导读：电子烟（电子烟）作为普通香烟的替代品越来越受欢迎，因为它们被认为危害更小。然而，目前尚不清楚美国民众对电子烟的认知程度。这项研究旨在扩展之前的研究，并研究电子烟意识和感知危害的趋势，以及它们与戒烟努力的关系。方法：将2012年、2013年和2014年卫生信息全国趋势调查三个周期的数据合并为一个数据集。控制调查年份，使用多元logit模型确定人口统计学特征与电子烟意识、感知危害、戒烟尝试和戒烟意图之间的关系。数据于2015年进行分析。结果：电子烟知晓率从2012年的77.1%上升到2014年的94.3%。控制人口统计特征，2013年和2014年的电子烟意识相对于2012年显著提高。认为电子烟比普通香烟危害小的看法从2012年的50.7%下降到2014年的43.1%。在吸烟者中，没有观察到电子烟意识与过去一年的戒烟尝试或戒烟意图之间的关系，但那些认为电子烟危害较小的人过去一年戒烟尝试的可能性较小。结论：这些分析表明，公众对电子烟的整体认识不断提高，与普通香烟相比，对电子烟的危害认知也在不断变化。美国食品和药物管理局的新监管可能对这两个方面产生重大影响，值得继续监测。(C) 2016美国预防医学杂志。Elsevier Inc.出版。版权所有。
Introduction: Electronic cigarettes (e-cigarettes) are gaining in popularity as an alternative to regular cigarettes, as they are viewed as potentially less harmful. However, it remains unclear how awareness about e-cigarettes is permeating through the general U.S. population. This study seeks to extend previous research and examine trends in e-cigarette awareness and perceived harmfulness, and their association with smoking-cessation efforts.Methods: Data from three cycles (2012, 2013, and 2014) of the Health Information National Trends Survey were combined into a single data set. Controlling for survey year, multivariate logit models were used to determine the association between demographic characteristics and e-cigarette awareness, perceived harmfulness, quit attempts, and quit intentions. Data were analyzed in 2015.Results: Awareness of e-cigarettes increased from 77.1% in 2012 to 94.3% in 2014. Controlling for demographic characteristics, e-cigarette awareness significantly increased in both 2013 and 2014, relative to 2012. Perception that e-cigarettes were less harmful than regular cigarettes declined from 50.7% in 2012 to 43.1% in 2014. Among smokers, no relationship was observed between e-cigarette awareness and past-year quit attempts or quit intentions, but those that viewed e-cigarettes as less harmful were less likely to have a past-year quit attempt.Conclusions: These analyses reveal a continued increase in overall public awareness of e-cigarettes and shifting harm perceptions relative to regular cigarettes. New regulatory oversight by the U.S. Food and Drug Administration may have major effects on both dimensions, which are worth continued monitoring. (C) 2016 American Journal of Preventive Medicine.
