Please see the NIH reference site for a discussion of BIA Technology in the Estimation of Total Body Water (TBW), Extracellular Water (ECW) Fat-Free Mass, and Adiposity.
This is an area of active research and so specific methods of performing total body water (TBW) measurements using BIA may change. The following formula is sometimes used:
TBW = A * (H**2/R) + C
Where:
A = a proportionality constant specific for a given subject population
H = subject’s height
R = resistance obtained by single-frequency BIA (usually 50 kHz)
C = a constant
It may also be possible to obtain additional specificity in TBW measurements by performing BIA at multiple frequencies.
