However, inconsistent replication of the subscale structure raises concern about validity. To provide a rigorous test of the EDE-Q's dimensionality and item-quality, we applied modern and classical test theory approaches to data obtained from a large, transdiagnostic sample of people with clinical eating disorders.Method: We analyzed data from 1197 individuals (Mage = 27.9 years, SD = 10.08, 95% female) with various eating disorders, who had been assessed for treatment at a specialized program. Exploratory analyses (including Parallel Analyses), Confirmatory Factor Analyses (CFA) and graded-response Item Response Theory (IRT) analyses, were conducted with Mplus.Results: Factor analyses showed inappropriate fit to the original EDE-Q subscales, as well as for alternative 1,2,3, and 4-factor solutions. Parallel analyses suggested a one-dimensional structure as best fit. IRT analyses showed substantial variability in EDE-Q-item quality and indicated that five items (fear of weight gain, feeling fat, desire to lose weight, importance of weight, importance of shape) were most pertinent to determining severity. The construct validity of the five EDE-Q items was confirmed by a CFA, showing excellent fit.Discussion: Our results suggest that EDE-Q scores are best interpreted as spanning a one-factor continuum. IRT results suggest that some items are more pertinent than others for determining eating-disorder severity. Results could be useful for establishing short EDE-Q versions, such as a five-item version, which, in turn, would be helpful for measurement-based clinical practice and for data-collection in epidemiological and experimental studies.","PeriodicalId":51067,"journal":{"name":"International Journal of Eating Disorders","volume":" ","pages":""},"PeriodicalIF":4.7,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142645036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the directionality of relations between these variables remains under-characterized, particularly within treatment settings.Method: We used bivariate latent change score models to explore longitudinal associations between anxiety and ED symptoms in a sample of ED patients (N = 548, 93.2% female, Mage = 21.16, 78.8% White, 79.6% Non-Hispanic/Latinx) throughout intensive treatment and at 6- and 12-month follow-up.Results: Best-fitting models exploring change in each variable independently (i.e., univariate models) suggested that changes in ED and anxiety symptoms decreased over time, but that change was influenced by an individual's symptom severity at the previous timepoint. Models exploring associations between changes in both variables over time (i.e., bivariate latent change score models) suggested the best fit for a model where both anxiety and ED symptoms at one timepoint were associated with later change in the other. Specifically, parameters within these models suggested that higher levels of anxiety were associated with increased subsequent reductions in ED symptoms, whereas elevations in ED symptoms were associated with decreased later reductions in anxiety.Conclusions: Our findings suggest that anxiety and ED symptoms are intricately related both within and outside of intensive treatment. Future multi-modal research exploring real-time links between anxiety and ED symptoms throughout treatment is critical to extend this work and inform improvements in targeted, mechanistic interventions for this population.","PeriodicalId":51067,"journal":{"name":"International Journal of Eating Disorders","volume":" ","pages":""},"PeriodicalIF":4.7,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142645039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are two case reports totaling six adult females who experienced complete remission of AN following a treatment comprised of ketogenic diet (targeting metabolism) with ketamine infusions (targeting psychiatric origins), but no study has determined the efficacy of ketogenic diet, alone. We addressed this gap in knowledge, with exploration of potential molecular mechanisms, using an animal model.Method: Adult C57BL6 female mice underwent 2 or 3 cycles of activity-based anorexia (ABA1, ABA2, ABA3), an animal model of AN relapse, in which AN-like maladaptive behaviors of hyperactivity and voluntary food restriction are elicited when wheel access is combined with food restriction. ABA was categorized as severe, based on weight loss ≥ 20%, food restriction-evoked increase in wheel counts > 10,000/6 h, and crouching/grimace, and compared across two groups: (1) KG, fed ketogenic food continuously (N = 25); and (2) CON, fed standard diet (N = 28).Results: 86% of CON versus none of the KG were crouching with grimace during ABA1. 93% of CON versus 11% of KG lost weight severely during ABA2 (p < 0.001, 8% difference of group mean weights). Severe hyperactivity was prevalent among CON (86%) and rare for KG (4%) during ABA2 (p < 0.001 on all food-restricted days). ABA up-regulated BDNF (brain-derived neurotrophic factor) in the hippocampus of both groups but ketone body, β-hydroxybutyrate, in urine was increased only among KG.Discussion: Ketogenic diet may reduce severity of AN relapse through reduction of compulsive exercise, via mechanisms that are in addition to BDNF up-regulation and involve β-hydroxybutyrate.","PeriodicalId":51067,"journal":{"name":"International Journal of Eating Disorders","volume":" ","pages":""},"PeriodicalIF":4.7,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142645042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research has begun to explore ED treatment outcomes and experiences in this population, however current understandings are poorly integrated. The current review therefore sought to explore the impact of ED treatment on Autistic people and those with higher Autistic traits.Method: A convergent, segregated approach was used, independently evaluating quantitative then qualitative studies before integrating findings into a coherent narrative synthesis.Results: Autistic people and people with higher Autistic traits report poorer experiences of treatment and may be at increased risk of inpatient admission and prolonged inpatient treatment, possibly explained by difficulties with treatment timeframes and a lack of autism-informed support. Both groups reported similar improvements in ED symptoms and BMI. Higher rates of psychosocial difficulties pre-and post-treatment were reported in those with higher Autistic traits, and emotion-focused interventions were felt to be particularly relevant to Autistic presentations of EDs. Concerns were reported as to how well aligned group-based programs and cognitive-based interventions are for Autistic individuals and those reporting higher Autistic traits.Discussion: Future research in diagnosed autism samples is urgently needed to develop a more robust understanding of Autistic outcomes and experiences. Review findings demonstrate the need for increased understanding of ED presentations and the possible need for treatment adaptations, for Autistic people or those with higher Autistic traits.","PeriodicalId":51067,"journal":{"name":"International Journal of Eating Disorders","volume":" ","pages":""},"PeriodicalIF":4.7,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142632102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cost of illness (COI) studies, burden of disease, and other cost studies that reported costs in monetary values were included, and cost-effectiveness analysis studies were excluded. The quality of COI studies was assessed using Schnitzler's checklist. All cost estimates were converted into 2024 USD purchasing power parity (PPP). The PROSPERO registration number is CRD42022358136.Findings: Twenty-six studies were identified for inclusion in this review, with 11 COI studies. The nationwide annual financial cost of EDs is estimated at PPP-USD 70.5 billion. Indirect costs contributed 70%-93% of total financial costs in the reviewed studies. Intangible costs (burden of disease) were estimated to be PPP-USD 355.6 billion. About half of the COI studies met 60% of the elements of Schnitzler's checklist, either completely or partly.Discussion: The number of COI studies has more than doubled in the last 10 years. Findings can inform healthcare administrators/policymakers to understand the magnitude of this burden when setting healthcare priorities and allocating resources to maximize social welfare. However, there are variations in the methods (thus quality) and perspectives used to assess this economic burden.

Largely owing to the phenotypic heterogeneity, the underlying pathophysiological mechanisms are relatively unknown. Recently, the communication between microorganisms within the gastrointestinal tract and the brain-the so-called microbiota-gut-brain axis-has been implicated in the pathophysiology of eating disorders. This Spotlight review sought to investigate and conceptualize the possible ways that the microbiota-gut-brain axis is involved in ARFID to drive future research in this area.Method: By relating core symptoms of ARFID to gut microbiota and its signaling pathways to the brain, we evaluated how the gut microbiota is potentially involved in the pathophysiology of ARFID.Results: We hypothesized that the restricted type and amount of food intake characteristic of ARFID diminishes gut microbial diversity, including beneficial bacteria and their metabolites capable of signaling to the brain, to modulate biopsychological pathways relevant to ARFID: homeostatic signaling, food reward, interoception, sensory sensitivity, disgust, perseveration, fear-based learning, and mood. Candidate signaling mechanisms include microbial-induced effects on inflammation, cortisol, and neurotransmitters such as dopamine and serotonin.Discussion: Through reviewing the extant evidence, we conceptualized a new theoretical framework of ARFID with an emphasis on microbiota-gut-brain axis signaling to inform future research. Although more research is necessary to evaluate this theoretical model, the tentative evidence suggests that therapeutics specifically targeting the gut microbiota for the treatment of ARFID symptomatology warrants more investigation.","PeriodicalId":51067,"journal":{"name":"International Journal of Eating Disorders","volume":" ","pages":""},"PeriodicalIF":4.7,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142632105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
