Abstract:
Objective:To describe the current situation and influencing factors of e-cigarette use among secondary school students in Heilongjiang Province to provide evidence for formulating provincial youth e-cigarette prevention and control strategies.Methods:A multi-stage stratified cluster probability sampling method was adopted in 2021, with 8 340 students in 180 classes from 56 primary and high schools in 10 monitoring districts and counties in Heilongjiang Province. The students in the selected classes filled out a unified questionnaire by themselves. SAS 9.4 software was used for data cleansing, sample weighting, and analysis. Chi-squared tests were used to compare the differences between groups, and a two-level logistic regression model was used to analyze the influencing factors of e-cigarette use among secondary school students.Results:A total of 8 329 survey questionnaires were included in the analysis. The prevalence rates of ever and current e-cigarette use among secondary school students in Heilongjiang Province were 18.27% and 5.46%, respectively. In terms of ever e-cigarette use, the rate of boys (23.94%) was higher than that of girls (12.35%). The rate of vocational high school students (39.18%) was higher than that of general high school students (24.11%) and than that of junior school students (11.27%). In terms of current e-cigarette use, the rate of boys (7.08%) was higher than that of girls (3.76%). The rate of vocational high school students (14.56%) was higher than that of general high school students (7.70%) and than that of junior school students (2.67%). The rates of ever and current e-cigarette use were relatively higher in each subgroup, including "weekly allowance more than 40 Yuan" "one of the student's parents, friends or teachers was smoker" "smoked cigarettes now" and "saw e-cigarette advertisements". A two-level logistic regression model showed that the following factors were the influencing factors of current use of e-cigarettes among secondary school students, including gender, whether they were current cigarette smokers, the smoking status of their close friends, if they saw teachers smoked in the school, noticed e-cigarette advertisements, and e-cigarette addictive cognition.Conclusions:The prevalence rates of ever and current e-cigarette use among secondary school students in Heilongjiang Province were high. E-cigarette advertisements, the smoking status of their close friends, and whether they saw teachers smoking in the school were the main factors affecting e-cigarette use among secondary school students in Heilongjiang Province. It is necessary to focus on constructing smoke-free environments and increase health education related to e-cigarette knowledge on risk in developing a smoke-free campus in the whole province.
