          Abstract

          Objective To understand current situation of e-cigarette use and associated factors in primary and secondary school students in Beijing, in order to promote the construction of smoke-free schools.

          Methods During April to June in 2019, PPS sampling was used to select primary schools, secondary schools and trade schools. In each selected school, randomly sampling method was conducted until the sample size was reached. There were 18 312 students included in the analysis. Surveillance information mainly included the current situation of electronic cigarette use and associated factors.

          Results Among primary and secondary school students who have known about e-cigarettes, female students were less likely to use e-cigarettes than male students ( OR = 0.47, 95% CI = 0.42-0.54). After entering the second year of junior high school, the possibility of using e-cigarettes increased. Smoke-free home was associated less e-cigarettes usage ( OR = 0.78, 95% CI = 0.69-0.88). Primary and secondary school students with average daily allowance of 30~<150 yuan and no less than 150 yuan were 1.43 (95% CI = 1.22-1.67) times and 2.24 (95% CI = 1.79-2.79) times more likely to use e-cigarettes than those with 0-10 yuan allowance, respectively. The probability of using e-cigarettes among primary and secondary school students who have not tried using cigarettes was only 16. 4% compared with those who have tried cigarettes ( OR = 0.16, 95% CI = 0.14-0.19).

          Conclusion It is necessary to curb the prevalence of e-cigarettes among primary and secondary school students. Actions need to be taken urgently to fill in the gaps or correct the mistakes in children and adolescents’ cognition of e-cigarettes, and to adopt more innovative methods to scientifically guide children and adolescents to stay away from e-cigarettes.
