目的调查长春市20岁以上居民阻塞性睡眠呼吸暂停低通气综合征（OSAHS）的患病状况，为该病的防治提供依据。方法采用分层整群随机抽样的方法，选择长春市朝阳区和绿园区部分20岁以上常驻居民3960名为调查对象，进行入户调查，从打鼾≥2级者中随机抽样200名，行整夜睡眠呼吸监测，估算人群OSAHS的患病状况。结果有效问卷3648份（有效率97．64％），≥2级打鼾为31．00％，男性（40．07％）高于女性（21．76％）；不同职业中，司机组最高（42．47％）。以睡眠呼吸暂停低通气指数（AHI）≥5次／h加Epworth嗜睡量表（ESS）评分≥9分、夜间最低血氧饱和度〈90％为标准，估算人群OSAHS的患病率为4．81％。结论长春市20岁以上人群OSAHS的患病率为4.81％，人们对打鼾和OSAHS的发生尚未引起足够的重视，应加强宣传教育工作。

The prevalence of obstructive sleep apnea-hypopnea syndrome in adults aged over 20 years in Changchun city

OBJECTIVE: To investigate the prevalence of obstructive sleep apnea-hypopnea syndrome (OSAHS) in adults aged over 20 years in Changchun city, providing epidemiological data for treatment and prevention of the disease. METHODS: 3,960 subjects were derived from a stratified cluster and random sampling of the population in two districts of Changchun city. They were asked to answer the questions from a questionnaire in their houses. According to the degree of snoring, 200 subjects with a snoring score >or= 2 degree were selected to undergo polysomnography for a whole night and the prevalence of the disease was estimated. RESULTS: A total of 3,648 (97.64%) validated questionnaires was collected. Of them 31.00% had a snoring score >or= 2 degree, the prevalence was higher in males (40.07%) than in females (21.76%). The prevalence of snoring was higher in drivers (42.47%) than in other occupations. The estimated prevalence of OSAHS defined by apnea-hypopnea index (AHI) >or= 5, Epworth sleepiness scale (ESS) >or= 9 and arterial oxygen saturation (SaO(2)) < 90% was 4.81%. CONCLUSIONS: The estimated prevalence of OSAHS in adults aged over 20 years in Changchun city was 4.81%. Doctors should pay more attention to the disease and the ordinary people should be informed of the health impact of snoring and OSAHS.
