Sarcopenic Obesity: Estimation of Prevalence and Identification of Clinical and Biological Determinants in a Population of Adult Obese Patients

Sarcopenic Obesity: Estimation of Prevalence and Identification of Clinical and Biological Determinants in a Population of Adult Obese Patients

This project aims first to determine the prevalence of sarcopenia in a population of obese people of extended age group (18-70 years). In a second step, the factors determining and / or predisposing to sarcopenic obesity will be identified as well as plasmatic and urinary biomarkers specific to this phenotype.

Collection of clinical and paraclinical data (biological and anthropometric) for evaluation of sarcopenic obesity in obese patients.

Biological collection to identify plasma, serum, genetic, urinary and faecal biomarkers associated with sarcopenic obesity

Inclusion Criteria:

• Patient followed in clinical nutrition benefiting from a metabolic assessment for optimization of clinical and paraclinical management
• Patient meeting the criteria of obesity defined by BMI> 30 kg / m²
• Major patient with free, informed and signed consent
• Patient covered by the social security scheme

Exclusion Criteria:

• Patient with cancer or severe chronic disease (renal failure, respiratory failure, liver failure)
