This study's purpose was to examine changes in healthy and unhealthy items purchased following the implementation of traffic light and cartoon labelling in a small retail food venue (Café Bay) in a children's hospital in eastern North Carolina. Between October 2015 and March 2016, daily food and beverage sales from Café Bay were obtained during baseline, traffic light labelling, a washout period, cartoon labelling (on healthy foods only) and a final washout period. Pearson chi-squared tests and multiple linear regressions were used to examine effects of labelling strategies, controlling for the holidays. In unadjusted analyses, traffic light labelling was associated with significant decreases in purchases of unhealthy items purchased, while cartoon labelling was associated with increases in unhealthy items purchased. In adjusted linear regression analysis, traffic light labelling was associated with fewer unhealthy purchases and thus may have potential to decrease the amount of unhealthy items purchased in a children's hospital food retail venue.
本研究的目的是考察在北卡罗来纳州东部一家儿童医院的小型零售食品场所（海湾咖啡馆）实施交通灯标签和卡通标签后，所购买的健康和不健康食品的变化情况。在2015年10月至2016年3月期间，获取了海湾咖啡馆在基线期、交通灯标签期、洗脱期、卡通标签期（仅针对健康食品）以及最后一个洗脱期的每日食品和饮料销售数据。使用Pearson卡方检验和多元线性回归来考察标签策略的效果，并对节假日进行了控制。在未经调整的分析中，交通灯标签与不健康食品购买量的显著减少相关，而卡通标签与不健康食品购买量的增加相关。在调整后的线性回归分析中，交通灯标签与较少的不健康食品购买相关，因此可能有潜力减少儿童医院食品零售场所中不健康食品的购买量。
