Abstract

Introduction: Widespread misperceptions of the health risks of nicotine could undermine the public health benefits of the Food and Drug Administration's actions, including modified risk tobacco product authorisations and a reduced nicotine product standard for cigarettes.

Methods: 794 US adults (aged 18+) in NORC's AmeriSpeak panel participated in a randomised controlled trial in Spring 2021 to test the effect of three exposures to eight nicotine corrective messages (NCM) on beliefs about nicotine, nicotine replacement therapy (NRT), e-cigarettes and reduced nicotine content (RNC) cigarettes at 3-month follow-up. Analyses conducted in 2022 examined the effect of study condition (NCM (n=393) vs no message control (n=401)) on nicotine beliefs, use intentions and use of nicotine and tobacco products.

Results: Exposure to three NCM doses reduced nicotine (b=-0.33; 95% CI -0.60, -0.07), NRT (b=-0.49; 95% CI -0.85, -0.14), e-cigarette (b=-0.32; 95% CI -0.59, -0.05) and RNC cigarette false beliefs (b=-0.64; 95% CI -1.26, -0.02) compared with the control, controlling for baseline beliefs. Baseline tobacco use and concern about nicotine addiction attenuated intervention effects on false beliefs about RNC cigarettes. There were few intervention effects on intention or use of nicotine and tobacco products.

Conclusions: Repeated exposure to NCM was necessary to reduce false beliefs about nicotine and tobacco products. Future studies will improve understanding of the dose and duration of nicotine education needed to shift intentions and behaviour, as well as tailored content for tobacco product users to achieve similar reductions in false beliefs as non-users.

尼古丁纠正信息对美国成年人尼古丁相关信念的影响:一项随机对照试验。

导言:对尼古丁健康风险的普遍误解可能会破坏食品和药物管理局行动的公共卫生效益，包括修改风险烟草产品授权和降低香烟尼古丁产品标准。方法:2021年春季，NORC AmeriSpeak小组的794名美国成年人(18岁以上)参加了一项随机对照试验，在3个月的随访中，测试三次接触8种尼古丁纠正信息(NCM)对尼古丁、尼古丁替代疗法(NRT)、电子烟和低尼古丁含量(RNC)香烟的影响。2022年进行的分析检查了研究条件(NCM (n=393) vs无信息控制(n=401))对尼古丁信念、使用意图以及尼古丁和烟草制品使用的影响。结果:暴露于三个NCM剂量的尼古丁减少(b=-0.33;95% CI -0.60， -0.07)， NRT (b=-0.49;95% CI -0.85， -0.14)，电子烟(b=-0.32;95% CI -0.59， -0.05)和RNC香烟错误信念(b=-0.64;95% CI -1.26， -0.02)与对照组相比，控制基线信念。基线烟草使用和对尼古丁成瘾的关注减弱了干预对RNC香烟错误信念的影响。对尼古丁和烟草制品的意图或使用几乎没有干预效果。结论:反复接触NCM对减少对尼古丁和烟草制品的错误认知是必要的。未来的研究将提高对改变意图和行为所需的尼古丁教育的剂量和持续时间的理解，以及为烟草制品使用者量身定制的内容，以实现与非使用者相似的减少错误信念。试验注册号:NCT04805515。
