This is a prospective multicentre study. Participating patients will be recruited from the Specialised Obesity Centres (CHU and SSR, as well as patient associations) to fill in a questionnaire and take part in an interview (a varied panel representative of the target population in terms of place of residence, socio-professional category, sex and age).
The medical and paramedical staff involved in the partner CSOs and the patients' resources (identified by the patients' associations) will also be asked to participate in a semi-directive interview.
