目的了解浙江省城市中学生二手烟暴露现状及其影响因素,为制定青少年学生控烟策略提供依据。方法采用分层整群抽样方法,对浙江省11个市的22所学校共计3 799名中学生的二手烟暴露情况进行问卷调查。结果浙江省城市中学生的二手烟暴露率为59.44%,其中男、女生分别为60.59%和56.96%,初、高中生分别为56.89%和60.50%;中学生在家庭、学校遭受二手烟暴露率分别为44.85%和32.28%。中学生周边人群中的吸烟者比例高(父亲为61.54%,教师为34.17%)。Logistic回归分析发现,男生二手烟暴露的危险性为女生的1.18倍;中学生吸烟者二手烟暴露的危险性为非吸烟者的1.96倍;中学生周边人群吸烟都使其二手烟暴露的危险性增加,父母吸烟是非吸烟者的8.56倍、教师吸烟是非吸烟者的2.43倍、同伴吸烟是非吸烟者的1.69倍、其他家人吸烟是非吸烟者的1.19倍;学校教过“拒绝吸烟的技巧”可以减少中学生二手烟暴露的危险性(OR=0.75)。结论浙江省城市中学生二手烟暴露情况严重。控制和减少中学生周边人群吸烟,学校开设控烟健康教育课程,能有效控制中学生烟草暴露。
Objective To understand the status quo of secondhand smoke exposure and its influencing factors in urban middle school students in Zhejiang Province, and to provide basis for formulating the tobacco control strategies for young students. Methods A stratified cluster sampling method was used to survey the secondhand smoke exposure of 3 799 middle school students in 22 schools in 11 cities in Zhejiang province. Results The exposure rate of second-hand smoke in urban middle school students in Zhejiang Province was 59.44%, of which 60.59% and 56.96% respectively in male and female students, 56.89% and 60.50% in junior high and high school respectively. The exposure rates of secondhand smoke to middle school students in families and schools were 44.85% and 32.28%. The proportion of smokers among secondary school students is high (61.54% for fathers and 34.17% for teachers). Logistic regression analysis showed that the risk of secondhand smoke exposure for boys was 1.18 times that of female students; the risk of secondhand smoke exposure for middle school students was 1.96 times that of non-smoker; the smoking among secondary school students increased the risk of secondhand smoke exposure, Parents smoke 8.56 times more than non-smokers, teachers smoke 2.43 times more than non-smokers, fellow smokers are 1.69 times non-smokers, other non-smokers smoke 1.19 times; schools have taught “refusal to smoke skills” can be reduced Secondary school students exposed to the risk of secondhand smoke (OR = 0.75). Conclusion Second-hand smoke exposure in urban middle school students in Zhejiang Province is serious. Control and reduce the smoking in the crowd of middle school students, the school offers tobacco control health education courses, can effectively control high school students tobacco exposure.
