We assessed consumer awareness of menu calorie information at fast-food chains after the introduction of New York City's health code regulation requiring these chains to display food-item calories on menus and menu boards.
At 45 restaurants representing the 15 largest fast-food chains in the city, we conducted cross-sectional surveys 3 months before and 3 months after enforcement began. At both time points, customers were asked if they had seen calorie information and, if so, whether it had affected their purchase. Data were weighted to the number of city locations for each chain.
We collected 1188 surveys pre-enforcement and 1229 surveys postenforcement. Before enforcement, 25% of customers reported seeing calorie information; postenforcement, this figure rose to 64% (P < .001; 38% and 72%, weighted). Among customers who saw calorie information postenforcement, 27% said they used the information, which represents a 2-fold increase in the percentage of customers making calorie-informed choices (10% vs 20%, weighted; P < .001).
Posting calorie information on menu boards increases the number of people who see and use this information. Since enforcement of New York's calorie labeling regulation began, approximately 1 million New York adults have seen calorie information each day.
在纽约市健康法规要求快餐连锁店在菜单和菜单板上显示食品项目卡路里后,评估消费者对快餐连锁店菜单卡路里信息的认知。
在该市 15 家最大快餐连锁店的 45 家餐厅进行横断面调查,在实施前 3 个月和实施后 3 个月进行。在这两个时间点,都询问顾客是否看到了卡路里信息,如果看到了,是否会影响他们的购买。数据根据每个连锁店在城市中的位置数量进行加权。
我们在实施前收集了 1188 份调查,在实施后收集了 1229 份调查。在实施前,25%的顾客报告说看到了卡路里信息;实施后,这一数字上升到 64%(P <.001;未加权分别为 38%和 72%)。在实施后看到卡路里信息的顾客中,有 27%的人表示他们使用了这些信息,这意味着做出卡路里知情选择的顾客比例增加了一倍(未加权分别为 10%和 20%;P <.001)。
在菜单板上发布卡路里信息会增加看到和使用这些信息的人数。自纽约卡路里标签法规实施以来,每天约有 100 万纽约成年人看到卡路里信息。
