Comparison of the predicting body fat equations during a maturation period in adolescent girls (12-16ys)

Validation of predicting fatness methods in the Iranian girls with respect to the maturity process could help to identify anthropometric risk factors. This study evaluate the accuracy of four body composition prediction equations in the teenager students in Hamadan city .Method: The anthropometry profile of 266 adolescent girls (12-16 ys) including ,weight (55.69±10.18 kg),body mass index (21.93±3.6 kg/m2) and percent body fat averages (29.65±4.41%) were measured using the bioelectrical impedance analysis (BIA) as a reference style and the selected skinfold prediction equations, ie, Durnin-Rahaman, Deurenberg , Westrate- Deurenberg, Slaugter. Results: Significant relationship was observed between BIA and four body composition prediction equations (p<0/05) with intervene the maturity level. However the most relationship was found among BIA method and Durnin-Rahaman logarithmic equation (R=0.82-0.92 ,p<001). Conclusion: It seems that physical education coaches and health-related organizations for athletic performance and Clinical assessments of body composition in young individuals probably can accurately utilized fat prediction, especially by applying the Diurnin- Rahaman skinfold equation.
