居民二手烟暴露与控烟权利执行意愿关联性分析

Prevalence of secondhand smoke exposure and willingness to implement smoke-free regulation among residents in Guangzhou city

目的了解广东省广州市居民二手烟暴露情况,探讨二手烟暴露程度与控烟权利执行意愿的关联性。方法采用多阶段分层随机抽样方法,对广州市5 135名≥15岁居民进行问卷调查,比较不同人口学特征居民二手烟暴露率,并对有统计学关联的二手烟暴露程度和控烟权利执行意愿进行关联性分析。结果不吸烟者4 239人,男性占48.98%;二手烟暴露率为46.99%,男性二手烟暴露率（48.95%）高于女性（45.98%）,暴露率高中/中专学历者（55.72%）和企业职员（54.34%）较高,≥65岁组（28.51%）和离异/分居/丧偶者（23.60%）较低;二手烟暴露与控烟权利执行意愿有关联,与二手烟危害知识无关联;对应分析结果显示,知晓并会执行控烟权利与无二手烟暴露相关联;知晓但不会执行控烟权利与二手烟暴露1~3d/周相关联;不知晓控烟权利与二手烟暴露4~7d/周相关联。结论居民有执行控烟权利意愿能减少二手烟暴露,在控烟工作中应加强控烟权利宣传。

Objective To describe the prevalence of secondhand smoke（SHS）exposure among residents in Guangzhou city and to explore the association between SHS exposure and willingness to implement smoke-free regulation.Methods A cross-sectional survey was conducted in Guangzhou city using stratified multi-stage cluster sampling design.Totally 5 135 residents aged≥15 years were administered a face-to-face interview and SHS exposure status in the residents of different demographical characteristics were compared.Correspondence analysis was used to examine the relationship between SHS exposure and willingness to implement smoke-free regulation.Results Among the 4 239 non-smokers,48.98% were male.SHS exposure was reported by 46.99% of respondents and the males were more likely to report exposure to SHS compared to the females（48.95% versus 45.98%,P〉0.05）.Participants with high school/technical secondary school or higher education（55.72%）and enterprise employees（54.34%）had significantly higher SHS exposure rate,while respondents aged65 years and older（28.51%）and divorced/separated/widowed persons（23.60%）had significantly lower SHS exposure rate.SHS exposure was significantly associated with the awareness of smoke-free regulation and the willingness to implement the regulation.There was no significant association between SHS exposure and knowledge about smoking hazards.Correspondence analysis showed that awareness of and willingness to implement smoke-free regulation were related to without SHS exposure,but unwillingness to implement smoke-free regulation was related to SHS exposure of 1-3days/week and the unawareness of smoke-free regulation was related to SHS exposure of 4-7 days/week.Conclusion Residents having willingness to implement smoke-free regucation might have less SHS exposure.Propaganda should be strengthened for smoke-free regulation in tobacco control.
