The association between the lipid profile and fasting blood glucose with weight related outcomes in healthy obese adults

Abstract

Objectives: The present study was conducted on healthy obese persons to determine: (i) the association between total cholesterol, triglycerides, HDL cholesterol, total cholesterol/HDL ratio and fasting blood glucose (FBG) with (a) BMI, (b) waist circumference (WC) and (c) body fat and (ii) the presence of undiagnosed type 2 diabetes (based on fasting blood glucose) in the participants. There were 1140 participants of both sexes (female:male 697:443; group mean age 44.0 ± 10.8 years; BMI ≥ 25 kg/m2) from four regions of India. The participants were assessed for (i) BMI and WC, (ii) body fat, (iii) fasting serum lipid profile and (iv) FBG. Statistical significance (α) was set at 0.05. Results: Based on a linear regression analysis triglycerides acted as a significant predictor for body fat. Triglycerides showed a significant negative correlation with BMI and body fat. HDL cholesterol was significantly negatively correlated with waist circumference and positively correlated with body fat. Total cholesterol/HDL ratio was positively correlated with waist circumference and negatively correlated with body fat. A significant positive correlation of FBG and waist circumference was also observed. Among the healthy participants 34.2% had pre-diabetes and 13.6% had diabetes.
