… where are we?
Objective: The present review addresses the outcome of bulimia nervosa, effect variables, and prognostic factors. Method: A total of 79 study series covering 5,653 patients suffering from bulimia nervosa were analyzed with regard to recovery, improvement, chronicity, crossover to another eating disorder, mortality, and comorbid psychiatric disorders at outcome. Forty-nine studies dealt with prognosis only. Final analyses on prognostic factors were based on 4,639 patients. Results: Joint analyses of data were hampered by a lack of standardized outcome criteria. There were large variations in the outcome parameters across studies. Based on 27 studies with three outcome criteria (recovery, improvement, chronicity), close to 45% of the patients on average showed full recovery of bulimia nervosa, whereas 27% on average improved considerably and nearly 23% on average had a chronic protracted course. Crossover to another eating disorder at the follow-up evaluation in 23 studies amounted to a mean of 22.5%. The crude mortality rate was 0.32%, and other psychiatric disorders at outcome were very common. Among various variables of effect, duration of follow-up had the largest effect size. The data suggest a curvilinear course, with highest recovery rates between 4 and 9 years of follow-up evaluation and reverse peaks for both improvement and chronicity, including rates of crossover to another eating disorder, before 4 years and after 10 years of follow-up evaluation. For most prognostic factors, there was only conflicting evidence. Conclusions: One-quarter of a century of specific research in bulimia nervosa shows that the disorder still has an unsatisfactory outcome in many patients. More refined interventions may contribute to more favorable outcomes in the future.

… it’s not “just a phase”.
Potentially life threatening medical complications are ‘common’ in children affected by early onset eating disorders (EOEDs), a study reported in the Medical Journal of Australia has found.
The first prospective national study of EOEDs also revealed major limitations in current diagnostic criteria, possible missed diagnoses and a need for better education of health professionals. The study examined data from 101 cases of EOEDs in children aged five to 13 years, and found that 78% were hospitalised with an average length of stay of almost 25 days.
Study co-author and leading child psychologist Dr Sloane Madden, from Westmead Children’s Hospital, said the results show younger children with EOEDs are presenting with severe disease. “Only 37% of inpatients in the study met the current diagnostic criteria for anorexia nervosa, yet 61% had potentially life threatening complications of malnutrition and only 51 % met the weight criteria,” Dr Madden said. “This suggests the current criteria for diagnosing anorexia nervosa in young children are limited.”
An editorial on the study in the same edition of the MJA highlighted that about a quarter of cases in the study were boys. Editorial author, Foundation Chair of Mental Health at the University of Western Sydney’s School of Medicine, Professor Phillipa Hay, said “The relatively high proportion of younger boys with EOEDs contrasts with men accounting for about one in ten adult cases of anorexia nervosa and bulimia nervosa,” Professor Hay said. “More research is needed, but the work by Madden and colleagues supports the hypothesis that EOEDs may differ in important ways, including sex distribution and course, from eating disorders with onset in adolescence and adulthood. “It is imperative that research attention is now directed towards understanding why such young children are developing severe eating disorders and how effective identification and treatment can be targeted earlier.”
