Percent overall body fat from DEXA

Phase 2 data. Percent overall body fat from DEXA. Regenerated percentage body fat (overall fat) using a 3 compartment model (fat mass; fat free; mass bone mineral mass). Calculated as (100* fat mass / (total mass * 1000). Raw data from DEXA Lunar Prodigy processed with enhanced analysis. -9 = Missing data;

Body Fat Percent Cons Device

Phase 2 data. Derived variable from Anthro data. To clarify whether BodyFatPercent_Cons data is DEXA data (AD47_DEXA_body_fat_percent_P2) or Tanita data (E_TANITA_BodyFatPcnt_P2). (Indicates the type of device that was used for reporting body fat percent for BodyFatPercent_Cons_P2).

Body Fat Percent Cons

Phase 2 data. Derived variable from Anthro data. This is AD47_DEXA_body_fat_percent_P2 data if it is available (since this is better data) if not it is E_TANITA_BodyFatPcnt_P2 data.

Body Fat percentage

Phase 2 data. Data provided by Anthropometry team. Body Fat percent derived by in house prediction equations based on impedance and anthropometry values which were validated against DEXA values. The following equations were used 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 generate fat free mass (Ht2Im = height2/Impedance). Fat mass (weight - fat free mass) then percentage body fat (fat mass / (weight/100)) were derived. Further information on the validity can be provided by requesting the BIARegeneratedBodyFatPcnt document. -1 = unable to be determined; -7 = 0 values replaced; -9 = Missing data;
