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.
