摘要
Predictive equations for body cell mass (BCM), fat free mass (FFM), and total body water (TBW), were derived, using single frequency bioimpedance analysis (BIA). Preliminary studies demonstrated more accurate predictions of BCM when using parallel transformed values of reactance than the values reported by the bioimpedance analyzer. Modeling equations derived after logarithmic transformation of height, reactance and impedance were more accurate predictors than equations using height2/resistance, and the use of gender-specific equations further improved accuracy. The addition of weight to the modeling equation also improved accuracy but was less important than the impedance measurements. These results indicate that body composition can be estimated accurately using simple, inexpensive, and easily applied techniques, and that the estimates are sufficiently precise for use in clinical investigation and clinical practice.
