ABSTRACT To define whether reference values for bioimpedance analysis (BIA) can be predicted in healthy individuals, individual characteristics and BIA variables resistance index=height(2)/parallel resistance and reactance index=height(2)/parallel reactance) were evaluated in non-obese healthy individuals:863 men and 769 women with an age range 20-70 years and body mass index (BMI)19.0-29.9 kg/m(2).

ABSTRACT To define whether reference values for bioimpedance analysis (BIA) can be predicted in healthy individuals, individual characteristics and BIA variables resistance index=height(2)/parallel resistance and reactance index=height(2)/parallel reactance) were evaluated in non-obese healthy individuals:863 men and 769 women with an age range 20-70 years and body mass index (BMI)19.0-29.9 kg/m(2). The following predictive equations were obtained using multiple regression analysis:Resistance index (cm(2)/ohm)Males 21.06 + 0.087xage + 1.091xweight -1.801xBMI,Females 20.35 + 0.037xage + 0.878xweight - 1.343xBMIReactance index (cm(2)/ohm)Males 0.57 + 0.117xweight - 0.096xBMIFemales 1.42 + 0.078xweight - 0.075xBMI.
