背景技术背景：在美国，电子烟的使用在青少年中迅速增加，一些人认为电子烟是青少年吸烟减少的原因。我们假设，在2007年电子烟进入美国市场后，青少年吸烟率的下降发生了变化。方法：数据收集来自2004-2014年全国青少年烟草调查（样本范围从2013年的16 614到2004年的25 324）的六年级到12年级的横断面，全国代表性的校本样本。通过使用曾经（>= 1次抽吸）和当前（最近30天）吸烟的中断时间序列进行分析。Logistic回归用于确定2004-2009年样本中与吸烟相关的心理社会风险因素;然后应用该模型估计2011-2014年样本中吸烟者和电子烟使用者吸烟的概率。2004年至2014年，青少年吸烟率呈线性下降（曾经吸烟的P = 0.009，目前吸烟的P = 0.05），2009年后这一趋势没有显著变化（P = 0.57和0.23）。基于吸烟的心理社会模型，包括人口统计学特征，愿意穿带有烟草标志的衣服，与吸烟者一起生活，下一年吸烟的可能性，从朋友那里吸烟的可能性，以及使用香烟或电子烟以外的烟草产品，该模型将< 25%的当前仅使用电子烟的用户分类（2012年为11.0%，2013年为23.1%）。电子烟的引入与年轻人吸烟量线性下降的变化无关。仅使用电子烟的用户不太可能开始使用烟草产品。
BACKGROUND: E-cigarette use is rapidly increasing among adolescents in the United States, with some suggesting that e-cigarettes are the cause of declining youth cigarette smoking. We hypothesized that the decline in youth smoking changed after e-cigarettes arrived on the US market in 2007.METHODS: Data were collected by using cross-sectional, nationally representative schoolbased samples of sixth-through 12th-graders from 2004-2014 National Youth Tobacco Surveys (samples ranged from 16 614 in 2013 to 25 324 in 2004). Analyses were conducted by using interrupted time series of ever (>= 1 puff) and current (last 30 days) cigarette smoking. Logistic regression was used to identify psychosocial risk factors associated with cigarette smoking in the 2004-2009 samples; this model was then applied to estimate the probability of cigarette smoking among cigarette smokers and e-cigarette users in the 2011-2014 samples.RESULTS: Youth cigarette smoking decreased linearly between 2004 and 2014 (P = .009 for ever smoking and P = .05 for current smoking), with no significant change in this trend after 2009 (P = .57 and .23). Based on the psychosocial model of smoking, including demographic characteristics, willingness to wear clothing with a tobacco logo, living with a smoker, likelihood of smoking in the next year, likelihood of smoking cigarettes from a friend, and use of tobacco products other than cigarettes or e-cigarettes, the model categorized < 25% of current e-cigarette-only users (between 11.0% in 2012 and 23.1% in 2013) as current smokers.CONCLUSIONS: The introduction of e-cigarettes was not associated with a change in the linear decline in cigarette smoking among youth. E-cigarette-only users would be unlikely to have initiated tobacco product use with cigarettes.
