Alcohol labels are one strategy for raising consumer awareness about the negative consequences of alcohol, but evidence to inform labels is limited. This quasi-experimental study sought to test the real-world impact of strengthening health messages on alcohol container labels on consumer attention, message processing (reading, thinking, and talking with others about labels), and self-reported drinking. Alcohol labels with a cancer warning, national drinking guidelines, and standard drink information were implemented in the intervention site, and usual labelling practices continued in the comparison site. Changes in key indicators of label effectiveness were assessed among a cohort of adult drinkers in both the intervention and comparison sites using three waves of surveys conducted before and at two time-points after the alcohol label intervention. Generalized Estimating Equations with difference-in-difference terms were used to examine the impact of the label intervention on changes in outcomes. Strengthening health messages on alcohol container labels significantly increased consumer attention to [Adjusted Odds Ratio (AOR)=17.2, 95%CI:8.2,36.2] and processing of labels (e.g., reading labels: AOR=2.6, 95%CI:1.8,3.7), and consumer reports of drinking less due to the labels (AOR=3.7, 95%CI: 2.0,7.0). Strengthening health messages on alcohol containers can achieve their goal of attracting attention, deepening engagement, and enhancing motivation to reduce alcohol use. Strengthening alcohol labelling policies should be a priority for alcohol control globally.
酒精标签是提高消费者对酒精负面影响的意识的一种策略，但用于告知标签的证据有限。本准实验研究旨在测试在酒精容器标签上强化健康信息对消费者注意力、信息处理（阅读、思考和与他人讨论标签）以及自我报告饮酒量的实际影响。干预点实施了带有癌症警告、国家饮酒指南和标准饮酒量信息的酒精标签，而比较点则继续使用常规标签。在干预点和比较点的成年饮酒者队列中，使用在干预前和干预后两个时间点进行的三次调查，评估了标签有效性的关键指标的变化。使用差异中的差异广义估计方程来检验标签干预对结果变化的影响。强化酒精容器标签上的健康信息显著增加了消费者对标签的关注（调整后的优势比（AOR）=17.2，95%CI：8.2，36.2）和标签处理（例如，阅读标签：AOR=2.6，95%CI：1.8，3.7），以及消费者因标签而减少饮酒的报告（AOR=3.7，95%CI：2.0，7.0）。强化酒精容器上的健康信息可以实现吸引注意力、深化参与度和增强减少饮酒动机的目标。强化酒精标签政策应该成为全球酒精控制的优先事项。
