Abstract
The aim of this study was to investigate the validity of the Tanita TBF 300A leg-to-leg bioimpedance analyzer
for estimating fat-free mass (FFM) in Bangladeshi children aged 4-10 years and to develop novel
prediction equations for use in this population, using deuterium dilution as the reference method. Two
hundred Bangladeshi children were enrolled. The isotope dilution technique with deuterium oxide was
used for estimation of total body water (TBW). FFM estimated by Tanita was compared with results of deuterium
oxide dilution technique. Novel prediction equations were created for estimating FFM, using linear
regression models, fitting child's height and impedance as predictors. There was a significant difference in
FFM and percentage of body fat (BF%) between methods (p<0.01), Tanita underestimating TBW in boys
(p=0.001) and underestimating BF% in girls (p<0.001). A basic linear regression model with height and
impedance explained 83% of the variance in FFM estimated by deuterium oxide dilution technique. The
best-fit equation to predict FFM from linear regression modelling was achieved by adding weight, sex, and
age to the basic model, bringing the adjusted R2 to 89% (standard error=0.90, p<0.001). These data suggest
Tanita analyzer may be a valid field-assessment technique in Bangladeshi children when using populationspecific
prediction equations, such as the ones developed here.
