Whole-body bioelectrical impedance analysis (BIA) is widely used by researchers and clinicians as a noninvasive and safe method to estimate body composition and body water volume in children and adults. Development of new approaches, such as segmental and multifrequency analyzers, should greatly expand the utility of this electrical technique. This article reviews the principles, underlying assumptions, clinical applications and future directions of the BIA method.
全身生物电阻抗分析（BIA）作为一种无创且安全的方法，被研究人员和临床医生广泛用于评估儿童和成人的身体成分及身体水分含量。诸如分段和多频分析仪等新方法的开发，应能极大地扩展这种电学技术的应用范围。本文综述了BIA方法的原理、基本假设、临床应用及未来发展方向。
