Abstract

Background: E-cigarette promotional posts with misleading nicotine warning labels on social media may lower adolescents' risk perceptions of e-cigarettes. A between-subject experiment assessed effects of influencers' e-cigarette promotional posts with different nicotine warning labels on adolescents' e-cigarette harm perceptions, susceptibility to e-cigarette use and perceptions of influencer credibility.

Methods: In 2022, adolescents (N=1864, Mage=17 (SD=0.6)) were randomised to view six images and videos featuring influencers promoting e-cigarettes in one of five experimental conditions: two conditions with a 'tobacco-free nicotine' warning label (placed on an e-cigarette in the post or at the top of the post), two conditions with the US Food and Drug Administration (FDA) nicotine warning label (on an e-cigarette in the post or at the top of the post (control)) and one no-label condition. Participants rated influencers' credibility (eg, honesty). Harm perceptions of, and susceptibility to use, e-cigarettes were then assessed.

Results: Participants who viewed posts with the FDA warning label at the top of the post perceived influencers as more honest, trustworthy and informed than in all the other conditions. E-cigarette never-users who viewed posts with a 'tobacco-free nicotine' warning label pictured on an e-cigarette (compared with the FDA label at the top of a post) were more likely to report susceptibility to e-cigarette use (adjusted OR 1.79, 95% CI 1.17 to 2.73).

Conclusions: Alterations of the required nicotine warning labels can make them less effective in deterring e-cigarette use behaviour. Tobacco control authorities could increase enforcement of the FDA-required nicotine warning labels and harness influencers for antitobacco messaging.

美国青少年对有影响力的电子烟营销社交媒体帖子中尼古丁警告标签的反应:基于调查的随机受试者间实验。
背景:社交媒体上带有误导性尼古丁警告标签的电子烟宣传帖子可能会降低青少年对电子烟的风险认知。一项受试者间实验评估了影响者发布的带有不同尼古丁警告标签的电子烟宣传帖子对青少年电子烟危害感知、电子烟使用易感性和影响者可信度感知的影响:2022年,青少年(N=1864,Mage=17(SD=0.6))被随机分配到五个实验条件中的一个,观看六张图片和视频,内容是有影响力的人推广电子烟:两个条件带有 "无烟草尼古丁 "警示标签(贴在帖子中的电子烟上或帖子顶部),两个条件带有美国食品和药物管理局(FDA)尼古丁警示标签(贴在帖子中的电子烟上或帖子顶部(对照)),一个条件没有标签。参与者对影响者的可信度(如诚实度)进行评分。然后对电子烟的危害认知和使用电子烟的易感性进行评估:结果:与其他所有条件相比,浏览帖子顶部带有 FDA 警告标签的参与者认为影响者更诚实、更可信、更知情。从未使用过电子烟的人在浏览带有电子烟上的 "无烟草尼古丁 "警示标签的帖子时(与FDA在帖子顶部的标签相比),更有可能报告自己容易使用电子烟(调整后的OR值为1.79,95% CI为1.17至2.73):修改规定的尼古丁警示标签会降低其阻止电子烟使用行为的效果。烟草控制机构可以加强对美国食品及药物管理局要求的尼古丁警告标签的执行力度,并利用有影响力的人进行反烟草宣传。
