ABSTRACT
Objective: To study the dietary habits and serum leptin levels of obese children and its possible association to lipids and glucose metabolism, serum lipids and C peptide (CP) in children with different body weight. Methods: 52 obese children were inquired about their favorite foods and food intake. 145 healthy children (85 boys, 60 girls), aged 6-13, with a wide range of body mass index (BMI) 14 to 30 kg/m 2, were measured for fasting serum leptin, CP, glucose, lipids (TG, TC, LDL C,HDL C), height and weight. The children were classified into three groups by BMI, i.e. normal weight group (A group), overweight and slight obese group (B group). moderate and severe obese group (C group). Results: 65% of obese children liked meat best. 38.46% of them ate most in supper. The serum leptin, CP, TG in obese children were higher than that in normal children. Leptin concentration of girls were higher than that in boys in A and B groups (P
