The objectives of the present study were to describe and compare the body composition variables determined by bioelectrical impedance (BIA) and the deuterium dilution method (DDM), to identify possible correlations and agreement between the two methods, and to construct a linear regression model including anthropometric measures. Obese adolescents were evaluated by anthropometric measures, and ...

UNLABELLED Limitations of current methods: Normalization of resting energy expenditure (REE) for body composition using the 2-compartment model fat mass (FM), and fat-free mass (FFM) has inherent limitations for the interpretation of REE and may lead to erroneous conclusions when comparing people with a wide range of adiposity as well as before and after substantial weight loss. EXPERIMENTAL ...

OBJECTIVE To determine the correlation between dual energy X-ray absorptiometry (DEXA) and skin fold thickness (SKF) equations for estimation of body fat (BF) composition in secondary school children and validation of prediction equations by Slaughter, Goran and Dezenberg. DESIGN Cross sectional analytical study. SETTING Joint Commission for International Accredited (JCIA) tertiary care hos...

BACKGROUND In newborns and children, body fat estimation equations are often used at different ages than the age used to develop the equations. Limited validation studies exist for newborn body fat estimation equations at birth or later in infancy. The study purpose was to validate 4 newborn fat mass (FM) estimation equations in comparison to FM measured by air displacement plethysmography (ADP...

Fractional Vegetation Cover (FVC) is an important parameter for soil erosion equation. The of typical county in red region South China was calculated by revision method (PRM) and fusion (FM).The results the two methods were compared from parts FVC level 24 half-months FVC. show that PRM concentrated high level, FM mainly medium-high level. time variation same, but majority value higher than FM....

INTRODUCTION there is hardly any reference in scientific literature regarding anthropometric characteristics, body composition and somatotype of hand Basque pelota players (pelotaris). OBJECTIVES the aim of this research was to analyze and compare the anthropometry features and body composition of professional pelotaris and under-23 (U23) pelotaris, to create an anthropometric profile of this...

OBJECTIVE To evaluate the applicability and validity of bioelectrical impedance analysis (BIA) compared with dual-energy X-ray absorptiometry (DXA) in a population of girls with restrictive anorexia nervosa (AN). METHODS A total of 30 girls (11-19 years old) with AN were enrolled. DXA and BIA (BIA software and the Deurenberg equations) were used to estimate the body composition. The correlati...

The application of Diierential Equation Interpolants (DEIs) to the visualization of the solutions to Partial Diierential Equations (PDEs) is investigated. In particular, we describe how a DEI can be used to generate a ne mesh approximation from a coarse mesh approximation; this ne mesh approximation can then be used by a standard contouring function to render an accurate contour plot of the sur...

This paper provides a robust statistical approach to nonstationary time series regression and inference. Fully modified extensions of traditional robust statistical procedures are developed that allow for endogeneities in the nonstation-ary regressors and serial dependence in the shocks that drive the regressors and the errors that appear in the equation being estimated. The suggested estima-to...
