ABSTRACT
To ascertain the relationship between serum leptin levels and related variables [weight, Body Mass Index [BMI] and fat percentage] in a group of Omani obese and non-obese healthy subjects. Leptin levels were assessed in serum samples from 35 obese Omanis and 20 non-obese healthy subjects. There was a significant difference [p< 0.001] in serum leptin between the obese group [34.78 +/- 13.96 ng/ml] and the control non-obese subjects [10.6 +/- 4.2 ng/ml]. Leptin levels were higher in females compared to males. There was a significantly positive correlation between leptin levels in obese subjects with weight [p=0.002], body fat percentage [p=0.0001] and BMI [p=0.001]. We concluded that serum leptin levels are higher in the Omani obese group and correlate positively with body fatness and obesity
