背景和目的与香烟相比，人们对电子烟危害性的看法可能会影响他们的产品使用决策。我们测试了是否认为电子烟比香烟危害小预测香烟和电子烟双重使用者是否在1年后改变了他们的产品使用状态，成为唯一的电子烟使用者，唯一的香烟吸烟者，或者两种产品类型的非使用者。国家烟草与健康人口评估（PATH）研究。背景美国。在过去30天内在第2波报告使用香烟和电子烟的成年人在第2波报告了他们对电子烟危害的看法，并报告他们在过去30天内是否在第3波使用香烟和电子烟（n = 2211）.测量关键预测因素是与香烟相比，对电子烟危害的第2波感知（“危害较小”、“差不多”、“危害较大”或“不知道”）。关键结果是过去30天使用电子烟和香烟的第3波，分为四类：电子烟专用（即使用电子烟但不吸烟），只吸烟（即使用香烟但不使用电子烟）、两种产品类型的双重使用和两种产品类型的非使用。59.4%的双重使用者认为电子烟的危害小于香烟[95%置信区间（CI）= 56.9，61.9]。与对电子烟危害有其他看法的人相比，认为电子烟危害小于香烟的双重使用者更有可能在1年后成为电子烟的独家使用者[7.5%对2.7%;调整后的比值比（aOR）= 2.9，95% CI = 1.7-4.8]，更有可能保持双重使用者。（39.6 vs 29.9%; aOR = 1.5，95% CI = 1.2-1.8），不太可能成为完全吸烟者（44.8% vs 59.4%; aOR = 0.6，95% CI = 0.5-0.7），并且同样可能成为两种产品类型的非使用者（8.2对8.0%; aOR = 1.1，95%CI = 0.7-1.7）.结论认为电子烟危害小于香烟的美国成年电子烟和香烟双重使用者似乎更有可能转向专门使用电子烟，与对电子烟危害有其他看法的双重使用者相比，更有可能保持双重使用者，并且不太可能在1年后转为单独使用香烟。
Background and aimsPeople's perceptions of the harmfulness of e-cigarettes, compared with cigarettes, may influence their product use decisions. We tested if perceiving e-cigarettes as less harmful than cigarettes predicted whether cigarette and e-cigarette dual users switched their product use status 1 year later, becoming exclusive e-cigarette users, exclusive cigarette smokers, or non-users of both product types.DesignLongitudinal analyses of waves 2 (2014-15) and 3 (2015-16) of the prospective, national Population Assessment of Tobacco and Health (PATH) Study.SettingUnited States.ParticipantsAdults who reported using both cigarettes and e-cigarettes within the past 30 days at wave 2 reported their perceptions of e-cigarette harm at wave 2, and reported whether they used cigarettes and e-cigarettes within the past 30 days at wave 3 (n = 2211).MeasurementsThe key predictor was wave 2 perceptions of e-cigarette harm compared with cigarettes ('less harmful,' 'about the same', 'more harmful' or 'don't know'). The key outcome was wave 3 past 30-day use of e-cigarettes and cigarettes, classified into four categories: exclusive e-cigarette use (i.e. use of e-cigarettes but not cigarettes), exclusive cigarette smoking (i.e. use of cigarettes but not e-cigarettes), dual use of both product types and non-use of both product types.FindingsAt wave 2, 59.4% of dual users perceived e-cigarettes as less harmful than cigarettes [95% confidence interval (CI) = 56.9, 61.9]. Compared with those with other perceptions of e-cigarette harm, dual users who perceived e-cigarettes as less harmful than cigarettes were more likely to become exclusive e-cigarette users 1 year later [7.5 versus 2.7%; adjusted odds ratio (aOR) = 2.9, 95% CI = 1.7-4.8], more likely to remain dual users (39.6 versus 29.9%; aOR = 1.5, 95% CI = 1.2-1.8), less likely to become exclusive cigarette smokers (44.8 versus 59.4%; aOR = 0.6, 95% CI = 0.5-0.7) and similarly likely to become non-users of both product types (8.2 versus 8.0%; aOR = 1.1, 95% CI = 0.7-1.7).ConclusionsUS adult dual users of e-cigarettes and cigarettes who perceive e-cigarettes as less harmful than cigarettes appear to be more likely to switch to exclusive e-cigarette use, more likely to remain dual users and less likely to switch to exclusive cigarette use 1 year later than dual users with other perceptions of e-cigarette harm.
