This study describes the nutritional situation and body composition of a sample of municipal schools of the municipality of Padre las Casas. We evaluated 122 adolescents of both sexes, 65 men (53.2%) and 57 women (46.7%), between 9 and 12 years old. For body composition was used anthropometric method described by Dhebora Kerr, while evaluation and classification of nutritional status was conducted according to technical rules nutritional Chilean Health Ministry. The men had a body composition dominated muscle mass (MM) on the other components, with values of 38.79 +/- 3.65% at 9 years of age, 40.80 +/- 3.36% at 10 years age, 41.47 +/- 2.52% at 11 years of age, 43.35 +/- 1.59% at 12 years of age.
