目的：探讨肺通气功能与年龄分层的相关性，以及社区居民肺通气功能测试普查的意义。方法随机抽取崇明县多个社区、自然村居民，进行肺通气测定、COPD相关症状和有害气体接触史的问卷调查。结果共调查3842位居民，符合COPD诊断标准共378例，总患病率为9.8%，其中否认有呼吸道症状和COPD危险因素(有害气体接触史，包括主动吸烟、被动吸烟、接触生物燃料、职业有害气体接触史等)92例(24.3%)。随着年龄的增加，肺功能测试者的通气功能呈下降趋势且具有统计学意义(P<0．05)。结论成年人FEV1/FVC随着年龄的增加而下降，以FEV1/FVC<0.7作为COPD的诊断标准，对既无症状又无有害气体接触史的居民进行普查有COPD过度诊断的风险。

Objective To survey the correlation between lung ventilation function and age, and the signifi-cance of lung function census. Methods 3842 respondents were given a questionnaire survey in Chongming county of Shanghai, which included determination of pulmonary ventilation, symptoms related to COPD and contact history to harmful gas. Results There were 278 cases of COPD, and the total prevalence was 9. 8%, which included 92 COPD patients (24. 3%) had neither respiratory symptoms nor risk factors of COPD such as smoking, passive smok-ing, using biomass fuels etc. With the increase of age, the lung ventilation function declined significantly ( P <0. 05). Conclusion FEV1/FVC declines with the increase of age in adults, so there are risks of excessive diagnosis of COPD with the criteria diagnosis (FEV1/FVC<0. 7), especially for the people who have no symptoms or contact with harmful gas.
