Abstract

SILVA M, Héctor; COLLIPAL L., Erika; MARTINEZ, Cristian  and  BRUNEAU C, José. Evaluation of the Somatotipe Components and Body Mass Index in Scholarships of Foothills at the IX Región, Chile. Int. J. Morphol. [online]. 2005, vol.23, n.2, pp.195-199. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022005000200015.

World obesity has become a public health problem, Chilean adolescents do not escape this situation. Studies on body composition, nutritional state, and body mass index (BMI), are parameters recommended by the WHO for determining human beings' nutritional state. This study has been carried out to know the real of situation of adolescents living in the foothills of the Andes, in the IX Región in Chile. Six hundreds and sixty two subjects were evaluated, 358 men (54,1%) and 304 women (45,9%), between 11 and 15 years old, all students at urban municipal public schools, in the foothills of the Andes, in the IX Region of the Chilean Araucanía. In order to obtain the somatotype the anthropometric Health & Carter method was used, classifying BMI according to the WHO norms. The sample was mesoendomorphofic and indicated that the females were more endomorphic that males, being this difference statistically significant. The endomorphic and ectomorphic components presented no statically significant differences according to sex. The MBI showed values of 47% higher than the norm in males and of 33% over the norm in females. The sample presented a predominance of the mesomorphic component. The obesity rate was 2,7% and overweight was 10,7%. These results showed low prevalence of obesity contrasted with the national rate, the reasons could be rurality, poverty, food, and different life style in relation to city life

Keywords : Somatotype; Anthropometry; Body mass index.
