Comparison of Day Hospitalization Versus Full-Time Hospitalization in the Treatment of Severe Adolescent Obesity

Comparison of Day Hospitalization and Full-Time Hospitalization in the Treatment of Severe Adolescent Obesity (MAROSA)

This multicenter prospective quasi-experimental study aims to compare the effectiveness of day hospitalization versus full-time hospitalization for adolescents with severe obesity. The primary outcome is the change in BMI z-score measured six months after the end of treatment.

This study evaluates two healthcare delivery models for adolescents with severe obesity: day hospitalization and full-time hospitalization. It examines clinical, biological, psychological, and social outcomes, as well as patient satisfaction and predictors of response. The objective is to identify patient profiles that benefit most from each treatment modality to optimize care pathways
