Résumé
Background. - To study the long-term prognosis of anorexia nervosa (AN), 484 adult AN patients were followed on a mean duration of 13 years. Results. - The mortality rate was 1.2%. Eight factors were linked to the lack of recovery at 2 years: low BMI at discharge, low energy and fat intakes, high drive for excessive exercising, high score for perfectionism, for interpersonal distrust and for anxiety, use of tube-feeding and adhesion to treatment (P < 0.02). Four factors explained the risk of the binge/purging form at 2 years: having had binge-eating disorder and overweight before AN, having had purging episodes within the first 2 years of AN; having had very high energy intakes through meals and being not treated by tube-feeding. During the 13-year follow-up, very few binge/purging patients turned out to have the restrictive form. Two main factors explained 67% of the variance of menses recovery: having a BMI > 18.5 kg/m(2); and having no physical hyperactivity. The recovery rate increased with the elapsing of relapse-free time (P = 0.02). After a 13.5-year follow-up, 292 out of the 484 patients were recovered (60.3%), 25.8% had a relatively good outcome, 6.4% a bad outcome and 6.4% a severe outcome. Very few factors were identified as predictors of a good outcome (binge-eating/purging subtype, personality disorder). (C) 2011 Elsevier Masson SAS. All rights reserved.
