Aims: To characterize lipid profiles in different type of glucose intolerance, and to assess relationships between serum lipids profile and disturbance of glucose metabolism in prediabetic subjects. Methods: Using the measurements in medical check-up with 75 goral glucose tolerance test (OGTT), total of 620 male subjects, who are not on medications for metabolic diseases or hypertension, were divided into normal fasting glucose and glucose tolerance (NFG/ NGT), isolated impaired fasting glucose (iIFG), isolated impaired glucose tolerance (iIGT) and combined IFG and IGT (IFG/IGT) based on results of the OGTT. Results: Age and body mass index (BMI) were similar in the four groups. Matsuda index (an index of whole body insulin sensitivity) was lower in iIFG, iIGT and IFG/IGT as compared with NFG/NGT. Plasma insulin excursion during the OGTT was significantly higher in IFG/IGT versus NFG/NGT. Serum triglyceride level (TG) and TG to HDL ratio (TG/HDL) were higher in IFG/IGT versus NFG/NGT. Matsuda index was positively correlated with HDL and was inversely correlated with TG, LDL, non-HDL, TG/ HDL and LDL to HDL ratio (LDL/HDL). Backward stepwise multiple regression analysis indicated that increases in BMI, plasma insulin level at 60 min (PI60) and plasma glucose level at 120 min in the OGTT were independently associated with increases in TG and TG/HDL. Increases in BMI and PI60 were related to an increase in non-HDL and LDL/HDL and a decrease in HDL. Conclusions: These results indicate that postprandial hyperglycemia and hyperinsulinemia based on advanced insulin resistance are closely related to lipid risk factors of atherosclerotic macrovascular disease in prediabetic subjects.展开更多
