Evaluation of a Day Hospital Program for Adolescents and Young Adults With Eating Disorders

This study aims to evaluate the clinical, psychological, and functional outcomes of adolescents with anorexia nervosa receiving multidisciplinary care in hospital settings. Participants are treated either in a day hospitalization program or in a full-time inpatient program, in accordance with the French national guidelines (Haute Autorité de Santé, HAS) for the management of anorexia nervosa. The study seeks to better understand the evolution of patients' health status over time, including nutritional, psychological, and social dimensions, and to identify factors associated with treatment response. Data will be collected as part of routine clinical care without modification of the standard therapeutic management. The results of this study may help improve clinical practices and optimize care pathways for adolescents with anorexia nervosa.
