Emotional abuse interacts with borderline personality in adolescent inpatients with binge-purging eating disorders

The maltreated eco-phenotype of eating disorders: A new diagnostic specifier? A systematic review of the evidence and comprehensive description

This systematic review aimed to summarize the evidence on the existence of a distinct phenotypic expression of Eating Disorders (EDs) associated with childhood maltreatment (CM), the so-called maltreated eco-phenotype of EDs. PRISMA standards were followed. Articles providing data about the characteristics of individuals with an ED reporting CM were included. Relevant results were extracted and summarized. A quality assessment was performed. A total of 1207 records were identified and screened, and 97 articles published between 1994 and 2023 were included. Findings revealed distinct biological and clinical features in patients with EDs reporting CM, including neuroanatomical changes, altered stress responses, ghrelin levels, inflammation markers, and gut microbiota composition. Clinically, CM correlated with severer eating behaviors, higher psychiatric comorbidity, impulsivity, emotional dysregulation, and risky behaviors. Additionally, CM was associated with poorer treatment outcomes, especially in general psychopathology and psychiatric comorbidities. This review highlighted the need to move towards an etiologically informed nosography, recognizing CM not merely as a risk factor, but also as an etiologic agent shaping different eco-phenotypic variants of EDs.

Association of Childhood Emotional Maltreatment with Adolescents' Psychopathology: A Systematic Review and Meta-Analysis

Childhood Emotional Maltreatment (CEM) is a significant but under-studied risk factor for impaired mental health, with adolescents being particularly susceptible. This systematic review and meta-analysis, prospectively registered in PROSPERO as CRD42022383005, aims to synthesize the findings of studies investigating the association between CEM and adolescent psychopathology, making it the first attempt to the best of our knowledge. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines, a comprehensive search (PubMed, Scopus, PsycINFO, Science Direct, Embase, and ProQuest) yielded 12,224 studies, from which 72 were included in the qualitative synthesis. The meta-analysis was conducted on 76 effect sizes (ranging from 0.01 to 0.57) extracted from 56 studies. The assessment of publication bias utilized funnel plots, Egger's regression test, and the trim and fill method, if required. Additionally, a predictor analysis investigated the influence of study-level variables on the CEM-psychopathology association. Results revealed a significant positive correlation between CEM and adolescent psychopathology (Pooled association: 0.24-0.41) Furthermore, assessment of publication bias indicated no significant bias. The predictor analysis suggested minimal influence of study-level variables. The study underscores the urgent need to address CEM as a crucial risk factor for adolescent psychopathology. The significant positive correlation between CEM and psychopathological outcomes highlights the detrimental effects of CEM on adolescents. Awareness, prevention efforts, and targeted interventions are essential to mitigate these effects. Further studies with culturally diverse and larger sample sizes are required, with emphasis on methodological rigor, given that most of the identified studies showed a high risk of bias.

Influence of at-risk family interactions on the course of psychiatric care in adolescence

Dysparenting, referring to inappropriate parental attitudes, is a vulnerability factor for mental disorders during adolescence and a therapeutic leverage, yet clinicians lack reliable tools to assess it in daily clinical practice. Moreover, the effect of this dysparenting on the amount of psychiatric care remains unclear. The Family and Care study aims to develop the at-risk family interactions and levers (ARFIL) scale, a comprehensive 30-item clinical scale, and to assess in a cross-sectional design, the impact of these at-risk family interactions on the care of adolescents (n = 425) hospitalized in psychiatry and aged 13-19 years old. Factorial analysis shows that the ARFIL scale consists of three main dimensions associated with cohesion/conflicts, love/hostility, and autonomy/control with good psychometric properties. Multivariate regressions show that the ARFIL intensity score predicts the duration of hospital care, regardless of age, gender, medical severity on admission, assessed by the Global Assessment of Functioning scale, the presence of maltreatment and psychiatric diagnoses. Moreover, the ARFIL diversity score (number of items present regardless of their severity) predicts both the number and duration of hospitalizations. At-risk family interactions are a determining dimension of psychiatric adolescent care, and the ARFIL scale could constitute a valuable tool, not only for holistic evaluation and treatment, but also for prevention.

Psychiatric and medical comorbidities of eating disorders: findings from a rapid review of the literature

BACKGROUND

Eating disorders (EDs) are potentially severe, complex, and life-threatening illnesses. The mortality rate of EDs is significantly elevated compared to other psychiatric conditions, primarily due to medical complications and suicide. The current rapid review aimed to summarise the literature and identify gaps in knowledge relating to any psychiatric and medical comorbidities of eating disorders.

METHODS

This paper forms part of a rapid review) series scoping the evidence base for the field of EDs, conducted to inform the Australian National Eating Disorders Research and Translation Strategy 2021-2031, funded and released by the Australian Government. ScienceDirect, PubMed and Ovid/Medline were searched for English-language studies focused on the psychiatric and medical comorbidities of EDs, published between 2009 and 2021. High-level evidence such as meta-analyses, large population studies and Randomised Control Trials were prioritised.

RESULTS

A total of 202 studies were included in this review, with 58% pertaining to psychiatric comorbidities and 42% to medical comorbidities. For EDs in general, the most prevalent psychiatric comorbidities were anxiety (up to 62%), mood (up to 54%) and substance use and post-traumatic stress disorders (similar comorbidity rates up to 27%). The review also noted associations between specific EDs and non-suicidal self-injury, personality disorders, and neurodevelopmental disorders. EDs were complicated by medical comorbidities across the neuroendocrine, skeletal, nutritional, gastrointestinal, dental, and reproductive systems. Medical comorbidities can precede, occur alongside or emerge as a complication of the ED.

CONCLUSIONS

This review provides a thorough overview of the comorbid psychiatric and medical conditions co-occurring with EDs. High psychiatric and medical comorbidity rates were observed in people with EDs, with comorbidities contributing to increased ED symptom severity, maintenance of some ED behaviours, and poorer functioning as well as treatment outcomes. Early identification and management of psychiatric and medical comorbidities in people with an ED may improve response to treatment and overall outcomes.

Stressful life events among individuals with a history of eating disorders: a case-control comparison

BACKGROUND

Experiencing stressful life events (SLEs) can negatively impact mental health and increase risk for psychiatric disorders including eating disorders (EDs). Previous research has shown that childhood sexual abuse is associated with some EDs, but less is known about the association between other non-sexual SLEs and EDs.

METHOD

A case-control study of individuals with (n = 495, age mean ± SD = 29.1 ± 9.8 years) and without (n = 395, age = 30.2 ± 11.7) self-reported lifetime history of EDs was conducted to compare history of self-reported SLEs. Participants reported history of sexual (e.g., rape, other sexual assault) and non-sexual (e.g., emotional abuse, assault, bereavement) life events using an adaptation of the Stressful Life Events Screening Questionnaire. Individuals with EDs were divided into ED subtypes along the restricting - binge eating/purging spectrum to examine subtype differences. Logistic regressions were conducted for each SLE and ED subtype to obtain odds ratios (ORs). We report p-values corrected for multiple comparisons.

RESULTS

Exposure to any SLE was significantly more common in individuals with EDs than in controls (OR = 2.47, p < .001). Specifically, rape, other sexual assault, and emotional abuse were significantly more common among individuals with a history of binge-eating/purging ED subtypes (ORs = 2.15-3.58, p's < .01) compared with controls. Furthermore, history of life-threatening disease and loss of a close relative/partner/friend were associated with some ED subtypes. The association between SLEs and EDs was stronger for individuals who had experienced multiple SLEs.

CONCLUSION

By investigating a range of different SLEs, we showed that both sexual and non-sexual SLEs were more common in individuals with a history of EDs (binge-eating/purging subtypes) than controls. Results highlight the importance of assessing a variety of past SLEs in risk assessment for different EDs.
