Popis:	Body composition and nutritional status were determined in a sample of 147 male adolescents. The sample was stratified by degree of maturation of external genitalia (GMGE) following Tanner procedures. Biochemical indicators were obtained for the study of nutritional status. Most subjects belonged to medium or low-medium socioeconomic level. Maximal growth rate both in Ht and Wt was observed betwaen GMGE 2 and 3 on the basis of a tissue containing 96% of LBM and 4% of fat. Between GMGE 1 and 2 growth rate is only 1/5 of that observed between GMGE 2 and 3. Tissue composition was 71% LBM and 29% fat. Betwaen GMGE 3 and 5 growth is also shower with 80% LBM and 29% fat. Deficit in the W/A ratio was observed in 47% of the sijects on the whole sample and in 54% of those subjects in GMGE=5. The W/H ratio was below 90% of the NCHS standard in 7% of the subjects. A W/H ratio ever 110% was found in 34% of subjects with GMGE=1. 9% of those with GMGE=5 had a W/H below 90%. Deficit in the H/A ratio was found in 32% of the subjects. Biochemical indicators of nutritional status were within normal limits, in all groups. Hemoglobin and Hematocrit levels increased significantly with each GMGE. Positive and significant correlation (p
