OBJECTIVE Alcohol labels are one strategy for communicating health information to consumers. This study tested the extent to which consumers recalled alcohol labels with national drinking guidelines and examined the impact of labels on awareness and knowledge of the guidelines. METHOD A quasi-experimental study was conducted in two jurisdictions in northern Canada examining the impact of labels on the following outcomes: unprompted and prompted recall of the drinking guideline label message, awareness of the drinking guidelines, and knowledge of the daily and weekly recommended drink limits. The intervention site applied labels with national drinking guidelines, a cancer warning, and standard drink information to alcohol containers in its liquor store, whereas the comparison site did not apply these labels. In total, 2,049 cohort participants in both sites were recruited to complete surveys before and at two time points after the intervention. Changes in outcomes were examined using generalized estimating equations. RESULTS After the intervention, unprompted and prompted recall of the drinking guideline label message increased more in the intervention versus comparison site (adjusted odds ratio [AOR] = 10.8, 95% CI [0.9, 127.6]; AOR = 7.0, 95% CI [3.3, 14.9], respectively). Awareness of the drinking guidelines increased 2.9 times more in the intervention versus comparison site (AOR = 2.9, 95% CI [2.0, 4.3]). In addition, knowledge of the daily and weekly drink limits increased 1.5 and 1.4 times more in the intervention versus comparison site, respectively (daily: AOR = 1.5, 95% CI [1.0, 2.1]; weekly: AOR = 1.4, 95% CI [1.0, 2.0]). CONCLUSIONS Enhanced alcohol labels get noticed and may be an effective population-level strategy for increasing awareness and knowledge of national drinking guidelines.

检查酒精标签对国家饮酒准则的认识和知识的影响：加拿大育空地区的一项现实世界研究

目标酒精标签是向消费者传达健康信息的一种策略。这项研究通过国家饮酒准则测试了消费者回想酒精标签的程度，并研究了标签对准则的认识和了解的影响。方法在加拿大北部的两个司法管辖区进行了一项准实验研究，研究了标签对以下结果的影响：无提示和及时召回饮酒准则标签信息，对饮酒准则的了解以及对每日和每周推荐饮品的了解限制。干预站点在其酒类商店的酒精容器上贴有带有国家饮酒指南，癌症警告和标准饮酒信息的标签，而比较站点未使用这些标签。总共2 在干预之前和之后的两个时间点，招募了两个地点的049名队列参与者以完成调查。使用广义估计方程检查结果的变化。结果干预后，与比较部位相比，干预后无提示和及时召回饮酒准则标签的信息增加了更多（调整后的优势比[AOR] = 10.8，95％CI [0.9，127.6]； AOR = 7.0，95％CI [ 3.3、14.9]）。与对照组相比，干预措施中的饮酒指南意识提高了2.9倍（AOR = 2.9，95％CI [2.0，4.3]）。此外，与比较站点相比，干预中每日和每周饮酒量的知识分别增加了1.5倍和1.4倍（每天：AOR = 1.5，95％CI [1.0，2.1]；每周：AOR = 1.4，95％CI [1.0，2.0]）。
