武汉市从不吸烟青少年吸烟易感性

Assessing susceptibility to smoking among non-smoking youth in Wuhan City,China

目的了解武汉市从不吸烟青少年(年龄范围为11~20岁)吸烟易感性以及主要影响因素。方法采用横断面研究设计,运用多阶段分层整群随机抽样方法,于2019年9―11月在武汉市15个行政区所有公立和私立的初中和高中抽取调查对象,对样本数据进行加权处理,采用复杂抽样设计的logistic回归分析模型分析从不吸烟青少年吸烟易感性的影响因素。结果武汉市从不吸烟青少年吸烟易感率为6.2%(95%CI:5.324~7.131),其中男性吸烟易感率为6.8%(95%CI:5.460~8.186),女性吸烟易感率为5.6%(95%CI:4.644~6.489)。多因素logistic回归分析模型分析结果显示,从不吸烟青少年吸烟易感性升高的危险因素包括好朋友吸烟(OR=2.981,95%CI:2.269~3.917,P<0.001)、在学校看到老师吸烟(OR=1.626,95%CI:1.302~2.029,P<0.001)、看见过烟草广告或促销(OR=1.442,95%CI:1.189~1.750,P<0.001)和暴露于二手烟(OR=1.267,95%CI:1.021~1.573,P=0.032);保护因素包括在媒体上看过控烟信息(OR=0.722,95%CI:0.602~0.866,P<0.001)和每周较低可支配收入(1~<20元)(OR=0.690,95%CI:0.487~0.978,P=0.037)。结论应加强媒体控烟宣传教育,全面禁止所有形式的烟草广告、促销和赞助;并在学校实施全面无烟校园政策,开展同伴和教师健康教育以帮助戒烟;尽快通过全面无烟立法,创造无烟环境,以降低青少年吸烟的易感性。

Objective To estimate the susceptibility to smoking among non-smoking youth in Wuhan and identify contributing factors.Methods Using a cross-sectional study design and a multi-stage stratified cluster random sampling method,the participants were selected from all public and private,junior and senior high schools across 15 administrative districts in Wuhan from September to November 2019.The multivariate logistic regression model was used to analyze the smoking susceptibility of non-smoking youth and related factors.Results The prevalence of smoking susceptibility of non-smoking youth in Wuhan was 6.2%(95%CI:5.324-7.131),of which the prevalence of susceptibility of male was 6.8%(95%CI:5.460-8.186),and the prevalence of susceptibility of female was 5.6%(95%CI:4.644-6.489).The multivariate logistic regression analysis showed risk factors for increased susceptibility to smoking in non-smoking youth,which included having good friends who smoke(OR=2.981,95%CI:2.269-3.917,P<0.001),observed teachers smoking at school(OR=1.626,95%CI:1.302-2.029,P<0.001),noticed tobacco advertisements or promotions(OR=1.442,95%CI:1.189-1.750,P<0.001)and exposure to second-hand smoke(OR=1.267,95%CI:1.021-1.573,P=0.032).In contrast,protective factors included seeing anti-smoking media content(OR=0.722,95%CI:0.602-0.866,P<0.001)and a weekly disposable income of 1-<20 yuan(OR=0.690,95%CI:0.487-0.978,􀅰P=0.037).Conclusions It is crucial to enhance media campaigns and education on tobacco control,eliminate all forms of tobacco advertising,promotions,and sponsorships,and implement comprehensive smoke-free campus policies in schools.Health education for peers and teachers on smoking cessation should be provided.Comprehensive smoke-free legislation should be urgently enacted to create a smoke-free environment,thereby reducing the susceptibility of young people to smoking.
