Brief summary
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.
Detailed description
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Lin concordance coefficient | Day 0 | 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 |
