Objective(s)Bioelectrical impedance is the measure of impedance of the body. Impedance consists of electric resistance and reactance. Phase angle (PA) is the tan value of the ratio of reactance versus electric resistance. PA depends on cell membrane integrity and on body cell mass. There exists a correlation between PA values and body cell mass.The objective of this study was to compare the PA values of normal individuals and their anthropometric measurements.Materials and MethodsAnthropometric measurements, Bioelectrical impedance analysis and PA measurements were done using Bodystat Quadscan ۴۰۰۰ machine on ۴۲ healthy subjects between the age group of ۱۸ to ۵۰ yrs at a private hospital, Bangalore, Karnataka, India for eight months. Kolmogrov-Smirnov and Pearson’s correlation tests were used for data analysis.ResultsThe PA values were ۷.۳۲۱.۱۷º in healthy subjects. PA values were significantly positively correlated with body mass index (BMI) (r= ۰.۰۱۱, P<۰.۰۰۱). The phase angle values for males and females were ۷.۴۳±۰.۹۸º and ۷.۰۵±۱.۱.۵۸º, respectively.ConclusionPA values positively correlated with BMI indicating the nutritional status of the study group. PA values were similar to the values to found in other studies.
