检查电子烟使用的流行率，电子烟和烟草使用的流行率，以及电子烟使用与威尔士年轻人的社会人口特征，烟草和大麻使用的关联。数据来自2013-2014年进行的两次全国代表性横断面调查。Logistic回归分析，调整学校层面的聚类，检查电子烟使用的社会人口统计学特征，以及电子烟使用与吸烟之间的关联。威尔士的中小学。10-11岁小学生（n=1601）和11-16岁中学生（n=9055）。小学生更有可能使用电子烟（5.8%）而不是烟草（1.6%）。在14-15岁之前，电子烟的使用仍然比烟草的使用更普遍。总体而言，12.3%的中学生（11-16岁）报告曾经使用过电子烟，性别，种族或家庭富裕程度没有差异。报告使用电子烟的“从不吸烟者”的比例在10-11岁时为5.3%，在15-16岁时为8.0%。曾经使用过电子烟并报告目前吸烟的儿童比例从10-11奥尔兹的6.9%增加到15-16奥尔兹的39.2%。 在11-16岁的青少年中，只有1.5%（n=125），包括0.3%的从不吸烟者，报告经常使用电子烟（每月至少使用一次）。目前每周吸烟者报告经常使用电子烟的可能性是非吸烟者的100倍（相对风险比（RR =121.15; 95% CI 57.56至254.97））。在吸食大麻的人中，经常使用电子烟的可能性也更大（RRR 53.03; 95% CI 38.87至80.65）。许多年轻人（包括从不吸烟的人）都尝试过电子烟。然而，经常使用不太常见，并且与烟草卷烟的使用有关。需要进行纵向研究，以了解与年龄相关的电子烟使用轨迹，并了解电子烟与烟草使用之间关系的时间性质。
To examine the prevalence of electronic(e)-cigarette use, prevalence of e-cigarette and tobacco use by age, and associations of e-cigarette use with sociodemographic characteristics, tobacco and cannabis use among young people in Wales. Data from two nationally-representative cross-sectional surveys undertaken in 2013–2014. Logistic regression analyses, adjusting for school-level clustering, examined sociodemographic characteristics of e-cigarette use, and associations between e-cigarette use and smoking. Primary and secondary schools in Wales. Primary-school children aged 10–11 (n=1601) and secondary-school students aged 11–16 (n=9055). Primary-school children were more likely to have used e-cigarettes (5.8%) than tobacco (1.6%). Ever use of e-cigarettes remained more prevalent than ever use of tobacco until age 14–15. Overall, 12.3% of secondary-school students (aged 11–16) reported ever using e-cigarettes, with no differences according to gender, ethnicity or family affluence. The percentage of ‘never smokers’ reporting having used e-cigarettes was 5.3% at age 10–11 to 8.0% at age 15–16. The proportion of children who had ever used an e-cigarette and reported currently smoking increased from 6.9% among 10–11 year olds to 39.2% in 15–16 year olds. Only 1.5% (n=125) of 11–16 year-olds, including 0.3% of never smokers, reported regular e-cigarette use (use at least once a month). Current weekly smokers were 100 times more likely than non-smokers to report regular e-cigarette use (relative risk ratio (RRR=121.15; 95% CI 57.56 to 254.97). Regular e-cigarette use was also more likely among those who had smoked cannabis (RRR 53.03; 95% CI 38.87 to 80.65). Many young people (including never-smokers) have tried e-cigarettes. However, regular use is less common, and is associated with tobacco cigarette use. Longitudinal research is needed to understand age-related trajectories of e-cigarette use and to understand the temporal nature of relationships between e-cigarette and tobacco use.
