Note: Values are presented as the mean ± SD for variables with normal distribution or median (interquartile) for variables without normal distribution. BMI: body Mass Index, WC: waist circumference, TG: triglycerides, TC: total cholesterol, HDL-C: high density lipoprotein, LDL-C: low density lipoprotein, FBS: fasting blood sugar. * P-value was obtained by the independent t test and P < 0.05 was considered as statistically significant
