Abstract:
Objective To investigate abdominal visceral fat area and its relationship with insulin resistance in male patients with type 2 diabetes and normal body mass index (BMI).Methods Seven male patients with type 2 diabetes and normal BMI were divided into two groups according to the abdominal visceral fat area (VFA) measured by CT:visceral obesity group (VFA ≥ 100 cm2) and non-visceral obesity group.Indicators of glucose and lipids metabolism were measured in two groups.Results Among 70 patients 50 (71％) had visceral obesity.In 59 patients who had normal BMI and normal waist circumference (≤90 cm),41 presented visceral obesity (69％).Compared with non-visceral obesity group,the waist circumference,homeostasis model assessment of insulin resistance (HOMA-IR),triglyceride,and VFA were significantly higher in visceral obesity group [(86.4 ± 5.6) vs.(81.2 ± 4.8) cm,t =-2.980,P ＜ 0.01;2.83±2.31 vs.2.01±1.30,t=-2.025,P＜0.05;1.93(1.26-2.79) vs.1.11(0.75-1.46) mmol/L,Z=-3.777,P＜0.01;(143.6 ±31.8)vs.(73.7 ±17.3)cm2,t =-11.456,P＜0.01].Fasting insulin,fasting plasma glucose and glycosylated hemoglobin tended higher in visceral obesity group but not significantly (P ＞ 0.05).Multiple linear regression analysis showed that after adjustment for age and body mass index,abdominal VFA was positively correlated with HOMA-IR (r =0.240,P ＜ 0.05).Conclusion Male type 2 diabetic patients have a high rate of visceral obesity even when their body mass index and waist circumference are normal.Abdominal visceral fat area is closely associated with insulin resistance.
