云南省白族居民吸烟和被动吸烟现状及其对脑卒中患病影响

Prevalence of smoking and secondhand smoke exposure and their effects on stroke among Bai ethnic minority residents in Yunnan province

目的了解云南省白族居民吸烟和被动吸烟现状及其对脑卒中患病的影响,为脑卒中的预防控制提供科学依据。方法于2018年4—5月采用多阶段分层随机抽样方法在云南省大理州剑川县抽取2501名≥35岁白族居民进行问卷调查。结果云南省2501名≥35岁白族居民中,现在吸烟者762人,现在吸烟率为30.5%;被动吸烟者528人,被动吸烟率为21.1%;患脑卒中者155例,脑卒中患病率为6.2%。多因素logistic回归分析结果显示,在控制了性别、年龄、文化程度、年人均收入等混杂因素后,现在吸烟白族居民患脑卒中的风险为非现在吸烟白族居民的3.717倍(OR=3.717,95%CI=1.624~2.231),被动吸烟白族居民患脑卒中的风险为非被动吸烟白族居民的3.690倍(OR=3.690,95%CI=2.562~5.394)。结论云南省白族居民现在吸烟率较高,被动吸烟率较低,吸烟和被动吸烟均可增加脑卒中的患病风险。

Objective To analyze the prevalence of smoking and exposure to secondhand smoke(SHS)and their effects on stoke incidence among Bai ethnic minority residents in Yunnan province and to provide evidences for stroke prevention and control.Methods We conducted a face-to-face questionnaire survey among 2900 Bai ethnic minority permanent adult residents(≥35 years)recruited with stratified multistage random sampling in 9 villages of Jianchuan county,Yunnan province from April to May 2018.Results Among 2501 residents completing the survey,762 were current smokers and the prevalence rate of smoking was 30.5%;528 reported the exposure to SHS and the prevalence rate of SHS exposure was 21.1%;155 were identified suffering from stroke and the prevalence rate of stroke was 6.2%.The results of multivariate logistic regression analysis indicated that after adjusting for sex,age,educational level and annual per capita income,the participants being current smokers had an significantly increased risk of stroke(odds ratio[OR]=3.717,95% confidence interval[95%CI]:1.624-2.231)compared to those being non-smokers;the results also demonstrated that among the participants being nonsmokers,those exposed to SHS had a significantly increased risk of stroke(OR=3.690,95%CI:2.562-5.394)in comparison with the nonsmokers without SHS exposure.Conclusion Among adult Bai ethic minority residents in Yunnan province,the prevalence of current smoking is high but the secondhand smoke exposure rate of nonsmokers is low;both smoking and secondhand smoke exposure could increase risk of stroke in the residents.
