目的了解山东省医学院校学生的吸烟现状,探讨医学生吸烟行为的影响因素,为下一步开展控烟干预活动提供依据。方法从山东省9所医学院校中随机抽取两所,在每所学校中分别采用分层整群随机抽样,以专业和年级为分层特征,运用横断面调查方法,由被调查者自行填写无记名问卷。采用SPSS 13.0软件进行数据录入和分析。根据资料类型及分布特征选择相应指标如率、构成比进行统计描述,并应用χ2检验和logistic回归进行统计学分析,P<0.05为差异有统计学意义。结果调查对象的总尝试吸烟率为27.04%,总现吸烟率为5.05%,其中男生的现吸烟率为10.97%,女生的现吸烟率为0.20%。54.80%的学生对吸烟或被动吸烟健康危害知识能够完全正确掌握,51.08%的调查对象对三大政策全部赞成。多因素非条件logistic回归结果显示,对学生吸烟现状有影响的因素有性别、母亲文化程度、学习成绩、每月生活费、老师吸烟情况。结论医学院校学生吸烟率相对一般人群低,对烟草控制的知识态度已有一定的基础,但仍相对薄弱,应尽快制定相应措施来改善医学院校学生的吸烟现状并提高其控烟能力。 Objective To understand the smoking status of medical students in Shandong Province and to explore the influencing factors of smoking behaviors of medical students so as to provide the basis for further tobacco control interventions. Methods Two schools were randomly selected from 9 medical schools in Shandong Province. Random stratified cluster sampling was adopted in each school. The professional and grade stratified characteristics were used. The cross-sectional survey method was used to fill in the questionnaire Bearer questionnaire. Using SPSS 13.0 software for data entry and analysis. According to the types of data and the distribution characteristics, the corresponding indexes such as rate and constituent ratio were selected and statistically analyzed. Chi-square test and logistic regression were used for statistical analysis. P <0.05 was considered statistically significant. Results The total smoking prevalence rate was 27.04% and the total current smoking rate was 5.05%. Among them, 10.97% were male and 0.20% were female. 54.80% of the students can get a complete and correct knowledge of the health hazards of smoking or passive smoking, 51.08% of the respondents agree with all three policies. The results of multivariate non-conditional logistic regression showed that the factors influencing students’ current smoking status were gender, mother’s education level, academic record, monthly living expenses and teacher’s smoking status. Conclusions The prevalence of smoking among students in medical colleges is relatively low compared to the general population. The knowledge-based attitudes toward tobacco control have a certain basis, but are still relatively weak. Corresponding measures should be worked out to improve the smoking status of medical students and to improve their tobacco control ability.
