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.
