title: A comparison of clinical characteristics between adolescent males and females with eating disorders.
abstract: BACKGROUND
  Eating disorders (ED) are serious disorders that have a negative impact on both the psychological and the physiological well-being of the afflicted. Despite the fact that ED affect both genders, males are often underrepresented in research and when included the sample sizes are often too small for separate analyses. Consequently we have an unclear and sometimes contradictory picture of the clinical characteristics of males with ED. The aim of the present study was to improve our understanding of the clinical features of adolescent males with eating disorders.
  
  
  METHODS
  We compared age at presentation, weight at presentation, history of significantly different premorbid weight and psychiatric (Attention Deficit Hyperactivity Disorder (ADHD)) and somatic comorbidity (celiac disease and diabetes) of 58 males to 606 females seeking medical care for eating disorders at the Children's Hospital in Uppsala, Sweden during the years 1999-2012. As all boys were diagnosed with either AN or Other Specified Feeding or Eating Disorder (OSFED) atypical AN, the age and weight comparisons were limited to those girls fulfilling the diagnostic criteria for AN or OSFED atypical AN.
  
  
  RESULTS
  There was no significant difference in age at presentation. Differences in weight at presentation and premorbid weight history were mixed. A significantly higher percentage of males had a history of a BMI greater than two standard deviations above the mean for their corresponding age group. As well, there was a higher prevalence of ADHD among the males whereas celiac disease and diabetes only was found among the females.
  
  
  CONCLUSIONS
  A better understanding of the clinical characteristics of males with ED at presentation should improve our ability to identify males with ED and thereby aid in tailoring the best treatment alternatives.
