To evaluate the efficacy and consumer preferences of calorie labeling on menus.
Between-group experiment. Participants were randomized to view menu items according to 1 of 4 experimental conditions: no calorie information, calorie-only information, calorie plus health statement (HS), and calorie plus the Physical Activity Scale. Participants selected a snack and then rated menus from all conditions on the level of understanding and perceived effectiveness.
University of Waterloo, Canada.
A total of 213 undergraduate university students recruited from classrooms.
The calorie amount of menu selection and ratings of understandability and perceived effectiveness.
Linear regression models and chi-square tests.
Participants who selected items from menus without calorie information selected snacks with higher calorie amounts than participants in the calorie-only condition (P = .002) and the calorie plus HS condition (P = .001). The calorie plus HS menu was perceived as most understandable and the calorie plus calorie plus Physical Activity Scale menu was perceived as most effective in helping to promote healthy eating.
Calorie labeling on menus may assist consumers in making healthier choices, with consumer preference for menus that include contextual health statements.
评估菜单上卡路里标注的功效和消费者偏好。
分组实验。参与者被随机分配到以下 4 种实验条件之一查看菜单项目：无卡路里信息、仅卡路里信息、卡路里加健康声明（HS）以及卡路里加体力活动量表。参与者选择一种小吃，然后对所有条件下的菜单进行理解程度和感知效果的评分。
加拿大滑铁卢大学。
从教室里招募的 213 名本科大学生。
菜单选择的卡路里量以及理解程度和感知效果的评分。
线性回归模型和卡方检验。
与仅卡路里条件（P =.002）和卡路里加 HS 条件（P =.001）相比，不查看卡路里信息的参与者从菜单中选择的小吃卡路里含量更高。卡路里加 HS 菜单被认为最容易理解，而卡路里加体力活动量表菜单被认为在帮助促进健康饮食方面最有效。
菜单上的卡路里标注可能有助于消费者做出更健康的选择，消费者更喜欢包含上下文健康声明的菜单。
