中国维吾尔族、汉族、哈萨克族成人不同腰围切点代谢综合征患病率的研究

目的 调查分析我国维吾尔族、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,初步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吾尔族、汉族、哈萨克族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≥90 cm,女≥80cm时,维吾尔族、汉族、哈萨克族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≥89 cm;汉族男≥85 cm,女≥80 cm;哈萨克族男≥99 cm,女≥88cm,维吾尔族、汉族、哈萨克族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.应该根据民族异质性确定适合不同民族的MS腰围切点.对各民族MS进行客观、公正地评估,有针对性地开展健康教育活动及疾病预防控制会起到一定的指导作用.

The different cut-off point of waist circumference for influencing on prevalence of metabolic syndrome inChinese Uygur, Han and Kazak adults

Objective To investigate and analyse the prevalence of the metabolic syndrome（MS） in Chinese Uygur, Han and Kazak adults using the criteria of different cut-off point of waist circumference. Methods A cress- sectional study was conducted in Xinjiang Urumqi city, Hetian and Ahay region with a representative sample of Chinese Uygur,Han and Kazak adults from 20 to 74 years of age. The sample was randomly selected using stratified cluster sampling. Results Diagnosed by using cut-off point of waist cireumference≥90 cm in male and ≥80 cm in female for all subjects, the crude prevalence of MS was 42. 1%, 16.7% and 9. 5% in Uygur, Han and Kazak respectively. When the cut-off point of waist circumference was adjusted to ≥93 cm and ≥89 cm in Uygur male and female,to ≥85 cm and ≥80 cm in Han male and female and to ≥99 cm and ≥88 cm in Kazak male and female, the crude prevalence was 25.6%, 20. 3% and 6. 9% and the age adjusted prevalence was 17. 6%, 13.4% and 4. 5% in Uygur, han and Kazak respectively. Conclusions Adjusting the cut-off point of waist circumference according to national characteristics will decrease the misdiagnosis of the prevalence of MS in Uygur and Kazak and the missed diagnosis of it in Han.
