Studies examining e-cigarette use among adolescents in Shanghai, China, have focused largely on middle school students. Given the vast differences between vocational and traditional schools, we aimed to explore school-type differences in e-cigarette use and correlates among adolescents in Shanghai.
The study was conducted in September 2017 through multistage and stratified cluster random sampling, which consisted of 10699 adolescents aged 13-17 years attending traditional and vocational schools in Shanghai. Descriptive statistics and multivariate logistic regressions were conducted to assess the weighted prevalence and correlates of ever e-cigarette use stratified by school type.
The weighted prevalence of e-cigarette use was 5.21% among all respondents. Although e-cigarette use was more prevalent among students attending vocational schools (p<0.001), its correlates were similar across both school types. Among vocational school students, ever tobacco use (OR=3.10; 95% CI: 2.36-4.08) was the most significant correlate, followed by having most friends as smokers (OR=2.97; 95% CI: 1.84-4.81) and having morning cravings (OR=1.90; 95% CI: 1.64-2.20). Among traditional school students, having most friends as smokers (OR=4.87; 95% CI: 2.78-8.54) and ever tobacco use (OR=3.78; 95% CI: 2.68-5.34) were the most significant correlates, followed by knowledge of pro-tobacco advertisements (OR=2.12; 95% CI: 1.54-2.91).
Joint efforts from the national, school and family levels are needed to control e-cigarette use among adolescents in China, and such efforts should be tailored to address differences in school characteristics.
在中国上海，针对青少年电子烟使用情况的研究主要聚焦于中学生。鉴于职业学校和传统学校存在巨大差异，我们旨在探究上海青少年电子烟使用情况及相关因素在学校类型上的差异。
该研究于2017年9月通过多阶段分层整群随机抽样进行，研究对象为上海市10699名年龄在13至17岁的传统学校和职业学校学生。采用描述性统计和多变量逻辑回归分析，评估按学校类型分层的电子烟使用加权患病率及相关因素。
所有受访者中电子烟使用加权患病率为5.21%。尽管职业学校学生中电子烟使用更为普遍（p<0.001），但其相关因素在两种学校类型中相似。在职业学校学生中，曾经使用烟草（OR=3.10；95%CI：2.36 - 4.08）是最显著的相关因素，其次是大多数朋友为吸烟者（OR=2.97；95%CI：1.84 - 4.81）和有晨起渴望（OR=1.90；95%CI：1.64 - 2.20）。在传统学校学生中，大多数朋友为吸烟者（OR=4.87；95%CI：2.78 - 8.54）和曾经使用烟草（OR=3.78；95%CI：2.68 - 5.34）是最显著的相关因素，其次是了解支持烟草的广告（OR=2.12；95%CI：1.54 - 2.91）。
中国需要国家、学校和家庭层面共同努力，控制青少年电子烟使用，且这些努力应根据学校特点差异进行调整。
