J Affect Disord 2024; 361:684-692. [PMID: 38936703 DOI: 10.1016/j.jad.2024.06.084] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/06/2024] [Revised: 06/20/2024] [Accepted: 06/22/2024] [Indexed: 06/29/2024]
Abstract
OBJECTIVE Internet-Based Cognitive Behavioral Therapy (iCBT) is an innovative modality of cognitive-behavioral intervention that presents a promising therapeutic strategy for individuals diagnosed with binge spectrum eating disorders. This study employed a meta-analysis methodology to assess the clinical effectiveness and acceptability of iCBT. METHODS We conducted searches in databases such as PubMed, Embase, Web of Science, Cochrane Library, and PsycINFO, collecting literature that met the inclusion criteria until August 5, 2023. RESULTS A comprehensive analysis was conducted, encompassing a total of 11 randomized controlled studies that satisfied the predetermined criteria for inclusion. The summary results demonstrated that iCBT could significantly improve the pathological features related to eating in patients with binge spectrum eating disorders and also significantly reduce the frequency of binge episodes. Additionally, iCBT could ameliorate the depressive and anxious emotions of patients with binge spectrum eating disorders and boost their self-esteem. Furthermore, a notable disparity in dropout rates was seen in comparison to the control group. LIMITATION Heterogeneity across studies,limitations of self-assessment scales and potential publication bias. CONCLUSION iCBT can effectively assist patients with binge spectrum eating disorders in improving clinical symptoms. However, it is important to use caution when interpreting the findings of this study, as there are limitations pertaining to the quantity and quality of the included studies.

Abstract
BACKGROUND Immersive Virtual Reality (IVR) has shown promise in the assessment, understanding, and treatment of eating disorders (EDs), providing a dynamic platform for clinical innovation. This scoping review aims to synthesize the recent advancements and applications of IVR in addressing these complex psychological disorders. METHODS This review followed the Preferred Reporting Items for Systematic Reviews and Meta-analysis Protocols, focusing on studies published in the past five years. It included peer-reviewed papers that used IVR for ED assessment, examination, or treatment. A comprehensive database search provided a selection of relevant articles, which were then methodically screened and analyzed. RESULTS Twenty studies met the inclusion criteria, with a primary focus on Anorexia Nervosa (AN), Bulimia Nervosa (BN), and Binge Eating Disorder (BED). The application of IVR was categorized into three areas: assessment, understanding, and treatment. IVR was found to be an effective tool in assessing body image distortions and emotional responses to food, providing insights that are less accessible through traditional methods. Furthermore, IVR offers innovative treatment approaches by facilitating exposure therapy, modifying body-related biases, and enabling emotional regulation through embodied experiences. The studies demonstrate IVR's potential to improve body image accuracy, reduce food-related anxieties, and support behavioral changes in ED patients. CONCLUSION IVR stands out as a transformative technology in the field of EDs, offering comprehensive benefits across diagnostic, therapeutic, and experiential domains. The IVR's ability to simulate the brain's predictive coding mechanisms provides a powerful avenue for delivering embodied, experiential interventions that can help recalibrate distorted body representations and dysfunctional affective predictive models implicated in EDs. Future research should continue to refine these applications, ensuring consistent methodologies and wider clinical trials to fully harness IVR's potential in clinical settings.

Abstract
Binge eating disorder (BED) is the most common specific eating disorder (ED). It is frequently associated with attention deficit hyperactivity disorder (ADHD), depression, bipolar disorder (BD), anxiety disorders, alcohol and nicotine use disorder, and obesity. The aim of this narrative review was to summarize the evidence for the pharmacological treatment of BED and its comorbid disorders. We recommend the ADHD medication lisdexamfetamine (LDX) and the antiepileptic and antimigraine drug topiramate for the pharmacological treatment of BED. However, only LDX is approved for the treatment of BED in some countries. Medications to treat diseases frequently comorbid with BED include atomoxetine and LDX for ADHD; citalopram, fluoxetine, sertraline, duloxetine, and venlafaxine for anxiety disorders and depression; aripiprazole for manic episodes of BD; lamotrigine, lirasidone and lumateperone for depressive episodes of BD; naltrexone for alcohol use disorder; bupropion for nicotine use disorder; and liraglutide, semaglutide, and the combination of bupropion and naltrexone for obesity. As obesity is a frequent health consequence of BED, weight gain-inducing medications, such as the atypical antipsychotics olanzapine or clozapine, the novel antidepressant mirtazapine and tricyclic antidepressants, and the mood stabilizer valproate should be avoided where possible. It is currently unclear whether the novel and promising glucagon, glucose-dependent insulinotropic polypeptide (GIP), and glucagon-like peptide 1 (GLP-1) receptor agonists like tirzepatide and retatrutide help with BED and its comorbidities. However, these compounds have been reported to reduce binge eating in individuals with obesity or overweight.

Abstract
PURPOSE OF REVIEW The Arab world is dealing with modernization and sociocultural changes both associated with eating disorders. The present review provides an update of 'Eating disorders in the Arab world: a literature review', which was published in 2020. RECENT FINDINGS There are 22 recent epidemiological studies on eating disorders in five different countries in the Arab world. A large-scale national mental health survey reported a 12-month eating disorder prevalence of 3.2% and an eating disorder lifetime prevalence of 6.1%. Binge-eating disorder was the most common eating disorder (12-month prevalence = 2.1%, lifetime prevalence = 2.6%), 1.6% was at high risk for binge-eating disorder. Overall, between 23.8 and 34.8% was at high risk for any eating disorder. Body-shape dissatisfaction, a high BMI and separated/widowed/single marital status were associated with eating disorder pathology. SUMMARY Although there is still a lack of studies compared to the western world, the number of epidemiological studies on eating disorders in the Arab world is growing and there is an increase in studies using appropriate assessment-tools and norms. It is recommended to offer specialized treatment and to implement preventive programs.

Abstract
BACKGROUND Psychopathological disorders are often comorbid diagnosis in eating disorders (EDs). We aimed to assess the presence of psychopathological traits and symptoms associated with EDs in an Italian high school adolescent population. METHODS A sample of high school adolescents was enrolled, and demographic and clinical data were collected. Two self-report questionnaires, the Eating Disorder Inventory-3 (EDI-3) and the Questionnaire for the Assessment of Psychopathology in Adolescence (Q-PAD), were administered. RESULTS 548 adolescents (333 F/215 M; 16.89 ± 0.85 years) were included. Symptoms associated with EDs of clinical or high clinical concern were prevalent in a range of individuals, with percentages varying from 26.82% for body dissatisfaction to 51.83% for Interoceptive Deficits. The findings from the Q-PAD assessment indicated the presence of psychological distress, leading to discomfort or challenging situations requiring potential intervention in a percentage of adolescents ranging from 2.93% for psychosocial risks to 23.77% for anxiety. These percentages showed differences between genders (F > M, p < 0.001). Our study also highlighted an association between symptoms of EDs and lifestyle factors within families. We observed correlations between Q-PAD measures and EDI-3 scores, including a positive correlation between Q-PAD and EDI-3 body dissatisfaction (r = 0.7), Q-PAD interpersonal conflicts and EDI-3 interpersonal problems (r = 0.6) and a negative correlation between Q-PAD self-esteem and well-being and EDI-3 ineffectiveness Composite (r=-0.7). CONCLUSIONS a substantial prevalence of ED symptoms and psychological distress among high school adolescents were recorded. These conditions are interrelated, suggesting the importance of addressing them comprehensively. Early detection is essential to improve treatment outcomes and to implement preventive strategies.

Abstract
In the previous literature, specific attention has been paid to investigate autism spectrum symptoms and traits in university students. In this framework, we aimed to evaluate the presence and correlates of autistic traits, hikikomori tendencies, altered eating behaviors, and pathological videogaming in a sample of Italian university students enrolled in bachelor's degree courses. A total of 1192 students were recruited via an online survey and assessed with the Hikikomori Questionnaire-25, the Adult Autism Subthreshold Spectrum Questionnaire, the Eating Attitude test-26, and the Assessment of Internet and Computer Game Addiction. Our results highlighted significant differences in the prevalence of autistic traits, social withdrawal tendencies, altered eating habits, and pathological videogame use in university students based on gender, age, parents' level of instruction, and field of study. A significant effect of the presence of autistic traits and gender on the scores obtained with the other questionnaires was reported. Our results not only support the role of autistic traits as a vulnerability factor for the development of a set of psychopathological conditions but also suggest that gender could modulate this vulnerability, supporting the hypothesis of gender-specific phenotypes in the autism spectrum.

Abstract
PURPOSE OF REVIEW To consolidate recent literature addressing eating disorders and disordered eating behaviors among sexual and gender minority (SGM) adolescents, including but not limited to lesbian, gay, bisexual, transgender, and queer (LGBTQ) adolescents. RECENT FINDINGS Sexual and gender minority adolescents are at heightened vulnerability to eating disorders and disordered eating behaviors compared to their cisgender and heterosexual peers, potentially due to minority stress, gender norms, objectification, and the influence of the media, peers, and parents. We report findings from recent literature on the epidemiology and prevalence, assessment, mental health comorbidity, quality of life and psychosocial functioning, risk and protective factors, and treatment and interventions for eating disorders in sexual and gender minority adolescents. Addressing eating disorders in sexual and gender minority adolescents requires an integrated approach consisting of screening, tailored treatment, and comprehensive support to address intersectional challenges. Gender-affirming and trauma-informed care approaches may be considered.

Abstract
BACKGROUND Cognitive-behavioral therapy (CBT) is an evidence-supported treatment for adolescents with binge-eating disorder (BED). Executive dysfunctions, which are associated with binge eating and elevated body weight in youth, may undermine CBT outcomes by making it difficult for youth to engage with or adhere to treatment, including recalling and/or implementing intervention strategies in real-world contexts. METHODS We assessed 73 adolescents [82.2% female; Mage = 15.0 ± 2.5 year; M baseline standardized body mass index (zBMI) = 1.9 ± 1.0 kg/m2] with BED at baseline, posttreatment, 6-, 12-, and 24-month follow-up. Linear mixed models examined the effects of baseline executive functioning (EF) on loss of control (LOC) eating and weight change following CBT. Linear and logistic regressions probed associations between EF, attendance, and attrition. RESULTS More impulsive decision-making, as reflected in higher baseline scores on the Iowa Gambling Task, predicted better attendance (β = .07; p = .019) and more frequent LOC eating following treatment (β = .12; p = .017). Lower cognitive flexibility, as reflected in lower baseline T-scores on the Comprehensive Trail Making Test complex sequencing index, predicted higher zBMI following treatment (β = -.03; p = .003). Inhibition, concentration, attention, and parent-reported EF behavior symptoms were not associated with outcome, attendance, or attrition. CONCLUSIONS More impulsive decision-making and lower cognitive flexibility were associated with suboptimal response to CBT for BED, although findings should be interpreted with caution in light of the sample size and waitlist control design. Future research should examine whether strengthening EF could improve eating and weight outcomes among adolescents with BED who have lower pre-treatment EF.

Abstract
BACKGROUND Many patients with eating disorders report exercise as a central symptom of their illness-as a way to compensate for food intake, prevent weight-gain, and/or reduce negative affect. Previous findings show associations between maladaptive exercise and more severe eating disorder pathology, higher risk for relapse, other co-morbid symptoms, and worse treatment outcome. METHODS In this study, we included 8252 participants with eating disorders and investigated associations between maladaptive exercise (both lifetime and current) and ED pathology, illness duration, depression, anxiety, self-harm and suicidal ideation, and treatment seeking patterns in individuals with lifetime maladaptive exercise. Participants were included via the Swedish site of the large global study The Eating Disorders Genetics Initiative (EDGI) and completed measures of both lifetime and current symptomatology. RESULTS Results indicate that lifetime maladaptive exercise is associated with higher prevalence of lifetime depression and anxiety and with patients more often receiving treatment, although these results need to be investigated in future studies. Current maladaptive exercise was associated with more severe ED symptoms, and higher levels of depression, anxiety, obsessive-compulsive traits, and suicidal ideation. CONCLUSIONS Our findings point to the complexities of exercise as an eating disorder symptom and the need for clearly assessing and acknowledging this, as well as tailoring interventions to treat this symptom to achieve sustainable recovery.

Abstract
OBJECTIVE We aimed to use real-world data to characterize the burden of psychiatric comorbidities in young people with eating disorders (EDs) relative to peers without EDs. METHOD This retrospective cohort study used a large federated multi-national network of real-time electronic health records. Our cohort consisted of 124,575 people (14,524 people receiving their index, first-ever, ED diagnosis, compared to 110,051 peers without EDs initiating antidepressants). After 1:1 propensity score matching of the two cohorts by pre-existing demographic and clinical characteristics, we used multivariable logistic regression to compute the adjusted odds ratio (aOR) of psychiatric diagnoses arising in the year following the index event (either first ED diagnosis or first antidepressant script). RESULTS Over 50% of people with EDs had prior psychiatric diagnoses in the year preceding the index EDs diagnosis, with mood disorders, generalized anxiety disorder (GAD), post-traumatic stress disorder (PTSD), specific phobia (SP), attention-deficit hyperactivity disorder (ADHD), and autism spectrum disorder (ASD) being the most common. Adjusted analyses showed higher odds for mood disorders (aOR = 1.20 [95% CI = 1.14-1.26]), GAD (aOR = 1.28 [1.21-1.35]), PTSD (aOR = 1.29 [1.18-1.40]), and SP (aOR = 1.45 [1.31-1.60]) in the EDs cohort compared to antidepressant-initiating peers without EDs, although rates of ADHD and ASD were similar in both cohorts. CONCLUSION This large-scale real-time analysis of administrative data illustrates a high burden of co-occurring psychiatric disorders in people with EDs.

Abstract
Background Anorexia nervosa (AN) is a mental and behavioral health condition characterized by an intense fear of weight or fat gain, severe restriction of food intake resulting in low body weight, and distorted self-perception of body shape or weight. While substantial research has focused on general anxiety in AN, less is known about eating-related anxiety and its underlying neural mechanisms. Therefore, we sought to characterize anxiety-to-eat in AN and examine the neurometabolic profile within the dorsal anterior cingulate cortex (dACC), a brain region putatively involved in magnifying the threat response. Methods Women seeking inpatient treatment for AN and women of healthy weight without a lifetime history of an eating disorder (healthy controls; HC) completed a computer-based behavioral task assessing anxiety-to-eat in response to images of higher (HED) and lower (LED) energy density foods. Participants also underwent magnetic resonance spectroscopy of the dACC in a 3 Tesla scanner. Results The AN group reported greater anxiety to eat HED and LED foods relative to the HC group. Both groups reported greater anxiety to eat HED foods relative to LED foods. The neurometabolite myo-inositol (mI) was lower in the dACC in AN relative to HC, and mI levels negatively predicted anxiety to eat HED but not LED foods in the AN group only. mI levels in the dACC were independent of body weight, body mass, and general anxiety. Conclusions These findings provide critical new insight into the clinically challenging feature and underlying neural mechanisms of eating-related anxiety and indicate mI levels in the dACC could serve as a novel biomarker of illness severity that is independent of body weight to identify individuals vulnerable to disordered eating or eating pathology as well as a potential therapeutic target.

Abstract
PURPOSE High levels of physical activity have been documented in eating disorder patients. Our aim was to examine whether adolescent leisure-time physical activity is prospectively associated with eating disorders in adolescence and young adulthood. METHODS Finnish twins born in 1983-1987 reported their physical activity frequency at ages 12, 14, and 17. A subsample of participants underwent structured, retrospective interviews for eating disorders at the mean age of 22.4 years. Associations between female twins' physical activity and future eating disorders (571-683 twins/wave) were investigated with the Cox proportional hazards model. To illustrate the physical activity similarity of the co-twins in a twin pair, we used cross-tabulation of eating disorder-discordant twin pairs (13-24 pairs/wave). RESULTS After adjusting for several covariates, we found no statistically significant longitudinal association between physical activity and eating disorders. This applied when all eating disorders were combined but also when assessed separately as restrictive and non-restrictive eating disorders. Co-twins' physical activity in adolescence tended to be similar irrespective of their future eating disorder, supporting the results of the regression analysis. CONCLUSION We observed no evidence of adolescent physical activity frequency being prospectively associated with eating disorders in female twins. Further longitudinal studies with larger sample sizes and more detailed physical activity data are needed. LEVEL OF EVIDENCE III, evidence obtained from cohort or case-control analytic studies.

Abstract
PURPOSE To develop a systematic review with meta-analysis to summarize the effectiveness of exercise, regular physical activity, and mind-body exercise on harmful exercise habits, psychological factors, and quality of life in people clinically diagnosed with feeding and eating disorders. MATERIAL AND METHODS Randomized clinical trials and pilot randomized clinical trials were considered. RESULTS Twelve studies were included. No studies evaluated athletes. No studies examined regular physical activity as the targeted intervention. Quality of life could not be meta-analyzed. Overall, meta-analyses showed that exercise or mind-body exercise was not more effective than controls in reducing depression symptoms, harmful exercise habits, eating behaviors, or emotional regulation skills. However, important methodological and clinical issues were detected in the included studies. This affected the certainty of evidence of the meta-analyzed outcomes which ranged from low to very low. No studies reported in sufficient detail their interventions to be replicated. CONCLUSIONS Overall, exercise and mind-body exercise may be ineffective in improving meta-analyzed outcomes. However, the certainty of evidence ranged from low to very low and the body of knowledge in this field needs to be increased to reach robust conclusions.

Abstract
BACKGROUND Eating disorders in adolescence are associated with high psychological distress, impaired function and high comorbidity. Despite the severity, eating disorders remain highly underdiagnosed and untreated. Digital technology provides promising opportunities for treatment, however studies focusing on digital treatments for adolescents with eating disorders are lacking. The main aim of this study was to explore the perspectives of adolescents with lived experience of eating disorders on factors they deemed to be relevant in the development of a novel digital treatment. METHODS A qualitative intervention development study using semi-structured individual interviews. Data collection, coding and analysis were conducted using the principles of reflexive thematic analysis. Participants were adolescents aged 16-19 years, with a self-reported diagnosis of anorexia nervosa, bulimia nervosa or binge eating disorder, currently in the final phase or completed psychological treatment for an eating disorder within the last five years. RESULTS A total of 16 adolescents participated in the study, all females. Mean age was 17 ½ years (SD = 1.01). An in-depth understanding of the adolescents' perspectives was developed into three themes: Facilitating self-awareness and readiness to change; Strengthening interpersonal relationships and decreasing social isolation; Ensuring feeling seen and motivating regular use. CONCLUSIONS This study provides a unique insight into the perspectives of adolescents with lived experience of eating disorders. The uptake and engagement can be optimized in a novel digital treatment for eating disorders by taking the adolescents perspectives into consideration.

Abstract
OBJECTIVE To provide a brief overview of artificial intelligence (AI) application within the field of eating disorders (EDs) and propose focused solutions for research. METHOD An overview and summary of AI application pertinent to EDs with focus on AI's ability to address issues relating to data sharing and pooling (and associated privacy concerns), data augmentation, as well as bias within datasets is provided. RESULTS In addition to clinical applications, AI can utilize useful tools to help combat commonly encountered challenges in ED research, including issues relating to low prevalence of specific subpopulations of patients, small overall sample sizes, and bias within datasets. DISCUSSION There is tremendous potential to embed and utilize various facets of artificial intelligence (AI) to help improve our understanding of EDs and further evaluate and investigate questions that ultimately seek to improve outcomes. Beyond the technology, issues relating to regulation of AI, establishing ethical guidelines for its application, and the trust of providers and patients are all needed for ultimate adoption and acceptance into ED practice. PUBLIC SIGNIFICANCE Artificial intelligence (AI) offers a promise of significant potential within the realm of eating disorders (EDs) and encompasses a broad set of techniques that offer utility in various facets of ED research and by extension delivery of clinical care. Beyond the technology, issues relating to regulation, establishing ethical guidelines for application, and the trust of providers and patients are needed for the ultimate adoption and acceptance of AI into ED practice.

Abstract
Eating Disorders (EDs) and related symptoms pose a substantial public health concern due to their widespread prevalence among both genders and associated negative outcomes, underscoring the need for effective preventive interventions. In this context, deepening our understanding of the interplay between ED symptoms and related protective factors appears crucial. Therefore, this study employed a structural network analysis approach considering both ED symptom dimensions (i.e., drive for thinness, bulimic symptoms, and body dissatisfaction) and related protective factors (i.e., body and functionality appreciation, intuitive eating, and self-esteem) to shed light on how these factors are interrelated. A community sample of 1391 individuals (34.4% men; Mage = 26.4 years) completed a socio-demographic schedule and self-report questionnaires. The network showed that the nodes with the highest positive expected influence were body and functionality appreciation, while those with the highest negative expected influence were eating for physical rather than emotional reasons and unconditional permission to eat (i.e., two components of intuitive eating). Crucially, the most relevant bridges between the conceptual communities "ED symptom dimensions" and "Protective factors" were the negative relations between (a) eating for physical rather than emotional reasons and bulimic symptoms, (b) unconditional permission to eat and drive for thinness, and (c) body appreciation and body dissatisfaction. Finally, age, gender, and body mass index did not moderate any edge in the network. The practical implications of these findings are discussed, especially in terms of preventive interventions for ED symptoms.

Abstract
Background Past research indicates that young adult cigarette smokers are at risk of engaging in maladaptive eating behaviors (MEBs); however, whether this relationship extends to nicotine vaping is unclear. The current study assessed bidirectional associations between four types of MEBs and nicotine vaping among young adults. Methods 1,303 young adults (20.5 ± 2.3 years; 63 % female) from a public, urban university were recruited and completed online surveys at six-month intervals from spring 2021 (W1) to spring 2023 (W5). Past 30-day nicotine vaping and four types of MEBs (susceptibility to external cues, emotional eating, routine restraint, and compensatory restraint) were evaluated. Results Longitudinal cross-lagged models examined the bidirectional relationships between past 30-day nicotine vaping and each type of MEB across five waves. Nicotine vaping predicted both susceptibility to external cues (β = 0.10, p <.05; Wave 2 to 3) and emotional eating (β = 0.08, p <.05; Wave 1 to 2). A significant cross-lag regression (Wave 4 to 5) showed nicotine vaping predicted to routine restraint (β = 0.08, p <.05), and routine restraint predicted to nicotine vaping (β = 0.12, p <.05). Conclusions Results indicated that nicotine vaping predicted MEBs; however, the type of MEB differed across waves, which may have been due to the COVID-19 pandemic context. Nicotine vaping predicted to MEBs reflecting vulnerability to the external environment and emotion regulation during a period of heightened restrictions, whereas later when pandemic restrictions had ceased nicotine vaping predicted only to routine restraint. Integrating research and practice on nicotine vaping and MEBs may inform public health efforts to decrease co-occurring health-risks in young adulthood.

Abstract
OBJECTIVE We present the protocol of a feasibility randomised controlled trial (RCT) of intermittent theta burst stimulation (iTBS) for young people with anorexia nervosa (AN). Effective first-line psychological therapies exist for young people with AN, but little is known about how to treat those who do not respond. Non-invasive neuromodulation, such as iTBS, could address unmet treatment needs by targeting neurocircuitry associated with the development and/or maintenance of AN. DESIGN Sixty-six young people (aged 13-30 years) with persistent AN will be randomly allocated to receive 20 sessions of real or sham iTBS over the left dorsolateral prefrontal cortex in addition to their usual treatment. Outcomes will be measured at baseline, post-treatment (1-month post-randomisation) and 4-months post-randomisation (when unblinding will occur). Additional open follow-ups will be conducted at 12- and 24-months post-randomisation. The primary feasibility outcome is the proportion of participants retained in the study at 4-months. Secondary outcomes include AN symptomatology, other psychopathology, quality of life, service utilisation, neurocognitive processes, and neuroimaging measures. DISCUSSION Findings will inform the development of a future large-scale RCT. They will also provide exploratory data on treatment efficacy, and neural and neurocognitive predictors and correlates of treatment response to iTBS in AN.

[PMID: 38664745 PMCID: PMC11046776 DOI: 10.1186/s13104-024-06774-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2023] [Accepted: 04/15/2024] [Indexed: 04/28/2024] Open
Abstract
BACKGROUND Night-Eating Syndrome (NES) is a complex eating disorder that has gained recognition in the context of bariatric surgery. However, its prevalence and associated factors in this specific patient population remain understudied, particularly in the Saudi Arabian context. METHODS This cross-sectional study was conducted at King Abdulaziz University Hospital in Jeddah, Saudi Arabia, from June to November 2022. Adult patients who had undergone bariatric surgery with a postoperative follow-up of 6 months were included. NES was assessed using the Night Eating Questionnaire (NEQ). RESULTS A total of 154 patients were enrolled in the study, with a mean age of 38.8 ± 11.4 years. The mean BMI before surgery was 44.8 ± 8.2 kg/m2, which reduced to 28.9 ± 5.8 kg/m2 post-surgery. Of these, 52 patients (33.8%) met the criteria for NES based on NEQ scores. The prevalence of NES was significantly higher among female patients, with 35 out of 83 females (42.2%) compared to 17 out of 71 males (23.9%) experiencing NES. While NES was not significantly associated with age, nationality, diet adherence, BMI, or surgery type, chronic diseases-particularly diabetes-emerged as significant risk factors for NES in post-bariatric surgery patients. CONCLUSION NES is a prevalent concern among post-bariatric surgery patients, with distinct associations with gender and chronic diseases, particularly diabetes. This study provides valuable insights into NES prevalence and its risk factors in the Saudi Arabian context, highlighting the importance of addressing eating disorders within the framework of bariatric surgery care.

Abstract
Internalizing conditions of psychopathology include depressive and anxiety disorders; they most often onset in adolescence, are relatively common, and contribute to significant population morbidity and mortality. In this research review, we present the evidence that internalizing conditions, including depression and anxiety, as well as psychological distress, suicidal thoughts and self-harm, and fatal suicide, are considerably increasing in adolescent populations across many countries. Evidence indicates that increases are currently greatest in female adolescents. We present an epidemiological framework for evaluating the causes of these increases, and synthesize research on whether several established risk factors (e.g., age of pubertal transition and stressful life events) and novel risk factors (e.g., digital technology and social media) meet conditions necessary to be plausible causes of increases in adolescent internalizing conditions. We conclude that there are a multitude of potential causes of increases in adolescent internalizing conditions, outline evidence gaps including the lack of research on nonbinary and gender nonconforming populations, and recommend necessary prevention and intervention foci from a clinical and public health perspective.

Abstract
Eating disorders (ED) and affective disorders (AD) in adolescent population and several investigations have pointed out that specific family dynamics play a major role in the onset, course, and maintenance of both disorders. The aim of this study was to extend the literature of this topic by exploring differences between parents' personality traits, coping strategies, and expressed emotion comparing groups of adolescents with different mental conditions (anorexia nervosa vs. affective disorder vs. control group) with a case-control study design. A total of 50 mothers and 50 fathers of 50 girls with anorexia nervosa (AN), 40 mothers and 40 fathers of 40 girls with affective disorder (AD), and 50 mothers and 50 fathers of 50 girls with no pathology that conformed the control group (CG) were measured with the Temperament and Character Inventory (TCI), the COPE Inventory, the Family Questionnaire (FQ), and psychopathology variables, anxiety, and depression. Both parents of girls with AN showed a significant difference in personality, coping strategies, and expressed emotion compared to both parents in the CG, while they presented more similarities to parents of girls in the AD group. Identifying personality traits, expressed emotion, coping strategies, and psychopathology of parents and their daughters will allow improvements in the interventions with the adolescents, parents, and families.

Healthcare (Basel) 2024; 12:586. [PMID: 38470697 PMCID: PMC10931238 DOI: 10.3390/healthcare12050586] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2024] [Revised: 02/28/2024] [Accepted: 03/01/2024] [Indexed: 03/14/2024] Open
Abstract
We investigated if interoceptive deficits could be the link between alexithymic traits and eating spectrum manifestations in a non-clinical sample. One-hundred sixty-one young adults (mean age: 23.2 ± 2.4 years) were evaluated with the Toronto Alexithymia Scale-20 (TAS-20), the Interoceptive Accuracy Scale (IAS), the Interoceptive Confusion Questionnaire (ICQ), and the Eating Attitudes Test-26 (EAT-26). Questionnaires were administered with an online procedure (Microsoft Form, Office 365 A1, Pisa, Italy) (Study Protocol #0012005/2023). We compared ICQ, IAS, and TAS-20 scores in subjects who met the threshold for a potential eating spectrum disorder according to EAT-26 scores ≥ 20 (n = 27) vs. subjects who scored <20 (n = 134), with an ANCOVA corrected for 'age' and 'gender'. Subjects with EAT-26 ≥ 20, scored significantly higher at ICQ (54.4 ± 13.2 vs. 50.2 ± 6.8; p = 0.011), TAS-20 'Total Score' (60.8 ± 11.9 vs. 58.1 ± 9.2; p = 0.006), and TAS-20 'Identifying Feelings' (21.5 ± 7.6 vs. 17.3 ± 5.8; p = 0.0001). A binary logistic regression analysis, with EAT-26 scores < 20 vs. ≥20 as the dependent variable, and ICQ, IAS, TAS-20 total scores and dimensions, age, and gender (categorical) as covariates, showed that the only variable predicting eating spectrum symptomatology was 'ICQ Total Score' (OR = 1.075, 95% CI: 1.016-1.139; p = 0.013). Interoceptive confusion was the dimension linking the occurrence of alexithymic traits and eating spectrum manifestations.

Abstract
INTRODUCTION Digital mental health interventions (DMHIs) are getting increasingly important for mental health care. In the case of eating disorders (EDs), DMHIs are still in early stages. Few studies so far investigated the views of mental health professionals for EDs on the integration of DMHIs in routine care. OBJECTIVE To gain insights into the experiences, perspectives, and expectations of mental health professionals for EDs regarding DMHIs and to identify requirements for the future integration of DMHIs into routine care. METHODS Semi-structured qualitative telephone interviews with 24 German mental health professionals treating patients with EDs were conducted. A content analysis following a deductive-inductive approach asked for experiences, advantages and chances, disadvantages and boundaries, desired functions and properties, target groups, and general conditions and requirements for DMHIs for patients with EDs. RESULTS Only few professionals reported experiences with DMHIs besides video-based psychotherapy during the pandemic. From the therapists' point of view, DMHIs have the potential to deliver low-threshold access for patients with EDs. Useful functionalities were seen in digital meal records, skills training, and psychoeducation. However, a stable therapeutic alliance was reported as an important prerequisite for the successful integration into care. Therapists expressed concerns in case of severe anorexia nervosa or suicidality. The participants felt to be informed inadequately on recent developments and on the evidence base of DMHIs. CONCLUSIONS Mental health professionals for EDs show positive attitudes towards DMHIs, however many barriers to the integration in routine care were observed. The highest potential was seen for the use of DMHIs in addition to outpatient care and in aftercare. Specific requirements for DMHIs are related to different areas of the healthcare spectrum and for the different symptom profiles in anorexia nervosa, bulimia nervosa and binge eating disorder. Targeted DMHIs are needed and appropriate especially for concepts of blended care.

Abstract
CONTEXT Anorexia nervosa (AN) can cause severe undernutrition associated with alterations in the IGF axis. Pappalysins (PAPP-A, PAPP-A2) and stanniocalcins (STC-1, STC-2) modulate IGF binding-protein (IGFBP) cleavage and IGF bioavailability, but their implications in AN are unknown. OBJECTIVE We determined serum levels of PAPP-As and STCs in relationship with classical IGF axis parameters in female adolescents with AN and their association with nutritional status and secondary amenorrhea. METHODS Parameters of the IGF axis were determined in fasting serum samples of 68 female adolescents with AN at diagnosis and 62 sex- and age-matched controls. Standardized body mass index (BMI) and bone mineral density (BMD) were calculated. RESULTS Patients with AN had lower concentrations of total and free IGF-I, total IGFBP-3, acid-labile subunit (ALS), insulin, PAPP-A2, STC-1, and STC-2 and higher levels of IGF-II and IGFBP-2. Their free/total IGF-I ratio was decreased and the intact/total IGFBP-3 and -4 ratios increased. BMI was directly related to total IGF-I and intact IGFBP-3 and inversely with IGFBP-2 and intact IGFBP-4. Weight loss was directly correlated with intact IGFBP-4 and negatively with intact IGFBP-3, ALS, STC-2, and PAPP-A2 concentrations. BMD was directly related to intact IGFBP-3 and inversely with intact IGFBP-4 and PAPP-A2 levels. Patients with amenorrhea had lower levels of total IGF-I and IGFBP-3 than those with menses. CONCLUSION The reduction of PAPP-A2 in patients with AN may be involved in a decline in IGFBP cleavage, which could underlie the decrease in IGF-I bioavailability that is influenced by nutritional status and amenorrhea.

Abstract
The prevalence of eating disorders has been increasing over the last 50 years. Binge eating disorder (BED) and bulimia nervosa (BN) are two typical disabling, costly and life-threatening eating disorders that substantially compromise the physical well-being of individuals while undermining their psychological functioning. The distressing and recurrent episodes of binge eating are commonly observed in both BED and BN; however, they diverge as BN often involves the adoption of inappropriate compensatory behaviors aimed at averting weight gain. Normal eating behavior is coordinated by a well-regulated trade-off between intestinal and central ingestive mechanism. Conversely, despite the fact that the etiology of BED and BN remains incompletely resolved, emerging evidence corroborates the notion that dysbiosis of gastrointestinal microbiome and its metabolites, alteration of gut-brain axis, as well as malfunctioning central circuitry regulating motivation, execution and reward all contribute to the pathology of binge eating. In this review, we aim to outline the current state of knowledge pertaining to the potential mechanisms through which each component of the gut-brain axis participates in binge eating behaviors, and provide insight for the development of microbiome-based therapeutic interventions that hold promise in ameliorating patients afflicted with binge eating disorders.

Abstract
OBJECTIVE Hyperemesis gravidarum (HG) is a severe form of excessive vomiting during pregnancy. The connection between psychiatric morbidity and HG has been debated, but only a few studies have focused on eating disorders (EDs). The objective of this study was to evaluate the association between HG and both pre-pregnancy and new post-pregnancy EDs. METHODS A register-based controlled study. HG diagnoses were retrieved from healthcare registers between 2005 and 2017. Women with HG in their first pregnancy resulting in delivery were chosen as cases (n = 4265; the HG group) and women with no HG as controls (n = 302,663; the non-HG group). The associations between EDs and HG were analyzed by binary logistic regression, adjusted with age, body mass index, smoking, socioeconomic status, and pre-pregnancy psychiatric diagnoses. RESULTS In the HG group, 1.6% and in the non-HG group, 0.2% had a pre-pregnancy ED. Women with ED were more likely to have HG in their first pregnancy compared with women with no history of EDs (adjusted odds ratio [AOR] 9.4, 95% CI 6.52-13.66, p < .0001). Moreover, 0.4% of the women in the HG group and 0.1% of the women in the non-HG group had a new ED diagnosis after pregnancy, and thus the women in the HG group were more likely to have an ED diagnosis after pregnancy (AOR I 3.5, 95% CI 1.71-7.15, p < .001, AOR II 2.7, 95% CI 1.30-5.69, p = .008). DISCUSSION We found a bidirectional association between ED and HG, suggesting a shared etiology or risk factors between these disorders. This finding emphasizes the importance of collaboration across various specialties when treating these patients. PUBLIC SIGNIFICANCE Our findings suggest a bidirectional association between HG and EDs before and after pregnancy. This finding provides essential information for healthcare professionals working with pregnant women. As both of these disorders are known to have far-reaching effects on the lives of both the mother and her offspring, our results help clinicians to target special attention and interventions to the patients suffering from these disorders.

Abstract
Despite growing evidence of their prevalence, research on feeding and eating disorders (FEDs) in India has been sporadic. This narrative review aimed to summarize the research on FED in India and set priorities for future research and translation of evidence. An electronic search was conducted in the MEDLINE, PsycINFO, and Google Scholar databases to identify relevant English peer-reviewed articles from April 1967 to July 2023. The extracted data from these studies included author names, publication year, research location, type of intervention (for interventional studies), nature of comparator treatments, and main outcomes or findings. We found a rising trend in the prevalence of EDs in India. Adolescent age group, female sex, higher socioeconomic status, family history of mental illness or disordered eating, and borderline personality pattern were risk factors for EDs. For feeding disorders (FDs), childhood age group, malnutrition, pregnancy, psychosis, intellectual disability (ID), and obsessive-compulsive disorder (OCD) were putative risk factors. Both physical and psychiatric comorbidities were common in FEDs. Culture appears to exert a pathoplastic effect on symptom presentation in FEDs; an illustrative example is the documented nonfat phobic variant of anorexia nervosa (AN) in India. Research on management has focused on using assessment tools, investigations to rule out medical comorbidities, psychosocial and family-based psychotherapies, nutritional rehabilitation, pharmacotherapy, and neuromodulation approaches. Whereas the publication output on FEDs in India has increased over the last decade, it remains an under-researched area, with a striking paucity of original research. Future research priorities in FEDs include conducting country-wide registry-based studies to offer real-world insights, longitudinal research to identify culturally relevant risk factors, and developing brief, culturally sensitive diagnostic instruments for FEDs in the Indian context. This will help generate locally relevant epidemiological data on FEDs and inform treatment and prevention strategies.

Let the Body Talk: Preliminary Data of an Open Trial of Dance Movement Therapy for Eating Disorders. J Clin Med 2023; 13:5. [PMID: 38202012 PMCID: PMC10779718 DOI: 10.3390/jcm13010005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2023] [Revised: 12/14/2023] [Accepted: 12/15/2023] [Indexed: 01/12/2024] Open
Abstract
BACKGROUND There is growing support for considering Dance Movement Therapy (DMT) as an effective approach to improving physical and psychological symptoms in eating disorders (ED), but additional evidence is needed. The current study aims to investigate the effectiveness of a DMT intervention for inpatients with ED during an in-hospital rehabilitation program for ED in reducing emotion dysregulation and alexithymia and improving interoceptive awareness. METHODS Forty-nine consecutive inpatient young women with ED (aged between 18 and 34 years) recruited from a clinical center for the rehabilitation of obesity and ED received four group sessions of DMT intervention. All participants completed the Difficulties in Emotion Regulation Scale (DERS), the Toronto Alexithymia Scale (TAS), and the Multidimensional Assessment of Interoceptive Awareness Scale (MAIA) before (Time 0) and after the intervention (Time 1). Paired-sample t-tests were run to assess differences between Time 0 to Time 1. RESULTS From pre-to-post interventions, there was a significant reduction in the means of all of the subscales of DERS, suggesting an improvement in emotion regulation competencies, with the only exception for difficulties in awareness that increased (p = 0.016). We also found a significant reduction in alexithymia, as proved by significant differences in all of the subscales and the total score of TAS (p < 0.001), and significant improvements in interoceptive awareness as suggested by increased scores of the noticing (p = 0.043), emotional awareness (p < 0.001), body listening (p < 0.001), and trusting (p < 0.001) subscales of MAIA. CONCLUSION Overall, our results point towards the efficacy of dance/movement in reducing symptoms of eating disorders. Our findings also suggest that dancing can be considered a useful intervention to increase emotional regulation, reduce alexithymia, and enhance interoceptive awareness.

Abstract
Anorexia nervosa affects people of all ages, and has the highest mortality rate of all psychiatric disorders, following medical complications inherent in the disease or suicide. Early and appropriate treatment is crucial to prevent the risk of chronic disease, which may affect one in two anorexics. Severe undernutrition linked to a complex psychopathology calls for the necessary theoretical and clinical knowledge on the part of the caregiver, applied to the dynamics of care, ideally conceived in a transdisciplinary way and involving nursing teams.

Abstract
Severe forms of Anorexia Nervosa (AN) are characterized by medical complications, psychiatric comorbidity, and high mortality. This study investigated potential associations between clinical/biological factors and the severity of AN, measured by the Body Mass Index (BMI). Red and white blood cells, hemoglobin, platelets, iron, vitamins D and B12, folate, and total cholesterol were measured in a mixed sample of 78 inpatients and outpatients. Linear regressions and one-way analyses of variance (ANOVAs) were carried out to evaluate the relationship between BMI and clinical/biochemical variables. BMI was significantly lower in hospitalized patients (F = 4.662; p = 0.034) and in those under pharmacological treatment (F = 5.733; p = 0.019) or poly-therapy (F = 5.635; p = 0.021). Higher vitamin B12 (β = -0.556, p < 0.001), total cholesterol (β = -0.320, p = 0.027), and later age at onset (with a trend towards significance) (β = -0.376, p = 0.058) were associated with a lower BMI. Increased total cholesterol and vitamin B12, later age at onset, current pharmacological treatment, and poly-therapy might be distinctive in patients with a lower BMI. In clinical practice, these findings may contribute to the early identification of AN patients at higher risk of developing complicated or chronic forms of the disorder. Further studies on larger samples are needed to identify potential predictive factors of AN severity in the framework of precision medicine.

Abstract
BACKGROUND Eating disorders (EDs) are a group of mental illnesses associated with significant psychological and physiological consequences. Overall, only about one-fifth of individuals with EDs receive treatment and treatment is effective for only about one-third for those who receive care. The development and implementation of effective prevention approaches for those at risk is therefore pivotal. The Body Project is the most effective ED prevention program for at-risk women according to several meta-analyses, but reach is limited since delivery, traditionally, has been in-person. Moreover, peer-led Body Project groups have been reported to produce stronger effects than clinician-led Body Project groups when delivered in-person. This has not yet been examined for virtually delivered Body Project groups. This study therefore seeks to investigate the effect of virtual Body Project groups delivered by peers versus clinicians on ED risk factors, ED symptoms, and prospective ED onset. METHODS Young women with body image concerns aged 16-25 years (N = 441) will be included in the study and randomized to three conditions: (i) virtually delivered Body Project groups led by clinicians; (ii) virtually delivered Body Project groups led by peers; and (iii) psychoeducational control group. Participants will complete assessments at five timepoints over two years (pretest, posttest, 6-months, 1-year, and 2-years). DISCUSSION Further research is needed to examine approaches to increase the potential for broad implementation of prevention of EDs. The virtual modality of the Body Project could markedly expand the reach for young women at risk. If findings confirm that peers can deliver virtual Body Project groups as effectively as clinicians, this will further enhance the implementation potential. TRIAL REGISTRATION The present study has been registered on clinicaltrials.gov (NCT05993728).

Abstract
Eating disorders (EDs) have been understudied and misunderstood in men. Among the relevant factors in the risk, onset, and maintenance of EDs, personality stands out. Therefore, the aim of the study was to analyze the relationships between personality traits and risk variables for the development of EDs in men. A total of 443 male university students (mean = 22.16 years) who completed the Spanish versions of the Eating Disorder Inventory-3 (EDI-3) and the NEO Five-Factor Inventory (NEO-FFI) participated. Correlation analyses were performed, and in order to determine the predictive role of personality traits on risk scales, a hierarchical multiple regression was performed. The results showed that neuroticism was positively associated with drive for thinness, being its main predictor variable. In bulimia, the main relationships were positively associated with neuroticism and negatively with conscientiousness. As for body dissatisfaction, the main predictor variables were neuroticism and, in a negative sense, extraversion and openness to experience. In conclusion, personality traits are related to the risk of developing EDs in male university students, with neuroticism being the main associated trait.

Abstract
OBJECTIVE Little is known about the prevalence of DSM-5 eating disorders (EDs) in adolescents. In Norway, the most recent community-based prevalence study in adolescents was published more than 20 years ago. The aim of this study was to assess the prevalence of DSM-5 EDs in Norwegian adolescents using a two-phase design. METHOD A total of 1558 upper secondary school students (827 girls and 730 boys) (ages 16-19) were screened for at-risk ED pathology using the Eating Disorder Examination-Questionnaire short version (EDE-QS). A sub-sample of 99 adolescents (87 girls and 12 boys) subsequently participated in a clinical interview using the Eating Disorder Assessment for DSM-5 (EDA-5). RESULTS Eating pathology was common, with 19.9% of participants scoring at or above the applied EDE-QS cut-off. The estimated prevalence of any ED was 9.4% in the total sample, and 16.4% in girls. The number of boys who took part in the diagnostic interview was low, thus, diagnostic data from boys were not analyzed separately. Prevalence estimates of AN, BN, BED, and OSFED in girls were 2.7%, 1.1%, 1.9%, and 10.7%. Atypical AN was the most frequently assigned diagnosis in girls. DISCUSSION Sampling biases limit generalizability of results. Additional population-based studies are warranted to assess the prevalence of EDs in Norwegian youth. PUBLIC SIGNIFICANCE STATEMENT In this study, 1558 adolescents, aged 16-19, were screened for ED pathology. A subsample completed a diagnostic interview using DSM-5 criteria. Results showed that one in five adolescents displayed problematic eating behaviors and cognitions. The estimated prevalence rate of any ED was 9.4%. Sampling biases limit generalizability of results. Additional population-based studies are warranted to assess the prevalence of EDs in Norwegian youth.

Abstract
PURPOSE OF REVIEW This review summarizes recent research on eating disorders among gender minorities, transgender and gender diverse people. The focus is on research published in 2022 and the first half of 2023. RECENT FINDINGS Up to 1.2% of young people and 0.3-0.5% of adults identify as transgender, and 2.7-8.4% of young people and 0.3-4.5% of adults report some degree of gender diversity. About 20-50% of transgender and gender diverse people report engaging in disordered eating and >30% screen positive for eating disorder symptoms, and 2-12% have received an eating disorder diagnosis from a health professional. Many transgender and gender diverse people describe eating disorder symptoms as a way of coping with gender dysphoria. They also report high levels of mental and behavioral symptoms, particularly mood and anxiety disorders, suicidal thoughts and behaviors, trauma-related symptoms and disorders, alcohol and substance use, and autism. Gender minorities frequently experience discrimination, victimization, and violence, primarily sexual and physical violence. The minority stress model attributes mental health symptoms to these factors. Promising interventions based on the minority stress model have recently become available, but more research is needed on how to support transgender and gender diverse people with eating disorders. To manage eating disorders in this population, gender-affirming care should be combined with specialist eating disorder treatment. SUMMARY Gender minorities are at high risk for eating disorders. Future studies should assess what is the most appropriate treatment for transgender and gender diverse people with eating disorders.

Abstract
OBJECTIVE The sequential model has been defined as an intensive, two-stage approach that comprises administering two types of treatment consecutively to improve treatment outcomes in cases of non-optimal or absence of treatment response. A psychiatric population that would potentially benefit from the application of the sequential model is the eating disorders (EDs) population. The current scoping review aimed to explore the emerging literature on the application of sequential treatments in EDs. METHOD Using PRISMA and Population intervention comparison outcomes study guidelines, Pubmed and PsycINFO were systematically searched for studies which applied temporally sequential treatments in patients diagnosed with EDs from inception to April 2022 using a combination of keywords. Studies utilising combined or integrated approaches were excluded. RESULTS A total of 12 studies were selected and reviewed. Studies included Bulimia Nervosa, Binge Eating Disorder (BED), or mixed ED samples with a majority of female patients. No studies on AN samples were identified. The majority of studies contained a Cognitive-Behavioural Therapy module of treatment, were conducted on BED patients, were in outpatient settings, and included a group format in one or more treatment conditions. Studies varied in number of comparison groups and study design. Secondary and sequentially applied treatment modules were consistent with treatment recommendations of clinical guidelines. CONCLUSIONS The available data on sequential treatments in EDs is scarce and exhibits methodological limitations that should be addressed in future studies. Definition of sequential treatments in EDs should be further developed to guide robust clinical research and improve empirical support of sequential treatment for complex ED cases and for non-optimal ED treatment response.

Abstract
The present study aimed to identify declared patterns of ideal appearance among students at selected higher education institutions in Poland. In the present study, we set out to identify the body image and the propensity to change it. In order to achieve the goal of the study, a nationwide survey was carried out using a voluntary diagnostic survey. A total of 810 respondents took part in the survey. The study was conducted using a custom-made self-designed survey questionnaire with an indirect interview technique via a web-based platform (CAWI). The study results indicate that women were far more eager to maintain an attractive appearance through dieting than men. Importantly, the respondents, both women and men, did not identify influencers as role models of attractive appearance. Results of the present survey reveal that attitudes towards one's physical appearance are diverse and influenced by the considered factors. The attributes that determined the perception of oneself as an attractive person included height, weight, and body build. Normal body weight is a key feature of an attractive appearance, according to the respondents; nevertheless, students show a higher tolerance for being overweight than for being underweight. Furthermore, preferences in this respect are largely conditioned by individual personal characteristics. According to young people, a person with an attractive appearance is one who eats and exercises regularly, and who does not fall into extremes in terms of their appearance. On the other hand, the fear of growing fat and losing one's attractive appearance was frequently indicated among the concerns over personal appearance. Only one in five respondents expressed complete satisfaction with how they looked, with men and those with a normal BMI significantly more likely to do so. Respondents expressed readiness to undertake a range of activities related to increased exercise regime, changes in their eating habits, or seeking assistance (e.g., of a personal trainer) to achieve the desired body shape. Our findings can be used as a basis for discussion and consideration in developing educational activities on nutrition, as well as on overweight- and obesity-related health issues.

Hirvelä L, Keski-Rahkonen A, Sipilä PN. Associations of broad eating disorder symptoms with later alcohol problems in Finnish adult twins: A nationwide 10-year follow-up. Int J Eat Disord 2023; 56:1854-1865. [PMID: 37353472 DOI: 10.1002/eat.24013] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/07/2023] [Revised: 06/05/2023] [Accepted: 06/06/2023] [Indexed: 06/25/2023]
Abstract
OBJECTIVE Eating disorders are associated with subsequent alcohol problems, but it is not known whether this association also extends to broader eating disorder symptoms not captured by clinical diagnoses. We assessed the longitudinal association of broad eating disorder symptoms with alcohol problems in a nationwide twin sample (FinnTwin16). METHODS Finnish women (N = 1905) and men (N = 1449) self-reported their eating disorder symptoms using the Eating Disorder Inventory-2 Bulimia, Drive for Thinness, and Body Dissatisfaction subscales at the mean age of 24.4 years in 2000-2003. A subsample of participants also completed items on drive for muscularity, height dissatisfaction, and muscle-enhancing supplement use. Alcohol problems were assessed 10 years later at the age of 34.1 in 2010-2012 with the Rutgers Alcohol Problem Index. RESULTS Eating disorder symptoms were associated with later alcohol problems (odds ratio per point increase 1.02-1.18). Bulimia showed stronger associations among men than women (p for interaction .012). Drive for muscularity and height dissatisfaction were also associated with later alcohol problems, but supplement use was not. When accounting for baseline alcohol problems, only Bulimia (among women and men) and Drive for Thinness (among men) were significantly associated with later alcohol problems. Bulimia was also significantly associated with later alcohol problems in within-twin-pair analyses among dizygotic twins, but not among monozygotic twins. DISCUSSION In a longitudinal setting, eating disorder symptoms were associated with later alcohol problems. Bulimic symptoms were a stronger risk factor for men than women. These associations may be attributable to baseline alcohol problems, childhood environment and genetic liability. PUBLIC SIGNIFICANCE This study found that both young adult women and men with broad eating disorder symptoms are at a higher risk of alcohol-related problems than those without such symptoms. Men with bulimic symptoms were at a particularly high risk. These findings emphasize the need for better prevention and treatment of disordered eating, body image concerns and alcohol problems for both young adult women and men.

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

Abstract
Eating pathology is increasingly common among Indian adolescents. However, brief validated measures of disordered eating in Indian contexts are scarce. This study adapted and validated a culturally appropriate English language version of the Child Eating Disorder Examination Questionnaire (ChEDE-Q) among 385 adolescents (mean age = 13.42 years; 47.3% girls) in urban India. Confirmatory factor analysis indicated that a two-factor eight-item solution had an acceptable fit to the data across gender: an 'Eating Concerns and Restraint' subscale and a 'Weight and Shape Concerns' subscale. Further, the questionnaire can be utilised as both a unidimensional and multidimensional tool. This allows for the computation of a total score on the primary factor of 'Child Eating Pathology', as well as the two subscales. Internal consistency of the 'Weight and Shape Concerns' subscale (α = 0.825) and 'Eating Concerns and Restraint' subscale (α = 0.649) was satisfactory. Concurrent validity was established through medium significant correlations with measures of body image and broader mental health. The results support the use of the ChEDE-Q for assessing disordered eating among urban Indian adolescents, thus providing the research community and practitioners with a measure to investigate the nature and scale of disordered eating among adolescents in India.

The Impact of the COVID-19 Pandemic on Binge Eating Disorder: A Systematic Review. Nutrients 2023; 15:3777.

Abstract
The aim of this systematic review was to synthesise the impact of the COVID-19 pandemic on binge eating disorder (BED) the new onset and course. Inclusion criteria: original articles and BED diagnosis; and the main outcomes: relationships between the COVID-19 pandemic and the new onset/clinical changes in BED, and specific results for BED. Exclusion criteria: mixed/inaccurate diagnoses and articles not written in English. We searched four databases and one registry until 5 May 2023. The quality appraisal was conducted using the Effective Public Health Practice Project (EPHPP) tool. Twelve studies with 4326 participants were included. All studies were observational with nine cross-sectional and three longitudinal. Four of the included studies investigated new-onset BED, while eight examined the BED clinical course of patients with a previous diagnosis. With the exception of one study, the available literature indicates both an increase in BED diagnoses and a clinical worsening during COVID-19. Major limitations include study quality (weak-to-moderate) and high heterogeneity in terms of pandemic phase, population, geographical areas, and psychometric tools. Our findings indicate that BED patients are particularly vulnerable to events characterised by social distancing and over-worry, and should be, therefore, carefully monitored. Further studies are needed to corroborate our findings, implement preventive strategies, and promote personalised treatments. PROSPERO registration number: CRD42023434106.

Abstract
Youth with chronic health conditions face an elevated risk of eating disorders and disordered eating behaviors. Contributors to this phenomenon may include the unique threats faced by this vulnerable population to their body image, their relationships with food and eating, and their mental health and self-esteem. However, youth with chronic health conditions may also experience more severe medical complications and mortality from eating disorder behaviors because of the additional risks conveyed by their underlying conditions. In this review, clinical strategies are provided to support youth with chronic health conditions through early recognition of eating disorder behaviors and prompt referral to treatment, which is important for a better prognosis. Suggestions are also given to mitigate their risk of developing eating disorders by proactively addressing risk factors and offering thoughtful anticipatory guidance that promotes a positive relationship with food and eating.

Abstract
OBJECTIVE Estimate the prevalence, and associated risk factors, of high school students who are considered at risk for an eating disorder based on screening measures. METHODS An electronic search of nine databases was completed from their inception until 1st September 2022. A random-effects meta-analysis was conducted, and confounder (moderator) analyses and meta-regressions examined whether the overall prevalence estimate for of screen-based disordered eating (SBDE) was moderated by student age, BMI, or gender, as well as culture and type of SBDE assessment. RESULTS The mean estimate of the prevalence of SBDE among high school students (K = 42 (66 datapoints), N = 56282] in the sample of 25 countries was 13% ([95% CI] = 10.0-16.8%, I2 = 99.0%, Cochran's Q p = 0.001). This effect was not moderated by features of the samples such as gender, BMI, or age. Among cultures, non-Western countries had a higher prevalence of SBDE prevalence than Western countries, but the difference was not significant. There was considerable variability in the prevalence estimates as a function of the assessment measure, but no meaningful pattern emerged. CONCLUSION The estimated figure of 1 in 8 high school students with SBDE-unmoderated by gender and BMI-stands out as a problem in need of attention from public health officials, psychologists, psychiatrists, pediatricians, parents, and educators. There is a great need for innovative, integrated policy and program development all along the spectrum of health promotion and universal, selective, and indicated prevention. Further research is also needed to validate and refine this estimate by (a) conducting basic research on the accuracy of eating disorder screening measurements in samples ages 14 through 17; (b) examining representative samples in more countries in general and Latin American countries in particular; (c) clarifying the relationships between SBDE and age throughout the different phases of late childhood, adolescence, and emerging adulthood; and (d) investigating whether there are meaningful forms of disordered eating and whether these are associated with variables such as gender, ethnicity, and BMI.

Abstract
Anorexia nervosa (AN) is a chronic, life-threatening disease with mental and physical components that include excessive weight loss, persistent food restriction, and altered body image. It is sometimes accompanied by hyperactivity, day-night reversal, and amenorrhea. No medications have been approved specific to the treatment of AN, partially due to its unclear etiopathogenesis. Because adiponectin is an appetite-regulating cytokine released by adipose tissue, we hypothesized that it could be useful as a specific biomarker that reflects the disease state of AN, so we developed a modified AN mouse model to test this hypothesis. Twenty-eight 3-week-old female C57BL/6J mice were randomly assigned to the following groups: 1) no intervention; 2) running wheel access; 3) food restriction (FR); and 4) activity-based anorexia (ABA) that included running wheel access plus FR. After a 10-day cage adaptation period, the mice of the FR and ABA groups were given 40% of their baseline food intake until 30% weight reduction (acute FR), then the body weight was maintained for 2.5 weeks (chronic FR). Running wheel activity and the incidence of the estrous cycle were assessed. Spontaneous food restriction and the plasma adiponectin level were evaluated at the end of the acute and chronic FR phases. An increase in running wheel activity was found in the light phase, and amenorrhea was found solely in the ABA group, which indicates that this is a good model of AN. This group showed a slight decrease in spontaneous food intake accompanied with an attenuated level of normally induced plasma adiponectin at the end of the chronic FR phase. These results indicate that the plasma adiponectin level may be a useful candidate biomarker for the status or stage of AN.

Abstract
BACKGROUND Eating disorders (EDs) are associated with a risk of premature death, as well as suicidal and self-injurious behavior. A low or high body mass index (BMI) and weight control behavior can also have an impact on self-injurious and suicidal behavior. While some studies show that interpersonal sensitivity is a risk factor for EDs, affective disorders, and self-injurious behavior, in-depth studies of these issues have not been done. AIM The present study investigates how self-injurious and suicidal behavior relate to weight control behavior, BMI, and interpersonal sensitivity in adolescent girls from a clinical population with diagnosed EDs compared with adolescent girls from the general population. METHODS The main group was comprised of 31 girls with a diagnosis of ED (as the main diagnosis or co-occurring with affective disorders, M=151.13 years), being treated in in the Eating Disorder Clinic of the Scientific and Practical Center for Mental Health of Children and Adolescents named after G.E. Sukhareva. The comparison group consisted of 27 adolescent girls recruited from Proton Educational Center (M=15.511.09 years). The measures included a qualitative survey that yielded data on weight control behavior, and self-injurious behavior, a Blitz questionnaire probing the suicide risk (used only in the main group), and the Interpersonal Sensitivity Measure. Height and weight data were also recorded for BMI calculation. RESULTS The qualitative analysis of weight control behavior yielded the following results: purging behavior, restrictive behavior, and corrective behavior. Participants in the main group used purging and restrictive behavior more often, whereas participants in the comparison group used strategies associated with a healthy lifestyle. The main group and participants who practiced purging and restrictive weight control in the overall sample had the smallest BMI. Self-injurious behavior was approximately evenly distributed both amongst the main and comparison groups. Self-cutting was the most prevalent type of self-injury. In the main group, self-injury was associated with a smaller BMI, while in the comparison group it was associated with an increase in the fear of rejection and overall interpersonal sensitivity. Based on the assessment of the suicide risk, six participants in the main group were deemed high-risk; they also displayed increased fear of rejection, dependence on the assessments of others, and overall interpersonal sensitivity. All girls in the suicide risk subgroup had non-suicidal self-injuries. CONCLUSION The results of our study broaden our understanding of the risk factors of suicidal and self-injurious behavior in adolescent girls with EDs and reveal the characteristics of the type of weight control behavior used by this group in comparison with adolescent girls in the general population. Girls with EDs who were considered at the risk of committing suicide demonstrated high interpersonal sensitivity, which provides a rationale for further studying the general interpersonal mechanisms that underlie the pathogenesis of EDs, as well as that of self-injurious and suicidal behavior.

Abstract
Anorexia nervosa (AN) is associated with hyperactivity, amenorrhea, and brain atrophy. The underlying pathophysiology is mostly unknown, and new targets for therapeutic interventions are needed. This study aimed to systematically establish a murine AN model with the parameter extent of starvation, animal age, and length of starvation for functional studies. The activity-based anorexia (ABA) model combines food restriction with running wheel access. Early adolescent and adolescent mice received 40% of their baseline food intake until a 20% or 25% weight reduction was reached (acute starvation). To mimic chronic starvation, body weight loss was maintained for another two weeks. Running activity was examined using wheel sensors, while amenorrhea was investigated by analysis of vaginal smears. Brain sections were used to analyze cerebral cortex volumes. Acute starvation did not lead to either AN-related symptoms, whereas chronic starvation led to hyperactivity and amenorrhea except in the adolescent cohort with 20% weight reduction. Only ABA mice with 25% weight reduction revealed a cortex volume reduction. The optimal parameters to mirror AN-related symptoms included a 25% weight reduction, early adolescent or adolescent mice, and chronic starvation. The ABA model enables functional analysis of the impact of chronic AN on the underlying hormonal, behavioral, and brain pathophysiology.
