Analysis of bioelectrical tissue conductivity in Malaysian adults

This paper presents the bioelectrical tissue conductivity (BETC) analysis of Malaysian adults using bioelectrical impedance. A total of 142 subjects (91(64.1%) female and 51(35.9%) male) with no past medical history were studied. The BETC was measured using phase angle (α), resistance (R), reactance (X_c) and body capacitance (BC). There is a significant difference (P<0.001) in the BETC mean values of the subjects. The mean phase angles measured were 7.4±0.8° and 6.3±0.6° with corresponding mean body capacitances of 818±158 pF and 557±101 pF for male and female, respectively. The results show that α and BC mean values are higher in the male than the female. However, the female R (635±71.5 Ω) and X_c (69.9±8.4Ω) were higher than the male R (504±63.4 Ω), and X_c (64.6±6.8 Ω), respectively. These results show that the BETC values in Malaysian adults are in agreement with the normal healthy subjects at large.
