糖尿病与肥胖关系

目的：探讨2型糖尿病与肥胖的关系。方法：根据1985年WHO糖尿病诊断标准，11650糖耐量正常（NGT）、糖耐量低减（IGT）和糖尿病（DM）人群的肥胖情况进行研究，结果我省肥胖（BMI≥27）患病率为7．9％，BMI大于25，少于30人群，DM和IGT患病率是正常体重的倍和2．5倍。Logistic回归分析提示年龄、体重指数、腰臂围比均是IGT，DM患病的独立危险因素，结论：体重指数增加可增加糖尿病患病率。

Relationship between type 2 diabetes mellitus and obesity

Objective　To study the reationship between obesity and type 2 diabetes mellitus. Methods　According to WHO (1985) criteria of diabetes mellitus and impaired glucose tolerance, 11 650 residents aged from 20 to 70 years and in over 14 areas of Guangdong Province were surveyed. Results　The prevalence of obesity (body mass index ≥27) were 7.9%. The prevalences of diabetes and IGT in the population whose BMI ranging 25～30 were 3 and 2.5 times higher than the normal BMI subjects respectively. Multiple logistic regression analysis showed that age, body mass index and the waist to hip ratio (WHR) were independent risk factors of type 2 diabetes mellitus. Conclusion　Increased body mass index was significantly associated with higher prevalence of type 2 diabetes mellitus.
