目标：电子烟市场的近期增长导致了对年轻人使用电子烟的担忧。研究设计：两波横断面调查设计方法：YouGov于2013年和2014年对英国11-18岁的年轻人进行了在线调查。使用电子烟，连同感知的健康危害和使用意图进行了评估和比较有关的吸烟史，年龄和gender.Results：经常使用电子烟从2013年的4.6%（95%CI 3.8-5.7）显着增加到2014年的8.2%（95%CI 7.0-9.6）。每月或每月以上使用电子烟的比例从0.9%（95% CI 0.5-1.5）增加到1.7（1.2-2.4），但在从不吸烟者中仍然很少，低于0.2%。认为电子烟对使用者的危害比香烟小的年轻人比例从73.4%下降到2010年的73.4%。（95% CI 71.0-75.8）至66.9%（95% CI 64.5-69.2），而认为电子烟造成类似危害的比例从11.8%（95%CI 10.0-13.5）增加到18.2%（95%CI 16.3-20.1）。在2014年8.2%的电子烟使用者中，69.8%（95%CI 62.2%-77.3%）在使用电子烟之前吸烟，而8.2%（95%CI 4.1%-12.2%）在使用电子烟后第一次吸烟。年轻人使用电子烟的人数正在增加，但主要限于吸烟者。皇冠版权所有（C）2015由爱思唯尔有限公司代表皇家公共卫生学会出版。All rights reserved.
Objectives: The recent growth in the market for electronic cigarettes (e-cigarettes) has led to concerns over their use by young people. It is therefore important to examine trends in the perception and use of e-cigarettes and conventional cigarettes in this group.Study design: Two-wave cross-sectional survey design.Methods: Young people aged 11-18 in Great Britain were surveyed online by YouGov in 2013 and 2014. Use of e-cigarettes, together with perceived health harms and intention to use were assessed and compared in relation to cigarette smoking history, age and gender.Results: Ever-use of e-cigarettes increased significantly from 4.6% (95% CI 3.8-5.7) in 2013 to 8.2% (95% CI 7.0-9.6) in 2014. Monthly or more use of e-cigarettes increased from 0.9% (95% CI 0.5-1.5) to 1.7 (1.2-2.4), but remained rare in never-smokers at under 0.2%. The proportion of young people who perceived e-cigarettes to be less harmful to users than cigarettes fell from 73.4% (95% CI 71.0-75.8) to 66.9% (95% CI 64.5-69.2), while the proportion who considered e-cigarettes to cause similar levels of harm increased from 11.8% (95% CI 10.0-13.5) to 18.2% (95% CI 16.3-20.1). Of the 8.2% of e-cigarette ever-users in 2014, 69.8% (95% CI 62.2%-77.3%) had smoked a cigarette prior to using an e-cigarette, while 8.2% (95% CI 4.1%-12.2%) first smoked a cigarette after e-cigarette use.Conclusions: A growing proportion of young people in Great Britain believe e-cigarettes are as harmful as smoking tobacco. Use of e-cigarettes by young people is increasing, but is largely confined to those who smoke. Crown Copyright (C) 2015 Published by Elsevier Ltd on behalf of The Royal Society for Public Health.
