Bioelectric-impedance analysis overestimates fat-free mass in obese people. No clear hypotheses have been presented or tested that explain this effect. This study tested the hypothesis that adipose tissue affects measurements of resistance by using data for whole body and body segment resistance and by using muscle, adipose tissue, and bone volumes from magnetic resonance imaging for 86 overwei...

OBJECTIVES This study was designed to investigate the properties of multiple bioelectric impedance signals recorded during congestive heart failure (CHF) by utilizing various electrode configurations of an implanted cardiac resynchronization therapy system. BACKGROUND The monitoring of CHF has relied mainly on right-side heart sensors. METHODS Fifteen normal dogs underwent implantation of c...

OBJECTIVE To investigate the accuracy of bioelectric impedance analysis and anthropometry to assess percentage body fat (BF %) against underwater weighing (UW). DESIGN AND METHODS A cross sectional study, 102 girls, aged 11-15, were recruited from two Junior High Schools in Jakarta. MEASUREMENTS Measurements of percent-age body fat (BF%) using underwater weighing (UW), bioelectrical impedan...

Metabolic syndrome is a cluster of disorders and great risk for cardiovascular diseases. We aimed to investigate association between severity of metabolic syndrome (MetS) and anthropometric measurements, and to evaluate correlation of MetS and its components with metabolic deterioration and inflammatory indexes. The cross-sectional study enrolled 1474 patients with obesity and overweight. The p...

Whole-body bioelectrical impedance analysis (BIA) was evaluated for its reliability and accuracy in estimating body composition in children. The hypothesis that the index, body height2 divided by resistance (RI), can accurately predict fat-free body mass (FFB) and percent fat (%FAT) in children was tested on 94 caucasian children 10-14 yr old. Criterion variables were FFB and %FAT estimated usi...

BACKGROUND Vesicoureteral reflux (VUR) is a common abnormality of the urinary tract in childhood. OBJECTIVES As urine enters the ureters and renal pelvis during voiding in vesicoureteral reflux (VUR), we hypothesized that change in body water composition before and after voiding may be less different in children with VUR. PATIENTS AND METHODS Patients were grouped as those with VUR (Group 1...

BACKGROUND: This field-based investigation examined the congruence between skinfolds and bioelectrical impedance in assessing body composition in children. METHODS: Subjects were 162 female and 160 male children 10-15 years of age. Skinfold measures obtained at the triceps and medial calf and a leg-to-leg bioelectrical impedance system were used to determine percent fat using child-specific equ...
