【摘要】 目的探讨吸烟对肺功能的影响。方法通过整群抽样和队列研究方法,对北京、广州城乡35～59岁男女资料完整者7 983人,分吸烟组与不吸烟组进行肺功能调查。结果吸烟组人群的一秒钟用力呼气容积（FEV₁）/身高平方（H²）、用力呼气流量（FEF）/H²及FEV₁/用力肺活量（FVC）均值均低于不吸烟组;男性吸烟各年龄组的FEV₁/H²实测值低于相应的预测值,且2～4年后随访复查时,FEV₁/H²随年龄下降的速度比预测值快;吸烟人群的呼吸道症状和慢性阻塞性肺疾病患病率亦较高。结论说明吸烟对肺功能有害。更多还原

【Abstract】 Objective To analyse the relationship between cigarette smoking and lung function in populations of Beijing and Guangzhou. Methods Complete lung function and smoking habit data were recruited from 7 983 men and women aged 35～59 in or around Beijing and Guangzhou. Comparisons were made between smokers and never smokers. Results The mean values of FEV₁/H², FEF/H² and FEV₁/FVC are all lower in smokers than in never smokers; for male smokers, the observed mean value of FEV₁/H₂ for each age group is smaller than the respective predicted value, and its descending trend with aging is more obvious than the predicted value when re-examination after 2～4 years; furthermore, smokers had higher prevalences of respiratory symptom and COPD. Conelusion Cigarette smoking is harmful to lung function.更多还原
