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 (/spl alpha/), resistance (R), reactance (X/sub 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/spl plusmn/0.8/spl deg/ and 6.3/spl plusmn/0.6/spl deg/ with corresponding mean body capacitances of 818/spl plusmn/158 pF and 557/spl plusmn/101 pF for male and female, respectively. The results show that /spl alpha/ and BC mean values are higher in the male than the female. However, the female R (635/spl plusmn/71.5 /spl Omega/) and X/sub c/ (69.9/spl plusmn/8.4/spl Omega/) were higher than the male R (504/spl plusmn/63.4 /spl Omega/), and X/sub c/ (64.6/spl plusmn/6.8 /spl Omega/), respectively. These results show that the BETC values in Malaysian adults are in agreement with the normal healthy subjects at large.
