To analyse the relationship between cigarette smoking and lung function in populations of Beijing and Guangzhou.
Complete lung function and smoking habit data were recruited from 7983 men and women aged 35-59 in or around Beijing and Guangzhou. Comparisons were made between smokers and never smokers.
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 in 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.
Cigarette smoking is harmful to lung function.
分析北京和广州人群中吸烟与肺功能之间的关系。
收集了来自北京及周边和广州地区7983名35 - 59岁男性和女性的完整肺功能及吸烟习惯数据。对吸烟者和从不吸烟者进行了比较。
男性吸烟者中，吸烟者的FEV1/H2、FEF/H2和FEV1/FVC的平均值均低于从不吸烟者；各年龄组吸烟者的FEV1/H2实测平均值均小于各自的预测值，且在2 - 4年后复查时其随年龄增长的下降趋势比预测值更为明显；此外，吸烟者呼吸道症状和慢性阻塞性肺疾病（COPD）的患病率更高。
吸烟对肺功能有害。
