The acceptability, feasibility, and preliminary efficacy of a supported online self-help treatment program for binge-eating disorder.

Studies in transdiagnostic eating disorder (ED) samples suggest supported online self-help programs (eTherapies) are effective and may improve access to treatment; however, their evaluation in those with binge-eating disorder (BED) is limited. Given BED's high prevalence and low levels of treatment uptake, further eTherapy evaluation is needed to broaden access to effective, evidence-based treatment options. The aim of this study was to investigate the acceptability, feasibility, and preliminary efficacy of a supported eTherapy for those with BED or subthreshold BED, and to examine symptom change across the duration of therapy. Nineteen women with BED completed a supported, 10-session Cognitive Behavioural Therapy-based eTherapy in an uncontrolled, pre-post, and 3 months follow up intervention study. Key outcomes were assessed by the Eating Disorder Examination Questionnaire (EDE-Q): objective binge episode (OBE) frequency and ED psychopathology. Feasibility was evaluated via program adherence and dropout, whilst acceptability was assessed through participant feedback post-treatment. Weekly symptom change (ED psychopathology) during treatment was assessed by the Eating Disorder Examination - Questionnaire Short (EDE-QS). Generalised estimating equations showed statistically and clinically significant reductions in OBEs and ED psychopathology (large effects) post-treatment, with these decreases maintained at follow up. Across weekly assessment, a marked slowing in the rate of change in ED psychopathology was observed after four sessions of the program. Program feasibility was high (i.e., 84% of content completed), as was program acceptability (i.e., 93% of participants expressed high levels of satisfaction). These results support the acceptability, feasibility, and preliminary efficacy of a supported eTherapy program for those with BED and suggest the variability of symptom change across the duration of therapy. Future research should further investigate findings in an adequately powered randomised controlled trial.

Effect of nivasorexant (ACT-539313), a selective orexin-1-receptor antagonist, on multiple cytochrome P450probe substrates in vitro and in vivo using a cocktail approach in healthy subjects.

Nivasorexant, a selective orexin-1-receptor antagonist, has recently been assessed in the treatment of humans with binge-eating disorder. Herein, the inhibitory potential of nivasorexant on cytochromes P450 (CYPs) 2C9, 2C19, and 3A4 was evaluated. Human liver microsomes/recombinant CYP enzymes were evaluated in vitro. In vivo, a single-center, open-label, fixed-sequence study was performed in healthy adults to explore the effect of 100 mg nivasorexant administered twice daily (b.i.d.) on the pharmacokinetics (PK) of flurbiprofen (50 mg, CYP2C9), omeprazole (20 mg, CYP2C19), midazolam (2 mg, CYP3A4) making use of a cocktail approach. Plasma PK sampling was performed over 24 h on Day 1 (Cocktail alone), 8 (Cocktail + nivasorexant), and 15 (Cocktail + nivasorexant at steady state). Genotyping of subjects' CYPs was performed while safety and tolerability were also assessed. In vitro, nivasorexant inhibited CYP2C9, 2C19, and 3A4 in competitive inhibition assays with IC50 values of 8.6, 1.6, and 19-44 μM, respectively, while showing a significant time-dependent CYP2C19 inhibition. In 22 subjects, exposure to flurbiprofen, omeprazole, and midazolam was generally higher during concomitant single- (i.e., area under the plasma concentration-time curve [AUC] ratio increased by 1.04-, 2.05-, and 1.56-fold, respectively) and repeated-dose (i.e., AUC ratio increased by 1.47-, 6.84-, and 3.71-fold, respectively) nivasorexant administration compared with the cocktail substrates administered alone. The most frequently reported adverse event was somnolence. According to regulatory guidance, nivasorexant is classified as a moderate CYP2C19 and weak CYP3A4 inhibitor after 1 day and as a weak CYP2C9, strong CYP2C19, and moderate CYP3A4 inhibitor after 8 days of 100 mg b.i.d. administration.

Thyroid dysfunction in children and adolescents affected by undernourished and overnourished eating disorders.

Eating disorders (ED) are one of the most prevalent chronic disorders in adolescents and young adults, with a significantly increasing prevalence in younger children, particularly in girls. Even if obesity in essence is not framed as an eating disorder and has always been considered a separate pathology, ED and obesity could be considered part of a continuum. It has become evident that one condition can lead to another, such as binge eating disorder (BED) and bulimia nervosa, and that they share the same repercussions in terms of psychosocial, metabolic, and nutritional health. This narrative review aims to investigate the hypothalamic-pituitary-thyroid axis in undernourished and overnourished patients with ED, including obesity, in order to highlight the relationship between weight control and thyroid function and its effects and to consider therapeutic and preventive strategies in children and adolescents. Literature data report that thyroid alterations occur in patients with ED, both underweight and overweight, and represent a continuum of changes depending on the severity and time course of the disease involving the endocrine system. Considering the relevant role thyroid hormones (TH) play not only in energy expenditure (EE) but also in metabolic control and cardiovascular risks related to dysmetabolism and mood regulation, continuous monitoring of thyroid homeostasis in patients with ED is mandatory to prevent severe complications and to start early treatment when necessary.

Predictors of neurofeedback treatment outcome in binge-eating disorder: An exploratory study.

Knowledge on predictors for treatment response to psychotherapy in binge-eating disorder (BED) is mixed and not yet available for increasingly popular neurofeedback (NF) treatment targeting self-regulation of aberrant brain activity. This study examined eating disorder- and psychopathology-related predictors for NF treatment success in BED. Patients with BED (N = 78) were randomized to 12 sessions of real-time functional near-infrared spectroscopy (rtfNIRS)-NF, targeting individual prefrontal cortex signal up-regulation, electroencephalography (EEG)-NF, targeting down-regulation of fronto-central beta activity, or waitlist (WL). The few studies assessing predictors for clinical outcomes after NF and evidenced predictors for psychotherapy guided the selection of baseline eating disorder-related predictors, including objective binge-eating (OBE) frequency, eating disorder psychopathology (EDP), food cravings, and body mass index (BMI), and general psychopathology-related predictors, including depressive and anxiety symptoms, impulsivity, emotion dysregulation, and self-efficacy. These questionnaire-based or objectively assessed (BMI) predictors were regressed on outcomes OBE frequency and EDP as key features of BED at post-treatment (t1) and 6-month follow-up (t2) in preregistered generalized mixed models (https://osf.io/4aktp). Higher EDP, food cravings, and BMI predicted worse outcomes across all groups at t1 and t2. General psychopathology-related predictors did not predict outcomes at t1 and t2. Explorative analyses indicated that lower OBE frequency and higher self-efficacy predicted lower OBE frequency, and lower EDP predicted lower EDP after the waiting period in WL. Consistent with findings for psychotherapy, higher eating disorder-related predictors were associated with higher EDP and OBE frequency. The specificity of psychopathological predictors for NF treatment success warrants further examination. This exploratory study firstly assessed eating disorder- and psychopathology-related predictors for neurofeedback treatment outcome in binge-eating disorder and overweight. Findings showed an association between higher eating disorder symptoms and worse neurofeedback outcomes, indicating special needs to be considered in neurofeedback treatment for patients with a higher binge-eating disordersymptom burden. In general, outcomes and assignment to neurofeedback treatment may be improved upon consideration of baseline psychological variables.

Association of participants who screened positive for night eating syndrome with physical health, sleep problems, and weight status in an Australian adult population

BackgroundNight eating syndrome (NES) is a unique eating disorder characterised by evening hyperphagia and nocturnal ingestions which cause significant distress and/or impairment in functioning. Despite the growing literature, NES remains poorly understood and under diagnosed. As such, this study aims to compare the prevalence of physical health conditions in participants with NES when compared to participants without an eating disorder (ED) and participants with other eating disorders (including anorexia nervosa (AN), binge eating disorder (BED) and bulimia nervosa (BN)) in a general population Australian sample of adults.MethodsThe data for this study were obtained from the 2017 Health Omnibus Survey (HOS) a multi-stage, cross-sectional survey, conducted by Harrison Research in South Australia. This current study focused on 2547 participants over 18 years of age and specific questions from this population survey including those related to participant demographics and health.ResultsThis study identified that participants who screened positive for night eating syndrome (spNES) when compared to participants with other eating disorders (ED) or no ED diagnosis, were significantly more likely to have an increased age, be female, have lower levels of education and have lower household income. Additionally, the spNES group was significantly associated with sleep apnoea (p = 0.031), insomnia or other sleep problems (p < 0.0001), increased BMI (p < 0.0001), increased levels of pain/discomfort and lower physical health-related quality of life. Hypertension, hypercholesterolemia, and diabetes were not significantly associated with the spNES group or the “other ED” group which included participants with AN, BED, BN.ConclusionsSeveral physical health problems were found to be significantly associated with the spNES group including sleep problems, increased BMI, increased levels of pain and lower self-reported physical health-related quality of life. Consequently, future research exploring the complex interaction between NES and these medical conditions may provide further insight into the diagnosis, screening tools and management of NES. Additionally, this study highlights the need for future studies which use larger population-based samples.Level of evidenceLevel III.

Reactive hypoglycemia in binge eating disorder, food addiction, and the comorbid phenotype: unravelling the metabolic drive to disordered eating behaviours

BackgroundImpaired metabolic response such as blood glucose fast fluctuations may be hypothesized in binge eating disorder (BED) and food addiction (FA) by virtue of the repetitive consumption of highly processed food. Conversely, rapid changes in plasma glucose (i.e., hypoglycemia) may trigger craving for the same food products. The investigation of early glycemic disturbances in BED and FA could enhance the understanding of the metabolic mechanisms involved in the maintenance of the disorders. Present study investigated hypoglycemia events during a 5-h-long oral glucose tolerance test (OGTT) in people with BED, FA, and the comorbid phenotype. Further, the association between the severity of eating psychopathology and the variability in hypoglycaemia events was explored.MethodsTwo-hundred participants with high weight and no diabetes completed the extended OGTT and were screened for BED, FA, BED-FA, or no-BED/FA. The four groups were compared in hypoglycemia events, OGTT-derived measures, and eating psychopathology. The association between predictors (eating psychopathology), confounders (demographics, metabolic features), and the outcomes (hypoglycemia, early/late hypoglycemia, severe hypoglycemia, reactive hypoglycemia) was examined through logistic regression.ResultsHypoglycemia in general, and reactive hypoglycemia were highly frequent (79% and 28% of the sample, respectively). Hypoglycemia events (< 70 mg/dL) were equally experienced among groups, whilst severe hypoglycemia (< 54 mg/dL) was more frequent in BED at the late stage of OGTT (5 h; χ2 = 1.120, p = .011). The FA and BED groups exhibited significantly higher number of reactive hypoglycemia (χ2 = 13.898, p = .003), in different times by diagnosis (FA: 210′–240′; BED: at the 270′). FA severity was the only predictor of early and reactive hypoglycemia.ConclusionsPeople with BED or FA are prone to experiencing reactive hypoglycemia; FA severity may predict early and symptomatic hypoglycemia events. This can further reinforce disordered eating behaviours by promoting addictive responses, both biologically and behaviourally. These results inform professionals dealing with eating disorders about the need to refer patients for metabolic evaluation. On the other hand, clinicians dealing with obesity should screen for and address BED and FA in patients seeking care for weight loss.

The Sick, Control, One Stone, Fat, Food (SCOFF) is a Valid Eating Disorder Questionnaire to Use With Transgender Youth.

Transgender youth experience elevated rates of eating disorders, yet few screening measures have been validated with transgender patients. The purpose of this study was to provide initial evidence for the internal consistency and convergent validity of the Sick, Control, One Stone, Fat, Food (SCOFF) in a sample of transgender youth. Two hundred eight participants completed the SCOFF as part of a routine screening protocol. Exploratory factor analysis and confirmatory factor analysis were used to establish the factor structure of the SCOFF in this sample. Relationships between the SCOFF, Adolescent Binge Eating Disorder (ADO-BED), Nine-Item Avoidant/Restrictive Intake Disorder (NIAS), Patient Health Questionnaire 9 (PHQ-9), Generalized Anxiety Disorder 7 (GAD-7), and demographic characteristics were explored. The SCOFF was significantly related to all convergent validity variables, with moderate correlations with other eating disorder scales (ADO-BED and NIAS). The SCOFF is a valid measure to screen for eating disorders among transgender youth and young adults.

The relationship of food addiction with binge eating disorder and obesity: A network analysis study

Food addiction (FA) has been associated with binge eating disorder (BED) and obesity at varying levels of severity and treatment outcomes. Despite much debate and scientific interest in FA, the mechanisms that underlie its co-occurrence with both conditions are not yet well understood. In order to understand this relationship, this study explores FA in a clinical sample of individuals with BED and obesity using network analysis (NA). A total of 303 patients (151 with BED and 152 with obesity) completed a battery of tests that investigated eating psychopathology, eating behaviours, emotional dysregulation, depression and FA. Two different NAs were conducted to investigate the interaction between these variables and FA. The BED and obesity groups were comparable in age (38 ± 14 vs. 42 ± 13 years), body mass index (38.8 ± 8.5 vs 42.4 ± 7.8), sex and demographics. According to the expected influence values, binge eating severity and depression were identified as the central nodes in both networks. In the BED group, binge eating severity was the central node and showed strong connections to both FA and grazing. In contrast, in the obesity group, depression was the central node, but its connections were weak, with only marginal associations to FA. These results suggest that FA represents an important and distinct construct of the two populations. In patients with BED, FA is intimately connected to other loss-of-control-related eating behaviours, such as binge eating and grazing. Conversely, in those with obesity, depression explains the relationship of FA with pathological eating behaviours. The presence of FA seems to be a distinguishing characteristic in the psychopathology of patients suffering from obesity with and without BED, and this could have implications for the prevention, treatment and management of these disorders.

A feminist approach to eating disorders in China: a qualitative study

BackgroundAs women continue to be more at risk from eating disorders, gender has often been a focus of concern in transcultural research. Yet feminist, qualitative studies which prioritize the voices of women/girls remain rare within transcultural work suggesting the need for greater interaction between these fields. This article seeks to contribute to the exploration of the applicability of feminist paradigmslargely developed in the West—to experiences of EDs in non-western contexts.MethodsThis article draws on semi-structured interviews with 12 women from urban China with self-reported experience of Bulimia Nervosa (BN) and binge eating disorder (BED) in order to explore the complex ways in which gender may be implicated within eating/body distress from a transcultural point of view. The data is analysed through Reflexive Thematic Analysis.ResultsThe data analysis suggested two broad themes: (1) Chinese versus Western codes for judging female appearance: from surveillance to liberation (2) Discipline, appetite and control: the gendered/cultural meanings of binging and purging. In terms of the first theme, many participants had spent time in the West which was understood as a less regulated context in terms of gendered body surveillance and eating. Complicating existing assumptions about the ‘Westernisation’ thesis, different communication codes and peer interactions across Chinese and Western contexts played a central role in how participants experienced their bodies. In the second theme, binging and purging emerged as a way to manage a number of contradictions surrounding Chinese femininity, including respecting familial food cultures, contradictory discourses on female ‘appetite’, and the need to display a female body which signified cultural imperatives of self-restraint and discipline.ConclusionsThe data emphasises the importance of examining the culturally specific meanings of eating problems and their gendered contexts, whilst there is clearly much that echoes Western feminist work on Western samples. Although limited, the study crucially points to the importance of examining how ED subcategories other than AN can be explored from a transcultural and feminist point of view.

Eating disorders occur at high rates in adolescents with epilepsy and are associated with psychiatric comorbidities and suicidality.

To assess the occurrence rate, characteristics, and impact of eating disorders (EDs) in adolescents with epilepsy. In this observational study, adolescents with epilepsy seen in a single center between 2013 and 2022 who had comorbid EDs were compared to two control groups of adolescents with only epilepsy and only EDs. Patients with intellectual disability or autism spectrum disorder were excluded. Data retrieved included demographic and anthropometric details and clinical variables relating to seizure types, EDs, and psychiatric disorders and behaviors. A total of 376 subjects were included in the study: 84 adolescents with both epilepsy and eating disorders, 135 with only epilepsy, and 157 with only EDs. The rate of EDs in adolescents with epilepsy was 7.0% (95% confidence interval [CI] 5.6%-8.5%) overall, 11.3% (95% CI 8.8%-14.3%) in females, and 3.1% (95% CI 1.9%-4.8%) in males. The median (interquartile range [IQR]) time difference between the onset of epilepsy to an ED was 1.6 (.5-3.6) years. Among adolescents with epilepsy, those with an ED were more likely to be female (p = .001) and have a lower body mass index z-score (zBMI) percentile (p < .001). Epilepsy type, seizure frequency, or seizure duration were not specific for having or not having EDs. Among adolescents with EDs, those with epilepsy had a younger onset of their EDs (p < .001), included relatively more males (p = .007), and consisted of more cases of anorexia-nervosa-restrictive type (p < .001), and fewer cases of bulimia nervosa (p = .04) and binge eating disorder (p = .003). Adolescents with epilepsy and a comorbid ED were more likely to have psychiatric comorbidities such as depression, anxiety, and suicidality than adolescents with only epilepsy or EDs. EDs should be suspected and screened for in intellectually intact female and male adolescents with epilepsy, irrespective of their epilepsy type. If disturbed eating behaviors or EDs are identified, further evaluation should be directed at detecting other psychopathologies, including suicidality.

Functional Connectivity Mechanisms Underlying Symptom Reduction Following Lisdexamfetamine Treatment in Binge-Eating Disorder: A Clinical Trial

BackgroundSpeculation exists as to whether lisdexamfetamine dimesylate (LDX) acts on the functional connectivity (FC) of brain networks that modulate appetite, reward, or inhibitory control in binge-eating disorder (BED). Better insights into its action may help guide the development of more targeted therapeutics and identify who will benefit most from this medication. Here, we use a comprehensive data-driven approach to investigate the brain FC changes that underlie the therapeutic action of LDX in patients with BED. MethodsForty-six participants with moderate to severe BED received LDX titrated to 50 or 70 mg for an 8-week period. Twenty age-matched healthy control participants were also recruited. Resting-state functional magnetic resonance imaging was used to probe changes in brain FC pre- and post treatment and correlated with change in clinical measures. ResultsNinety-seven percent of trial completers (n = 31) experienced remission or a reduction to mild BED during the 8-week LDX trial. Widespread neural FC changes occurred, with changes in default mode to limbic, executive control to subcortical, and default mode to executive control networks associated with improvements in clinical outcomes. These connections were not distinct from control participants at pretreatment but were different from control participants following LDX treatment. Pretreatment connectivity did not predict treatment response. ConclusionsFC between networks associated with self-referential processing, executive function, and reward seem to underlie the therapeutic effect of LDX in BED. This suggests that LDX activates change via multiple systems, with most changes in compensatory networks rather than in those characterizing the BED diagnosis.

Accumbens connectivity during deep-brain stimulation differentiates loss of control from physiologic behavioral states

BackgroundLoss of control (LOC) eating, the subjective sense that one cannot control what or how much one eats, characterizes binge-eating behaviors pervasive in obesity and related eating disorders. Closed-loop deep-brain stimulation (DBS) for binge eating should predict LOC and trigger an appropriately timed intervention. Objective/hypothesisThis study aimed to identify a sensitive and specific biomarker to detect LOC onset for DBS. We hypothesized that changes in phase-locking value (PLV) predict the onset of LOC-associated cravings and distinguish them from potential confounding states. MethodsUsing DBS data recorded from the nucleus accumbens (NAc) of two patients with binge eating disorder (BED) and severe obesity, we compared PLV between inter- and intra-hemispheric NAc subregions for three behavioral conditions: craving (associated with LOC eating), hunger (not associated with LOC), and sleep. ResultsIn both patients, PLV in the high gamma frequency band was significantly higher for craving compared to sleep and significantly higher for hunger compared to craving. Maximum likelihood classifiers achieved accuracies above 88% when differentiating between the three conditions. ConclusionsHigh-frequency inter- and intra-hemispheric PLV in the NAc is a promising biomarker for closed-loop DBS that differentiates LOC-associated cravings from physiologic states such as hunger and sleep. Future trials should assess PLV as a LOC biomarker across a larger cohort and a wider patient population transdiagnostically.

Homoeopathic Treatment for Eating Disorders: A Comprehensive Overview and Promising Therapeutic Approach

There is a widespread belief that eating disorders stem from lifestyle choices. However, it is essential to recognize that eating disorders are severe and potentially fatal illnesses, characterized by obsessions with food, body weight, and shape. Various eating disorders include anorexia nervosa, bulimia nervosa, night-eating syndrome, eating disorders not otherwise specified, and binge-eating disorders. These disorders can affect individuals regardless of age, gender, socioeconomic status, or cultural background, and they have been responsible for approximately 7000 deaths per year as of 2010. Timely detection plays a crucial role in enhancing the chances of recovery from eating disorders. Therefore, being aware of warning signs is of utmost importance. This review delves into the different types of eating disorders and explores their treatment through Homeopathy. Keywords: Eating disorders, anorexia nervosa, bulimia nervosa, binge eating disorder, pathophysiology, Homoeopathy.

Reducing binge eating through behavioral-focused versus emotion-focused implementation intentions in patients with binge eating disorder or bulimia nervosa: An experimental approach

Binge eating disorder (BED) and bulimia nervosa (BN) are characterized by recurrent binge eating, episodes of consuming large amounts of food in a discrete period of time associated with a loss of control. Implementation intentions are explicit if-then plans that engender goal-directed action, and rely less on cognitive control than standard treatment options. In a sample with BED and BN, we compared two implementation intention conditions to a control condition. In the behavior-focused condition, implementation intentions targeted binge eating behaviors. In the emotion-focused condition, implementation intentions targeted negative affect preceding binge eating. In the control condition, only goal intentions were set. Each condition comprised three sessions. Participants kept food diaries for four weeks. Compared to the control condition both implementation intention conditions showed significant and large reductions of binge eating that persisted for six months. Effects did not differ between the behavior-focused and emotion-focused implementation intention conditions. These results demonstrate that three sessions on implementation intention formation can lead to long-term reductions in binge eating in patients with BED or BN. Learning how to form implementation intentions seems a recommendable addition to the current standard treatment. Future research could investigate the added value of fully personalized implementation intentions. Clinical trial registration numberNL52600.068.15.

Responses to bright light exposure in individuals with binge-spectrum eating disorders characterized by high dietary restraint and negative affect.

Circadian rhythm disruptions are associated with binge eating, can be causal of negative mood, and may be corrected with bright light exposure. A subtype of individuals with binge-spectrum eating disorders are characterized by combined high dietary restraint and negative affect. These individuals have higher eating disorder psychopathology and poorer treatment response. We aimed to test the targeted effects of morning bright light exposure on individuals with binge-spectrum eating disorders, hypothesizing significant reductions in binge eating for those characterized by high dietary restraint and negative affect. Participants (N = 34 females with binge-eating disorder and bulimia nervosa) used a morning bright light and normal light for 10 consecutive days each, in randomized order. They completed the Change in Eating Disorder Symptoms (CHEDS) scaleat baseline, day 12 (when they switched lamps), and day 22. We conducted moderation analyses, clustering data by person, controlling for order, and examining the effect of light condition on binge eating according to baseline restraint and negative affect. At high levels of combined dietary restraint and negative affect, participants experienced a reduction in binge eating and food preoccupation following exposure to morning bright light. There were no changes in restrictive eating, body preoccupation, body dissatisfaction, or body checking following exposure to morning bright light for these individuals. These findings suggest that morning bright light may be a useful adjunct to empirically supported eating disorder treatments that target binge eating, especially for individuals characterized by the difficult to treat restraint/negative affect subtype. At high levels of combined dietary restraint and negative affect, participants with binge-spectrum eating disorders experienced a reduction in binge eating and food preoccupation following exposure to morning bright light. These findings suggest that morning bright light may be a useful adjunct to empirically supported eating disorder treatments that target binge eating, especially for individuals characterized by the difficult-to-treat restraint/negative affect subtype.

Adding executive function training to cognitive behavioral therapy for binge eating disorder: A pilot randomized controlled trial

Evidence-based treatments for binge eating disorder (BED), such as cognitive behavioral therapy (CBT) lead to successful outcomes only about half the time. Individuals with BED often have measurable deficits in executive function (EF) that may challenge adherence to or impact of cognitive behavioral intervention components. The aim of this study was to evaluate the impact of adding EF training to CBT by combining CBT with a compensatory cognitive training approach (EF-CBT). Participants were 32 adults with BED, overweight/obesity, and comorbid anxiety or depression who were randomly assigned to four months of group treatment in either standard CBT or EF-CBT. Outcomes were assessed at baseline, post-treatment, and at 2-month follow-up. Results showed that EF-CBT was feasible and acceptable, comparable to CBT. Both groups significantly decreased loss of control (LOC) days, clinical impairment, and depression at post-treatment and 2-month follow-up; though there were no differences between groups. Neither group significantly reduced anxiety or weight. Exploratory analyses found that participants with lower EF treated with EF-CBT were less likely to have LOC at post-treatment than those with lower EF treated with CBT. Higher self-monitoring rates during treatment were associated with lower LOC at post-treatment and participants with lower EF were more likely to self-monitor in the EF-CBT arm relative to the CBT arm. These findings suggest that EF-CBT is feasible, acceptable and efficacious, although larger scale research is needed. EF-CBT may be particularly suited for individuals with BED who have lower EF.

Factors Associated With Binge Eating Among Chinese University Students in Hong Kong.

Binge eating (BE), defined as uncontrolled overconsumption of food, is associated with poorer health status. We aimed to characterize the factors associated with BE among Chinese college students. University students from two universities in Hong Kong (n = 267) completed an anonymous online questionnaire that contained background questions, the Binge Eating Disorder Screener-7, Depression, Anxiety, and Stress Scales-21 (DASS-21), and Adolescent Lifestyle Questionnaire (ALQ) between June and August 2022. Multiple logistic regression and two-sample independent t-test were conducted to test the association of study variables with BE. In this university sample, 36.8% of males and 21.4% of females were classified as engaging in BE in the last three months. BE was statistically significantly associated with higher body mass index (BMI), more depressive symptoms, and lower ALQ nutrition scores among males and lower BMI, more depressive, anxiety, and stress symptoms among females. BE was significantly associated with various factors in both male and female university students in Hong Kong; thereby, university health promotion programs should include the management of BE. BE should be a prominent focus of health promotion interventions in conjunction with mental health promotion in the region.

Binge eating disorder and food addiction occurrences among adult Jordanian women with obesity

Introduction: The aim of the study was to estimate the occurrences of binge eating disorder (BED) and food addiction (FA) in Jordanian women with obesity and to explore their relationships with selected potential risk factors for obesity. Methods: A descriptive case series design that involved a total of 842 women with obesity was conducted. The occurrences of BED and FA were evaluated using the Questionnaire on Eating and Weight Patterns-5 (QEWP-5) and Yale Food Addiction Scale 2.0 (YFAS 2.0). Results: The overlapping of BED and FA (BED+FA) was the most frequent category constituting 53.7%. The second highest category was BED comprising 25.0%, followed by FA comprising 9.0%. Body mass index (BMI) and waist circumference (WC) were significantly higher in the BED+FA group as compared to all other groups. The FA group (41.3%) had significantly the lowest level of sleeping hours. BED (58.0%) and BED+FA (66.1%) groups were significantly higher in consuming more than three snacks per day. BED and/or FA-free group had significantly higher level of water intake of &gt;5 cups/day. Conclusions: The frequencies of BED and FA were relatively high among obese Jordanian women. The study demonstrated an overlap between BED and FA, highlighting its associations with increased BMI and WC in a selected sample of obese women. The study suggested that BED, FA, and the overlapping of both conditions were associated with greater tendencies towards an unhealthy pattern of eating practices, fluid intake, and sleeping habits.
