Abstract
To determine firstly whether body fat distribution could predict the presence of atherogenic risk factors better than overall adiposity in Type 2 diabetes, and secondly whether sex differences in these risk factors could be explained by sex differences in fat distribution, waist-to-hip girth ratio (WHR), serum lipids, lipoproteins, apolipoproteins, plasma lipolytic activity, and blood pressure were assessed in 47 patients with Type 2 diabetes, 21 women matched for age, body mass index (BMI) and blood glucose control with 26 men. The men had higher WHR (0.95 (range 0.83-1.07) vs 0.82 (0.74-0.94), p less than 0.001), lower HDL-cholesterol (1.03 +/- 0.05 vs 1.38 +/- 0.06 mmol l-1, p less than 0.001) and apolipoprotein A1 (1.40 +/- 0.06 vs 1.76 +/- 0.06 gl-1, p less than 0.001) concentrations, and higher hepatic lipase activities (16.2 (6.4-38.0) vs 8.6 (2.3-23.1) mmol h-1 l-1, p less than 0.01). In both men and women, BMI and WHR were positively related to serum triglyceride, insulin and C-peptide concentrations. In women, HDL-cholesterol was negatively related to BMI (r = -0.45, p less than 0.05) but only possibly related to WHR (r = -0.33, NS). In men, by contrast, WHR was related negatively to HDL-cholesterol (r = -0.60, p less than 0.005), HDL2-cholesterol (r = -0.43, p less than 0.05), and apolipoprotein A1 (r = -0.70, p less than 0.001) and positively to hepatic lipase activity (r = 0.65, p less than 0.001), whereas the same relationships with BMI were not significant.(ABSTRACT TRUNCATED AT 250 WORDS)
