BIA

Abbreviation for bioelectrical impedance analysis.

bioelectrical impedance analysis

(bī″ō-ĭ-lĕk′trĭ-kĭl),

BIA

A method of body composition analysis useful in measuring the total body water and other components. BIA relies on the changes in electrical current as it travels through body fluids and tissues. The results obtained may vary with ambient temperature and humidity, the subject's hydration, and other variables.

impedance

(im-ped'ans) [L. impedire, to hinder]
Resistance met by alternating currents in passing through a conductor; consists of resistance, reactance, inductance, or capacitance. The resistance due to the inductive and condenser characteristics of a circuit is called reactance.

acoustic impedance

Resistance to the transmission of sound waves.

bioelectrical impedance

Abbreviation: BIA
Resistance to electrical current as it travels through body fluids and tissues. Its measurement is used in body composition analysis to determine total water, lean mass, and other body components. The results may vary with ambient temperature and humidity, the subject's hydration, and other variables. See: body composition; body fat; fluid, body; lean body mass

static acoustic impedance

Abbreviation: Za
The opposition to the passage of sound through the external auditory canal.

thoracic impedance

A measure of the electrical activity in the chest that varies with changes in body size and composition, fluid volume, ventilatory status, and other variables.

bioelectrical impedance

Abbreviation: BIA
Resistance to electrical current as it travels through body fluids and tissues. Its measurement is used in body composition analysis to determine total water, lean mass, and other body components. The results may vary with ambient temperature and humidity, the subject's hydration, and other variables. See: body composition; body fat; fluid, body; lean body mass
