“…This indicates that short-term reports (up to 1 year) of HRQL effects after bariatric surgery should be interpreted with caution. 7 Previously reported results from the SOS study have shown a positive relationship between weight reduction and HRQL improvements up to 4 years after intervention. 2,5,7 In the present study, we demonstrated that weight reduction after 6 and 10 years was also associated with improvements in HRQL, except for change in anxiety.…”

“…[2][3][4] Weight reduction in the severely obese is accompanied by improvements in HRQL and some studies indicate that a dose-response relationship exists between the magnitude of weight loss and HRQL benefits. [2][3][5][6][7][8] However, severe obesity is a refractory condition that is extremely difficult to master in the long run and conventional treatment, including various diet regimens, lifestyle modification programs and pharmaceutical agents, is relatively ineffective in the long-term perspective. 1 At present, surgical intervention is the only treatment alternative yielding more enduring weight loss and improvements in health status and HRQL.…”

Objective: To examine trends and effects of weight loss treatment on health-related quality of life (HRQL) in the severely obese over 10 years. Design: Swedish obese subjects (SOS) intervention study is a controlled, longitudinal trial of the health effects of weight loss in the severely obese. Subjects: A total of 655 of 851 surgically treated and 621 of 852 conventionally treated obese men (body mass index, BMIX34) and women (BMIX38) who completed 10 years of the study. Measurements: HRQL was assessed before treatment and after 0.5, 1, 2, 3, 4, 6, 8 and 10 years. Results: HRQL change during the 10-year observation period largely followed phases of weight loss, weight regain and weight stability. Improvements and deteriorations in HRQL were associated with the magnitude of weight loss or regain, except regarding anxiety. Peak improvements in the surgical group were observed during the first year of weight loss, whereas the weight regain phase (mainly between 1-and 6-year follow-up) was accompanied by a gradual decline in HRQL. The period from 6-to 10-year follow-up was characterized by relatively stable observations in both weight and HRQL. At 10 years, net gains were noted in all HRQL domains compared to baseline. Comparisons of treatment effects on HRQL in the surgical vs conventional group after 10 years showed significantly better outcome in the surgical group on current health perceptions, social interaction, psychosocial functioning and depression, whereas no significant differences were found for overall mood and anxiety. Long-term results of the study suggest that a maintained weight loss of about 10% is sufficient for positive long-term effects on HRQL, a limit that was reached in about two-thirds of the surgically treated patients who completed 10 years of the study. Conclusion: Long-lasting weight reduction in the severely obese has a general long-standing positive outcome on HRQL. Bariatric surgery is a favorable option for the treatment of severe obesity, resulting in long-term weight loss and HRQL improvements in a majority of patients. However, difficulties among some surgical patients to control and maintain weight loss over time should not be ignored. Future research should study if the long-term efficacy of bariatric surgery may be further enhanced by implementing lifestyle modification techniques in the postoperative management of patients.

Effect of a Culturally Adapted Behavioral Intervention for Latino Adults on Weight Loss Over 2 Years

Key Points Question Is a culturally adapted behavioral lifestyle intervention using technology more effective than usual care for weight loss among Latino adults in primary care? Findings In this randomized clinical trial of 191 Latino patients in primary care, a culturally adapted behavioral lifestyle intervention using technology, including web-based self-monitoring and a wearable activity monitor, was more effective for weight loss over 12 months but not 24 months. Meaning These findings suggest that the culturally adapted behavioral intervention using technology was not effective for long-term weight loss over 24 months, so research to optimize intervention effectiveness over 24 months is needed.

ImportanceResults from long-term follow-up after biliopancreatic diversion with duodenal switch (DS) are scarce.ObjectiveTo compare weight loss, health outcomes, and quality of life 10 years or more after Roux-en-Y-gastric bypass (RYGB) and DS surgery in patients with severe obesity—that is, a body mass index (BMI; calculated as weight in kilograms divided by height in meters squared) of 50 to 60.Design, Setting, and ParticipantsThis open-label randomized clinical trial was conducted at 2 academic bariatric centers in Sweden and Norway. Sixty patients with a BMI of 50 to 60 were included from March 1, 2006, to August 31, 2007. Data were analyzed from August 12, 2022, to January 25, 2023.InterventionsLaparoscopic RYGB or laparoscopic DS.Main Outcomes and MeasuresThe main outcome was change in BMI after 10 or more years. Secondary outcomes included anthropometric measures, lipid and glycemic profiles, bone mass density, adverse events, gastrointestinal tract symptoms, and health-related quality of life.ResultsForty-eight of the original 60 patients (80%) were assessed after a median of 12 (range, 9-13) years (mean [SD] age, 48.0 [6.0] years; 35 women [73%]). At follow-up, the mean BMI reductions were 11.0 (95% CI, 8.3-13.7) for RYGB and 20.3 (95% CI, 17.6-23.0) for DS, with a mean between-group difference of 9.3 (95% CI, 5.4-13.1; P &lt; .001). Total weight loss was 20.0% (95% CI, 15.3%-24.7%) for RYGB and 33.9% (95% CI, 27.8%-40.0%) for DS (P = .001). Mean serum lipid levels, except high-density lipoprotein cholesterol and hemoglobin A1c, improved more in the DS group during follow-up. Bone mass was reduced for both groups from 5 to 10 years, with lower bone mass after DS at 10 years. Quality-of-life scores (Obesity-Related Problem Scale and the 36-Item Short Form Health Survey) were comparable across groups at 10 years. The total number of adverse events was higher after DS (135 vs 97 for RYGB; P = .02). More patients in the DS group developed vitamin deficiencies (21 vs 11 for RYGB; P = .008) including 25-hydroxyvitamin D deficiency (19 for DS vs 9 for RYGB; P = .005). Four of 29 patients in the DS group (14%) developed severe protein-caloric malnutrition, of whom 3 (10%) underwent revisional surgery.Conclusions and RelevanceIn this randomized clinical trial, BMI reduction was greater after DS, but RYGB had a better risk profile over 10 years. Biliopancreatic diversion with DS may not be a better surgical strategy than RYGB for patients with a BMI of 50 to 60.Trial RegistrationClinicalTrials.gov Identifier: NCT00327912
