Abstract: ［Abstract］Objective　To observe the clinical indicators，including BMI，blood lipid levels and glycosylated hemoglobin of prediabetic population．Methods　450 subjects including 153 patients with type 2 diabetes mellitus（T2DM），148 people with impaired glucose regulation（IGR）and 149 normal volunteers（NGT）were recruited in the study．All subjects received oral glucose tolerance test．Body mass index（BMI）， waist-to-hipratio（W/H），high density lipoprotein cholesterol（HDL-C）， glycerin three greases（TG）， total cholesterol（TC），low density lipoprotein cholesterol （LDL-C）， and glycosylated hemoglobin（HbA1c） were surveyed．Results（1）Compared with NGT group，people in T2DM or IGR groups showed higher levels of BMI， TG，TC，LDL-C，HbA1c，and lower levels of HDL-C（P＜0.05）．（2）Compared with NGT group，female IGR people showed higher levels of BMI，TG，TC，LDL-C，HbA1C，and lower levels of HDL-C（P＜0.05），however，male IGR people showed higher levels of HbA1c and lower levels of HDL-C（P＜0.05）．（3）Compared with NGT group， IGR people more than 40 years showed lower levels of HDL-C（P＜0.05）．People more than 50 years in IGR group showed higher levels of HbA1c．Conclusions　Lipids disorder as well as adipose play an important role in the progress of impaired glucose tolerance．HbA1c should be mornitored in IGT people regularly.
