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. 目的： 描述黑龙江省中学生电子烟使用现状及其影响因素，为制定省级青少年电子烟防控策略提供循证依据。 方法： 2021年采用多阶段分层整群概率抽样方法，涵盖黑龙江省10个监测区（县）56所初、高中学校180个班级在校学生8 340人，抽中班级内学生统一自填问卷。采用SAS 9.4软件进行数据清洗加权和分析。采用χ²检验比较组间差异，采用两水平logistic回归模型分析中学生电子烟使用的影响因素。 结果： 共8 329份调查问卷纳入分析。黑龙江省中学生使用过电子烟和现在使用电子烟的比例分别为18.27%和5.46%。在使用过电子烟方面，男生（23.94%）高于女生（12.35%）；职业高中生（39.18%）高于普通高中生（24.11%）高于初中生（11.27%）。在现在使用电子烟方面，男生（7.08%）高于女生（3.76%）；职业高中生（14.56%）高于普通高中生（7.70%）高于初中生（2.67%）。在一周内可支配的零花钱>40元、身边父母、朋友、教师吸烟、现在吸卷烟、看到过电子烟广告组内，使用过电子烟及现在使用电子烟的比例均在同组内相对较高。两水平logistic回归模型显示，性别、现在是否吸卷烟、好友吸烟状况、是否看到过教师在学校吸烟、是否看到过电子烟广告、对电子烟易感的态度是中学生现在使用电子烟的影响因素。 结论： 黑龙江省中学生使用过电子烟和现在使用电子烟的比例较高。电子烟广告、好友吸烟状况、是否看到过教师在学校吸烟等是影响黑龙江省中学生电子烟使用的主要因素，需要在全省无烟校园建设中，重点关注无烟环境的建设以及增加电子烟危害知识相关健康教育内容。.
