Small bowel obstruction on food impaction after binge eating.

Small bowel obstruction is a relatively prevalent surgical condition, with the most common underlying cause being postoperative adhesions. However, in patients with no previous history of abdominal surgery, one needs to think more outside the box. In this case study, we have a young and athletic man who presented to the emergency department with an acute abdomen, shortly after binge eating a large amount of food. Obstruction due to food impaction, such as in our case, should always be on the differential list, especially in those without significant medical history and with binge eating pattern where uncontrolled and extreme amounts of food are eaten alternating with restrictive dieting.

Weight excess and obesity are associated with binge-eating behaviours in people with HIV.

OBJECTIVE: Binge eating is a mental health disorder related to weight gain, whose prevalence/correlation with weight excess in people with HIV (PWH) have been scarcely investigated.Design: A cross-sectional study of PWH who underwent the validated Binge Eating Scale (BES) questionnaire. METHODS: We included adult PWH during routine visits from October 2022 to February 2023. The BES questionnaire was administered with the support of a psychiatrist (score <17 binge eating very unlikely, binge eating ≥17 possible/very likely). We performed a logistic regression for the binary outcome BES at least 17 and being overweighted/obese as effect measure of risk association, and then adjusted for possible confounders (as integrase inhibitor exposure) and performed a sensitivity analysis fitting the regression model including and excluding depression (which may drive binge eating). RESULTS: We included 1204 PWH, 75.2% men, median age 53 years [interquartile range (IQR): 44-60], 95.6% with undetectable HIV-RNA. As for BMI, we had overweight and obesity in 35.1 and 19.4% cases. Considering BES, 1089 (90.4%) PWH had a score less than 17, 115 (9.6%) at least 17. Multivariable analysis showed that obesity [odds ratio (OR) = 6.21, P  < 0.0001), overweight (OR = 2.21, P  = 0.006) and depression (OR = 1.98, P  = 0.028) were significantly associated with high BES score. By excluding depression, our results were confirmed, and obesity/overweight remained significantly associated with binge eating (obesity OR = 6.58, P  < 0.0001, overweight OR = 2.17, P  = 0.023). CONCLUSION: Binge eating should be considered among possible causes of weight gain in PWH. Our results push towards an in-depth study of this topic for a better understanding of the phenomenon in PWH, possibly identifying subgroups of this population who could benefit from a psychoeducational/psychological intervention to preventing WG.

Association Between Type 1 Diabetes Mellitus and Eating Disorders: A Systematic Review and Meta-Analysis.

BACKGROUND: Previous meta-analyses have shown mixed results regarding the association between eating disorders (EDs) and type 1 diabetes mellitus (T1DM). Our paper aimed to analyse different EDs and disordered eating behaviours that may be practiced by patients with T1DM. METHODS: A literature search of PubMed, Scopus and Web of Science was conducted on 17 January 2023, using the key terms "T1DM," "Eating Disorders" and "Bulimia." Only observational controlled studies were included. The Revman software (version 5.4) was used for the analysis. RESULTS: T1DM was associated with increased risk of ED compared with nondiabetic individuals (RR = 2.47, 95% CI = 1.84-3.32, p-value < 0.00001), especially bulimia nervosa (RR = 2.80, 95% CI = 1.18-6.65, p-value = 0.02) and binge eating (RR = 1.53, 95% CI = 1.18-1.98, p-value = 0.001). Our analysis has shown that increased risk of ED among T1DM persisted regardless of the questionnaire used to diagnose ED; DM-validated questionnaires (RR = 2.80, 95% CI = 1.91-4.12, p-value < 0.00001) and generic questionnaires (RR = 2.03, 95% CI = 1.27-3.23, p-value = 0.003). Prevalence of insulin omission/misuse was 10.3%; diabetic females demonstrated a significantly higher risk of insulin omission and insulin misuse than diabetic males. CONCLUSION: Our study establishes a significant and clear connection between EDs and T1DM, particularly bulimia and binge eating, with T1DM. Moreover, female diabetics are at higher risk of insulin misuse/omission. Early proactive screening is essential and tailored; comprehensive interventions combining diabetes and ED components are recommended for this population, with referral to a specialised psychiatrist.

Binge eating symptomatology in adolescents with polycystic ovary syndrome.

Several factors may contribute to binge eating behaviors in PCOS. However, findings are contradictory and studies in the adolescence are limited. We aimed to evaluate the eating attitudes of adolescents with PCOS and the possible etiological factors underlying the association between PCOS and binge eating symptomology. Between 2019 and 2022, 46 newly diagnosed adolescents with PCOS and 56 controls matched for age and BMI z-score were included. The Eating Disorder Examination Questionnaire, Three Factor Eating Questionnaire-R18, and a questionnaire assessing postprandial reactive hypoglycemia symptom severity were given. Binge eating symptomology, in terms of over, uncontrolled, and emotional eating, were more prevalent in the PCOS group. Uncontrolled, emotional, and binge eating were positively correlated with postprandial reactive hypoglycemia symptom score. Overeating was also associated with clinical hyperandrogenism. Improving the disease outcome and reducing the future complications requires early recognition and management of emotional and uncontrolled eating behaviors in adolescents with PCOS.

Eating disorder psychopathology, psychiatric impairment, and symptom frequency of atypical anorexia nervosa versus anorexia nervosa: A systematic review and meta-analysis.

OBJECTIVES: Restrictive eating disorders (EDs) occur across the weight spectrum, but historically more focus has been given to anorexia nervosa (AN) than atypical anorexia nervosa (atypAN). AtypAN's relegation to a diagnosis in the "other specified feeding and eating disorder" (OSFED) category and paucity of research surrounding atypAN invariably implies a less clinically severe ED. However, a growing body of research has begun to question the assumption that atypAN is less severe than AN. The current review and meta-analysis aimed to provide a comprehensive review to compare atypAN and AN on measures of eating disorder psychopathology, impairment, and symptom frequency to test whether atypAN is truly less clinically severe than AN. METHODS: Twenty articles that reported on atypAN and AN for at least one of the variables of interest were retrieved from PsycInfo, PubMed, and ProQuest. RESULTS: For eating-disorder psychopathology, results indicated that differences were nonsignificant for most indicators; however, atypAN was associated with significantly higher shape concern, weight concern, drive for thinness, body dissatisfaction, and overall eating-disorder psychopathology than AN. Results indicated that atypAN and AN did not significantly differ on clinical impairment or the frequency of inappropriate compensatory behaviors, whereas there was a significantly higher frequency of objective binge episodes in AN (vs. atypAN). DISCUSSION: Overall, findings indicated that, in contrast to the current classification system, atypAN and AN were not clinically distinct. Results underscore the need for equal access to treatment and equal insurance coverage for restrictive EDs across the weight spectrum. PUBLIC SIGNIFICANCE: The current meta-analysis found that atypAN was associated with higher drive for thinness, body dissatisfaction, shape concern, weight concern, and overall eating-disorder psychopathology than AN; whereas AN was associated with higher frequency of objective binge eating. Individuals with AN and atypAN did not differ on psychiatric impairment, quality-of-life, or frequency of compensatory behaviors, highlighting the need for equal access to care for restrictive EDs across the weight spectrum.

OBJETIVO: Los trastornos alimentarios restrictivos ocurren en todo el espectro de peso, pero históricamente se ha dado más importancia a la anorexia nerviosa (AN) que a la anorexia nerviosa atípica (ANA). El hecho de relegar la anorexia nerviosa atípica a un diagnóstico en la categoría de "otro trastorno de la ingestión de alimentos y de la conducta alimentaria" (OSFED) y la escasez de investigación en torno a la anorexia atípica, implica invariablemente un trastorno de la conducta alimentaria clínicamente menos grave. Sin embargo, un creciente cuerpo de investigación ha comenzado a cuestionar la suposición de que ANA es menos grave que AN. La revisión actual y el metanálisis tuvieron como objetivo proporcionar una revisión exhaustiva para comparar ANA y AN en las medidas de psicopatología de los trastornos alimentarios, el deterioro y la frecuencia de los síntomas para probar si ANA es realmente menos grave clínicamente que AN. MÉTODO: Veinte artículos que informaron sobre ANA y AN para al menos una de las variables de interés se recuperaron de PsycInfo, PubMed y ProQuest. RESULTADOS: Para la psicopatología del trastorno alimentario, los resultados indicaron que las diferencias no fueron significativas para la mayoría de los indicadores; sin embargo, ANA se asoció con una preocupación de forma significativamente mayor, preocupación por el peso, impulso por la delgadez, insatisfacción corporal y psicopatología general del trastorno alimentario que AN. Los resultados indicaron que ANA y AN no difirieron significativamente en el deterioro clínico o la frecuencia de comportamientos compensatorios inapropiados, mientras que hubo una frecuencia significativamente mayor de episodios de atracones objetivos en AN (frente a ANA). DISCUSIÓN: En general, los hallazgos indicaron que, en contraste con el sistema de clasificación actual, ANA y AN no eran clínicamente distintos. Los resultados subrayan la necesidad de un acceso equitativo al tratamiento y una cobertura de seguro igual para los trastornos de la conducta alimentaria restrictivos en todo el espectro de peso.

Sex Differences in the Relationship between Chronotype and Eating Behaviour: A Focus on Binge Eating and Food Addiction.

BACKGROUND: Men are more likely than women to have subthreshold overeating disorders. Lifestyle plays a role as a determinant, while chronotype is an emerging factor. Chronotype explains the natural preferences of wakefulness and activity throughout the day: evening chronotypes (E-Types), those most productive in the evening, have been linked with unhealthy dietary patterns and a higher propensity to substance addiction than morning types (M-Types). METHODS: We carried out a cross-sectional study on 750 overweight or obese adults (70% females, 48 ± 10 years, BMI 31.7 ± 5.8 kg/m2). The Binge-Eating Scale, the Yale Food Addiction Scale 2.0 (YFAS 2.0), the reduced Morningness-Eveningness Questionnaire (rMEQ), and the MEDAS questionnaire were used to assess binge eating, food addiction, chronotype, and adherence to the Mediterranean diet, respectively. RESULTS: No differences in BES binge-eating and FA food-addiction scores occurred between chronotypes, but we found significant interactions between sex × rMEQ score. While women showed the same prevalence for binge eating and food addiction across all chronotypes, binge eating and food addiction risk increased with reducing rMEQ score in men, indicating that being male and E-Type increases the risk association of binge eating and/or food addiction prevalence. CONCLUSIONS: chronotype is associated with binge eating and food addiction in men, emphasizing the link between chronobiology and sex differences as determinants in appetite and eating behaviour dysregulation and in overweight and obesity.

Naltrexone/bupropion for binge-eating disorder: A randomized, double-blind, placebo-controlled trial.

OBJECTIVE: Binge-eating disorder (BED) is a prevalent psychiatric disorder associated with obesity. Few evidence-based treatments exist for BED, particularly pharmacological options. This study tested the efficacy of naltrexone/bupropion for BED. METHODS: A randomized, double-blind, placebo-controlled, 12-week trial tested naltrexone/bupropion for BED with and without obesity. Eighty-nine patients (70.8% women, 69.7% White, mean age 45.7 y, mean BMI 35.1 kg/m2 , 77.5% with BMI ≥ 30 kg/m2 ) were randomized to placebo (n = 46) or naltrexone/bupropion (n = 43), with randomization stratified by obesity status and gender; 92.1% completed post-treatment assessments. RESULTS: Mixed models of binge-eating frequency revealed significant reductions that did not differ significantly between naltrexone/bupropion and placebo. Logistic regression of binge-eating remission rates revealed that naltrexone/bupropion and placebo did not differ significantly. Obesity status did not predict, or moderate, binge-eating outcomes considered either continuously or categorically. Mixed models revealed that naltrexone/bupropion was associated with significantly greater percentage weight loss than placebo. Logistic regression revealed that naltrexone/bupropion had significantly higher rates of attaining ≥5% weight loss than placebo (27.9% vs. 6.5%). Obesity status did not predict or moderate weight-loss outcomes. CONCLUSIONS: Naltrexone/bupropion did not demonstrate effectiveness for reducing binge eating relative to placebo but showed effectiveness for weight reduction in patients with BED. Obesity status did not predict or moderate medication outcomes.

Binge-Eating Precursors in Children and Adolescents: Neurodevelopment, and the Potential Contribution of Ultra-Processed Foods.

Binge-eating disorder (BED) is a highly prevalent disorder. Subthreshold BED conditions (sBED) are even more frequent in youth, but their significance regarding BED etiology and long-term prognosis is unclear. A better understanding of brain findings associated with BED and sBED, in the context of critical periods for neurodevelopment, is relevant to answer such questions. The present narrative review starts from the knowledge of the development of emotional self-regulation in youth, and the brain circuits supporting emotion-regulation and eating behaviour. Next, neuroimaging studies with sBED and BED samples will be reviewed, and their brain-circuitry overlap will be examined. Deficits in inhibition control systems are observed to precede, and hyperactivity of reward regions to characterize, sBED, with overlapping findings in BED. The imbalance between reward/inhibition systems, and the implication of interoception/homeostatic processing brain systems should be further examined. Recent knowledge of the potential impact that the high consumption of ultra-processed foods in paediatric samples may have on these sBED/BED-associated brain systems is then discussed. There is a need to identify, early on, those sBED individuals at risk of developing BED at neurodevelopmental stages when there is a great possibility of prevention. However, more neuroimaging studies with sBED/BED pediatric samples are needed.

Weight-based discrimination and disordered eating behaviors in a cohort of U.S. sexual minority young adults.

OBJECTIVE: Though prevalent, weight-based discrimination is understudied and has been linked to disordered eating behaviors (DEB) among adolescents and adults. Sexual minority populations experience elevated risk of DEB, but little is known about the role of weight discrimination in this elevated risk. METHODS: Participants were 1257 sexual minority women and men (ages 18-31 years) in the US Growing Up Today Study cohort. We examined cross-sectional associations between weight discrimination victimization and three DEB in the past year: unhealthy weight control behaviors, overeating, and binge eating. Generalized estimating equations, adjusted for potential confounders, were used to estimate prevalence ratios (PRs) and 95% confidence intervals (CIs). RESULTS: Three in 10 participants (31%) reported weight-based discrimination victimization. Sexual minority young adults who reported weight-based discrimination had greater relative prevalence of unhealthy weight control behaviors (PR [95% CI]: 1.92 [1.35, 2.74]), overeating (3.15 [2.24, 4.44]), and binge eating (3.92 [2.51, 6.13]), compared with those who reported no weight-based discrimination. Associations with overeating and binge eating remained significant after adjusting for BMI. DISCUSSION: The role of weight-based discrimination, and its intersections with other forms of stressors for sexual minority young adults, must be included in efforts to advance eating disorder prevention for this underserved population. PUBLIC SIGNIFICANCE: Three in 10 sexual minority young adults in this study had experienced weight-based discrimination, a common but understudied form of discrimination. Sexual minority young adults who experienced weight-based discrimination were at greater risk of disordered eating behaviors than those who had not experienced weight-based discrimination. These findings suggest that weight-based discrimination may be an important-and preventable-risk factor for disordered eating behaviors among sexual minority young adults.

Anti-Diabetic Drugs Inhibit Bulimia Induced Obesity.

BACKGROUND: Obesity is primarily a consequence of food addiction. Drugs have been confirmed effective for weight loss more or less related to the functional connectivity in neural networks and metabolic patterns. Recent studies have shown that some anti-diabetic drugs, such as Metformin and Dapagliflozin have similar weight loss effects, however, their mechanisms are unclear. We hypothesized that the functional connectivity and energy metabolism might be associated with the mechanisms. METHODS: Male ob/ob mice were fed with high-fructose-fat-diet (HFFD) for 4 weeks to esteblish obesity model. Then mice were divided into normal saline (NS, as control), Metformin (Metformin, 50 mg/kg/day by gavage), and Dapagliflozin (Dapagliflozin, 10 mg/kg/day by gavage) groups. Functional connectivity amplitude of low-frequency signal fluctuations and regional cerebral blood volume (rCBV) quantification were statistically analyzed in the linear mixed model, meanwhile, metabolic pattern of intestinal cells (IECs) were also tested. RESULTS: Our results showed that Blood Oxygen on Level Depending (Bold) signaling responses, functional connectivity, and rCBV quantification tended to be attenuated in the Metformin group compared to the control and Dapagliflozin groups. While only Dapagliflozin prevented HFFD induced hyper survival of intestinal cells and hypertrophy of intestinal villus by reducing glycolysis levels. Both Metformin and Dapagliflozin are effective for weight loss. CONCLUSIONS: Our findings showed that Dapagliflozin and Metformin may inhibit bulimia induced obesity with different mechanisms. We speculate that Metformin may affect appetite regulation, while Dapagliflozin can affect the survival and metabolic patterns of intestinal cells, thus significantly affecting the absorption of nutrients. So, combining Metformin and Dapgliflozin may be more beneficial for clinical improvement in bulimia induced obesity.

Food insecurity and binge eating: A systematic review and meta-analysis.

OBJECTIVE: This review synthesized literature on the relationship between food insecurity and binge eating. METHODS: Relevant studies were identified by searching PubMed, CINAHL, PsycINFO, and gray literature from inception to October 2022. Eligible studies included primary research that assessed the relationship between food insecurity and binge eating. Data extraction was performed independently by two reviewers. Pooled odds ratios and 95% confidence intervals (CI) were obtained from random effect models with the R package meta. Analyses were stratified by binge eating versus binge-eating disorder (BED), study type (cross-sectional vs. longitudinal), and age (adults vs. adolescents). RESULTS: We included 24 articles that reported on 20 studies, and 13 articles were included in the meta-analysis. Based on the random effects meta-analysis, the odds of adults in the food insecure group having binge eating were 1.66 (95% CI = 1.42, 1.93) times the odds of adults in the food secure group having binge eating. The odds of adults in the food insecure group having BED were 2.70 (95% CI = 1.47, 4.96) times the odds of adults in the food secure group having BED. Insufficient data were available for a meta-analysis on adolescents or longitudinal relationships. CONCLUSIONS: These findings support that food insecurity is associated with binge eating in adults. There is a need for research to investigate the mechanisms underlying this relationship. Results highlight the importance of screening participants with food insecurity for disordered eating behaviors and vice versa. Future research is needed to examine whether interventions targeting food insecurity may help to mitigate disordered eating behaviors. PUBLIC SIGNIFICANCE: Food insecurity is a common but under-recognized contributor to binge eating. In this article, we systematically reviewed research that has been published on the relationship between food insecurity and binge eating. We found support that food insecurity should be considered in the prevention and treatment of binge eating.

OBJETIVO: Esta revisión sintetizó la literatura sobre la relación entre la inseguridad alimentaria y comer en atracones. MÉTODOS: Los estudios relevantes se identificaron mediante búsquedas en PubMed, CINAHL, PsycINFO y literatura gris desde su inicio hasta octubre de 2022. Los estudios elegibles incluyeron estudios primarios que evaluaron la relación entre la inseguridad alimentaria y los atracones. La extracción de datos fue realizada de forma independiente por 2 revisores. Los odds ratios agrupados y los intervalos de confianza (IC) del 95% se obtuvieron de modelos de efectos aleatorios con el paquete R meta. Los análisis se estratificaron por comer en atracones versus trastorno por atracón (TpA), tipo de estudio (transversal vs longitudinal) y edad (adultos vs adolescentes). RESULTADOS: Se incluyeron 24 artículos que informaron sobre 20 estudios y 13 artículos se incluyeron en el metaanálisis. Según el metaanálisis de efectos aleatorios, las probabilidades de que los adultos en el grupo de inseguridad alimentaria comieran en atracones fue de 1,66 (IC del 95% = 1,42, 1,93) veces las probabilidades de que los adultos en el grupo de seguridad alimentaria comieran en atracones. Las probabilidades de que los adultos en el grupo de inseguridad alimentaria tuvieran TpA fue 2.70 (IC del 95% = 1.47, 4.96) veces las probabilidades de que los adultos en el grupo de seguridad alimentaria tuvieran TpA. No hubo datos suficientes disponibles para un metaanálisis sobre adolescentes o relaciones longitudinales. CONCLUSIONES: Estos hallazgos apoyan que la inseguridad alimentaria está asociada con comer en atracones en adultos. Existe la necesidad de desarrollar investigación para investigar los mecanismos subyacentes a esta relación. Los resultados resaltan la importancia de evaluar a los participantes con inseguridad alimentaria para detectar conductas alimentarias disfuncionales y viceversa. Se necesitan estudios de investigación futuros para examinar si las intervenciones dirigidas a la inseguridad alimentaria pueden ayudar a mitigar los comportamientos alimentarios disfuncionales.

Predictors and significance of rapid response to behaviorally based treatment of binge eating disorder.

OBJECTIVE: This study examined baseline predictors of rapid response and its prognostic significance in a clinical trial of behaviorally based weight loss treatment (BBWLT) for binge eating disorder in patients with obesity. METHODS: One hundred ninety-one participants receiving BBWLT were assessed at baseline, throughout treatment, and at posttreatment (6 months) by independent assessors. Rapid response was defined as ≥ 65% reduction in binge eating by the fourth treatment week. Patients with versus without rapid response were compared on demographic features, a broad range of current/past clinical and psychiatric variables, and treatment attitudes. Rapid response was used to prospectively predict posttreatment outcomes. RESULTS: Rapid response, which characterized 63% (N = 120) of participants, was not associated significantly with any demographic features or with any current/past clinical and psychiatric variables. Higher ratings (at week one) regarding the logic of BBWLT and greater confidence that treatment would help with binge eating and weight loss were associated significantly with rapid response (at week four). Rapid response was prospectively associated with significantly better binge eating and weight loss outcomes. CONCLUSIONS: These findings indicate that rapid response to BBWLT for binge eating disorder prospectively predicts superior clinical outcomes in both binge eating and weight loss. Treatment attitudes, rather than patient demographic or clinical severity variables, are prospectively associated with rapid response.

The interplay between emotion regulation, interpersonal problems and eating symptoms in individuals with obesity: A network analysis study.

INTRODUCTION: A complex and bidirectional relationship between eating and psychological symptoms in individuals with obesity has been proposed. This study aims to identify the specific processes playing a role in this association, using a data-driven approach. METHODS: Two hundred ninety-four adults with obesity, including 106 (36 %) with binge-eating disorder, were consecutively admitted to a specialized public center. They completed self-report questionnaires to assess emotion regulation, interpersonal problems, self-esteem, binge-eating symptoms, and expectancies regarding eating behaviors. To assess the interplay among eating and psychological variables, a network analysis was used. The bridge function analysis was also performed to identify the bridge nodes among three communities (eating symptoms, interpersonal and emotional problems). RESULTS: The network was stable. Limited access to emotion regulation strategies, eating helps manage negative affect, and non-assertiveness were the nodes with the highest strength centrality. Lack of emotional clarity, non-assertiveness, socially inhibition, and binge-eating were the nodes with the highest bridge strength. LIMITATIONS: The main limitation of the study is the cross-sectional nature of the findings which prevents to infer causality regarding the association between symptoms in the network. DISCUSSION: An interplay between eating symptoms and affective and interpersonal factors characterizes individuals with obesity. Across the variety of psychological problems associated with obesity, the present study suggests specific psychological variables and their connections that could be addressed to improve treatment outcome.

Associations Between Attention Deficit Hyperactivity Disorder Symptom Dimensions and Disordered Eating Symptoms in Adolescence: A Population-Based Twin Study.

Although bivariate associations between attention-deficit/hyperactivity disorder (ADHD) and eating disorders in adolescent girls and boys have been previously identified, the mechanistic link underlying the symptom-level associations remains unclear. We evaluated shared genetic and environmental influences on ADHD symptoms and disordered eating in 819 female and 756 male twins from the Swedish TCHAD cohort using bivariate models. Common additive genetic and unique environmental effects accounted for majority of ADHD and disordered eating associations in a differential manner. For girls, the strongest genetic correlation was observed for cognitive/inattention problems-bulimia (0.54), with genetic factors accounting for 67% of the phenotypic correlation. For boys, the strongest genetic correlations were observed for conduct problems-bulimia and hyperactivity-bulimia (~ 0.54), accounting for 83% and 95% of the phenotypic correlation, respectively. As per our findings, the risk of comorbidity and shared genetics highlights the need for preventative measures and specialized treatment for ADHD and disordered eating in both sexes.

Eating Habits and Eating Disorder Associated Behavior in Bipolar Disorder.

ABSTRACT: A relevant comorbidity of bipolar disorder (BD) is eating disorders (EDs). Crossed vulnerability factors as eating disorder-specific symptoms (EDSSs) may trigger the onset of both disorders in either direction. The Structured Inventory for Anorexic and Bulimic Eating Disorders for Self-Report was used to examine the occurrence of EDs in euthymic/subsyndromal individuals with BD ( n = 86) and healthy controls ( n = 86) matched for age and sex. Furthermore, we explored EDSSs with the subscales "general psychopathology and social integration," "bulimic symptoms," "body image and slimness ideal," "sexuality and body weight," "counteract," and "atypical binge." Higher rates of all EDSSs were reported in BD. Younger individuals with BD showed higher expression in "bulimic symptoms," "body image and slimness ideal," and "atypical binge" subscales. No participants fulfilled ED diagnosis. The findings show a link between EDSS and BD. Clinicians should pay attention to a multimodal intervention, considering risk factors, investigating eating habits and ED associated behaviors.

Bi-directional associations between depressive symptoms and eating disorder symptoms in early adolescence.

Despite frequently co-occurring, the temporal relationship between depression and eating disorder symptoms remains poorly understood. This exploratory study sought to investigate the reciprocal relationship between depressive symptoms and (1) shape and weight dissatisfaction, (2) shape and weight overvaluation, (3) preoccupation with shape or weight, (4) preoccupation with food, (5) dietary restraint and (6) binge eating in early adolescence. Adolescents (N = 1393) aged between 11.4 and 13.9 years (M = 12.50, SD = 0.38) completed the Centre for Epidemiological Depression Scale-Revised and Eating Disorder Examination Questionnaire-Adolescent version at the beginning of secondary school (T1) and 12-months later (T2). Cross-lagged models were created to assess the reciprocal relationship between depressive symptoms and ED symptoms. Depressive symptoms at T1 predicted shape and weight dissatisfaction, shape and weight overvaluation, preoccupation with shape or weight, preoccupation with food, dietary restraint and binge eating at T2. Shape and weight dissatisfaction and binge eating were the only ED symptoms at T1 to predict depressive symptoms at T2. Findings suggest young adolescents who experience depressive symptoms in their first year of secondary school are at-risk of developing ED symptoms over the subsequent 12-month period.

The impact of discrimination on binge eating in a nationally representative sample of Latine individuals.

OBJECTIVE: Latines have higher rates of eating disorders characterized by binge eating compared to their non-Latine white counterparts, yet culturally and socially relevant factors related to binge eating in Latines have been largely understudied. The purpose of the current study was to examine how discrimination and acculturative stress were associated with binge eating in a nationally representative sample of Latines. An additional aim was to test the extent to which family cohesion and social support could buffer against the effects of discrimination and acculturative stress on binge eating. METHOD: Participants (56% female, N = 2550) were Latines enrolled in the National Latino and Asian American Study. Structural equation modeling using 1000 re-sampled data sets built from machine learning iterative sampling procedures was used to examine the effects of discrimination, acculturative stress, family cohesion, and social support on binge eating. RESULTS: Results indicated that only discrimination was significantly associated with binge eating. Neither the direct effect of acculturative stress, interaction of family cohesion and acculturative stress, interaction of social cohesion and acculturative stress, nor the interaction of social support and discrimination were significantly associated with binge eating. DISCUSSION: This study highlights the need for mental-health providers to understand and assess discrimination among Latines presenting with concerns of binge eating. Treatments that effectively provide coping strategies to manage discriminatory experiences and reduce binge eating could improve both effectiveness of treatment and retention rates for Latine individuals with binge eating. PUBLIC SIGNIFICANCE: This study examined the association of discrimination, acculturative stress, family cohesion, and social support with binge eating in Latines. Only discrimination was significantly associated with binge eating, highlighting the importance for providers to assess discrimination among Latines with binge-eating concerns and to improve equity, inclusion, and belonging at a societal level. Modifying existing treatments to address coping with discrimination could improve the effectiveness for Latines with binge-eating concerns.

Overvaluation of Shape and Weight (Not BMI) Associated with Depressive Symptoms and Binge Eating Symptoms Pre- and Post-bariatric Surgery.

PURPOSE: Overvaluation of shape and weight (OSW) involves defining self-worth by body shape/weight. Among persons seeking bariatric surgery, cross-sectional studies have found associations between OSW, depressive symptoms, and disordered eating. MATERIALS AND METHODS: Relationships among OSW, depressive symptoms, binge eating symptoms, and BMI were analyzed both cross-sectionally and over time among 145 adults who had bariatric surgery. Participants completed the following measures pre-surgery and 1.5 to 3 years post-surgery: Eating Disorder Examination Questionnaire (EDE-Q), Binge Eating Scale, Patient Health Questionnaire, and body weight and height. OSW was measured by averaging two items on the EDE-Q which ask participants to rate how much their weight/shape influences how they judge themselves as a person. Analyses included Wilcoxon signed-ranks, bootstrapped Pearson correlations, and bootstrapped hierarchical linear regressions. RESULTS: OSW was significantly associated with depressive symptoms and binge eating symptoms both pre- and post-surgery, but was not associated with BMI at either timepoint. Improvements in OSW were associated with concurrent changes in depression and binge eating; reductions in BMI were not significantly associated with changes in any of these variables. CONCLUSIONS: Findings suggest that self-evaluation is more important in regard to changes in depressive and binge eating symptoms than is BMI (and vice versa), and support the importance of assessing and treating psychological considerations among persons seeking bariatric surgery.

Longitudinal patterns of comorbidity between anxiety, depression and binge eating symptoms among patients with obesity: A path analysis.

BACKGROUND: Depression, anxiety, and binge eating are common psychiatric symptoms among people with obesity. Although many studies seek to understand the mechanisms of association between these psychiatric symptoms, there is no still consensus about the longitudinal association. METHODS: 155 patients (124 women) were recruited from a university-based bariatric center and evaluated over three waves (T0-T1-T2). In the last period the sample comprised 126 (104 women) participants. Trained clinicians assessed psychiatric symptoms by telephone interview using measurement scales. Partial Least Squares (PLS) was applied to investigate the path effects between anxiety, depression and binge eating symptoms over time. RESULTS: The results of path coefficients (ß) showed that the effect of anxiety on depression was constantly significant in all periods T0 (ß = 0.74), T1 (ß = 0.71), and T2 (ß = 0.67). Anxiety had an effect on binge eating in T0 (ß = 0.39) and T2 (ß = 0.26) but not in T1. Binge eating affected depressive symptoms only in T2 (ß = 0.22). Two carry-over-effects were significant binge eating in T0-T1 (ß = 0.41) and T1-T2 (ß = 0.19). LIMITATIONS: Telephone interviews, social isolation due to the pandemic and the social desirability may have contributed to collection and information biases. CONCLUSION: Anxiety has significant path effects on depression and binge eating. Binge eating was shown to be the most unstable symptom over time. The time factor seems to contribute to path effects between the psychiatric symptoms. The results draw attention to the fact that psychiatric symptoms must be evaluated and treated in association with each other, and investigated over time.

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.
