Binge Eating, Loss of Control over Eating, Emotional Eating, and Night Eating After Bariatric Surgery: Results from the Toronto Bari-PSYCH Cohort Study

Evaluating Night-Eating Syndrome in bariatric surgery patients: A cross-sectional study

BACKGROUND

Night-Eating Syndrome (NES) is a complex eating disorder that has gained recognition in the context of bariatric surgery. However, its prevalence and associated factors in this specific patient population remain understudied, particularly in the Saudi Arabian context.

METHODS

This cross-sectional study was conducted at King Abdulaziz University Hospital in Jeddah, Saudi Arabia, from June to November 2022. Adult patients who had undergone bariatric surgery with a postoperative follow-up of 6 months were included. NES was assessed using the Night Eating Questionnaire (NEQ).

RESULTS

A total of 154 patients were enrolled in the study, with a mean age of 38.8 ± 11.4 years. The mean BMI before surgery was 44.8 ± 8.2 kg/m2, which reduced to 28.9 ± 5.8 kg/m2 post-surgery. Of these, 52 patients (33.8%) met the criteria for NES based on NEQ scores. The prevalence of NES was significantly higher among female patients, with 35 out of 83 females (42.2%) compared to 17 out of 71 males (23.9%) experiencing NES. While NES was not significantly associated with age, nationality, diet adherence, BMI, or surgery type, chronic diseases-particularly diabetes-emerged as significant risk factors for NES in post-bariatric surgery patients.

CONCLUSION

NES is a prevalent concern among post-bariatric surgery patients, with distinct associations with gender and chronic diseases, particularly diabetes. This study provides valuable insights into NES prevalence and its risk factors in the Saudi Arabian context, highlighting the importance of addressing eating disorders within the framework of bariatric surgery care.

The Association between Grazing and Food Addiction: The Italian Version of the Repetitive Eating Questionnaire (Rep(Eat)-Q) and Its Relationships with Food Addiction Criteria

BACKGROUND

Among the dysfunctional eating behaviors associated with excessive food intake, a construct that is gaining increasing attention is grazing-the constant, continuous, compulsive, and repetitive consumption of small/moderate amounts of food. Furthermore, in some cases, grazing seems to indicate a dependence on food and/or eating. Currently, the Repetitive Eating Questionnaire (Rep(Eat)-Q) appears to be the only questionnaire that comprehensively measures grazing, including its repetitive and compulsive eating component. Therefore, in a sample of individuals with severe obesity, the objective of this study was twofold: (A) to evaluate the psychometric properties of the Italian version of the Rep(Eat)-Q, and (B) to analyze the association between grazing and food addiction (FA).

METHOD

A cross-sectional research design was used. A total of 402 inpatients with severe obesity (BMI > 35) were recruited. Participants underwent a series of questionnaires to investigate structural validity and convergent validity and association with FA criteria.

RESULTS

The factorial structure of the Rep(Eat)-Q is robust and showed fit indexes: CFI = 0.973; RMSEA = 0.074; 90%CI [0.056-0.091]; and SRMR = 0.029. Also, it exhibited good internal consistency and convergent validity. Furthermore, logistic regression analysis highlights a specific association between certain FA criteria and grazing.

CONCLUSIONS

The Rep(Eat)-Q can be considered to be a concise, robust, reliable, and statistically sound tool to assess repetitive eating, specifically grazing. Its strong psychometric properties offer significant advantages for both research and clinical applications. Furthermore, in a sample of individuals with severe obesity, the results suggest that individuals with problematic grazing exhibit a typical behavioral profile of subjects with FA, indicating that FA can manifest through problematic grazing as well.

Cannabis use following bariatric surgery is associated with anxiety and maladaptive eating

BACKGROUND

There are limited data regarding the association of cannabis use with outcomes after bariatric surgery. As such, it is challenging to know how to counsel patients using cannabis.

OBJECTIVES

The purpose of this study was to examine whether postsurgical cannabis use was associated with psychiatric symptoms and maladaptive eating among individuals up to 4 years after bariatric surgery.

SETTING

Single health system.

METHODS

All patients who underwent bariatric surgery over a 4-year period were invited to participate. Participants (N = 765) completed questionnaires online regarding postsurgical cannabis use, psychiatric symptoms, and maladaptive eating.

RESULTS

Any cannabis use after bariatric surgery was associated with increased likelihood of having elevated symptoms of anxiety (odds ratio [OR] = 1.88, P = .003; 37.8% versus 24.4%), increased likelihood of grazing behaviors (OR = 1.77, P = .01; 71.2% versus 58.2%), and higher scores for eating in response to depression (P = .01; 12.13 versus 10.75). Weekly cannabis use was associated with loss of control eating (OR = 1.81, P = .04; 37.2% versus 24.7%), binge eating (OR = 2.16, P = .03; 20.0% versus 10.4%), and night eating behaviors (OR = 2.11, P = .01; 40.0% versus 24.0%). Cannabis use was not associated with depression (P > .05).

CONCLUSIONS

Cannabis use after bariatric surgery was associated with anxiety symptoms and engaging in maladaptive eating behaviors. Frequent cannabis use (i.e., ≥1 per week) was associated with additional types of maladaptive eating. Clinicians involved in presurgical and postsurgical care may want to counsel patients currently using cannabis, especially those who are engaging in frequent use.

Racial Differences in Psychiatric Symptoms, Maladaptive Eating, and Lifestyle Behaviors After Bariatric Surgery

There are several psychological and behavioral factors associated with poorer outcomes following bariatric surgery, yet it is unknown whether and how these factors may differ by race. In this cross-sectional study, individuals who underwent bariatric surgery from 2018 to 2021 and up to 4 years post-surgery were invited to complete an online survey. Psychiatric symptoms, maladaptive eating patterns, self-monitoring behaviors, and exercise frequency were examined. Participants (N = 733) were 87% women, 63% White, with a mean age of 44 years. Analyses of covariance demonstrated that White individuals endorsed greater anxiety symptoms (p =.01) and emotional eating due to depression (p = .01), whereas Black individuals endorsed greater depression severity (p = .02). Logistic regression analyses demonstrated that White individuals were more likely to experience loss of control eating (OR= 1.7, p = .002), grazing (OR= 2.53, p <.001), and regular self-weighing (OR= 1.41, p <.001) than Black individuals, and were less likely to skip meals (OR= .61, p = .04), or partake in nighttime eating (OR= .40, p <.001). There were no racial differences in binge eating, emotional eating due to anxiety or frustration, use of a food diary, or exercise. Thus, depressive symptoms, skipping meals, and nighttime eating may be important, modifiable intervention targets to optimize the benefits of bariatric surgery and promote equitable outcomes.

Psychopathological profile before and after bariatric surgery

Presurgical psychopathological assessment usually focuses on detecting severe mental disorders. However, mild intensity psychopathology and eating behaviour pattern may also influence postsurgical outcomes. The aim was to identify psychopathology and eating behaviour pattern in candidates prepared for bariatric surgery compared to a normative population before and after surgery. A cohort of 32 patients seeking bariatric surgery in a university hospital between March 2016 and March 2017 were evaluated with Personality Assessment Inventory (PAI), 36-item EDE-Q and BES before and after surgery. Thirty-two patients before and 26 one year after surgery were included. The PAI presurgical psychometric profile suggested a mild mixed adjustment disorder focused on somatic complaints. After surgery, patients improved in somatic complaints (p < 0.001), and depression (p = 0.04). Related eating disorders were more common than those of the normative group and improved significantly after surgery in scores for compulsive intake (BES p < 0.001) and overall key behaviours of eating disorders and related cognitive symptoms (EDE-Q/G p < 0.001). In our cohort ready for bariatric surgery a mild psychopathological profile is still present and becomes closer to that of the normative group after surgery. Further studies are needed to evaluate the effects of mild psychopathology on outcomes after bariatric surgery.

Changes in Eating Behaviors and Their Relation to Weight Change 6 and 12 Months After Bariatric Surgery

INTRODUCTION

Identifying eating behaviors associated with suboptimal weight loss following bariatric surgery remains important. This study assessed the relationship between eating behaviors and weight loss following bariatric surgery in a racially diverse sample.

METHODS

Participants were assessed before surgery and 6 and 12 months postoperatively, with the Structured Clinical Interview for DSM-5, the Eating Disorder Examination-Bariatric Surgery Version, and validated measures assessing a range of eating behaviors. Linear mixed effect models were used to test the impact of eating behaviors on percent weight loss (%WL) at 6 and 12 months.

RESULTS

We enrolled 300 participants (mean age 40.1 years; BMI 45.9 kg/m2; 87% women; 62% Black and 30% White). The majority (82%) underwent sleeve gastrectomy (SG). Mean %WL was 23.0 ± 5.1% at 6 months and 26.2 ± 7.6% at 12 months. Subjective binge episodes prior to surgery predicted greater %WL over the first 12 postoperative months (p = 0.028). Postoperative disinhibition, hunger, night eating symptoms, objective binge episodes, global disordered eating attitudes and behaviors, and snacks per day were associated with smaller %WL over 12 months (all p's < 0.01). The presence of picking/nibbling and addictive-like eating behaviors was not associated with %WL at the end of the first postoperative year.

CONCLUSION

Among a diverse participant sample, problematic eating behaviors following surgery were associated with smaller %WL over 12 months. Postoperative assessment and treatment of eating behaviors are needed to address these issues as they arise and to prevent attenuation of early weight loss in some patients.

Associations of COVID-19 Lockdowns on Eating Behaviors and Body Mass Index in Patients with a History of Bariatric Surgery: a Cross-Sectional Analysis

INTRODUCTION

Few studies have explored the impact of the COVID-19 pandemic on the eating behaviors, dietary quality, and changes in weight of postoperative bariatric surgery patients.

METHODS

A cross-sectional survey on eating behaviors and attitudes toward food was emailed or given to patients who had bariatric surgery before March 2020. Patient charts were reviewed for weight measures.

RESULTS

Seventy-five (71.43%) patients experienced weight recurrence with an average increase in body mass index (BMI) of 2.83 kg/m² (SD: 2.19). The majority of patients reported no symptoms of binge eating (n = 81, 77.14%) with 16 (15.24%) qualifying for loss of control eating (LOCE). LOCE was significantly associated with grazing behavior (p = 0.04), emotional over-eating (p = 0.001), and food responsiveness (p = 0.002). LOCE was negatively associated with dietary quality (p = 0.0009) and satiety responsiveness (p = 0.01). Grazing behavior was significantly associated with emotional over-eating (p < 0.0001) and food responsiveness (p < 0.0001) as well as negatively associated with dietary quality (p < 0.0001). Slow eating was negatively associated with grazing (p = 0.01), emotional over-eating (p = 0.003), and food responsiveness (p < 0.0001). When included in a regression model controlling for age and sex, emotional over-eating was a significant predictor of weight recurrence (β = 0.25; p = 0.04).

CONCLUSION

Our results suggest that maladaptive eating behaviors contributed to LOCE and poor dietary quality during the COVID-19 pandemic; however, slow eating may be protective against grazing, emotional over-eating, and food responsiveness.

Food insecurity, weight-based discrimination, weight self-stigma, and mental health in post-bariatric surgery patients

The United States Department of Agriculture defines food insecurity (FI) as reduced quality and variety of diet or overall reduced food intake. To date, limited research has investigated the relationship between FI, weight stigma, and bariatric surgery. The existing literature suggests that FI in bariatric surgery patients is significantly associated with being a person of color, depression, receiving Medicare or Medicaid, and higher eating disorder (ED) pathology. Research also suggests that weight stigma in bariatric surgery patients is associated with worsened weight loss outcomes. No research to our knowledge has investigated FI, internalized weight stigma, weight-based discrimination, and history of bariatric surgery in one sample. Bariatric surgery patients in this study (N = 266) reported elevated rates of FI relative to the general population, via an online questionnaire. Those with FI also reported higher rates of depression, anxiety, ED pathology, internalized weight stigma, and experiences of weight-based discrimination compared to those who were food secure. Given these findings, bariatric surgical centers should evaluate all potential patients for FI before surgery and, at the bare minimum, provide additional support before and post-surgery. The ethics of conducting bariatric surgery in those with FI who lack significant medical comorbidity also must be considered.

Three- and five-year follow-up results of a randomized controlled trial on the effects of cognitive behavioral therapy before bariatric surgery

OBJECTIVE

Up to 37% of bariatric surgery patients suffer from insufficient weight loss or weight regain and mental health symptoms in the longer term. Cognitive behavioral therapy (CBT) may be an effective adjunct intervention to optimize patients' psychological functioning and weight loss results. To examine the value of adding preoperative CBT to bariatric surgery, three- and five-year follow-up data are presented.

METHOD

In this multi-center randomized controlled trial (RCT; N = 130), a CBT group was compared to a treatment-as-usual (TAU) control group. Measurements were conducted at five time points: pretreatment (T0) and posttreatment/presurgery (T1) and at one- (T2; N = 120), three- (T3; N = 117), and five-year postsurgery (T4; N = 115). The intervention group received a 10-weeks, individual, preoperative CBT focused on self-monitoring, identifying triggers for disordered eating and goal setting for eating behavior and physical exercise, as well as postoperative lifestyle. Outcome measures included weight change, eating behavior, eating disorders, depression, quality of life (QoL), and overall psychological health.

RESULTS

Preoperative CBT was not associated with better three- and five-year results than TAU regarding weight, dysfunctional eating behaviors, eating disorders, depression, overall psychological health, and QoL.

DISCUSSION

Contrary to our hypothesis, three- and five-year postsurgery differences between groups regarding weight change and mental health were not significant.. Further exploration suggested that in both groups weight problems and depressive symptoms worsened at three and five-year follow-up. Future research should focus on long-term postoperative monitoring of weight and mood and on associated postoperative interventions and their specific timing.

PUBLIC SIGNIFICANCE

After bariatric surgery, in the longer term weight problems re-occur in 30% of patients, which is probably partly related to psychopathology. We investigated whether cognitive behavior therapy (CBT) prior to bariatric surgery improved weight maintenance and mental health after surgery. Our study provided definite proof that preoperative CBT is not effective. Long-term postoperative monitoring and prompt psychological intervention after first signs of deterioration, are important to prevent further problems.

An Updated Review of Night Eating Syndrome: An Under-Represented Eating Disorder

PURPOSE OF REVIEW

Night eating syndrome (NES) is an eating disorder that has historically been under-studied. The current review aims to summarize the most up-to-date research on NES to support better awareness.

RECENT FINDINGS

Since NES was recently included as a formal diagnosis, research on the prevalence of NES is ever evolving. Current studies underscore the high comorbidity between NES and other eating disorders, with additional complexities for patient with comorbid eating disorders. Recent findings also support the association between NES and sleep correlates, a relationship that has remained during the COVID-19 pandemic. Emerging research confirms correlates of distress in NES across cultures. There remain mixed findings between NES and BMI. There is also debate around whether age is a risk factor. Bariatric surgery research has focused on the re-emergence of NES post-operatively. Our understanding of the correlates of NES is increasing. However, research on the treatment for NES remains particularly under-studied and requires further attention.

Binge Eating Before and After Bariatric Surgery

PURPOSE OF REVIEW

The purpose is to review the state of the literature of binge eating in the context of bariatric surgery including prevalence, conceptualization, assessment, course, and related sequela throughout the perioperative continuum, particularly highlighting new advancements and future directions.

RECENT FINDINGS

Accurate assessment of binge eating in bariatric samples is essential for optimization of patient outcomes. Binge eating is less prevalent after bariatric surgery; however, prevalence rates increase over time. Most studies do not find a relationship between pre-operative binge eating and suboptimal weight outcomes after surgery. Refinement in understanding and conceptualization of post-operative binge eating is needed; new conceptualizations have proposed such a definition. Emerging constructs relevant to binge eating for bariatric patients include food addiction and food insecurity. Despite the introduction of formal diagnostic criteria for binge eating disorder, many uncertainties regarding the prevalence, course, and effects of binge eating currently exist; varied assessment methods continue to be a barrier to research on binge eating in bariatric surgery samples. Consensus on operational definitions for post-operative binge eating and best practices for assessment are areas for future consideration.

Food Addiction: A Comprehensive Review

Food addiction is associated with dysfunctions in the reward circuit, such as hyperresponsiveness during the exposure to high-calorie flavors in overweight and obese individuals. Similar to drug addiction, there is also impaired self-regulatory control supported by deregulation of the frontostriatal circuit. The inclusion of validated measures of food addiction in clinical research, such as the Yale Food Addiction Scale, has increased the understanding of the clinical utility of this concept. Furthermore, food addiction, eating disorders, and obesity are interrelated. Thus, it is important to recognize food addiction among individuals affected by obesity and candidates for bariatric surgery (ie, preoperative and postoperative assessment). In this context, it has been reported that food addiction may impede weight loss and increase the likelihood of regaining weight when associated with personality traits such as neuroticism and impulsiveness, which are also related to mood disorders, anxiety, and addictive behaviors.

Exploring the bidirectional relationships between night eating, loss of control eating, and sleep quality in Chinese adolescents: A four-wave cross-lagged study

OBJECTIVE

This study examined the bidirectional relationships between sleep quality, loss of control (LOC) eating, and night eating in Chinese adolescents using longitudinal data over an 18-month study period.

METHOD

Four-waves of data measurement (Waves 1-4), at 6-month intervals, were conducted with 2566 adolescents aged 11-17 years at baseline. A set of questionnaires were used to assess night eating, LOC eating, and sleep quality at each wave of data collection. Cross-lagged models were applied to analyze the bidirectional relationships between night eating, LOC eating, and sleep quality.

RESULTS

Results indicated that higher night eating scores consistently predicted poorer sleep quality and higher LOC eating scores at Waves 1, 2, and 3. Furthermore, poorer sleep quality predicted higher night eating scores at Wave 1 and Wave 3, and higher LOC eating scores predicted higher night eating scores at Wave 1 and Wave 2.

DISCUSSION

These findings highlight that night eating, LOC eating, and sleep quality were interrelated across time in Chinese adolescents. Improving sleep quality and reducing LOC eating might be promising in the prevention of night eating in adolescents. Similarly, reducing night eating might be promising in improving sleep quality and reducing LOC eating in adolescents.

PUBLIC SIGNIFICANCE

This study explored the bidirectional relationship between night eating, LOC eating, and sleep quality in Chinese adolescents using cross-lagged models. Findings indicate bidirectional relationships between these variables and highlight the potential utility in incorporating sleep, LOC eating, and night eating interventions in eating pathology prevention designs for adolescents.

Psychological impact of the COVID-19 pandemic on waitlisted pre-bariatric surgery patients in Saudi Arabia: A cross-sectional study

Background

During the COVID-19 pandemic, the number of bariatric surgeries was decreased to ensure patient safety. This study aimed to evaluate the effect of such delays on the psychological status and weight management behaviors of waitlisted pre-bariatric surgery patients in Jeddah, Saudi Arabia.

Materials and methods

A web-based cross-sectional survey was conducted. Results were then evaluated with simple descriptive statistics and inferential analyses through the Chi-square test, one-way ANOVA, and the general linear regression model.

Results

Of 437 patients, 208 successfully completed the survey. Approximately half of the participants reported weight change (46.6%, n = 97), while other weight management behaviors remained unchanged. The mean Patient Health Questionnaire-9 (PHQ-9) total score of the respondents was 8.29 ± 6.3, indicating mild depression. Higher PHQ-9 scores were associated with being a student, unhealthy dietary habits, physical inactivity, worsened psychological status, and weight gain. Among these factors, being a student was the strongest predictor of the total PHQ-9 score.

Conclusion

The COVID-19 pandemic significantly affected the psychological status of patients with obesity on the bariatric surgery waitlist. Since delays in bariatric surgeries could worsen patients’ psychological status, as substantiated in this study, the provision of virtual care through telemedicine and the development of policies for reintroducing bariatric surgeries for future lockdowns are highly recommended.

•

The mean PHQ-9 score of our subjects was 8.29 ± 6.3, indicating mild depression.

•

Higher PHQ-9 scores were linked with poor weight-management behaviors.

•

Being a student was the strongest predictor of the total PHQ-9 score.

Telephone-based cognitive behavioural therapy for patients with postoperative bariatric surgery to manage COVID-19 pandemic-related mental health issues and distress (TELE-BARICARE): a protocol for a randomised controlled trial

INTRODUCTION

Bariatric surgery is currently the most effective treatment for obesity, and is performed yearly in over 8000 patients in Canada. Over 50% of those who live with obesity also have a history of mental health disorder. The COVID-19 pandemic has made it difficult for people living with obesity to manage their weight even after undergoing bariatric surgery, which combined with pandemic-related increases in mental health distress, has the potential to adversely impact obesity outcomes such as weight loss and quality of life. Reviews of virtual mental health interventions during COVID-19 have not identified any interventions that specifically address psychological distress or disordered eating in patients with obesity, including those who have had bariatric surgery.

METHODS AND ANALYSIS

A randomised controlled trial will be conducted with 140 patients across four Ontario Bariatric Centres of Excellence to examine the efficacy of a telephone-based cognitive behavioural therapy intervention versus a control intervention (online COVID-19 self-help resources) in postoperative bariatric patients experiencing disordered eating and/or psychological distress. Patients will be randomised 1:1 to either group. Changes in the Binge Eating Scale and the Patient Health Questionnaire 9-Item Scale will be examined between groups across time (primary outcomes). Qualitative exit interviews will be conducted, and data will be used to inform future adaptations of the intervention to meet patients' diverse needs during and post-pandemic.

ETHICS AND DISSEMINATION

This study has received ethics approvals from the following: Clinical Trials Ontario (3957) and the University Health Network Research Ethics Committee (22-5145), the Board of Record. All participants will provide written informed consent prior to enrolling in the study. Results will be made available to patients with bariatric surgery, the funders, the supporting organisations and other researchers via publication in peer-reviewed journals and conference presentations.

TRIAL REGISTRATION NUMBER

NCT05258578.

DEVELOPMENT AND VALIDATION OF A PSYCHOLOGICAL SCALE FOR BARIATRIC SURGERY: THE BARITEST

BACKGROUND

It is recommended that bariatric surgery candidates undergo psychological assessment. However, no specific instrument exists to assess the psychological well-being of bariatric patients, before and after surgery, and for which all constructs are valid for both genders.

AIMS

This study aimed to develop and validate a new psychometric instrument to be used before and after bariatric surgery in order to assess psychological outcomes of patients.

METHODS

This is a cross-sectional study that composed of 660 individuals from the community and bariatric patients. BariTest was developed on a Likert scale consisting of 59 items, distributed in 6 constructs, which assess the psychological well-being that influences bariatric surgery: emotional state, eating behavior, quality of life, relationship with body weight, alcohol consumption, and social support. Validation of BariTest was developed by the confirmatory factor analysis to check the content, criteria, and construct. The R statistical software version 3.5.0 was used in all analyses, and a significance level of 5% was used.

RESULTS

Adjusted indices of the confirmatory factor analysis model indicate adequate adjustment. Cronbach's alpha of BariTest was 0.93, which indicates good internal consistency. The scores of the emotional state, eating behavior, and quality of life constructs were similar between the results obtained in the community and in the postoperative group, being higher than in the preoperative group. Alcohol consumption was similar in the preoperative and postoperative groups and was lower than the community group.

CONCLUSIONS

BariTest is a reliable scale measuring the psychological well-being of patients either before or after bariatric surgery.

Nonnormative Eating Behaviors and Eating Disorders and Their Associations With Weight Loss and Quality of Life During 6 Years Following Obesity Surgery

IMPORTANCE

Individuals with severe obesity presenting for obesity surgery (OS) frequently show nonnormative eating behaviors (NEBs) and eating disorders (EDs), but the long-term course and prospective associations with weight loss and health-related quality of life (HRQOL) remain unclear.

OBJECTIVE

To examine the prevalence and prospective relevance of presurgical and postsurgical NEBs and EDs according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, diagnosed through clinical interview, for weight loss and HRQOL up to 6 years following OS.

DESIGN, SETTING, AND PARTICIPANTS

In the prospective, multicenter Psychosocial Registry for Obesity Surgery cohort study, patients seeking OS were recruited at 6 OS centers in Germany and assessed at baseline before surgery and at 6 months and 1 to 6 years after surgery. From a consecutive sample of 1040 volunteers with planned OS from March 1, 2012, to December 31, 2020, a total of 748 (71.92%) were included in this study. Across follow-up, 93 of the 748 patients (12.43%) dropped out. Data were analyzed from April to November 2021.

INTERVENTIONS

Laparoscopic Roux-en-Y gastric bypass or sleeve gastrectomy.

MAIN OUTCOMES AND MEASURES

Both NEBs and EDs were identified using the Eating Disorder Examination interview. Main outcomes were the percentage of total body weight loss (%TBWL) and HRQOL (Impact of Weight on Quality of Life-Lite; range, 0-100, with 0 indicating worst and 100 indicating best).

RESULTS

In 748 patients undergoing OS (mean [SD] age, 46.26 [11.44] years; mean [SD] body mass index [calculated as weight in kilograms divided by height in meters squared], 48.38 [8.09]; 513 [68.58%] female), the mean (SD) %TBWL was 26.70% (9.61%), and the mean (SD) HRQOL improvement was 35.41 (20.63) percentage points across follow-up. Both NEBs and EDs were common before surgery, with postsurgical improvements of varying degrees. Whereas NEBs and EDs did not reveal significant prospective associations with %TBWL, loss-of-control eating at follow-up was concurrently associated with lower %TBWL (estimate, -0.09; 95% CI, -0.14 to -0.04). Loss-of-control eating (estimate, -0.10; 95% CI, -0.17 to -0.03 percentage points) and binge-eating disorder of low frequency and/or limited duration (estimate, -6.51; 95% CI, -12.69 to -0.34 percentage points) at follow-up showed significant prospective associations with lower HRQOL.

CONCLUSIONS AND RELEVANCE

This cohort study found prospective relevance of loss-of-control eating and binge-eating disorder of low frequency and/or limited duration for reduced long-term HRQOL following OS. These findings underline the importance of monitoring both NEBs, especially loss-of-control eating, and EDs in the long term postsurgically to identify patients in need of targeted prevention or psychotherapy.

PROBIOTIC SUPPLEMENTATION ATTENUATES BINGE EATING AND FOOD ADDICTION 1 YEAR AFTER ROUX-EN-Y GASTRIC BYPASS: A RANDOMIZED, DOUBLE-BLIND, PLACEBO-CONTROLLED TRIAL

AIM

The use of probiotics as adjuvants in the treatment of eating disorders, known as psychobiotics, has already been investigated as a means of modulating the microbiota-gut-brain axis. This study aimed to assess the effect of probiotic supplementation on binge eating and food addiction in subjects after Roux-en-Y gastric bypass surgery.

METHODS

This is a randomized, double-blind, placebo-controlled trial involving 101 patients who received probiotic (Lactobacillus acidophilus NCFM and Bifidobacterium lactis Bi-07) or placebo supplements for 90 days after bariatric surgery, starting on the seventh postoperative day. They were evaluated preoperatively (T0) and postoperatively at 90 days (T1) and 1 year (T2) after surgery. The Yale Food Addiction Scale (YFAS) and Binge Eating Scale (BES) were applied to assess food addiction and binge eating, respectively.

RESULTS

Before surgery, one-third of the patients presented with a food addiction and binge eating diagnosis. The number of symptoms of YFAS and the BES score decreased significantly in both groups at T1 compared to T0. However, a significant effect of treatment with probiotics was observed 1 year after surgery (T2). Both the number of symptoms of food addiction and the binge eating score were lower in the probiotic group than in the placebo group (p=0.037 and p=0.030, respectively).

CONCLUSION

The use of probiotic supplementation for 90 days in the immediate postoperative period may decrease food addiction symptoms and binge eating score up to 1 year after surgery compared to controls.

Proof of Concept for a Mindfulness-Informed Intervention for Eating Disorder Symptoms, Self-Efficacy, and Emotion Regulation among Bariatric Surgery Candidates

Up to 64% of patients seeking bariatric (weight-loss) surgery report eating disorder (ED) symptoms (addictive-like eating, binge eating, emotional eating, grazing) that can interfere with post-surgical weight loss. This prospective proof-of-concept study aimed to evaluate the impact of a pre-surgical mindfulness-informed intervention (MII) on ED symptoms and potential mechanisms-of-action to inform optimization of the intervention. Surgery-seeking adults attended four, 2-hour, MII sessions held weekly. Participants completed validated questionnaires assessing ED symptoms, eating self-efficacy, emotion regulation, and mindful eating pre-MII, post-MII, and at a 12-week follow-up. The MII consisted of mindfulness training, with cognitive, behavioral, and psychoeducational components. Fifty-six patients (M = 47.41 years old, 89.3% female) participated. Improvements in addictive-like eating, binge eating, emotional eating, and grazing were observed from pre- to post-MII. ED symptom treatment gains were either maintained or improved further at 12-week follow-up. Eating self-efficacy and emotion regulation improved from pre-MII to follow-up. Scores on the mindful eating questionnaire deteriorated from pre-MII to follow-up. In mediation analyses, there was a combined indirect effect of emotion regulation, eating self-efficacy, and mindful eating on grazing and binge eating, and an indirect effect of emotion regulation on emotional eating and addictive-like eating. Participation in the MII was associated with improvements in ED symptoms and some mechanisms-of-action, establishing proof-of-concept for the intervention. Future work to establish the MII's efficacy in a randomized controlled trial is warranted.

The Impact of Telephone-Based Cognitive Behavioral Therapy on Mental Health Distress and Disordered Eating Among Bariatric Surgery Patients During COVID-19: Preliminary Results from a Multisite Randomized Controlled Trial

Background

Patients undergoing bariatric surgery have high rates of psychiatric comorbidity, which may increase their vulnerability to COVID-19-related mental health distress. Exacerbation of mental health distress and disordered eating could have significant negative effects on long-term weight management and quality of life for these patients if untreated.

Objective

To determine the efficacy of a telephone-based cognitive behavioral therapy (Tele-CBT) intervention in improving depressive, anxiety, and disordered eating symptoms during COVID-19.

Methods

Participants were recruited as part of a larger randomized controlled trial study (clinicaltrials.gov ID: NCT03315247) between March 2020 and March 2021 and randomized 1:1 to receive Tele-CBT or standard bariatric care. Outcomes of Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), Emotional Eating Scale (EES), and Binge Eating Scale (BES) were measured at baseline, immediately post-intervention, and 3 months post-intervention. Linear mixed models were used to test the effect of intervention group, time, and group-by-time interaction for each outcome.

Results

Eighty-one patients were included in the intention-to-treat analysis. Mean (SD) age of participants was 47.68 (9.36) years and 80.2% were female. There were significant group-by-time interactions for all outcomes and significant differences between groups across time. There were significant decreases in mean GAD-7 (p = 0.001), PHQ-9 (p < 0.001), EES-Total (p = 0.001), EES-Anger (p = 0.003), EES-Anxiety (p < 0.001), EES-Depression (p < 0.001), and BES (p = 0.002) scores for the Tele-CBT group at post-intervention and follow-up when compared to baseline and the control group.

Conclusion

Tele-CBT is a feasible and effective treatment for improving psychological distress and disordered eating among post-operative bariatric surgery patients during the COVID-19 pandemic.

Examination of night eating and loss-of-control eating following bariatric surgery

PURPOSE

Post-operative loss-of-control (LOC)-eating is a negative prognostic indicator for long-term outcomes following bariatric surgery. Emerging research suggests that night eating might also be associated with poorer post-operative outcomes. This study examined the co-occurrence and clinical features of night eating in patients with LOC-eating following bariatric surgery.

METHODS

Participants were 131 adults who sought treatment for eating/weight concerns 6 months following sleeve gastrectomy. The Eating Disorder Examination (EDE) interview (Bariatric-Surgery-Version) assessed LOC-eating, regular night eating (at least weekly), and eating-disorder psychopathology. Participants completed the Night Eating Questionnaire (NEQ), Beck Depression Inventory (BDI-II), and the Pittsburgh Sleep Quality Index (PSQI).

RESULTS

Approximately, 15% met screening criteria for night-eating syndrome based on the NEQ. Greater NEQ scores were associated significantly with race, lower percent total weight loss (%TWL), and greater EDE, BDI-II, and PSQI scores. Similar results were observed when comparing groups with regular night eating (21.4%) versus without (78.6%); adjusting for race and %TWL revealed similar findings.

DISCUSSION

In post-bariatric patients with LOC-eating, 15% likely had night-eating syndrome and 21.4% engaged in regular night-eating behavior. The co-occurrence of LOC-eating and regular night eating following sleeve gastrectomy may represent a more severe subgroup with elevated psychopathology, poorer sleep and %TWL.

The Role of Resilience in Psychological Health Among Bariatric Surgery Patients

OBJECTIVE

Many individuals who undergo bariatric surgery have experienced repeated unsuccessful diet attempts and negative messages from healthcare providers, family, and others about their weight. Research pre- and post-operatively has taken a pathological or risk-based approach, investigating psychiatric problems and disordered eating. In contrast, the current study explores resilience in this population.

METHODS

Participants were 148 bariatric surgery patients. Participants completed measures pre-operatively and 1.5-3 years post-operatively, including the Binge Eating Scale, Eating Disorder Examination Questionnaire, Patient Health Questionnaire, Generalized Anxiety Questionnaire, Impact of Weight on Quality of Life, Coping Responses Inventory, and Duke Social Support and Stress Scales. The Connor-Davidson Resilience Scale was measured post-operatively.

RESULTS

Correlations demonstrated a significant association between post-operative resilience and lower symptoms of binge eating, disordered eating, depression, anxiety, and impact of weight on quality of life. Resilience was also associated with greater social support and less social stress, and greater use of approach coping strategies. Resilience was significantly associated with improvements in symptoms of binge eating, disordered eating, depression, anxiety, and impact of weight on quality of life from pre- to post-operative assessments. In regression models, associations remained significant after controlling for psychosocial variables at baseline (e.g., binge eating symptoms pre-operatively) and demographic covariates.

CONCLUSIONS

Psychological resilience has been under-studied in the literature on obesity and bariatric surgery, with a primary focus on risk factors for poor outcomes. This study was among the first to investigate associations between resilience and post-operative psychological outcomes. Results suggest the field would benefit from consideration of patient resilience in psychological assessments and interventions.

Night Eating Syndrome in Patients With Obesity and Binge Eating Disorder: A Systematic Review

Night eating syndrome (NES) is currently classified as an Other Specified Feeding or Eating Disorder (OSFED) under the Diagnostic Statistical Manual−5 (DSM-5). This systematic review aims to consolidate the studies that describe the sociodemographic, clinical and psychological features of NES in a population of patients with eating disorders (ED), obesity, or those undergoing bariatric surgery, and were published after the publication of the DSM-5. A further aim was to compare, where possible, NES with BED on the aforementioned variables. Lastly, we aimed to appraise the quality of the studies being included in the review. We conducted a systematic search on three databases (MEDLINE, PubMed and Embase) which resulted in the selection of 22 studies for the review. We included the articles that studied patients with NES and their sociodemographic, clinical and psychological features in a clinical (i.e., ED, obese or bariatric surgery) population, through a quantitative study design. Articles were excluded if the NES patients included in the study had a comorbid psychological disorder, and/or the sample was collected from a university/non-clinical population, and/or the study design was qualitative, and/or NES features were compared with any other disorder, except BED. Our study found that no conclusions about the link between any sociodemographic feature (such as, age, gender, income, etc.) and an NES diagnosis could be made. Further, NES patients presented with elevated ED pathology (including emotional eating and loss of control eating) and higher occurrence of depressive symptoms than controls. Contrary to the literature suggesting that NES and Binge Eating Disorder (BED; an ED subtype which is also comorbid with obesity) patients often report overlapping features, questioning the validity of NES as an ED diagnosis, we found that BED can be differentiated from NES by the higher occurrence of emotional eating, body related concerns and abnormal eating episodes. The review also suggested an overlap between NES and Sleep-Related Eating Disorder. We recommend that it is essential to study NES as an independent disorder to further develop its diagnostic criteria and treatment options, thereby, increasing the quality of life of the patients suffering from this syndrome.

Behavioral Interventions to Attenuate Driven Overeating and Weight Regain After Bariatric Surgery

Weight regain after bariatric surgery is associated with problematic eating behaviors that have either recurred after a period of improvement or are new-onset behaviors. Problematic eating behaviors after bariatric surgery have been conceptualized in different ways in the literature, such as having a food addiction and experiencing a loss of control of eating. The intersection of these constructs appears to be driven overeating defined as patients' experiences of reduced control of their eating which results in overeating behavior. The purpose of this review is to define patient experiences of driven overeating through the behavioral expression of emotion-based eating, reward-based eating, and executive functioning deficits-namely impulsivity-which is associated with weight regain after having bariatric surgery. Delineating concepts in this way and determining treatment strategies accordingly may reduce distress related to the inevitable return of increased hunger, cravings, portion sizes, and tolerance for highly palatable foods after surgery. Along with standard behavioral weight maintenance strategies, topics including acceptance, motivation, emotion-based eating, reward-based/impulsive eating, physical activity, and self-compassion are discussed. These concepts have been adapted for patients experiencing weight regain after having bariatric surgery and may be particularly helpful in attenuating driven overeating and weight regain.

Impact of Bariatric Surgery on the Healthy Eating Index, Binge Eating Behavior and Food Craving in a Middle Eastern Population: A Lebanese Experience

Even though bariatric surgeries (BS) are on the rise in Lebanon and the Middle East, the changes in diet quality, binge eating, and food cravings in this region are poorly studied peri-operatively. This cross-sectional study aimed to assess binge eating behaviors, food craving and the Healthy Eating Index (HEI) in Lebanese patients who underwent BS in a duration that exceeds 6 months. Evaluation included a dietary assessment of usual diet preoperatively and postoperatively. It included the collection of information on sociodemographic, anthropometric and surgical variables, as well as the administration of dietary recalls and questionnaires to calculate the HEI score, the Binge Eating Scale (BES) and the Food Craving Inventory (FCI). Participants (n = 60) were mostly females (85%) who had undergone sleeve gastrectomy (90%), with a mean duration since BS of 2.4 ± 1.8 years. Despite improvements in their HEI scores, 97% of the participants remained in the worst category. The frequency of participants in the severe BES category dropped markedly postoperatively from 78% to 5% (p < 0.01). Food craving followed a similar trend, with scores dropping from 50 ± 36 pre-surgery to 30 ± 25 post surgery (p < 0.01). Weight regain, prevalent among 40% of participants, was predicted by BES. Despite the improvement in BES and FCI, HEI improvement remained shy. Future interventions should validate findings in other countries and assess means for optimizing HEI scores among BS patients in the Middle East region.

Generalized Anxiety as a Risk Factor for Dysfunctional Eating Behavior after Obesity Surgery during the COVID-19 Pandemic

Purpose: The present study investigates the impact of obesity surgery on mental health (i.e., eating behavior and distress) during the COVID-19 pandemic. Methods: Two hundred fifty-four participants were recruited via social media. One hundred fourteen (44.53%) of them were surgery candidates (waiting for obesity surgery), while 142 (55.46%) had already undergone surgery. Participants who underwent surgery were compared to participants that did not yet undergo surgery in terms of mental burden (depression and anxiety), as well as safety and eating behavior. Further moderation analyses attempted to identify risk factors for increased COVID-19-related dysfunctional eating behavior after surgery. Results: Participants who underwent surgery showed generally lower levels of depression and general anxiety on a trend level. Moderation analyses suggested that people with high levels of generalized anxiety actually show more dysfunctional COVID-19-specific eating behavior after obesity surgery. Conclusion: On a trend level, obesity surgery appears to attenuate symptoms of generalized anxiety and depression. Yet, surgery patients with high levels of generalized anxiety exhibit even higher levels of dysfunctional eating during the COVID-19 pandemic. It is therefore particularly important to support people at risk.

A review of sex differences in the mechanisms and drivers of overeating

Disordered eating is often associated with marked psychological and emotional distress, and severe adverse impact on quality of life. Several factors can influence eating behavior and drive food consumption in excess of energy requirements for homeostasis. It is well established that stress and negative affect contribute to the aetiology of eating disorders and weight gain, and there is substantial evidence suggesting sex differences in sub-clinical and clinical types of overeating. This review will examine how negative affect and stress shape eating behaviors, and how the relationship between the physiological, endocrine, and neural responses to stress and eating behaviors differs between men and women. We will examine several drivers of overeating and explore possible mechanisms underlying sex differences in eating behavior.

Understanding bariatric patients' experiences of self-management post-surgery: A qualitative study

Although most bariatric patients achieve significant weight loss and improvements in both physical and mental health-related quality of life (HRQoL) in the short-term, there is wide variability in weight and long-term HRQoL outcomes. The role of bariatric patients' self-management style in explaining variability in long-term outcomes is unclear. This qualitative study examined bariatric patients' self-management experiences after bariatric surgery in relation to long-term outcomes. A qualitative study was conducted using semi-structured individual interviews with post-surgery patients (n = 23) at a Canadian bariatric surgery program. A constant comparative approach was used to systematically analyse the data and identify overarching themes. Variation in patients' experiences and follow-up time were the two primary units of analysis. Patients were predominantly female (n = 19; 82.6%) and had a mean age of 50 ± 8.49 years. The median time post-surgery was 2 years (range: 6 months-7 years). Three distinct phases described the process of self-management post-bariatric surgery: (1) rediscovering self-esteem and confidence in one's ability to self-manage (1-month to 1.5-years post-surgery), (2) achieving weight maintenance and addressing emotion dysregulation (1.5-3-years post-surgery) and (3) embracing a flexible balanced lifestyle (beyond 3-years). Bariatric surgery patients experience distinct challenges relative to their post-surgery time course. Facilitating access to interprofessional bariatric care after surgery allowed patients to acquire the self-management knowledge and skills necessary to address challenges to following the bariatric guidelines in the long-term.

Comparison of two questionnaires for assessment of emotional eating in people undergoing treatment for obesity

PURPOSE

Emotional eating may contribute to weight gain and difficulty with weight loss. Questionnaires are currently the primary method used to identify this behaviour but there is no gold standard for detecting emotional eating, making it difficult to know which questionnaire to use for this purpose. This study assesses two questionnaires validated for assessment of emotional eating in patients with obesity, with the aim of investigating their interchangeability in the clinical setting.

METHODS

387 adult participants were recruited from the obesity treatment service at a tertiary metropolitan hospital. Responses were obtained for the 25-item Emotional Eating Scale (EES) and the 4-item coping subscale of the Palatable Eating Motives Scale (PEMS). Agreement was analysed using quadratically weighted Cohen's κ scores. Substantial agreement was defined as κ 0.61-0.80.

RESULTS

The median (interquartile range) body mass index and age of participants was 42.1 kg/m² (36.4-48.9 kg/m²) and 51.6 years (41.1-61.4 years), respectively, and 70.5% of participants were female. The EES and PEMS were found to have substantial agreement (κ 0.71; 95% CI 0.65-0.76). Agreement remained substantial when analysing responses from men (0.61; 95% CI 0.47-0.73), women (0.73; 95% CI 0.67-0.79) and post-bariatric surgery patients (0.72; 95% CI 0.62-0.82) separately.

CONCLUSION

Despite focusing on different elements of emotional eating behaviour, the substantial agreement between the EES and PEMS coping subscale suggests that they identify respondents' susceptibility to emotional eating with consistency, including in people who have undergone bariatric surgery.

The psychological impact of COVID-19 pandemic on patients included in a bariatric surgery program

PURPOSE

The COVID-19 pandemic has radically impacted the world lifestyle. Epidemics are well-known to cause mental distress, and patients with a current or past history of obesity are at increased risk for the common presence of psychological comorbidities. This study investigates the psychological impact of the current pandemic in patients participating in a bariatric surgery program.

METHODS

Patients were consecutively enrolled during the Italian lockdown among those waiting for bariatric surgery or attending a post-bariatric follow-up, and were asked to complete through an online platform the Depression Anxiety Stress Scales-21 and a self-assessment questionnaire of 22 items evaluating the resilience, change in eating behavior and emotional responses referring to the ongoing pandemic.

RESULTS

59% of the 434 enrolled subjects reported of being worried about the pandemic, and 63% specifically reported of being worried about their or their relatives' health. 37% and 56% felt lonelier and more bored, respectively. 66% was hungrier with increased frequency of snacking (55%) and 39% reported more impulse to eat. Noteworthy, 49% felt unable to follow a recommended diet. No difference in terms of psychological profile was recorded among pre and post-bariatric subjects. Logistic regression analysis on post-bariatric patients showed a relationship between snacking, hunger, eating impulsivity, and anxiety, stress, and/or depression symptoms.

CONCLUSION

The pandemic led to increased psychological distress in patients with a current or past history of obesity, reducing quality of life and affecting dietary compliance. Targeted psychological support is warranted in times of increased stress for fragile subjects such as pre- and post-bariatric patients.

Body Image and Emotional Eating as Predictors of Psychological Distress Following Bariatric Surgery

BACKGROUND

The purpose of this study was to shed light on the ambiguity concerning the variables affecting psychological distress following bariatric surgery, specifically the roles of body image dissatisfaction (BID) and emotional eating in detecting and predicting such outcomes.

METHODS

Of 169 consecutive bariatric surgery candidates from a university-based bariatric center, who participated in the psychosocial pre-surgery survey from 2015 to 2017 (67% females, mean age 41.8 years (SD = 11.46), mean body mass index (BMI) 42.0 kg/m² (SD = 11.0)), 81 patients consented to be included in the follow-up phase (56% females, mean age 44.3 years (SD = 12.3, range 21-70), and BMI 30.1 kg/m² (SD = 6.2, range 19.7 to 56.2)). Risk of suicide (SBQ-R), depressive symptoms (PHQ-9), anxiety symptoms (PHQ-7), emotional eating behaviors (EES), and body image dissatisfaction (BID-BSQ8) measures were assessed before and after surgery.

RESULTS

Post-surgery improvements were observed in body image and emotional eating total measures, as well as in percent total weight loss (TWL%) and percent excess weight loss (EWL%), but not in psychological distress outcomes. However, improvement in BID predicted better post-surgery in all the psychological distress outcomes whereas improvement in emotional eating predicted less post-surgery depression. Post-surgery BID positively correlated with depression and anxiety, whereas post-surgery emotional eating positively correlated with anxiety.

CONCLUSIONS

Weight loss is insufficient to determine a change in psychological distress following surgery. Physicians and other health professionals who treat bariatric surgery patients should be encouraged to asses BID pre- and post-surgery, as it is a sensitive indicator of improvement of psychological well-being after surgery.

"If you're offered help, take it": A qualitative study examining bariatric patients' experience of telephone-based cognitive behavioural therapy

The increased recognition of patients' mental health needs after bariatric surgery has resulted in the emergence of accessible psychosocial interventions; however, there is a dearth of literature on patient experience and satisfaction with these interventions. We explored patients' perceptions and experiences of telephone-based cognitive behavioural therapy (Tele-CBT) in this qualitative study. Ten participants from the Toronto Western Hospital Bariatric Surgery Program in Toronto, Canada who completed the Tele-CBT (ClinicalTrials.gov Identifier: NCT02920112) were individually interviewed from November 2014 to June 2016 until thematic saturation occurred (ie, no more new coding groups emerged). Interviews were transcribed, independently coded, checked for discrepancies, and analysed using grounded theory. Four themes emerged: (1) participants were generally satisfied with Tele-CBT (eg, therapeutic alliance, resources provided, relevance of therapy to their own bariatric journey), (2) participants noticed emotional, cognitive, and behavioural changes following therapy, (3) the optimal time to deliver the Tele-CBT was when weight loss plateaued, generally at one-year post-surgery, and (4) participants found the telephone modality convenient. CBT was generally found to be helpful and the telephone format increased convenience and accessibility. Patients reported learning skills and receiving resources that could help them improve their well-being following bariatric surgery.

Addiction Transfer and Other Behavioral Changes Following Bariatric Surgery

Despite its important treatment implications for obesity and related comorbidities, bariatric surgery requires several behavioral changes that warrant comprehensive evaluation and support before and after surgery. This article outlines emerging scientific and anecdotal evidence for addiction transfer after bariatric surgery. Other common behavioral changes that impact adherence, weight loss, and psychiatric risk after surgery are also reviewed. Last, recommendations for presurgical psychological evaluation and postoperative support are provided.

Binge Eating After Bariatric Surgery in Patients Assisted by the Reference Service in a Brazilian Hospital and the Correlation with Weight Loss

PURPOSE

Identify, 18 months after bariatric surgery, the binge eating variation and its relation with weight regain or loss.

MATERIALS AND METHODS

Cross-sectional, retrospective study with 108 patients, assisted by an obesity walk-in clinic of a specialized hospital in São Paulo (Brazil), who had undergone bariatric surgery a minimum of 18 months previously. The anthropometric and clinic data were collected from medical records, and binge eating symptoms were evaluated with the application of the Binge Eating Scale (BES). Scale outcomes were related to weight regain and loss at the application moment.

RESULTS

The average age (standard error) of the sample was 47 years (±0.91) and 93% were female. Patients had lost 52.2% of their body weight and regained 4.7% of their weight 18 months after the surgery. The elapsed surgical time (> 50 months) was associated with a higher gross weight (p<0.0001).

CONCLUSIONS

Bariatric surgery has been shown to be effective for improving diabetes mellitus as well as for controlling obesity. The variation in binge eating intensity 18 months after bariatric surgery is a factor that interferes in the amount of weight regained. The presence of binge eating symptoms negatively affects the % total weight loss (%TWL).

The impact of COVID-19 pandemic on bariatric patients' self-management post-surgery

Background

The coronavirus disease 2019 (COVID-19) pandemic has had far reaching consequences on the health and well-being of the general public. Evidence from previous pandemics suggest that bariatric patients may experience increased emotional distress and difficulty adhering to healthy lifestyle changes post-surgery.

Objective

We aimed to examine the impact of the novel COVID-19 public health crisis on bariatric patients’ self-management post-surgery.

Method

In a nested-qualitative study, semi-structured telephone interviews were conducted with 23 post-operative bariatric patients who had undergone Roux-en-Y gastric bypass (RYGB) at a Canadian Bariatric Surgery Program between 2014 and 2020. A constant comparative approach was used to systematically analyze the data and identify the overarching themes.

Results

Participants (n = 23) had a mean age of (48.82 ± 10.03) years and most were female (n = 19). The median time post-surgery was 2 years (range: 6 months–7 years). Themes describing the impact of COVID-19 pandemic on patients’ post-bariatric surgery self-management included: coping with COVID-19; vulnerability factors and physical isolation; resiliency factors during pandemic; and valuing access to support by virtual care. The need for patients to access post-operative bariatric care during COVID-19 differed based on gender and socioeconomic status.

Conclusion

This study showed that the COVID-19 pandemic has impacted patients’ ability to self-manage obesity and their mental health in a variety of ways. These findings suggest that patients may experience unique psychological distress and challenges requiring personalized care strategies to improve obesity self-care and overall well-being.

Obesity as a multisystem disease: Trends in obesity rates and obesity-related complications

Obesity is a chronic multisystem disease associated with increased morbidity and mortality. The increasing prevalence of obesity makes it a major healthcare challenge across both developed and developing countries. Traditional measures such as body mass index do not always identify individuals at increased risk of comorbidities, yet continue to be used in deciding who qualifies for weight loss treatment. A better understanding of how obesity is associated with comorbidities, in particular non-metabolic conditions, is needed to identify individuals at risk in order to prioritize treatment. For metabolic disorders such as type 2 diabetes (T2D), weight loss can prevent T2D in individuals with prediabetes. It can improve and reverse T2D if weight loss is achieved early in the course of the disease. However, access to effective weight loss treatments is a significant barrier to improved health for people with obesity. In the present paper, we review the rising prevalence of obesity and why it should be classed as a multisystem disease. We will discuss potential mechanisms underlying its association with various comorbidities and how these respond to treatment, with a particular focus on cardiometabolic disease, malignancy and mental health.

The Bariatric Interprofessional Psychosocial Assessment of Suitability Scale predicts binge eating, quality of life and weight regain following bariatric surgery

Presurgical psychosocial evaluations are an important component of bariatric care; yet, bariatric programs vary widely in their assessment and interpretation of psychosocial risk. There is a need for validated clinical tools that help to standardize and streamline the assessment of variables relevant to surgical outcomes. The present study contributes to the validation of the Bariatric Interprofessional Psychosocial Assessment of Suitability Scale (BIPASS), a novel presurgical psychosocial evaluation tool, by: (a) examining the psychometric properties and optimal cutoff score, and; (b) examining the ability of the BIPASS tool to predict outcomes 1 and 2 years postsurgery, including weight regain, quality of life, psychiatric symptoms and adherence to postsurgical follow-up appointments. The BIPASS was applied retrospectively to the charts of 179 consecutively referred patients to a metropolitan bariatric surgery programme. Internal consistency for the BIPASS was acceptable, and interrater reliability was excellent. Higher BIPASS scores predicted higher binge eating symptomatology and lower mental health-related quality of life at 1 year postsurgery, and weight regain at 2 years (all P < .01). The BIPASS did not predict adherence to postsurgical follow-up appointments. Findings suggest that the BIPASS can be used to identify patients at increased risk of disordered eating, poor quality of life and weight regain early in the postsurgical course, thereby facilitating patient education and appropriate interventions.

Cognitive Behavioral Therapy Versus Usual Care Before Bariatric Surgery: One-Year Follow-Up Results of a Randomized Controlled Trial

BACKGROUND

Although early results of bariatric surgery are beneficial for most patients, some patients regain weight later. Cognitive behavioral therapy (CBT) has been suggested as a way to improve patients' psychological health and maintaining weight loss in the longer term. The added value of preoperative CBT to bariatric surgery was examined. Pre- and posttreatment and 1-year follow-up data are presented.

METHODS

In a multi-center randomized controlled trial, CBT was compared to a treatment-as-usual (TAU) control group. Measurements were conducted pre- and posttreatment/pre-surgery (T0 and T1) and at 1-year post-surgery (T2). Patients in the intervention group received 10 individual, weekly sessions of preoperative CBT focused on modifying thoughts and behaviors regarding eating behavior, physical exercise, and postoperative life style. Outcome measures included weight change, eating behavior, eating disorders, depression, quality of life, and overall psychological health.

RESULTS

Though no significant differences between conditions were found per time point, in the CBT, condition scores on external eating, emotional eating, depressive symptoms, and psychological distress decreased significantly more over time between pre- (T0) and posttreatment (T1) pre-surgery compared to TAU. No significant time x condition differences were found at 1-year post-surgery (T2).

CONCLUSIONS

Compared to TAU, preoperative CBT showed beneficial effects on eating behavior and psychological symptoms only from pretreatment to posttreatment/pre-surgery, but not from pre-surgery to 1-year post-surgery. Preoperative CBT does not seem to contribute to better long-term outcomes post-surgery. Recent studies suggest that the optimal time to initiate psychological treatment may be early in the postoperative period, before significant weight regain has occurred.

Relationship of personality characteristics and eating attitude with the success of bariatric surgery

Background: Obesity is a chronic disease that causes several medical and psychiatric complications. There are plenty of pharmacological and non-pharmacological therapies for obesity treatment. Bariatric surgery is one of the most efficient nonpharmacological treatment for morbid obesity; however, several psychological factors affect the success of bariatric surgery. This study aims to evaluate personality characteristics and eating attitude relationship with the success of bariatric surgery. Methods: This study was carried out on 75 patients with obesity who were candidates of bariatric surgery in the obesity clinic of Rasoul-e-Akram Hospital in Tehran. The patients were asked to fill the TCI and EAT-26 questionnaires before and after the surgery. Statistical analyses were performed using the SPSS-23 applying T-test, Mann-Whitney tests and Pearson and Spearman's correlation coefficient. The significance level was set at 0.05. Results: Seventy-five patients, including 13 men and 62 women, were assessed through this study. The mean of the BMI of the participants was 44.7 prior to the surgery and 30 after the operation. Personality characteristics and eating attitudes had no significant relationship with the success of bariatric surgery. Conclusion: Although the eating attitude and personal characteristics of the bariatric surgery candidates before the surgery was not related to the outcome of the surgery, they should be considered in post-operational psychological assessments.

Change in emotional eating after bariatric surgery: systematic review and meta-analysis

BACKGROUND

The effect of bariatric surgery on 'emotional eating' (EE) in people with obesity is unclear. This systematic review and meta-analysis aimed to examine changes in self-reported emotional eating behaviour after bariatric surgery.

METHODS

Fifteen electronic databases were searched from inception to August 2019. Included studies encompassed patients undergoing primary bariatric surgery, quantitatively assessed EE, and reported EE scores before and after surgery in the same participants. Studies were excluded if they were not in English or available in full text. The systematic review and meta-analysis were conducted according to the PRISMA guidelines. Random-effects models were used for quantitative analysis. Study quality was assessed using the National Heart, Lung, and Blood Institute quality assessment tool for before-after (pre-post) studies with no control group.

RESULTS

Some 23 studies containing 6749 participants were included in the qualitative synthesis, with follow-up of from 2 weeks to 48 months. EE scores decreased to 12 months after surgery. Results were mixed beyond 12 months. Quantitative synthesis of 17 studies (2811 participants) found that EE scores decreased by a standardized mean difference of 1·09 (95 per cent c.i. 0·76 to 1·42) 4-18 months after surgery, indicating a large effect size.

CONCLUSION

Bariatric surgery may mitigate the tendency to eat in response to emotions in the short to medium term.

The Impact of Coronavirus Disease 2019 on Bariatric Surgery: Redefining Psychosocial Care

The global outbreak of the 2019 novel coronavirus disease has had a tremendous psychological impact on individuals around the world. Individuals with obesity are susceptible to distress and psychological sequalae secondary to this pandemic, which can have detrimental effects on obesity management. In particular, individuals undergoing bariatric surgery could experience increased emotional distress, resulting in increased eating psychopathology, mental health exacerbation, and difficulties with self-management. Addressing these challenges requires novel approaches to redefining psychosocial care before and after bariatric surgery. Emerging evidence suggests that the remote delivery of care using virtual care models, including mobile and online modalities, could extend the reach of psychosocial services to individuals after bariatric surgery and mitigate weight regain or impairment in quality of life. Because of this pandemic, the rapid integration of virtual psychosocial care in bariatric surgery programs to address patients' needs will create new opportunities for clinical and implementational scientific research.

Perceived social support before and after bariatric surgery: association with depression, problematic eating behaviors, and weight outcomes

PURPOSE

Engaging in a healthy lifestyle after bariatric surgery is essential to optimize and sustain weight loss in the long term. There is promising evidence that social support of patients who undergo bariatric surgery plays an important role in promoting a better quality of life and adherence to the required behavioral changes and medical appointments. This study sought to investigate: (a) if post-operative patients experience different levels of perceived social support compared to pre-operative patients; (b) correlations between perceived social support, depression, disordered eating, and weight outcomes; (c) if social support is a moderator between psychological distress, and disordered eating behavior and weight outcomes.

METHODS

A group of 65 patients assessed pre-surgery and another group of 65 patients assessed post-surgery (M = 26.12; SD 7.97 months since surgery) responded to a set of self-report measures assessing social support, eating disorder psychopathology, disordered eating, and depression.

RESULTS

Greater social support was associated with lower depression, emotional eating, weight and shape concerns, and greater weight loss in pre- and post-surgery groups. Social support was found to be a moderator between different psychological/weight variables but only for the post-surgery group: the relation between depression and eating disorder psychopathology or weight loss was significant for patients scoring medium to high level is social support; the relation between grazing and weight regain was significant for patients scoring medium to low levels of social support.

CONCLUSIONS

The associations found between perceived social support and depression, disordered eating and weight outcomes highlight the importance of considering and working with the social support network of patients undergoing bariatric surgery to optimize treatment outcomes. Level of Evidence  Level III: case-control study.

Psychological outcomes following surgical and endoscopic bariatric procedures: A systematic review

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.

Psychiatric Management of Bariatric Surgery Patients: A Review of Psychopharmacological and Psychological Treatments and Their Impact on Postoperative Mental Health and Weight Outcomes

BACKGROUND

Bariatric surgery is an effective treatment for severe obesity; however, high rates of psychiatric comorbidity complicate bariatric surgery care. As a result, importance has been placed on the need for ongoing psychiatric support in patients undergoing bariatric surgery. Given the lack of conclusive presurgery psychosocial predictors of postoperative mental health outcomes, studies have now shifted their focus to understand the long-term psychosocial sequalae that arise after surgery. Increasing evidence has demonstrated the potential for psychiatric care to stabilize psychiatric symptoms and minimize patient distress.

OBJECTIVE

To review psychopharmacological and psychological interventions for patients undergoing bariatric surgery and their impact on mental health and weight outcomes after surgery.

METHODS

We performed a comprehensive literature search in Ovid MEDLINE for studies examining the impact of psychopharmacological and psychological treatments on bariatric patients' postoperative mental health and weight outcomes.

RESULTS

Overall, 37 studies were included in the review. Preliminary evidence suggests that psychiatric medications do not negatively impact weight loss or health-related quality of life in the short term; however, more rigorous research designs are needed. There are insufficient data on specific psychiatric medications and long-term impact on weight loss and psychosocial outcomes. Postoperative psychological interventions have evidence for improving eating psychopathology, anxiety, and depressive symptoms; however, effects on weight loss remain unclear.

CONCLUSION

Evidence for psychopharmacological and psychological treatments remains preliminary. Consideration should be given to integrated, stepped-care models to provide personalized psychiatric interventions after surgery. Future research on expanding current psychiatric interventions, timing of delivery, and predictors of response is needed.

Pre-operative Restraint and Post-operative Hunger, Disinhibition and Emotional Eating Predict Weight Loss at 2 Years Post-laparoscopic Adjustable Gastric Banding

INTRODUCTION

A principal mechanism of action in bariatric surgery is reduction in calorie consumption due to decreased hunger and increased satiety. Patients' ability to perceive post-operative changes to their hunger is therefore central to optimal results. This study examined factors that may impact how patients perceive post-operative hunger and how perception of hunger impacts eating and subsequent weight loss after laparoscopic adjustable gastric banding (LAGB).

METHODS

Patients undertaking LAGB (n = 147) provided pre-surgery and 2-year weight loss data and pre-surgery and 12-month psychological data (perception of hunger, disinhibition related to eating, emotional eating).

RESULTS

Path analysis demonstrated that patients with lower levels of pre-surgery cognitive restraint over eating experienced significantly greater reduction in perception of hunger at 12 months post-surgery. Perceived reduction in hunger was significantly associated with lower levels of both emotional eating and disinhibited eating. Finally, reduced emotional eating at 12 months significantly predicted 9% of the variance in percentage of total weight loss (%TWL) at 2 years after surgery.

CONCLUSION

These initial findings suggest that preparation for bariatric surgery may be enhanced by psychoeducation regarding cognitive restraint over eating and its effect on hunger perception. In addition, psychological treatment that focuses on identifying and responding to changes in hunger may contribute to improved outcomes for those who have difficulty adjusting to post-operative eating behaviours.

Night eating syndrome: a psychiatric disease, a sleep disorder, a delayed circadian eating rhythm, and/or a metabolic condition?

Introduction: Night Eating Syndrome (NES) refers to an abnormal eating behavior which presents as evening hyperphagia consuming >25% calorie intake and/or nocturnal awaking with food ingestion which occurs ≥2 times per week. Although the syndrome has been described more than seven decades ago, the literature has been growing slowly on its etiology, diagnosis, and treatment. Areas covered: The proposed treatment options for NES are all at a case-study level. Moreover, our understanding of its etiology, comorbidities, and diagnosis is still premature. We performed a literature review in Medline/PubMed to identify all the studies proposing a management plan for NES and summarized all the existing data on its diagnosis and treatment. Expert opinion: To date, none of the proposed treatment options for NES have been promising and long-term data on its efficacy is lacking. The slow growth of evidence on this debilitating but underreported condition may be due to unawareness among clinicians, under-reporting by patients, and unrecognized diagnostic criteria. Objective screening of symptoms during office visits especially for patients at a high-risk for NES will identify more patients suffering from the syndrome.

Psychosocial Predictors of Response to Telephone-Based Cognitive Behavioural Therapy in Bariatric Surgery Patients

OBJECTIVE

Bariatric surgery is an empirically supported treatment for severe obesity; however, it does not directly target underlying behavioural and psychological factors that potentially contribute to obesity. Mounting evidence supports the efficacy of cognitive behavioural therapy (CBT) for improving eating psychopathology and psychological distress among bariatric patients, and telephone-based CBT (Tele-CBT) is a novel delivery method that increases treatment accessibility.

METHODS

This study aimed to identify demographic and clinical predictors of response to Tele-CBT among 79 patients who received Tele-CBT in 3 previous studies. Listwise deletion was applied, after which 58 patients were included in a multivariate linear regression adjusted for age, sex and education status, to evaluate patient rurality index (urban or nonurban), and baseline binge eating, emotional eating and depression symptoms, as predictors of tele-CBT response.

RESULTS

The predictors explained 31% of the observed variance [R²=0.312, F(4,57)=3.238, p<0.01]. Patient rurality index (beta=0.341, p<0.01) was the only statistically significant predictor of Tele-CBT response.

CONCLUSIONS

Given the limited psychosocial resources available in many bariatric surgery programs, the findings suggest that Tele-CBT may be particularly beneficial for patients residing in nonurban communities with limited access to other health-care services.
