背景：很少有全国性的调查记录电子烟在美国的使用情况。现有的评估电子烟使用情况的指标很可能是指最近尝试过电子烟但没有继续使用该产品的个人。目的：在一项具有全国代表性的调查中记录电子烟的流行率，调查对象是美国现在和以前的吸烟者。方法：2013年6月，对现在和以前吸烟的人进行了随机抽样，完成了一项基于网络的调查(n=2,136)。2013年11月对数据进行了分析。多变量Logistic回归确定了与每个使用类别相关的人口统计学和吸烟相关因素。95%的CI描述了每组人的电子烟使用行为(例如，首选品牌、购买模式)。结果：近一半的受访者尝试过电子烟(46.8%)，但已建立的使用率仍然很低(3.8%)。虽然在日常吸烟者中尝试电子烟的几率最高，但在既往吸烟者中，确定使用电子烟的几率更高(OR=3.24，95%CI=1.13，9.30，p
Background: Few national surveys document the prevalence of e-cigarette use in the U.S. The existing metric to assess current use likely identifies individuals who have recently tried an e-cigarette but do not continue to use the product.Purpose: To document the prevalence of e-cigarette ever use, current use, and established use in a nationally representative survey of current and former cigarette smokers in the U.S.Methods: A random sample of current and former cigarette smokers completed a web-based survey in June 2013 (n=2,136). Data were analyzed in November 2013. Multivariate logistic regression identified demographic and smoking-related factors associated with each use category. Point estimates with 95% CIs described e-cigarette use behaviors (e.g., preferred brand, purchasing patterns) for each group.Results: Almost half of respondents had tried e-cigarettes (46.8%), but prevalence of established use remained low (3.8%). Although trial of e-cigarettes was highest among daily smokers, the odds of being an established e-cigarette user were greater for former smokers (OR=3.24, 95% CI=1.13, 9.30, p
