  • Title: Relationships of obesity indices to serum insulin and lipoproteins in relatives of black patients with noninsulin-dependent diabetes mellitus (NIDDM).
    Author: Osei K, Cottrell DA, Bossetti B.
    Journal: Int J Obes; 1991 Jul; 15(7):441-51. PubMed ID: 1894421.
    Abstract:
    We have examined the relationships between obesity indices and various metabolic parameters in seven obese (body mass index (BMI) mean +/- s.e.m. 42 +/- 2.5 kg/m2), ten nonobese (BMI 25.3 +/- 1.2 kg/m2) nondiabetic female relatives of black patients with NIDDM and eight healthy controls (BMI 24.5 +/- 1.1 kg/m2). Despite the greater BMI in the obese relatives, percent body fat was not different from that of the nonobese relatives (38 +/- 2 vs 34 +/- 3 percent). Both values were, however, significantly (P less than 0.05) greater than that of the healthy controls (25 +/- 3 percent). Mean waist-to-hip circumference ratio (WHR) was greatest in obese relatives (0.89 +/- 0.01), intermediate in nonobese relatives (0.83 +/- 0.01) and least in the healthy controls (0.77 +/- 0.04). Mean sum of skinfold thickness from biceps, triceps and subscapular (SS) region was also greatest in obese relatives, intermediate in nonobese relatives and least in controls. Centrality index was not, however, different among the groups. Mean fasting serum glucose levels were slightly higher but not significantly different in the relatives compared to controls (obese 82 +/- 3; nonobese 81 +/- 4; controls 75 +/- 3 mg/dl). Following oral glucose ingestion, serum glucose rose to significantly (P less than 0.05) greater levels at 30, 60 and 90 min in the relative subgroups vs controls. Mean fasting and post-prandial peak serum insulin concentrations were significantly (P less than 0.05-0.01) greater in both relative subgroups vs controls. While mean serum glucose profiles and glucose disappearance decay (KG) following intravenous glucose load were identical in the relatives and controls, serum insulin responses were significantly greater in the relatives. The mean basal and post-stimulation serum C-peptide concentrations were similar in all the three groups, irrespective of the stimulus; thus suggesting a reduced hepatic insulin extraction in the relatives. Fasting serum cholesterol, triglyceride, high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) as well as FFA levels were not different between the relatives and controls despite the hyperinsulinemia in the former group. WHR correlated with basal insulin in the relatives (r = 0.416, P less than 0.05) and controls (r = 0.68, P less than 0.01) but not with stimulated insulin, lipids and lipoproteins in any of the groups. In contrast, both percent BFM and SS thickness correlated significantly (P less than 0.001) with post-glucose insulin concentrations in the relatives only.(ABSTRACT TRUNCATED AT 400 WORDS)
