Official title
Identification of Biomarkers in Extracellular Vesicles Associated With Marrow Adiposity and Bone Deterioration Caused by Nutritional Deficiencies
Overview
The aim of this observational study is to identify biomarkers in extracellular vesicles associated with medullary adiposity occurring in patients with anorexia nervosa. The main question it aims to answer is: Can this medullary adiposity be associated with the bone deterioration observed in this population? Participants will be assessed for body composition and a blood sample will be taken by non-invasive techniques.
Primary outcome measures
- Biomarkers related to medullary adiposity [Time frame: 1 day]
Secondary outcome measures (2)
- Bone Mineral Density [Time frame: 1 day]
- Body Composition [Time frame: 1 day]
