Estimation of human body composition by bioelectrical impedance measurements equation for estimating total body water in japanese subjects



Estimation of human body composition by bioelectrical impedance measurements equation for estimating total body water in japanese subjects



Japanese Journal of Physical Fitness & Sports Medicine 39(1): 53-59



A new method for estimation of total body water in human subjects by measurement of bioelectrical impedance is described. Determinations of impedance (Z) were made in 24 healthy women aged 35.9 .+-. 15.39 yr using an electrical impedance analyzer (T-1988 K, Toyo Physical Inc.) with a four-electrode arrangement that delivers a painless signal (500.mu.A at 50 kHz) into the body. The mean coefficient of variation for ten impedance measurements in 4 male subsamples was 0.8% (range, 0.2 .apprx. 1.2%). Total body water determined by deuterium-dilution was 26.1 .+-. 2.44 l. The estimation equation was developed by regression analysis of data from 24 women. Height2/resistive impedance was the most significant variable for prediction of deuterium-dilutoin space (TBW) and yielded r = 0.804 (p < 0.001) with a SE of estimate = 1.41 l. The regression equation generated was Total Body Water = 0.5294 (Ht2/Z) + 2.5139. These data indicate tht bioelectrical impedance measurement is a reliable and valid approach for the estimation of total body water in human subjects. This noninvasive method, which is safe, simple, rapid and convenient, should prove useful in a clinical setting, and also for epidemiological and exercise physiology studies.
