To examine: (1) How perceptions of harm for seven non-cigarette tobacco products predict subsequent use; (2) How change in use is associated with changes in perceptions of product harm; (3) Whether sociodemographic variables moderate the association between perceptions and use.
Data are from the adult sample (18+) of the Population Assessment of Tobacco and Health (PATH) Study, a nationally representative longitudinal cohort survey conducted September 2013-December 2014 (Wave 1 (W1) n = 32,320) and October 2014-October 2015 (Wave 2 (W2) n = 28,362).
Wave 1 users and non-users of e-cigarettes, filtered cigars, cigarillos, and pipes, who perceived these products as less harmful had greater odds of using the product at W2. For the other products, there was an interaction between W1 perceived harm and W1 use status in predicting W2 product use. At W2, a smaller percentage of U.S. adults rated e-cigarettes as less harmful than cigarettes compared to W1 (41.2% W1, 29.0% W2). Believing non-cigarette products to be less harmful than cigarettes was more strongly associated with subsequent product use in the oldest age group (55+ years) while weaker effects were observed in the youngest age group (18-24 years). This moderating effect of age was significant for e-cigarettes, hookah, traditional cigars, and cigarillos.
Strategies to prevent initiation and promote cessation of these products may benefit from understanding and addressing perceptions of these products.
研究：（1）对七种非卷烟烟草制品危害的认知如何预测后续使用情况；（2）使用情况的变化与对产品危害认知的变化之间有何关联；（3）社会人口统计学变量是否会调节认知与使用之间的关联。
数据来自烟草与健康人口评估（PATH）研究的成人样本（18岁及以上），这是一项具有全国代表性的纵向队列调查，于2013年9月至2014年12月进行（第1波（W1），n = 32320）以及2014年10月至2015年10月进行（第2波（W2），n = 28362）。
在第1波中，认为电子烟、过滤嘴雪茄、小雪茄和烟斗危害较小的使用者和非使用者，在第2波中使用这些产品的几率更高。对于其他产品，在预测第2波产品使用情况时，第1波感知危害与第1波使用状态之间存在交互作用。在第2波时，与第1波相比，将电子烟评为危害小于卷烟的美国成年人比例更小（第1波为41.2%，第2波为29.0%）。认为非卷烟产品危害小于卷烟与最年长年龄组（55岁及以上）的后续产品使用关联更强，而在最年轻年龄组（18 - 24岁）观察到的影响较弱。年龄的这种调节作用在电子烟、水烟、传统雪茄和小雪茄方面具有显著性。
预防这些产品的初次使用和促进戒烟的策略可能会受益于了解并应对对这些产品的认知。
