Abstract:
Phase angle (PA), derived by bioelectrical impedance analysis, has been used to evaluate nutritional status.It has a unique advantage in diagnosing early malnutrition related to diseases by the detection of human body cell membrane integrity and fluid composition change, and being associated with bad disease prognosis in part of clinical research.Because of its non-invasive, convenient, accurate and affordable technique, it has a wide prospect of clinical application.However, lack of uniform PA reference value somehow limited its application.We summarize the latest clinical research and application situation of PA, and explore the characteristics and the influence factors of PA in different disease group, in order to provide theoretical basis for the Chinese PA reference range.
