E_BIARegeneratedBodyFatPcnt

Label

Body Fat percentage

Description

New in R7. Data provided by Anthropometry team. Body Fat % derived by in house prediction equations based on impedance and anthropometry values which were validated against DEXA values. We used the following equations in men: 16.34649+(Ht2Im*0.6493159)+( Weight*0.1334669)-(AgeAtTest *0.0801411) ; and in women: 13.09247+(Ht2Im*0.6587483)+( Weight*0.0914326)-(AgeAtTest *0.0660596) to firstly generate fat free mass then fat mass was derived as follows : weight - fat free mass and % derived: fat mass / (weight/100) ; further information on the validity can be found by requesting the BIARegeneratedBodyFatPcnt document.pdf. (Ht2Im = height2/Impedance)
