RESUMO

The contribution of an addictive process to anorexia nervosa (AN) is an area of growing interest. Yet, little is known about how the food addiction concept (FA) may be of interest in understanding AN. This study investigates prevalence of FA diagnostic and its association with markers of severity in individuals with AN. We conducted a retrospective study in a sample of 73 patients with AN. We assessed FA with the Yale Food Addiction Scale 2.0, depressive and anxiety disorders, impulsivity (Beck Depression Inventory, STAI, BIS-11) and eating behavior (BITE, EDE-Q). Prevalence of FA in our sample was 47%. FA was significantly associated and positively correlated with the binge-eating/purging subtype of AN, higher levels of depression, anxiety and greater eating psychopathology. FA was not associated with level of impulsivity nor leptin and IGF-1 blood levels. The relationship between FA severity and AN severity was mediated by the severity of binge eating behaviors. Our results suggest that the presence of FA may represent a more severe variant of AN. Longitudinal studies are needed to better understand the etiologic process between FA and AN.

RESUMO

The objective of this study is to assess the effect of alcohol consumption, anxiety, and food restriction before and after consuming alcohol and body image on the risk of anorexia and bulimia in college students from Tijuana, Baja California, through predictive statistical models. A quantitative, descriptive, and cross-sectional design and a non-probabilistic sample of 526 college students from Tijuana, Baja California, México were used. Application of the scales (with acceptable psychometric properties) was conducted in classrooms. Through path analyses, four models were found with adequate indicators of goodness of fit: (1) risk of anorexia in women [Chi Square (X2) = 5.34, p = 0.376, Adjusted Determination Coefficient (R2)= 0.250]; (2) anorexia risk for men (X2 = 13.067, p = 0.192, R2 = 0.058); (3) risk of bulimia in women (X2 = 3.358, p = 0.645, R2 = 0.202); and bulimia risk for men (X2 = 14.256, p = 0.075, R2 = 0.284). The findings provide empirical evidence for the food and alcohol disturbance model.

RESUMO

This study compared women with binge eating disorders or bulimia nervosa with and without night eating syndrome regarding childhood maltreatment and psychopathology relative to healthy controls. The 426 participants (aged 18-60) were divided into two groups: eating disorders (n = 158) and healthy controls (n = 268). Eating disorders was divided into bulimia nervosa, binge eating disorder, and night eating syndrome with binge eating. Participants completed questionnaires: childhood trauma, eating disorders, self-esteem, and psychopathology. No significant differences were found for most variables in the eating disorders subgroups except physical neglect, which was more prevalent in night eating syndrome with binge eating. All variables differed significantly between eating disorders and healthy controls. Significant correlations emerged between childhood maltreatment, psychopathology, emotional abuse, and self-esteem in eating disorders. Regression showed that emotional abuse significantly predicted self-esteem in eating disorders, and group significantly moderated the effect of emotional abuse on psychopathology. Results emphasize that in this specific sample and variables, night eating syndrome with binge eating may be a variant of binge eating disorder or bulimia nervosa and not a separate diagnostic entity. The results highlight the importance of early assessment of childhood maltreatment, particularly emotional abuse, in patients with night eating syndrome.

RESUMO

Objective To evaluate aspects of eating behavior, presence of non-food substance consumption and negative urgency in women from an on-line support group for eating disorders. Methods Participants (n=147) completed questionnaires for binge eating assessment, Intuitive Eating, negative urgency, cognitive restraint and a question of non-food substance consumption. Participants were separated according to criteria for bulimic symptoms and compulsive symptoms. Results The consumption of non-food substances was 4.8% (n=7). The Bulimic Group (n=61) showed higher values for binge eating (p=0.01), cognitive restraint (p=0.01) and negative urgency (p=0.01) compared with the Compulsive Group (n=86). Only the Compulsive Group showed an inverse correlation between scores for binge eating and Intuitive Eating (p=0.01). In both groups, binge eating was inversely correlated with the subscale of body-food choice congruence of Intuitive Eating scale. As expected, the Bulimic Group reached higher values for measures of disordered behaviors such as cognitive restraint and binge eating, and lower scores for Intuitive Eating. Conclusion The aspects of Intuitive Eating are inversely associated with compulsive and bulimic symptoms and the correlation analyses for binge eating and negative urgency agreed with models reported in published literature about negative urgency.

RESUMO

Binge-eating disorder is the most common eating disorder. Various neuropeptides play important roles in the regulation of feeding behavior, including relaxin-3 (RLN3), which stimulates food intake in rats through the activation of the relaxin-family peptide-3 receptor (RXFP3). Here we demonstrate that a likely mechanism underlying the orexigenic action of RLN3 is RXFP3-mediated inhibition of oxytocin- and arginine-vasopressin-synthesizing paraventricular nucleus (PVN) magnocellular neurosecretory cells. Moreover, we reveal that, in male and female rats, this action depends on M-like potassium conductance. Notably, higher intra- and peri-PVN RLN3 fiber densities were observed in females, which may constitute an anatomic substrate for observed sex differences in binge-eating disorder. Finally, in a model of binge-eating in female rats, RXFP3 blockade within the PVN prevented binge-eating behavior. These data demonstrate a direct RLN3/RXFP3 action in the PVN of male and female rats, identify the associated ionic mechanisms, and reveal that hypothalamic RLN3/RXFP3 signaling regulates binge-eating behavior.SIGNIFICANCE STATEMENT Binge-eating disorder is the most common eating disorder worldwide, affecting women twice as frequently as men. Various neuropeptides play important roles in the regulation of feeding behavior, including relaxin-3, which acts via the relaxin-family peptide-3 receptor (RXFP3). Using a model of binge-eating, we demonstrated that relaxin-3/RXFP3 signaling in the hypothalamic paraventricular nucleus (PVN) is necessary for the expression of binge-eating behavior in female rats. Moreover, we elucidated the neuronal mechanism of RLN3/RXFP3 signaling in PVN in male and female rats and characterized sex differences in the RLN3 innervation of the PVN. These findings increase our understanding of the brain circuits and neurotransmitters involved in binge-eating disorder pathology and identify RXFP3 as a therapeutic target for binge-like eating disorders.

RESUMO

BACKGROUND: The Binge Eating Genetics Initiative (BEGIN) is a multipronged investigation examining the interplay of genomic, gut microbiota, and behavioral factors in bulimia nervosa and binge-eating disorder. METHODS: 1000 individuals who meet current diagnostic criteria for bulimia nervosa or binge-eating disorder are being recruited to collect saliva samples for genotyping, fecal sampling for microbiota characterization, and recording of 30 days of passive data and behavioral phenotyping related to eating disorders using the app Recovery Record adapted for the Apple Watch. DISCUSSION: BEGIN examines the interplay of genomic, gut microbiota, and behavioral factors to explore etiology and develop predictors of risk, course of illness, and response to treatment in bulimia nervosa and binge-eating disorder. We will optimize the richness and longitudinal structure of deep passive and active phenotypic data to lay the foundation for a personalized precision medicine approach enabling just-in-time interventions that will allow individuals to disrupt eating disorder behaviors in real time before they occur. TRIAL REGISTRATION: The ClinicalTrials.gov identifier is NCT04162574. November 14, 2019, Retrospectively Registered.

RESUMO

OBJECTIVES: This project examined risk factors of disordered eating in athletes by adapting and applying a theoretical model. It tested a previously proposed theoretical model and explored the utility of a newly formed model within an athletic population across gender, age, and sport type to explain disordered eating. DESIGN: The design was cross-sectional and the first phase in a series of longitudinal studies. METHODS: 1,017 athletes completed online questionnaires related to social pressures, internalisation, body dissatisfaction, negative affect, restriction, and bulimia. Structural equation modelling was employed to analyse the fit of the measurement and structural models and to do invariance testing. RESULTS: The original theoretical model failed to achieve acceptable goodness of fit (χ2 [70, 1017] = 1043.07; p < .0001. CFI = .55; GFI = .88; NFI = .53; RMSEA = .12 [90% CI = .111-.123]). Removal of non-significant pathways and addition of social media resulted in the model achieving a parsimonious goodness of fit (χ2 [19, 1017] = 77.58; p < .0001. CFI = .96; GFI = .98; NFI = .95; RMSEA = .055 [90% CI = .043-.068]). Invariance tests revealed that the newly revised model differed across gender, age, level, competition status, and length of sport participation. CONCLUSION: This study showed that the formation of disordered eating symptomology might not be associated with sport pressures experienced by athletes. It revealed that disordered eating development varies across gender, competition level, sport type, and age, which must be considered to prevent and treat disordered eating in athletes.

RESUMO

It has been hypothesized that leptin level alterations in Eating Disorders (EDs) represent a maintaining factor for pathological reward-related ED behaviors, given leptin role in the dopaminergic reward systems. The aim of the present study was to evaluate the role of leptin in EDs as a mediator for the relationship between Body Mass Index (BMI) and several pathological behaviors, such as dietary restraint, compensatory exercise, vomiting, binge eating and emotional eating. Sixty-two patients with EDs and 41 healthy controls (HC) had their blood drawn and completed psychometric tests for the evaluation of general psychopathology, ED psychopathology and emotional eating. Moderated linear regression models showed that, in the presence of high levels of ED psychopathology, leptin levels were negatively associated with dietary restraint and compensatory exercise, and positively with emotional eating and binge eating. Finally, leptin showed an indirect effect on the association between BMI and all these reward-related behaviors. These results suggest that a variation of BMI maintains these pathological ED behaviors through a variation in leptin levels. Considering the role of leptin in reward circuits, the results seem to confirm an aberrant food-related reward mechanism in ED patients.

RESUMO

PURPOSE: The aim of the study was to quantify the association between perceived everyday discrimination and binge eating among Latinas in the United States. METHODS: Participants included 1014 Latinas from the 2002-2003 National Latino and Asian American Study. Modified Poisson models with robust standard errors were used to estimate sociodemographic-adjusted prevalence ratios (aPRs) and 95% confidence intervals (CIs) of binge eating associated with overall and attribution-specific discrimination. RESULTS: Approximately 7% of Latinas reported binge eating. Increased frequency of discrimination was associated with a higher prevalence of binge eating (aPR, 1.59; 95% CI, 1.23-2.06), and Latinas reporting frequencies of discrimination in the top tertile had the greatest prevalence elevation (aPR, 3.63; 95% CI, 1.32-10.00). There were important differences by discrimination attribution: Latinas experiencing primarily height/weight-based or skin color-based discrimination had the greatest prevalence elevation relative to those reporting no discrimination (aPR, 10.24; 95% CI, 2.95-35.51; and aPR, 8.83; 95% CI, 2.08-37.54, respectively), whereas Latinas reporting primarily race-based discrimination had the lowest prevalence elevation (aPR, 1.64; 95% CI, 0.47-5.69). CONCLUSIONS: Discrimination may be an important social determinant of Latinas' binge eating. Future research should incorporate expanded conceptual models that account for Latinas' complex social environment, focusing on intersecting dimensions of identity.

RESUMO

OBJECTIVES: This study investigated the utility of DSM-5 indicators of loss of control (LOC) eating in adult bariatric surgery patients who presented with binge-eating episodes. METHODS: Participants (all women) were 40 preoperative and 28 postoperative bariatric surgery patients reporting objective binge eating (OBE), 46 preoperative and 52 postoperative with subjective binge-eating (SBE), 53 bulimia nervosa (BN) controls, and 34 binge-eating disorder (BED) controls. Face-to-face Eating Disorder Examination interviews and questionnaires were administered. ANOVA, T-test, χ 2 , and regressions compared the groups in terms of LOC indicators endorsed and to explain disordered eating psychopathology. RESULTS: The indicator most commonly reported by bariatric patients with OBE was "feeling disgusted" (90% and 75% of pre- and postoperative groups), and the least endorsed was "eating alone" (40 and 28.6%). These indicators were reported by >84.9% of the BN and BED. Bariatric patients (pre- or post-surgery) with OBE only reported a higher number of indicators than patients with SBE only (t(150) = 2.34, p = .021). A higher number of indicators reported were associated with increased eating-related psychopathology (F(1,134) = 31.06, p < .001), but only for the post-surgery patients. CONCLUSIONS: The LOC indicators proposed by DSM-5 need to be refined or revised for the bariatric population. Highlights Bariatric patients endorse fewer LOC indicators than BN or BED during a binge-eating episode. Some of the DSM-5 LOC indicators may not be suited to assess episodes of loss of control eating among bariatric patients. The Higher the number of LOC indicators reported, the higher the eating-related psychopathology.

RESUMO

Binge eating disorder (BED) as well as individual subthreshold binge eating symptoms are related to deleterious physical and socioemotional outcomes among adolescents. The present study examined the prevalence of specific binge eating behaviors among a sample of primarily non-Hispanic Black outpatients presenting to weight management and endocrinology clinics. Analyses are based on 103 adolescents (69.9% female, 66.9% non-Hispanic Black) who endorsed one or more binge eating symptoms on a nonstandardized clinical assessment patterned after Diagnostic Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria. The most commonly endorsed symptom was eating in excess of what is considered normal (71.8%), while least commonly endorsed symptoms included guilt, distress, and embarrassment due to overeating (17.5% to 26.2%). More than half of the participants endorsed multiple specific binge eating symptoms. The level of subthreshold symptomatology reported underscores the importance of developmental and cultural tailoring of prevention and intervention efforts to address these behaviors as a means of curbing clinical-level onset of BED.

RESUMO

AIM: The study was aimed at studying binge eating behavior in urban adolescents. This was in keeping with the increasing prevalence of obesity and lifestyle disorders amongst Indian population especially in adolescent groups. METHODS: 2000 adolescents English speaking schools in Mumbai were administered the Binge Eating Scale and the Eating Behaviors and Pattern Questionnaire after assent and parental consent. The prevalence of Binge eating behavior was estimated along with the socio-demographic data and other data from scale which was analyzed using the Chi square test and ANOVA where appropriate. RESULTS: The mean age of the total sample was 15.05 ± 1.65 years. Females reported higher Binge eating behavior than males and majority of the sample belonging to upper and lower middle- class families reported high binge eating behavior. The prevalence of Binge eating behavior was high with 1002 (50.1 %) adolescents reporting moderate binge eating while 736 (36.8 %) reporting severe binge eating. Significantly greater adolescents in the binge eating group reported irregular menses and being overweight and obese. There was a significantly greater proportion of adolescents in the binge eating group that ate out weekly and ate more fried food. CONCLUSION: There is an increasing trend of obesity and lifestyle disorders in adolescent population that can be linked to Binge eating behavior however, the role of binge eating in context of one of the potential cause of lifestyle disorders and obesity has not been studied in Indian adolescents despite the prevalence of Binge eating and overweight being high in this population, we need further larger studies to corroborate the findings of this study.

RESUMO

INTRODUCCIÓN: las personas con obesidad suelen ser objeto de estigmas asociados al peso por parte de la población. Los estudiantes del área de la salud, al formar parte de la sociedad, también experimentan actitudes antiobesidad, lo que puede afectar a la calidad de la atención que ofrecen. OBJETIVOS: analizar las diferencias por sexo, en estudiantes universitarios vinculados al área de la salud, con respecto a las actitudes antiobesidad, la obsesión por la delgadez, la bulimia y la insatisfacción corporal, identificando las variables que permitan predecir las actitudes negativas respecto a la obesidad. Además, se exploraron los significados asociados a la malnutrición por exceso. MÉTODO: con un diseño no experimental transversal y un muestreo no probabilístico por conveniencia, se accedió a 212 participantes. Los instrumentos fueron: AFA, EDI-2 y redes semánticas naturales. RESULTADOS: las mujeres presentaron valores más altos que los hombres en todas las variables estudiadas (p < 0,05), excepto en la bulimia (p > 0,05). La obsesión por la delgadez fue el único predictor de las actitudes antiobesidad (R2 = 0,40). Los significados más prevalentes hacia las personas con obesidad fueron "enfermedad" y "aspectos psicológicos". CONCLUSIONES: la presencia de obsesión por la delgadez en estudiantes que trabajarán en el abordaje integral de la obesidad es un predisponente a experimentar actitudes antiobesidad. Dentro de los significados asociados al sobrepeso más prevalentes en este grupo están los aspectos psicológicos, antes que los conceptos relacionados con la alimentación y la actividad física. Todo esto puede tener un impacto negativo en la calidad de la atención que ofrezcan


INTRODUCTION: people with obesity are often subjected to weight-related stigma by the population. Career students linked to the approach to obesity, as part of society, also experience anti-obesity attitudes, which can affect the quality of care they will offer. OBJECTIVES: to analyze the differences by sex, in university students linked to the health area, in anti-obesity attitudes, drive for thinness, bulimia, and body dissatisfaction, identifying variables allowing to predict negative attitudes regarding obesity. In addition, the meanings associated with excess malnutrition were explored. METHOD: with a cross-sectional, non-experimental design and non-probabilistic, convenience sampling 212 participants were accessed. Instruments included: AFA, EDI-2, and natural semantic networks. RESULTS: women showed higher values than men in all the variables studied (p < 0.05) except bulimia (p > 0.05). Drive for thinness was the only predictor for anti-obesity attitudes (R2 = 0.40). The most prevalent meanings attached to people with obesity were "illness" and "psychological issues". CONCLUSIONS: the presence of drive for thinness in students who will work in the comprehensive approach to obesity is a predisposing factor to experiencing anti-obesity attitudes. Among the most prevalent meanings associated with overweight in this group are psychological issues, rather than concepts related to food and physical activity. All this can have a negative impact on the quality of the care they offer

RESUMO

OBJECTIVE: Impulsivity and difficulties in regulating emotions are considered to be transdiagnostic characteristics of patients with eating disorders (EDs). The study aimed to investigate trait impulsivity and inhibitory components of impulsivity, related or unrelated to emotions in patients with EDs. METHOD: A total of 17 patients with anorexia nervosa (AN), 16 patients with bulimic-spectrum EDs (BSD) and 20 healthy control (HC) participants completed an impulsivity scale (UPPS-P) before performing an emotional inhibitory control task during electroencephalography (EEG) acquisition. RESULTS: Higher trait impulsivity in EDs than HC (with higher scores among BSD patients) was observed. However, no differences in behavioural measures or neural indexes [event-related potential (ERP)] of emotional and non-emotional inhibitory control were observed between patients and HC. CONCLUSION: The present results highlighted negative urgency, an impulsive personality trait related to emotions, as a common feature of AN and BSD. Lack of perseverance, a trait which is less related to emotions, specifically characterises patients with BSD. On the other hand, behavioural and ERP data did not show altered inhibitory control in EDs, for either general or emotional-related response inhibition.

RESUMO

The growing number of women, who are characterized by restrictive and bulimic behaviours towards their own body is observed especially in countries influenced by Westernalization. However, there is a lack of cross-cultural studies in this area. The main aim of the present study was to examine the psychological and socio-cultural risk factors for eating disorders in Polish and Japanese women. A cross-sectional research study was conducted among 18- to 29-year old Polish (n = 89) and Japanese (n = 97) women. The variables were measured using the Sociocultural Attitudes Towards Appearance Scale SATAQ-3, and the Eating Disorders Inventory EDI-3. The descriptive and comparative statistics, Spearman's rho, and the stepwise regression analysis were used. The global internalization of socio-cultural standards of body image proved to be a significant predictor of Body Dissatisfaction among Polish and Japanese women. The main analysis showed a significant relation between the Drive for Thinness and Interoceptive Deficits in the group of Japanese women, as well as a correlation between Drive for Thinness and Asceticism in the group of Polish women. The obtained results could improve the prevention aimed the dysfunctional eating behaviours. However, the cultural nuances need to be considered in understanding the risk factors for eating disorders.

RESUMO

Negative urgency (NU: tendency to act rashly when distressed) is the facet of impulsive personality that has been most predictive of binge eating, but less is known about the relative role of positive urgency (PU: tendency to act rashly in response to positive emotions). In addition, most studies have exclusively focused on women and the examination of pathological eating outcomes, using a dimensional symptom approach, has been somewhat limited. This study aimed to replicate and extend upon prior work. We examined the extent to which NU and/or PU are uniquely associated with dysregulated eating, using a latent factor comprised of dimensional symptoms, and directly tested whether effects differ by sex. Two independent cross-sectional samples of women and men were used (Sample 1: Midwestern university, 437 females, 348 males; Sample 2: Southwestern university, 301 females, 236 males). NU and PU were assessed with the UPPS-P Impulsive Behavior Scale, and dysregulated eating symptoms (i.e., binge eating, loss of control eating, eating concerns) were assessed with well-validated self-report questionnaires. Although both NU and PU showed significant positive associations with dysregulated eating, NU showed the strongest unique relationship with dysregulated eating in both samples. The relative role of PU was weakened in Sample 1 and completely attenuated in Sample 2 once its shared variance with NU was accounted for. All results were similar in men and women. Overall, findings continue to suggest that NU is the form of impulsivity that is most relevant to dysregulated eating in both men and women.

RESUMO

Affect regulation models of eating disorder behavior, which predict worsening of affect prior to binge-eating episodes and improvement in affect following such episodes, have received support in anorexia nervosa and bulimia nervosa. However, limited work has examined the trajectories of affect surrounding binge eating in binge-eating disorder (BED). In the current study, ecological momentary assessment data from 112 men and women with BED were used to examine the trajectories of positive affect (PA), negative affect (NA), guilt, fear, hostility, and sadness relative to binge-eating episodes. Prior to binge episodes, PA significantly decreased, whereas NA and guilt significantly increased. Following binge episodes, levels of NA and guilt significantly decreased and PA stabilized. Overall, results indicate improvements in affect following binge-eating episodes, suggesting that binge eating may function to alleviate unpleasant emotional experiences among individuals with BED, which is consistent with affect regulation models of eating pathology. Because improvements in negative affect were primarily driven by change in guilt, findings also highlight the relative importance of understanding the relationship between guilt and binge-eating behavior within this population.

RESUMO

Unhealthy diet and alcohol are serious health problems, especially in adolescents and young adults. "Binge" is defined as the excessive and uncontrolled consumption of food (binge eating) and alcohol (binge drinking). Both behaviors are frequent among young people and have a highly negative impact on health and quality of life. Several studies have explored the causes and risk factors of both behaviors, and the evidence concludes that there is a relationship between the two behaviors. In addition, some research postulates that binge eating is a precipitating factor in the onset and escalation of excessive alcohol consumption, while other studies suggest that alcohol consumption leads to excessive and uncontrollable food consumption. Given that no review has yet been published regarding the directionality between the two behaviors, we have set out to provide an upto- date overview of binge eating and binge drinking problems, analyzing their commonalities and differences, and their uni- and bidirectional associations. In addition, we explore the reasons why young people tend to engage in both behaviors and consider directions for future research and clinical implications.

RESUMO

The purpose of the study was to investigate the relationship between mindful eating, disordered eating and mood in university students in health-related disciplines. A total of 221 university students participated in the study; 102 students studied sport and exercise science (SS), 54 students pharmacy sciences (PS), and 65 students health sciences (HS). Participants completed the Binge Eating Scale (BES), the Mindful Eating Questionnaire (MEQ), and the Profile of Mood State questionnaire (POMS). 41% of the students were classified as binge eaters and 57% were above the POMS threshold of depression. Binge eaters were found to have significantly lower MEQ score and significantly higher total mood disturbance scores (TMD) compared to non-binge eaters (p < 0.01). Students with a high depression score exhibited no differences in the MEQ score but a significantly higher BES score compared to non-depressed students (p < 0.01). Gender differences were found in the MEQ with females exhibiting significantly higher scores in the MEQ score and in all MEQ subscales compared to males, with the exception of the emotional subscale that females were noted to have a lower score compared to males (p < 0.01). The MEQ score was inversely related to the BES score (r = -0.30, p < 0.01) and TMD (r = -0.21, p < 0.05). The MEQ score was a significant negative predictor of the variance of the binge eating behavior of the students (B = -3.17, p < 0.001). In conclusion, mindfulness in eating is inversely related to the binge eating behavior and mood state of university students studying health-related subjects and is a significant negative predictor of disordered eating behavior in this high risk population.
