They were subjected to full history taking, clinical examination, assessment of weight, height, and BMI Serum leptin was measured by ELISA technique, Fasting, and two hours post prandial Blood glucose and serum insulin level were measured. Our results show: serum leptin level was insingnificantly lower in males than females, there was significant positive correlations between leptin level and body weight and BMI. positive correlation between serum leptin and serum insulin levels. But no significant correlations was found between serum leptin and Blood glucose level
