Abstract: Background　It is estimated that increasing prevalence of metabolic syndrome （MS） will cause a heavy disease burden in the future.Studies have shown that the incidence of cardiovascular events in patients with metabolic syndrome is 5.5 times higher than that in those without MS during a 5-year follow-up.Therefore，intensive studying the risk factors of MS in a given area is conducive to improving the overall quality of life of the area.Objective　To explore the prevalence and influencing factors of MS among Kazakh herdsmen in Xinjiang pastoral area.Methods　In this cross-sectional study，by use of multistage clustered and stratified random sampling，7 453（≥18 years old） Kazakh herdsmen in Xinjiang pastoral area were recruited during January to October 2018.They received a questionnaire survey，a physical examination and a laboratory test.The age-specific prevalence of MS in this group was standardized in accordance with that of age-matched norm population collected from China's Sixth National Population Census held in 2010，influencing factors of MS among Kazakh herdsmen in Xinjiang pastoral area were discussed.Results　Among the participants，the prevalence rate of MS was 35.11% and the standardized prevalence rate was 33.46%.The trend chi-square test showed that the prevalence of MS increased with BMI increasing （χ2ttrend=1 485 436，P<0.05）.By fitting regression curves for age and the number of MS components，we found that the number of MS components also increased with age increasing，so the derived fitting equation was：y=0.333+0.029x，R2=0.61.After adjusting 3 confounding factors including age，BMI，and education level，multivariate unconditional logistic regression analysis showed that female，meat-rich diet，salt tooth，fatty tooth，smoking，frequent drinking，daily drinking，occasional exercise，no exercise，familial history of hypertension and familial history of coronary heart disease were influencing factors for MS（P<0.05）.Conclusion　The prevalence of MS was high among Kazakh herdsmen in Xinjiang pastoral area，which was mainly influenced by gender，meat and vegetable collocation，salt tooth，fatty tooth，smoking，drinking，physical exercise，familial history of hypertension and familial history of coronary heart disease.

摘要： 背景　随着代谢综合征（MS）的患病率日趋增高，预计未来MS将造成十分沉重的疾病负担。有研究显示，对MS患者随访5年发现其心血管事件发生率较无MS患者增高5.5倍。因此，深入研究MS的影响因素，有利于提高患者的生活质量。目的　调查新疆牧区哈萨克族牧民MS患病率并探讨其影响因素。方法　2018年1—10月采用多阶段分层整群随机抽样的方法，对≥18岁的7 453例新疆牧区哈萨克族牧民进行问卷调查、体格检查和实验室检测。采用2010年第六次人口普查年龄结构对MS患病率进行标化，探讨新疆牧区哈萨克族牧民MS患病的影响因素。结果　新疆牧区哈萨克族牧民MS患病率为35.11%，标化患病率为33.46%；随着BMI增大，MS患病率增高（χ2趋势=1 485.436，P<0.05）；通过对年龄和MS组分个数做拟合回归曲线，结果显示，随年龄增长MS组分个数随之增多，拟合方程为y=0.333+0.029x，拟合优度指数R2=0.61；在控制了年龄、BMI、文化程度后，多因素非条件Logistic回归分析显示：女性、饮食习惯荤食为主、嗜盐、嗜油、吸烟、经常喝酒、每天喝酒、偶尔锻炼、不锻炼、高血压家族史、冠心病家族史是新疆牧区哈萨克族牧民MS患病的影响因素（P<0.05）。结论　新疆牧区哈萨克族牧民MS患病率较高，性别、荤素搭配、嗜盐、嗜油、吸烟情况、喝酒情况、体育锻炼、高血压家族史、冠心病家族史是新疆牧区哈萨克族牧民MS患病的主要影响因素。
