To compare metabolic status of lean vs overweight/ obese type 2 diabetes mellitus (T2DM) patients and correlate biochemical parameters with anthropometric measures.
Materials and methods
A total of 100 T2DM patients were categorized as lean and overweight/obese according to body mass index (BMI); 50 age- and sex-matched healthy controls were selected. Anthropometric measures of BMI, waist circumference (WC), and waist:hip (W:H) were recorded. Fasting blood samples were assayed for fasting plasma glucose (FPG), serum total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL), and nonesterified free fatty acids (NEFA). Low-density lipoprotein (LDL) was calculated by Friedewald's formula and TG: HDL was measured as measure of insulin resistance (IR).
Anthropometric measures of overall (BMI 31.65 ± 5.49, 20.34 ± 2.45 vs 22.29 ± 3.21) and visceral adiposity (WC 91.98 ± 6.8, 75.45 ± 4.34 vs 74.19 ± 3.98 and W:H 0.99 ± 0.12, 0.78 ± 0.21 vs 0.76 ± 0.32) were significantly higher in overweight/ obese (p < 0.05) compared with lean T2DM and controls. Total cholesterol, TG, LDL, and NEFA were significantly raised and HDL decreased in T2DM compared with those of controls. But much higher values were observed in overweight/obese than in lean group. Triglycerides: HDL was significantly higher in obese than in lean patients (4.66 ± 1.89 vs 7.91 ± 3.01), confirming significantly decreased insulin sensitivity among obese than non-obese diabetics. Positive correlation was observed between BMI, WC, W:H and TC, TG, LDL, NEFA, and TG:HDL, while negative correlation was observed with HDL in obese group. Lean individuals with normal BMI, WC had deranged lipids with IR.
Lean and obese T2DM have dyslipidemia and IR. Poor metabolic profile is associated with overall and visceral adiposity in obese and not in lean T2DM individuals.
