研究威尔士年轻人使用电子烟的流行率和频率，与社会人口特征，吸烟和其他物质的关联以及电子烟和烟草使用的顺序。2015年对威尔士学校学生进行的横断面调查。威尔士的87所中学。11-16岁学生（n=32 479）。 总体而言，学生报告曾经使用电子烟（18.5%）的可能性几乎是吸烟（10.5%）的两倍。在整个样本中，至少每周使用电子烟的比例为2.7%，在15-16岁的人群中上升至5.7%。几乎一半（41.8%）的日常吸烟者报告说他们经常使用电子烟。在当前的大麻使用者中，定期使用电子烟更为普遍（相对风险比（RRR）=41.82; 95% CI 33.48至52.25）），酗酒者（RRR=47.88; 95% CI 35.77至64.11），甲氧麻黄酮使用者（RRR=32.38; 95% CI 23.05至45.52）和笑气使用者（RRR=3.71; 95% CI 3.04至4.51）。结合人口统计学和吸烟状况的多变量分析显示，只有性别（男性）和烟草使用独立预测电子烟的定期使用（p<0.001）。在尝试过烟草和电子烟的每周吸烟者中（n=877），绝大多数人报告说他们在使用电子烟之前尝试过烟草（n=727; 82.9%）。自2013年以来，年轻人尝试电子烟的人数在威尔士迅速增长，现在几乎是烟草实验的两倍。经常使用几乎翻了一番，并且在从不吸烟者和非吸烟者中越来越多。这些数据表明，年轻人使用电子烟是一个新出现的公共卫生问题，尽管仍然没有证据表明它代表了吸烟的新途径。需要混合方法纵向研究来探索年轻人使用电子烟的原因，并制定干预措施以防止使用的进一步增加。
To examine the prevalence and frequency of electronic (e)-cigarette use among young people in Wales, associations with socio-demographic characteristics, smoking and other substances and the sequencing of e-cigarette and tobacco use. A cross-sectional survey of school students in Wales undertaken in 2015. 87 secondary schools in Wales. Students aged 11–16 (n=32 479). Overall, students were nearly twice as likely to report ever using e-cigarettes (18.5%) as smoking tobacco (10.5%). Use of e-cigarettes at least weekly was 2.7% in the whole sample, rising to 5.7% among those aged 15–16. Almost half (41.8%) of daily smokers reported being regular e-cigarette users. Regular e-cigarette use was more prevalent among current cannabis users (relative risk ratio (RRR)=41.82; 95% CI 33.48 to 52.25)), binge drinkers (RRR=47.88; 95% CI 35.77 to 64.11), users of mephedrone (RRR=32.38; 95% CI 23.05 to 45.52) and laughing gas users (RRR=3.71; 95% CI 3.04 to 4.51). Multivariate analysis combining demographics and smoking status showed that only gender (being male) and tobacco use independently predicted regular use of e-cigarettes (p<0.001). Among weekly smokers who had tried tobacco and e-cigarettes (n=877), the vast majority reported that they tried tobacco before using an e-cigarette (n=727; 82.9%). Since 2013, youth experimentation with e-cigarettes has grown rapidly in Wales and is now almost twice as common as experimentation with tobacco. Regular use has almost doubled, and is increasing among never and non-smokers. These data suggest that e-cigarette use among youth is an emerging public health issue, even though there remains no evidence that it represents a new pathway into smoking. Mixed methods longitudinal research is needed to explore why young people use e-cigarettes, and to develop interventions to prevent further increases in use.
