COSSIO-BOLANOS, Marco; COSSIO-BOLANOS, Wilbert; VARGAS VITORIA, Rodrigo  and  ARRUDA, Miguel. Concordance of percentage of body fat tissue determined with a specific equation compared to three generic equations in school age children of moderate altitude. Rev Med Hered [online]. 2013, vol.24, n.1, pp.33-39. ISSN 1018-130X.

Objective: Determine the concordance between the estimated percentages of body fat tissue using a specific equation with that of three generic equations in a school age population of moderate altitude. Methods: Descriptive-comparative study. A total of 321 girls and 338 boys aged 7-11 years from 4 Schools of urban Arequipa (altitude of 2320 masl) were selected by using probabilistic-stratified methods. Body weight, height, and skin fold calipers: bicipital, tricipital, subscapular and suprailiac. The percentage of body fat tissue was estimated using an specific equation A (Jaramillo and Rosell) and with three generic equations: B (Slaughter), C (Brook) and D (Boileau). Student´s t-test, Spearman´s correlation coefficient and analysis of variance using the Bland and Altman´s method were used to compare the results. Results: The concordance observed in girls between values obtained with equations A compared with B, C and D were 11.06, 3.71 and 2.00 respectively. Values for boys were 1.34, 1.34 and 1.58, respectively. Conclusions: The results suggest using Boileau´s equation for girls and boys and Salughter´s equation for girls.
