Electronic cigarettes (e-cigarettes) are now the most commonly used tobacco product among US youth. The extent to which perceptions of e-cigarettes' harm and addictiveness differ from those of other products remains unknown, as does whether these perceptions have changed over time.
Data from the 2012 and 2014 National Youth Tobacco Survey, a repeated cross-sectional survey of grade 6 to 12 students, were used. Cross-tabulations and logistic regression models were used to describe correlates of perceptions of harm and addictiveness of e-cigarettes, cigars, and smokeless tobacco compared with cigarettes. Trends in perceptions of e-cigarettes' harm among different demographic groups were also assessed.
In 2014, 73.0% believed that e-cigarettes were less harmful than cigarettes, compared with 20.2% for smokeless tobacco and 25.8% for cigars. By comparison, 47.1% believed that e-cigarettes were less addictive than cigarettes, compared with only 14.0% for smokeless tobacco and 31.5% for cigars. Use of each product was associated with a perception of decreased harm and addictiveness in adjusted analyses, as was being male, being a non-Hispanic white, and residing with a household member who used that product. Between 2012 and 2014, increasing numbers of US youth thought they were able to assess the relative harm of e-cigarettes and increasingly believed that e-cigarettes are less harmful than cigarettes.
Most US youth view e-cigarettes as less harmful and addictive than cigarettes. Far fewer think similarly about cigars and smokeless tobacco. Increases in e-cigarettes' perceived safety mirrors rapid increases observed in their use. Perceived safety correlates with use of each tobacco product.
电子烟目前是美国青少年中最常用的烟草产品。电子烟的危害和成瘾性认知与其他产品的差异程度尚不清楚,这些认知是否随时间变化也不清楚。
使用了2012年和2014年全国青少年烟草调查的数据,这是一项对6至12年级学生的重复横断面调查。交叉表和逻辑回归模型用于描述与香烟相比,对电子烟、雪茄和无烟烟草的危害和成瘾性认知的相关因素。还评估了不同人口群体对电子烟危害认知的趋势。
2014年,73.0%的人认为电子烟比香烟危害小,相比之下,无烟烟草为20.2%,雪茄为25.8%。相比之下,47.1%的人认为电子烟比香烟成瘾性小,相比之下,无烟烟草仅为14.0%,雪茄为31.5%。在调整分析中,使用每种产品都与危害和成瘾性降低的认知相关,男性、非西班牙裔白人以及与使用该产品的家庭成员同住也与这种认知相关。在2012年至2014年期间,越来越多的美国青少年认为他们能够评估电子烟的相对危害,并且越来越相信电子烟比香烟危害小。
大多数美国青少年认为电子烟比香烟危害小且成瘾性低。认为雪茄和无烟烟草同样如此的人要少得多。电子烟感知安全性的提高反映了其使用量的快速增加。感知安全性与每种烟草产品的使用相关。
