- BACKGROUND: Obesity continues to increase in the world. It is strongly associated with morbidity, mortality, and decrease of health-related quality of life (HRQoL). Surgery is the most effective treatment for obesity, resulting in sustained weight loss and improvements of HRQoL. The aim of this study was to examine whether other factors, apart from weight loss, are associated with improvement in HRQoL scores between the preoperative visit and the 5-year follow-up.OBJECTIVES: To examine whether there are factors besides weight loss that affect the improvement of HRQoL from before to 5 years after gastric bypass surgery.SETTING: Large, nationwide, observational study with national quality and research registry.METHODS: Patients operated with a primary gastric bypass in Sweden between January 2008 and December 2012 were identified in the Scandinavian Obesity Surgery Register. Patients with HRQoL data available at both baseline and 5 years after surgery were included. Two HRQoL instruments, the RAND Short form-36 and the obesity-related problems scale, were used in the study.RESULTS: The study sample comprised 6998 patients (21% men). Differences in HRQoL change according to sex were minor. Younger patients showed greater improvements in physical health scales. In general linear regression model analyses, age and weight loss correlated significantly with improvement in HRQoL after 5 years. Patients treated medically for depression preoperatively (13%) experienced less improvement in HRQoL than patients without such treatment. Patients with postoperative complications (26%) had significantly less improvements in all aspects of HRQoL compared with those without any form of postoperative complication.CONCLUSION: The study confirmed the importance of weight loss for improvement in HRQoL after bariatric surgery. Preoperative medication for depression and suffering a complication during the 5-year follow-up period were associated with less improvement in HRQoL.

- It is evident that morbidly obese patients have a low health-related quality-of-life (HRQoL), and this low HRQoL has become a common reason for them to seek bariatric surgery. Several HRQoL studies demonstrate a dramatic postoperative improvement, but most of these have had a short follow-up period.An observational, cross-sectional study for HRQoL was conducted to study 486 patients (average age of 50.7 +/- 10.0 years, with 84 % of them being female) operated with gastric bypass (GBP) in the period 1993 to 2003 at the University Hospitals of A-rebro and Uppsala. Mean follow-up after gastric bypass was 11.5 +/- 2.7 years (range 7-17). Two HRQoL instruments were used, SF-36 and the Obesity-related Problems scale (OP). The study group was compared with two control groups, both matched for age and gender, one from the general population and one containing morbidly obese patients evaluated and awaiting bariatric surgery.The study group scored better in the SF-36 domains (all four physical domains and the vitality subscore) and OP scale compared to obese controls, but their HRQoL scores were lower than those of the general population. HRQoL was better among younger patients and in the following subgroups: men, patients with satisfactory weight loss, satisfied with the procedure, free from co-morbidities and gastrointestinal symptoms, employment, good oral status and those not hospitalised or regularly followed up for non-bariatric reasons.Long-term follow-up after GBP for morbid obesity showed better scores in most aspects of HRQoL compared to obese controls but did not achieve the levels of the general population. Patients with better medical outcome after gastric bypass operation had better HRQoL.

- Obesity is a risk factor for cardiovascular events. Weight loss might protect against cardiovascular events, but solid evidence is lacking.

- BACKGROUND: Obesity is associated with increased mortality. Weight loss improves cardiovascular risk factors, but no prospective interventional studies have reported whether weight loss decreases overall mortality. In fact, many observational studies suggest that weight reduction is associated with increased mortality. METHODS: The prospective, controlled Swedish Obese Subjects study involved 4047 obese subjects. Of these subjects, 2010 underwent bariatric surgery (surgery group) and 2037 received conventional treatment (matched control group). We report on overall mortality during an average of 10.9 years of follow-up. At the time of the analysis (November 1, 2005), vital status was known for all but three subjects (follow-up rate, 99.9%). RESULTS: The average weight change in control subjects was less than +/-2% during the period of up to 15 years during which weights were recorded. Maximum weight losses in the surgical subgroups were observed after 1 to 2 years: gastric bypass, 32%; vertical-banded gastroplasty, 25%; and banding, 20%. After 10 years, the weight losses from baseline were stabilized at 25%, 16%, and 14%, respectively. There were 129 deaths in the control group and 101 deaths in the surgery group. The unadjusted overall hazard ratio was 0.76 in the surgery group (P=0.04), as compared with the control group, and the hazard ratio adjusted for sex, age, and risk factors was 0.71 (P=0.01). The most common causes of death were myocardial infarction (control group, 25 subjects; surgery group, 13 subjects) and cancer (control group, 47; surgery group, 29). CONCLUSIONS: Bariatric surgery for severe obesity is associated with long-term weight loss and decreased overall mortality.
