Background. Body mass index (BMI) does not allow to discriminate the composition of the different body compartments. The aim of this study is to elaborate reference values of the fat mass index (FMI) and fat-free mass index (FFMI) in healthy adolescents using anthropometric techniques in order to be available as reference standards in daily clinical practice.
Methods. Transversal study in 940 healthy Caucasian adolescents (370 males and 570 females), aged 10.1 to 14.9 years. Weight, height and skinfold thickness were registered, and BMI, percentage of total boy fat, FMI and FFMI, and FMI and FFMI percentiles were calculated.
Results. In males a significant increase in the FFMI is observed, and the percentage of total body fat and FMI significantly decreased. In contrast, in females the percentage of body fat mass, FMI and FFMI significantly increased. Except for the 10 years, FMI was higher (p<0.05) in females in all ages. FFMI was higher (p<0.05) in males in all ages. FFMI and FMI percentiles for healthy adolescents (both sexes) categorized by age are displayed.
Conclusions. Reference values of FMI and FFMI would be a very useful instrument for the diagnosis and analysis of body composition changes during the treatment of childhood obesity.
