title: Predictors of Health-Related Quality of Life After Bariatric Surgery.
abstract: BACKGROUND
  Bariatric surgery is typically associated with improvement in health-related quality of life (HRQoL). However, recent reports are conflicting, and the aim of this study was to determine factors that would be predictive for long-term outcomes after bariatric procedures.
  
  
  METHODS
  One thousand five hundred and seventy-three patients at one Midwestern academic medical center who underwent any type of bariatric surgery were sent the SF-36 survey. Three hundred and fifty completed surveys collected over a 3-month period were returned. Multivariate analysis was conducted.
  
  
  RESULTS
  The physical and mental component scores were significantly lower than the norm population mean. Age at time of surgery, pre-surgical body mass index (BMI) and duration since surgery were negatively related to HRQoL.
  
  
  CONCLUSIONS
  Improvements in HRQoL following bariatric surgery do not appear to be sustained over the long term. Older patients and those with high pre-surgical obesity do not appear to have the same benefits in HRQoL over time.
