The objective was to develop a reference database for body composition of pediatric subjects in the province of Mendoza (Argentina). Data on I4 body composition variables (bone mineral density and composition; lean and soft mass; lean and body mass index, among others) were obtained from I98 subjects (96 women) aged 4 to 19 years. Subjects were classified into eight biennial groups; those in the pubertal transition stage were classified according to the Tanner stages. Measurements were obtained by dual X-ray densitometry on a Lunar Prodigy DF+I6206 instrument. For the statistical analysis, Prism 5.4 in MS Win 7 was used. The values of the variables analyzed increased with age. The values i n men follow a linear trend while in women it is sigmoid, except for the body mass index. Patients with the same age, but higher Tanner stage, showed higher values of body components. Women matured earlier It was concluded that the values of the variables analyzed increased with age and, to a lesser extent, with the Tanner stages. The changes are earlier and follow different time courses in women than in men.
