体质指数、腰围和腰臀比与糖代谢的相关性研究

目的探讨蒙古族居民体质指数（BMI）、腰围（WC）和腰臀比（WHR）与糖代谢的相关性。方法选择内蒙古科左后旗朝鲁吐乡和奈曼固日班花乡的32个行政村,对20岁以上居民进行调查。采用面对面调查方式,收集人口学特征资料以及吸烟、饮酒等生活方式,测量血压、身高、体质量、腰围和臀围。采集血标本,检测血糖、血脂、C-反应蛋白等指标的水平。采用多因素Logistic回归评估3个肥胖指标与糖尿病发生的关系。结果共调查2 589人,糖尿病和空腹血糖受损的总检出率分别为3.7%（男3.9%,女3.5%）、18.5%（男17.7%,女19.0%）。多因素Logistic回归分析显示：在男性中,WHR升高者患糖尿病的OR值为2.120（P〈0.05）,BMI和WC升高者患空腹血糖受损的OR值分别为1.624和1.472（均P〈0.05）;在女性中,WC升高者患糖尿病的OR值为2.336（P〈0.01）。结论在男性中,WHR升高可能是糖尿病的危险因素;BMI和WC升高可能是空腹血糖受损的危险因素。在女性中,WC升高可能是糖尿病的危险因素。

Study on the relationship between body mass index,waist circumference,waist to hip ratio and glucose metabolism

Objective To explore the relationship between body mass index（BMI）,waist circumference（WC）,waist to hip ratio（WHR） and glucose metabolism.Methods Total 32 villages in Kezuohou Banner and Naiman in Inner Mongolia were selected as study field and residents aged 20 and above were served as study subjects,demographic data and life style including cigarette smoking and alcohol intake were investigated by face to face method.Their blood pressure,height,body weight,waist and hip circumference,were measured by standardized methods.Their blood samples were collected and fasting plasma glucose level,blood lipids and C-reactive protein were examined for all subjects.Multivariate Logistic regression analysis was used to evaluate relations between the three obesity indexes and diabetes mellitus（DM）.Results Total 2 589 Mongolians aged 20 years or above were recruited as study subjects.The overall prevalence of diabetes and IFG was 3.7%（males 3.9%;females 3.5%）and 18.5%（males 17.7%;females 19.0%）,respectively.The Multivariate logistic regression analysis showed that diabetes was significantly associated with high WHR（odds ratio：2.120）.IFG was significantly associated with high BMI（odds ratio：1.624） and high WC（odds ratio：1.472） in male;In female,diabetes was significantly associated with high WC（odds ratio：2.336）.Conclusions In male,WHR may be a risk factor for DM;BMI and WC may be risk factors for IFG.In female,WC may be the risk factor for DM.
