title: Axis I disorders in adjustable gastric band patients: the relationship between psychopathology and weight loss.
abstract: BACKGROUND
  Bariatric surgery candidates have higher rates of co-morbid psychological illnesses than those in the general population. The effect of weight loss on these illnesses is unclear.
  
  
  METHODS
  This prospective observational study explored psychiatric co-morbidities and weight loss outcomes in 204 gastric banding surgery candidates. Psychiatric co-morbidities were assessed prior to surgery and 2 years post-surgery. One hundred and fifty patients (74%) completed assessments at both time points.
  
  
  RESULTS
  At baseline, 39.7% of the patients met the criteria for a current axis I disorder as defined by the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV). Mood disorders were the most frequent (26.5%), followed by anxiety disorders (15.2%) and binge eating disorder (13.2%). Preoperative psychopathology predicted clinical psychopathology at 2 years. No preoperative or post-operative axis I disorder was significantly related to weight loss at 2 years. The frequency of current axis I disorders decreased significantly from 39.7% preoperatively to 20% 2 years post-surgery.
  
  
  CONCLUSIONS
  The point prevalence of psychopathology in this sample of Australian bariatric candidates is high. Psychopathology, preoperatively and at 2 years of follow-up, was not associated with weight loss at 2 years.
