Binge eating disorder and eating self-efficacy in adults seeking bariatric surgery.

This study assessed the relationships between binge eating disorder (BED) and eating self-efficacy in a sample of patients prior to bariatric surgery. The study also examined the extent that BED status accounted for variance in self-efficacy after controlling for demographic factors (age, sex and race), physical variables (comorbidities and body mass index [BMI]) and depressive symptoms. This was a cross-sectional study of pre-surgical data from patients seeking bariatric surgery at a university-based healthcare system (N=98; mean ± SD age of 46.2 ± 12.5 years; BMI of 45.4 ± 7.2 kg/m2 ; 86.7% female; and 60.2% of patients self-identified as White). Patients completed the Weight and Lifestyle Inventory (WALI), Beck Depression Inventory-II (BDI-II) and Weight Efficacy Lifestyle Questionnaire. Of the total sample, 15.3% met criteria for BED, 33.7% had subthreshold BED and 51.0% were free of this disorder. In adjusted analyses, total self-efficacy was significantly lower in patients with subthreshold BED (B ± SE=-15.88 ± 7.23, p=.03) and individuals with BED (B ± SE=-35.07 ± 10.23, p=.001) than in those without BED. Patients with BED, compared to those without, had significantly worse scores (in adjusted analyses) on the self-efficacy subscales of negative emotions (p=.003), availability of food (p < .001), social pressure (p=.004) and positive activities (p=.03). In patients seeking bariatric surgery, total self-efficacy scores were significantly lower in patients with BED and subthreshold BED than those without BED. The results suggest that eating self-efficacy may be an important factor to target in patients with BED who seek bariatric surgery.

Relationship between Binge Eating Disorder (BED) and Development of Metabolic Syndrome (METs): A Systematic Review

Binge Eating Disorder (BED) or uncontrolled food consumption is strongly associated with metabolic syndrome as a significant risk factor for health. Metabolic Syndrome (MetS) is characterized by central adiposity, high-density lipoprotein (HDL) cholesterol, hypertriglyceridemia, hypertension, and increased fasting blood glucose. Approximately 9% of the general population suffer from Binge eating disorder (BED), a significant risk factor for Metabolic Syndrome (MetS). This study evaluates the association between Binge Eating disorder (BED) and Metabolic Syndrome (MetS) development through a systematic review. Through analysis of previous studies, we discovered that 93 percent of those with BED had metabolic syndrome parameters in a series of investigations on BED conducted in general care. This systematic review aims to connect the frequency of binge-eating episodes and the development of metabolic syndrome. We have extracted five major studies (n = 5) through screening following systematic review standards.

Sleep dysregulation in binge eating disorder and "food addiction": the orexin (hypocretin) system as a potential neurobiological link.

It has been proposed that binge eating reflects a pathological compulsion driven by the "addictive" properties of foods. Proponents of this argument highlight the large degree of phenomenological and diagnostic overlap between binge eating disorder (BED) and substance use disorders (SUDs), including loss of control over how much is consumed and repeated unsuccessful attempts to abstain from consumption, as well as commonalities in brain structures involved in food and drug craving. To date, very little attention has been given to an additional behavioral symptom that BED shares with SUDs-sleep dysregulation-and the extent to which this may contribute to the pathophysiology of BED. Here, we review studiesexamining sleep outcomes in patients with BED, which collectively point to a heightened incidence of sleep abnormalities in BED. We identify the orexin (hypocretin) system as a potential neurobiological link between compulsive eating and sleep dysregulation in BED, and provide a comprehensive update on the evidence linking this system to these processes. Finally, drawing on evidence from the SUD literature indicating that the orexin system exhibits significant plasticity in response to drugs of abuse, we hypothesize that chronic palatable food consumption likewise increases orexin system activity, resulting in dysregulated sleep/wake patterns. Poor sleep, in turn, is predicted to exacerbate binge eating, contributing to a cycle of uncontrolled food consumption. By extension, we suggest that pharmacotherapies normalizing orexin signaling, which are currently being trialed for the treatment of SUDs, might also have utility in the clinical management of BED.

Binge eating disorder and depressive symptoms among females of child-bearing age: the Korea Nurses' Health Study

BackgroundMost studies regarding the relationship between binge eating disorder (BED) and depression have targeted obese populations. However, nurses, particularly female nurses, are one of the vocations that face these issues due to various reasons including high stress and shift work. This study investigated the prevalence of BED and the correlation between BED and severity of self-reported depressive symptoms among female nurses in South Korea.MethodsParticipants were 7,267 female nurses, of which 502 had symptoms of BED. Using the propensity score matching (PSM) technique, 502 nurses with BED and 502 without BED were included in the analyses. Data were analyzed using descriptive statistics, Spearman’s correlation, and multivariable ordinal logistic regression analysis.ResultsThe proportion of binge eating disorder was 6.90% among the nurses, and 81.3% of nurses displayed some levels of depressive symptoms. Multivariable ordinal logistic regression analysis revealed that age (40 years old and older), alcohol consumption (frequent drinkers), self-rated health, sleep problems, and stress were associated with self-reported depression symptoms. Overall, after adjusting for confounders, nurses with BED had 1.80 times the risk (95% CI = [1.41–2.30]; p-value < 0.001) of experiencing a greater severity of self-reported depression symptoms.ConclusionsKorean female nurse showed a higher prevalence of both binge eating disorder and depressive symptoms, and the association between the two factors was proven in the study. Therefore, hospital management and health policy makers should be alarmed and agreed on both examining nurses on such problems and providing organized and systematic assistance.

The Relationship between Binge Eating Disorder and Suicidality: A Systematic Review.

Background: We carried out a systematic review analyzing the relation between binge eating disorder (BED), a recent addition to the eating disorders in DSM-5, and suicidality (i.e., suicidal ideation or attempted and/or committed suicide) by synthesizing the relevant studies' qualitative data.Methods: We conducted, according to PRISMA guidelines, a systematic search of the literature on PubMed, Scopus, ISI Web of Science, PsycINFO, Google Scholar, and ScienceDirect. Search terms were “binge eating disorder” combined with the “AND” Boolean operator and “suicid*.”Results: The initial search identified 4,014 records, of which 17 research reports met the predefined inclusion criteria and were analyzed. BED was found to be significantly associated with a marked increase in suicidal behaviors and suicidal ideation (SI). The presence and severity of BED were found to be relevant predictive factors for suicidality, notably in association with mood disorders and specific psychological features, while a high body mass index (BMI) did not always affect suicidality. BED has usually been associated with suicide risk, particularly when occurring with another psychiatric disorder and/or in an adolescent population.Conclusion: Pursuant to these findings, it is necessary to consider both dysfunctional eating behavior and related psychopathological factors that may induce SI and suicidal behavior in BED, aiming to identify patients and subgroups of patients needing greater clinical psychological attention to most effectively prevent and treat suicidality.

Binge Eating Disorder and Substance Use Disorder: A Case for Food Addiction

We review literature regarding the symptomatic and neurological similarities between Binge Eating Disorder (BED) and Substance Use Disorder (SUD) in order to make a case for the inclusion of “Food Addiction” (FA) in future versions of the Diagnostic and Statistical Manual of Mental Disorders (DSM). FA is defined by a markedly harmful and addictive cycle of compulsive eating, which requires professional intervention and treatment strategies. We argue that FA is a scientifically sound diagnosis due to the addictive-like compulsive overeating behavior that has major similarities with SUDs. Similarities occur among the symptoms of the disorders, the chemical components within the disorders, and the neurological details related to each of the disorders. Some symptom similarities include the descriptor of consuming “large amounts” of the substance (i.e., food), experience of dependence and withdrawal, and “self-medicating” behavior. We conclude that the compulsive overeating that defines BED is distinctively similar to substance addictions and that this consistent overlap provides reason for FA to be accepted as a diagnosis in the DSM.

Food Addiction, Binge Eating Disorder, and Obesity: Is There a Relationship?

Existing research suggests that there is an overlap between binge eating disorder (BED) and the construct of ‘food addiction’ (FA). The objective of this study was to determine the overlapping features of BED and FA through a comparison of the individual scales of commonly used tools including the Binge Eating Scale (BES) and the Yale Food Addiction Scale (YFAS) in a sample of Australian adults. Adults (>18 years of age) were invited to complete an anonymous online survey on FA. Binge eating was assessed through the BES and addictive eating behaviours were assessed through the YFAS (n = 1344). The prevalence and severity of both FA and binge eating increased across weight categories. The overall correlation between the total score from the BES and FA symptoms was r = 0.76, p < 0.001; for females it was r = 0.77, p < 0.001, and for males it was r = 0.65, p < 0.001. Total BES score and the BES emotion factor were most often associated with FA symptoms, as was demonstrated to produce stronger correlations with FA symptoms. In contrast, the BES behaviour factor was less strongly associated to FA with the majority of correlations <0.6. This study demonstrates the overlap between BED and FA, and highlights the possible unique differences between the forms of disordered eating.

Binge‐eating disorder in the Swedish national registers: Somatic comorbidity

ABSTRACTObjectiveTo evaluate associations between binge‐eating disorder (BED) and somatic illnesses and determine whether medical comorbidities are more common in individuals who present with BED and comorbid obesity.MethodCases (n = 850) were individuals with a BED diagnosis in the Swedish eating disorders quality registers. Ten community controls were matched to each case on sex, and year, month, and county of birth. Associations of BED status with neurologic, immune, respiratory, gastrointestinal, skin, musculoskeletal, genitourinary, circulatory, and endocrine system diseases were evaluated using conditional logistic regression models. We further examined these associations by adjusting for lifetime psychiatric comorbidity. Amongst individuals with BED, we explored whether comorbid obesity was associated with risk of somatic disorders.ResultsBED was associated with most classes of diseases evaluated; strongest associations were with diabetes [odds ratio (95% confidence interval) = 5.7 (3.8; 8.7)] and circulatory systems [1.9 (1.3; 2.7)], likely indexing components of metabolic syndrome. Amongst individuals with BED, those with comorbid obesity were more likely to have a lifetime history of respiratory [1.5 (1.1; 2.1)] and gastrointestinal [2.6 (1.7; 4.1)] diseases than those without comorbid obesity. Increased risk of some somatic disease classes in individuals with BED was not simply due to obesity or other lifetime psychiatric comorbidity.DiscussionThe association of BED with many somatic illnesses highlights the morbidity experienced by individuals with BED. Clinicians treating patients with BED should be vigilant for medical comorbidities. Nonpsychiatric providers may be the first clinical contact for those with BED underscoring the importance of screening in primary care. © 2016 The Authors International Journal of Eating Disorders Published by Wiley Periodicals, Inc.

Suicidality in adolescents and adults with binge-eating disorder: Results from the national comorbidity survey replication and adolescent supplement.

The relation between binge-eating disorder (BED) and suicidality (i.e., suicide ideation, plan, and/or attempt) has not been studied extensively, and it is unknown whether BED is uniquely associated with suicidality when adjusting for comorbid psychopathology. Moreover, the course of suicidality in BED has not been determined and it is unknown whether BED precedes suicidality or vice versa. A total of 10,123 adolescents and 2,980 adults from two nationally representative surveys were administered diagnostic interviews assessing psychopathology and suicidality, as well the retrospectively reported ages of onset. Among adults and adolescents, BED was associated with elevated odds of suicide ideation, plan, and attempt at a univariate level, but BED was not associated with elevated odds of suicidality when adjusting for comorbid psychopathology. Kaplan-Meier estimates of temporal patterns displayed that most adolescents experienced suicidality onset following BED onset, whereas most adults experienced suicidality onset prior to BED onset. BED, comorbid disorders, and suicidality share common factors and interrelations, and individuals with BED and comorbid disorders may be at particularly high risk for suicidal outcomes. The presence of BED in adolescence may serve as a marker for more severe symptomatology that precedes the occurrence of suicidality. Research is needed to understand how eating disorder symptoms, comorbid symptoms, and suicidality affect one another over time. © 2016 Wiley Periodicals, Inc. (Int J Eat Disord 2017; 50:40-49).

Life adverse experiences in relation with obesity and binge eating disorder: A systematic review.

Background and aimsSeveral studies report a positive association between adverse life experiences and adult obesity. Despite the high comorbidity between binge eating disorder (BED) and obesity, few authors have studied the link between trauma and BED. In this review the association between exposure to adverse life experiences and a risk for the development of obesity and BED in adulthood is explored.MethodsBased on a scientific literature review in Medline, PubMed and PsycInfo databases, the results of 70 studies (N = 306,583 participants) were evaluated including 53 studies on relationship between adverse life experiences and obesity, 7 studies on post-traumatic stress disorder (PTSD) symptoms in relation to obesity, and 10 studies on the association between adverse life experiences and BED. In addition, mediating factors between the association of adverse life experiences, obesity and BED were examined.ResultsThe majority of studies (87%) report that adverse life experiences are a risk factor for developing obesity and BED. More precisely a positive association between traumatic experiences and obesity and PTSD and obesity were found, respectively, in 85% and 86% of studies. Finally, the great majority of studies (90%) between trauma and the development of BED in adulthood strongly support this association. Meanwhile, different factors mediating between the trauma and obesity link were identified.Discussion and conclusionsAlthough research data show a strong association between life adverse experiences and the development of obesity and BED, more research is needed to explain this association.

Individual differences in negative affect and weekly variability in binge eating frequency

To examine the relationship of neuroticism and negative affect (NA) lability with weekly binge eating fluctuations between binge eating disorder (BED) and bulimia nervosa (BN). Individuals with BED (n = 30) and BN (n = 54) from the community completed self-report measures at baseline and prospectively for 12 consecutive weeks. Weekly data were analyzed by using (mean) squared successive deviation to account for fluctuations in NA and binge eating from week to week. Generalized estimating equations revealed the presence of a two-way interaction between neuroticism and NA lability predicting binge eating fluctuations (Wald χ(2) = 8.25; df = 1; p = .004), indicating that higher NA lability was only related to larger fluctuations in the frequency of binge eating episodes when present in individuals who were also high on neuroticism. An interaction was also detected between eating disorder diagnosis and NA lability, but this was accounted for by differences in average NA between the diagnoses. This study highlights the relevance of two traits and their interaction in understanding individual differences in binge eating fluctuations. Additionally, findings indicate that diagnostic differences in average NA may impact binge eating fluctuations and NA lability.

Clinical phenotype of bipolar disorder with comorbid binge eating disorder

BackgroundTo explore the relationship between binge eating disorder (BED) and obesity in patients with bipolar disorder (BP). Methods717 patients participating in the Mayo Clinic Bipolar Biobank completed structured diagnostic interviews and questionnaires for demographic and illness-related variables. They also had weight and height measured to determine body mass index (BMI). The effects of BED and obesity (BMI≥30kg/m2), as well as their interaction, were assessed on one measure of general medical burden and six proxies of psychiatric illness burden. Results9.5% of patients received a clinical diagnosis of BED and 42.8% were obese. BED was associated with a significantly elevated BMI. Both BED and obesity were associated with greater psychiatric and general illness burden, but illness burden profiles differed. After controlling for obesity, BED was associated with suicidality, psychosis, mood instability, anxiety disorder comorbidity, and substance abuse comorbidity. After controlling for BED status, obesity was associated with greater general medical comorbidity, but lower substance abuse comorbidity. There were no significant interaction effects between obesity and BED, or BMI and BED, on any illness burden outcome. LimitationsThere may have been insufficient power to detect interactions between BED and obesity. ConclusionsAmong patients with BP, BED and obesity are highly prevalent and correlated, but associated with different profiles of enhanced illness burden. As the association of BED with greater psychiatric illness burden remained significant even after accounting for the effect of obesity, BP with BED may represent a clinically important sub-phenotype.

Assessment of interpersonal skills in obese women with binge eating disorder

Based upon interpersonal theory that suggests an association between binge eating disorder (BED) and interpersonal problems, the present study examined empathy and other social skills of obese women with BED. The findings showed that five social skills were statistically associated with the chance of presenting BED. Obese women with less assertiveness, lower ability to express feelings, lower capacity to deal with strangers, lower ability to understand the perspective of others, and with higher levels of distress in interpersonal situations had a higher probability of presenting the diagnosis of BED. These results highlight an association between social skills deficits and BED.

Nighttime eating: A descriptive study

The definition of night eating syndrome (NES) is inconsistent across various studies and literatures. The goal of the current descriptive study was to collect data on participants who were selected using broad criteria for nighttime eating. Researchers have cogently argued for consideration of wide ranges including "subsyndromal" cases before reifying diagnostic constructs prematurely. One-hundred six participants with broadly defined nighttime eating problems were recruited through newspaper advertisements and were interviewed over the phone. The following instruments were administered: the Night Eating Questionnaire, the Night Eating Syndrome History and Inventory, the Eating Disorder Questionnaire, the Structured Clinical Interview for DSM-IV diagnoses and a Sleep Disorder Questionnaire. Thirty-one (29.2%) participants met the original criteria described by Stunkard et al. (Am J Med 1955;19:78) and only 14 (13.2%) participants met all of the most recent proposed criteria for NES (Birketvedt et al., JAMA 1999;282:657). The overlap between binge eating disorder (BED) and nighttime eating problems was modest in our sample with only 9 participants meeting current BED criteria. One half of our sample was obese. Regular nocturnal eating was reported by 57.5% of the participants. Dieting was not a frequent precursor or antecedent of nocturnal eating. However, self-reported current parasomnias were quite frequent in our sample. Our descriptive study confirms some of the observations made by other researchers. Nevertheless, nighttime eating is still an evolving concept that requires close collaboration between eating and sleep researchers.

Binge-eating episodes are not characteristic of carriers of melanocortin-4 receptor gene mutations.

Recently, Branson and coworkers reported a strong association between binge-eating disorder (BED) and variants in the melanocortin-4 receptor gene (MC4R). In the current study, we compared the eating behavior of 43 obese probands with functionally relevant MC4R mutations and of 35 polymorphism carriers (V103I or I251L) with wild-type carriers. The module for eating disorders of the Composite International Diagnostic Interview was used to identify binge-eating behavior. The Three-Factor Eating Questionnaire and the Leeds Food Frequency Questionnaire were used to assess restrained eating, disinhibition, hunger and percent total energy intake as fat. No significant differences between carriers of MC4R variants and wild-type carriers were detected. In particular, we found no evidence for an increased rate of binge-eating behavior in obese carriers of MC4R variants. Our findings do not support the strong association between BED and MC4R carrier status.
