Bioelectrical Impedance Analysis (BIA) and Phase Angle Introduction
T164, A0969, page 1442, journal of the American Society of Nephrology, September 1996, Volume 7, #9 Link not available Abstract: We performed a cross-sectional study of BIA (Bioelectrical impedance analysis, BIA 101-Q, RJL Systems, Clinton Township, MI) in 3009 HD (hemodialysis) patients with follow-up to 12 (median 8) months to evaluate the relation between impedance and survival. 296 deaths w...
متن کاملA bioelectrical impedance phase angle measuring system for assessment of nutritional status.
Bioelectrical impedance phase angle has been recommended as a tool to assess nutrition state, but there are no measuring devices have been specially designed for hospital residents. In this study, a system was established for the measurement of bioelectrical impedance phase angle. The electrical composition, calculation method and measuring method of this system are presented in this paper. Exp...
متن کاملBioelectrical impedance phase angle in clinical practice: implications for prognosis in advanced colorectal cancer.
BACKGROUND Phase angle, determined by bioelectrical impedance analysis (BIA), detects changes in tissue electrical properties and has been found to be a prognostic indicator in several chronic conditions-such as HIV, liver cirrhosis, chronic obstructive pulmonary disease, and lung cancer-and in patients receiving dialysis. OBJECTIVE This study was conducted to investigate the prognostic role ...
متن کاملBioelectrical impedance analysis: population reference values for phase angle by age and sex.
BACKGROUND Phase angle is an indicator based on reactance and resistance obtained from bioelectrical impedance analysis (BIA). Although its biological meaning is still not clear, phase angle appears to have an important prognostic role. OBJECTIVE The aim of this study was to estimate population averages and SDs of phase angle that can be used as reference values. DESIGN BIA and other method...
متن کاملDeterminants of bioelectrical phase angle in disease.
Phase angle (PhA), a parameter of bioelectrical impedance analysis, is a well-known predictor of morbidity and mortality in various diseases. The causes of decreased PhA are, however, not yet completely understood. We therefore investigated determinants of PhA in 777 hospitalised patients in a retrospective analysis. PhA was assessed by bioelectrical impedance analysis at 50 KHz. Subjective glo...
