背景:酒精警告标签很有希望,有针对性的战略,以提高公众对酒精相关健康风险的认识,并支持更知情和更安全的使用。然而,它们在现实世界中的有效性的证据仍然有限和不确定。
目的:本文提出了一项真实世界研究的协议,该研究检查了带有癌症信息的增强型酒精警告标签对人群水平的影响;国家饮酒指南;以及有关注意的标准饮酒信息,processing,以及加拿大消费者中与酒精相关的行为。还描述了由于国家酒精行业代表的干扰而对原始方案的后期实施修改。
方法:这项准实验研究涉及与加拿大北部两个地区的地方政府合作,这些地方政府已经在酒类商店出售的酒精容器上贴上了酒精警告标签。该研究测试了一项为期8个月的干预措施,包括三项新的增强措施,在干预地点旋转酒精警告标签(Whitehorse,育空地区)相对于比较地点(Yellowknife,西北地区),标签做法将保持不变。在两个地点都进行了事后调查,以衡量标签信息的认识和处理方面的变化,酒精相关知识,和行为。从两个站点收集了酒类商店交易数据,以评估人口水平酒精消费的变化。干预措施成功实施了1个月,然后由于酒精行业的投诉而中止。干预地点的政府允许研究在暂停两个月后继续进行,条件是癌症警告标签从轮换中删除。对方案的修改包括应用剩余的两个增强标签以平衡干预,并在2个月的暂停期间添加第三波调查以捕获癌症标签的任何影响。
结果:本研究方案描述了一项现实世界的准实验研究,旨在测试新的增强型酒精警告标签的有效性,以支持消费者做出更明智和更安全的酒精选择。实施后不久,酒精行业的干扰损害了干预和原始研究设计;然而,对研究设计进行了修改,以完成对队列参与者(n=2049)的三波调查,并达到研究目标.
结论:这项研究的结果将直接为加拿大和国际上的酒精标签政策提供信息,并为酒精行业破坏该领域研究的尝试提供进一步的见解。建议对增强的酒精警告标签进行其他不受阻碍的现实评估。

BACKGROUND: Alcohol warning labels are a promising, well-targeted strategy to increase public awareness of alcohol-related health risks and support more informed and safer use. However, evidence of their effectiveness in real-world settings remains limited and inconclusive.
OBJECTIVE: This paper presents a protocol for a real-world
study examining the population-level impact of enhanced alcohol warning labels with a cancer message; national drinking guidelines; and standard drink information on attention, processing, and alcohol-related behaviors among consumers in Canada. Postimplementation modifications to the original protocol due to interference by national alcohol industry representatives are also described.
METHODS: This quasi-experimental
study involved partnering with local governments in two northern Canadian territories already applying alcohol warning labels on alcohol containers for sale in liquor stores. The
study tested an 8-month intervention consisting of three new enhanced, rotating alcohol warning labels in an intervention site (Whitehorse, Yukon) relative to a comparison site (Yellowknife, Northwest Territories) where labelling practices would remain unchanged. Pre-post surveys were conducted at both sites to measure changes in awareness and processing of label messages, alcohol-related knowledge, and behaviors. Liquor store transaction data were collected from both sites to assess changes in population-level alcohol consumption. The intervention was successfully implemented for 1 month before it was halted due to complaints from the alcohol industry. The government of the intervention site allowed the study to proceed after a 2-month pause, on the condition that the cancer warning label was removed from rotation. Modifications to the protocol included applying the two remaining enhanced labels for the balance of the intervention and adding a third wave of surveys during the 2-month pause to capture any impact of the cancer label.
RESULTS: This
study protocol describes a real-world quasi-experimental
study that aimed to test the effectiveness of new enhanced alcohol warning labels as a tool to support consumers in making more informed and safer alcohol choices. Alcohol industry interference shortly after implementation compromised both the intervention and the original study design; however, the study design was modified to enable completion of three waves of surveys with cohort participants (n=2049) and meet the
study aims.
CONCLUSIONS: Findings from this study will directly inform alcohol labelling policies in Canada and internationally and provide further insight into the alcohol industry\'s attempts to disrupt research in this area. Additional unimpeded real-world evaluations of enhanced alcohol warning labels are recommended.
