Study of the Impact on the Evolution of the Disease in the Medium Term of the Implementation of a System of Extended Follow-up by Telephone Interview of Patients With an Eating Disorder Organized by the Nurses of the Eating Disorder Referral Center

The referral center for eating disorders provides for a systematic many years follow-up of patients under care with an annual assessment at the center. The investigators have recently shown the frequency of relapse in the first 7 years after diagnosis, but the literature remains poor on this epidemiology and on the risk factors for relapse. The investigators would therefore like to extend this follow-up for an additional 3 years after remission with an annual telephone nursing interview for all cured patients.
