ABSTRACT

Objective@#To investigate the prevalence and influencing factors of electronic cigarette (e-cigarette) use among adolescents in Haidian District, Beijing, so as to provide insights into tobacco control among adolescents.@*Methods@#The students in junior high school, high school and vocational high school were recruited from Haidian District using the stratified cluster random sampling method in October of 2019, and subjects' demographic features and use of e-cigarettes were collected using the Questionnaire for Survey on Tobacco Prevalence among Adolescents in China in 2019. The factors affecting e-cigarette use were identified among adolescents using the multivariable logistic regression analysis.@*Results@#A total of 658 adolescents were investigated, including 315 junior high school students ( 47.87% ), 221 high school students ( 33.59% ), and 122 vocational high school students ( 18.54% ), and there were 261 boys ( 39.66% ), and 397 girls ( 60.34% ). There were 605 students that had heard of electronic cigarettes ( 91.95% ), 63 students that had used e-cigarettes (9.57%), and 23 students with current use of e-cigarettes ( 3.50% ), and there were 39 students that had never used electronic cigarettes but had a tendency of use in the future ( 6.55% ). Multivariable logistic regression analysis identified parental smoking ( OR=2.408, 95%CI 1.179-4.916 ), close friends' smoking ( OR=3.597, 95%CI 1.715-7.544 ) and cigarette smoking ( OR=23.029, 95%CI 11.092-47.812 ) as factors affecting e-cigarette use among adolescents.@*Conclusions@#The prevalence of electronic cigarette uses is 9.57% among adolescents in Haidian District, Beijing. Parental smoking, peer smoking and use of cigarettes may facilitate the use of e-cigarettes among adolescents.
