宁夏地区睡眠呼吸暂停低通气综合征的流行问卷调查

Prevalence of sleep apnea-hypopnea syndrome in Ningxia

目的了解宁夏地区睡眠呼吸暂停低通气综合征(SAHS)的患病情况,为进一步制定该病的防控措施提供基线资料。方法采取多级整群分层抽样方法,2007年6月至2008年12月对宁夏地区银川市、石嘴山市、吴忠和泾源城乡20岁以上常住居民10 000人进行调查问卷,内容包括打鼾情况、日间嗜睡程度(ESS嗜睡量表),测量身高、体重、颈围、腹围等数据,初步得出宁夏地区SAHS的患病情况。结果有效问卷7804份(有效率91.64%),回族3914人(50.15%),汉族3890人(49.85%)。依据中、重度打鼾结合日间嗜睡(ESS≥9)为标准,初步保守估计宁夏地区20岁以上常住居民SAHS的患病率为3.31%,其中汉族SAHS的患病率为2.93%,回族为3.68%,两民族之间的患病率差异无统计学意义。城镇人群SAHS的患病率为4.23%,农村为2.80%,城镇和农村患病率差异有统计学意义,且随着体重指数的增加SAHS患病率明显增加。结论宁夏地区汉族SAHS的患病率为2.93%,回族SAHS的患病率为3.68%,且存在地区差异,表现为城镇人群SAHS的患病率明显高于农村。

Objective To investigate the prevalence of sleep apnea-hypopnea syndrome （SAHS）in Ningxia, and to provide the basic data for treatment and prevention of the disorder. Methods Totally 10 000 subjects（ aged t〉20） were selected by multistage stratified cluster sampling of the general population living in Ningxia. The questionnaire concerning snoring, daytime sleepiness （Epworth Sleepiness Scale ESS）was comlpeted and the height, weight, neck circumference and abdomen circumference were measured. The prevalence of SAHS was estiminated from the results. Results A total of 8516 subjects （85.16%） had answered the questions, and 7804 （91.64%） were available for evaluation, including Hui nation ality 3914 （50. 15% ） ,Han nation ality 3890 （49.85%）. According to moderate/severe snoring and excessive daytime sleepiness （ ESS ≥9 ） criteria, the prevalence of SAHS was 3.31% in Ningxia. The prevalence of SAHS was 2. 93% in han nationality and 3. 68% in Hui nationality. The prevalence of SAHS was 4. 23% in towns and 2. 80% in the rural areas （ P 〈 0. 05 ）. Besides, the increase in body mass index can predispose the prevalence of SAHS. Conclusion In Ningxia,the prevalence of SAHS is 2. 93% in Han nationality and 3.68% in Hui nationality. The prevalence of SAHS is higher in towns than in rural areas.
