Nutrients 2024; 16:1068.

Abstract
This study aimed to examine the potential predictors of improvement in mental health outcomes following participation in an intensive non-surgical outpatient weight management program (WMP) in an Australian public hospital. This was a retrospective cohort study of all adults with Class 3 obesity (BMI ≥ 40 kg/m2) who enrolled in the WMP from March 2018 to June 2021. The participants completed the Eating Disorder Examination Questionnaire Short Version (EDE-QS), Kessler-10 Psychological Distress Scale, and 36-Item Short-Form Survey (SF-36) at baseline and 12-month follow-up. A total of 115 patients completed 12 months in the WMP and were included in the study, with 76.5% being female, a mean ± SD age at baseline of 51.3 ± 13.8 years, a weight of 146 ± 26 kg, and a BMI of 51.1 ± 8.6 kg/m2. The participants lost an average of 8.6 ± 0.2 kg over 12 months, and greater weight loss at follow-up was significantly associated with improved global EDE-QS scores, psychological distress, and improved mental health quality of life. However, improvements in most mental health outcomes were not predicted by weight loss alone. Notably, a lower eating disorder risk at baseline was associated with less psychological distress at follow-up and greater weight loss at follow-up. Our results also found an association between reduced psychological distress and reduced binge eating frequency. These findings support the inclusion components of obesity interventions that target the psychological correlates of obesity to support improved outcomes in people with Class 3 obesity. Future studies should aim to identify which aspects of the WMP helped improve people's psychological outcomes.

Screening, assessment and diagnosis in the eating disorders: findings from a rapid review. J Eat Disord 2022; 10:78. [PMID: 35672777 PMCID: PMC9175461 DOI: 10.1186/s40337-022-00597-8] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2022] [Accepted: 05/21/2022] [Indexed: 11/27/2022] Open
Abstract
BACKGROUND Limited screening practices, minimal eating disorder training in the healthcare professions, and barriers related to help-seeking contribute to persistent low rates of eating disorder detection, significant unmet treatment need, and appreciable associated disease burden. The current review sought to broadly summarise the literature and identify gaps relating to the screening, assessment, and diagnosis of eating disorders within Western healthcare systems. METHODS This paper forms part of a Rapid Review series scoping the evidence base for the field of eating disorders, conducted to inform the Australian National Eating Disorders Research and Translation Strategy 2021-2031, funded and released by the Australian Government. ScienceDirect, PubMed and Ovid/Medline were searched for studies published between 2009 and mid 2021 in English. High-level evidence such as meta-analyses, large population studies and Randomised Control Trials were prioritised through purposive sampling. Data from selected studies relating to Screening, Assessment and Diagnosis of eating disorders were synthesised and are disseminated in the current review. RESULTS Eighty seven studies were identified, 38% relating to screening and 62% to assessment and diagnosis. The majority of screening studies were conducted in university student samples, showing high prevalence but only modest improvements in help-seeking in those studies that followed up post-screen. In healthcare settings, clinicians continue to have difficulty identifying eating disorder presentations, particularly Binge Eating Disorder, Other Specified Feeding or Eating Disorders, and sub-threshold eating disorders. This is preceded by inadequate and frequently homogenous screening mechanisms and exacerbated by considerable personal and health-system barriers, including self-stigma and lack of resourcing. While all groups are at risk of delayed or no diagnosis, those at particular risk include LGBTQ+ and gender diverse individuals, individuals living in larger bodies, and males. CONCLUSIONS A majority of individuals with eating disorders remain undiagnosed and untreated despite a high prevalence of these conditions and increased advocacy in recent years. Research into improving detection and clinician diagnostic skill is extremely limited. Innovative empirical research is strongly recommended to address significant individual and health-system barriers currently preventing appropriate and timely intervention for many. Limited screening in healthcare settings and low rates of eating disorder training in the healthcare professions are just some of the barriers to help-seeking which may contribute to delayed intervention and diagnosis in the eating disorders. This has significant impacts, prolonging treatment when it is finally received, and increasing healthcare costs for both the individual and the healthcare system. The current review is part of a larger Rapid Review series conducted to inform the development of Australia's National Eating Disorders Research and Translation Strategy 2021-2031. A Rapid Review is designed to comprehensively summarise a body of literature in a short timeframe, often to guide policy-making and address urgent health concerns. The Rapid Review synthesises the current evidence-base and identifies gaps in eating disorder research and care, in order to guide decision making and address urgent health concerns. This paper gives a critical overview of the scientific literature relating to the current state of screening, assessment, and diagnosis of eating disorders within Western healthcare systems that may inform health policy and research in an Australian context. It covers screening initiatives in both general and high-risk populations; personal, clinician and healthcare system challenges relating to help-seeking; and obstacles to accurate and timely clinical diagnosis across the eating disorders.

Abstract
Overvaluation of shape and weight (OSW), or self-evaluation based primarily on body shape and weight, is associated with cognitive and behavioral aspects of eating disorders (including dietary restraint; concerns about eating, shape, and weight; and loss of control eating (LOC-eating), as well as psychological distress. We explored associations among OSW, depressive symptoms, and various forms of eating-related psychopathology, including whether frequency of LOC-eating mediates observed associations, among 88 bariatric surgery candidates. OSW was positively correlated with LOC-eating frequency, eating-related psychopathology, and depressive symptoms. There was a direct effect of OSW on depressive symptoms and eating-related psychopathology. LOC-eating frequency partially mediated the association between OSW and eating-related psychopathology. These findings demonstrate that OSW is important to assess as a marker of psychosocial distress.

Abstract
BACKGROUND Eating pathologies among bariatric surgery candidates are common and associated with adverse surgical outcomes, including weight regain and low quality of life. However, their assessment is made difficult by the great variety and inconsistent use of standardized measures. OBJECTIVE The purpose of this review was to synthesize current knowledge on the prevalence of binge eating disorder (BED) in presurgical patients and to make a critical appraisal of assessment tools for BED. METHODS A search was conducted on PubMed, Scopus, and Web of Science databases from January 1994 to March 2017. Data were extracted, tabulated and summarized using a narrative approach. RESULTS A total of 21 observational studies were reviewed for data extraction and analysis. Prevalence of BED in bariatric populations ranged from 2% to 53%. Considerable variation in patient characteristics and in BED assessment measures was evident among the studies. In addition, several methodological weaknesses were recognized in most of the studies. Ten different psychometric instruments were used to assess BED. Clinical interviews were used in only 12 studies, though this is the preferred tool to diagnose BED. CONCLUSION Study heterogeneity accounted for the variability of the results from different centers and methodological flaws such as insufficient sample size and selection bias impaired the evidence on the magnitude of BED in surgical settings. For the sake of comparability and generalizability of the findings in future studies, researchers must recruit representative samples of treatment-seeking candidates for bariatric surgery and systematically apply standard instruments for the assessment of BED.

Attribution of weight regain to emotional reasons amongst European adults with overweight and obesity who regained weight following a weight loss attempt. Eat Weight Disord 2019; 24:351-361.

Abstract
PURPOSE Despite the wide availability of effective weight loss programmes, maintenance of weight loss remains challenging. Difficulties in emotion regulation are associated with binge eating and may represent one barrier to long-term intervention effectiveness in obesity. The purpose of this study was to determine the relationship between emotion regulation difficulties and the extent of weight regain in a sample of adults who had lost, and then regained, weight, and to examine the characteristics associated with emotional difficulties. METHODS 2000 adults from three European countries (UK, Portugal, and Denmark) completed an online survey assessing self-reported weight loss and regain following their most recent weight loss attempt. They also completed a binge eating disorder screening questionnaire and, if they had regained weight, were asked if they attributed it to any emotional factors (a proxy for emotion regulation difficulties). Spearman's correlations and logistic regression were used to assess the associations between emotion regulation, weight regain, and strategy use. RESULTS Emotion regulation difficulties were associated with greater weight regain (N = 1594 who lost and regained weight). Attribution to emotional reasons was associated with younger age, female gender, loss of control and binge eating, lower perceptions of success at maintenance, using more dietary and self-regulatory strategies in weight loss, and fewer dietary strategies in maintenance. CONCLUSIONS Weight-related emotion regulation difficulties are common amongst regainers and are associated with regaining more weight. Affected individuals are already making frequent use of behavioural strategies during weight loss, but do not apply these consistently beyond active attempts. Simply encouraging the use of more numerous strategies, without concurrently teaching emotion regulation skills, may not be an effective means to improving weight outcomes in this group.

Abstract
Bariatric surgery has serious implications on metabolic health. The reasons for a failure of bariatric surgery, i.e., limited weight loss, are multifactorial and include psychological factors. We established a theoretical model of how impulsivity is related to weight loss outcome. We propose that depressive symptoms act as a mediator between impulsivity and pathological eating behavior, and that pathological eating behavior has a direct impact on weight loss outcome. We calculated excessive weight loss (%EWL) and assessed self-reported impulsivity (using the Baratt Impulsiveness Scale (BIS-15) total score), depressive symptoms (the Patient Health Questionnaire (PHQ-9) score), and pathological eating behavior (the Eating Disorder Inventory 2 (EDI-2) total score) in 65 patients four years after laparoscopic sleeve gastrectomy. Regression and mediation analyses were computed to validate the theoretical model. The BIS-15, PHQ-9, and EDI-2 have medium to high correlations between each other, and EDI-2 correlated with %EWL. The mediation analysis yielded that the PHQ-9 represents a significant mediator between BIS-15 and EDI-2. The regression model between EDI-2 and %EWL was also significant. These results support our theoretical model, i.e., suggest that impulsivity has an indirect impact on weight loss outcome after bariatric surgery, mediated by depression and transferred through pathological eating behavior. Thus, the underlying psychological factors should be addressed in post-operative care to optimize weight loss outcome.

Abstract
RESUMO Objetivo Realizar revisão sobre transtornos alimentares e comportamentos alimentares transtornados relacionados à cirurgia bariátrica. Métodos Revisão integrativa da literatura nas bases de dados PubMed, Lilacs, Bireme, portal SciELO com descritores indexados com critérios de inclusão: oferecer dado sobre a presença ou frequência de transtorno alimentar e/ou comportamentos alimentares disfuncionais previamente e/ou após a cirurgia. Resultados Foram selecionados 150 estudos (14 nacionais e 136 internacionais): 80,6% eram com avaliação de pacientes pré-/pós-cirúrgicos; 12% eram estudos de caso e 7,3% eram estudos de revisão. Diferentes instrumentos foram usados para avaliação, principalmente o Questionnaire on Eating and Weight Patterns, a Binge Eating Scale e Eating Disorders Examination Questionnaire. A compulsão alimentar foi o comportamento mais avaliado, com frequências/prevalências variando de 2% a 94%; no caso do transtorno da compulsão alimentar as frequências/prevalências variaram de 3% a 61%. Houve também a descrição de anorexia e bulimia nervosa, síndrome da alimentação noturna e comportamento beliscador. Alguns estudos apontam melhora dos sintomas no pós-cirúrgico e/ou seguimento enquanto outros apontam surgimento ou piora dos problemas. Conclusão Apesar da variabilidade entre métodos e achados, comportamentos alimentares disfuncionais são muito frequentes em candidatos à cirurgia bariátrica e podem ainda surgir ou piorar após a intervenção cirúrgica. Profissionais de saúde devem considerar de maneira mais cuidadosa tais problemas neste público, dadas às consequências para o resultado cirúrgico e qualidade de vida.

Abstract
Binge-eating disorder is a common psychiatric disorder affecting ~2% of adults. Binge-eating was initiated in freely-fed, lean, adult, female rats by giving unpredictable, intermittent access to ground, milk chocolate over four weeks. The rats avidly consumed chocolate during 2 hr binge sessions, with compensatory reductions of normal chow intake in these sessions and the days thereafter. Bodyweights of binge-eating rats were normal. The model's predictive validity was explored using nalmefene (0.1-1.0mg/kg), R-baclofen (1.0-10mg/kg) and SB-334867 (3.0-30 mg/kg) (orexin-1 antagonist), which all selectively decreased chocolate bingeing without reducing chow intake. Sibutramine (0.3-5.0mg/kg) non-selectively reduced chocolate and chow consumption. Olanzapine (0.3-3.0mg/kg) was without effect and rolipram (1.0-10mg/kg) abolished all ingestive behaviour. The pro-drug, lisdexamfetamine (LDX; 0.1-1.5mg/kg), dose-dependently reduced chocolate bingeing by ⩽ 71% without significantly decreasing normal chow intake. Its metabolite, D-amphetamine (0.1-1.0mg/kg), dose-dependently and preferentially decreased chocolate bingeing ⩽ 56%. Using selective antagonists to characterize LDX's actions revealed the reduction of chocolate bingeing was partially blocked by prazosin (α1-adrenoceptor; 0.3 and 1.0mg/kg) and possibly by SCH-23390 (D1; 0.1mg/kg). RX821002 (α2-adrenoceptor; 0.1 and 0.3mg/kg) and raclopride (D2; 0.3 and 0.5mg/kg) were without effect. The results indicate that LDX, via its metabolite, d-amphetamine, reduces chocolate bingeing, partly by indirect activation of α1-adrenoceptors and perhaps D1 receptors.

Abstract
This narrative review provides an overview of the epidemiology of binge eating disorder (BED), highlighting the medical history of this disorder and its entry as an independent condition in the Feeding and Eating Disorders section of the recently published Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. Estimates of prevalence are provided, as well as recognition that the female to male ratio is lower in BED than in other eating disorders. Evidence is also provided of the most common comorbidities of BED, including mood and anxiety disorders and a range of addiction disorders. In addition, discussion of the viewpoint that BED itself may be an addiction - at least in severe cases - is presented. Although the genetic study of BED is still in its infancy, current research is reviewed with a focus on certain neurotransmitter genes that regulate brain reward mechanisms. To date, a focal point of this research has been on the dopamine and the μ-opioid receptor genes. Preliminary evidence suggests that a predisposing risk factor for BED may be a heightened sensitivity to reward, which could manifest as a strong dopamine signal in the brain's striatal region. Caution is encouraged, however, in the interpretation of current findings, since samples are relatively small in much of the research. To date, no genome-wide association studies have focused exclusively on BED.

Abstract
OBJECTIVE To describe eating patterns, prevalence of problematic eating behaviors, and determine factors associated with binge eating disorder (BED), before bariatric surgery. METHOD Before surgery, 2,266 participants (median age 46 years; 78.6% female; 86.9% white; median body mass index 45.9 kg/m(2) ) of the Longitudinal Assessment of Bariatric Surgery-2 (LABS-2) study completed eating behavior survey items in the self-administered LABS-2 Behavior form. Other measures included the Alcohol Use Disorder Identification Test, the LABS-2 Psychiatric and Emotional Test Survey, the Beck Depression Inventory, the Interpersonal Support Evaluation List-12, the Short Form-36 Health Survey, and Impact of Weight Quality of Life-Lite Survey. RESULTS The majority (92.1%) of participants reported eating dinner regularly, whereas just over half (54.0%) reported eating breakfast regularly. Half of the participants reported eating at least four meals/week at restaurants; two meals/week were fast food. Loss of control eating was reported by 43.4%, night eating syndrome by 17.7%; 15.7% satisfied criteria for binge eating disorder (BED), 2% for bulimia nervosa. Factors that independently increased the odds of BED were being a college graduate, eating more times per day, taking medication for psychiatric or emotional problems, and having symptoms of alcohol use disorder, lower self-esteem and greater depressive symptoms. DISCUSSION Before undergoing bariatric surgery a substantial proportion of patients report problematic eating behaviors. Several factors associated with BED were identified, most suggesting other mental health problems, including higher levels of depressive symptomotology. The strengths of this study include the large sample size, the multi-center design and use of standardized assessment practices.

Abstract
PURPOSE To perform a systematic review on the epidemiology, the health-related quality of life (HRQoL) and economic burden of binge eating disorder (BED). METHODS A systematic literature search of English-language articles was conducted using Medline, Embase, PsycINFO, PsycARTICLES, Academic Search Complete, CINAHL Plus, Business Source Premier and Cochrane Library. Literature search on epidemiology was limited to studies published between 2009 and 2013. Cost data were inflated and converted to 2012 US$ purchasing power parities. All of the included studies were assessed for quality. RESULTS Forty-nine articles were included. Data on epidemiology were reported in 31, HRQoL burden in 16, and economic burden in 7 studies. Diagnosis of BED was made using 4th Edition of The Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) criteria in 46 studies. Lifetime prevalence of BED was 1.1-1.9% in the general population (DSM-IV). BED was associated with significant impairment in aspects of HRQoL relating to both physical and mental health; the Short Form 36 Physical and Mental Component Summary mean scores varied between 31.1 to 47.3 and 32.0 to 49.8, respectively. Compared to individuals without eating disorder, BED was related to increased healthcare utilization and costs. Annual direct healthcare costs per BED patient ranged between $2,372 and $3,731. CONCLUSIONS BED is a serious eating disorder that impairs HRQoL and is related to increased healthcare utilization and healthcare costs. The limited literature warrants further research, especially to better understand the long-term HRQoL and economic burden of BED.

Exploring the concept of eating dyscontrol in severely obese patients candidate to bariatric surgery. Clin Obes 2015; 5:22-30. [PMID: 25611584 DOI: 10.1111/cob.12080] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2014] [Revised: 08/28/2014] [Accepted: 09/08/2014] [Indexed: 11/29/2022]
Abstract
Eating dyscontrol constitutes a potential negative predictor for the outcome of treatment strategies for obese patients. The aim of this study was to examine the qualitative characteristics of eating dyscontrol in obese patients who engage in binge eating (BE) compared with those who do not (NBE), and to analyse the relationship between eating dyscontrol and axis-I, axis-II, spectrum psychopathology using instruments that explore mood, panic-agoraphobic, social-phobic, obsessive-compulsive and eating disorders spectrum psychopathology (SCI-MOODS-SR, SCI-PAS-SR, SCI-SHY-SR, SCI-OBS-SR, SCI-ABS-SR). This was a cross-sectional study involving a clinical sample of adult obese patients with severe obesity (average body mass index = 45 ± 8 kg m(-2) ) and candidate to bariatric surgery who were recruited between November 2001 and November 2010 at the Obesity Center of the Endocrinology Unit, University Hospital of Pisa. All participants completed a face-to-face interview, including a diagnostic assessment of axes-I and II mental disorders (using the Structured Clinical Interview for Manual of Mental Disorders, fourth edition [SCID]-I and SCID-II) and filled out self-report spectrum instruments. Among obese patients not affected by BE, eating dyscontrol was highly represented. Indeed, 39.7% (N = 177) of subjects endorsed six or more items of the Anorexia-Bulimia Spectrum Self-Report, lifetime version domain exploring this behaviour. The cumulative probability of having axis-I, axis-II and a spectrum condition disorder increased significantly with the number of eating dyscontrol items endorsed. In both BE and NBE obese subjects, eating dyscontrol may represent an independent dimension strongly related to the spectrum psychopathology and axes I/II disorders. A systematic screening for eating dyscontrol symptoms by means of self-report spectrum instruments may be valuable to assign specific treatment strategies.

Psychopathological characteristics of patients seeking for bariatric surgery, either affected or not by binge eating disorder following the criteria of the DSM IV TR and of the DSM 5. Eat Behav 2015; 16:1-4. [PMID: 25464057 DOI: 10.1016/j.eatbeh.2014.10.004] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/02/2014] [Revised: 08/02/2014] [Accepted: 10/24/2014] [Indexed: 11/24/2022]
Abstract
UNLABELLED We evaluate whether there are any significant differences in psychopathology between severe obese patients affected by Binge Eating Disorder diagnosed following both the DSM IV TR and the DSM5 criteria, and severe obese patients not having an eating disorder. METHOD 118 severe obese patients seeking treatment at a center for bariatric surgery in northern Italy were asked to take part in the current study for a period of six months. Average participant age was 44.27 years, SD 12.42. Age ranged from 18 to 67 years. Average patient BMI was 45.03, SD 7.11, ranging from 32.14 to 66.16 kg/m(2). Seventy seven of the patients (65.3%) were females and 41 (34.7%) were males. BED diagnosis was determined following the diagnostic criteria of both the DSM IV TR and the DSM 5. The presence of other eating disorders was excluded through a clinical screening using the Eating Disorder Inventory (EDI). Patient eating habits and the presence of emotional eating were appraised using the Three-Factor Eating Questionnaire. Levels of depression and anxiety were evaluated using the Beck Depression Inventory and the State Trait Anxiety Inventory. RESULTS 57 out of 118 patients were found to be affected by BED following the DSM 5 criteria; among them 24 followed those of the DSM IV TR. BED patients scored higher on four subscales of the Eating Disorders Inventory: Drive for thinness (DT), Bulimia (B), Body dissatisfaction (BD) and Interoceptive awareness (IA) on the STAI and on the Disinhibition and Hunger subscales of the TFEQ. DISCUSSION The results confirm the presence of high levels of psychopathology among patients diagnosed with BED, even if they have been diagnosed following the criteria of the DSM 5. There is a great overlap in psychopathology between BED patients diagnosed following the DSM IV TR and the DSM 5 criteria.

Abstract
Symptoms of disordered eating are common among patients seeking bariatric surgery, and assessment of eating pathology is typical in pre-surgical evaluations. A systematic review was conducted to evaluate the definitions, diagnostic criteria and measures used to assess disordered eating in adults seeking bariatric surgery. The review identified 147 articles featuring 34 questionnaires and 45 interviews used in pre-surgical assessments. The Questionnaire on Eating and Weight Patterns Revised and the Structured Clinical Interview for DSM were the most frequently used questionnaire and interview respectively. Variations to pre-surgical diagnostic criteria included changes to the frequency and duration criteria for binge eating, and inconsistent use of disordered eating definitions (e.g., grazing). Results demonstrate a paucity of measures designed specifically for an obese sample, and only 24% of questionnaires and 4% of interviews used had any reported psychometric evaluation in bariatric surgery candidates. The psychometric data available suggest that interview assessments are critical for accurately identifying binge episodes and other diagnostic information, while self-report questionnaires may be valuable for providing additional information of clinical utility (e.g., severity of eating, shape and weight-related concerns). Findings highlight the need for consensus on disordered eating diagnostic criteria and psychometric evaluation of measures to determine whether existing measures provide a valid assessment of disordered eating in this population. Consistent diagnosis and the use of validated measures will facilitate accurate identification of disordered eating in the pre-surgical population to enable assessment of suitability for surgery and appropriate targeting of treatment for disordered eating to optimise treatment success.

Abstract
OBJECTIVE To report the case of a morbidly obese 49-year-old woman with nonspecific interstitial pneumonia who underwent bariatric surgery. Because of inadequate weight loss after sleeve gastrectomy, duodenal switch as component of a stepwise treatment was performed and led to unexplained progressive weight loss and malnutrition. METHOD Case report. RESULTS After duodenal switch surgery, the patient presented with late postsurgical symptoms of malabsorption. Postsurgical psychological evaluation revealed a persistent binge eating disorder. Along with exocrine pancreatic insufficiency, binge eating had led to progressive weight loss of ≈100 kg from a body mass index of 50.3 kg/m(2) presurgery to 17.3 kg/m(2) postsurgery. DISCUSSION Recent research has focused on eating patterns after bariatric surgery and the risks of exacerbating eating disorders after surgery. This case study illustrates the need for auxiliary prepsychotherapeutic and postpsychotherapeutic evaluation and subsequent support for patients with eating disorders preparing for bariatric surgery.

Abstract
OBJECTIVE This article addresses the state of the art concerning the treatment of binge eating disorder (BED). Pharmacological and psychotherapeutic strategies, together with issues concerning the involvement in bariatric surgery are considered. METHOD A Medline enquiry of published articles was performed using the following keywords: BED, pharmacological treatment, duloxetine, venlafaxine, SSRI, psychotherapy, bariatric surgery; reviews and single-case studies were also analyzed. RESULTS Psychological interventions that have shown efficacy in the treatment of Bulimia Nervosa have also been tested in BED with positive results, in particular modified cognitive behavioral therapy, interpersonal therapy and dialectical behavior therapy. In addition pharmacotherapy with SSRIs is successful in transiently reducing binge-eating and body weight; the SNRI duloxetine is effective for reducing binge eating, and global severity of illness with a controversial effect on body weight; both topiramate and sibutramine seem promising, but their use is restricted due to labeling and side effect limitations, respectively. Finally, adequate psychological/pharmacological support can help BED patients obtain positive outcomes from bariatric surgery. CONCLUSION Studies on BED treatment are burdened by several limitations as selection biases (e.g. mostly women and overweight), small samples, high drop-out rates and placebo response.

Abstract
OBJECTIVE To study health-related quality of life (HRQoL) in obese presurgery patients with binge eating disorder (BED) and with subdiagnostic binge eating disorder (SBED) compared to patients without eating disorders or SBED. METHOD Participants were patients referred to St. Olavs University Hospital, Norway, for bariatric surgery. Eating Disorders in Obesity (EDO) questionnaire was used to diagnose BED and SBED. Short-Form Health Survey (SF-12) assessed health-related quality of life. Questionnaires were returned by 160 of 209 patients. The present study sample consisted of 143 patients (103 women and 40 men) as 17 patients did not complete the SF-12. RESULTS Patients with BED and patients with SBED both had significantly lower mental HRQoL, but not physical HRQoL, compared to patients without eating disorders. DISCUSSION The findings indicate that obese presurgery patients with BED, and also SBED, may have special treatment needs in regard to their mental health.
