Obese young people face more difficulties negotiating the tasks of adolescence than their healthy peers. Developmental issues and psychosocial aspects specific to this age group have to be part of regular health care strategies. We developed a global health assessment and a group approach based on health education principles focusing on knowledge, body sensations and emotional aspects in a developmentally appropriate way. This approach allows active participation of young people which has been shown to improve adherence to treatment and health outcomes.
