Background. Our aim was to evaluate the changes of health-related Quality of Life (HR-QoL) after bariatric surgery. Patients and methods. 110 patients, who underwent laparoscopic bariatric surgery (N=34 gastric banding; N= 69 Roux-en-Y gastric bypass, N=7 sleeve gastrectomy), were evaluated before surgery and after an average of 36±13 months with SF-36 Health Survey. Results. Mean preoperative age and body mass index (BMI) were 43±12 years and 45±7 kg/m2 respectively. At follow-up, mean BMI was 33±6 kg/m2. A significant improvement was observed for all dimensions of SF-36, except for General and Mental Health dimension. Satisfaction was greater in patients with the higher reduction in weight. Only the PF (Physical Functioning) domain (F=6,349, p=0.01) resulted a significant predictor of the weight lost after surgery independently of age, sex and type of surgery. Conclusions. We confirm a beneficial effect of bariatric surgery on HR-QoL. Moreover, we found that PF domain of SF-36 is a significant predictor of weight loss.

Abstract
Background. Our aim was to evaluate the changes of health-related Quality of Life (HR-QoL) after bariatric surgery. Patients and methods. 110 patients, who underwent laparoscopic bariatric surgery (N=34 gastric banding; N= 69 Roux-en-Y gastric bypass, N=7 sleeve gastrectomy), were evaluated before surgery and after an average of 36±13 months with SF-36 Health Survey. Results. Mean preoperative age and body mass index (BMI) were 43±12 years and 45±7 kg/m2 respectively. At follow-up, mean BMI was 33±6 kg/m2. A significant improvement was observed for all dimensions of SF-36, except for General and Mental Health dimension. Satisfaction was greater in patients with the higher reduction in weight. Only the PF (Physical Functioning) domain (F=6,349, p=0.01) resulted a significant predictor of the weight lost after surgery independently of age, sex and type of surgery. Conclusions. We confirm a beneficial effect of bariatric surgery on HR-QoL. Moreover, we found that PF domain of SF-36 is a significant predictor of weight loss.
