目的了解开封市某城区学生烟草流行行为状况和相关影响因素,为制定学生控烟策略提供依据。方法采用分层整群抽样的方法,对开封市某城区9所学校27个班级共计1 546名学生的二手烟暴露情况进行问卷调查。结果开封市某城区学生尝试吸烟率为11.06%,现吸烟率为8.15%;二手烟暴露率为56.21%,其中男、女生二手烟暴露率分别为63.04%和49.22%,差异有统计学意义(χ~2=19.995,P<0.05)。多因素非条件Logistic回归分析结果显示,父母吸烟(OR=12.425)、教师吸烟(OR=2.429)、朋友吸烟(OR=2.017)、年龄>14岁(OR=1.873)等增加了学生二手烟暴露的危险性;学校开设控烟健康教育课降低了学生二手烟暴露的危险性(P值均<0.01)。结论开封市某城区学生吸烟和二手烟暴露率较高。父母、老师、朋友等吸烟是二手烟暴露的主要因素,学校健康教育可以减少学生二手烟暴露的危险性。
Objective To understand the prevalence of tobacco epidemic among students in a city of Kaifeng and its related factors, and to provide evidence for the development of tobacco control strategies. Methods A stratified cluster sampling method was used to investigate the secondhand smoke exposure of a total of 1 546 students from 27 classes in 9 schools in a city of Kaifeng. Results The smoking rate of students in a city of Kaifeng City was 11.06%, and the current smoking rate was 8.15%. The exposure rate of secondhand smoke was 56.21%. The exposure rates of secondhand smoke were 63.04% and 49.22% respectively in male and female students, the difference was statistically significant χ ~ 2 = 19.995, P <0.05). Multivariate non-conditional logistic regression analysis showed that smoking of parents (OR = 12.425), teacher smoking (OR = 2.429), friend smoking (OR = 2.017) and age> 14 years (OR = 1.873) The risk control of smoking health education classes in schools reduced the risk of secondhand smoke exposure (P <0.01). Conclusion There is a high rate of smoking and secondhand smoke in a city in Kaifeng City. Smoking, such as parents, teachers and friends, is a major factor in exposure to secondhand smoke. School health education can reduce the risk of secondhand smoke exposure.
