Measurement of body composition in chronic renal failure: comparison of skinfold anthropometry and bioelectrical impedance with dual energy X-ray absorptiometry

Article Abstract:

The measurement of percent total body fat (%TBF) and fat-free mass (FFM) by skinfold anthropometry (SFA) and bioelectrical impedance (BIA) differs from that obtained by dual energy X-ray absorptiometry (DEXA). The difference is higher in people suffering from chronic renal failure (CRF). The differences in the values of %TBF are higher than those of FFM for SFA and BIA in normal and CRF patients. In normal people the values of %TBF and FFM from BIA rather than SFA compare well with DEXA. Alterations in body composition in patients with CRF thus suggest caution in using either SFA or BIA, especially for measurement of %TBF.

Comparison of in-vivo body composition using two Lunar dual-energy X-ray absorptiometers

Article Abstract:

In vivo body composition analyses using two dual energy X-ray absorptiometers from the same manufacturer were compared. The Lunar DPX and Lunar DPX/L absorptiometers were compared with regards to quality assurance data, air-counts low, air-counts high, air-counts ratio, percent spillover, R-delrin, total body compartments, total body tissue, total body fat, total body lean, total body bone mineral content, and total body bone mineral density. Findings showed that it is important to conduct all body composition measurements on the same machine when performing longitudinal studies.

Skinfold thickness measurements are better predictors of body fat percentage than body mass index in male Spanish children and adolescents

Article Abstract:

Some 175 Spanish males aged seven to 16 were weighed underwater to obtain their body weight and height and skinfold thickness. These anthropometric measurements, in turn, will be used to develop equations for the assessment of the body density of the sample. The study found that log sigma 4 skinfolds as well as body mass index and triceps skinfold, were the best estimators of body density among the children and adolescents sampled.
