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.
