The percentage of body FM was evaluated using a bioelectrical impedance analysis (BIA) system (Quadscan 4000; BodyStat Ltd ,Onchan, Isle of Man, UK).
Body composition is evaluated using a multifrequency bioelectrical impedance analysis (QuadScan4000, Bodystat; measure duration of about 30 s, after lying for 10 min) that provides body fat (%, kg), lean mass (%, kg), dry lean mass, basal metabolic rate, basal metabolic rate to weight ratio and body water (%, l; total, intracellular, extracellular).
We evaluated body fat composition by using bioelectrical impedance analysis at baseline and after 24 months.
This systematic error is concerning for studies using bioelectrical impedance to evaluate absolute fat mass and fat-free mass.
Fat free mass (kg) was estimated using bioelectrical impedance (BIA310, Biodynamics, US).
Both fat mass (g and %) and lean mass (g) of both legs was stimated using bioelectrical impedance (Tanita BC418-MA, Tanita Corp., Tokyo, Japan).
Resistance, reactance, impedance and PA at 50 kHz frequency were measured using bioelectrical impedance analysis (BIA 101S, Akern/RIL System, Florence, Italy).
We compared the fluid volume parameters in women undergoing gynaecological surgery for benign and malignant conditions before and after surgery using bioelectrical impedance vectors.
Percentage of body fat was measured using bioelectrical impedance (BIA-101, RJL systems, Detroit, MI, USA).
Subjects were weighed without shoes and hats, and their total body fat was determined using bioelectrical impedance analysis (BIA).
