Associations between adverse childhood experiences and clinical characteristics of eating disorders

Early maladaptive schemas mediate the relationship between severe childhood trauma and eating disorder symptoms: evidence from an exploratory study

BACKGROUND

Childhood trauma history has frequently been linked to eating disorders (EDs); nevertheless, the scientific literature calls for extending knowledge regarding mediators between EDs and childhood trauma. This study explored whether ED symptoms and early maladaptive schemas were more severe in ED patients with severe childhood trauma than in ED patients with no/mild childhood trauma and whether early maladaptive schemas mediated the relationship between childhood trauma and ED symptom severity.

METHODS

Data were extracted from the Regional Centre for Eating Disorders registry at the University Hospital of Verona. The extracted data included self-reported data, including the Eating Disorder Inventory-3 score, Young Schema Questionnaire score, Childhood Experience and Experience of Care and Abuse Questionnaire score, and sociodemographic and clinical information on the ED outpatients seeking care. A mediation analysis using the structural equation modeling procedure was conducted.

RESULTS

Forty-two outpatients, 31% of whom exhibited severe childhood trauma, satisfied the criteria for registry data extraction. The severity of ED symptoms, as well as the early maladaptive schemas' scores for emotional deprivation, defectiveness, failure, vulnerability, insufficient self-control, and negativity, were greater in ED outpatients with severe childhood trauma. Furthermore, early maladaptive schemas related to defectiveness, failure, and negativity had a mediating role in the relationship between severe childhood trauma and ED symptom severity.

CONCLUSIONS

This exploratory study provides preliminary evidence about the importance of early maladaptive schemas in the relationship between trauma history and ED psychopathology. In addition, ED symptoms may represent a dysfunctional attempt to avoid unpleasant emotions associated with schema activation. The results support the need to consider early maladaptive schemas in the treatment of traumatized patients with ED symptoms. Study limitations, research and clinical implications are discussed.

Association between childhood maltreatment and obsessive-compulsive disorder comorbid with eating disorders: a cross-sectional study

BACKGROUND

Obsessive-compulsive disorder (OCD) and eating disorders (ED) share common features, including the presence of obsessions and compulsions, and they often co-occur. Additionally, there is a significant comorbidity between ED and childhood traumatic experiences (CTE), as well as between CTE and OCD. Various biological and environmental factors have been proposed to explain the connection between ED, OCD, and CTE. This study explores the link between CTE and the comorbidity of ED and OCD, with the hypothesis that specific types of CTE may increase the risk of developing OCD in individuals with ED.

METHODS

Participants (N = 562) were enrolled at an eating disorder unit in Montpellier, France, between March 2013 and January 2020. The Childhood Trauma Questionnaire (CTQ), Eating Disorder Examination Questionnaire (EDE-Q), and Mini International Neuropsychiatric Interview (MINI) were used to evaluate childhood maltreatment, assess clinical characteristics associated with ED, and categorize participants into two groups: patients with and without OCD.

RESULTS

Bivariate analysis revealed that patients with comorbid ED and OCD had higher EDE-Q scores (p < 0.001), more anxiety disorders (p < 0.001), depressive disorders (p = 0.02), post-traumatic stress disorder (PTSD) (p < 0.001), and a higher incidence of sexual abuse (p < 0.001) and physical neglect (p = 0.04) compared to those without OCD. Multivariate analysis showed that the association between CTE and OCD was influenced by the presence of an anxiety disorder (p = 0.01) and a higher EDE-Q total score (p = 0.03), with a significant association with a history of sexual abuse (p = 0.04).

CONCLUSIONS

This demonstrates that CTE increases the risk of comorbid OCD in ED patients, correlating with more clinically severe ED and a higher likelihood of anxiety disorders.

Analyzing the relationship between individual and cumulative score of adverse childhood experiences (ACEs) with self-reported mental health disorders in Chile

BACKGROUND

Adverse Childhood Experiences (ACEs) are widely recognized as significant predictors of poor mental health in adulthood. Latin America presents several unique challenges regarding ACEs, such as higher prevalence of violence and income and political inequality. However, little is known about this issue from nationally representative samples in the region, particularly in Chile.

OBJECTIVE

This investigation examines the association between individual and cumulative ACE scores and seven self-reported mental health conditions (substance abuse, depression, PTSD, generalized anxiety, suicide ideation, non-suicidal self-harm, and learning disorders) in a representative Chilean urban sample.

METHODS

A representative urban sample of 2101 adult Chileans completed the International Adverse Childhood Experiences Questionnaire (ACE-IQ) and disclosed any prior mental health diagnoses.

RESULTS

Around 40 % of the sample had experienced four or more ACEs in their lifetime. For these individuals, the risk of reporting a mental health disorder was significantly higher. Several logistic regression analyses were conducted to address the associations between ACEs and the seven mental health conditions. Notably, sexual abuse, bullying, and exposure to collective violence were the ACEs most strongly associated with self-reported mental health issues. Additionally, a cumulative ACE score was found to be a significant predictor of having a previous mental health diagnosis.

CONCLUSIONS

We found a significant predictive association between exposure to collective violence and six out of the seven self-reported mental health disorders. Similarly, sexual abuse demonstrated an association with all mental health conditions. Finally, individuals who experienced four or more ACEs had a notably higher chance of reporting a previous mental health diagnosis. We recommend conducting further ACE research in Latin America due to its cultural and contextual singularities.

The correlates of appearance focused self-concept: personality traits, self-concept, sociocultural, and early life experience factors

BACKGROUND

Theory and research indicate that an appearance focused self-concept (i.e., placing overriding importance on physical appearance for self-definition and self-worth) plays a role in the etiology and maintenance of disordered eating and eating disorders. Although the consequences of an appearance focused self-concept are palpable, less is known about its correlates. Accordingly, we examined a range of factors that may characterize appearance focused people, including personality traits (perfectionism, impulsivity, sensation-seeking, hopelessness, and anxiety sensitivity), self-concept (global self-esteem and self-concept clarity), sociocultural (thin-ideal, muscular-ideal, general attractiveness internalizations, and perceived pressure to be thin), and early life experiences (adverse childhood experiences, attachment styles) factors.

METHODS

Female undergraduate university students (N = 568; Mage = 19.58, SDage = 4.24) completed a questionnaire battery that included the Beliefs About Appearance Scale, Depressive Experiences Questionnaire-Self-Criticism-6 Scale, Frost-Multidimensional Perfectionism Scale, the Revised Almost Perfect Scale, Substance Use Risk Profile Scale, Self-Concept Clarity Scale, Rosenberg Self-Esteem Scale, Sociocultural Attitudes Towards Appearance Questionnaire-4 Scale, Adverse Childhood Experiences Questionnaire, Experiences in Close Relationships Scale Short Form, and the Dietary Restraint subscale of the Eating Disorders Examination Questionnaire.

RESULTS

Multiple regression analyses were conducted for each set of factors separately and together. For personality traits, perfectionism, impulsivity, and anxiety sensitivity were uniquely associated with appearance focused self-concept. For self-concept, global self-esteem and self-concept clarity were uniquely associated with appearance focused self-concept. For sociocultural, general attractiveness internalization, thin-ideal internalization, and perceived pressure to be thin were uniquely associated with appearance focused self-concept. For early life experiences, attachment anxiety and avoidance were uniquely associated with appearance focused self-concept. In the combined analysis, the various factors explained 54% of the variance in appearance focused self-concept. Impulsivity, global self-esteem, general attractiveness internalization, and perceived pressure to be thin were uniquely associated with appearance focused self-concept.

CONCLUSIONS

Results for global self-esteem were consistent with prior research. Findings for evaluative concerns perfectionism were inconsistent with prior research. We discuss future research directions to examine the link between evaluative concerns perfectionism and appearance focused self-concept. We also discuss how sociocultural factors (general attractiveness internalization and perceived pressure to be thin) and impulsivity may help cultivate an appearance focused self-concept, advancing knowledge on the characteristics of appearance-focused people.

"Age of traumatic experience as a predictor of distorted body image in patients with eating disorders"

The timing of trauma exposure is a risk factor for the development of psychopathology in adulthood. We aim to assess the presence of adverse life events (ALEs) before age 13 in patients with eating disorders (ED). Specifically, we examined the relationship between exposure to interpersonal trauma before the age of 13 and body image distortion (BID), impulsivity, and perfectionism. We conducted a cross-sectional, retrospective study in which 79 outpatients with ED were consecutively enrolled. Assessment was performed using the Traumatic Life Event Questionnaire, Contour Drawing Rating Scale, and Eating Disorder Inventory. Linear regression models were used to analyze the predictive role of interpersonal trauma before age 13 on BID perfectionism and impulsivity. Seventy-two patients (91.1%) reported ALEs throughout their lives. Patients with trauma before age 13 (55.6%) overestimated their shape. Patients with ED and bulimic symptoms had significantly higher BID levels. Interpersonal trauma predicted higher levels of impulsivity and perfectionism. Experiencing interpersonal ALEs before age 13 may be a risk factor for the development of BID, impulsivity, and perfectionism in adulthood. Body image can be modified during childhood through interventions focused on identifying stressful relationships.

Adverse childhood experiences, low self-esteem, and salient stimulus response in eating disorders

BACKGROUND

Adverse childhood experiences (ACEs) are elevated in individuals with eating disorders (EDs), but how the neurobiology of EDs and ACEs interact is unclear.

METHODS

Women 18-45 years old with anorexia nervosa (AN, n = 38), bulimia nervosa (BN, n = 32), or healthy controls (n = 60) were assessed for ACEs and ED behaviours and performed a taste-conditioning task during brain imaging. Mediation analyses tested relationships between ACE score, self-esteem, and ED behaviours.

RESULTS

ACE scores were elevated in EDs and correlated positively with body mass index (p = 0.001), drive for thinness (p = 0.001), and body dissatisfaction (p = 0.032); low self-esteem mediated the relationship between ACEs and body dissatisfaction, drive for thinness, and bulimia severity. ACE scores correlated negatively (FDR-corrected) with unexpected, salient stimulus receipt in AN (substantia nigra) and BN (anterior cingulate, frontal and insular cortex, ventral striatum, and substantia nigra). When ACE scores were included in the model, unexpected stimulus receipt brain response was elevated in EDs in the anterior cingulate and ventral striatum.

CONCLUSIONS

ACEs attenuate unexpected salient stimulus receipt response, which may be a biological marker for altered valence or hedonic tone perception in EDs. Low self-esteem mediates the relationships between ACEs and ED behaviours. Adverse childhood experiences should be assessed in biological studies, and their effects targeted in treatment.

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.

Childhood Violence, High School Academic Environment, and Adult Alcohol Use Among Latinas and Black Women: A Structural Equation Modeling Study

OBJECTIVE

Young Latinas and Black women drink less than women of other racial/ethnic groups but experience more alcohol-related problems in midlife. This study aims to identify modifiable factors to prevent adult onset of alcohol use disorder (AUD) in this population.

METHODS

Data were collected at six time points as part of the Harlem Longitudinal Development Study from 365 Latinas (47%) and Black (53%) women (mean age at time 1 = 14, standard deviation 1.3). Structural equation modeling was used to test hypothesized pathways from childhood physical and sexual abuse to AUD via depressive mood, anxiety disorders, and somatic complaints in the 20s. We also tested the moderation effect of the high school academic environment by including in the structural equation model two latent variable interaction terms between the school environment and each of the abuse variables.

RESULTS

Childhood physical and sexual abuse was positively associated with depressive mood, anxiety disorders, and somatic complaints when participants were in the 20s. Depressive mood mediated childhood abuse and AUD when women were in the 30s. The high school academic environment attenuated the effect of physical, but not sexual abuse, on depressive mood (β = -0.59, B = -9.38, 95% CI [-14.00, -4.76]), anxiety symptoms (β = -0.61, B = -14.19, 95% CI [-21.76, -6.61]), appetite loss (β = -0.41, B = -10.52, 95% CI [-15.61, -5.42]), and sleeplessness (β = -0.50, B = -9.56, 95% CI [-13.95, -5.17]) in the early 20s.

CONCLUSIONS

Our findings underscore the need to invest in early violence prevention interventions and in education to ensure equitable access to quality, academically oriented, and safe schools.

Few differences in psychiatric comorbidities and treatment response among people with anorexia nervosa and atypical anorexia nervosa

OBJECTIVE

Little is known about how individuals with atypical anorexia nervosa (AN) respond to eating disorder (ED) treatment in a partial hospitalization program (PHP), nor how certain factors such as trauma, childhood abuse, psychiatric comorbidity, and suicidal thoughts and behaviors might contribute to poor treatment outcomes. Thus, the current study (1) compares prevalence of these factors between individuals with AN and atypical AN upon admission to an ED PHP, (2) compares PHP treatment response between groups, and (3) investigates whether experiencing these factors impacts treatment outcomes.

METHOD

We conducted a retrospective chart review of young adults admitted to a PHP with AN (n = 95) and atypical AN (n = 59). Histories of psychiatric comorbidities and adverse childhood experiences were obtained from initial psychiatric evaluations. ED symptoms were assessed at intake and discharge with the Eating Disorder Examination-Questionnaire (EDE-Q).

RESULTS

No significant differences were found at intake in ED symptom severity or prevalence of lifetime trauma, childhood abuse, number of psychiatric diagnoses, or suicidal thoughts and behavior. Symptomatology at discharge also did not differ between groups. Emotional abuse was significantly related to discharge shape and weight overvaluation. No other intake characteristics were significantly related to discharge symptomatology.

DISCUSSION

To our knowledge, this is the first study to compare the prevalence of comorbidities for both AN and atypical AN, as well as differential treatment outcomes for these individuals in a PHP. Results add to growing literature suggesting that, other than weight, AN and atypical AN have few properties that reliably distinguish them from one another.

PUBLIC SIGNIFICANCE

This study adds to a growing body of literature that raises questions about whether anorexia nervosa (AN) and atypical AN are truly different diagnoses. Our findings suggest these two groups present to treatment in a partial hospitalization program (PHP) with similar ED symptoms, as well as prevalence of lifetime trauma, childhood abuse, suicidal thoughts and behavior, and number of psychiatric comorbidities, and demonstrate similar treatment trajectories in PHP.

Early traumatic experiences and the hypothalamus-pituitary-adrenal axis in people with eating disorders: A narrative review

Exposure to trauma during childhood is a non-specific risk factor for psychiatric disorders, including eating disorders (EDs), over the life course. Moreover, an association between stressful life events and the onset/maintenance of EDs has been documented. Therefore, the hypothalamus-pituitary-adrenal (HPA) axis, namely the main component of the endogenous stress response system, has been proposed to be implicated in the pathophysiology of EDs. In this narrative review the current knowledge concerning the effects of early trauma exposure on the HPA axis activity and their putative role in the pathophysiology of EDs will be illustrated. Research findings corroborate the idea that childhood trauma exposure has long-lasting dysregulating effects on the activity of the HPA axis, which may contribute to the biological background of the early trauma-related risk for the development of EDs across the life span. Moreover, literature data support the existence of a "maltreated ecophenotype" in EDs characterized by specific clinic and neuroendocrine features, which may have important implications in treatment programming for such a type of patients.

Childhood maltreatment, alexithymia and eating disorder psychopathology: A mediation model

BACKGROUND

The relationship between childhood maltreatment and eating disorder psychopathology has been under-investigated.

OBJECTIVE

The purpose of this study was to investigate the role of alexithymia in mediating the relationship between childhood maltreatment experiences and eating disorder (ED) symptoms.

PARTICIPANTS AND SETTING

One-hundred-forty-three women with anorexia nervosa, 110 women with bulimia nervosa and 108 healthy women filled in the Eating Disorder Inventory-2, the Childhood Trauma Questionnaire and the Toronto Alexithymia Scale-20 (TAS-20).

METHODS

A mediator path model including childhood trauma types as predictors, the subscales of the TAS-20 as mediators and ED specific symptoms as dependent variables was conducted in individuals with EDs and in healthy women.

RESULTS

In women with EDs emotional abuse was directly associated with body dissatisfaction and was associated to drive to thinness, bulimia and body dissatisfaction through the mediation of difficulties to identify emotions. In healthy women, physical neglect was directly associated to drive to thinness and bulimia, but no significant mediation effect through alexithymia emerged.

CONCLUSION

Impaired emotion recognition mediates the association between childhood emotional abuse and ED symptoms. Individuals with early emotional abuse may experience ED symptoms to manage confused emotional perceptions. Improving emotional understanding and acceptance may be a treatment target in early maltreated individuals with EDs.

Potential applications of Schema Therapy in the treatment of adolescents with anorexia nervosa: a theoretical analysis

Purpose

The main purpose of the article is to present basic theoretical assumptions on Schema Therapy and its hypothetical application among adolescents suffering with anorexia nervosa.

Views

Anorexia nervosa is a very deadly mental disease, more frequently suffered by females than males, with the mean age of onset at approximately 14-15. Studies underline the relatively poor effectiveness of currently applied treatment methods and the need for new approaches that could be recommended for adolescent patients suffering with this disease. The results of studies conducted to date lead to the conclusion that Schema Therapy is a promising approach for this group. It is a transdiagnostic method of work that compiles elements known in other therapeutic approaches, aiming at an increase in the individual's awareness of their feelings and emotional needs, applied both in adolescent and adult groups of patients. Since the symptoms of eating disorders observed in adolescents are strongly connected with family systems it seems reasonable to use treatment techniques that rigorously address the unmet needs and rejected emotions of the individual.

Conclusions

Based on the data published so far it might be hypothesized that the techniques characteristic for Schema Therapy (e.g. imagery rescripting, chairwork, limited reparenting) could be eligible for use with adolescent patients with anorexia nervosa.They address unmet needs, rejected emotions, and early maladaptive schemas that are very frequent in patients with AN. Since the analysis presented provides only hypotheses and the discussion of theoretical aspects, empirical research in this area is needed.

Advancing the Assessment and Treatment of Comorbid Pediatric Chronic Functional Abdominal Pain (CFAP) and Restrictive Eating Disorders

The aim of this review is to heighten awareness of the association between chronic functional abdominal pain (CFAP) and restrictive eating disorders (ED) in adolescents. We describe current diagnostic practices and propose future research efforts to improve the assessment and treatment of comorbid CFAP and restrictive EDs. A narrative review of the literature on CFAP and EDs was performed using PubMed, JSTOR, ScienceDirect, and PsycINFO and the following search terms: 'restrictive eating disorders', 'chronic functional abdominal pain', 'chronic pain' 'treatment' 'diagnosis' and 'adolescents'. Published studies on restrictive EDs and CFAP from May 2008 to March 2023 were included. Ascribable to the overlap in etiology and symptom presentation, adolescents with chronic pain are significantly less likely to have their ED pathology promptly identified by providers compared to adolescents without comorbid chronic pain. This highlights the importance of the time sensitive and accurate identification of EDs in adolescents with CFAP. Overall, assessment methods are limited and EDs take longer to be identified in adolescents with comorbid CFAP. Future efforts should address diagnostic practices in pediatric settings and improve the communication among medical and mental health providers in order to promote the rapid and effective diagnosis and treatment of comorbid CFAP and EDs.

Food addiction and dietary restraint in postpartum women: The role of childhood trauma exposure and postpartum depression

The early postpartum period is a sensitive time for understanding women's high-risk eating (i.e., eating behavior associated with negative health outcomes) given potential long-term eating behavior implications for infants. Food addiction and dietary restraint are two high-risk eating phenotypes associated with long-term negative health outcomes that have been theoretically linked. Yet, no research has considered how much these constructs overlap during the early postpartum period. The present study sought to characterize these two high-risk eating phenotypes in postpartum women to examine whether these are distinct constructs with specific etiologies and to inform future targets of intervention. Women (N = 277) in the early postpartum period reported on high-risk eating, childhood trauma exposure, depression symptoms, and pre-pregnancy weight. Women's height was measured and pre-pregnancy BMI was calculated. We conducted bivariate correlations and path analysis to characterize the relationship between food addiction and dietary restraint, controlling for pre-pregnancy BMI. Results showed that food addiction and dietary restraint were not significantly associated and that women's childhood trauma exposure and postpartum depression were associated with food addiction but not dietary restraint. Sequential mediation revealed that higher levels of childhood trauma exposure were associated with worse postpartum depression and, in turn, greater food addiction during the early postpartum period. Findings suggest that food addiction and dietary restraint have distinct psychosocial predictors and etiological pathways, which suggests important construct validity differences between the two high-risk eating phenotypes. Interventions seeking to address food addiction in postpartum women and mitigate the impact of this high-risk eating phenotype on the next generation may benefit from treating postpartum depression, especially in women with histories of childhood trauma exposure.

Anorexia Nervosa in Juvenile Systemic Lupus Erythematosus (SLE): A Causality Dilemma

Juvenile-onset systemic lupus erythematosus (jSLE) is an autoimmune disorder with multifaceted clinical findings in different organ systems. Neuropsychiatric manifestations affect more than half of SLE patients, and there is increasing evidence that anorexia nervosa (AN), a feeding and eating disorder (FED) characterized by significantly reduced energy intake, is among them. Herein, a review of the literature on the potential association between jSLE and AN was performed. Reported clinical cases were identified, and putative pathophysiological mechanisms were sought that could potentially explain the observed relationship between these two pathological entities. Four reports of isolated cases and a case series including seven patients were identified. In this limited patient pool, the diagnosis of AN preceded that of SLE in the majority of cases, whereas in all cases both entities were diagnosed within a time span of two years. Many explanations for the observed relationships have been proposed. AN has been associated with the stress of chronic disease diagnosis; on the other hand, the chronic inflammation associated with AN may contribute to the development/appearance of SLE. Adverse childhood experiences, concentrations of leptin, shared autoantibodies, and genetic traits appear to be important factors in this well-established interplay. In essence, it seems important to increase clinician awareness of the concomitant development of AN and SLE and invite further research on the subject.

Novel ketamine and zinc treatment for anorexia nervosa and the potential beneficial interactions with the gut microbiome

Anorexia nervosa (AN) is a severe illness with diverse aetiological and maintaining contributors including neurobiological, metabolic, psychological, and social determining factors. In addition to nutritional recovery, multiple psychological and pharmacological therapies and brain-based stimulations have been explored; however, existing treatments have limited efficacy. This paper outlines a neurobiological model of glutamatergic and γ-aminobutyric acid (GABA)-ergic dysfunction, exacerbated by chronic gut microbiome dysbiosis and zinc depletion at a brain and gut level. The gut microbiome is established early in development, and early exposure to stress and adversity contribute to gut microbial disturbance in AN, early dysregulation to glutamatergic and GABAergic networks, interoceptive impairment, and inhibited caloric harvest from food (e.g., zinc malabsorption, competition for zinc ions between gut bacteria and host). Zinc is a key part of glutamatergic and GABAergic networks, and also affects leptin and gut microbial function; systems dysregulated in AN. Low doses of ketamine in conjunction with zinc, could provide an efficacious combination to act on NMDA receptors and normalise glutamatergic, GABAergic and gut function in AN.

The role of discrimination and adverse childhood experiences in disordered eating

BACKGROUND

In clinical research, there has been a call to move beyond individual psychosocial factors towards identifying cultural and social factors that inform mental health. Similar calls have been made in the eating disorders (ED) field underscoring the need to understand larger sociocultural influences on EDs. Discrimination is a social stressor that may influence mental health in similar ways to traumatic or adverse childhood experiences (ACEs). Given the high rates of EDs and discrimination among marginalized groups, it is vital to understand the role of discrimination and ACEs as predictors of ED symptoms in these populations. The aim of this study is to examine how perceived discrimination predicts ED pathology when statistically adjusting for gender, race, and ACEs.

METHODS

The diverse study sample consisted of 331 undergraduate students from a longitudinal cohort study (ages 18-24; 66% female; 35% White/non-Hispanic). Participants completed measures of everyday discrimination, ACEs, and ED pathology.

RESULTS

Following adjustment for multiple statistical comparisons, the frequency of daily discrimination predicted all ED symptoms above and beyond history of ACEs. In follow-up analyses, number of reasons for discrimination predicted cognitive restraint and purging. Differences in ED symptomatology were found based on the reason for discrimination, gender, and race. Specifically, those who experienced weight discrimination endorsed higher scores on all ED symptoms, and those experiencing gender discrimination endorsed higher body dissatisfaction, cognitive restraint, and restriction. People of color endorsed higher restriction, while female participants endorsed higher scores on all ED symptom with the exception of cognitive restraint.

CONCLUSION

Discrimination is a salient risk factor for ED symptoms even when accounting for individuals' history of ACEs. Future research should utilize an intersectional approach to examine how perceived discrimination affects ED pathology over time. (Word count: 234).

Early life influences on the development of food addiction in college attending young adults

PURPOSE

There is little investigation into the causes of food addiction. The aim of this study was to determine the impact of early life influences on the development of food addiction in college-attending young adults aged 18-29.

METHODS

This study utilized a sequential explanatory mixed-methods research design. College-attending young adults were invited to complete an online survey measuring Adverse Childhood Experiences (ACEs), food addiction, depression, anxiety, stress, and demographic information. Correlations between food addiction and the other variables were analyzed and significant variables were placed into a nominal logistic regression model to predict the development of food addiction. Participants who met the criteria for food addiction were invited to participate in interviews to examine their childhood eating environment and when their symptoms emerged. Interviews were transcribed and thematically analyzed. Quantitative analysis was conducted using JMP Pro Version 16.0 and qualitative analysis was conducted using NVIVO Software Version 12.0.

RESULTS

Survey respondents (n = 1645) had an overall 21.9% prevalence of food addiction. Significant correlations were observed between food addiction and ACEs, depression, anxiety, stress, and sex (p < .01 for all). Depression was the only significant predictor of the development of food addiction (OR = 3.33 95% CI 2.19, 5.05). The most common eating environment described by interview participants (n = 36) was an emphasis on diet culture, ideal body image, and restrictive environments. Symptoms frequently emerged after transitioning into college and having the ability to make their own food choices.

CONCLUSION

These results show the impact of early life eating environments and young adulthood mental health on the development of food addiction. These findings contribute to the understanding of underlying causes of food addiction.

Eating disorders and disordered eating in servicemen and women: A narrative review

OBJECTIVE

Eating disorders (EDs) are mental illnesses impacting all aspects of an individual's life. Recent research has examined EDs and disordered-eating behaviors in the military, a population subject to body composition standards, fitness requirements, and extreme stress. The purpose of this narrative review was to investigate ED and disordered-eating prevalence and their risk factors in ROTC (reserve officers' training corps), active-duty, and veteran servicemembers. The secondary purpose was to provide policy recommendations to reduce the burden of these conditions in the military.

METHODS

PubMed and PsycINFO were reviewed for relevant articles. All studies including data on EDs or disordered eating in U.S. active-duty, ROTC, or veteran populations were considered.

RESULTS

Results revealed a high burden of EDs and disordered eating with bulimic- and binge-type behaviors being the most common. Servicemembers exposed to trauma, including military sexual assault, and those with comorbidities like PTSD showed a higher prevalence. Body composition and fitness testing were also associated with a higher risk. Qualitative studies suggest these conditions serve as coping mechanisms for aspects of military life.

CONCLUSIONS

The high prevalence of EDs and disordered eating in the military points toward the importance of identification, treatment, and prevention. Policy change is necessary to protect servicemembers.

Is history of abuse predictive of eating disorders with binge-eating episodes through an effect mediated by impulsivity? A French longitudinal study

BACKGROUND

In recent years, many studies have explored the associations among impulsivity, history of abuse, the emergence of eating disorders with episodes of binge eating (EDBE) and their severity. Nevertheless, factors associated with successful clinical outcomes of EDBE are still unknown. Our study aimed to test the hypothesis that a history of abuse is associated with unsuccessful clinical outcomes of EDBE through an effect mediated by impulsivity.

METHODS

We assessed patients older than 15 years, 3 months with EDBE at inclusion and at 1 year. Recovery was defined as the absence of eating disorders at 1 year. A mediation analysis was performed by means of structural equation modelling.

RESULTS

We included 186 patients in our analyses (54% bulimia nervosa, 29% anorexia nervosa binge eating/purging type and 17% binge-eating disorder); 179 (96%) were female. One-third (n = 63) of patients reported a history of abuse, and recovery was observed for 20% of the sample (n = 38). Contrary to our assumption, a history of abuse was not associated with the absence of recovery of EDBE at 1 year. Factors unfavourable for achieving recovery were anxiety disorders (odds ratio [OR] 0.41), vomiting (OR 0.39), physical hyperactivity (OR 0.29), negative urgency and a lack of perseverance (OR 0.85 for both). Only positive urgency was positively associated with recovery (OR 1.25).

LIMITATIONS

We excluded 219 patients lost to the 1-year follow-up.

CONCLUSION

Our findings may help to deconstruct the empirical belief that traumatic events may interfere with the successful course of treatment for eating disorders. A high level of positive urgency may be associated with more receptivity to care.

Early adversity promotes binge-like eating habits by remodeling a leptin-responsive lateral hypothalamus-brainstem pathway

Early-life trauma (ELT) is a risk factor for binge eating and obesity later in life, yet the neural circuits that underlie this association have not been addressed. Here, we show in mice that downregulation of the leptin receptor (Lepr) in the lateral hypothalamus (LH) and its effect on neural activity is crucial in causing ELT-induced binge-like eating and obesity upon high-fat diet exposure. We also found that the increased activity of Lepr-expressing LH (LHLepr) neurons encodes sustained binge-like eating in ELT mice. Inhibition of LHLepr neurons projecting to the ventrolateral periaqueductal gray normalizes these behavioral features of ELT mice. Furthermore, activation of proenkephalin-expressing ventrolateral periaqueductal gray neurons, which receive inhibitory inputs from LHLepr neurons, rescues ELT-induced maladaptive eating habits. Our results identify a circuit pathway that mediates ELT-induced maladaptive eating and may lead to the identification of novel therapeutic targets for binge eating and obesity.

Child abuse and eating disorder symptoms: Shedding light on the contribution of identification with the aggressor

BACKGROUND

Childhood abuse has been increasingly recognized as a risk factor for eating disorder symptoms. Additionally, it has been demonstrated that childhood abuse may lead to identification with the aggressor, an automatic defensive process, to survive the abuse. Although it has been clinically implied, the role of identification with the aggressor as a potential mechanism underlying the relation between childhood abuse and eating disorder symptoms has not yet been empirically explored.

OBJECTIVE

This study examines the role of identification with the aggressor as mediator in the association between history of childhood abuse and eating disorder symptoms among adults.

PARTICIPANTS AND METHODS

A convenience sample of 198 participants completed self-report questionnaires assessing history of childhood abuse, eating disorder symptoms, and the various facets of identification with the aggressor.

RESULTS

Severity of childhood abuse was significantly associated with shape and weight overevaluation, body dissatisfaction, and binge eating, as well as with all components of identification with the aggressor. In addition, almost all components of identification with the aggressor were significantly associated with eating disorder symptoms. Finally, identifying with the perpetrator's aggression mediated the association between childhood abuse and eating disorder symptoms.

CONCLUSIONS

The findings may contribute to future clinical interventions by illuminating identification with the aggressor as an important aspect in treating eating disorders. Understanding the pervasive effects of identification with the aggressor on survivors' self and their interactions with others may point to the significance of the therapeutic relationship, through which survivors can reprocess and weaken its detrimental effects.

Adverse childhood experiences increase the risk for eating disorders among adolescents

Purpose

Traumatic events often feature prominently in eating disorders. A questionnaire survey to assess the relation of eating disorder risk to the frequency of adverse childhood experiences (ACEs) and the possible association of eating disorder risk with a particular type of ACE was conducted in a community sample of Hungarian adolescents.

Methods

Demographic and anthropometric data, risk for eating disorders (by SCOFF questionnaire), and ACEs (by ACE score calculator) were collected from 432 adolescents aged 12-17 years.

Results

Adolescents who had undergone four or more ACEs were 5.7 times more likely to be in the high eating disorder risk group than those who did not report any ACEs. Cumulative maltreatment showed a greater association with overall risk for eating disorders than cumulative family dysfunction. There is an increased risk of eating disorders from emotional maltreatment (OR = 3.475), physical maltreatment (OR = 3.440), sexual maltreatment (OR = 10.973), and emotional neglect (OR = 3.331). Dysfunctional family circumstances revealed an association with household mental illness (OR = 3.401).

Conclusion

Our study of the connection between eating disorder risk and ACE is the first of its kind in Central and Eastern Europe. Maltreatments had a greater role than family dysfunctions in increasing the risk of eating disorders. Our findings contribute to a more precise understanding of the role that ACEs play in eating disorders. It is important to bring to clinicians' attention the importance of ACEs in the diagnosis and therapy of eating disorders and their potentially fundamental significance for therapy.

Negative childhood events and the development of the anorexic voice: A grounded theory

BACKGROUND

Many individuals diagnosed with anorexia nervosa (AN) describe their disorder as being represented by an internal 'anorexic voice' (AV). Previous studies have identified associations between eating psychopathology and multifarious forms of adverse life experiences.

AIMS

This study explores the relationship between adverse experiences in childhood and the development of the AV.

MATERIALS AND METHODS

Twelve women who had the experience of the AV in the context of a diagnosis of AN took part in semi-structured interviews. The interview data were analysed using a constructivist grounded theory methodology.

RESULTS

Participants recalled feeling unsafe in a variety of relationships and a theory was constructed in which the AV provides a sense of conditional safety, becoming increasingly hostile and belittling when it is disobeyed, revealing similar characteristics to abusers and bullies in childhood.

DISCUSSION

Findings are related to the broader literature on the link between trauma and eating disorders, and to existing theories of internal voices.

CONCLUSIONS

The findings have implications for a trauma-focused approach when working with the AV.

Adverse childhood experiences and binge-eating disorder in early adolescents

BACKGROUND

Adverse childhood experiences (ACEs) are common and linked to negative health outcomes. Previous studies have found associations between ACEs and binge-eating disorder (BED), though they have mainly focused on adults and use cross-sectional data. The objective of this study was to examine the associations between ACEs and BED in a large, national cohort of 9-14-year-old early adolescents in the US.

METHODS

We analyzed prospective cohort data from the Adolescent Brain Cognitive Development (ABCD) Study (N = 10,145, 2016-2020). Logistic regression analyses were used to determine the associations between self-reported ACEs and BED based on the Kiddie Schedule for Affective Disorders and Schizophrenia at two-year follow-up, adjusting for sex, race/ethnicity, baseline household income, parental education, site, and baseline binge-eating disorder.

RESULTS

In the sample, (49% female, 46% racial/ethnic minority), 82.8% of adolescents reported at least one ACE and 1.2% had a diagnosis of BED at two-year follow-up. The mean number of ACEs was higher in those with a diagnosis of BED compared to those without (2.6 ± 0.14 vs 1.7 ± 0.02). The association between number of ACEs and BED in general had a dose-response relationship. One ACE (adjusted odds ratio [aOR] 3.48, 95% confidence interval [CI] 1.11-10.89), two ACEs (aOR 3.88, 95% CI 1.28-11.74), and three or more ACEs (aOR 8.94, 95% CI 3.01-26.54) were all associated with higher odds of BED at two-year follow-up. When stratified by types of ACEs, history of household mental illness (aOR 2.18, 95% 1.31-3.63), household violence (aOR 2.43, 95% CI 1.42-4.15), and criminal household member (aOR 2.14, 95% CI 1.23-3.73) were most associated with BED at two-year follow-up.

CONCLUSIONS

Children and adolescents who have experienced ACEs, particularly household challenges, have higher odds of developing BED. Clinicians may consider screening for ACEs and providing trauma-focused care when evaluating patients for BED.

Mechanisms by which adverse childhood experiences, other traumas and PTSD influence the health and well-being of individuals with eating disorders throughout the life span

BACKGROUND

Multiple published sources from around the world have confirmed an association between an array of adverse childhood experiences (ACEs) and other traumatic events with eating disorders (EDs) and related adverse outcomes, including higher morbidity and mortality.

METHODS

In keeping with this Special Issue's goals, this narrative review focuses on the ACEs pyramid and its purported mechanisms through which child maltreatment and other forms of violence toward human beings influence the health and well-being of individuals who develop EDs throughout the life span. Relevant literature on posttraumatic stress disorder (PTSD) is highlighted when applicable.

RESULTS

At every level of the pyramid, it is shown that EDs interact with each of these proclaimed escalating mechanisms in a bidirectional manner that contributes to the predisposition, precipitation and perpetuation of EDs and related medical and psychiatric comorbidities, which then predispose to early death. The levels and their interactions that are discussed include the contribution of generational embodiment (genetics) and historical trauma (epigenetics), social conditions and local context, the ACEs and other traumas themselves, the resultant disrupted neurodevelopment, subsequent social, emotional and cognitive impairment, the adoption of health risk behaviors, and the development of disease, disability and social problems, all resulting in premature mortality by means of fatal complications and/or suicide.

CONCLUSIONS

The implications of these cascading, evolving, and intertwined perspectives have important implications for the assessment and treatment of EDs using trauma-informed care and trauma-focused integrated treatment approaches. This overview offers multiple opportunities at every level for the palliation and prevention of EDs and other associated trauma-related conditions, including PTSD.

Binge Eating in Patients Pursuing Bariatric Surgery: Understanding Relationships with Food Insecurity and Adverse Childhood Experiences

BACKGROUND

Positive relationships exist between adult food insecurity and binge eating, and between adverse childhood experiences and binge eating. However, the nature of these relationships remains to be determined.

OBJECTIVES

The current study sought to examine the association between binge eating and childhood abuse and/or neglect and household dysfunction and to explore whether the strength of the relationship between adverse childhood experiences and binge eating differs across levels of food insecurity in patients seeking bariatric surgery.

SETTING

University Hospital in the Appalachian region of United States.

METHODS

A total of 366 adults seeking bariatric surgery completed validated questionnaires as a component of a routine psychological evaluation prior to surgery.

RESULTS

Only childhood experiences of abuse and/or neglect were positively related to adult binge eating, r(363) = .13, P = .011. Food insecurity moderated the relationship between adverse childhood experiences and binge eating, F(4, 358) = 242.98, P < .001, such that the relationship was stronger for individuals who endorsed the presence of both food insecurity and adverse childhood experiences (M = 15.90; standard deviation [SD] = 8.38), relative to individuals who endorsed the absence of both food insecurity and adverse childhood experiences (M = 11.19; SD = 7.91; Tukey P = .005; d = .58).

CONCLUSIONS

Food insecurity strengthens the relationship between adverse childhood experiences and adult binge eating. Results suggest that healthcare providers should include assessments of both adverse childhood experiences and food insecurity to identify patients who may be at risk for disordered eating prior to surgery, as these individuals may require additional interventions to address binge eating and related factors.

Eating disorders among middle school students in a Chinese population: Prevalence and associated clinical correlates

INTRODUCTION

Eating disorders are regarded to be associated with many psychological and behavioral problems. Moreover, adolescence has been reported to be the key period for developing eating habits, and eating disorders typically emerge in adolescence and early adulthood. This study aimed to investigate the prevalence of eating disorders and explore the associated factors among adolescents in Hunan province, China METHODS: A total of 1610 middle school students from Hunan province, China, were enrolled in this study. The participants were aged from 11 to 16 years old. The following data were collected: demographic variables, Body Mass Index (BMI), suicidal behaviors, non-suicidal self-injury, depression, anxiety, stress (depression - anxiety - stress scale, DASS-21), childhood trauma (Childhood Trauma Questionnaire, CTQ), symptoms of social anxiety (Social Anxiety Scale-Adolescents, SAS-A), and eating problems (Eating Attitudes Test, EAT-26).

RESULTS

The estimated prevalence of eating disorders was 8.9%. Compared with participants without eating disorders, participants with eating disorders were more likely to be at a younger age, obese and overweight, and have a history of non-suicidal self-injury, suicidal ideation, suicidal plans, suicide attempts, emotional abuse, physical abuse, emotional neglect, and physical neglect; more likely to experience stress, anxiety or depression as well as have high scores of social avoidance and distress related to general social contexts. Anxiety, emotional neglect, physical neglect, obesity, and overweight were still significant in the binary logistic regression model after controlling for confounding factors. Additionally, younger age, emotional abuse, physical abuse, stress, anxiety, depression, social avoidance, and distress related to general social contexts were significantly correlated with the EAT-26 scores in correlation analysis CONCLUSIONS: Eating disorders are quite common among middle school students. Moreover, eating disorders are associated with younger age, non-suicidal self-injury, suicidal ideation, suicide attempts, stress, anxiety, depression, emotional abuse, physical abuse, emotional neglect, physical neglect, social avoidance, and distress related to general social contents and BMI. This study provides a reference for school counselors and clinicians in the prevention and treatment of eating disorders.

Eating disorder risk identification through embedded electronic medical record prompting

Objective: To evaluate whether the use of electronic medical record (EMR) to prompt universal eating disorder screening with a short questionnaire improved risk detection in a college gynecology clinic. Design: Data obtained via a convenience sample of patients accessing a university health clinic. Clinicians were prompted with the SCOFF tool, a 5-item questionnaire for eating disorder risk with sensitivity of 87.5% and specificity of 95%. Participants: 111 Female-identified patients, ages 18-37. Methods: Clinicians assessed eating disorder symptoms via EMR prompting. Comparison of risk identification from the previous year, in which patients were not universally screened, was conducted via EMR review. Results: Findings showed improved risk identification compared with previous year's symptom-only identification (p = .0047). Conclusion: The SCOFF tool, combined with EMR prompting, can improve eating disorder risk detection.

Fournir aux professionnels des soins primaires un aperçu actualisé du trouble de l’accès hyperphagique (TAH), qui comporte des recommandations pertinentes.

Qualité des données

Une recension a été effectuée dans PubMed, PsycInfo et Google Scholar, sans restrictions temporelles, à l’aide des expressions clés en anglais binge eating disorder, treatment, review, guidelines, psychotherapy, primary care et pharmacotherapy. Le niveau des données probantes pour toutes les recommandations varie de I à III.

Message principal

Le trouble de l’accès hyperphagique est associé à une grande détresse et à une incapacité considérable chez le patient, ainsi qu’à des comorbidités médicales et psychiatriques; il a été ajouté dans la 5e édition du Manuel diagnostique et statistique des troubles mentaux, en 2013. Les médecins de soins primaires sont bien placés pour le dépistage, le diagnostic et l’amorce du traitement du TAH. Une approche par étapes du traitement commence par un développement personnel guidé, suivi par l’ajout ou le changement de la pharmacothérapie, ou par une psychothérapie individuelle, au besoin. Les psychothérapies dont l’efficacité est le plus corroborée par la recherche sont la thérapie cognitivo-comportementale, la thérapie interpersonnelle et la thérapie comportementale dialectique.

Conclusion

Cet aperçu présente des conseils sur le dépistage, le diagnostic et les approches thérapeutiques fondés sur les données probantes actuellement disponibles, de même les avis d’un groupe diversifié d’experts, pour aider à orienter les cliniciens lorsque les données probantes sont limitées.

[Not Available]

Objective

To provide an updated overview of binge eating disorder (BED) that includes recommendations relevant for primary care practitioners.

Quality of evidence

PubMed, Google Scholar, and PsycInfo were searched with no time restriction using the subject headings binge eating disorder, treatment, review, guidelines, psychotherapy, primary care, and pharmacotherapy. Levels of evidence for all treatment recommendations ranged from I to III.

Main message

Binge eating disorder is associated with considerable patient distress and impairment, as well as medical and psychiatric comorbidities, and was added to the Diagnostic and Statistical Manual of Mental Disorders, 5th edition, in 2013. Primary care practitioners are well suited to screen, diagnose, and initiate treatment for BED. A stepped-care approach to treatment starts with guided self-help, adding or moving to pharmacotherapy or individual psychotherapy as needed. The psychotherapies with the most research support include cognitive behaviour therapy, interpersonal therapy, and dialectical behaviour therapy. In terms of pharmacotherapy, evidence supports the use of lisdexamfetamine, antidepressant medications, and anticonvulsant medications.

Conclusion

This overview provides guidance on screening, diagnosis, and treatment approaches based on the currently available evidence, as well as expert opinions of a diverse group of experts to help guide clinicians where evidence is limited.

Adverse childhood experiences among adults with eating disorders: comparison to a nationally representative sample and identification of trauma

BACKGROUND

Adverse childhood experiences (ACEs) are prevalent, impact long-term physical and mental health, and are associated with eating disorders (EDs) in adulthood. The primary objectives of the current study were: (1) to examine and compare ACEs between two samples: treatment-seeking adults, and a nationally representative sample of adults, (2) to characterize ACEs items and total scores across demographic and diagnostic information in adults seeking treatment for an ED, (3) to statistically classify ACEs profiles using latent class analysis, and (4) to examine associations between ACEs profiles and diagnosis.

METHODS

This cross-sectional study assessed patients with a DSM-5 ED receiving treatment between October 2018 and April 2020 at the inpatient, residential, or partial hospitalization levels of care at one of two private ED treatment facilities. ACEs were assessed with the Adverse Childhood Experiences Survey at admission. Generalized linear models and Welch's t-tests were used to compare ACEs in the current sample with national estimates. A latent class analysis was conducted to examine subgroups of ACEs responses, and differences in these classes by ED diagnoses were examined with multinomial logistic regression.

RESULTS

Patients with EDs had significantly higher ACEs scores (M = 1.95, SD = 1.90) than the nationally representative sample (M = 1.57, SD = 4.72; t = 6.42, p < .001). Within patients with EDs, four latent classes of ACEs item endorsement were identified. Patients with other specified feeding or eating disorder (OSFED) and binge eating disorder (BED) were more likely to fall into the "Household ACEs" and "Abuse ACEs" groups, respectively, compared to anorexia nervosa-restricting subtype (AN-R).

CONCLUSIONS

Patients with EDs reported more ACEs than the nationally representative sample, and differences in total ACEs and latent class membership were found across ED diagnoses. The current study can inform the development of trauma-informed care for patients with EDs.

Limitations of the protective measure theory in explaining the role of childhood sexual abuse in eating disorders, addictions, and obesity: an updated model with emphasis on biological embedding

In addition to its immediate negative consequences, childhood sexual abuse is associated with lifelong deleterious mental and physical health outcomes. This review employs a biopsychosocial perspective to better understand pathways from childhood sexual abuse to eating disorders, food and drug addictions, and obesity across the life course. Guided by an updated conceptual model, this review delineates how the biological embedding of childhood sexual abuse triggers a cascade of interrelated conditions that often result in failed attempts at weight suppression and eventually obesity. Such biological embedding involves pathways such as inflammation, allostatic load, reward sensitivity, activation of the hypothalamic-pituitary-adrenal axis, epigenetics, and structural and functional changes in the brain. These pathways are in turn theorized to lead to food addiction, substance use disorder, and eating disorders-each with potential pathways toward obesity over time. Predisposing factors to childhood sexual abuse including gender, culture, and age are discussed. This model calls into question the longstanding "protective measure" theory that purports individuals exposed to sexual abuse will deliberately or subconsciously gain weight in attempt to prevent future victimization. A more comprehensive understanding of the mechanisms by which childhood sexual abuse becomes biologically embedded may help clinicians and survivors normalize and/or address disordered eating and weight-related outcomes, as well as identify intervention strategies.Level of evidence: Level V: opinions of respected authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees.

Childhood Maltreatment and Eating Disorders: A Prospective Investigation

OBJECTIVES

To determine whether childhood maltreatment is a risk factor for two eating disorders (anorexia nervosa and bulimia nervosa) using objective and subjective case definitions.

METHODS

Using a prospective cohorts design, children with documented cases of physical abuse, sexual abuse, and neglect (ages 0-11) from 1967 to 1971 in a Midwestern metropolitan county area were matched on age, race, sex, and approximate family socioeconomic status with non-maltreated children. Both groups were followed up. Retrospective self-reports about childhood maltreatment were collected at age 29. DSM-IV anorexia nervosa (AN) and bulimia nervosa (BN) disorders were assessed at age 41 (N = 807). Logistic and linear regression results are reported.

RESULTS

Using documented cases, childhood maltreatment was not a significant risk factor for AN or BN diagnoses or symptoms in adulthood. However, adults who retrospectively reported any maltreatment and physical and sexual abuse reported significantly more symptoms of AN than those who did not.

CONCLUSIONS

The prediction that childhood maltreatment is a risk factor for anorexia nervosa and bulimia nervosa was partially supported in this longitudinal study. While misattribution of cases might have occurred, these results suggest that researchers and clinicians should use caution in drawing inferences about these relationships and designing interventions.

The connection between childhood maltreatment and eating disorder psychopathology: a network analysis study in people with bulimia nervosa and with binge eating disorder

PURPOSE

Childhood maltreatment (CM) experiences are associated with heightened risk of Eating disorders (EDs). The psychopathological pathways promoting this association in people with Bulimia nervosa (BN) and in those with Binge eating disorder (BED) are under-investigated.

METHODS

One hundred and eighty-one people with BN and 144 with BED filled in the Eating Disorder Inventory-2, to measure ED psychopathology, and the Childhood Trauma Questionnaire, to assess their early traumatic experiences. Network analysis was conducted to investigate the interplay between those variables. The shortest pathways function was employed to investigate the shortest out of all routes conveying the association between CM and ED-specific symptoms.

RESULTS

In both people with BN and with BED, all CM types were connected to the ED psychopathology through the emotional abuse node. The association between emotional abuse and ED-specific symptoms (bulimia and body dissatisfaction) differed in the two groups: in people with BN, it included ineffectiveness, while in people with BED, it involved impulsivity. Interoceptive awareness, an indirect measure of emotion regulation, was included in these pathways in both groups.

CONCLUSION

In the light of literature showing that emotional abuse has a connecting role between CM and ED psychopathology also in anorexia nervosa, the present findings support the idea that emotional abuse conveys such association in all the main ED diagnoses. Ineffectiveness and impulsivity may represent the specific psychopathological dimensions connected to emotional abuse and promoting the maintenance of ED-specific symptoms in BN and in BED, respectively. These findings are worth of attention by clinicians.

LEVEL OF EVIDENCE

Level III: evidence obtained from well-designed cohort or case-control analytic studies.

Adverse childhood experiences among a treatment-seeking sample of adults with eating disorders

OBJECTIVE

The purpose of the current study was to examine the prevalence of adverse childhood experiences (ACEs) among adults with eating disorders (EDs), to assess whether experiencing a greater number of ACEs is associated with more severe ED psychopathology, and to determine whether ACEs predict treatment outcome.

METHOD

Participants were 1819 patients (88.5% female, ages 18-72) admitted to one of two treatment facilities at inpatient, residential, or partial hospitalisation levels of care. The Adverse Childhood Experiences Survey and the Eating Pathology Symptom Inventory (EPSI) were completed at admission and the EPSI at discharge.

RESULTS

Female patients reported higher ACEs than males (p = 0.03), and all diagnoses except avoidant/restrictive food intake disorder had significantly higher ACEs than patients with anorexia nervosa-restricting type (AN-R) (p's < 0.01). Across diagnoses, higher ACEs were associated with decreases in binge eating scores during treatment, but were not associated with changes in purging or restricting. Within diagnoses, higher ACEs scores were associated with decreases in purging for patients with AN-R and increases in purging for patients with binge eating disorder.

CONCLUSIONS

Results partially supported the hypothesis that higher ACEs would be associated with more severe ED psychopathology.

Using phenome-wide association studies and the SF-12 quality of life metric to identify profound consequences of adverse childhood experiences on adult mental and physical health in a Northern Nevadan population

In this research, we examine and identify the implications of Adverse Childhood Experiences (ACEs) on a range of health outcomes, with particular focus on a number of mental health disorders. Many previous studies observed that traumatic childhood events are linked to long-term adult diseases using the standard Adverse Childhood Experience Questionnaire. The study cohort was derived from the Healthy Nevada Project, a volunteer-based population health study in which each adult participant is invited to take a retrospective questionnaire that includes the Adverse Childhood Experience Questionnaire, the 12-item Short Form Survey measuring quality of life, and self-reported incidence of nine mental disorders. Using participant's cross-referenced electronic health records, a phenome-wide association analysis of 1,703 phenotypes and the incidence of ACEs examined links between traumatic events in childhood and adult disease. These analyses showed that many mental disorders were significantly associated with ACEs in a dose-response manner. Similarly, a dose response between ACEs and obesity, chronic pain, migraine, and other physical phenotypes was identified. An examination of the prevalence of self-reported mental disorders and incidence of ACEs showed a positive relationship. Furthermore, participants with less adverse childhood events experienced a higher quality of life, both physically and mentally. The whole-phenotype approach confirms that ACEs are linked with many negative adult physical and mental health outcomes. With the nationwide prevalence of ACEs as high as 67%, these findings suggest a need for new public health resources: ACE-specific interventions and early childhood screenings.

Adverse childhood experiences as risk factors for recurrent admissions in young psychiatric inpatients

BACKGROUND

Patients who require psychiatric inpatient treatment early in life are a particularly at-risk population. Factors such as adverse childhood experiences (ACEs) are, however, not well studied in those requiring psychiatric inpatient treatment during both childhood or adolescence and adulthood. Thus, the aim of the current study was to investigate, in young adult inpatients, the risk factors for prior admissions in Child and Adolescent Psychiatry, with a focus on ACEs.

MATERIALS AND METHODS

An explorative population-based systematic chart investigation of psychiatric inpatients aged 18-25 was conducted at the University Hospital Tulln, Austria. Data analysis was done with descriptive methods and Pearson's chi- squared-, Fisher's exact-, Mann-Whitney-U-tests and predictive logistic regression models.

RESULTS

The sample comprised 390 inpatients (51.8% female), with an average age of 20 years at first psychiatric hospital admission. Those with a former child and adolescent psychiatry inpatient treatment (10.3%) were predominantly female (77.5%). Their number of documented ACEs was increased compared to those without former child and adolescent psychiatry admissions (2 vs 1.1), with up to twice as many experiences of family dysfunction, neglect or abuse. Sexual abuse (OR: 3.0), having been an adopted or fostered child (OR: 4.5), and female sex (OR: 3.0) were identified as main risk factors. Furthermore, former child and adolescent psychiatry inpatients suffered from higher rates of psychosomatic or personality disorders, comorbidities and functional impairment, and were readmitted twice as often in young adulthood.

CONCLUSION

Young adult inpatients with reoccurring psychiatric inpatient treatments have increased rates of severe ACEs. Thus, special attention should be given to identifying ACEs, evaluating needs for psychosocial support and therapy, and meeting these needs after discharge.

Adverse Childhood Experiences and Weight Stigma: Co-Occurrence and Associations with Psychological Well-Being

Prior research has demonstrated that individuals with a higher body weight (i.e., obesity) have a relatively high incidence of adverse childhood experiences (ACEs) (e.g., abuse, neglect). Individuals with obesity are also susceptible to experiencing and internalizing weight stigma. Negative physical and mental health consequences have been associated with both ACEs and weight stigma, yet the interplay between these factors has not been explored. The current study examined ACEs in a sample of 105 treatment-seeking adults with obesity who all reported having experienced and internalized weight stigma (90.5% women, 70.5% non-Hispanic White, mean age=49.1 years). The study aimed to 1) provide a descriptive overview of rates of ACEs in this unique sample of adults with potentially high psychological vulnerability and 2) assess associations between ACEs, weight stigma, and psychological well-being. Over three-fourths of participants (76.2%) reported experiencing at least one ACE. The total number of ACEs was significantly associated with more frequent experiences of and greater distress about weight stigma during childhood, as well as higher current perceived stress. Experiencing weight stigma for the first time in childhood was also associated with more reported ACEs. ACEs of abuse were associated with more lifetime reported experiences of weight stigma and greater internalization, use of eating as a strategy to cope with weight stigma, and higher perceived stress. These findings have implications for early identification of and tailored interventions for individuals who have experienced adverse events and weight stigma at a young age.

Childhood Memories in Eating Disorders: An Explorative Study Using Diagnostic Imagery

Together with socio-cultural components, the family environment and early parent-child interactions play a role in the development of eating disorders. The aim of this study was to explore the nature of early parent-daughter relationships in a sample of 49 female inpatients with an eating disorder. To acquire a detailed image description of the childhood experiences of the patient, we used diagnostic imagery, a schema therapy-derived experiential technique. This procedure allows exploring specific contents within the childhood memory (i.e., emotions and unmet core needs), bypassing rational control, commonly active during direct verbal questioning. Additionally, patients completed self-report measures to assess for eating disorder severity, general psychopathology, and individual and parental schemas pervasiveness. Finally, we explored possible differences in the diagnostic imagery content and self-report measures in two subgroups of patients with anorexia nervosa and bulimia nervosa. The results showed that the most frequently reported unmet needs within the childhood memories of patients were those of safety/protection, care/nurturance, and emotional expression, referred specifically to the maternal figure. Overall, mothers were described as more abandoning, but at the same time particularly enmeshed in the relationship with their daughters. Conversely, patients perceived their fathers as more emotionally inhibited and neglecting. Imagery-based techniques might represent a powerful tool to explore the nature of early life experiences in eating disorders, allowing a more detailed case conceptualization and addressing intervention on early-life vulnerability aspects in disorder treatment.

Risk factors for eating disorders: an umbrella review of published meta-analyses

Objective:

To grade the evidence about risk factors for eating disorders (anorexia nervosa, bulimia nervosa, and binge eating disorder) with an umbrella review approach.

Methods:

This was a systematic review of observational studies on risk factors for eating disorders published in PubMed/PsycInfo/Embase until December 11th, 2019. We recalculated random-effect meta-analyses, heterogeneity, small-study effect, excess significance bias and 95% prediction intervals, grading significant evidence (p < 0.05) from convincing to weak according to established criteria. Quality was assessed with the Assessment of Multiple Systematic Reviews 2 (AMSTAR-2) tool.

Results:

Of 2,197 meta-analyses, nine were included, providing evidence on 50 risk factors, 29,272 subjects with eating disorders, and 1,679,385 controls. Although no association was supported by convincing evidence, highly suggestive evidence supported the association between childhood sexual abuse and bulimia nervosa (k = 29, 1,103 cases with eating disorders, 8,496 controls, OR, 2.73, 95%CI 1.96-3.79, p = 2.1 x 10-9, AMSTAR-2 moderate quality) and between appearance-related teasing victimization and any eating disorder (k = 10, 1,341 cases with eating disorders, 3,295 controls, OR 2.91, 95%CI 2.05-4.12, p = 1.8x10-9, AMSTAR-2 moderate quality). Suggestive, weak, or no evidence supported 11, 29, and 8 associations, respectively.

Conclusions:

The most credible evidence indicates that early traumatic and stressful events are risk factors for eating disorders. Larger collaborative prospective cohort studies are needed to identify risk factors for eating disorders, particularly anorexia nervosa.

Ghrelin as a possible biomarker and maintaining factor in patients with eating disorders reporting childhood traumatic experiences

OBJECTIVE

The recent conceptualization of ghrelin as a stress hormone suggested that its chronic alterations may have a role in maintaining overeating behaviors in subjects with eating disorders (EDs) reporting childhood traumatic experiences. The aim of this study was to investigate the alterations of ghrelin levels in patients with EDs, their associations with early trauma, binge and emotional eating, and possible moderation/mediation models.

METHOD

Sixty-four patients with EDs and 42 healthy controls (HCs) had their plasma ghrelin levels measured and completed questionnaires evaluating general and ED-specific psychopathology, emotional eating, and childhood traumatic experiences.

RESULTS

Participants with anorexia nervosa had higher ghrelin levels than HCs in body mass index (BMI)-adjusted comparisons. Moreover, patients reporting a history of childhood trauma had higher ghrelin levels. Childhood sexual abuse (CSA), BMI, and self-induced vomiting were independent predictors of ghrelin levels. Moderation analyses showed that ghrelin levels were associated with binge and emotional eating only for higher levels of childhood trauma. Elevated ghrelin was a significant mediator for the association of CSA with binge eating.

CONCLUSIONS

These results support the hypothesis that chronic alterations in ghrelin levels following childhood traumatic experiences could represent a neurobiological maintaining factor of pathological overeating behaviors in EDs.

Childhood maltreatment and disordered eating attitudes and behaviors in adult men and women:Findings from project EAT

This study examined gender differences in the association between childhood maltreatment and disordered eating attitudes and behaviors in adulthood. Data were derived from 1647 adults (ages 27-33) participating in a population-based, longitudinal study (Project EAT-IV: Eating Among Teens and Young Adults, 1998-2016). Childhood maltreatment (sexual abuse, physical abuse, emotional abuse, emotional neglect) and disordered eating attitudes and behaviors (overeating, binge eating, extreme weight control behaviors, unhealthy weight control behaviors, chronic dieting, weight and shape concerns) were assessed. Relative risk regression models were used to examine whether childhood maltreatment was related to individual disordered eating attitudes and behaviors. Gender differences in these associations were explored. A history of any childhood maltreatment was associated with more than 60% greater risk for chronic dieting and overeating, with additional associations found for binge eating, weight and shape concerns, and unhealthy weight control behaviors. All types of abuse and neglect were associated with at least one type of disordered eating outcome. Examination of the point estimates indicated that emotional neglect was most consistently related to higher risk for disordered eating attitudes and behaviors. Although there were no statistically significant gender differences in the association between childhood maltreatment and disordered eating attitudes and behaviors, the patterning of these effects highlighted unique qualitative similarities and differences in these relationships between men and women. Taken together, these findings implicate childhood maltreatment, particularly emotional neglect, as a meaningful risk factor for problematic eating outcomes in both men and women during adulthood.

Academy of Nutrition and Dietetics: Revised 2020 Standards of Practice and Standards of Professional Performance for Registered Dietitian Nutritionists (Competent, Proficient, and Expert) in Eating Disorders

Eating disorders (ED) are complex mental illnesses and are not a result of personal choice. Full recovery from an ED is possible. The severity and inherent lethality of an ED is undisputed, and the role of the registered dietitian nutritionist (RDN) is essential. Clinical symptomology presents at varying developmental milestones and is perpetuated through a sociocultural evaluation of beauty and drive for ascetic idealism. ED are globally prevalent in 4.4% of the population aged 5 to 17 years, yet affect individuals across the entire lifespan, including all cultures and genders. The Behavioral Health Nutrition Dietetic Practice Group, along with the Academy of Nutrition and Dietetics Quality Management Committee, revised the Standards of Practice (SOP) and Standards of Professional Performance (SOPP) for RDNs in Eating Disorders. Including the RDN in ED treatment is vital for all levels of care. The RDN must be perceptive to negative symptoms indicative of psychological triggers when exploring food belief systems, patterns of disinhibition, and nutrition misinformation with clients. Through a conscious awareness of medical, psychological, and behavioral strategies, the implementation of the SOP and SOPP supports a dynamic and holistic view of ED treatment by the RDN. The SOP and SOPP are complementary resources for RDNs and are intended to be used as self-evaluation tools for assuring competent practice in ED and for determining potential education, training, supervision, and mentorship needs for advancement to a higher practice level in a variety of settings.

Suicide attempts among people with eating disorders and adverse childhood experiences: Results from a nationally representative sample of adults

OBJECTIVE

People with eating disorders (EDs) have elevated rates of suicide attempts. A need exists to identify factors that help predict which people with EDs might be at greater risk for suicidal behavior. Adverse childhood experiences (ACEs) are associated with both EDs and with suicide attempts. Thus, the current study examined whether having histories of ACEs and EDs augments lifetime risk for suicide attempts.

METHOD

This study included 36,146 adult participants in the National Epidemiologic Survey on Alcohol and Related Conditions-III who completed structured diagnostic interviews and answered questions regarding ACEs and suicide attempts. Weighted means, frequencies, and cross-tabulations were computed for prevalence of ACEs and suicide attempts by ED diagnosis. Multiple logistic regression was used to compare risk of lifetime suicide attempts by ED diagnosis and ACE history.

RESULTS

Prevalence of ACEs among people with EDs was 54.1-67.8%. ACE history and ED diagnosis were associated with elevated odds of experiencing a lifetime suicide attempt (AORs = 4.64-6.45 and 3.20-4.06, respectively). There was no ACE history-by-ED interaction on risk of suicide attempt, regardless of forms of EDs.

DISCUSSION

ACEs are common among people with EDs and associated significantly with suicide attempts, but ACEs and EDs do not appear to interact to augment risk for suicide attempts. Considering ACE exposure in theoretical models of suicidal behavior in people with and without EDs and in suicide risk assessment and management with people with EDs may prove useful.

How often were you traumatized? Reconceptualizing adverse childhood experiences for sexual and gender minorities

INTRODUCTION

The manifold consequences of adverse childhood experiences (ACEs) are well-documented. Recent research has demonstrated that sexual and gender minorities (SGMs) typically encounter ACEs more often than cisgender heterosexual individuals. Given the higher exposure rate, the measurement of frequency of exposure to traumatic events may be relevant for SGMs.

METHODS

We changed the response options of the ACEs index from dichotomous to a five-point Likert scale that described frequency of exposure. As part of a larger community-based participatory research study, the Likert ACEs measure was distributed to a large and diverse sample of SGM participants in San Antonio.

RESULTS

A cross-validation design demonstrated that the Likert ACEs scores outperformed the traditional ACEs index in predicting self-reported anxiety and post-traumatic stress disorder. Half of the SGMs in this sample experienced 3 or more ACEs, compared to only 10% of Americans in a nationally representative sample.

LIMITATIONS

These analyses were based on retrospective self-report data instead of structured clinical interviews. Since only the Likert ACEs was administered, we had to assume that any response other than "never" on Likert ACEs corresponded to "yes" on the ACEs Index.

CONCLUSIONS

Future research may assess the utility of the Likert ACEs approach with other minoritized or intersectional populations. For clinical practitioners, these results suggest that a better way to measure ACEs for SGMs is to ask them how often they were exposed, rather than asking whether they were exposed.

Avocado oil (Persea americana) protects SH-SY5Y cells against cytotoxicity triggered by cortisol by the modulation of BDNF, oxidative stress, and apoptosis molecules

Chronic psycho-environmental stress can induce neurological dysfunction due to an increase in cortisol levels. It is possible that some food supplements could attenuate its negative impact, such as avocado oil (AO), which is rich in fatty acids with beneficial effects on the brain. This hypothesis was tested by an in vitro model using undifferentiated neuroblastoma cells (SH-SY5Y) exposed to hydrocortisone (HC), an active cortisol molecule with and without AO-supplementation. Cortisol can induce oxidative stress, apoptosis events, and a lowering effect on brain-derived neurotrophic factor (BDNF), a neurogenic molecule. As AO protective effects on HC-exposed cells could involve these routes, some markers of these routes were compared among neuroblastoma cultures. In the first assay, the range concentrations of HC exposure that trigger cell mortality and range AO-concentrations that could revert the HC effect. AO at all concentrations tested (2-30 µg/ml) did not present a cytotoxic effect on SH-SY5Y cells, whereas HC at 0.3-10 ng/ml had a dose-dependent cytotoxic effect on these cells. From these results, HC at 10 ng/ml and AO at 5 µg/ml were chosen for mechanistic analysis. AO was able to decrease the oxidative molecules; however, both AO- and HC-induced differential and varied gene expression modulation of these enzymes. AO partially reverted the protein and gene expression of apoptotic markers that were higher in HC-exposed cells. AO also increases the BDNF levels, which are lower HC-exposed cultures. The results indicate that AO could be a beneficial supplement in situations where cortisol levels are elevated, including chronic psycho-environmental stress. PRACTICAL APPLICATIONS: Psychological chronic stress that induces high cortisol exposure has been linked to premature aging and decreased healthy life expectancy. Neurobiological models involving cortisol have suggested a neurotoxic effect of this molecule, increasing the risk of psychiatric and other CNTDs. This effect can have a high impact mainly in infants and elderly people. In child abuse situations, chronic cortisol exposure could induce extensive apoptosis events, causing impairment in synaptogenesis. In both age groups, chronic cortisol exposure increased the risk of psychiatric conditions, especially anxiety and major depression. However, it is possible that the negative effects associated with chronic cortisol exposure could be attenuated by some food supplements. This is the case for molecules acquired through diet, such as polyunsaturated fatty acids (PUFAs), including omega-3. As inadequate omega-3 levels in the brain can increase the risk factor for neuropsychiatric disorders, it is possible to infer that some from food supplements, such as avocado oil, could attenuate the neurotoxic effects of chronic cortisol exposure. This hypothesis was tested using an exploratory in vitro protocol, and the results suggested that avocado oil could be used as a cytoprotective food supplement by decreasing the oxidative stress and apoptotic events induced by cortisol.

Associations between adverse childhood experiences and weight, weight control behaviors and quality of life in Veterans seeking weight management services

INTRODUCTION

A neglected area of trauma research with Veterans is the study of Adverse Childhood Experiences (ACEs). The present study aimed to examine the prevalence of ACEs, and to explore relationships between ACEs and measures of weight, eating behaviors and quality of life in weight loss seeking Veterans.

METHODS

Participants were 191 Veterans [mean age 58.9 (SD = 12.8), mean Body Mass Index (BMI) 35.4 (SD = 6.1), 86.9% male, 33.7% racial/ethnic minority] receiving care at VA Connecticut Healthcare System (VA CT) who attended an orientation session of VA's behavioral weight management program. Participants completed a measure of ACEs and measures related to weight, eating and health.

RESULTS

Among completers, 68.6% endorsed at least one ACE. The average number of reported ACEs was 2.2 (SD = 2.5), with 48.7% of Veterans reporting more than one type of ACE. Women were more likely to report any ACE (88.0% vs. 65.6%, p = .025) and reported significantly more ACEs compared to males (4.2 vs. 1.9, p < .001). ACEs were associated with lower physical activity (p = .05), lower quality of life (p's < 0.05), and lower weight-related quality of life (p < .01), but not weight, weight control strategies, binge eating, or alcohol use.

CONCLUSION

ACEs are common among weight loss seeking Veterans, particularly among female Veterans. Findings suggest that there is a high rate of ACEs in Veterans, which are associated with exercise and quality of life outcomes, but not diet and weight outcomes.
