Abstract des Autors
The purpose of this study was to assess the accuracy of three recommended anthropometric equations for women and then develop an updated prediction equation using dual energy x-ray absorptiometry (DXA). The percentage of body fat (%BF) by anthropometry was significantly correlated (r=.896–.929; p<.01) with DXA, but each equation underestimated %BF (3.2–5.6 %BF; p<.01). The following DXA criterion (DC) equation was created: %BF=-6.40665+0.41946(S3SF)-0.00126(S3SF)2+0.1251(hip+0.06473(age); (S3SF=sum of triceps, suprailiac, thigh; hip=circumference in cm; age=years). The predicted residual sum of squares (PRESS) R2 was high (0.86), and the PRESS standard error of estimate (SEE) was low (2.5 %BF) for the sample of 150 women. The DC equation was further crosschecked on a separate sample of women (n=25) and again showed excellent agreement. The DC equation appears to be a more accurate estimation of %BF in women.
