摘要目的:调查浙江省大学生烟草使用情况，分析校内二手烟暴露的影响因素。方法:采用多阶段整群抽样方法，于2021年抽取浙江省9所高等学校的在校大学生进行问卷调查，发放6 530份，收回6 035份，有效问卷6 030份（96.48%）；对调查对象的人口学特征、卷烟和电子烟使用情况、以及二手烟暴露情况进行描述性分析，不同特征大学生二手烟暴露情况的比较采用 χ2检验，校内二手烟暴露的影响因素分析采用多因素logistic回归分析。 结果:浙江省大学生现在吸烟率和现在电子烟使用率分别为3.70%和1.56%，卷烟和电子烟双重使用率为1.16%；大学生校内二手烟暴露率为25.06%，校外场所二手烟暴露率为32.35%。大学生对吸烟导致疾病的知晓率依次为：肺癌（92.02%）、心脏病（73.15%）、卒中（72.87%）、阳痿（64.08%）；二手烟导致疾病的知晓率依次为：成人肺癌（91.11%）、成人心脏疾病（78.91%）、儿童肺部疾病（89.35%）。多因素logistic回归分析结果显示：性别、学校类型、专业、年级、禁烟规定、吸烟镜头、二手烟危害健康知识等7个因素对大学生在校遭受二手烟暴露产生影响［ OR值=2.63、0.67、0.69、（0.39、0.60、0.68）、0.51、1.74、0.72］（均 P<0.01）。 结论:浙江省大学生卷烟和电子烟使用情况不容乐观，尤其是电子烟使用率甚至高于成人水平；大学生二手烟暴露状况依然严峻，男生、非医学类、专科生、高年级的大学生校内二手烟暴露更为严重，二手烟暴露知识认知率高、媒体吸烟镜头接触少、学校有全面无烟规定的大学生在校内二手烟暴露较轻。

abstractsObjective:To describe the prevalence of tobacco use among college students in Zhejiang Province and analyze the influencing factors of second-hand smoke exposure on campus.Methods:In 2021, college students were selected from 9 colleges through stratified multi-stage cluster sampling from Zhejiang Province and surveyed using questionnaire. A total of 6 530 questionnaires were distributed and 6 035 were returned, with 6 030 valid questionnaires (96.48%). A descriptive analysis of the demography characteristics, cigarettes and electronic cigarettes (e-cigarettes) use, and second-hand smoke exposure of the subjects was carried out, and chi-square test was used for statistical analysis and multivariate logistic regression analysis was used to analyze influencing factors of second-hand smoke exposure on campus.Results:The current smoking rate and current use rate of e-cigarettes among college students were 3.70% and 1.56%, respectively, and the dual use rate of cigarettes and e-cigarettes was 1.16%. The exposure rate of second-hand smoke among college students on campus was 25.06%, while the exposure rate of second-hand smoke in off campus places was 32.35%. The awareness rates of smoking related diseases among college students were as follows: lung cancer (92.02%), heart disease (73.15%), stroke (72.87%), and impotence (64.08%). The awareness rate of second-hand smoke related diseases were as follows: lung cancer in adults (91.11%), heart disease in adults (78.91%), and lung disease in children (89.35%). The multivariate logistic regression analysis showed that seven factors (including gender, school type, major, grade, smoking ban regulations, smoking scenes, and knowledge about the health hazards of second-hand smoke) had a statistically significant impact on college students′ exposure to second-hand smoke at school [ OR=2.63, 0.67, 0.69, (0.39, 0.60, 0.68), 0.51, 1.74, 0.72] (all P<0.01). Conclusions:The use of cigarettes and e-cigarettes among college students in Zhejiang Province is not optimistic, especially the use rate of e-cigarettes is higher than adult. The status of second-hand smoke exposure among college students remains serious, with male students, non-medical students, students of special programs, and senior college students having more severe second-hand smoke exposure on campus, and students with high awareness of second-hand smoke exposure, less exposure to smoking scenes from media, from college with comprehensive smoke-free regulations are less exposed to second-hand smoke on campus.
