Abstract
INTRODUCTION Multiple factors are related to lower weight loss after bariatric surgery. This review and meta-analysis evaluates the influence of several mental and behavioral factors on weight loss. METHOD Six electronic databases were searched. Percentage excess weight loss (%EWL) was calculated for all moderator and non-moderator groups of the variables: symptoms of depression, anxiety and binge eating, compliance, physical activity, quality of life, and body image. All moderators, surgery types, and follow-up moments were analyzed separately. RESULTS In total, 75 articles were included in the review; 12 meta-analyses were conducted. Higher postoperative compliance to follow-up was associated with 6.86%-13.68% higher EWL. Preoperative binge eating was related to more weight loss at 24- and 36-month follow-up (7.97% and 11.79%EWL, respectively). Patients with postoperative binge eating symptoms had an 11.92% lower EWL. Patients with preoperative depressive symptoms lost equal weight compared to patients without symptoms. CONCLUSION Despite the high heterogeneity between studies, a trend emerges suggesting that the presence of postoperative binge eating symptoms and lower postoperative compliance may be associated with less weight loss after bariatric-metabolic surgery. Additionally, preoperative depressive symptoms and binge eating do not seem to significantly impact weight loss.

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.

Abstract
Several studies in clinical and non-clinical populations indicate differences between rationally and empirically derived subscales for the Eating Disorder Examination Questionnaire (EDE-Q), including samples of patients seeking bariatric surgery. This study aimed to use exploratory structural equation modelling (ESEM) to estimate the factor structure of the EDE-Q and assess for the additive value of alternative measurement of eating disorder symptoms. Adolescents and adults completed the EDE-Q and a psychiatric evaluation prior to bariatric surgery. Data from 330 participants were analysed using the original four-factor and modified three-factor structure of the EDE-Q using both confirmatory factor analysis (CFA) and exploratory structural equation modelling (ESEM). Age, ethnicity, and body mass index were examined as covariates in the best fitting model, and model subscales used to generate a predictive model of clinician screened DSM-5 eating disorder diagnoses for criterion validity. A CFA of the four-factor EDE-Q provided poor model fit for a pre-surgical bariatric population, but the three-factor EDE-Q and an ESEM of the four-factor EDE-Q provided excellent model fit. The Eating Concern subscale of the four-factor ESEM model significantly predicted eating disorder diagnosis and was positively correlated with age. Our results suggest the ESEM derived factors of the EDE-Q offered some improvements to the original empirically derived factor structure, as subscale scores based on the original items and cross-loading items yielded an adequate prediction of clinician diagnoses.

Abstract
AIMS Depression after bariatric surgery can lead to suboptimal health outcomes. However, it is unclear how depressive symptoms evolve over the 24 months after surgery. We determined the extent depressive symptoms changed up to 24 months after bariatric surgery and how this was impacted by measurement tool and surgical procedure. METHODS We conducted a systematic review and meta-analysis, searching five databases from database inception to June 2021 for studies that prospectively measured depressive symptoms before and up to 24 months after bariatric surgery. Change scores were converted to Hedge's g, and analyses were performed using mixed-effects models. Subgroup analyses examined differences across time of follow-up, measurement tool, and surgical procedure. FINDINGS Forty-six studies met inclusion criteria (32,342 patients). Meta-analysis indicated a postsurgical reduction in depressive symptom scores that were significant (large effect, g = 0.804; 95% CI: 0.73-0.88, I2 = 95.7%). Subgroup analyses found that symptom reductions did not differ between the timing of follow-up periods, measurement tool, and surgical procedure. CONCLUSIONS Depressive symptom scores reduced substantially following surgery; comparable decreases occurred 6 through 24 months after surgery. These findings can help inform practitioners of the typical evolution of depressive symptoms following surgery and where deviations from this may require additional intervention.

Clin Obes 2021; 11:e12458. [PMID: 34053188 PMCID: PMC8365652 DOI: 10.1111/cob.12458] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/09/2021] [Revised: 03/31/2021] [Accepted: 04/11/2021] [Indexed: 11/30/2022]
Abstract
There has been little agreement on the predictive value of emotional eating on weight loss outcomes after bariatric surgery. The aim of this study was to examine the predictive value of preoperative emotional eating, in response to clearly labelled emotions and diffuse emotions, on excess weight loss (EWL) and total weight loss (TWL) 2 years after Roux-en-Y gastric bypass (RYGB). All participants included in this retrospective cohort study were screened for RYGB surgery by a multidisciplinary team. The level of emotional eating was derived from the Dutch Eating Behaviour Questionnaire (DEBQ); the level of psychological variables from the Symptom Checklist-90. Participants were clustered, based on their DEBQ score, in high and low emotional eaters. Multiple linear regression analyses were performed to examine the association between preoperative emotional eating and EWL, and TWL. There were no significant differences in EWL of the 172 included participants, defined as either high or low emotional eaters (EWL 82.7% ±18.2 versus 82.4% ±21.3, respectively). Based on the regression analysis, emotional eating was not significantly associated with EWL, nor with TWL. When corrected for psychological, demographic and biological variables, preoperative emotional eating in response to diffuse emotions negatively affected EWL (β = -0.16, P = 0.048), although this was not applicable for TWL. Preoperative emotional eating does not seem to influence EWL, nor TWL 2 years after RYGB. Since this study faced multiple limitations, further investigation is required regarding the predictive value of emotional eating.

Psychological Outcomes and Predictors of Weight Loss in Adolescents With Severe Obesity Following a Reversible Endoscopic Bariatric Procedure. Front Pediatr 2021; 9:688287.

Abstract
Introduction: Adolescent and children obesity is a growing concern worldwide. Bariatric surgery is used as an effective treatment for adolescents with obesity and provides physical and mental health benefits. Application of alternative, minimally invasive, safe, and reversible endoscopic procedures, such as the Duodenojejunal bypass liner (DJBL), has been recently suggested as an effective treatment for adolescents with obesity. We explored specific psychological outcomes of adolescents with obesity during a year of follow-up after undergoing a reversible endoscopic bariatric procedure, and a year after removal. We were also interested in identifying psychological factors that could predict successful weight loss after the procedure. Methods: Nineteen adolescent with severe obesity undergoing DJBL procedure were psychologically assessed in an open-label, prospective clinical trial (NTC0218393), at the implantation of device and at the removal of device after 12 months. Control group of 26 adolescents with severe obesity were recruited from the same outpatient clinic undergoing only conservative treatment. In addition, adolescents from the intervention group were followed for 12 months after the removal of the device. The Youth Self Report (YSR) was used to assess adolescents' emotional and behavioural problems; The Multidimensional Body-Self Relations Questionnaire (MBSRQ) to assess body image and The Eating Disorder Examination Questionnaire (EDE-Q) to assess attitudes and behaviours related to eating disorder. Results: Significant improvements in somatic complain (F = 12.478, p = 0.001), emotional and behavioural problems (F = 7.169, p = 0.011) and food restraining (F = 9.605, p = 0.004) were found in the intervention group at device removal compared to the control group. Moreover, at the time of device removal compared to baseline, improvements in several psychological outcomes were found (F = 32.178 p = 0.000 for emotional and behavioural problems). Adolescents also became more satisfied with their appearance (F = 6.789, p = 0.019). Majority of observed changes remained stable at the next follow up a year after the device removal. Significant predictors of successful weight loss at device removal were fewer overeating episodes (B = 0.147, p = 0.022) and lower body satisfaction (B = 0.932, p = 0.013). Discussion: Following a reversible bariatric procedure, improvements of psychological (emotional and behavioural) factors were found in adolescents with severe obesity. Psychological predictors of successful weight loss were identified, showing the greatest importance of eating behaviour and body satisfaction in successful weight loss.

Abstract
PURPOSE The aim of this study was to assess depressive symptoms, self-esteem, and eating psychopathology in bariatric surgery patients at the preoperative period (t0) and at the 6-month (t1) and 12-month (t2) follow-ups after laparoscopic sleeve gastrectomy (LSG). A second aim was to investigate associations between these variables and weight loss. METHOD The study participants were 48 bariatric surgery candidates and 50 non-obese controls. Both groups underwent assessment with the Sociodemographic Data Form, Hamilton Depression Rating Scale (HDRS), Eating Disorder Examination Questionnaire (EDE-Q), and Rosenberg Self-esteem Scale (RSES). These assessments were repeated for the patient group at t1 and t2. RESULTS The HDRS, RSES, and EDE-Q scores were higher in the patients before LSG (t0) than in the control group. A significant progressive improvement was identified in the patient HDRS and RSES scores as well as EDE-Q weight and shape subscale scores at t1 and t2. However, the patient EDE-Q total and dietary restraint scores improved at t1 then stabilized. The patient EDE-Q eating concern subscale improved at t1, but then worsened. The patient HDRS scores at t2 were similar to the control group, but the EDE-Q and RSES scores were still higher than the control scores at t2. Regression analyses revealed no association between the preoperative scores and percent changes in postoperative scores for any scale and patient weight loss at t2. CONCLUSION Depressive symptoms, self-esteem, and eating psychopathology showed an improving trend in patients after LSG. However, some aspects of eating psychopathology worsened despite an initial improvement. LEVEL OF EVIDENCE III, prospective cohort and case-control study.

Abstract
PURPOSE After bariatric surgery (BS) a significant minority of patients do not reach successful weight loss or tend to regain weight. In recent years, interest for the psychological factors that predict post-surgical weight loss has increased with the objective of developing interventions aimed to ameliorate post-surgical outcomes. In the present study, predictive models of successful or poor weight loss 12 months after BS were investigated considering pre-surgery level of psychopathological symptoms, dysfunctional eating behaviors and trait impulsivity at baseline (pre-surgery). METHODS Sixty-nine patients with morbid obesity canditates for laparoscopic sleeve gastrectomy were assessed regarding metabolic and psychological dimensions. Successful post-surgery weight loss was defined as losing at least 50% of excess body weight (%EWL). RESULTS Logistic models adjusted for patient sex, age and presence of metabolic diseases showed that the baseline presence of intense psychopathological symptoms and low attentional impulsivity predict poor %EWL (< 50%), as assessed 12-month post-surgery. CONCLUSIONS The present findings suggest that intensity of general psychopathology and impulsivity, among other psychological factors, might affect post-surgery %EWL. Conducting adequate psychological assessment at baseline of patients candidates for BS seems to be crucial to orient specific therapeutic interventions.

Abstract
BACKGROUND Several studies have investigated if bariatric surgery candidates with binge eating disorder (BED) are at risk for suboptimal postoperative weight loss. The aim of this systematic review with meta-analysis was to evaluate the association between binge eating diagnosed preoperatively and weight loss after bariatric surgery. METHODS MEDLINE, EMBASE, CENTRAL, LILACS, and other specialized databases were searched on August 2020. Clinical trials and observational studies including individuals who had undergone any type of bariatric surgical treatment with preoperative evaluation of BED and at least one postoperative measure of weight were initially selected. Four reviewers independently screened for eligibility. The mean difference was calculated using the random-effects model. RESULTS Nineteen studies, comprising 3223 participants (80.25% women; median age 41 years), met the inclusion criteria for meta-analysis. At 6 months postoperative, the percentage of total weight loss (%TWL) was not significantly different between BED and non-BED groups [6 studies, 914 participants: - 0.75% (95% CI, - 2.79 to 1.29; I2 = 0%)], even when analyzing only those three studies that included gold standard assessment tools. No significant differences were found at 12, 24, 36, or 60 months. CONCLUSIONS Pre-bariatric BED seems to have little or no influence on weight loss after surgery. However, many questions remain unanswered because of the use of different measures across studies. The heterogeneity among studies emphasizes the importance of investigators using the same assessment measures.

Abstract
Obesity is a leading global epidemic. Bariatric surgery is the only treatment demonstrating substantial long-term weight loss and medical benefits. However, there is limited research on the psychological outcomes following surgery. Therefore, the primary aim of this study was to systematically review depression, anxiety, and binge eating outcomes at different time points following bariatric surgery and identify whether bariatric surgery significantly reduces psychological symptoms over time. These outcomes were also examined among endoscopic bariatric procedures as a secondary aim. Forty-eight studies met inclusion criteria. Findings suggested that most patients experience a short-term reduction in anxiety and depression symptoms from pre-surgery. Over time, however, these symptoms increase and may even return to pre-surgery levels. Furthermore, while binge eating was uncommon after surgery, other disordered eating patterns may emerge. Binge eating may also restart over time as the stomach enlarges again. Overall, the complex psychological difficulties faced by individuals with obesity continue after surgery and may contribute to longer-term weight recidivism. More comprehensive and standardised psychological assessment procedures, including clinical interviews and longer-term follow-up, may provide insight into the psychological mechanisms maintaining weight management issues, and may serve as a starting point for improving the long-term success of patients with obesity.

OBJECTIVE The current study investigates the hypothesis that the effect of low self-esteem on binge eating in bariatric candidates was mediated by both difficulties in the perception of bodily signals and impulse regulation after accounting for gender, age, and body mass index. METHOD 59 preoperative patients (both male and female) were screened by means of self-report measures of self-esteem, interoceptive deficits, impulse dysregulation, and severity of binge eating. Results: Results indicated that all direct effects were significant, except for the self-esteem on impulse dysregulation and the interoceptive deficits on binge eating. Self-esteem had a significant indirect effect on impulse dysregulation mediated by interoceptive deficits. Impulse dysregulation, in turn, mediates the effect of interoceptive deficits on binge eating. Moreover, the path starting from self-esteem, going first to interoceptive deficits, then going via impulse regulation difficulties to binge eating was significant. RESULTS AND CONCLUSIONS A potential underlying mechanism through which self-esteem is linked to binge eating has been suggested. Obese individuals who perceived themselves as inadequate may carry a stronger burden by the confusion and mistrust related to bodily functioning and, consequently, may act more impulsively, through binge eating.

Abstract
BACKGROUND Few studies have examined weight loss sustainability after sleeve gastrectomy (SG). The purpose of this study was to determine long-term outcome after SG and gastric bypass (GBP) and learn whether preoperative weight loss and binge eating behavior can be used to predict outcome. MATERIALS AND METHODS Together, 257 patients (64 % women) were operated, 163 by GBP and 94 by SG. Binge eating was assessed by binge eating scale (BES) and preoperative weight loss was advised to all, including very low-calorie diet for 5 weeks. Postoperative visits took place at 1 and 2 years, and long-term outcome was at median 5 years (range 2.29-6.85). Multivariate linear regression analysis was used to predict outcome at 2-year and long-term control. RESULTS Median age was 48 years, weight 141.1 kg, and BMI 48.2 kg/m(2). Preoperative weight loss was median 4.9 % before GBP and 3.8 % before SG, P = 0.04. Total weight loss at year one was 24.1 % in GBP and 23.7 % in SG (P = 0.40), at year two 24.4 and 23.4 % (P = 0.26), and at long-term control 23.0 and 20.2 % (P = 0.006), respectively. Weight was analyzed in 93, 88, and 89 % of those alive, respectively. BES did not predict weight outcome, but larger preoperative weight loss predicted less postoperative weight loss at 2 years. CONCLUSION On long term, weight loss was better maintained after GBP compared with SG. Binge eating behavior was not a significant predictor, but larger preoperative weight loss predicted less postoperative weight loss for the next 2 years.

Abstract
OBJECTIVE The objective of this study was to investigate the effects of adherence to postoperative recommended psychiatric follow-up on weight loss in morbid obesity patients with psychiatric disorders 1 year after gastric bypass. METHODS Three hundred eighteen morbidly obese patients were retrospectively reviewed. They were divided into four groups according to preoperative psychiatric evaluations and adherence to psychiatric follow-up 1 year after their bypass surgery. The first group included patients who did not meet the referral criteria (NMRC). The second group consisted of patients who did not meet the psychiatric diagnostic criteria (NMDC). The third group was patients who met criteria for a psychiatric disorder and were nonadherent (NA) to psychiatric follow-up. The fourth group consisted of patients who met criteria for a psychiatric disorder and were adherent (A) to psychiatric follow-up. RESULTS The A group exhibited higher % change in BMI than the NA and NMRC groups at 1 year after bypass surgery. Regression analyses to examine the effects of the grouping variable on % change in BMI were performed by controlling the effects of age, gender, educational level, and preoperative BMI. The regression coefficient for the grouping variable was 0.175 (p = .003) at the 6-month and 0.133 (p = .027) at the 1-year % change in BMI. CONCLUSION Our preliminary data suggest that adherence to postoperative psychiatric follow-up is associated with greater postoperative weight loss. However, evidence from studies with a longer follow-up is required to justify this therapeutic approach.

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 (BED), now recognized as a distinct eating disorder in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, is the most prevalent eating disorder. Although nearly half of individuals with BED are obese, BED also occurs in nonobese individuals. Despite the relatively high percentage of weight loss treatment-seeking individuals meeting BED criteria, primary care physicians may not be familiar with or have ever diagnosed BED. Many providers may also have difficulty distinguishing BED as a contributory factor in obesity. This review differentiates BED from other causes of obesity by describing how obese individuals with BED differ from obese individuals without BED and from nonobese individuals with BED in areas including psychopathology, behavior, genetics, physiology, quality of life and productivity. The ways in which health-care providers can identify individuals who may have BED are also highlighted so the proper course of treatment is pursued. Overall, obese individuals with BED demonstrate a number of key characteristics that differentiate them from obese individuals without eating disorders, including increased impulsivity in response to food stimuli with loss of control over eating, resulting in the consumption of more calories. They also experience significant guilt and other negative emotions following a meal. In addition, individuals with BED patients have more psychiatric comorbidity, display more psychopathology, exhibit longer binge durations, consume more meals as snacks during the day and have less dietary restraint compared with individuals with BED who are not obese. However, the differences between individuals with BED who are obese versus not obese are not as prominent. Taken together, the evidence appears to support the conclusion that BED is a unique and treatable neurobehavioral disorder associated with distinct behavioral and psychological profiles and distinct medical and functional outcomes, and that it is not merely a subtype of obesity.

Abstract
Disordered eating is elevated in bariatric surgery patients and is a risk factor for poor surgical outcomes. A systematic review evaluated the definitions and measurement methods used to identify and assess disordered eating in patients following bariatric surgery. One hundred articles were identified featuring 35 questionnaires and 23 interviews. There were numerous variations to diagnostic criteria and amendments to measures to account for the post-surgical eating context. Only 20% of questionnaires and 4% of interviews had reported psychometric evaluation in post-surgery samples. Results highlight the need for a consistent definition of disordered eating and for current assessment measures to be (a) adapted to account for the altered gastrointestinal system in patients following surgery and (b) psychometrically evaluated in bariatric surgery patients.

Abstract
This study aims to review the obesity literature in order to assess the impact of bariatric surgery on quality of life and the between-study variation by examining the standardized mean magnitude of effect in change in the levels of quality of life. The following databases EMBASE, PubMed, PsycINFO, CINAHL, the Cochrane Library and Web of Science were systematically searched for studies examining change in quality of life in adults receiving bariatric surgery for obesity. Seventy-two studies were included with a total of 9,433 participants treated for obesity with bariatric surgery. The average impact of bariatric surgery on quality of life corresponded to an effect size of 0.88 (95% CI: 0.80-0.96), indicating that bariatric surgery has a significant positive influence on quality of life in general. The impact varied considerably across studies with bariatric surgery showing a significantly greater positive influence on physical quality of life compared to mental quality of life. Bariatric surgery is effective in improving quality of life, especially when looking at physical well-being. Greater focus on the psychological well-being of the person undergoing surgery for obesity may lead to a better post-surgery prognosis for more people.

Abstract
BACKGROUND Bariatric surgery has gained increasing relevance due to the dramatic rise in morbid obesity prevalence. A sound body of scientific literature demonstrates positive long-term outcome of bariatric surgery in decreasing mental and physical health morbidity. Still, there is a need for a manageable presurgical screening to assess major mental disorders. The aim of this study was to assess the frequency of common psychiatric syndromes in bariatric surgery candidates using a computerized version of the Patient Health Questionnaire (PHQ). METHODS In a prospective cohort study from August 2009 to July 2011 morbidly obese individuals seeking bariatric treatment were evaluated for mental health disorders using the PHQ (computerized German version). RESULTS A total of 159 patients were included in this study. The median age of participants was 42 years, the median BMI was 49 kg/m(2). The PHQ revealed a prevalence of 84 % for mental health disorders, 50 % of the participants had three or more mental health disorders. A high somatic symptom burden (46 %), depressive syndromes (62 %) and anxiety disorders (29 %) were the most frequent psychiatric syndromes. The median number of psychiatric syndromes was 3 for women and 1 for men (p = 0.007). No correlation between BMI and a single syndrome or the sum of syndromes was observed. CONCLUSION 84 % of the patients seeking bariatric treatment were screened positive for at least one mental health disorder. The computerized PHQ with automated reporting appears to be a useful instrument for presurgical assessment of bariatric patients in routine medical settings.

Abstract
BACKGROUND Identifying severely obese patients who will succeed after bariatric surgery remains challenging. Although numerous studies have attempted to identify preoperative patient characteristics associated with weight loss, the roles of many dietary and psychological characteristics are unclear. The purpose of this study was to examine preoperative dietary and psychological predictors of successful weight loss after bariatric surgery. MATERIALS AND METHODS This retrospective cohort study included all patients who underwent laparoscopic Roux-en-Y gastric bypass from September 2011-June 2013 at a single institution (n = 124). Patient demographics, comorbidities, dietary and psychological factors, and weight loss outcomes were extracted from the electronic medical record. Bivariate associations between these factors and successful weight loss (≥50% excess body weight) were examined. Factors significant at P ≤ 0.1 were included in a multivariate logistic regression model. RESULTS On bivariate analysis, absence of either type 2 diabetes or hypertension, preoperative weight <270 lbs, no intentional past weight loss >50 lbs, no previous purging or family history of obesity, and no soda consumption preoperatively were associated with successful weight loss (P < 0.1). On multivariate analysis, successful weight loss was inversely associated with the presence of type 2 diabetes (odds ratio [OR], 0.22, 95% confidence interval [CI], 0.06-0.73), maximum intentional past weight loss >50 lbs (OR, 0.12 [95% CI, 0.04-0.43]), and decreasing soda consumption by >50% (OR, 0.27 [95% CI, 0.08-0.99]). CONCLUSIONS Patients with type 2 diabetes mellitus, significant previous weight loss, and poor soda consumption habits are more likely to experience suboptimal weight loss after bariatric surgery. Additional preoperative counseling and close postoperative follow-up is warranted for these patients.

Abstract
BACKGROUND Maladaptive eating behaviors after bariatric surgery are thought to compromise weight outcomes, but little is known about their frequency over time. OBJECTIVE This study investigates the presence of subjective binge eating (SBE), objective binge eating (OBE) and picking and nibbling (P&N) before surgery and at different time periods postoperative, and their association with weight outcomes. METHODS This cross-sectional study assessed a group of patients before surgery (n=61), and three post-operative groups: 1) 90 patients (27 with laparoscopic adjustable gastric band (LAGB) and 63 with Laparoscopic Roux-en-Y Gastric Bypass (LRYGB)) assessed during their 6month follow-up medical appointment; 2) 96 patients (34 LAGB and 62 LRYGB) assessed during their one year follow-up medical appointment; and 3) 127 patients (62 LAGB and 55 LRYGB) assessed during their second year follow-up medical appointment. Assessment included the Eating Disorders Examination and a set of self-report measures. RESULTS In the first ten months after surgery fewer participants reported maladaptive eating behaviors. No OBEs were reported at 6months. SBE episodes were present in all groups. P&N was the most frequently reported eating behavior. Eating behavior (P&N) was significantly associated with weight regain, and non-behavioral variables were associated with weight loss. CONCLUSIONS This study is cross-sectional study which greatly limits the interpretation of outcomes and no causal association can be made. However, a subgroup of postoperative patients report eating behaviors that are associated with greater weight regain. The early detection of these eating behaviors might be important in the prevention of problematic outcomes after bariatric surgery.

Abstract
BACKGROUND People with eating disorders (ED) often report poor health-related quality of life (HRQoL), which is explicitly correlated to illness' severity and its effects on cognitive performance. We aimed to analyze health-related quality of life (HRQoL) in subgroups of eating disorder (ED) patients by using the brief version of WHOQoL questionnaire (WHOQoL-BREF) before treatment administration. Moreover, in order to compare our findings with other published data, we carried out a comprehensive review of the literature on HRQoL in ED patients. METHODS Our review was carried out by means of an accurate data mining of PsychInfo and Medline databases and other available sources. In our cross-sectional study, eighty female ED patients (26 with bulimia nervosa, 33 with anorexia nervosa, 7 with binge eating disorder and 14 with ED not otherwise specified) completed the WHOQoL-BREF. HRQoL scores were compared among ED subgroups and clinical information (presence of previous contacts, length of illness, psychiatric comorbidity) was considered in the analysis. RESULTS Our review shows that with few exceptions ED patients have a poorer HRQoL than the healthy population of control and sometimes the mental component of HRQoL is the most involved dimension. Moreover, there are no differences in the HRQoL among ED groups, even if AN patients in some studies have a lower HRQoL scores. Furthermore, BED patients have a poorer HRQoL than obese patients who do not have binge episodes. Finally, all treatments were positively correlated with an improvement on general and specific QoL dimensions. In our sample, ED subgroups differed only for Psychological Health HRQoL scores (F = 4.072, df = 3; p = 0.01). No differences were found between inpatients and outpatients, treatment naïve and previously treated patients and patients with or without psychiatric comorbidity. Moreover, HRQoL scores were not correlated to length of illness within each ED subgroup. CONCLUSIONS The analysis of the literature adds some relevant information on HRQoL in ED and may address the future research toward the exploration of specific questions. One of these may be the prominent role of Psychological Health domain in HRQoL, since our study confirms that this component is able to differentiate eating disorders.

Abstract
Although bariatric surgery is the most effective intervention for severe obesity, a significant minority of participants fail to achieve or maintain optimal weight loss at extended follow-up. Accumulating evidence suggests that adherence to prescribed postoperative recommendations, including attendance at follow-up appointments and dietary and physical activity, is related to improved weight loss outcomes. However, adherence to these guidelines presents a significant challenge for many patients, potentially due in part to deficits in cognitive function. In this paper, we briefly examine current literature of adherence on postoperative weight loss outcomes, and review emerging evidence that the cognitive dysfunction present in a subset of obese individuals is related to weight loss outcomes following bariatric procedures. We then extend these findings, positing a role for cognitive function in moderating the relationship between adherence and postoperative outcomes.

Meany G, Conceição E, Mitchell JE. Binge eating, binge eating disorder and loss of control eating: effects on weight outcomes after bariatric surgery. EUROPEAN EATING DISORDERS REVIEW 2014; 22:87-91. [PMID: 24347539 PMCID: PMC4420157 DOI: 10.1002/erv.2273] [Citation(s) in RCA: 196] [Impact Index Per Article: 19.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2013] [Revised: 11/19/2013] [Accepted: 11/20/2013] [Indexed: 11/09/2022]
Abstract
There is increasing evidence that patients who have problems with binge eating (BE) or BE disorder (BED) are quite common among the severely obese, including bariatric surgery candidates. The literature suggests that in many cases such eating behaviours improve after bariatric surgery, although this is not uniformly true. The current paper reviews the data on the development of BE, BED and loss of control (LOC) eating after bariatric surgery and the impact of these problems on long-term weight outcome. A search was made of various databases regarding evidence of BE, BED and LOC eating post-operatively in bariatric surgery patients. The data extracted from the literature suggests that 15 research studies have now examined this question. Fourteen of the available 15 studies suggest that the development of problems with BE, BED or LOC eating post-bariatric surgery is associated with less weight loss and/or more weight regain post-bariatric surgery. These data suggests that it is important to identify individuals at high risk for these problems, to follow them post-operatively, and, if appropriate interventions can be developed if such behaviours occur in order to maximize weight loss outcomes.

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
Psychiatric disorders are not uncommon among severely obese patients who present for bariatric surgery. This paper (1) reviews the results of the published studies using the structured interviews to assess psychopathology in bariatric surgery candidates; (2) compares the prevalence rates of psychiatric disorders across these studies with the data from other population samples; and (3) assesses whether sociodemographic variables appear to affect these prevalence rates. We searched online resources, PubMed, PsychINFO and reference lists of all the relevant articles to provide an overview of evidence so far and highlight some details in the assessment and comparisons of different samples in different countries. The prevalence estimates in the non-treatment obese group did not appear to differ substantially from the general population group in the US or the Italian population samples, although they were relatively higher for the German population. However, the rates of psychopathology in the bariatric surgery candidates were considerably higher than the other two population groups in all the samples. Overall, the most common category of lifetime Axis I disorders in all the studies was affective disorders, with anxiety disorders being the most common category of current Axis I disorders. Certain demographic characteristics are also associated with higher rates of psychopathology, such as, female gender, low socioeconomic status, higher BMI. Overall, methodological and sociodemographic differences make these studies difficult to compare and these differences should be taken into account when interpreting the results.

Abstract
BACKGROUND Improvement of mental health and health-related quality of life (HRQOL) is an important success criterion for bariatric surgery. In general, mental health and HRQOL improve after surgery, but some patients experience negative psychological reactions postoperatively and the influence of pre-surgical psychological factors on mental wellbeing after surgery is unclear. The aim of the current article therefore is to review recent research investigating psychological predictors of mental health and HRQOL outcome. METHODS We searched PubMed, PsycInfo and Web of Science for studies investigating psychological predictors of either mental health or HRQOL after bariatric surgery. Original prospective studies published between 2003 and 2012 with a sample size >30 and a minimum of 1 year follow-up were included. RESULTS Only 10 eligible studies were identified. The findings suggest that preoperative psychological factors including psychiatric symptoms, body image and self-esteem may be important for mental health postoperatively. Predictors of postoperative HRQOL seem to include personality, severe psychiatric disorder at baseline and improvement of depressive symptoms. In addition, psychiatric symptoms that persist after surgery and inappropriate eating behaviour postoperatively are likely to contribute to poor health-related quality of life outcome. CONCLUSION Certain psychological factors appear to be important for mental health and HRQOL after bariatric surgery. However, the literature is extremely sparse and further research is highly needed.

Abstract
BACKGROUND Morbid obesity is the fastest growing BMI group in the U.S. and the prevalence of morbid obesity worldwide has never been higher. Bariatric surgery is the most effective treatment for severe forms of obesity especially with regard to a sustained long-term weight loss. Psychological factors are thought to play an important role for maintaining the surgical weight loss. However, results from prior research examining preoperative psychological predictors of weight loss outcome are inconsistent. The aim of this article was to review more recent literature on psychological predictors of surgical weight loss. METHODS We searched PubMed, PsycInfo and Web of Science, for original prospective studies with a sample size >30 and at least one year follow-up, using a combination of search terms such as 'bariatric surgery', 'morbid obesity', 'psychological predictors', and 'weight loss'. Only studies published after 2003 were included. RESULTS 19 eligible studies were identified. Psychological predictors of surgical weight loss investigated in the reviewed studies include cognitive function, personality, psychiatric disorder, and eating behaviour. CONCLUSION In general, recent research remains inconsistent, but the findings suggest that pre-surgical cognitive function, personality, mental health, composite psychological variables and binge eating may predict post-surgical weight loss to the extent that these factors influence post-operative eating behaviour.

Abstract
Bariatric surgery is increasingly being used to treat severe obesity, but little is known about its impact on patient-reported outcomes (PROs). For PRO data to influence practice, well-designed and reported studies are required. A systematic review identified prospective bariatric surgery studies that used validated PRO measures. Risk of bias in randomized controlled trials (RCTs) was assessed, and papers were examined for reporting of (i) who completed PRO measures; (ii) missing PRO data and (iii) clinical interpretation of PRO data. Studies meeting all criteria were classified as robust. Eighty-six studies were identified. Of the eight RCTs, risk of bias was high in one and unclear in seven. Sixty-eight different PRO measures were identified, with the Short Form (SF)-36 questionnaire most commonly used. Forty-one (48%) studies explicitly stated measures were completed by patients, 63 (73%) documented missing PRO data and 50 (58%) interpreted PRO data clinically. Twenty-six (30%) met all criteria. Although many bariatric surgery studies assess PROs, study design and reporting is often poor, limiting data interpretation and synthesis. Well-designed studies that include agreed PRO measures are needed with reporting to include integration with clinical outcomes to inform practice.

Abstract
BACKGROUND This study assessed the utility of the Binge Eating Scale (BES) as a measure of binge eating disorder (BED) in a bariatric surgery-seeking population by (a) determining the optimal BES cut score for predicting BED, (b) calculating concordance statistics, and (c) determining the predictive value of each BES item. METHODS Four hundred seventy-three patients presented for a psychological evaluation prior to Roux-en-Y gastric bypass surgery. The BES and the SCID semi-structured interview for BED were administered. RESULTS Receiver operating characteristic curve analyses identified an optimal BES cut score of 17, which correctly classified 78% of patients with BED. A cut score of 27 improved this statistic, but significantly increased the number of false negatives, which is undesirable for a screening assessment. Discriminant function analyses revealed that nearly all BES items significantly predicted BED. CONCLUSIONS The BES is a valid screener of BED for patients seeking bariatric surgery; however, false positives can be expected. Administering the BES as part of a comprehensive psychological evaluation can help improve the assessment and treatment of patients presenting for bariatric surgery.

Abstract
OBJECTIVE There is a growing research literature suggesting that there may be elevated risk of suicide following bariatric surgery. Most of the data reported thus far has been cross-sectional and observational, and very little is known about the possible specific causal variables involved. DESIGN AND METHODS The purpose of this report is to review this literature and to review possible risk factors for increased suicidal risk following bariatric surgery, to delineate future research directions. RESULTS First a variety of medical, biological, and genetic factors, including the persistence or recurrence of medical comorbidities after bariatric surgery, the disinhibition and impulsivity secondary to changes in the absorption of alcohol, hypoglycemia, as well as pharmacokinetic changes that may affect the absorption of various medications including antidepressant medications are reviewed. Also reviewed are possible mediating factors involving changes in various peptidergic systems such as GLP-1 and Ghrelin. A number of psychosocial issues that might be involved are discussed, including lack of improvement in quality of life after surgery, continued or recurrent physical mobility restrictions, persistence or recurrence of sexual dysfunction and relationship problems, low self-esteem, and a history of child maltreatment. Inadequate weight loss or weight regain are also discussed. CONCLUSIONS A number of possible contributing factors have been identified. Possible theoretical models involved and directions for research are suggested.

Abstract
Over the past several decades, excessive body weight has become a major health concern. As the obesity epidemic continues to expand, metabolic disorders associated with excess body weight, including type 2 diabetes, dyslipidemia, hypertension, and cardiovascular disease, have exponentially increased. Dysregulation of satiety hormones and factors that regulate long-term energy storage can disrupt normal metabolic functions and lead to excess body fat. While diet and exercise seem to provide a logical means for weight loss, an unhealthy lifestyle coupled to responses initiated by perceived energy deficit impede sustained long term weight loss. Furthermore, because of the additional lack of effective pharmaceutical interventions to treat excess body weight, patients with severe obesity resort to bariatric surgery as an effective alternative for treatment of obesity and resolution of its associated comorbidities. Interestingly, the precise method by which bariatric surgery promotes rapid improvement in systemic metabolism and long-term weight loss remains incompletely understood and may vary between procedures. Multiple mechanisms likely contribute to the improved glucose metabolism seen after bariatric surgery, including caloric restriction, changes in the enteroinsular axis, alterations in the adipoinsular axis, release of nutrient-stimulated hormones from endocrine organs, stimulation from the nervous system, and psychosocial aspects including a dramatic improvement in quality of life. The current review will highlight the potential contribution of these responses to the improvement in systemic energy metabolism elicited by bariatric surgery.

Abstract
BACKGROUND The interaction between motivation to eat, eating behavior traits, and gut peptides after Roux-en-Y gastric bypass (RYGB) surgery is not fully understood. METHODS Appetite and hormone responses to a fixed liquid preload were assessed in 12 obese (body mass index 45 ± 1.9 kg/m(2)) participants immediately before and 3 days, 2 months, and 1 year after RYGB surgery. Subjective appetite and plasma levels of ghrelin, leptin, insulin, and glucagon-like peptide-1 (GLP-1) were measured for a 3-hour postprandial period. Eating behavior traits were also measured using the Three Factor Eating Questionnaire 18 (TFEQR18). RESULTS There was a decrease in TFEQR18 emotional eating (EE) and uncontrolled eating (UE) from presurgery to 1 year postsurgery but no significant change in cognitive restraint (CR). These changes occurred independently of change in weight. In addition, there was a reduction in subjective appetite ratings and alterations in appetite peptides favoring an anorectic response. Presurgery EE was significantly related to fasting and area under the curve (AUC) ghrelin; UE was associated with AUC desire to eat, and there was a significant association between fasting desire to eat and ghrelin (fasting and AUC). One year postsurgery, UE was positively related to fasting insulin, and CR was negatively associated with GLP-1. UE and subjective hunger were positively correlated, while the relationship between desire to eat and ghrelin remained. CONCLUSION The relationships among subjective appetite ratings, eating behavior traits, and appetite peptides in obese patients both before and at 1 year after RYGB surgery may contribute to the reduction in a propensity to overeat (as measured by TFEQR18 factors) and weight loss.

Abstract
BACKGROUND Obesity affects 32% of adults in the USA. Surgery generates substantial weight loss, but 20-30% fails to achieve successful weight loss. Our objective was to identify preoperative psychosocial factors associated with weight loss following bariatric surgery. METHODS We performed a literature search of PubMed® and the Cochrane Database of Reviews of Effectiveness between 1988 and April 2010. Articles were screened for bariatric surgery and weight loss if they included a preoperative predictor of weight loss: body mass index (BMI), preoperative weight loss, eating disorders, or psychiatric disorder/substance abuse. One thousand seven titles were reviewed, 534 articles screened, and 115 included in the review. RESULTS Factors that may be positively associated with weight loss after surgery include mandatory preoperative weight loss (7 of 14 studies with positive association). Factors that may be negatively associated with weight loss include preoperative BMI (37 out of 62 studies with negative association), super-obesity (24 out of 33 studies), and personality disorders (7 out of 14 studies). Meta-analysis revealed a decrease of 10.1% excess weight loss (EWL) for super-obese patients (95% confidence interval (CI) [3.7-16.5%]), though there was significant heterogeneity in the meta-analysis, and an increase of 5.9% EWL for patients with binge eating at 12 months after surgery (95% CI [1.9-9.8%]). CONCLUSIONS Further studies are necessary to investigate whether preoperative factors can predict a clinically meaningful difference in weight loss after bariatric surgery. The identification of predictive factors may improve patient selection and help develop interventions targeting specific needs of patients.

Abstract
OBJECTIVE To study the prevalence of all relevant eating disorders in 157 obese patients waiting for bariatric surgery. Another aim was to explore for possible differences between gender, and those with and without ED. The dependent variables were: socio-demographic characteristics, BMI, obesity onset, and obesity-related somatic diseases. METHODS ED was assessed using the self-report questionnaire, "Eating Disorders in Obesity" (EDO). The patients answered a questionnaire that targeted socio-demographic and health information. RESULTS Subgroups were based on the patients responses to items on the EDO: 1 patient (0.6%) with Bulimia Nervosa (BN), 6 (3.8%) with Eating Disorder Not Otherwise Specified (EDNOS), 21 (13.4%) with Binge Eating Disorder (BED), and 23 (14.6%) with Binge Eating (BE). The patients in the EDNOS group were those who lacked one criterion of the BN diagnosis. The patients in the BE group lacked one criterion of the BED diagnosis. Twenty-eight (17.8%) fulfilled the DSM-IV-TR criteria for ED. When patients with BE were added, 51 patients (32.5%) were identified with ED or sub-threshold ED. In the explorative part of the study, no gender differences in socio-demographic variables, BMI, obesity onset, and obesity-related somatic diseases emerged. With the exception of age, no differences were found in these variables between those with and without ED. CONCLUSION Employing all relevant eating disorders and binge eating symptoms (BE) for this population identified patients with pathological eating behaviors, which are not detected in previous studies measuring only BED and BE.

Abstract
Obesity is a public health epidemic with medical, psychological and economic consequences. It continues to increase globally in prevalence and severity. Despite numerous behaviourally, medically or pharmacologically guided treatments, an effective non-surgical long-term treatment approach has not been identified. Bariatric surgery has surfaced as a viable option for a subset of individuals with medically complicated obesity who have failed non-surgical approaches. Pre-operative evaluation followed by post-operative, longitudinal follow-up by a multidisciplinary team specializing in surgery, medicine, psychiatry/psychology, exercise science and nutrition constitutes recognized and necessary standard of care for these complex patients. More information is needed regarding factors that interfere with successful outcomes and mechanisms of optimal follow-up for bariatric surgery patients to prevent and detect post-operative medical, psychological and social difficulties. We will review these issues with a focus on issues relevant to eating disorders professionals.

Abstract
O objetivo foi fazer uma revisão sistemática dos estudos que avaliam qualidade de vida em pessoas com transtornos alimentares. Foram realizadas buscas bibliográficas em seis bases de dados e buscas manuais em duas revistas, abrangendo o período de janeiro de 1975 até junho de 2008. As estratégias de busca forneceram um total de 29.537 referências. Quarenta e um estudos preencheram os critérios de inclusão desta revisão e 36 foram analisados no presente trabalho. De modo geral, os estudos revelam prejuízos na qualidade de vida de pacientes com transtornos alimentares quando comparados a grupos normais ou outras patologias psiquiátricas. O aspecto mental da qualidade de vida mostra-se mais prejudicado. A avaliação da qualidade de vida em sujeitos com transtorno da compulsão alimentar periódica revela prejuízos nos aspectos físico e mental da qualidade de vida. Há pouca evidência e discussão para indivíduos com bulimia nervosa isoladamente. Em sujeitos com anorexia nervosa, a avaliação requer cautela, já que o aparente menor impacto físico pode ser reflexo da psicopatologia específica deste transtorno e não do funcionamento saudável.

Abstract
OBJECTIVE This study examined the clinical significance of loss of control (LOC) over eating in bariatric surgery patients over 24 months of prospective, multiwave follow-ups. METHOD Three hundred sixty-one gastric bypass surgery patients completed a battery of assessments before surgery and at 6, 12, and 24 months following surgery. In addition to weight loss and LOC over eating, the assessments targeted eating disorder psychopathology, depression levels, and quality of life. The study was conducted between January 2002 and February 2008. RESULTS Prior to surgery, 61% of patients reported general LOC; postsurgery, 31% reported LOC at 6-month follow-up, 36% reported LOC at 12-month follow-up, and 39% reported LOC at 24-month follow-up. Preoperative LOC did not predict postoperative outcomes. In contrast, mixed models analyses revealed that postsurgery LOC was predictive of weight loss outcomes: patients with LOC postsurgery lost significantly less weight at 12-month (34.6% vs 37.2% BMI loss) and 24-month (35.8% vs 39.1% BMI loss) postsurgery follow-ups. Postsurgery LOC also significantly predicted eating disorder psychopathology, depression, and quality of life at 12- and 24-month postsurgery follow-ups. CONCLUSIONS Preoperative LOC does not appear to be a negative prognostic indicator for postsurgical outcomes. Postoperative LOC, however, significantly predicts poorer postsurgical weight loss and psychosocial outcomes at 12 and 24 months following surgery. Since LOC following bariatric surgery significantly predicts attenuated postsurgical improvements, it may signal a need for clinical attention.

Abstract
Obesity is the 'disease of the 21st century' and results in physical and psychosocial co-morbidities as well as poor quality of life (QoL). In contrast to the nonsurgical treatment of obesity, bariatric surgery is treatment of choice for morbid obesity. Since improved QoL and enhanced psychosocial functioning are important goals of bariatric surgery, success following bariatric surgery should not only include weight loss and improvement or cure of co-morbid conditions, but also improvements in eating behavior, psychosocial variables, and QoL. Unfortunately, bariatric surgery does not lead to identical results in every patient. Patients who fail to adjust their eating behavior and lifestyle after bariatric surgery may experience adverse reactions. Compliance and adjustment may be attributed largely to psychological factors, implying that the operation on its own represents only one element in bariatric surgery. Considering the role of psychosocial factors in the outcomes of bariatric surgery and the impact of the operation on the psychological and social situation, mental health professionals should be a part of the process of evaluation and treatment of bariatric surgery patients. In the Netherlands, between 2000 and 2005, bariatric surgery has increased tremendously, and most Dutch hospitals have a multidisciplinary selection process.

Abstract
The process of psychosocial evaluation for weight loss surgery (WLS) is one that goes beyond serving the function of information-gathering (Bauchowitz et al. in Surg Obes Relat Dis 3:554-558, 2007; Friedman et al. in Surg Obes Relat Dis 3:376-382, 2007; Lanyon and Maxwell in Obes Surg 17:321-328, 2007; Sogg and Mori in Obes Surg 14:370-380, 2004; Sogg and Mori in Surg Obes Relat Dis 4:455-463, 2008). This process offers myriad opportunities for delivering significant and powerful interventions that can enhance the patient's success in the WLS process. A discussion of the unique opportunities for psychosocial intervention afforded by the pre-surgical evaluation process is presented, using The Boston Interview for Bariatric Surgery (Sogg and Mori in Surg Obes Relat Dis 4:455-463, 2008) as the organizing framework.

Abstract
BACKGROUND Roux-en-Y gastric bypass patients often undergo preoperative dieting and psychological assessment before surgery. We examined preoperative weight loss, binge eating disorder (BED), and sexual abuse history and the interactions of these predictors to determine whether a cautionary approach to Roux-en-Y gastric bypass is warranted. METHODS Consecutive subjects undergoing Roux-en-Y gastric bypass at our institution from January 1997 to December 2002 were reviewed. The postoperative excess weight loss (EWL) at 1, 3, 6, 12, 18, and 24 months and the perioperative complications were measured. EWL was compared at 12 and 24 months postoperatively in the categories of the presence/absence of preoperative weight loss, BED, and sexual abuse history. The perioperative complications were examined in the preoperative weight change groups. RESULTS Of 154 patients, 121 were included. No significant difference in EWL or perioperative complications was observed between those who lost or gained weight preoperatively. Of the 121 patients, 32% and 17% reported a history of BED and sexual abuse, respectively. No statistically significant difference was observed in the EWL between those with and without BED at 12 and 24 months postoperatively. The EWL in those with and without a sexual abuse history at 12 and 24 months was 57.67% and 66.32% (P <.05) and 64.40% and 70.97% (P = NS). No statistically significant interaction between EWL and sexual abuse*BED/sexual abuse*preoperative weight loss was observed. CONCLUSION Only sexual abuse history at postoperative month 12 had a negative effect on EWL. Otherwise, physicians can expect to see successful EWL in these subjects up to 24 months postoperatively. We recommend that additional investigation be done of those with BED and a sexual abuse history.

Abstract
BACKGROUND Although most bariatric surgery patients undergo a preoperative psychological evaluation, the potential effect of psychiatric disorders on weight loss is not well understood. We sought to document the relationship of preoperative psychiatric disorders to the 6-month outcomes after gastric bypass. METHODS The Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) was used to assess current and lifetime Axis I clinical disorders, as well as Axis II personality disorders, before surgery. We used linear regression models to examine the relationship of psychiatric disorders to postoperative weight-related outcomes. RESULTS The sample (n = 207) was 83.1% female and 92.7% white. The preoperative body mass index (BMI) was 51.4 +/- 9.6 kg/m(2) and age was 45.8 +/- 9.5 years. After adjusting for the initial BMI, gender, race, and age, a lifetime Axis I disorder was associated with a smaller decrease in BMI (t = -3.7, df = 205, P <.001) at 6 months after surgery. The results of separate models for each class of disorder indicated that lifetime mood disorder was associated with a smaller decrease in BMI (t = -3.7, df = 205, P <.001), as was lifetime anxiety disorder (t = -2.6, df = 205, P = 0.009), but substance and eating disorders were not. In this sample, current Axis I clinical disorders and Axis II personality disorders were unrelated to outcomes at 6 months. Similar overall results were found when the percentage of weight loss and excess weight loss were predicted. CONCLUSION The results of our study have shown that patients who have ever had an Axis I clinical disorder, especially mood or anxiety, exhibit poorer weight outcomes 6 months after gastric bypass than those who have never had an Axis I disorder. Additional research with larger samples is needed to replicate these findings and examine more fully the effect of current clinical disorders and personality disorders on weight loss. Nevertheless, our results suggest that patients with current or past disorders might benefit from close monitoring or psychosocial intervention to improve their short-term outcomes. However, a greater duration of follow-up is needed to identify predictors of longer-term weight control.

Abstract
BACKGROUND Gastric restrictive surgery induces a marked change in eating behavior. However, the relationship between preoperative and postoperative eating behavior and weight loss outcome has received limited attention. OBJECTIVE This study assessed a range of eating behaviors before and 1 year after laparoscopic adjustable gastric banding (LAGB) and explored the nature and extent of change in eating patterns, their clinical associates, and impact on weight loss. METHODS AND PROCEDURES A 12-month observational study assessed presurgical and postsurgical binge eating disorder (BED), uncontrolled eating, night eating syndrome (NES), grazing, nutrient intake and eating-related behaviors, and markers of psychological distress. A total of 129 subjects (26 male and 103 female, mean age 45.2 +/- 11.5 and BMI 44.3 +/- 6.8) participated in this study. RESULTS Presurgical BED, uncontrolled eating, and NES occurred in 14%, 31%, and 17.1% of subjects, which reduced after surgery to 3.1%, 22.5%, and 7.8%, respectively (P = 0.05 for all). Grazing was prevalent before (26.3%) and after surgery (38.0%). Preoperative BED most frequently became grazers (P = 0.029). The average percentage weight loss (%WL) was 20.8 +/- 8.5%; range -0.67 to 50.0% and percentage of excess weight loss (%EWL) 50.0 +/- 20.7%; range -1.44 to 106.9% (P < 0.001). Uncontrolled eating and grazing after surgery showed high overlap and were associated with poorer %WL (P = 0.008 and P < 0.001, respectively) and elevated psychological distress. DISCUSSION Consistent with recent studies, uncontrolled eating and grazing were identified as two high-risk eating patterns after surgery. Clearer characterization of favorable and unfavorable postsurgical eating behaviors, reliable methods to assess their presence, and empirically tested postsurgical intervention strategies are required to optimize weight loss outcomes and facilitate psychological well-being in at-risk groups.

Abstract
BACKGROUND In recent years, particular attention has been paid to the effect that eating disturbances and especially binge eating can have on the outcome of surgical treatments for obesity. Endoscopic positioning of the Bioenterics intragastric balloon (BIB) is mainly used in the work-up for surgical treatment of morbid obesity. Available data show that the BIB is a valid tool for reducing weight and co-morbidity, even if only a temporary treatment in morbidly obese patients. We evaluated the results of treatment with the BIB with the patient's tendency to indulge in binge eating. METHODS Between April 2003 and March 2006, 89 patients with morbid obesity (BMI 39-55) were enrolled in the study. Before introducing the BIB and within 3 months after removal, patients underwent a psychiatric evaluation and the following psychodiagnostic tests: SCID (Structured Clinical Interview for DSM IV), ED-SCID (Eating Disorder Module, Structured Clinical Interview) and BSQ (Binge Scale Questionnaire). All those positive for the BED criteria according to the DSM IV, and who had at least one binge eating episode per week, were considered Binge Eaters (BE). RESULTS Of the 89 patients enrolled, 75 were eligible for evaluations (M:F = 12:63), and 27 were positive for binge eating (BE). There were no significant differences in age and preoperative BMI between the BE group and the 48 patients without BE (NBE group). The complication and failure rates with the BIB treatment were significantly higher in the BE group (P<0.01). After treatment with the BIB, both groups showed a significant reduction in BMI (P<0.01), but the NBE-group showed a significantly higher weight (BMI 5.7 +/- 2.5 kg/m2) than the BE-group (BMI 3.3 +/- 2.2 kg/m2) (P=0.03). CONCLUSION The results of treatment with the intragastric balloon appear to be affected by binge eating pattern in morbidly obese patients, even if the presence of this behavior does not prevent a successful reduction in the BMI. Binge eating does not seem to be a contraindication for the adjuvant use of the BIB before a bariatric operation. A limitation of our study is the short period of observation, related to the period of the BIB in the gastric lumen (not more than 6 months). Further studies may show whether the association of psychiatric treatment with the BIB in patients affected by binge eating may enhance the results of the treatment.

Abstract
BACKGROUND Binge-eating disorder (BED) may be associated with unsatisfactory weight loss in obese patients submitted to bariatric procedures. This study aims to investigate whether the presence of binge eating before Roux-en-Y gastric bypass (RYGBP) influences weight outcomes. METHODS In a prospective design, 216 obese patients (37 males, 178 females, BMI=45.9 +/- 6.0 kg/m2) were assessed for the lifetime prevalence of BED and classified at structured interview into 3 subgroups: no binge eating (NBE=43), sub-threshold binge eating (SBE=129), and binge-eating disorder (BED=44). All patients were encouraged to take part in a multidisciplinary program following surgery, and weight loss at follow-up was used as the outcome variable. RESULTS At 1-year follow-up, NBE patients (n=41) showed percent excess BMI loss (%EBL) significantly higher than SBE patients (n=112) (P=0.027), although this effect was not significantly different between NBE and BED patients (n=44). At 2-year follow-up, NBE patients (n=33) showed %EBL higher than SBE (n=64) (P=-0.003) and BED patients (n=34) (P<0.001). Nevertheless, we found no significant weight loss differences between SBE (subclinical) and BED (full criteria) patients at any period of follow-up. Preliminary results at 3-year follow-up suggest that such an effect may be enduring. CONCLUSION The presence of a history of binge eating prior to treatment is associated with poorer weight loss in obese patients submitted to RYGBP. Because BED is highly prevalent in obese patients seeking bariatric surgery, its early recognition and treatment may be of important clinical value.
