The aim was to analyse which of the anthropometric equations most commonly used to estimate the percentage of body fat is the most suitable for the school and adolescent population. The analysis of the corporal composition (CC) is a fundamental part in the valuation of the nutritional condition. Anthropometry is considered a useful tool to examine the changes in the corporal composition: It is not invasive and low cost and it is recommended by the WHO. Some equations of regression combining different variables and parameters anthropometrics to estimate the percentage of total fat mass (%TFM). To obtain precise results in not adult population turns out to be complex, given the inability to assume a corporal constant composition.
Conclussions:
To calculate body density, equations should be used that consider the sex and age of the subjects. The equations of Behnke and Lohman were found to be the most accurate methods for measuring body density in the population studied.
