Girls and women with type 1 diabetes are at increased risk for developing eating disorders (EDs), and these disorders are associated with serious diabetes-related medical complications. This study describes the longitudinal course of disturbed eating behavior (DEB) and EDs in a cohort with type 1 diabetes. RESEARCH DESIGN AND METHODS A total of 126 girls with type 1 diabetes receiving care for diabetes at The Hospital for Sick Children in Toronto participated in a series of seven interview-based assessments of ED behavior and psychopathology over a 14-year period, begin-ning in late childhood. Survival analysis was used. RESULTS Mean age was 11.86 1.5 years at time 1 and 23.76 2.1 years at time 7. At time 7, 32.4 % (23/71)met the criteria for a current ED, and an additional 8.5 % (6/71) had a subthreshold ED. Mean age at ED onset (full syndrome or below the threshold) was 22.6 years (95 % CI 21.6–23.5), and the cumulative probability of onset was 60 % by age 25 years. The average time between onset of ED and subsequent E
