我们估计了美国成年人对电子烟(电子尼古丁传递系统)的认识、使用和危害认知。我们的数据来自2010年进行的两项调查：一项全国性在线研究(n=2649)和遗留纵向吸烟者队列(n=3658)。我们使用多变量模型来检查电子烟的认知、使用和危害感知。在在线调查中，40.2%(95%可信区间[CI]=37.3，43.1)听说过电子烟，目前吸烟者的知晓率最高。现在吸烟者的吸烟率(11.4%；95%CI=9.3，14.0)高于总人口(3.4%；95%CI=2.6，4.2)，以前吸烟者的使用率为2.0%(95%CI=1.0，3.8)，从不吸烟者的使用率为0.8%(95%CI=0.35，1.7)。在这两项调查中，非西班牙裔白人、目前吸烟者、年轻人和那些至少拥有高中文凭的人最有可能认为电子烟比普通香烟的危害小。人们对电子烟的认知度很高，现在和以前的吸烟者中使用电子烟的情况很明显。我们建议进行产品监管和仔细监测，以监测对公众健康的影响和新出现的使用模式，并确定为什么、如何以及在什么条件下使用电子烟。
We estimated e-cigarette (electronic nicotine delivery system) awareness, use, and harm perceptions among US adults. We drew data from 2 surveys conducted in 2010: a national online study (n = 2649) and the Legacy Longitudinal Smoker Cohort (n = 3658). We used multivariable models to examine e-cigarette awareness, use, and harm perceptions. In the online survey, 40.2% (95% confidence interval [CI] = 37.3, 43.1) had heard of e-cigarettes, with awareness highest among current smokers. Utilization was higher among current smokers (11.4%; 95% CI = 9.3, 14.0) than in the total population (3.4%; 95% CI = 2.6, 4.2), with 2.0% (95% CI = 1.0, 3.8) of former smokers and 0.8% (95% CI = 0.35, 1.7) of never-smokers ever using e-cigarettes. In both surveys, non-Hispanic Whites, current smokers, young adults, and those with at least a high-school diploma were most likely to perceive e-cigarettes as less harmful than regular cigarettes. Awareness of e-cigarettes is high, and use among current and former smokers is evident. We recommend product regulation and careful surveillance to monitor public health impact and emerging utilization patterns, and to ascertain why, how, and under what conditions e-cigarettes are being used.
