Clinical Evaluation Of An X-Ray Bone Densitometer:Use Of DXA Technology For Precise Assessment Of Human Body Composition

Diagnostic Medical Systems50 enrolled

Overview

The main objectives of this study are: * to assess the concordance of body composition measures between two bone densitometry devices: the STRATOS by Diagnostic Medical Systems (DMS) and the Hologic QDR 4500 A by Hologic inc. * to assess the concordance of body composition measures between two bone densitometry devices: the STRATOS by Diagnostic Medical Systems (DMS) and the Hologic HORIZON A by Hologic inc.

The secondary objectives of this study are: * the assessment of the consistency of body composition measurements at local level (arms, trunk, legs) between the Stratos and Hologic 4500 A, * the assessment of the consistency of body composition measurements at local level (arms, trunk, legs) between the Stratos and Hologic HORIZON A, * Monitoring the evolution of body composition in patients receiving at least two evaluations of DXA Hologic QDR 4500A on: patients treated for obesity or anorexia nervosa, sports people and other patient with prescription DXA and the assessment the consistency of body composition measurements in terms, * Monitoring the evolution of body composition in patients receiving at least two evaluations of DXA Hologic HORIZON A on: patients treated for obesity or anorexia nervosa, sports people and other patient with prescription DXA and the assessment the consistency of body composition measurements in terms.

Outcomes

Primary Outcomes

Lin concordance coefficient

In order to get a first idea of the adequacy of the two techniques measurements of the two bone densitometers, a calculation of intraclass correlation coefficients will be done. To supplement this data, a correlation study between the two techniques will be performed. For this we will use the Bland-Altman technique and a study of LIN concordance correlation coefficient
