Body fat percent consolidated

Derived variable from Anthro data. This is AD47_DEXA_body_fat_percent data if it is available (since this is better data) if not it is E_TANITA_BodyFatPcnt data.

Body fat percent device

Derived variable from Anthro data. To clarify whether BodyFatPercent_Cons data is DEXA data (AD47_DEXA_body_fat_percent) or Tanita data (E_TANITA_BodyFatPcnt). (Indicates the type of device that was used for reporting body fat percent for BodyFatPercent_Cons).

Body Fat percentage

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)
