我们对马萨诸塞州波士顿一家医院食堂实施红绿灯食品标签前后的顾客进行了调查，以确定标签对顾客健康食品意识和购买的影响。自助餐厅的食物被识别为红色(不健康)、黄色(不健康)或绿色(健康)。在实施标签之前(N=166)和之后(N=223)对客户进行了访谈。每个受访者都被链接到收银机数据，以确定购买红色、黄色和绿色物品的比例。数据收集于2010年2月至4月。我们比较了基线期间受访的客户和干预期间受访的客户对调查问题的回答以及每笔交易中红色、黄色和绿色物品的平均比例。调查回复率为60%。比较标签干预期间的反应与基线，更多的受访者认为健康/营养是他们购买的一个重要因素(61%对46%，p=0.004)，并报告查看营养信息(33%对15%，p<；0.001)。在干预过程中注意到标签并报告标签影响了他们的购买的受访者比没有注意到标签的受访者更有可能购买更健康的商品(P<；0.001)。红绿灯食品标签促使个人考虑自己的健康，并在购买地点做出更健康的选择。
We surveyed customers in a hospital cafeteria in Boston, Massachusetts before and after implementation of traffic light food labeling to determine the effect of labels on customers’ awareness and purchase of healthy foods. Cafeteria items were identified as red (unhealthy), yellow (less healthy), or green (healthy). Customers were interviewed before (N = 166) and after (N = 223) labeling was implemented. Each respondent was linked to cash register data to determine the proportion of red, yellow, and green items purchased. Data were collected from February–April 2010. We compared responses to survey questions and mean proportion of red, yellow, and green items per transaction between customers interviewed during baseline and customers interviewed during the intervention. Survey response rate was 60%. Comparing responses during labeling intervention to baseline, more respondents identified health/ nutrition as an important factor in their purchase (61% vs. 46%, p = 0.004) and reported looking at nutrition information (33% vs. 15%, p < 0.001). Respondents who noticed labels during the intervention and reported that labels influenced their purchases were more likely to purchase healthier items than respondents who did not notice labels (p < 0.001 for both). Traffic light food labels prompted individuals to consider their health and to make healthier choices at point-of-purchase.
