What this trial studies

This clinical trial aims to compare the effectiveness of continued full-time hospitalization versus day patient treatment for children aged 8 to 13 years with early onset anorexia nervosa. The study will randomly assign participants to either remain in full-time hospitalization until reaching a minimum healthy weight or transition to day hospitalization after a short inpatient stay. The primary outcome will be the change in Body Mass Index (BMI) after one year, assessing the non-inferiority of day patient management. The trial will involve various therapeutic interventions, including medical evaluations, family sessions, and dietary follow-ups.

Who should consider this trial

Good fit: Ideal candidates for this study are children aged 8 to 13 years diagnosed with anorexia nervosa who require full-time hospitalization due to severe undernutrition.

Not a fit: Patients with other early onset eating disorders or significant psychiatric risks may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a less disruptive treatment option for children with anorexia nervosa, potentially improving their overall well-being and social integration.

How similar studies have performed: Previous studies have explored outpatient treatments for anorexia nervosa, but this specific comparison of inpatient versus day patient treatment in this age group is relatively novel.
