title: Male anorexia and bulimia nervosa: Disorder symptoms and impulsive behaviour during hospital treatment and one year follow-up period.
abstract: BACKGROUND
  The study aimed to evaluate treatment efficacy in male patients with anorexia (AN) and bulimia nervosa (BN) treated at the Eating Disorder Unit, University Psychiatric Clinic Ljubljana, Slovenia (EDU UPCL), using longitudinal assessments of eating disorder (ED) symptoms and selected impulsive behaviours highly correlated with these entities from hospital admission till twelve months after.
  
  
  METHODS
  35 male AN and 35 male BN patients were included. Participants were aged 17 or more and somatically stable with the BMI>12 kg/m(2). Patients with psychiatric comorbidity, mental disorder due to a general medical condition, or serious somatic or neurological disease were excluded. Intensity of ED symptoms and presence of selected impulsive behaviours were evaluated at hospital admission and discharge, and three, six and twelve months after, using an internal Eating Disorder Unit Questionnaire. For statistical analysis multivariate analysis of variance was used.
  
  
  RESULTS
  Throughout the research period the appropriate changes in BMI were observed in both patient groups. In both, AN and BN patient groups, the evaluation of longitudinal differences regarding the intensity of all ED symptoms and the presence of studied impulsive behaviours showed a significant decline at discharge and all subsequent assessments compared to the results obtained upon admission to the hospital. The re-hospitalization rates of patients with AN and BN in the first year after discharge from the hospital were 3.84% vs. 3.7% respectively.
  
  
  CONCLUSIONS
  In male patients with AN and BN treated at the EDU UPCL, ED symptoms, BMI, and studied impulsive behaviours show a substantial improvement during hospital treatment. These changes seem to be long lasting, still being effective through one-year post-hospitalization follow-up.
