Abstract：Objective To investigate the status of electronic cigarette use among adolescents in Ningxia Hui Autonomous Region, and to provide evidence for tobacco control in adolescents. Methods Based on the 2019 National Youth Tobacco Epidemic Monitoring Program, multistage proportional sampling method was used to select middle school students from Ningxia Hui Autonomous Region. A questionnaire revised by Chinese CDC was used to collect the general information, the cognition and use of electronic cigarettes, and the access to advertising of electronic cigarettes and related products. Results Totally 9 019 questionnaires were distributed, 8 401 valid ones were recovered, and the response rate was 93.2%. The rates of electronic cigarette use and attempt among students were 4.3% and 13.4%. The rates of electronic cigarette use and attempt in male students were 7.7% and 22.9%, which were higher than that in female students (0.8% and 3.8%, P<0.05) . The rates of electronic cigarette use and attempt varied in different schools ( P<0.05 ), which were higher in vocational high school students ( 11.5% and 26.8% ). Among 246 students who used electronic cigarettes, 30.1% did not thought electronic cigarettes contained nicotine, while 60.2% did not know whether electronic cigarettes contain nicotine. In the past 30 days, 27.0% of the students had seen the advertisements of electronic cigarettes and related products, mainly through TV, store, supermarket, convenience store, grocery store, electronic cigarette experience store or retail store. Conclusions The rates of electronic cigarette use and attempt among adolescents in Ningxia Hui Autonomous Region are 4.3% and 13.4%. Boys and vocational high school students have higher rates.
