework a mixed method approach was used to evaluate the impact of point-of-purchase calorie information. Students in grades 6-8, dining at the school cafeteria January and February 2010, participated for 17 school days each month; in January a menu was offered in the usual manner without calorie labels; the same menu was prepared in February with the addition of calorie labels at point-of-purchase. Gross calories served per student were measured each day allowing for matched comparison by menu. In March/April of 2010, 32 students who ate in the cafeteria 3 or more times per week were interviewed regarding their views on menu labeling.
Calorie consumption decreased by an average of 47 calories/day; fat intake reduced by 2.1 grams/day. Five main themes were consistent throughout the interviews.
Point-of-purchase calorie labels can play a role in reducing the number of calories consumed by middle school age children at the lunch. The majority of students interviewed found the calorie labels helped them choose healthier food.
连锁餐厅在购买点标注卡路里已被证明可减少能量摄入。
调查一所农村中学购买点卡路里信息的影响。
采用基于社区的参与性研究框架，运用混合方法评估购买点卡路里信息的影响。2010年1月和2月在学校食堂就餐的6至8年级学生，每月参与17个上学日；1月以常规方式提供菜单，无卡路里标签；2月准备相同菜单，在购买点增加卡路里标签。每天测量每位学生的总卡路里摄入量，以便按菜单进行匹配比较。2010年3月/4月，对每周在食堂就餐3次或更多次的32名学生就其对菜单标签的看法进行了访谈。
卡路里摄入量平均每天减少47卡路里；脂肪摄入量每天减少2.1克。访谈中始终存在五个主要主题。
购买点卡路里标签可在减少中学年龄段儿童午餐时的卡路里摄入量方面发挥作用。大多数受访学生发现卡路里标签有助于他们选择更健康的食物。
