Anthropometric Predictors of Bio-Impedance Analysis (BIA) Phase Angle in Healthy Adults
Introduction: Phase Angle (PhA) is a ratio of whole body reactance and resistance obtained from Bioelectrical Impedance Analysis (BIA). It indicates cellular health and integrity and is considered as prognostic tool in medical disorders. In spite of prognostic potentials of PhA, it has limited u...

Introduction: Phase Angle (PhA) is a ratio of whole body
reactance and resistance obtained from Bioelectrical Impedance
Analysis (BIA). It indicates cellular health and integrity and is
considered as prognostic tool in medical disorders. In spite of
prognostic potentials of PhA, it has limited usefulness in clinical
practice and in population studies because of non-availability
of normal population reference limits for comparison. Moreover,
it is influenced by various factors like age, sex, race and body
composition (i.e. body fat, muscle mass, visceral fat, body cell
mass, total body water, etc).
Aim: The aim of this study was to evaluate predictors of phase
angle which will be useful in formulation of reference values for
Indian population.
Materials and Methods: BIA was performed by Tanita Body
Composition Analyser on healthy adults aged 17-24 years.
The inbuilt software measured the phase angle by the formula:
Phase angle (PhA) = Reactance (xc)/Resistance (R)* (180/π).
Phase angle values were compared across categories of age,
sex, weight, height, Body Mass Index (BMI), total fat, visceral
fat and muscle mass.
Results: Mean value of phase angle was found to be 5.65.
Phase angle was significantly (p< 0.001) higher in male than in
female. Phase angle was significantly predicted from height (p<
0.001), weight (p< 0.002), muscle mass (p< 0.002) and visceral
fat (p< 0.02) in multiple regression models.
Conclusion: Phase angle differs across anthropometric and
body composition categories. Thus height, weight and muscle
mass should also be taken into consideration while deriving
population specific reference limits of phase angle. |
