Konttinen H, Sjöholm K, Carlsson LMS, Peltonen M, Svensson PA. Fifteen-year changes in health-related quality of life after bariatric surgery and non-surgical obesity treatment. Int J Obes (Lond) 2024:10.1038/s41366-024-01572-w. [PMID: 38902388 DOI: 10.1038/s41366-024-01572-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Revised: 05/28/2024] [Accepted: 06/13/2024] [Indexed: 06/22/2024]
Abstract
BACKGROUND Evidence on the long-term (≥10 years) development of health-related quality of life (HRQoL) following bariatric surgery is still limited and mainly based on small-scale studies. This study aimed to investigate (1) 15-year changes in mental, physical, social, and obesity-related HRQoL after bariatric surgery and non-surgical obesity treatment; and (2) whether sociodemographic factors and pre-operative health status are associated with 15-year HRQoL changes in the surgery group. METHODS Participants were from the non-randomized, prospective, controlled Swedish Obese Subjects study. The surgery group (N = 2007, per-protocol) underwent gastric bypass, banding or vertical banded gastroplasty, and matched controls (N = 2040) received usual obesity care. Recruitment took place in 1987-2001 and measurements (including six HRQoL scales) were administered before treatment and after 0.5, 1, 2, 3, 4, 6, 8, 10 and 15 years. Multilevel mixed-effect regression models using all observations for estimation were conducted. RESULTS Surgical patients experienced greater 15-year improvements in perceived health and overall mood, and greater reductions in depression, obesity-related problems, and social interaction limitations than controls (all p < 0.001, adjusted for baseline differences). Effect size (ES) was classified as large only for obesity-related problems (ES = 0.82). At the 15-year follow-up, surgical patients reported better perceived health (p < 0.001) and less obesity-related problems (p = 0.020) than controls. In the surgery group, patients with baseline diabetes had smaller 15-year reductions in social interaction limitations (p < 0.001) and depression (p = 0.049) compared to those without baseline diabetes. Although surgical patients with a history of psychiatric disorder reported lower HRQoL than those without such history over the 15-year follow-up, there were no significant differences in the long-term improvements between the two groups (p = 0.211-0.902). CONCLUSIONS Over 15 years, surgical patients experienced more positive development of HRQoL compared to those receiving usual care. This difference was large for obesity-related problems, but otherwise the differences were small. Patients with pre-operative diabetes might be at increased risk for smaller long-term HRQoL improvements.

Clin Obes 2024:e12668. [PMID: 38641997 DOI: 10.1111/cob.12668] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/22/2024] [Revised: 04/02/2024] [Accepted: 04/10/2024] [Indexed: 04/22/2024]
Abstract
Bariatric surgery is an effective treatment for severe obesity, affording significant improvements in weight loss and health-related quality of life. However, bariatric surgeons' views on whether certain pre-operative factors predict improvements in post-operative health-related quality of life, and if so, which ones, are largely unknown. This cross-sectional survey study examined the views of 58 bariatric surgeons from Australia and New Zealand. A total of 18 factors were selected for exploration based on their mention in the literature. Participants rated the extent to which they thought these pre-operative factors would improve post-operative health-related quality of life. Responses showed that bariatric surgeons held diverse perspectives and revealed a lack of consensus regarding "predictive" factors. Generally, respondents agreed that better than average health literacy, higher socioeconomic status, good physical and psychological health, and positive social support were predictors of improved health-related quality of life following surgery. However, poor eating behaviours, smoking, and the use of alcohol or other substances were deemed negative predictors. Interestingly, aside from higher socioeconomic status, good psychological health, and positive social support, none of the aforementioned views aligned with existing literature. This study offers an initial insight into bariatric surgeons' views on the influence of different pre-operative factors on post-operative health-related quality of life. The array of views identified suggests that there may be an opportunity for medical education, but the findings warrant caution due to the sample size. Replication with a larger survey may be useful, especially as predicted health-related quality of life outcomes could guide decisions regarding surgical (non)progression.

Abstract
In 2007, the Scandinavian Obesity Surgery Registry (SOReg) was started by the profession to monitor the results of bariatric surgery and to provide a high-quality database for research. In the end of August 2023, SOReg contains 88,379 patients (body mass index [BMI] 41.7 kg/m2 , 41.2 years, 77.1% females, gastric bypass 76.8%). In this narrative review, we demonstrate that preoperative weight loss is of value and that the laparoscopic double omega-loop technique is highly suitable for gastric bypass. Closing the mesenteric openings is, however, important. Swedish bariatric surgery has low mortality, and our results are comparative to those of other countries. Significant long-term improvements are found in common obesity-related diseases such as diabetes, hypertension, and sleep apnea. Furthermore, the risk for cardiac failure and major adverse cardiovascular events is significantly reduced. Pregnancy-related outcomes are also improved. Gastric bypass results in significant improvements in quality of life and seems to be cost saving. We have revealed that low socioeconomic status is associated with reduced chance of undergoing bariatric surgery and inferior outcomes. Of note, we have performed several randomized clinical trials within the registry database. In conclusion, high-quality national registry databases, such as SOReg, are important for maintaining high-quality care and present a platform for extensive research.

Abstract
OBJECTIVE To study the effect of bariatric surgery on serum ghrelin in patients with morbid obesity. MATERIAL AND METHODS We experimentally analyzed serum ghrelin in 96 rats. Of these, 84 rats underwent sleeve gastrectomy, and 12 rats comprised the control group (no surgery). We measured body weight and serum ghrelin using ELISA method after 1, 3, 7, 14, 21 and 30 days after surgery. Serum ghrelin was studied before and after bariatric surgery in 23 patients with morbid obesity. RESULTS Baseline serum ghrelin was lower in larger rats and obese patients compared to normal body weight. We found no decrease in serum ghrelin after resection of fundal ghrelin-releasing part of the stomach. CONCLUSION Stomach volume changes after restrictive bariatric surgery (sleeve resection or gastroplication) are accompanied by mild increase in serum ghrelin. This increment is greater after more significant body weight loss after surgery. Similar researches will help to find new treatment strategies for pathological obesity.

Abstract
BACKGROUND The Metabolic and Bariatric Surgery Accreditation Quality Improvement Program (MBSAQIP) assesses safety after metabolic and bariatric surgery and the impact on weight and obesity-related diseases. However, changes in quality of life are likely what matters most to patients, and these are not currently assessed. The best way to measure health-related quality of life (HRQoL) is to use validated patient-reported outcomes measures (PROMs), which capture patients' perspectives of their quality of life both before and after surgery. OBJECTIVES Identify the outcomes most important to bariatric surgery patients and identify the most appropriate validated PROMs to implement in a national program for the MBSAQIP. SETTING Five hospitals from a single healthcare system in New England. METHODS A series of 18 focus groups and/or interviews conducted with patients, patients' family members, and bariatric health providers determined the outcomes most important to bariatric patients and which validated PROMs would accurately measure those outcomes. Immersion crystallization was used to analyze focus group data and identify appropriate PROMs. RESULTS Focus group participants ranked health as the most important outcome for metabolic and bariatric surgery. Self-confidence, mobility, and everyday activities were the next highest ranked HRQoL domains. The Patient-Reported Outcomes Measurement Information System 10-Item Global Health Survey was selected as the general health measure. The Obesity-Related Problems scale and the Obesity and Weight-Loss Quality of Life Instrument were the disease-specific measures selected for inclusion in the MBSAQIP PROMs program. CONCLUSION The addition of PROMs to the MBSAQIP provides a unique opportunity to monitor HRQoL at the national level, which can foster improved shared decision-making before surgery.

Abstract
BACKGROUND Negative psychological sequelae have been reported after bariatric surgery. It is unclear which factors affect psychological function in the first postoperative years. OBJECTIVE Evaluation of significant predictors of improved psychological function following bariatric surgery by analyzing data from the BODY-Q questionnaire. SETTING Multicenter prospective cohort in 3 centers located in The Netherlands and Denmark. METHODS The BODY-Q questionnaire was used to assess 6 domains of health-related quality of life. The domain of interest, psychological function, consists of 10 questions from which a converted score of 0 (low) to 100 (high) can be calculated. Linear mixed models were used to analyze which patient characteristics were most predictive of the psychological function score. Secondary outcomes of interest were cross-sectional scores of psychological function and the impact of weight loss, and the effect of major short-term complications on psychological function. RESULTS Data were analyzed from 836 patients who underwent bariatric surgery from 2015 to 2020. Patients with lower expectations concerning weight loss (<40% desired total weight loss), higher educational level, no history of psychiatric illness, and employment before bariatric surgery demonstrated the highest psychological function scores after bariatric surgery. At 1 and 2 years after bariatric surgery, more weight loss was associated with significantly higher psychological function scores. Experiencing a major short-term complication did not significantly impact psychological function. CONCLUSIONS Several relevant predictors of improved postoperative psychological function have been identified. This knowledge can be used to enhance patient education preoperatively and identify patients at risk for poor psychological functioning postoperatively.

Abstract
PURPOSE To investigate whether the quality-adjusted life years (QALYs) of the patients who underwent bariatric surgery could be predicted using their baseline information. MATERIALS AND METHODS All patients who received bariatric surgery in Sweden between January 1, 2011 and March 31, 2019 were obtained from the Scandinavian Obesity Surgery Registry (SOReg). Baseline information included patients' sociodemographic characteristics, details regarding the procedure, and postsurgical conditions. QALYs were assessed by the SF-6D at follow-up years 1 and 2. The general and regularized linear regression models were used to predict postoperative QALYs. RESULTS All regression models demonstrated satisfactory and comparable performance in predicting QALYs at follow-up year 1, with R2 and relative root mean squared error (RRMSE) values of about 0.57 and 9.6%, respectively. The performance of the general linear regression model increased with the number of variables; however, the improvement was ignorable when the number of variables was more than 30 and 50 for follow-up years 1 and 2, respectively. Although minor L1 and L2 regularization provided better prediction ability, the improvement was negligible when the number of variables was more than 20. All the models showed poorer performance for predicting QALYs at follow-up year 2. CONCLUSIONS Patient characteristics before bariatric surgery including health related quality of life, age, sex, BMI, postoperative complications within six weeks, and smoking status, may be adequate in predicting their postoperative QALYs after one year. Understanding these factors can help identify individuals who require more personalized and intensive support before, during, and after surgery.

Abstract
BACKGROUND Health-Related Quality of Life (HRQL) is a key outcome of success after bariatric surgery. Not all patients report improved HRQL scores postoperatively, which may be due to patient-level factors. It is unknown which factors influence HRQL after surgery. Our objective was to assess patient-level factors associated with HRQL after surgery. METHODS This international cross-sectional study included 730 patients who had bariatric surgery. Participants completed BODY-Q scales pertaining to HRQL and satisfaction with body, and demographic characteristics were obtained. The sample was divided into three groups based on time since surgery: 0 - 1 year, 1 - 3 years and more than 3 years. Uni- and multivariable linear regression analyses were conducted to identify variables associated with the BODY-Q scales per group. RESULTS The 0 - 1 year postoperative group included 377 patients (50.9%), the 1 - 3 years postoperative group 218 (29.4%) and the more than 3 years postoperative group 135 patients (18.2%). Lower current body-mass index (BMI), more weight loss (%TWL), being employed, having no comorbidities, higher age and shorter time since surgery were significantly associated with improved HRQL outcomes postoperatively. None of these factors influenced all BODY-Q scales. The effect of current BMI increased with longer time since surgery. CONCLUSION Factors including current BMI, %TWL, employment status, presence of comorbidities, age and time since surgery were associated with HRQL postoperatively. This information may be used to optimize patient-tailored care, improve patient education and underline the importance of long-term follow-up with special attention to weight regain to ensure lasting improvement in HRQL.

Abstract
INTRODUCTION To understand how individuals (self-)manage obesity, insight is needed into how patients perceive their condition and how this perception translates into health outcomes (e.g., health-related quality of life, HRQOL). Our objectives were (1) to examine illness perceptions in individuals with overweight and obesity, and (2) to investigate associations of these perceptions with physical and mental HRQOL. METHODS In a cross-sectional analysis of the Netherlands Epidemiology of Obesity Study (n = 6432; 52% women), illness perceptions were assessed using the Brief Illness Perception Questionnaire, and HRQOL was assessed using the 36-Item Short-Form Health Survey. Illness perceptions were calculated for different categories of overall, abdominal, and metabolically unhealthy obesity. We investigated associations of illness perceptions with HRQOL using BMI-stratified multivariable linear regression analyses. RESULTS Compared to individuals with normal weight, individuals with obesity believed to a higher extent that their condition had more serious consequences [Mean Difference (95%CI): 1.8 (1.6-2.0)], persisted for a longer time [3.4 (3.2-3.6)], manifested in more symptoms [3.8 (3.6-4.0)], caused more worry [4.2 (3.9-4.4)] and emotional distress [2.0 (1.8-2.2)], but was more manageable with medical treatment [3.1 (2.9-3.4)]. They perceived to a lesser extent that they had personal control [-2.2 (-2.4, -2.0)] and understanding [-0.3 (-0.5, -0.1)] regarding their condition. These negative perceptions were less pronounced in individuals with abdominal obesity. Behaviour/Lifestyle was attributed by 73% of participants to be the cause of their obesity. Stronger negative illness perceptions were associated with impaired HRQOL, particularly the physical component. CONCLUSION Individuals with obesity perceived their conditions as threatening, and this seemed somewhat stronger in individuals with overall obesity than those with abdominal obesity. Behaviour/Lifestyle is a crucial target intervention and empowering self-management behaviour to achieve a healthy body weight may deliver promising results. In addition, strategies that aim to change negative perceptions of obesity into more adaptive ones may improve HRQOL.

Is the RAND-36 an Adequate Patient-reported Outcome Measure to Assess Health-related Quality of Life in Patients Undergoing Bariatric Surgery? Obes Surg 2022; 32:48-54. [PMID: 34729711 PMCID: PMC8752557 DOI: 10.1007/s11695-021-05736-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2021] [Revised: 09/23/2021] [Accepted: 09/24/2021] [Indexed: 11/06/2022]
Abstract
PURPOSE The RAND-36 is the most frequently used patient-reported outcome measure (PROM) to evaluate health-related quality of life (HRQoL) in bariatric surgery. However, the RAND-36 has never been adequately validated in bariatric surgery. The purpose of this study was to validate the RAND-36 in Dutch patients undergoing bariatric surgery. MATERIAL AND METHODS To validate the RAND-36, the following measurement properties were assessed in bariatric surgery patients: validity (the degree to which the RAND-36 measures what it purports to measure (HRQoL)), reliability (the extent to which the scores of the RAND-36 are the same for repeated measurement for patients who have not changed in HRQoL), responsiveness (the ability of the RAND-36 to detect changes in HRQoL over time). RESULTS Two thousand one hundred thirty-seven patients were included. Validity was not adequate due to the irrelevance of some items and response options, the lack of items relevant to patients undergoing bariatric surgery, and the RAND-36 did not actually measure what it was intended to measure in this study (HRQoL in bariatric surgery patients). Reliability was insufficient for the majority of the scales (the scores of patients who had not changed in HRQoL were different when the RAND was completed a second time (intraclass correlation coefficient (ICC) values 0.10-0.69)). Responsiveness was insufficient. CONCLUSION The RAND-36 was not supported by sufficient validation evidence in patients undergoing bariatric surgery, which means that the RAND-36 does not adequately measure HRQoL in this patient population. Future research studies should use PROMs that are specifically designed for assessing HRQoL in patients undergoing bariatric surgery.

Vidarsson B, Löfling Skogar M, Sundbom M. Impact of a severe complication two years after laparoscopic Roux-en-Y gastric bypass: a cohort study from the Scandinavian Obesity Surgery Registry. Surg Obes Relat Dis 2021; 17:1874-1882. [PMID: 34373144 DOI: 10.1016/j.soard.2021.06.023] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2021] [Revised: 06/09/2021] [Accepted: 06/26/2021] [Indexed: 12/20/2022]
Abstract
BACKGROUND Although severe complications (SCs) after laparoscopic Roux-en-Y gastric bypass (LRYGB) are rare, they can be devastating for the affected patient. OBJECTIVE To access the impact of SCs (Clavien-Dindo ≥3b) 2 years after LRYGB by using a nationwide Swedish cohort of 48,201 primary cases between 2007 and June 2016. SETTING University hospital, Sweden. METHODS Patients with SC were matched 1:1 on age, sex, diabetic status, body mass index (BMI), and year of operation to patients without an SC. Weight loss, patient-scored quality of life (QoL), antidepressant use, proton pump inhibitors (PPI) and opioids, and in-hospital care were gathered from 3 national registers. RESULTS A total of 1411 (2.9%) patients suffered an SC and 16 (.03%) died. In total, 1403 patients with SC (mean age, 42 yr; female, 75%; with diabetes, 15.7%; mean BMI, 41.9 kg/m2) could be matched. Both groups had a total body weight loss of 32% at 2 years. A lower physical QoL was observed in SCs throughout the study period. Antidepressant, PPI and opioid use was higher among patients with SC, even 2 years after surgery. At this time point, a doubling of oral morphine equivalents (7.3 to 17.0 mg/d) was found in patients with SC compared with prior to surgery. The SC group required more in-hospital care after the initial 30 days (3.8 versus .9 d in the remaining part of the first year). CONCLUSION An SC resulted in higher antidepressant, PPI and opioid use as well as higher need for in-hospital care during the first 2 postoperative years. Affected patients should therefore receive special attention during follow up.

Gastrointestinal quality of life before and short- and long-term after Roux-en-Y gastric bypass for severe obesity. Surg Obes Relat Dis 2021; 17:1583-1590. [PMID: 34099420 DOI: 10.1016/j.soard.2021.05.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2021] [Revised: 04/26/2021] [Accepted: 05/11/2021] [Indexed: 11/20/2022]
Abstract
BACKGROUND Overall quality of life (QoL) is generally improved after bariatric surgery. Gastrointestinal (GI) symptoms including abdominal pain have been reported in up to >30% of patients after Roux-en-Y gastric bypass (RYGB), and may negatively influence QoL, especially GI-QoL. OBJECTIVES To evaluate the evolution of GI symptoms and GI-QoL short- and long-term after RYGB. SETTING Two public hospitals METHODS: Candidates for bariatric surgery (n = 128, BMI = 44.2 ± 7.4) or patients who had undergone RYGB 2-4 years (n = 161, BMI = 29.3 ± 15.9) and 5-10 years (n = 121, BMI = 31.3 ± 6.5) before were invited to complete a questionnaire combining 3 validated questionnaires (GIQLI, GSRS, and PCS) specifically designed to evaluate GI-QoL. Scores were compared between the preoperative, early, and late postoperative periods. RESULTS The GIQLI score improved from 88.1 before surgery to 118.6 (P < .0001) and 109.7 (P < .0001) in the early and late postoperative periods respectively. GSRS score improved from 15.6 to 10.1 (P = .0001) and 12.8 (P = .012), and PCS-score improved from 19 to 4.5 (P = .0001) and 8.3 (P = .0001), respectively. The GI subscore of the GIQLI improved from 57.4 to 62.1 (P = .007) in the early period but was not significantly different in the late period (59.3 versus 57.4, P = .3). The psychological impact of GI symptoms decreased at both postoperative time points. CONCLUSION GI-QoL is markedly improved after RYGB, and this improvement persists up to 10 years. GI symptoms decrease early after surgery and do not worsen in the longer term. Their psychological impact is markedly reduced.

Physical Activity Level, Sedentary Time, and Weight Regain After Bariatric Surgery in Patients Without Regular Medical Follow-up: a Cross-Sectional Study. Obes Surg 2021; 31:1705-1713. [PMID: 33409978 DOI: 10.1007/s11695-020-05184-x] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2020] [Revised: 12/19/2020] [Accepted: 12/21/2020] [Indexed: 10/22/2022]
Abstract
PURPOSE The impact of regular exercises or physical activity (PA) on weight of bariatric patients need to be elucidated. We investigated PA levels, sedentary time (ST), and weight regain on these patients who were without regular medical follow-up before recruitment. Moreover, we investigated correlation and concordance between self-reported and objective measures in moderate-to-vigorous PA (MVPA) and ST. MATERIALS AND METHODS We invited 132 patients previously subjected to a bariatric procedure to a medical appointment in our unit and proposed them to be volunteers. Ninety patients, aged 42 ± 8 years and BMI 32.9 ± 6.6 kg/m2, entered the study and were allocated into groups according to time since surgery < or ≥5 years (G5- or G5+, respectively). They were further assigned into low or high rates of weight regain (RWR; cutoff 20%). PA and ST were measured by International PA Questionnaire (IPAQ) and ActiGraph GT3X+ accelerometer. RESULTS In G5- group, PA and ST were similar between low and high RWR. In G5+ group, MVPA time, number of steps/day, percent of patients somewhat active, and 30-60 min/day of MVPA were statistically higher in those with low RWR. Of note, measures of MVPA < 30 min/day occurred more frequently in those with high RWR. MVPA and ST self-reported vs. objective measures were correlated (P < 0.001). Nevertheless, there was no concordance between these measures (P > 0.05). CONCLUSIONS Low level of PA and longer ST occurred more frequently in those with high RWR and longer time since surgery. Although well-correlated, any concordance between IPAQ and accelerometer measures was noted.

Using Bayesian Networks to Predict Long-Term Health-Related Quality of Life and Comorbidity after Bariatric Surgery: A Study Based on the Scandinavian Obesity Surgery Registry. J Clin Med 2020; 9:E1895. [PMID: 32560424 PMCID: PMC7356516 DOI: 10.3390/jcm9061895] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2020] [Revised: 06/15/2020] [Accepted: 06/15/2020] [Indexed: 11/16/2022] Open
Abstract
Previously published literature has identified a few predictors of health-related quality of life (HRQoL) after bariatric surgery. However, performance of the predictive models was not evaluated rigorously using real world data. To find better methods for predicting prognosis in patients after bariatric surgery, we examined performance of the Bayesian networks (BN) method in predicting long-term postoperative HRQoL and compared it with the convolution neural network (CNN) and multivariable logistic regression (MLR). The patients registered in the Scandinavian Obesity Surgery Registry (SOReg) were used for the current study. In total, 6542 patients registered in the SOReg between 2008 and 2012 with complete demographic and preoperative comorbidity information, and preoperative and postoperative 5-year HROoL scores and comorbidities were included in the study. HRQoL was measured using the RAND-SF-36 and the obesity-related problems scale. Thirty-five variables were used for analyses, including 19 predictors and 16 outcome variables. The Gaussian BN (GBN), CNN, and a traditional linear regression model were used for predicting 5-year HRQoL scores, and multinomial discrete BN (DBN) and MLR were used for 5-year comorbidities. Eighty percent of the patients were randomly selected as a training dataset and 20% as a validation dataset. The GBN presented a better performance than the CNN and the linear regression model; it had smaller mean squared errors (MSEs) than those from the CNN and the linear regression model. The MSE of the summary physical scale was only 0.0196 for GBN compared to the 0.0333 seen in the CNN. The DBN showed excellent predictive ability for 5-year type 2 diabetes and dyslipidemia (area under curve (AUC) = 0.942 and 0.917, respectively), good ability for 5-year hypertension and sleep apnea syndrome (AUC = 0.891 and 0.834, respectively), and fair ability for 5-year depression (AUC = 0.750). Bayesian networks provide useful tools for predicting long-term HRQoL and comorbidities in patients after bariatric surgery. The hybrid network that may involve variables from different probability distribution families deserves investigation in the future.
