title: A prospective assessment of psychosocial factors among bariatric versus non-bariatric surgery candidates.
abstract: BACKGROUND
  Psychological factors are considered potential contraindicators to bariatric surgery, but inconsistently predict surgical outcomes. We examined biomedical and psychosocial predictors of future bariatric candidacy in a population of veterans enrolling in a multidisciplinary weight management program.
  
  
  METHODS
  Ninety-five obese veterans meeting bariatric surgery eligibility criteria participating in a weight control intake class from 2007 to 2008 completed the MOVE!23 questionnaire to assess biomedical, psychiatric, social, and eating behavior factors. Twenty-five patients from this cohort completed or obtained approval for bariatric surgery during the next 2 years of follow-up.
  
  
  RESULTS
  Patients progressing to bariatric candidacy over follow-up differed from non-bariatric patients in multiple areas, including reporting significantly lower rates of depression (28% versus 48.7%, respectively; p = 0.04) and smoking (4% versus 16%; p = 0.05), better self-rated health (e.g., 28% versus 10.7% rating themselves as in excellent or very good health), and averaged 50% fewer cardiovascular risk factors (p = 0.01). Bariatric patients also rated themselves as significantly faster eaters (p = .03) and as having higher rates of obsessive compulsive disorder (OCD; 28% versus 7%; p = 0.04). Depression and OCD status predicted patients going on to bariatric candidacy independent of body mass index (BMI), biomedical status, and demographic factors.
  
  
  CONCLUSIONS
  Our results suggest that many of the commonly cited psychosocial contraindicators to bariatric surgery are already lower in patients considered for surgery relative to BMI equivalent treatment-seeking peers not approved for surgery. These differences may help explain inconsistent relationships between psychosocial factors and bariatric surgery outcomes.
