To describe the proportion of body fat mass, quantified from the measurement of 4 skinfold thickness, in a sample of male children of Zaragoza.
In 1995, we have studied 701 males aged 6.0 to 14.9 years, from 6 schools of the province of Zaragoza. We have measured: weight, height, and biceps, triceps, subscapular and suprailiac skinfold thicknesses. Body density has been calculated from the 4 skinfold measurements, with the formulas of Sarría et al. Fat mass (%), was calculated with the Weststrate and Deurenberg's formulas. In each age group, we present mean, standard deviation and 5, 25, 50, 75 and 95th percentiles.
We present mean, standard deviation and 5, 25, 50, 75 and 95th percentiles of body fat mass (%), in each age group. Body fat mass (%) progressively increased until 10.5 years and, after, progressively decrease at least until 14.5 years.
We present data of body fat mass (%), calculated from the measurement of 4 skinfold thicknesses, obtained from a reference population in the province of Zaragoza. These data are useful as more rationale criteria in the diagnosis of obesity in children and adolescents.
