目的：我们评估了美国成年人使用电子烟的趋势，使用的人口统计学预测因素，以及当前电子烟使用者的吸烟状况。方法：采用混合模式调查，在4年的每一年中获得美国成年人的代表性横断面样本。2010年、2011年、2012年和2013年的样本量分别为3，240、3，097、3，101和3，245。曾经使用电子烟的比例从1.8%（2010年）增加到13.0%（2013年），而目前使用的比例从0.3%增加到6.8%，p <0.001。在所有人口群体中，吸毒流行率均显著增加。2013年，18-24岁的年轻人（14.2%）目前的使用率高于25-44岁（8.6%）、45-64岁（5.5%）和65岁以上（1.2%）的成年人。每日吸烟者（30.3%）和非每日吸烟者（34.1%）目前最有可能使用电子烟，与前吸烟者（5.4%）和从不吸烟者（1.4%）相比，p <0.001。然而，32.5%的当前电子烟使用者是从不吸烟或曾经吸烟的人。结论：在过去的4年中，电子烟的使用和当前的电子烟使用都有快速增长。年轻人和目前吸烟者的使用率最高。虽然吸烟者最有可能使用这些产品，但目前几乎三分之一的使用者是非吸烟者，这表明电子烟有助于原发性尼古丁成瘾和烟草使用的重新正常化。需要在联邦、州和地方各级采取监管行动，以确保这些产品不会导致可预防的慢性病。
Objectives: We assessed trends in use of electronic cigarettes among U.S. adults, demographic predictors of use, and smoking status of current electronic cigarette users.Methods: Mixed-mode surveys were used to obtain representative, cross-sectional samples of U.S. adults in each of 4 years.Results: Sample sizes for 2010, 2011, 2012, and 2013 were 3,240, 3,097, 3,101, and 3,245, respectively. Ever use of electronic cigarettes increased from 1.8% (2010) to 13.0% (2013), while current use increased from 0.3% to 6.8%, p < .001. Prevalence of use increased significantly across all demographic groups. In 2013, current use among young adults 18-24 (14.2%) was higher than adults 25-44 (8.6%), 45-64 (5.5%), and 65+ (1.2%). Daily smokers (30.3%) and nondaily smokers (34.1%) were the most likely to currently use e-cigarettes, compared to former smokers (5.4%) and never-smokers (1.4%), p < .001. However, 32.5% of current electronic cigarette users are never-or former smokers.Conclusions: There has been rapid growth in ever and current electronic cigarette use over the past 4 years. Use is highest among young adults and current cigarette smokers. Although smokers are most likely to use these products, almost a third of current users are nonsmokers, suggesting that e-cigarettes contribute to primary nicotine addiction and to renormalization of tobacco use. Regulatory action is needed at the federal, state, and local levels to ensure that these products do not contribute to preventable chronic disease.
