Who Uses Bioelectrical Impedance?

Although BIA was primarily used to determine changes in dialysis patients [2], it is a method now used to determine body composition across a range of populations, including athletes [2, 3], obese individuals [4, 5] and the general population [3].

Is bioelectrical impedance commonly used?

Single-frequency BIA (SF-BIA) is the most commonly used, although this technique is limited in its ability to distinguish between intracellular and extracellular water and may be affected by hydration status or electrolyte imbalances.

What is bioelectrical impedance used for?

Bioelectrical impedance analysis (BIA) is a relatively simple, quick and non-invasive technique, to measure body composition. It measures body fat accurately in controlled clinical conditions but its performance in the field is inconsistent.
