Alcohol Misuse post Metabolic and Bariatric Surgery: A Systematic Review of Longer-term Studies with Focus on new Onset Alcohol use Disorder and Differences Between Surgery Types

BACKGROUND

Evidence suggests an increased risk of alcohol problems post-surgery where no problematic alcohol use was present prior to surgery which may be different across types of surgery.

OBJECTIVE

To characterise the risk of new onset alcohol misuse post bariatric surgery, differences between surgeries and the impact over time.

METHODS

All published studies on new and relapsing alcohol use were reviewed. Data were classed as 'subjective' (clinical interview, self-report questionnaires) and 'objective' (hospital admissions, substance misuse programmes) and further categorised by follow up time - 'shorter-term' (one year), 'medium-term' (one year to two years) and 'long-term' (> two years).

RESULTS

Twenty-three of the forty-two studies included in the review reported new onset data. Nine studies reported on differences between surgery types. In those reporting objective measures, all of which were long term, RYGB carried a higher risk than SG, followed by LAGB. All but one study using subjective measures reported a small but significant number of new onset concerning alcohol use, and comparisons between surgery types had more varied results than the objective measures. Studies of substance abuse programmes found high rates of new onset cases (17-60%).

CONCLUSION

This systematic review provides support for the consensus guidance suggesting patients should be informed of a small but significant risk of new onset alcohol use following bariatric surgery, with the strongest evidence in the medium- to long-term and in those who have had RYGB followed by SG.

Assessment of guidelines for bariatric and metabolic surgery: a systematic review and evaluation using appraisal of guidelines for research and evaluation II (AGREE II)

BACKGROUND

In recent years, multiple guidelines on bariatric and metabolic surgery were published, however, their quality remains unknown, leaving providers with uncertainty when using them to make perioperative decisions. This study aims to evaluate the quality of existing guidelines for perioperative bariatric surgery care.

METHODS

A comprehensive search of MEDLINE and EMBASE were conducted from January 2010 to October 2022 for bariatric clinical practice guidelines. Guideline evaluation was carried out using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) framework.

RESULTS

The initial search yielded 1483 citations, of which, 26 were included in final analysis. The overall median domain scores for guidelines were: (1) scope and purpose: 87.5% (IQR: 57-94%), (2) stakeholder involvement: 49% (IQR: 40-64%), (3) rigor of development: 42.5% (IQR: 22-68%), (4) clarity of presentation: 85% (IQR: 81-90%), (5) applicability: 6% (IQR: 3-16%), (6) editorial independence: 50% (IQR: 48-67%), (7) overall impressions: 48% (IQR: 33-67%). Only six guidelines achieved an overall score >70%.

CONCLUSIONS

Bariatric surgery guidelines effectively outlined their aim and presented recommendations. However, many did not adequately seek patient input, state search criteria, use evidence rating tools, and consider resource implications. Future guidelines should reference the AGREE II framework in study design.

Cross-cultural validation and Spanish translation of the Boston Interview to evaluate severely obese patients seeking metabolic/bariatric surgery

INTRODUCTION

obesity is a global health problem. Metabolic/Bariatric surgery (MBS) has proven to be one of the most effective methods for treating the most severe forms. However, a thorough evaluation and preparation of people seeking MBS is necessary. In Spain, there are no standardized interviews to carry out the psychosocial assessment of people seeking MBS. The Boston Interview for MBS (BIBS) is a recognized and flexible tool to evaluate the psychosocial factors.

OBJECTIVE

to present the process of translation into Spanish and cross-cultural adaptation of the BIBS.

MATERIALS AND METHODS

the reverse translation procedure was followed. To validate the translation, a multidisciplinary group of experts was formed. They were asked to rate the clarity of wording and cultural adaptation of the translation items. In addition, the translated interview was used to evaluate 173 patients seeking MBS who rated their satisfaction with the interview experience.

RESULTS

the evaluation of the translation by a group of experts was favorable (global mode and median were 3-excellent, IQR of 1). The overall percentage agreement of the adequacy of "cultural adaptation" of the text was 85.8 % (95 % CI, 0.784, 0.932) and of the "clarity of wording" was 84.7 % (95 % CI, 0.7644; 0.9286). Furthermore, it was well accepted by the majority of the patients interviewed (p(50) 10 out of 10).

CONCLUSIONS

the Spanish translation of the BIBS is available for the assessment of Spanish-speaking people seeking MBS. It was rated as having good fidelity to the original English version, and was deemed highly satisfactory by patients.

'Surgery is my only hope': A qualitative study exploring perceptions of living with obesity and the prospect of having bariatric surgery

The health benefits of bariatric surgery are well documented; however, the occurrence of weight-regain after surgery, along with the development of mental health difficulties poses a question of how contemporary psychology could assist to prepare people living with obesity prior to undergoing bariatric surgery. This research explored individuals' (in the immediate pre-operative and post-operative population) attitudes, beliefs and experiences towards obesity and their journey to bariatric surgery. Seventeen adult participants (males n = 4; age range: 26-64 years) were recruited and participated in a semi-structured interview. Twelve individuals participated prior to undergoing bariatric surgery. Five individuals participated in the early post-operative period (<3 months post-surgery). People living with obesity displayed high optimism for positive outcomes, with participants hoping that bariatric surgery would be different to previous attempts at weight regulation, with there being a clear shift in the locus of control for weight management from self to healthcare professionals. Whilst this is adaptive, there was the presence of seemingly unrealistic optimism, with many pre-surgery participants not relaying the realistic possibility of post-surgery weight-regain. Despite the optimism individuals feel about bariatric surgery, participants felt that the psychological factors influencing eating behaviours are not being addressed by healthcare. These findings suggest that mindfulness, mindful eating, and self-compassion approaches should be incorporated into clinical practice to support weight regulation and adaption to physiological changes after bariatric surgery.

The Prevalence and Consequence of Depression After Bariatric Surgery Among Adults in Saudi Arabia

BACKGROUND

Bariatric surgery is a commonly performed group of procedures for individuals with severe obesity, and its impact on mental health, particularly depression, has gained significant attention. In Saudi Arabia, the prevalence and consequences of depression following bariatric surgery among adults is an area of growing concern. The study aimed to assess the prevalence of depression after bariatric surgery and estimate the consequences of depression after bariatric surgery.

METHODS

A cross-sectional study was conducted among adults in Saudi Arabia who had undergone bariatric surgery. The participants were recruited from different bariatric surgery centers across the country. The data was collected using a self-administered questionnaire that had three main sections, including demographic information, clinical characteristics, and the Patient Health Questionnaire-9 (PHQ-9) to assess depression.

RESULTS

The results of the study showed that among adults in Saudi Arabia who had undergone bariatric surgery, the prevalence of depression was high. Of the participants, 23.5% were found to have depression after bariatric surgery. This high prevalence suggests that depression is a significant consequence of bariatric surgery.

CONCLUSION

A high number of adults in Saudi Arabia experience depression after bariatric surgery. This shows a need for mental health checks and support before and after the surgery. With mental healthcare as a regular part of bariatric programs, patients would have a better chance of success and overall well-being. More research is needed to understand why depression happens after surgery and how to prevent it.

Mind the gap! Factors that predict progression to bariatric surgery indicate that more psychological treatment may be required

In the UK, the number of adults living with obesity is increasing. Bariatric surgery is an available treatment for those living with a BMI (kg/m2 ) ≥40 and above, or ≥35 with obesity-related comorbidities. Guidelines highlight the importance of providing psychological support pre- and post-surgery owing to the complex psychopathology present in those living with obesity. There are a lack of studies examining which patients proceed to surgery and the factors that predict progression. Routine patient data were collected within one NHS regional service in the UK, comprising 733 patients between 3 August 2018 and 26 July 2019, aged between 17 and 76 years (M = 43.20, SD = 12.32). The only exclusion criteria were patients still awaiting a final decision for surgical outcome at the point of analysis (N = 29), which resulted in 704 patients included in analysis. Binary Logistic Regression revealed those who were more likely to progress to surgery had a lower-level use of maladaptive external substances; lower level of self-harm and/or suicidality, were older in age; had a lower BMI; and had less comorbidities than those who did not progress. Findings support existing literature in that bariatric patients often present with physical and mental health complexity. Two thirds of patients in this study did not progress to surgery. Service commissioning decisions meant that these patients did not have access to psychology treatment. Consequently, in cases where bariatric surgery is considered, a final treatment option and otherwise clinically appropriate, lack of access to specialist services may result in unmet patient need owing particularly to a lack of psychological treatment provision.

The patient-practitioner interaction in post bariatric surgery consultations: an interpersonal process recall study

PURPOSE

The patient-practitioner relationship is fundamental to rehabilitation practice and patients' health and wellbeing. Dissonance between patients who have had bariatric surgery and health care practitioners about what supportive care and good outcomes are can undermine care. To address the mechanisms of this process, we conducted an Interpersonal Process Recall study.

MATERIALS AND METHODS

We interviewed patients (11), video recorded consultations (10), conducted video-assisted individual interviews with patients (10) and practitioners (11) and a dyadic data analysis.

RESULTS

We identified relational states and shifts in the clinical encounter 2-3 years post-surgery, described in themes: a) Playing by the Book - Making it Easier for Each Other, b) Down the Blind Alley - Giving up on Each Other, and c) Opposite Poles - Towards and Away from Each Other.

CONCLUSIONS

The post-surgery consultations facilitated responsibility for health and self-care but did not invite dialogues about the psychosocial burdens of living with obesity and undergoing bariatric surgery. Patients and practitioners tried to avoid creating conflict, which in turn seemed to foster distance, rather than human connection. This limits the encounter's benefit to both parties, leaving them frustrated and less willing to either meet again or take any gains into their future lives.IMPLICATIONS FOR REHABILITATIONIllness evokes feelings of stress and uncertainty and is experienced very differently from the perspective of patients and health care practitioners (HCPs), who encounter each other in a field fraught with tension.Bodily changes and difficult emotions related to food and eating are to be expected when undergoing bariatric surgery, and to explicitly "notice, name and validate" emotions can promote the patient's capacity to sustain self-care, lifestyle change, weight loss and health gains.Making interpersonal connection and interaction between patient and HCP the centre of bariatric aftercare can enhance engagement in and outcomes of the post-surgery clinical encounter.

What is the role of psychology in bariatric surgery? A survey of the differing views of psychologists, the multidisciplinary team, and patients in the UK

Although psychologists are a key member of the bariatric multidisciplinary team (MDT), there is a lack of clarity about the specific remit of their role. This exploratory study was conducted to identify differences, priorities and clarify how the role of psychology is perceived in the United Kingdom. We conducted surveys of three major stakeholder groups (psychologists, patients, and the bariatric multidisciplinary team) which focused on their perception of psychology in bariatric surgery. The results showed that in UK bariatric services, psychologists are spending the majority of their clinical time providing pre-operative assessments. Differences emerged between psychologists and MDT in how they viewed the purpose of these assessments, with the MDT viewing them as identifying contraindications to surgery whereas psychologists viewed them as identifying readiness for surgery. A total of 51% of patients reported they had not been able to access psychology services when needed and viewed provision of post-operative psychological support to be a key priority. Key themes and tensions emerged around (a) high demand for services yet limited psychology resource, (b) the purpose of the pre-operative assessment and (c) the provision of pre-operative versus post-operative support. These themes combine and interact in a way that currently makes it extremely challenging to provide coherent psychology services. There is clearly a need for education, consensus and adequate resourcing of the psychology role within bariatric surgery services in the United Kingdom.

The forgotten patient: A psychological perspective on the implementation of bariatric surgery guidelines

There is strong evidence demonstrating the impact of bariatric surgery on weight-loss and comorbidity improvement. In the UK, there is specific guidance to facilitate the assessment of a person's suitability for bariatric surgery. This paper highlights the clinical reality of routinely implementing this guidance, supported by literature and the perspectives of practicing psychologists. The consequences of the implementation of clinical guidelines within the context of the typical biopsychosocial profile of those referred for bariatric surgery are discussed. The ramifications of a screening approach rather than a clinical formulation-based approach to assessment, impact of a possible unconscious bias in commissioning and an overemphasis on a biomedical model approach to treatment are also presented. These contextual factors are argued to contribute to a population of "forgotten patients" that is, patients who have been assessed as not suitable for bariatric surgery, and thus "stuck" in their journey toward better health. For these individuals the only option left are energy balance only approaches, which are the very same approaches to weight-loss and comorbidity improvement that have been attempted, often for many years. Not only have these approaches not resulted in weight-loss and health improvement, they also fail to address the underlying psychological causes of obesity. Consequently, this lack of support means that patients continue to suffer from poor quality of life, with no clear pathway to improved health and wellbeing. This paper illuminates the clear gaps in weight management service provision, the implementation of guidelines in practice, and offers practical suggestions to reduce the unintended consequences of clinical guidelines for bariatric surgery.

Patients' Perspectives on Dietary Patterns and Eating Behaviors During Weight Regain After Gastric Bypass Surgery

PURPOSE

Food quality, energy intake, and various eating-related problems have been highlighted as some of the components influencing weight after bariatric surgery. This study aimed to increase our knowledge of patients' perspectives on dietary patterns and eating behaviors during weight regain after bariatric surgery.

MATERIALS AND METHODS

We recruited 4 men and 12 women with obesity and the experience of weight regain after bariatric surgery at an obesity clinic in Stockholm, Sweden. Data were collected during 2018-2019. We conducted a qualitative study, carried out individual semi-structured interviews, and analyzed the recorded and transcribed interview data with thematic analysis.

RESULTS

Participants had regained 12 to 71% from their lowest weight after gastric bypass surgery performed 3 to 15 years before. They perceived their dietary challenges as overwhelming and had not expected weight management, meal patterns, increasing portion sizes, and appealing energy-dense foods to be problematic after surgery. In addition, difficulties with disordered eating patterns, emotional eating, and increased alcohol intake further contributed to the weight management hurdles. Insufficient nutritional knowledge and lack of support limited participants' ability to avoid weight regain, leading to restrictive eating and dieting without sustained weight loss.

CONCLUSION

Eating behavior and dietary factors such as lack of nutritional knowledge, emotional eating, or disorganized meal patterns contribute to difficulties with weight management after gastric bypass surgery. Improved counseling may help patients prepare for possible weight regain and remaining challenges with food and eating. The results highlight the importance of regular medical nutrition therapy after gastric bypass surgery.

Screening Risks of Alcohol Abuse, Depressive Symptoms, and Decreased Health-Related Quality of Life in Post-Bariatric Patients and Their Relations to Weight Regain

PURPOSE

Not all patients who underwent bariatric surgery keep their regular medical follow-up. We screened alcohol use, depressive symptoms, and health-related quality of life (HRQoL) in post-bariatric patients who have lost medical follow-up at their first appointment in our healthcare unit. These screened disorders were compared between low vs. high ratios of weight regain (RWR) and correlated with surgical outcomes.

MATERIAL AND METHODS

Ninety-four post-bariatric patients without medical follow-up (87.2% female, aged 42 ± 9 years, BMI = 32.9 ± 6.5kg/m²) were included. They underwent Roux-en-Y gastric bypass (n = 80) or sleeve gastrectomy (n = 14). They were divided into high RWR (≥ 20%) and low RWR (< 20%) groups. We used Alcohol Use Disorders Inventory Test, Beck Depression Inventory, and 36-Item Short-Form Health Survey.

RESULTS

Neck and waist circumferences, diastolic blood pressure, and time since surgery were higher in the high than low RWR group (P≤ 0.05). No differences between groups for alcohol use and depressive symptoms were detected (P≥ 0.07), but those who regained more weight exhibited poorer health scores in physical functioning, physical role limitations, bodily pain, and vitality (P≤ 0.05). In the low RWR group, the RWR was inversely correlated to physical/social functioning and vitality. Positive associations were present between RWR vs. depressive symptoms, while negative ones were noted to physical functioning and general health perception in the high RWR group.

CONCLUSIONS

HRQoL has deteriorated in those post-bariatric patients without medical follow-up who regained more weight, possibly indicating the need for regular long-term health care.

Bariatric Surgery and Psychological Health: A Randomised Clinical Trial in Patients with Obesity and Type 2 Diabetes

PURPOSE

This study investigated the impact of either Roux-en-Y gastric bypass with silastic ring (SR-RYGB) or sleeve gastrectomy (SG) types of bariatric surgery on psychological health and explored the role of pre-existing depressive symptoms on weight loss.

MATERIALS AND METHODS

A total of 114 participants with obesity and type 2 diabetes were randomized to receive SR-RYGB or SG at a single centre. Data from the Hospital Anxiety and Depression Scale (HADS), RAND 36-item Health Survey and body weight were collected before surgery and annually for 5 years.

RESULTS

Sixteen patients were lost to follow-up at 5 years. Of the 98 patients who completed 5-year psychological follow-up assessments, 13 had mild to severe depressive symptoms (SR-RYGB n = 6, SG n = 7). SR-RYGB and SG resulted in similar psychological health improvement but percent weight loss at 5 years was greater for SR-RYGB by 10.6% (95% CI: 7.2 to 14.0, P < 0.0001). Scores for depressive symptoms and most RAND-36 domains improved significantly from baseline to 5 years in both groups. Patients with pre-existing depressive symptoms had similar percent weight loss at 5 years compared to patients without depressive symptoms, irrespective of procedural type.

CONCLUSION

Patients receiving either SR-RYGB or SG had comparable psychosocial functioning, which was maintained to 5 years post-surgery. Pre-existing depressive symptoms did not affect weight loss achieved at 5 years. These findings confirm previous longitudinal studies demonstrating that bariatric surgery is generally associated with improved psychosocial functioning.

Self-withdrawal from scheduled bariatric surgery: Qualitative study exploring patient and healthcare provider perspectives

The objective of the study was to explore the experience of patients who self-withdrew from their scheduled bariatric surgery (BS) after completing the lengthy multidisciplinary assessment and optimization process, and to examine how these withdrawals affect healthcare providers (HCPs) in a Bariatric Centre of Excellence (BCoE). Interviews were conducted with patients who self-withdrew, within 1 month, from scheduled BS. Additionally, a focus group with HCPs from the same BCoE was completed. The data were analysed using an inductive, emergent thematic approach with open coding in NVivo 12, with comparative analysis to identify common themes between groups. Eleven patients and 14 HCPs participated. HCPs identified several behavioural and logistical red flags among patients who self-withdrew from scheduled BS. Patients and HCPs felt the decision was appropriate, owing to a patient's lack of mental preparedness for change, social supports, or fears of postoperative complications. HCPs reported frustration and described negative impacts on clinic efficiency. Additional mental health resources for patients contemplating self-withdrawal, such as peer support, were suggested. In conclusion, a patient's decision to self-withdraw from a scheduled BS is often sudden, definite, and associated with anxiety, fear of surgical risks and post-operative complications. Additional mental health resources at a BCoE may be beneficial to support patients at risk of self-withdrawal from scheduled BS.

The impact of psychological distress on weight regain in post-bariatric patients during the COVID-19 pandemic: A latent profile analysis

OBJECTIVE

The COVID-19 pandemic has caused a global health crisis disrupting healthcare delivery for people with severe obesity who have undergone bariatric surgery. This study examined the role of psychological distress during the first Italian COVID-19 lockdown in predicting post-operative outcomes in post-bariatric patients reaching the end of the 12-18 months follow-up during the lockdown. By using a person-centered approach, groups of patients with different psychological distress profiles were identified. We hypothesized that compared to post-bariatric patients with low psychological distress, post-bariatric patients with high psychological distress will be more at risk of weight regain.

METHODS

A total of 67 patients (71.6% female, M_age = 45.9) participated in this observational retrospective cohort study. Patients' anthropometric data were gathered from medical records while the weight at the end of the lockdown through phone interviews. Psychological distress, operationalized with anxiety symptoms, depressive symptoms, and sleep disturbances, was assessed by an online self-report questionnaire.

RESULTS

Significant differences were highlighted in the high and low psychological distressed group in weight changes, F(1,58) = 5.2, p < 0.001, η² = 0.3. Specifically, compared to post-bariatric patients in the low psychological distress group, those in the high psychological distressed group reported weight regained (95% CI = 1.0, 2.6).

CONCLUSION

Results highlight the need to target post-bariatric patients with high psychological distress who are at risk for weight regain during the COVID-19 pandemic. Interventions mitigating psychological distress and obesogenic behaviors during future pandemics or in post-COVID times are needed in vulnerable post-bariatric patients reporting high psychological distress.

Prevalence of adverse childhood experiences and effect on outcomes in bariatric surgery patients: a systematic review and meta-analysis

Adverse childhood experiences (ACEs) are defined as childhood maltreatment (sexual, physical, and emotional abuse and neglect) and other childhood traumatic experiences. Published prevalence estimates for ACEs in bariatric samples vary greatly and evidence on the association between ACEs and bariatric surgery weight loss and psychosocial outcomes is inconclusive. A systematic literature search on PubMed/Medline, PsycInfo, Web of Science, CINAHL (Cumulative Index of Nursing and Allied Health Literature), and Open Grey for studies published until August 30, 2021, yielded 21 publications for qualitative synthesis: 20 reporting on prevalence of ACEs in bariatric surgery candidates and patients, and 10 on the association of ACEs with outcomes. In meta-analysis, overall moderate to high heterogeneity was observed for prevalence estimates and moderate heterogeneity was observed for associations. Prevalence estimate for at least 1 form of ACEs (6 studies, n = 1368 patients) was 51% (95% confidence interval [CI]: 32%-70%). Effect size (Hedge's g) for the difference between the groups of patients reporting any or a high number of ACEs versus no or a low number of ACEs was calculated from means, standard deviations and group size, or P values. Based on 7 studies (n = 946 patients), the association between ACEs and weight loss was not significant (Hedge's g = -.15 [95% CI: -.38 to .09]; I² = 53%), regardless of short- or long-term follow-up (P = .413) and the proportion of patients in each study receiving Roux-en-Y gastric bypass (RYGB) (β = .0005, P = .868). Preliminary findings based on 3 short- and long-term studies (n = 414 patients) showed that ACEs were significantly (P = .001) associated with higher postoperative depressive symptoms (Hedge's g = .50 [95% CI: .22-.78]; I² = 36%). Associations between ACEs and other psychosocial outcomes such as eating pathology were reported narratively. There is a need for additional long-term studies using validated assessment tools for ACEs to evaluate the effect of ACEs on weight and psychosocial outcomes after bariatric surgery.

Obesity and bariatric surgery in adults living with severe mental illness: perceptions and clinical challenges

Overweight and obesity are twice as likely to develop in people living with severe mental illness (SMI), compared with those without. Many factors contribute to this, such as reduced physical activity and the use of certain medications that induce weight gain. Obesity contributes to the premature mortality seen in people living with SMI, as it is one of the fundamental risk factors for cardiovascular disease and diabetes. Bariatric surgery is an effective treatment option, although patients living with SMI might face stigma when being considered for surgical intervention. This article proposes a discussion around obesity and bariatric surgery in patients living with SMI. It will also reflect on the challenges faced by healthcare professionals and patients living with SMI and obesity, when considering appropriate treatments for weight loss. The paper utilises a fictional case, informed by contributions from a lived experience author, to explore bariatric surgery in people living with SMI.

Prevalence and Outcomes of Depression After Bariatric Surgery: A Systematic Review and Meta-Analysis

Surgeons often focus on weight loss and improvement of obesity-related conditions as a primary outcome after bariatric surgery. However, the success of bariatric surgery also relies on the improvement of mental health status. Therefore, the current meta-analysis was carried out to reveal the prevalence of depressive symptoms and their subsequent impact on bariatric surgery outcomes. This study was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist and the recommendation of Cochrane Collaboration. All clinical studies reporting the prevalence and/or the outcomes of depression after bariatric surgery were included in the current meta-analysis. This meta-analysis encompassed 33 articles, including a total of 101,223 patients. The prevalence of post-bariatric surgery depression was 15.3% (95% confidence intervals {CI}: 15.0-15.5%, p<0.001) among which severe, moderate, and minimal depression accounted for 1.9% (95% CI: 1.5-2.4%, p<0.001), 5.1% (95% CI: 4.4-5.8%, p<0.001), and 64.9% (95% CI: 63.3-66.5%, p<0.001), respectively. Depression is negatively correlated with weight loss (correlation -0.135; 95% CI: -0.176 to 0.093; p<0.001) and positively correlated with eating disorder (correlation 0.164; 95% CI: 0.079-0.248; p<0.001). The prevalence of post-bariatric surgery depression is relatively high reaching up to 64.9%, with almost one in five patients affected by it. Depression is associated with weight regain, eating disorders, and quality of life.

Obesity in children and adolescents: epidemiology, causes, assessment, and management

This Review describes current knowledge on the epidemiology and causes of child and adolescent obesity, considerations for assessment, and current management approaches. Before the COVID-19 pandemic, obesity prevalence in children and adolescents had plateaued in many high-income countries despite levels of severe obesity having increased. However, in low-income and middle-income countries, obesity prevalence had risen. During the pandemic, weight gain among children and adolescents has increased in several jurisdictions. Obesity is associated with cardiometabolic and psychosocial comorbidity as well as premature adult mortality. The development and perpetuation of obesity is largely explained by a bio-socioecological framework, whereby biological predisposition, socioeconomic, and environmental factors interact together to promote deposition and proliferation of adipose tissue. First-line treatment approaches include family-based behavioural obesity interventions addressing diet, physical activity, sedentary behaviours, and sleep quality, underpinned by behaviour change strategies. Evidence for intensive dietary approaches, pharmacotherapy, and metabolic and bariatric surgery as supplemental therapies are emerging; however, access to these therapies is scarce in most jurisdictions. Research is still needed to inform the personalisation of treatment approaches of obesity in children and adolescents and their translation to clinical practice.

The Norse Feedback in a population of patients undergoing bariatric surgery-Psychometric properties of a digital computer-adaptive questionnaire assessing mental health

The Norse Feedback (NF) is a questionnaire developed for patient-reported outcome monitoring with a clinical feedback system (PRO/CFS). As mental health is a concern after bariatric surgery, the use of the NF as part of PRO/CFS may be beneficial. The aim of this study is to test the reliability and validity of the NF in patients who have been accepted for or have undergone bariatric surgery. We performed separate robust confirmatory factor analyses (CFAs) to test the unidimensionality on 19 of the NF scales. We also performed correlation analyses on 19 of the NF scales with the Obesity-related Problems scale (OP). We included 213 patients. In the CFA analyses, three out of 12 scales with four or more items showed satisfactory psychometric properties in all goodness of fit indices (Suicidality, Need for Control and Self-Criticism). Four scales showed satisfactory psychometric properties in all indices but RMSEA (Somatic Anxiety, Substance Use, Social Safety and Cognitive Problems). Several of the scales demonstrated floor effects. In the correlation analyses, 18 of the 19 scales showed small-to-moderate correlation coefficients with the OP. Our demonstration of satisfactory psychometric properties on several important scales of the NF suggests that this tool may prove valuable in the routine follow-up of mental health in this population. However, further work is needed to innovate the NF for patients undergoing bariatric surgery.

Experiences of the Bariatric Pre-Surgery Evaluation Process in a National Health Service—An Interpretative Phenomenological Analysis

There is currently little understanding of bariatric patients’ experiences and expectations of the bariatric pre-surgery evaluation (PSE) process. This is especially true for patients within the National Health Service (NHS) in the UK. Consequently, this study undertakes a qualitative study to explore the experiences and expectations of the bariatric PSE amongst patients who had undergone bariatric surgery within the NHS in the UK, using the Interpretative Phenomenological Analysis. Three inter-related superordinate themes were presented: (i) ‘PSE was challenging but essential’, (ii) ‘Coping processes to deal with the PSE’, and (iii) ‘Staff and service evaluation’. Most participants had conflicting feelings about the PSE process as it had both positive and negative impacts on their wellbeing. The process was considered essential for preparation and successful post-surgery adjustment, though the uncertainty of approval was experienced as very distressing. Consequently, participants utilised both external and internal coping strategies, such as social support, researching, or ‘toeing the line’. Participants’ experiences encouraged them to provide feedback about the staff and service, which revealed a preference for a tailored evaluation process. The emerged themes represent an initial framework for helping healthcare providers and researchers to involve patients in service delivery thereby facilitating a patient-centred approach. A starting point is to audit patients’ perspectives routinely. Further investigations are needed to better define, validate, and understand constructs and processes identified in this study.

Nutritional consequences of bariatric surgery - prevention, detection and management

PURPOSE OF REVIEW

Bariatric surgery is an effective treatment option for severe and complex obesity; however, those who undergo such surgery need access to nutritional monitoring and vitamin and mineral supplementation to avoid the development of nutritional deficiencies.

RECENT FINDINGS

The British Obesity and Metabolic Surgery Society and the American Society for Metabolic and Bariatric Surgery have recently updated their recommendations on preoperative and postoperative nutritional monitoring and supplementation. There is a growing interest in the more malabsorptive procedures that are associated with an increased risk of nutritional deficiencies. Nutritional monitoring and prevention of nutritional deficiencies are discussed.Long-term follow-up that includes annual nutritional monitoring and access to a dietetic annual review is recommended; however, in the United Kingdom, many bariatric surgery centres are only commissioned to provide 2 years of follow-up, after which care is transferred to the general practitioner. Consideration should be given to developing shared care models for aftercare and also for the aftercare of malabsorptive procedures to remain with specialist centres.

SUMMARY

Bariatric surgery is a safe and effective treatment option for severe and complex obesity. It is essential that patients have access to lifelong nutritional monitoring adjustment of vitamin and mineral supplements to prevent nutritional issues.

Predictive Role of Body Image in Bulimic Behaviors Among Obese Patients Qualified for Bariatric Surgery

Bulimic behavior and the associated experience of one's own body are of great importance in the course of surgical treatment for obesity. This study determined the predictive role of multidimensional body image on bulimic-type eating behaviors among individuals scheduled for the surgical treatment of obesity. This study was conducted in a clinical setting on a group of 100 obese patients who were treated at the Centre for the Surgical Treatment of Obesity at the University Hospital in Krakow (Poland) and were qualified for bariatric surgery. Body image was examined with Cash's Multidimensional Body-Self Relations Questionnaire (MBSRQ) and bulimic behavior with David M. Garner's Eating Attitudes Test (EAT-26). Part A of the EAT-26 focused only on the bulimia and food preoccupation scale. Part B included sex, age, and body mass index (BMI) in the predictive model. A stepwise multiple regression analysis was conducted to assess psychological predictors of eating behavior. For binary variables, a logistic regression analysis was conducted for the whole group and for the women's group alone. Owing to the small sample size of men, regression analyses were not conducted. Higher values were observed in the Appearance Orientation dimension among women when compared to men. Appearance evaluation and age were found to be significant predictors for bulimic behaviors in the whole group. In regression models for behavior in the last 6 months, the predictors were found to be Health Evaluation and Appearance Orientation for laxative use, and Overweight Preoccupation for vomiting for weight control. Health-promoting behaviors in obesity treatment were conditioned as follows: for exercise, the predictors were sex and Fitness Orientation and for weight loss, they were Overweight Preoccupation and Body Areas Satisfaction. Our study shows that different bulimic behaviors are variously conditioned by body image dimensions, some of which are predictors of behaviors that are risk factors for obesity and poor outcomes of bariatric treatment, whereas others increase the chance of pro-health behaviors among obese individuals.

Developing Integrated Clinical Pathways for the Management of Clinically Severe Adult Obesity: a Critique of NHS England Policy

PURPOSE OF THE REVIEW

Pathways for obesity prevention and treatment are well documented, yet the prevalence of obesity is rising, and access to treatment (including bariatric surgery) is limited. This review seeks to assess the current integrated clinical pathway for obesity management in England and determine the major challenges.

RECENT FINDINGS

Evidence for tier 2 (community-based lifestyle intervention) and tier 3 (specialist weight management services) is limited, and how it facilitates care and improve outcomes in tier 4 remains uncertain. Treatment access, rigidity in pathways, uncertain treatment outcomes and weight stigma seems to be major barriers to improved care. More emphasis must be placed on access to effective treatments, treatment flexibility, addressing stigma and ensuring treatment efficacy including long-term health outcomes. Prevention and treatment should both receive significant focus though should be considered to be largely separate pathways. A simplified system for weight management is needed to allow flexibility and the delivery of personalized care including post-bariatric surgery care for those who need it.

The Optimal Nutritional Programme for Bariatric and Metabolic Surgery

PURPOSE OF REVIEW

Bariatric surgery is the most effective treatment for severe and complex obesity; however, the risk of developing nutrient deficiencies varies based upon the type of surgery, degree of malabsorption, and level of nutrition intervention. There are numerous factors that can impact the nutrition status of a patient during their pre- and postoperative journey. We review the critical components and considerations needed in order to provide optimal nutrition care for patients with bariatric surgery.

RECENT FINDINGS

A dietitian, specializing in bariatric surgery, is the best equipped healthcare provider to prepare and support patients in achieving and maintaining optimal nutrition status. We present best practices for both the pre- and postoperative nutrition-related phases of a patient's journey. The dietitian specialist is integral in the assessment and ongoing nutrition care of patients with bariatric surgery. Further consideration should be given to enable access for lifelong follow-up and monitoring.

Health-Related Quality of Life in Bariatric and Metabolic Surgery

PURPOSE OF REVIEW

This review describes the latest evidence for the impact of bariatric surgery on health-related quality of life (HRQL).

RECENT FINDINGS

The impact of bariatric surgery on HRQL is less well-understood than its clinical effectiveness on weight and co-morbidities. Poor-quality study design and different HRQL measures challenge systematic reviews and meta-analyses. Available limited evidence suggests that physical aspects of HRQL may improve more than mental health aspects of HRQL after bariatric surgery, reaching maximal benefits 1-2 years post-surgery. Comparative HRQL analyses between bariatric procedures cannot be made due to a lack of randomised data. Qualitative research highlights the tensions patients experience after bariatric surgery, which provides insights to observed changes in HRQL. Standardized HRQL measures are being developed and agreed to improve future evidence synthesis. Two multi-centre randomised trials of bariatric surgical procedures including detailed HRQL assessment are in progress. It is hoped that the combination of comparative high-quality HRQL data and information from qualitative studies will provide new insights into patient well-being and health after bariatric surgery.

Exploring the Experiences of Women Who Develop Restrictive Eating Behaviours After Bariatric Surgery

OBJECTIVE

This study aimed to explore the experiences of women who had developed excessively restrictive eating behaviours following bariatric surgery.

METHOD

Five female participants, who were at least nine months post-bariatric surgery and exhibiting restrictive eating behaviours, were recruited from Bariatric Surgery Psychology Services and asked to complete qualitative face-to-face semi-structured interviews. The data was analysed using interpretative phenomenological analysis (IPA).

RESULTS

Three super-ordinate themes emerged: (1) experiences of weight stigma and weight history on self, (2) the impact of loose skin, (3) thoughts about food and disordered eating patterns. These captured the impact of past weight-related experiences-including weight stigma, intense fears of weight gain, negative cognitions about the self, the impact of excess skin, changes in the way the women thought about food and restrictive eating behaviours.

DISCUSSION

This study is one of the first to specifically explore restrictive eating disorders after bariatric surgery using a qualitative approach. The findings of this study may offer helpful aspects for professionals to hold in mind when identifying individuals with problematic restrictive eating behaviours following bariatric surgery. Body contouring surgery, internalised weight bias and weight stigma are explored in relation to the post-bariatric surgery treatment pathway. The current diagnostic criterion for anorexia nervosa are discussed to highlight difficulties in diagnosing this presentation in the post-bariatric surgery population, where people can have BMIs over 25 kg/m2 but are severely restricting energy intake.

Patients' experiences of life after bariatric surgery and follow-up care: a qualitative study

OBJECTIVES

Bariatric surgery is the most clinically effective treatment for people with severe and complex obesity, however, the psychosocial outcomes are less clear. Follow-up care after bariatric surgery is known to be important, but limited guidance exists on what this should entail, particularly related to psychological and social well-being. Patients' perspectives are valuable to inform the design of follow-up care. This study investigated patients' experiences of life after bariatric surgery including important aspects of follow-up care, in the long term.

DESIGN

A qualitative study using semistructured individual interviews. A constant comparative approach was used to code data and identify themes and overarching concepts.

SETTING

Bariatric surgery units of two publicly funded hospitals in the South of England.

PARTICIPANTS

Seventeen adults (10 women) who underwent a primary operation for obesity (mean time since surgery 3.11 years, range 4 months to 9 years), including Roux-en-Y gastric bypass, adjustable gastric band and sleeve gastrectomy, agreed to participate in the interviews.

RESULTS

Experiences of adapting to life following surgery were characterised by the concepts of 'normality' and 'ambivalence', while experiences of 'abandonment' and 'isolation' dominated participants' experiences of follow-up care. Patients highlighted the need for more flexible, longer-term follow-up care that addresses social and psychological difficulties postsurgery and integrates peer support.

CONCLUSIONS

This research highlights unmet patient need for more accessible and holistic follow-up care that addresses the long-term multidimensional impact of bariatric surgery. Future research should investigate effective and acceptable follow-up care packages for patients undergoing bariatric surgery.
