Abstract
PURPOSE OF REVIEW Pediatric obesity is a growing concern globally. Patients with a history of overweight/obesity often experience stigmatization, especially in the healthcare setting, and are at increased risk of developing psychological comorbidities including eating disorders. This review appraises the most recent studies evaluating eating disorder risk in youth undergoing treatment for obesity, identifies gaps in the literature, and offers practical guidelines to pediatric providers regarding the management of this population. RECENT FINDINGS Recent studies suggest that structured weight management programs may decrease the risk of and/or improve symptoms of certain eating disorders such as binge eating disorder and bulimia nervosa. There is a paucity of research on some components of obesity management such as obesity pharmacotherapeutics and eating disorder risk. SUMMARY Children and adolescents with obesity are a psychologically vulnerable population with increased risk for the development of eating disorders. Further study is needed to evaluate general risk in the setting of specialized and primary care obesity interventions and develop appropriate screening and mitigation tools. Some evidence-based strategies can aid pediatric providers in both weight management and eating disorder prevention and risk assessment.

A systematic review with meta-analyses. Eat Weight Disord 2023; 28:89. [PMID: 37889364 PMCID: PMC10611631 DOI: 10.1007/s40519-023-01613-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Accepted: 10/15/2023] [Indexed: 10/28/2023] Open
Abstract
OBJECTIVES This systematic review aimed to compare the weight change in people with or without binge eating who underwent various weight loss treatments. METHODS We searched for studies in PubMed, American Psychological Association, and Embase from inception to January 2022. The studies selected included assessment of binge eating and body weight before and after weight loss treatment in people of any age. The meta-analyses were conducted using Comprehensive Meta-Analysis (CMA). We used Egger's regression test, the funnel plot, and the Trim and Fill test to assess the risk of publication bias. RESULTS Thirty-four studies were included in the systematic review, with a total of 10.184 participants. The included studies were divided into three categories according to types of weight loss treatments, namely, (1) bariatric surgery; (2) pharmacotherapy isolated or combined with behavioral interventions; and (3) behavioral and/or nutritional interventions. The meta-analyses showed no significant difference in weight loss between people with or without binge eating engaged in weight loss treatments, with an overall effect size of - 0.117 (95% CI - 0.405 to 0.171; P = 0.426). CONCLUSIONS Our findings showed no difference in weight loss in people with or without pre-treatment binge eating who received various weight loss treatments. Weight loss treatments should not be withheld on the basis that they will not be effective in people with pre-treatment binge eating, albeit their safety and longer term impacts are unclear. LEVEL OF EVIDENCE Level I, at least one properly designed randomized controlled trials; systematic reviews and meta-analyses; experimental studies.

Klapsas M, Hindle A. Patients' Pre and Post-Bariatric Surgery Experience of Dieting Behaviours: Implications for Early Intervention. Obes Surg 2023; 33:2702-2710. [PMID: 37468701 DOI: 10.1007/s11695-023-06689-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2022] [Revised: 06/13/2023] [Accepted: 06/16/2023] [Indexed: 07/21/2023]
Abstract
PURPOSE Bariatric surgery works, in part, by surgically changing signals of hunger and satiety to achieve weight loss. Not all patients experience optimal outcomes. One potential explanation is that post-surgery dieting may subvert the ability to identify physiological cues of hunger and fullness. Dieting behaviours (e.g. restriction/cognitive restraint) are correlated with disordered eating, and disordered eating implicated in poor outcomes. This study examines the experience of dieting after bariatric surgery. METHOD Seventeen adult participants who had undertaken bariatric surgery and residing in Australia participated in semi-structured interviews. Surgeries occurred in 2021 (n = 8), 2020 (n = 4), 2019 (n = 2), and one participant each had surgery in 2014, 2009, and 2004. Thematic analysis elicited themes related to post-operative dieting. RESULTS All participants reported chronic pre-surgery dieting. Lifestyle change was the overarching post-surgical theme comprising (i) flexibility (e.g. allowing food, intuitive eating), and (ii) control, comprising surgery control (e.g. set portions, surgery instilled control) and dieting control (e.g. discipline, restriction/restraint). Descriptions of lifestyle change often mirrored pre-surgery descriptions of dieting. CONCLUSION Post-surgery lifestyle change appears to encompass a tension between flexible/adaptive approaches to eating and the need to maintain control. Control may emerge as practices that mirror pre-surgery dieting with the potential to interfere with adaptive eating behaviours or promote disordered eating. Dieting behaviours may be a precursor to the development of disordered eating. Health care practitioners should regularly assess dieting behaviour post-surgery to enable early intervention where warranted. Future research should consider how post-surgery re-emerging dieting may be identified and measured to aid in intervention.

[PMID: 36252389 DOI: 10.1016/j.eatbeh.2022.101677] [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: 01/29/2022] [Revised: 09/30/2022] [Accepted: 10/01/2022] [Indexed: 11/26/2022]
Abstract
BACKGROUND Weight-regain is commonly experienced after bariatric surgery. This qualitative enquiry aimed to explore participants' self-reported enablers and barriers to prevent future weight-regain post-surgery. METHODS Eligible adults were recruited at 12-months post-bariatric-surgery at Counties Manukau, Auckland. Participants were invited to attend data collection at their 18-month group nutrition-education session, and to participate in a focus group at 21-months post-surgery. Thematic analysis was used to evaluate patient experiences. RESULTS Participants (n = 28) were mostly female (73.2 %), New Zealand European (41.5 %), and had gastric sleeve surgery (92.3 %). Five key themes emerged from the analysis: A Life Changing Health Journey - participants experienced a decrease in obesity-related comorbidities and a subsequent decrease in medications. Weight change and food intolerances impacted quality of life. Challenge of managing a New Healthy Lifestyle - financial stress, buying healthier foods and social events were new challenges, often centred on food. Changing Eating Behavior - all participants struggled managing eating behaviors. Mindset Changes - post-surgery most participants had a positive mindset, increased confidence, and feelings of happiness. However, many struggled with mindset around weight and food. A need for On-going Support - most felt under-supported and expressed a need for longer, specific follow-up care. CONCLUSION Post-surgery group education sessions provided participants with increased support from both health professionals and peers on the same journey, to overcome struggles such as binge eating or identifying new coping strategies. Findings provide important insights into the challenges patients with bariatric surgery face and key learnings to develop specific supports for future care practices.

Body Image and Body Mass Index Influence on Psychophysical Well-Being in Bariatric Patients: A Cross-Sectional Study. J Pers Med 2022; 12:jpm12101597. [PMID: 36294736 PMCID: PMC9604850 DOI: 10.3390/jpm12101597] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Revised: 09/20/2022] [Accepted: 09/26/2022] [Indexed: 11/23/2022] Open
Abstract
Background: Psychophysical factors may have an impact on the disease of obesity, and it is important to explore which aspects may play an important role on the well-being of obese patients undergoing bariatric surgery. The purpose of this study was to assess the associations of a high body mass index (BMI) and greater dissatisfaction with body image with higher levels of psychopathological aspects, feelings of hopelessness, and psychological and physical health in patients undergoing evaluation for bariatric surgery. Methods: Fifty-nine patients undergoing bariatric surgery filled out the Symptom Checklist-90-Revised, the Body Uneasiness Test, the 12-item Short Form Survey, the Beck Inventory Scale II, and the Beck Hopelessness Scale. Correlations and hierarchical regressions between measures were performed. Results: Dissatisfaction with the perception of one’s own body image was strongly correlated with a worse psychophysiological health. On the contrary, BMI showed no significant correlation with the previous variables. Furthermore, the perception of one’s own body image significantly predicted the state of psychological health. Conclusions: The findings showed a more relevant role of body image compared to the BMI in the association with psychological outcomes, suggesting the importance of considering body image in the assessment and treatment of obese patients requiring bariatric treatment.

Abstract
IMPORTANCE Individuals with severe obesity presenting for obesity surgery (OS) frequently show nonnormative eating behaviors (NEBs) and eating disorders (EDs), but the long-term course and prospective associations with weight loss and health-related quality of life (HRQOL) remain unclear. OBJECTIVE To examine the prevalence and prospective relevance of presurgical and postsurgical NEBs and EDs according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, diagnosed through clinical interview, for weight loss and HRQOL up to 6 years following OS. DESIGN, SETTING, AND PARTICIPANTS In the prospective, multicenter Psychosocial Registry for Obesity Surgery cohort study, patients seeking OS were recruited at 6 OS centers in Germany and assessed at baseline before surgery and at 6 months and 1 to 6 years after surgery. From a consecutive sample of 1040 volunteers with planned OS from March 1, 2012, to December 31, 2020, a total of 748 (71.92%) were included in this study. Across follow-up, 93 of the 748 patients (12.43%) dropped out. Data were analyzed from April to November 2021. INTERVENTIONS Laparoscopic Roux-en-Y gastric bypass or sleeve gastrectomy. MAIN OUTCOMES AND MEASURES Both NEBs and EDs were identified using the Eating Disorder Examination interview. Main outcomes were the percentage of total body weight loss (%TBWL) and HRQOL (Impact of Weight on Quality of Life-Lite; range, 0-100, with 0 indicating worst and 100 indicating best). RESULTS In 748 patients undergoing OS (mean [SD] age, 46.26 [11.44] years; mean [SD] body mass index [calculated as weight in kilograms divided by height in meters squared], 48.38 [8.09]; 513 [68.58%] female), the mean (SD) %TBWL was 26.70% (9.61%), and the mean (SD) HRQOL improvement was 35.41 (20.63) percentage points across follow-up. Both NEBs and EDs were common before surgery, with postsurgical improvements of varying degrees. Whereas NEBs and EDs did not reveal significant prospective associations with %TBWL, loss-of-control eating at follow-up was concurrently associated with lower %TBWL (estimate, -0.09; 95% CI, -0.14 to -0.04). Loss-of-control eating (estimate, -0.10; 95% CI, -0.17 to -0.03 percentage points) and binge-eating disorder of low frequency and/or limited duration (estimate, -6.51; 95% CI, -12.69 to -0.34 percentage points) at follow-up showed significant prospective associations with lower HRQOL. CONCLUSIONS AND RELEVANCE This cohort study found prospective relevance of loss-of-control eating and binge-eating disorder of low frequency and/or limited duration for reduced long-term HRQOL following OS. These findings underline the importance of monitoring both NEBs, especially loss-of-control eating, and EDs in the long term postsurgically to identify patients in need of targeted prevention or psychotherapy.

Abstract
This systematic review evaluated the dietary experience of patients with obesity post-bariatric surgery. Scopus, CINAHL, Medline, Psych INFO, and Embase databases were searched and JBI Critical Appraisal Tool was used for quality assessment. Thomas and Harden's three-stage thematic synthesis was undertaken using the Enhancing transparency in reporting the synthesis of qualitative research (ENTREQ) statement for reporting. Of the 24 studies extracted, we coded and developed 34 descriptive themes into 7 categories, which were then categorized to 3 analytical themes. The number of all the participants in the 24 articles is 383 people. The results revealed most patients can control their diet for a short period post-surgery. However, this was a matter of gradual self-consciousness as patients also required support and dietary management in postoperative recovery. CLINICAL TRIAL REGISTRATION NUMBER: The protocol for this qualitative systematic review has been registered with PROSPERO (registration number CRD42021229083).

Abstract
Obesity is highly stigmatized, and individuals who undergo bariatric surgery are subject not only to weight stigma, but also to stigma related to the procedure itself. Patients lost to follow-up after surgery make estimating the amount of regain occurring after surgery difficult, and often patients fail to follow up due the shame of weight regain. Patients report difficulty following the diet necessary to maintain weight loss. Additionally, when they seek support after surgery, they often encounter stigmatizing messaging related to weight. Weight bias internalization, weight stigma, and stigma about having the surgery all contribute to feelings of social isolation, disordered eating, and reduced motivation to engage in physical activity. In this chapter, we present evidence for the impact of stigma on bariatric surgery outcomes and discuss the behavioral, physiological, and emotional processes that contribute to weight regain.

Abstract
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.

Abstract
The excitation of vagal mechanoreceptors located in the stomach wall directly contributes to satiation. Thus, a loss of gastric innervation would normally be expected to result in abrogated satiation, hyperphagia, and unwanted weight gain. While Roux-en-Y-gastric bypass (RYGB) inevitably results in gastric denervation, paradoxically, bypassed subjects continue to experience satiation. Inspired by the literature in neurology on phantom limbs, I propose a new hypothesis in which damage to the stomach innervation during RYGB, including its vagal supply, leads to large-scale maladaptive changes in viscerosensory nerves and connected brain circuits. As a result, satiation may continue to arise, sometimes at exaggerated levels, even in subjects with a denervated or truncated stomach. The same maladaptive changes may also contribute to dysautonomia, unexplained pain, and new emotional responses to eating. I further revisit the metabolic benefits of bariatric surgery, with an emphasis on RYGB, in the light of this phantom satiation hypothesis.

Abstract
INTRODUCTION While body image can improve following bariatric surgery, a portion of patients continue to experience concerns about weight and shape regardless of weight lost. Research is needed to identify risk factors for post-surgical weight and shape concerns given that body dissatisfaction may contribute to poor outcomes. AIMS To evaluate whether (1) change in weight-related self-esteem and symptoms of depression from pre- to 12-month post-surgery were associated with change in weight and shape concerns independent of weight-loss; (2) improvement in weight and shape concerns, symptoms of depression, and/or weight-related self-esteem predict greater weight-loss 12 months after bariatric surgery; and (3) improvements in weight-related self-esteem, symptoms of depression, weight concerns, or shape concerns predict weight loss. METHODS Fifty adults approved to receive bariatric surgery self-reported body mass index and completed validated measures of weight-related self-esteem, symptoms of depression, and weight and shape concerns pre- and 12-month post-surgery. RESULTS Improvements were observed for weight-related self-esteem, concerns over shape and weight, symptoms of depression, and body mass index from pre- to 12-month post-surgery. Improvement in weight-related self-esteem was associated with concomitant improvements in concerns over shape and weight, independent of weight loss. Improvement in symptoms of depression was associated with improvement in concerns over weight, but not shape. Finally, exploratory analyses indicated that improvements in weight-related self-esteem, and concerns over shape and weight, but not symptoms of depression were associated with improvement in weight-loss. CONCLUSIONS Weight-related self-esteem may represent an overlooked and important target throughout the bariatric surgery process that could enhance surgical outcomes.
