Popis: Objective To compare the changes in body composition, including fat mass index (FMI) and fat free mass index (FFMI) during puberty development of obese and normal-weight children in China, and to explore the effect of age and gender on body composition. Methods A total of 356 children at the age of 7-15 years were enrolled in this study. Body composition of 10 normal-weight and obese children in each age group was measured by dual-energy x-ray absorptiometry (DEXA). FFMI and FMI were calculated according to the following formula: FFMI (kg·m -2 )= FFM(kg) / height 2 (m 2 ) and FMI (kg·m -2 )= FM (kg) / height 2 (m 2 ). Results The fat mass and fat free mass of obese children were significantly higher than those of normal-weight children (P
