A dearth of information exists on differences in quality of life across eating disorder diagnoses. The purpose of the current study was to examine quality of life among a large sample of adults with one of six eating disorder diagnoses: anorexia nervosarestricting subtype (AN-R), AN binge/purge subtype (AN-BP), bulimia nervosa (BN), binge eating disorder (BED), avoidant/restrictive food intake disorder (ARFID), and otherwise specified feeding or eating disorder (OSFED). Participants were 1268 adults receiving treatment for an eating disorder across multiple levels of care who completed a measure of quality of life, the WHOQOL-BREF, at admission. Adjusted pairwise comparisons with multiple comparison correction found significant differences among eating disorder groups, even after controlling for age, sex, level of care, body mass index (BMI), and the interaction between BMI and eating disorder diagnosis. Among the five significant findings, four of them involved differences in those with ARFID in comparison to the other eating disorder diagnoses. On the physical health subscale, individuals with BN scored significantly better than did individuals with ARFID. On the psychological subscale, patients with ARFID had significantly better quality of life than those with BN, BED and OSFED. On the social relationships subscale, the BED group scored significantly worse than those with AN-BP. This large study of adults with eating disorders suggests that there are meaningful differences among eating disorder diagnostic groups in quality of life. Full article

Objectives: To assess associations between body weight metrics and eating disorder (ED)-psychopathology in adolescents with anorexia nervosa (AN) at baseline and four weeks post-discharge (4-week follow-up) from inpatient psychiatric multimodal treatment (IMT), calculating full and partial body mass index (BMI) percentile/ED-psychopathology remission rates. Methods: Secondary analysis of a prospective observational cohort study in adolescents (12–18 years) with AN-restricting (AN-R)/-binge–purge (AN-BP), and atypical AN (AAN). Body weight metrics and ED-psychopathology (Eating Disorder Examination Questionnaire, EDE-Q) were assessed at baseline and 4-week follow-up. Remission at 4-week follow-up was calculated by applying German-AN-S3-guidelines-based vs. DSM-5 criteria. Results: In 40 adolescents (mean age = 15.6 ± 1.5 years; females = 90%; BMI z-score = −2.59 ± 1.07) receiving IMT (median duration = 118 (IQR = 90–150) days), BMI z-score increased (−2.61 to −1.04, p < 0.001) and EDE-Q global score decreased (3.26 to 1.81, p < 0.001) from baseline to 4-week follow-up. Greater weight gain/week during IMT had a positive impact on ED-psychopathology at 4-week follow-up. In multivariable analyses, greater BMI z-score improvement was independently predicted by lower baseline BMI z-score (p < 0.001) and fewer baseline comorbid psychiatric diagnoses (p = 0.034) (R²_Adjusted = 0.545). Greater EDE-Q global score improvement was independently predicted by typical vs. atypical AN (p = 0.005), higher baseline BMI z-score (p = 0.012), and higher baseline EDE-Q restraint (p = 0.048) (R²_Adjusted = 0.376). By applying stricter S3-guideline-based vs. DSM-5 BMI percentile criteria, full BMI percentile/ED-psychopathology remission was lower (12.5% vs. 50.0%, p = 0.001), while non-remission was higher (25.0% vs. 5.0%, p = 0.001). Conclusions: The complex relationships between body weight metrics, ED-psychopathology, and treatment outcome trajectories in AN, including treatment response and remission criteria, require further investigation.

Background/Objective: Our current knowledge regarding ethnic/racial differences in the incidence of and risk factors for eating disorder onset is relatively limited. We examined whether the baseline prevalence and incidence of onset of any eating disorder over follow-up and the risk factors that predict future onset of any eating disorder differ for various ethnic/racial groups. Methods: Data were collected from females across a wide age range (N = 1952; White = 61%, Hispanic = 17%, Asian = 14%, Black = 5%, and Native American = 3%; M baseline age = 19.7, SD = 5.7; baseline age range: 13–64) who completed self-report questionnaires and a diagnostic interview at baseline and then annually over 3 years. We ran two chi-square tests that examined how ethnicity/race were related to eating disorders at baseline and future onset as well as a series of logistic regression models that tested whether baseline risk factors and prodromal symptoms were differentially related to future eating disorder onset across ethnic/racial groups. Results: The diagnostic prevalences as well as the predictive relationship of a risk factor and a prodromal symptom with eating disorder onset were very similar across ethnic/racial groups, with only one instance where the magnitude of the predictive effects differed across two ethnic/racial groups; lower zBMI was predictive among White women, whereas higher zBMI was predictive among Black women. Conclusions: Overall, risk factors and prodromal symptoms are similar across the examined ethnic/racial groups, suggesting that we can implement the same prevention programs for women with the same risk factors, regardless of their ethnic/racial identities.

Emotion dysregulation and altered interoceptive processing are increasingly recognized as core processes in eating disorder (ED) psychopathology. Difficulties in identifying, tolerating, and regulating negative emotional states may interact with reduced trust in bodily signals and distorted interpretation of hunger and satiety cues, contributing to maladaptive eating behaviors. The aim of this PRISMA-guided qualitative systematic review was to synthesize original empirical evidence on the interaction between emotion dysregulation and interoceptive processing in EDs, with particular attention to how emotional distress may be misinterpreted as physical hunger or food-related urges. A systematic search of PubMed and Scopus identified 78 records; after removal of duplicates and screening procedures, 24 original empirical studies were included in the qualitative synthesis. Across ED presentations, emotion dysregulation consistently emerged as a central transdiagnostic process associated with symptom severity, impulsivity, maladaptive eating behaviors, and related risk outcomes. Interoceptive alterations were widely reported, particularly involving reduced body trust and distorted interpretation of internal sensations rather than a uniform deficit in interoceptive sensitivity. The reviewed studies also showed that emotional states and cognitive expectations may shape the appraisal of hunger and satiety cues, contributing to the misinterpretation of emotional distress as physiological need across restrictive, binge-purge, and binge-eating presentations. The findings support a close interplay between emotion dysregulation and altered interoceptive processing in EDs and highlight the clinical relevance of interventions that integrate emotion regulation and interoceptive awareness to promote more adaptive eating behaviors.

This study aimed to examine the differences in self-compassion (SC) subcomponents between anorexia nervosa (AN) subtypes, the restricting type (ANR) and binge-eating/purging type (ANBP), with a focus on perceived isolation and self-judgment. This retrospective exploratory study included 40 patients with AN at a Japanese tertiary hospital. The participants completed the Self-Compassion Scale, Patient Health Questionnaire-9, and Eating Disorder Examination Questionnaire. Between-group comparisons were conducted using t-tests, and logistic regression was used to examine associations with the AN subtype. Compared with the ANR group, the ANBP group was older at the time of assessment, had a longer illness duration, and showed significantly more depressive symptoms, more severe eating pathologies, and lower SC scores. Specifically, patients with ANBP had significantly higher scores on the negative SCS subscales of self-judgment and isolation, indicating greater self-criticism and perceived isolation. In logistic regression analyses adjusting for the EDE-Q mean score, higher isolation scores were significantly associated with the ANBP subtype (odds ratio = 3.28, 95% confidence interval: 1.37–9.63, p = 0.01). In this exploratory sample, perceived isolation was more prominent in ANBP and may reflect affective and interpersonal difficulties related to this subtype. These findings should be interpreted as hypothesis-generating and warrant replication in larger (ideally multi-site and longitudinal) samples. If replicated, targeting these self-compassion dimensions may inform the development of subtype-sensitive interventions. Full article

Aims. In the present study, we investigated the associations between the three identity dimensions of Kaufman (Consolidated Identity, Disturbed Identity, Lack of Identity) and symptoms of personality disorders (PDs) in 176 female inpatients with an eating disorder (ED). We examined five aspects: the prevalence of categorical PD diagnoses in patients with EDs; the relationship between dimensional PD scores and identity dimensions as well as their relationships with age and ED subtype; and the unique variance in dimensional PD scores explained by identity dimensions, while controlling for age and ED subtype. Methods. To assess identity functioning, we made use of the Self-Concept and Identity Measure, and to assess PDs, we used the categorical and dimensional scores of the Assessment of DSM-IV Personality Disorders. Results. The findings showed that the avoidant, obsessive–compulsive, and borderline categorical PDs were the most frequently reported PDs. Age was negatively related to all Cluster B PDs and Disturbed Identity, and binge-eating/purging ED patients reported significantly more Cluster B PD features compared to restrictive ED patients. ED subtype and identity dimensions were unrelated. Correlational analysis showed that all dimensional PD scores were positively related to Disturbed Identity and Lack of Identity and negatively related to Consolidated Identity. The results of the hierarchical regression analyses showed that Cluster A PDs were significantly predicted by Lack of Identity, controlled for age and ED subtype. Additionally, Cluster B PDs were significantly predicted by Disturbed Identity. Finally, two of the three cluster C PDs were predicted by Lack of Identity (avoidant and obsessive–compulsive PD), whereas the dependent PD was explained by Disturbed Identity. Conclusions. The co-occurrence of identity issues in both PDs and EDs underscores the role of identity as a transdiagnostic feature. Accordingly, using identity-based interventions in treatment may have broad therapeutic benefits across these disorders. Full article

Emerging evidence highlights the critical role of the gut microbiota in the development and progression of eating disorders (EDs), particularly in women, who are more frequently affected by these conditions. Women with anorexia nervosa, bulimia nervosa, and binge eating disorder exhibit distinct alterations in gut microbiota composition compared to healthy controls. These alterations, collectively termed dysbiosis, involve reduced microbial diversity and shifts in key bacterial populations responsible for regulating metabolism, inflammation, and gut–brain signaling. The gut microbiota is known to influence appetite regulation, mood, and stress responses—factors closely implicated in the pathogenesis of EDs. In women, hormonal fluctuations related to menstruation, pregnancy, and menopause may further modulate gut microbial profiles, potentially compounding vulnerabilities to disordered eating. Moreover, the restrictive eating patterns, purging behaviors, and altered dietary intake often observed in women with EDs exacerbate microbial imbalances, contributing to intestinal permeability, low-grade inflammation, and disturbances in neurotransmitter production. This evolving understanding suggests that microbiota-targeted therapies, such as probiotics, prebiotics, dietary modulation, and fecal microbiota transplantation (FMT), could complement conventional psychological and pharmacological treatments in women with EDs. Furthermore, precision nutrition and personalized microbiome-based interventions tailored to an individual’s microbial and metabolic profile offer promising avenues for improving treatment efficacy, even though these approaches remain exploratory and their clinical applicability has yet to be fully validated. Future research should focus on sex-specific microbial signatures, causal mechanisms, and microbiota-based interventions to enhance personalized treatment for women struggling with eating disorders.

Background/Objectives: To inform person-centred clinical practice, it is important to know what features may predict or moderate treatment outcomes. Thus, we investigated pre-treatment clinical features and mid-therapy reduction in loss of control over eating (MTLOCE), including impacts on treatment outcomes of a new manualised psychotherapy, a healthy approach to weight management and food in eating disorders (HAPIFED). HAPIFED was developed as an integrated psychological and behavioural treatment for individuals with bulimia nervosa or binge eating disorder, which are co-morbid with a high body mass index (BMI). Methods: In total, 50 participants were randomised to HAPIFED and 48 were randomised to the control cognitive behaviour therapy-enhanced group. Assessments included mental health-related quality of life (MHRQoL), eating disorder symptom severity, binge-eating frequency, BMI, and loss of control over eating (LOCE) at baseline, mid-treatment, end-treatment, and 6 and 12 months end of follow-up (EndFU). These were measured with the SF-12, the EDE-Q, and the LOCES, respectively. Linear and negative binomial mixed models were used. Missing data were imputed multiple times, assuming intention of treatment for the analysis. Results: Pre-treatment eating disorder symptom severity, MHRQoL, and BMI positively predicted eating disorder symptom severity, MHRQoL, and BMI up to 6 and 12 months end of follow-up. Mid-treatment LOCE MTLOCE predicted improved MHRQoL (coefficient = 0.387, 95% CI 0.0824–0.6921, p = 0.004), reduced binge-eating frequency (IRR = 0.5637, 95% CI 0.3539–0.8977, p = 0.0191), and eating disorder symptom severity (coefficient= −0.65, 95% CI −1.0792–−0.2217, p = 0.0139). Neither purging nor illness duration were a significant predictor of any of the outcomes. The effect of HAPIFED was not moderated by baseline weight/BMI but was moderated negatively by MTLOCE for binge-eating frequency (coefficient = −0.636, SE = 0.28, p < 0.05, IRR = 0.529) and eating disorder symptom severity (coefficient = −0.268, SE = 0.13, p < 0.05, Cohen’s d = −0.102). Conclusions: Greater control over eating improved MHRQoL and decreased the frequency of binge-eating episodes and eating disorder symptom severity. These positive effects were moderated by being in the HAPIFED group, supporting previous findings of benefits to people’s mental health through participation in the HAPIFED trial. Full article

Background: Within recent years, there has been a notable lack of research examining the factors associated with adolescent use of anabolic–androgenic steroids (AASs) in Australia, meaning information regarding risk factors of Australian adolescent AAS use is outdated and potentially inaccurate. Methods: To address this omission, the present study examined the prevalence and correlates of adolescent (aged 11 to 19 years) AAS use within the EveryBODY study, a large-scale representative survey of adolescents’ disordered eating behaviours and body image concerns, involving 5071 adolescents across thirteen schools within the Sydney and Newcastle/Hunter region of New South Wales, Australia. Results: A total of 1.1% of adolescents reported lifetime use of AAS to increase muscularity. In univariate analyses, increased prevalence of AAS use was associated with male sex (OR = 5.67), identifying as Aboriginal or Torres Strait Islander (OR = 3.80), identifying as same-sex or questioning sexual attraction (OR = 3.17), higher drive for muscularity (OR = 2.19) and weight/shape concerns in the past month (OR = 1.28), and higher frequency of purging (OR = 1.11) and binge eating (OR = 1.09) in the past month. In multivariate analysis, only drive for muscularity (OR = 2.44) and purging behaviours (OR = 1.10) remained as significant correlates. Finally, adolescents who reported lifetime AAS use also reported feeling significantly higher levels of distress and physical and psychosocial impairment compared to adolescents who reported never having used AAS to increase muscularity. Conclusions: Positive correlations between disordered eating and weight and shape concerns with AAS use suggests that adolescent AAS use may be conceptualised within the spectra of disordered eating among youth. These findings provide clinicians, carers, and educators with prototypical factors that should assist in the screening of adolescent AAS use to facilitate early intervention. Full article

Background/Objectives: Eating disorders (EDs) are complex psychopathological conditions involving dysfunctional eating behaviors, excessive body image concerns, and impaired emotional regulation. Among moral emotions, guilt plays a significant role in ED dynamics, influencing both symptomatology and interpersonal relationships. This study examines specific guilt subtypes (normative and altruistic guilt) using a specific psychometric tool. Methods: Forty-three adults with anorexia nervosa (AN), bulimia nervosa (BN), or binge eating disorder (BED) were recruited from the Eating Disorder Center of the University of Campania “Luigi Vanvitelli” or referred by psychotherapists. Diagnoses followed DSM-5 criteria. Participants completed the Moral Orientation Guilt Scale (MOGS), assessing guilt subtypes, and the Eating Disorder Inventory-2 (EDI-2), measuring ED symptomatology. Spearman’s rank correlation and stepwise multiple regression analyses were used to identify relationships between guilt dimensions and ED-related symptoms. Results: MOGS subscales were positively correlated with ED symptomatology. Normative guilt was significantly associated with binging and purging (ρ = 0.26, p < 0.05), while altruistic guilt predicted higher interpersonal distrust (t = 3.4, p < 0.01). Regression analysis revealed that age negatively influenced interpersonal distrust (t = −2.9, p < 0.01). Conclusions: In the population examined, guilt significantly influences ED symptomatology and interpersonal functioning, with specific dimensions linked to distinct behaviors and traits. Therapeutic interventions targeting guilt may enhance treatment outcomes by addressing ED emotional underpinnings. However, the results should be interpreted with caution due to the small sample size and lack of longitudinal data to establish causality. Further research with larger samples and longitudinal designs is necessary to validate these findings. Full article

Background/Objectives: Anorexia nervosa (AN) has a high mortality rate frequently related to suicidality; however, there are few studies on suicide attempts (SAs) and non-suicidal self-injuries (NSSIs) in adult inpatients with AN. This study aims to describe SA and NSSI prevalence and related clinical and sociodemographic factors in adult inpatients with AN. Methods: We retrospectively analyzed data on 298 inpatients hospitalized between 2014 and 2023. Suicidality and clinical and sociodemographic data were collected by experienced psychiatrists; then, the patients completed a battery of self-report questionnaires investigating eating-related and general psychopathology. Results: A total of 9.7% of the inpatients reported an SA in their lifetime, and 13.4% reported NSSI. The percentages were lower among patients with restricter-type AN (5.6% SA and 6.6% NSSI) and higher among patients with binge–purging AN (18% SA and 27% NSSI). SAs were associated with unemployment, binge–purging AN, personality disorders, and lifetime sexual abuse; NSSIs were correlated with family psychiatric disorders, binge–purging AN, personality disorders, body dissatisfaction, restriction, and eating-related concerns. No differences emerged in the frequency of reported suicidality between patients tested before and after the COVID-19 pandemic. Conclusions: Suicidality is a relevant issue in AN. Many factors in the history of the patients and their eating-related pathologies should be considered as potentially associated with SA and NSSI and carefully assessed. Full article

Introduction: Bulimia nervosa (BN) is a disorder primarily affecting adolescent females, characterized by episodes of binge eating followed by inappropriate compensatory behaviors aimed at preventing weight gain, including self-induced vomiting and the misuse of diuretics, laxatives, and insulin. The precise etiology of BN remains unknown, with factors such as genetics, biological influences, emotional disturbances, societal pressures, and other challenges contributing to its prevalence. First-line treatment typically includes pharmacotherapy, which has shown moderate effectiveness. Neuroimaging evidence suggests that altered brain activity may contribute to the development of BN, making interventions that directly target the brain extremely valuable. One such intervention is repetitive transcranial magnetic stimulation (rTMS), a non-invasive stimulation technique that has been garnering interest in the medical community for many years. Methods: This review explores the use of rTMS in the treatment of BN. Searches were conducted in the PubMed/Medline, ResearchGate, and Cochrane databases. Results: Twelve relevant studies were identified. Analysis of the results from these studies reveals promising findings, particularly regarding key parameters in the pathophysiology of BN. Several studies assessed the impact of rTMS on binge episodes. While some studies did not find significant reductions, most reported decreases in binge eating and purging behaviors, with some cases showing complete remission. Reductions in symptoms of depression and food cravings were also demonstrated. However, results regarding cognitive improvement were mixed. The discussion focused heavily on potential mechanisms of action, including neuromodulation of brain networks, induction of neuroplasticity, impact on serotonergic dysfunction, anti-inflammatory action, and HPA axis modulation. rTMS was found to be a safe intervention with no serious side effects. Conclusions: rTMS in the treatment of BN appears to be a promising intervention that alleviates some symptoms characteristic of the pathophysiology of this disorder. An additional effect is a significant reduction in depressive symptoms. However, despite these findings, further research is required to confirm its effectiveness and elucidate the mechanisms of action. It is also recommended to further investigate the potential mechanisms of action described in this review. Full article

Background: Non-suicidal self-injury (NSSI) and Feeding or Eating Disorders (FEDs) often coexist during adolescence with reciprocal influences on their clinical picture. The present study aimed to identify differences and similarities in the clinical presentation of young patients with both conditions compared to those with the two non-comorbid disorders. Methods: We consecutively recruited forty-five female patients aged between 11 and 18 at our third-level hospital and subdivided them into three groups (NSSI: n = 15; FED: n = 15; NSSI + FED: n = 15). Patients underwent a full clinical assessment. Results: Based on our results, the NSSI + FED group was characterized by higher rates of binging/purging behaviors, greater prevalence of Cyclothymic Disorder, and a more severe clinical presentation compared to the non-comorbid groups. Moreover, higher levels of suicidal ideation were found in the NSSI + FED group. Pharmacological treatment patterns also differed, with SSRI being prescribed more frequently to NSSI + FED patients while mood stabilizers were prescribed more frequently to NSSI ones. A Principal Component Analysis identified four main dimensions: “Body Image” impairment was more pronounced in NSSI + FED patients, indicating negative attitudes towards their own body; “Metacognition” deficits were higher in NSSI than FED. Conclusions: The present study underscores distinctive clinical features in patients with comorbid NSSI and FED, emphasizing the urgent need for tailored intervention strategies focusing on specific symptom domains.

The aim of the present study was to investigate the potential associations between clinical/socio-demographic variables and the presence of purging/binge-eating episodes in eating disorders (EDs). Clinical/socio-demographic variables and psychometric scores were collected. Groups of patients were identified according to the presence or absence of purging or objective binge-eating episodes (OBEs) and compared through t-test and chi-square tests. Binary logistic regression analyses were run. A sample of 51 ED outpatients was recruited. Patients with purging behaviors had a longer duration of untreated illness (DUI) (t = 1.672; p = 0.019) and smoked a higher number of cigarettes/day (t = 1.061; p = 0.030) compared to their counterparts. A lower BMI was associated with purging (OR = 0.881; p = 0.035), and an older age at onset showed a trend towards statistical significance (OR = 1.153; p = 0.061). Patients with OBEs, compared to their counterparts, were older (t = 0.095; p < 0.001), more frequently presented a diagnosis of bulimia or binge-eating disorder (χ² = 26.693; p < 0.001), a longer duration of illness (t = 2.162; p = 0.019), a higher number of hospitalizations (t = 1.301; p = 0.012), and more often received a prescription for pharmacological treatment (χ² = 7.864; OR = 6.000; p = 0.005). A longer duration of the last pharmacological treatment was associated with OBE (OR = 1.569; p = 0.046). In contrast to purging, OBE was associated with a more complicated and severe presentation of ED. A lower BMI and a later age at onset, as well as long-lasting previous pharmacological treatments, may predict the presence of purging/binging. Further research is needed to thoroughly characterize ED features and corroborate our preliminary findings. Full article

Disordered eating behavior differs between the restricting subtype (AN-R) and the binging and purging subtype (AN-BP) of anorexia nervosa (AN). Yet, little is known about how these differences impact fatty acid (FA) dysregulation in AN. To address this question, we analyzed 26 FAs and 7 FA lipogenic enzymes (4 desaturases and 3 elongases) in 96 women: 25 AN-R, 25 AN-BP, and 46 healthy control women. Our goal was to assess subtype-specific patterns. Lauric acid was significantly higher in AN-BP than in AN-R at the fasting timepoint (p = 0.038) and displayed significantly different postprandial changes 2 h after eating. AN-R displayed significantly higher levels of n-3 alpha-linolenic acid, stearidonic acid, eicosapentaenoic acid (EPA), docosapentaenoic acid, and n-6 linoleic acid and gamma-linolenic acid compared to controls. AN-BP showed elevated EPA and saturated lauric acid compared to controls. Higher EPA was associated with elevated anxiety in AN-R (p = 0.035) but was linked to lower anxiety in AN-BP (p = 0.043). These findings suggest distinct disordered eating behaviors in AN subtypes contribute to lipid dysregulation and eating disorder comorbidities. A personalized dietary intervention may improve lipid dysregulation and enhance treatment effectiveness for AN. Full article
