BACKGROUND: The incidence of eating disorders appears stable overall, but may be increasing in younger age groups. Data on incidence, clinical features and outcome of early-onset eating disorders are sparse. AIMS: To identify new cases of early-onset eating disorders (8 months. A total of 50% were admitted to hospital, typically soon after diagnosis. Outcome data were available for 76% of individuals. At 1 year, 73% were reported improved, 6% worse and 10% unchanged (11% unknown). Most were still in treatment, and seven were hospital in-patients for most of the year. CONCLUSIONS: Childhood eating disorders represent a significant clinical burden to paediatric and mental health services. Efforts to improve early detection are needed. These data provide a baseline to monitor changing trends in incidence.
