背景：包装前营养标签可以支持更健康的包装食品购买。澳大利亚采用了一种新颖的健康星星评级（HSR）制度，但这种选择的合法性尚不清楚。目的：确定不同形式的包装前标签对食品购买的健康性和消费者感知的影响。设计图：个人被随机分配到四种不同格式的营养标签HSR，多个交通灯标签（MTL），每日摄入量指南（DIG），建议/警告（WARN）或对照（营养信息面板，NIP）中的一种。参与者在购物时通过使用智能手机应用程序扫描包装食品的条形码来获取营养信息。主要结果是由购买超过四周的包装食品的平均转换营养成分评分定义的健康状况。结果：1578名参与者，平均年龄38岁，84%的女性记录了148，727种可评估食品的购买情况。HSR组购买的平均健康状况不劣于MTL、DIG或WARN（所有p <0.001，非劣效性界值为2%）。与NIP对照组相比，购买HSR、MTL或DIG的平均健康程度没有差异（均p> 0.07），但WARN导致购买更健康的包装食品（平均差异0.87; 95%置信区间0.03至1.72; p = 0.04）。参与者认为HSR比DIG更有用，比MTL或DIG更容易理解（所有p <0.05）。参与者还报告说，与NIP相比，HSR更容易理解，HSR和MTL更有用（所有p <0.03）。结论：这些真实世界的数据与实验结果相一致，并为HSR的政策选择提供支持。建议/警告标签值得进一步探索，因为它们可能是健康食品购买的更强大驱动力。
Background: Front-of-pack nutrition labelling may support healthier packaged food purchases. Australia has adopted a novel Health Star Rating (HSR) system, but the legitimacy of this choice is unknown. Objective: To define the effects of different formats of front-of-pack labelling on the healthiness of food purchases and consumer perceptions. Design: Individuals were assigned at random to access one of four different formats of nutrition labellingHSR, multiple traffic light labels (MTL), daily intake guides (DIG), recommendations/warnings (WARN)or control (the nutrition information panel, NIP). Participants accessed nutrition information by using a smartphone application to scan the bar-codes of packaged foods, while shopping. The primary outcome was healthiness defined by the mean transformed nutrient profile score of packaged foods that were purchased over four weeks. Results: The 1578 participants, mean age 38 years, 84% female recorded purchases of 148,727 evaluable food items. The mean healthiness of the purchases in the HSR group was non-inferior to MTL, DIG, or WARN (all p < 0.001 at 2% non-inferiority margin). When compared to the NIP control, there was no difference in the mean healthiness of purchases for HSR, MTL, or DIG (all p > 0.07), but WARN resulted in healthier packaged food purchases (mean difference 0.87; 95% confidence interval 0.03 to 1.72; p = 0.04). HSR was perceived by participants as more useful than DIG, and easier to understand than MTL or DIG (all p < 0.05). Participants also reported the HSR to be easier to understand, and the HSR and MTL to be more useful, than NIP (all p < 0.03). Conclusions: These real-world data align with experimental findings and provide support for the policy choice of HSR. Recommendation/warning labels warrant further exploration, as they may be a stronger driver of healthy food purchases.
