“…Two models included SF and age, and one included BC, SF and height, all estimated in a group of 60 subjects and tested in another of 15 subjects. Rech et al 27 also tested the validity of anthropometric equations in agreement with DXA in an elderly population (n = 120 women and 60 men). The models chosen for analysis were based only on height, body mass, and BC.…”

Introduction: The increase in the prevalence of obesity entails the need for accurate low-cost methods to estimate body fat percentage (BF%). Objective: The aim of this study was to develop mathematical models to estimate the BF% of young women from southern Brazil using inexpensive equipment, based on body circumferences (BC), considering the shortage of specific studies of this population. Methods: Subjects were women (n=130) aged 18 to 35 years (26.06±4.41 years), from the city of Curitiba. Body mass and stature were measured and used to estimate body mass index (BMI), while BC measurements of the arm, forearm, waist (narrowest point and umbilicus), abdomen, hip, thigh and leg were taken for use in the mathematical models. Dual-Energy X-Ray Absorptiometry (DXA) equipment recorded the BF%. Pearson's correlation was used for anthropometric variables and age in association with BF%. The indicators with best correlations were used to estimate linear regression mathematical models for prediction of BF%. The results of the two models and of nine anthropometric equations were compared to those obtained with the DXA using Pearson's correlation coefficient and paired t-test. Results: Age was not significantly correlated with BF% (r=0.113 and p=0.200). The BCs with the highest correlations with BF% were abdomen, hip and waist -umbilicus (r=0.697, 0.682, 0.660, respectively, and p<0.001). Eight equations showed positive correlation with BF%, but only the results obtained with the models estimated in this study did not differ from those of DXA, with paired t-test. Mathematical models were developed with three (r=0.744, r²=0.554; t=0.16 and p=0.869) and six (r=0.768, r²=0.591; t=-0.04 and p=0.967) anthropometric variables. Conclusion: The use of mathematical models developed for estimating BF% based on body circumference and body mass is considered feasible.

Objetivo: O objetivo deste estudo foi desenvolver modelos matemáticos para calcular o GC% de mulheres jovens do sul do Brasil, usando equipamentos de baixo custo, com base em circunferências corporais (CC), considerando a escassez de estudos específicos dessa população. Métodos: Foram avaliadas mulheres (n = 130) com idade de 18 a 35 anos

“…Evidências apontam que a estimativa do %GC pode diferir dependendo da escolha da equação para estimar esta variável 26 . No presente estudo, observou-se que as equações testadas, em uma amostra de estudantes de Educação Física, apresentaram erros médios variando de -1,9 a 2,4 pontos percentuais em relação à medida adotada como critério (PH).…”

ResumoO objetivo deste estudo foi verifi car a validade das equações específi cas de GUEDES e GUEDES 7 e das generalizadas de PETROSKI 9 em universitários do sexo masculino. A amostra foi constituída de 104 universitários de Educação Física com idade média de 21,7 ± 2,7 anos, submetidos à pesagem hidrostática (PH) e à antropometria (dobras cutâneas e perímetros corporais). Não foram observadas diferenças estatisticamente signifi cativas entre as medidas de percentual de gordura pela PH e nove equações de PETROSKI 9 . Todos os resultados obtidos pelas equações de GUEDES e GUEDES 7 apresentaram diferenças signifi cativas quando comparados com os da PH. Entre as equações analisadas, oito desenvolvidas por PETROSKI 9 apresentaram validade concorrente na amostra estudada.

“…Currently, several methods and equations are used to estimate body composition 26,27,28 ; nevertheless, one of the main difficulties faced by the researchers who conduct studies on aging is to choose a method to evaluate body composition that is a simple, practical and reliable 29 . Anthropometry is still considered a practical and inexpensive method; its limitations, however, lie on the difficulty in choosing the best equation 30 and on the need of a skilled evaluator for the measurement of the SF.…”
