Bioelectrical Impedance Analysis for Evaluation of Body Composition: A Review
Mahmood Aldobali, Kirti Pal
Abstract
Bioelectrical impedance (BIA) is a painless, non-invasive, and easily portable technique that may clarify how the human body is operational. Body composition (BC) assessment is commonly established as a clinical technique for evaluating and estimating disease status. BIA has been applied to assess the mass distribution and water compartments in the BC. BIA has several parameters: fat mass, fat-free mass, total body water, phase angle, and body mass index; these parameters show the body distributions. Thus, BIA could beneficially predict the patient’s status. However, more studies need to improve validity and reliability, according to these aspects. The purpose of this review was to briefly theoretical procedures of numerous compartments models of body composition.
