中国维、汉、哈族成人不同腰围切点代谢综合征的患病率

目的分析我国维吾尔族、汉族及哈萨克族成人不同腰围切点下的代谢综合征（Ms）患病率，探讨不同民族采用适合本民族特点的腰围切点诊断MS的可行性。方法采用分层整群随机抽样方法，对新疆乌鲁木齐市、和田地区及阿勒泰地区维、汉、哈族20～74岁人群进行MS横断面调查。MS诊断以国际糖尿病联盟（IDF）定义为基础，腰围切点根据不同民族区分。结果当腰围切点均为男≥90em和女≥80cm时，维、汉、哈族MS粗患病率分别为42．1％，16．7％和9．5％；年龄标化患病率分别为28．3％，10．5％和5．9％。调整腰围切点为维吾尔族男≥93cm，女I〉89cm；汉族男I〉85cnl，女I〉80cm；哈萨克族男≥99cm，女≥88cm，维、汉、哈族MS粗患病率分别为25．6％，20-3％和6．9％；标化患病率分别为17．6％，13．4％和4．5％。结论根据各民族自身特点调整腰围切点可减少维吾尔族和哈萨克族MS的误诊率，减少汉族MS的漏诊率，维吾尔族与汉族和哈萨克族之间的MS患病率差距缩小。

Prevalence of metabolic syndrome using various cut-off points of waist circumference in Chinese Uygur,Han and Kazak adults

Objective To investigate the prevalence of metabolic syndrome （MS） in Chinese Uygur, Han and Kazak adults by using various cut-off points of waist circumference, and to determine the feasibility of applying cut-off points on an ethnic basis. Methods A randomized cross-sectional study was performed based on stratified cluster sampling among Chinese Uygur, Han and Kazak adults of 20 to 74 years old in Xinjiang Urumqi city, Hetian and Altay regions. The diagnosis of MS took reference on the definition of International Diabetes Federation （IDF）, and the cut-off points of waist circumference were stratified on the ethnic basis. Results The cut-off points of waist circumference I〉 90 cm in males and ≥ 80 cm in females yielded an overall prevalence of MS were 42.1%, 16.7% and 9.5%, and this figure was 28.3%, 10.5% and 5.9% for age-adjusted prevalence in Uygur, Han and Kazak adults, respectively. When the cut-off points were adjusted to ≥93 cm and ≥89 cm in Uygur males and females, ≥85 cm and ≥80 cm in Han males and females and to 〉199 cm and ≥88 cm in Kazak males and females, an overall prevalence of 25.6%, 20.3% and 6.9% and age-adjusted prevalence of 17.6%, 13.4% and 4.5% in Uygur, Han and Kazak adults were revealed, respectively. Conclusions Adjusting the cut-off point of waist circumference, based on ethnic characteristics, may reduce the misdiagnosis of prevalence of MS in Uygur and Kazak adults and the missed diagnosis rate in Han adults. This may also contribute to reduced gap between the prevalence of MS among Uygur, Kazak and Han adults.
