目的了解西藏初中学生烟草广告和促销暴露现状,为制定相应控烟措施提供参考。方法采用全球青少年烟草调查(GYTS)问卷,多阶段分层整群随机抽取西藏3 652名初中学生进行问卷调查。结果西藏初中学生烟草广告和促销暴露率为83.54%。单因素分析结果,不同性别、城乡、零花钱、父母吸烟情况和朋友吸烟情况的学生烟草广告和促销暴露率差异均有统计学意义(χ~2值分别为41.118,28.782,19.558,51.211,75.095,P值均<0.01)。非条件Logistic回归分析结果显示,男性、城市学生、零花钱>50元、父母亲都吸烟或仅父亲吸烟、多数朋友吸烟等因素是西藏初中学生烟草广告和促销暴露的危险因素(OR值分别为0.559,0.417,2.249,6.076,1.494,2.717,P值均<0.01);烟草广告和促销暴露组学生的吸烟率和尝试吸烟率分别是非暴露组的3.45,2.94倍(χ~2值分别为56.145,72.822,P值均<0.01)。结论西藏初中学生烟草广告和促销暴露情况较为严重。烟草广告和促销暴露能明显提高西藏初中学生吸烟率和尝试吸烟率,应多方面共同努力,营造无烟社会氛围。
Objective To understand the present situation of tobacco advertising and promotion exposure among middle school students in Tibet and provide references for formulating corresponding tobacco control measures. Methods A total of 3 652 middle school students in Tibet were randomly selected from the GYTS questionnaire and multi-stage stratified cluster questionnaire. Results Tibet junior high school students tobacco advertising and promotional exposure rate was 83.54%. The results of univariate analysis showed that there were significant differences in the exposure rates of tobacco advertising and promotion among students with different gender, urban and rural areas, pocket money, parents ’smoking and friends’ smoking (χ ~ 2 values were 41.118,28.782,19.558,51.211,75.095 respectively , P <0.01). Non-conditional logistic regression analysis showed that men, urban students, spending more than 50 yuan, smoking parents or fathers only, most friends smoking and other factors is a risk factor for tobacco advertising and promotional exposure in Tibet junior high school students (OR values were 0.559,0.417,2.249,6.076,1.494,2.717, P <0.01). The smoking rate and smoking prevalence of students in tobacco advertisement and promotion exposure groups were 3.45 and 2.94 times higher than those in non-exposure group (χ ~ 2 values were 56.145 , 72.822, P <0.01). Conclusion Tibetan junior high school students tobacco advertising and promotional exposure is more serious. Tobacco advertising and promotion of exposure can significantly improve the smoking rate and smoking prevalence of middle school students in Tibet.
