Bioelectrical Impedance Vector Analysis, Nutritional Ultrasound ®, and Handgrip Strength as Innovative Methods for Monitoring Critical Anorexia Nervosa Physical Recovery: A Pilot Study. Nutrients 2024; 16:1539. [PMID: 38794777 PMCID: PMC11123858 DOI: 10.3390/nu16101539] [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: 04/23/2024] [Revised: 05/14/2024] [Accepted: 05/16/2024] [Indexed: 05/26/2024] Open
Abstract
Eating disorders (EDs) manifest as persistent disruptions in eating habits or related behaviors, significantly impacting physical health and psychosocial well-being. Nutritional assessment in ED patients is crucial for monitoring treatment efficacy. While dual-energy X-ray absorptiometry (DEXA) remains standard, interest in alternative methods such as bioelectrical impedance vector analysis (BIVA) and Nutritional Ultrasound® (NU) has risen due to their affordability and portability. Additionally, hand dynamometry offers a user-friendly approach to assessing grip strength (HGS), indicative of nutritional status. A prospective study was carried out to evaluate the utility of BIVA, NU®, and HGS in 43 female AN patients. Measurements were taken at baseline and hospital discharge. A total of 41 patients completed the study. After the intervention, numerous BIVA-related parameters such as fat (3.5 ± 2 kg vs. 5.3 ± 2.7 kg, p < 0.001) and free fat mass (33.9 ± 3.8 kg vs. 37.5 ± 4.1 kg, p < 0.001) were partially restored. Similarly, Nutritional Ultrasound® showed promising results in assessing body composition changes such as total abdominal fat tissue (0.5 ± 0.3 cm vs. 0.9 ± 0.3 cm, p < 0.05). In the same way, rectus femoris cross-sectional area values correlated with clinical outcomes such as free fat mass (0.883, p < 0.05) and appendicular muscle mass (0.965, p < 0.001). HGS reached the normality percentile after the intervention (21.6 ± 9.1 kg vs. 25.9 ± 12.3 kg, p < 0.05), demonstrating a significant association between grip strength and body composition parameters such as free fat mass (0.658, p < 0.001) and appendicular muscle mass (0.482, p < 0.001). Incorporating BIVA-, NU®-, and HGS-enhanced nutritional assessment into the treatment of AN patients offers cost-effective, portable, and non-invasive alternatives to DEXA. These techniques offer valuable insights into changes in body composition and nutritional status, which, in turn, facilitate treatment monitoring and contribute to improved patient outcomes.

Abstract
OBJECTIVES Binge spectrum disorders are prevalent worldwide. Psychiatric and medical comorbidities are common, and societal costs are significant. Evidence-based treatment remains underutilized. Cognitive behavioral therapy is the recommended first-line treatment, but pharmacotherapy may be easier to access. INTERVENTIONS Meta-analytic evidence directly comparing cognitive behavioral therapy with pharmacotherapy is lacking. We aimed to compare the effects of cognitive behavioral therapy interventions with any pharmacological treatment for binge spectrum disorders. We searched PubMed, Embase, CENTRAL, ClinicalTrials.gov and reference lists for randomized controlled trials comparing cognitive behavioral therapy with any pharmacotherapy for bulimia nervosa/binge eating disorder and performed pairwise meta-analytic evaluations. PRIMARY OUTCOMES Primary outcomes are remission and frequency of binges. Secondary outcomes are frequency of purges, response, eating disorder psychopathology, weight/body mass index, depression, anxiety, quality of life and dropouts. RESULTS Eleven randomized controlled trials comparing cognitive behavioral therapy with fluoxetine/imipramine/desipramine/methylphenidate/sibutramine were identified (N = 531). Cognitive behavioral therapy was superior to antidepressants in terms of remission, frequency of binges and eating disorder psychopathology. There were no statistically significant differences for any of the individual cognitive behavioral therapy vs drug comparisons in terms of response/depression/anxiety/weight/quality of life/dropouts. Cognitive behavioral therapy was not superior to sibutramine/methylphenidate for the primary outcomes. CONCLUSIONS Data are scarce, comparisons underpowered and, considering the inherent methodological limitations of psychotherapy trials, questions arise regarding the presumed superiority of cognitive behavioral therapy. Further research is needed.

Abstract
Purpose The objective of this study was to conduct a secondary data analysis of clinical information documented in the electronic medical record to assess the clinical outcomes of patients who received three different treatment approaches on clinical outcomes for treatment of patients with anorexia nervosa (AN). Patients and methods Historical electronic medical record (EMR) data on patients aged 6 to 80 years diagnosed with AN seen in a healthcare system between 2007 and 2017 were stratified, according to services received, into three groups: Group A (n = 48) received hospital-based services; Group B (n = 290) saw one or two provider types; Group C (n = 26) received outpatient coordinated multidisciplinary care from three provider types. Clinical outcomes [body mass index for adults (BMI), body mass index percentile (BMI%ile) for pediatric patients] defined AN severity and weight restoration. EMR data were analyzed using a generalized mixed-effects model and a Markov Transition model to examine the odds of weight restoration and the change in odds of weight restoration across the number of provider visits, respectively. Results Patients receiving coordinated multidisciplinary care had significantly higher odds of weight restoration compared with patients receiving hospital-based services only (OR = 3.76, 95% CI [1.04, 13.54], p = 0.042). In addition, patients receiving care from 1 to 2 providers (OR = 1.006, 95% CI [1.003, 1.010], p = 0.001) or receiving coordinated multidisciplinary care (OR = 1.005, 95% CI [1.001, 1.011], p = 0.021) had significantly higher odds of weight restoration per provider visit day compared with patients receiving hospital-based services only. Conclusion This retrospective chart review supports the coordinated, multidisciplinary care model for the weight restoration in patients with AN in an outpatient setting.

Abstract
BACKGROUND Severe and enduring anorexia nervosa (SE-AN), is a serious and persistent illness, despite 'state of the art' treatment. Criteria have been theoretically proposed, but not tested, and may not adequately capture illness complexity, which potentially inhibits treatment refinements. The clinical reality of death as an outcome for some people who experience SE-AN (1 in 20) and broadening access to voluntary assisted dying, further complicates the field, which is undeveloped regarding more fundamental concepts such as nosology, treatment, recovery definitions and alternative conceptualisations of SE-AN. The present paper is in response to this and aims to build upon qualitative literature to enhance phenomenological understandings of fatal SE-AN. METHOD A published book, being the legacy of a 32-year-old professional artist offers a rich account of a life lived with AN, for 18 years with continuous treatment. A polysemous narrative via the interrelationship between the languages of the artist's words and visual art is translated via interpretative phenomenological analysis (IPA), offering rich insight into the SE-AN experience. FINDINGS The process of analysis induced three superordinate themes (1) Disappearing Self (2) Dialectical Dilemma (3) Death and Dying: Finding Meaning. Two cross cutting themes traversed these themes: (a) Colour and (b) Shifting Hope, where the former produced a visual representation via the 'SE-AN Kaleidoscope'. Collectively the themes produce a concept of SE-AN, grounded in the data and depicted visually through the artist's paintings. CONCLUSIONS The picture of SE-AN revealed in the analysis extends upon conceptualisations of SE-AN, highlighting key processes which are thus far under explored. These factors are implicated in illness persistence eliciting opportunities for further research testing including diagnostic considerations and treatment directions. In SE-AN, distorted body image extends to a global distortion in the perception of self. Additional criteria for the severe and enduring stages of illness related to (1) self and identity processes (2) measures of 'global impoverishment' across life domains are proposed for consideration in the future testing of putative defining features of SE-AN.

Abstract
BACKGROUND The current study examined whether risk factors for anorexia nervosa (AN) were related to different levels of severity based on (a) the DSM-5/body mass index (BMI) and (b) drive for thinness (DT) severity ratings. METHODS The sample comprised 153 pairs of individuals with a lifetime diagnosis AN per DSM-IV criteria and their non-ED sisters (N = 306, mean age = 26.53; mean current BMI = 20.42 kg/m2). The Oxford risk factor interview was used to establish AN-related risk factors. Individuals were categorised into the DSM-5 severity groups based on their lowest BMI, while the DT subscale from the eating disorder inventory-2 was used to classify individuals with AN into low and high DT groups. RESULTS Multinominal regression models showed similar risk factors (e.g., perfectionism, having a history of being teased about weight and shape) contributed to the development of AN using the DSM-5 and DT severity ratings. Follow-up analyses across the severity groups for both indices revealed that only childhood perfectionism was found to be more common in the extreme severe DSM-5 BMI severity group compared to the severe DSM-5 group. CONCLUSION Overall, this study found little evidence for AN risk factors being related to the DSM-5 and DT severity ratings. However, given the novelty of this study, replication of the current results is warranted.

Abstract
Using a male eating disorder (ED) sample, this study assessed the clinical utility of the Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5) severity indices for males with anorexia nervosa (AN) and bulimia nervosa (BN) and compared it to an alternative transdiagnostic severity categorisation based on drive for thinness (DT). The participants included 143 males with an ED (60 [42.0%] AN and 83 [58.0%] BN) diagnosis, who were classified using these two severity classifications. The different severity categories were then compared based on ED symptoms, general psychopathology, and personality traits. Our results revealed that the DSM-5 "mild" and DT "low" severity categories were most prevalent in the AN and BN male patients. Clinically significant findings were strongest for the DT categorisation for both AN and BN. The current findings provide initial support for an alternative transdiagnostic DT severity classification for males that may be more clinically meaningful than the DSM-5 severity indices.

Abstract
BACKGROUND Anorexia Nervosa (AN) poses significant therapeutic challenges, especially in cases meeting the criteria for Severe and Enduring Anorexia Nervosa (SE-AN). This subset of AN is associated with severe medical complications, frequent use of services, and the highest mortality rate among psychiatric disorders. CASE PRESENTATION In the present case series, 14 patients were selected from those currently or previously taken care of at the Eating Disorders Outpatients Unit of the Maggiore Hospital in Bologna between January 2012 and May 2023. This case series focuses on the effects of the disease, the treatment compliance, and the description of those variables that could help understand the great complexity of the disorder. CONCLUSION This case series highlights the relevant issue of resistance to treatment, as well as medical and psychological complications that mark the life course of SE-AN patients. The chronicity of these disorders is determined by the overlapping of the disorder's ego-syntonic nature, the health system's difficulty in recognizing the problem in its early stages, and the presence of occupational and social impairment.

Abstract
Although many researchers addressed the topics, no consistent data are currently available regarding the relationship between perfectionism and personality traits in anorexia nervosa (AN). The present study aimed to assess differences between high- and low-perfectionism groups of patients with AN and to identify which variables show the strongest association with perfectionism. A group of inpatients with AN (n = 193) was recruited and completed a battery of self-report questionnaires regarding eating-related and general psychopathology, perfectionism, and personality. On the basis of perfectionism scores, patients were divided into high- and low-perfectionism groups. High-perfectionist patients displayed higher eating-related and general psychopathology; higher depressive, cyclothymic, irritable and anxious temperament, and lower self-directedness, cooperativeness and self-esteem. Perfectionism was associated with the drive for thinness, cooperativeness, self-esteem and anxious temperament. On the basis of the two personality traits most strongly correlated with perfectionism (i.e., cooperativeness and anxious temperament), patients could be correctly assigned to the high- or low-perfectionism group by an algorithm. The study suggests that perfectionism in AN is related to eating psychopathology, especially of restrictive type, and personality features such as cooperativeness and anxious temperament. These findings confirm the important role of perfectionism in AN, not only concerning eating behaviour but personality as well.

Drive for thinness (DT) and duration of illness have been proposed as two alternative severity measures, however their empirical evidence is also limited. To date, no research has assessed the validity of current eating disorder (ED) severity criteria regarding cognitive flexibility factors. Cognitive flexibility is often impaired in EDs, becoming a possible severity symptom. The current study assessed for the first time (1) whether the severity indexes for EDs proposed in the DSM-5 were associated with deficits in cognitive flexibility and, (2) whether drive for thinness and illness duration, acted as an alternative, more meaningful severity indices for deficiencies in cognitive flexibility. METHODS Participants were 161 patients diagnosed with an ED, who were categorized according to DSM-5 severity categories, DT and duration of illness. Discriminative capacity of each classification was assessed for cognitive flexibility measured by Wisconsin card sorting test (WCST). RESULTS The findings for the DSM-5 classification comprised: (a) In the anorexia nervosa (AN) group, patients with moderate severity showed better scores in WCST than patients with mild and severe/extreme severity. Also, patients with moderate severity showed lower percentage of cognitive flexibility deficits than the other two severity categories; (b) For the binge spectrum disorders (BSD) group, the patients with mild severity showed a higher percentage of cognitive flexibility deficits than did the moderate and severe/extreme categories. When assessing the alternative severity index of DT, no differences were found in cognitive flexibility in any of the groups. Regarding illness duration, in the AN group the task performance of the patients with longer illness duration was worse than the performance of the short duration group and, in the BSD group, patients with longer duration also showed more deficits in cognitive flexibility than the patients with shorter duration of illness. CONCLUSIONS Our findings point out the limitations of the DSM-5 severity criteria to categorize cognitive flexibility in EDs and support illness duration as an alternative severity approach for EDs.

Abstract
BACKGROUND Severe and enduring anorexia nervosa (SE-AN) is amongst the most impairing of all mental illnesses. Collective uncertainties about SE-AN nosology impacts treatment refinement. Qualitative research, particularly lived experience literature, can contribute to a process of revision and enrichment of understanding the SE-AN experience and further develop treatment interventions. Poor outcomes to date, as evidenced in clinical trials and mortality for people with SE-AN (1 in 20) demonstrate the need for research that informs conceptualisations and novel treatment directions. This interpretative, meta-ethnographic meta-synthesis aimed to bridge this gap. METHODS A systematic search for qualitative studies that explored the AN experiences of people with a duration of greater than 3 years was undertaken. These studies included those that encompassed phenomenology, treatment experiences and recovery. RESULTS 36 papers, comprising 382 voices of SE-AN experiences informed the meta-ethnographic findings. Four higher order constructs were generated through a synthesis of themes and participant extracts cited in the extracted papers: (1) Vulnerable sense of self (2) Intra-psychic processes (3) Global impoverishment (4) Inter-psychic temporal processes. Running across these meta-themes were three cross cutting themes (i) Treatment: help versus harm, (ii) Shifts in control (iii) Hope versus hopelessness. These meta-themes were integrated into conceptualisations of SE-AN that was experienced as a recursive process of existential self-in-relation to other and the anorexia nervosa trap. CONCLUSIONS The alternative conceptualisation of SE-AN proposed in this paper poses a challenge to current conceptualisations of AN and calls for treatments to engage with the complex intra and inter-psychic processes of the SE-AN, more fully. In doing so, clinicians and researchers are asked to continue to be bold in testing novel ideas that may challenge our own rigidity and attachment to dominant paradigms to best serve the individual person with SE-AN. The 'global impoverishment of self', found in this synthesis of AN experiences, should inform proposed diagnostic criteria for SE-AN.

Abstract
BACKGROUND Binge-type eating disorders (EDs; i.e., bulimia nervosa, binge eating disorder) are common among young adults with high body weight, yet few interventions target both conditions. This study tested an online guided self-help intervention that provided cognitive behavioral therapy (CBT) tools for EDs and behavioral weight loss (BWL) content to young adults with binge-type EDs and high body weight. METHOD 60 adults aged 18-39 with clinical/subclinical binge-type EDs and high body weight were randomized to a combined condition or a CBT-only condition. Participants received self-help content for 8 weeks and self-reported ED attitudes, frequency of binge eating and compensatory behaviors, and weight at baseline, 4-weeks, and 8-weeks. Linear mixed models and negative binomial models compared changes between conditions in ED attitudes, ED behaviors, and weight at each timepoint. Chi-square test and independent samples t-test compared program completion and session engagement between conditions. RESULTS No significant differences in weight change or ED symptom change emerged between the conditions. Both conditions achieved significant reductions in ED attitudes, binge episodes, and compensatory behaviors from baseline to 8-weeks (ps < .05). Neither condition demonstrated significant weight loss from baseline to 8-weeks. Program completion (47 %) and session engagement (57 %) were equally high across conditions. DISCUSSION Both conditions achieved ED symptom change; however, neither condition was associated with weight change. Research is needed to identify the types of strategies and doses of BWL that promote clinically significant weight and ED symptom change in young adults.

Assessing severity in anorexia nervosa: Do the DSM-5 and an alternative severity rating based on overvaluation of weight and shape severity differ in psychological and biological correlates? EUROPEAN EATING DISORDERS REVIEW 2023. [PMID: 36694105 DOI: 10.1002/erv.2969] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2022] [Revised: 11/19/2022] [Accepted: 01/10/2023] [Indexed: 01/26/2023]
Abstract
OBJECTIVE This study evaluated the severity ratings for anorexia nervosa (AN) in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and an alternative severity rating based on overvaluation of weight/shape, on a range of psychological and biological variables. METHOD A sample of 312 treatment-seeking patients with AN (mean age = 25.3, SD = 7.6; mean BMI = 16.8 kg/m2 , SD = 2.4) were categorised using both DSM-5 severity levels (mild/moderate/severe/extreme) and weight/shape (low/high) overvaluation. The severity categories were compared on a range of psychological (e.g., eating psychopathology) and biological (e.g., sodium) variables. RESULTS Results showed that the overvaluation of weight/shape appeared better at indexing the level of severity in psychological variables among patients with AN compared to the DSM-5 severity rating with moderate to large effect sizes. Moreover, the DSM-5 mild and moderate severity groups experienced significantly higher eating and general psychopathology than the severe and extreme groups. Finally, neither the DSM-5 nor the weight/shape severity groups differed on any of the biological variables. CONCLUSIONS This study provided no support for the DSM-5 severity rating for AN, while initial support was found for the weight/shape overvaluation approach in indexing psychological but not biological correlates.

Presentation of Patients with Eating Disorders to a Pediatric Quaternary-Level Care Emergency Department During the COVID-19 Pandemic. Psychiatr Q 2022; 93:935-946.

Abstract
Despite an overall decrease in utilization of emergency departments during COVID-19 (Hartnett et al. in MMWR Morb Mortal Wkly Rep. 69(23):699-704, 2020), US pediatric emergency departments experienced an increase in mental health visits for children and adolescents (Leeb et al. in MMWR Morb Mortal Wkly Rep. 69(45):1675-80, 2020). Simultaneously, individuals with eating disorders reported increasing symptomology (Termorshuizen et al. in Int J Eat Disord. 53(11):1780-90, 2020). This study compares Emergency Department utilization at a pediatric quaternary-level care center by patients with eating disorders during the pandemic (March-Dec 2020) vs March-Dec 2019. We hypothesize that there was an increase in presentation of patients with eating disorders. An Informatics for Integrating Biology and the Bedside query of the electronic medical record system identified patients with eating disorder diagnoses per ICD9/ICD10 codes aged 6-23 who presented to the Emergency Department between March 1st and December 31st of 2020 and 2019. Subsequent retrospective chart review was carried out. Patients were excluded from analysis if the presenting problem was not directly related to the eating disorder. During March-Dec 2019, 0.581% percent of all patients presented to the Emergency Department due to an eating disorder. During the same time frame in 2020, however, that percentage increased to 1.265%. Statistical significance was corrected using a Benjamini-Hochberg analysis. Despite a 66.5% decline in overall visits to the Emergency Department, the percentage of patients presenting with eating disorders doubled during the pandemic. During the pandemic, the total time spent awaiting placement significantly increased, and the number of patients identifying as transgender and/or nonbinary increased. Our data support the hypothesis that eating disorder presentation increased during the pandemic.

Abstract
OBJECTIVE Effective treatments exist for binge-eating disorder (BED), although roughly 50% of patients fail to attain binge-eating abstinence. Evidence on how to refine treatments is lacking. Conceptualizing BED as arising from a network of symptom-to-symptom interactions allows for the identification of the most strongly connected symptoms, which could inform intervention targets. This study assessed how BED symptom centrality changed with behaviorally based weight-loss treatments (BBWLTs). METHODS Participants were 191 adult patients (71% female, 79% White) with BED with comorbid obesity participating in a randomized controlled trial testing 6-month BBWLTs for BED. Independent assessments of BED symptoms were performed at pretreatment, posttreatment, and 12 months after treatment. Strength centrality indicated how strongly and frequently symptoms were associated with each other in the network. Significant changes in centrality between timepoints were determined using permutation tests. RESULTS At pretreatment, overvaluation of shape/weight and preoccupation with shape/weight and food/eating had the highest strength centrality. At posttreatment and 12-month follow-up, dissatisfaction with shape/weight had the highest centrality, which significantly increased from pretreatment. CONCLUSIONS The relations among symptoms of BED are not static and change over time with treatment. BBWLTs do not appear to reduce connectivity of overvaluation of shape/weight (the most central BED symptom prior to treatment), but instead increase connectivity of dissatisfaction with shape/weight with other symptoms following treatment. The observed network structure of symptoms following BBWLTs resembles network analyses of people without eating disorders. Findings highlight the importance of understanding how treatments impact symptom relationships, not just symptom intensities. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Abstract
Background This Obesity Medicine Association (OMA) Clinical Practice Statement (CPS) is intended to provide clinicians an overview of "Behavior, Motivational Interviewing, Eating Disorders, and Obesity Management Technologies." Methods The scientific information for this CPS is based upon published scientific citations, clinical perspectives of OMA authors, and peer review by the Obesity Medicine Association leadership. Results This CPS outlines important components of behavior, motivational interviewing, eating disorders, and obesity management technologies as they relate to pre-obesity and obesity. Topics include eating behavior disorder evaluation, the motivations behind eating and physical activity behaviors (including underlying neurophysiology, eating disorders, environmental factors, and personal prioritization), motivational interviewing techniques, and technologies that may assist with pre-obesity/obesity management. Conclusions This Obesity Medicine Association (OMA) Clinical Practice Statement (CPS) on "Behavior, Motivational Interviewing, Eating Disorders, and Obesity Management Technologies" is one of a series of OMA CPSs designed to assist clinicians in the care of patients with the disease of pre-obesity/obesity. Implementation of appropriate clinical practices in these areas may improve the health of patients, especially those with adverse fat mass and adiposopathic metabolic consequences.

Abstract
OBJECTIVE CBT-T is a brief (10 sessions) version of cognitive behavioral therapy for non-underweight eating disorders. This report describes the protocol for a single center, single group, feasibility trial of online CBT-T in the workplace as an alternative to the health-service setting. By offering mental health services for eating disorders in the workplace, greater accessibility and increased help-seeking behaviors could be achieved. METHOD Treatment will be delivered online over 10 weeks and offered to employees based on self-referral rather than meeting diagnostic criteria, making treatment available to employees with sub-threshold eating disorder symptoms. RESULTS Assessments will be conducted at baseline, mid-treatment (week 4), posttreatment (week 10) and at follow-up (1 month and 3 months posttreatment). For the primary outcome, measures will include recruitment, attrition and attendance data using pre-set benchmarks to determine high, medium or low feasibility and acceptability. Qualitative participant experiences data will be analyzed using thematic analysis. Impact on work engagement and effect sizes will be determined from secondary outcome measures; the latter enabling sample size calculations for future study. DISCUSSION These pilot data will provide insights to recruitment, acceptability, effectiveness and viability of a future fully powered clinical trial of online CBT-T in the workplace. PUBLIC SIGNIFICANCE STATEMENT This study will present feasibility data from an eating disorders intervention (online CBT-T) using the workplace as an alternative to the healthcare setting to recruit and treat workers. Recruitment will be based on self-reported eating and weight concerns rather than diagnosis potentially enabling treatment to employees who have not previously sought help. The data will also provide insights to recruitment, acceptability, effectiveness, and future viability of CBT-T in the workplace.

Abstract
BACKGROUND Eating-disorder severity indicators should theoretically index symptom intensity, impairment, and level of needed treatment. Two severity indicators for binge-eating disorder (BED) have been proposed (categories of binge-eating frequency and shape/weight overvaluation) but have mixed empirical support including modest clinical utility. This project uses structural equation model (SEM) trees - a form of exploratory data mining - to empirically determine the precise levels of binge-eating frequency and/or shape/weight overvaluation that most significantly differentiate BED severities. METHODS Participants were 788 adults with BED enrolled in BED treatment studies. Participants completed interviews and self-report measures assessing eating-disorder and comorbid symptoms. SEM Tree analyses were performed by specifying an outcome model of BED severity and then recursively partitioning the outcome model into subgroups. Subgroups were split based on empirically determined values of binge-eating frequency and/or shape/weight overvaluation. SEM Forests also quantified which variable contributed more improvement in model fit. RESULTS SEM Tree analyses yielded five subgroups, presented in ascending order of severity: overvaluation <1.25, overvaluation = 1.25-2.74, overvaluation = 2.75-4.24, overvaluation ⩾4.25 with weekly binge-eating frequency <4.875, and overvaluation ⩾4.25 with weekly binge-eating frequency ⩾4.875. SEM Forest analyses revealed that splits that occurred on shape/weight overvaluation resulted in much more improvement in model fit than splits that occurred on binge-eating frequency. CONCLUSIONS Shape/weight overvaluation differentiated BED severity more strongly than binge-eating frequency. Findings indicate a nuanced potential BED severity indicator scheme, based on a combination of cognitive and behavioral eating-disorder symptoms. These results inform BED classification and may allow for the provision of more specific and need-matched treatment formulations.

Abstract
The validity of body mass index (BMI) specifiers for anorexia nervosa (AN) has been questioned, but their applicability to inpatients with extremely low BMIs and their prognostic validity are currently unknown. Therefore, we designed this study: (a) to test current BMI specifiers in severe inpatients; (b) to explore a "very extreme" specifier (VE-AN; BMI ≤ 13.5); and (c) to verify inpatients' hospitalization outcome according to BMI severity. We enrolled 168 inpatients with AN completing the following: Eating disorder Examination-Questionnaire, Eating Disorder Inventory-2, State-Trait Anxiety Inventory, Beck Depression Inventory, Body Shape Questionnaire, and EQ-5D-VAS. According to the current BMI classification, those with a BMI < 15 versus those with non-extreme AN (NE-AN, BMI ≥ 15) differed on all measures but the quality of life with those with NE-AN reporting more impaired scores on all measures. Adopting an exploratory classification comparing VE-AN, extreme AN (E-AN, BMI = 13.6-14.99), and NE-AN, no differences emerged between VE-AN and E-AN, while those with NE-AN reported significantly more impaired scores on all variables while the quality of life again did not differ across groups. Hospitalization outcome improved for all groups, independently of BMI. Groups differed concerning the length of stay that mirrored BMI severity and impacted also hospitalization outcomes. Taken together, our data support the lack of validity of current BMI specifiers in AN, even in the acute setting. Moreover, the exploratory subgroup of patients with BMI ≤ 13.5 did not delineate a clinically different group.

Nutrients 2021; 13:nu13082834. [PMID: 34444994 PMCID: PMC8400545 DOI: 10.3390/nu13082834] [Citation(s) in RCA: 21] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2021] [Revised: 08/10/2021] [Accepted: 08/12/2021] [Indexed: 11/16/2022] Open
Abstract
Research about stigmatization in eating disorders (EDs) has highlighted stereotypes, prejudices, and discrimination against people with EDs, as well as their harmful effects on them, including self-stigma and a difficult recovery process. Whereas a recent review focused on the consequences of ED stigma, our work aimed to provide a broader synthesis of ED stigma, including its consequences, but also its content and distribution. More precisely, we focused on three EDs-namely, anorexia nervosa, bulimia nervosa, and binge eating disorder. Based on a systematic search of four major databases in psychology, the present scoping review includes 46 studies published between 2004 and 2021. We did not conduct any quality assessment of the studies included, because our aim was to provide a wide-ranging overview of these topics instead of an appraisal of evidence answering a precise research question. The review confirmed the existence of a common ED stigma: all individuals affected by EDs reviewed here were perceived as responsible for their situation, and elicited negative emotions and social distance. However, our review also depicted a specific stigma content associated with each ED. In addition, the demographic characteristics of the stigmatizing individuals had a notable influence on the extent of ED stigma: men, young adults, and low-income individuals appeared to be the most stigmatizing toward individuals with EDs. It is important to note that ED stigma had a negative effect on individuals' eating disorders, psychological wellbeing, and treatment-seeking behavior. There is an urgent need for further research on the adverse effects of ED stigma and its prevention.

Abstract
Features of personality disorders (PDs) have been found to explain meaningful variance in the onset, maintenance, and symptomatic presentation of eating disorders (EDs), and a co-occurent personality pathology is commonly associated with poorer response to ED treatment. The "pathoplasty model" of the relationship between personality and EDs implies that, once both conditions are established, they are likely to interact in ways that modify therapy outcome; however, to date, no studies have explored overall personality functioning, and especially PD clusters, as a mediator of treatment outcome. The present study aimed at conjointly exploring the associations between personality functioning and PDs, respectively, with pre-treatment ED symptomatic impairment and therapy outcome; and the mediating role of personality variables. At treatment onset, a sample of 107 women with ED problems were evaluated using both the Structured Clinical Interview for DSM-5 (SCID-5-CV) and the Shedler-Westen Assessment Procedure-200 (SWAP-200)-a clinician-rated procedure to dimensionally assess personality. Participants were also asked to complete self-report questionnaires on overall ED symptomatology, symptoms of binge eating and purging behaviors, and therapy outcome. The findings showed that, over and above the categorical ED diagnosis, the SWAP-200 healthy personality functioning score mediated the relationship between baseline ED symptom severity and therapy outcome, as well as the association between baseline bulimic symptoms and treatment outcome; furthermore, SWAP-200 Cluster B PD scores mediated the link between baseline binge eating and purging symptoms and therapy outcome, whereas scores in Clusters A and C showed no significant effects. The findings suggest that personality-based outcome research may improve treatment effectiveness in this difficult-to-treat population.

Age dependency of body mass index distribution in childhood and adolescent inpatients with anorexia nervosa with a focus on DSM-5 and ICD-11 weight criteria and severity specifiers. Eur Child Adolesc Psychiatry 2021; 30:1081-1094.

Abstract
Both DSM-5 and ICD-11 have provided weight cut-offs and severity specifiers for the diagnosis of anorexia nervosa (AN) in childhood, adolescence and adulthood. The aims of the current study focusing on inpatients aged < 19 years were to assess (1) the relationship between age and body mass index (BMI; kg/m2), BMI-centiles, BMI-standard deviation scores (BMI-SDS) and body height-SDS at referral, (2) the percentages of patients fulfilling the DSM-5 and ICD-11 weight criteria and severity categories for AN, and (3) the validity of the AN severity specifiers via analysis of both weight related data at discharge and inpatient treatment duration. The German Registry for Anorexia Nervosa encompassed complete data sets for 469 female patients (mean age = 15.2 years; range 8.9-18.9 years) with a diagnosis of AN (n = 404) or atypical AN (n = 65), who were ascertained at 16 German child and adolescent psychiatric hospitals. BMI at referral increased up to age 15 to subsequently plateau. Approximately one tenth of all patients with AN had a BMI above the fifth centile. The ICD-11 specifier based on a BMI-centile of 0.3 for childhood and adolescent AN entailed two equally sized groups of patients. Discharge data revealed limited validity of the specifiers. Height-SDS was not correlated with age thus stunting had no impact on our data. We corroborate the evidence to use the tenth instead of the fifth BMI-centile as the weight criterion in children and adolescents. Weight criteria should not entail major diagnostic shifts during the transition from adolescence to adulthood. The severity specifiers based on BMI or BMI-centiles do not seem to have substantial clinical validity.

Abstract
Feeding and eating disorders in ICD-11 Abstract. Innovations in ICD-11 include the adoption of a lifespan approach and culture-related guidance for each disorder. We describe the changes made to the chapter Feeding and Eating Disorders and compared them to the ICD-10. In addition to illustrating the revision of the guidelines for each disorder, we also comment on the inclusion of a new set of diagnoses, avoidant/restrictive food intake disorder (ARFID) and binge-eating disorder (BED).

Abstract
OBJECTIVE To assess an alternative trans-diagnostic indicator for severity based on drive for thinness (DT) for anorexia nervosa (AN), bulimia nervosa (BN), binge-eating disorder (BED), and other specified feeding or eating disorder (OSFED), and to compare this new approach to the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) severity categories for EDs. METHOD A total of 2,811 ED [428 AN-restrictive (AN-R), 313 AN-binge purging (AN-BP), 1,340 BN, 329 BED, 154 OSFED/atypical AN (AT), and 223 OSFED/purging disorder (PD)] patients were classified using: (a) The DSM-5 severity categories and (b) a DT categorisation. These severity classifications were then compared based on ED symptoms, general psychopathology, personality, and impulsive behaviours. RESULTS For the DSM-5 categories, most ED patients fell into the 'mild' to 'moderate' categories. Using the DT categories, AN patients were mainly represented in the 'low' DT category, and BN, OSFED/AT, and PD in the 'high' DT category. The clinically significant findings were stronger for the DT than the DSM-5 severity approach (medium-to-large effect sizes). AN-BP and AN-R provided the most pronounced effects. CONCLUSION Our findings question the clinical value of the DSM-5 severity categorisation, and provide initial support for an alternative DT severity approach for AN. HIGHLIGHTS : This study assessed an alternative trans-diagnostic drive for thinness (DT) severity. Category for all eating disorder (ED) sub-types, and then compared this to the Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5) severity indices for EDs. ED symptoms, general psychopathology, personality, and impulsive behaviours were assessed using both classifications in a total of 2,811 female patients diagnosed with EDs. Clinically significant findings were stronger for the DT than the DSM-5 severity category (medium-to-large effect sizes); there was differentiation of the anorexia nervosa (AN) patients into mainly 'low' DT, and bulimia nervosa (BN) spectrum patients into mainly 'high' DT, vs. most patients were clustered in the 'mild-to-moderate' DSM-5 categories. Our findings provide initial support for an alternative trans-diagnostic DT severity category that may be more clinically meaningful than the DSM-5 severity indices for EDs.

Abstract
BACKGROUND We explored the utility of "staging" anorexia nervosa (AN) by duration of illness and psychological wellbeing. We also investigated 12-month symptom trajectories and service usage in a large cohort of patients with AN assessed for outpatient treatment. METHOD We conducted secondary analyses on data from a multisite clinical trial of adults with AN (n = 187) recruited from 22 NHS England specialist eating disorder (ED) services into a digital treatment augmentation study. Clinical outcomes and service use were measured at postintervention (six weeks), 6 and 12 months. We grouped patients into two categories: "early stage" (illness duration <3 years; n = 60) and "severe and enduring" stage (SE-AN; n = 41) indicated by distress (Depression Anxiety and Stress Scales, DASS ≥60) and illness duration (≥7 years). RESULTS At 12 months, patients reported large improvements in body mass index, small to moderate improvements in ED symptoms, mood, and work/social adjustment, and 23.6% met criteria for recovery. However, patients classified as SE-AN reported higher rates of accessing intensive services, higher ED symptomatology, and poorer work/social adjustment at baseline, and lower rates of improvement in work/social adjustment at 12 months compared to "early stage" respondents. DISCUSSION Although present findings suggest overall symptomatic improvements, exploratory results highlight marked differences in course and service use between people at different stages of AN, suggesting a need to consider staging for clinical decision-making. Further research differentiating between clinical subtypes of AN and adoption of a more personalized approach may ensure that services and care pathways better fit patient needs.

Investigating resting brain perfusion abnormalities and disease target-engagement by intranasal oxytocin in women with bulimia nervosa and binge-eating disorder and healthy controls. Transl Psychiatry 2020; 10:180.

Abstract
Advances in the treatment of bulimia nervosa and binge-eating disorder (BN/BED) have been marred by our limited understanding of the underpinning neurobiology. Here we measured regional cerebral blood flow (rCBF) to map resting perfusion abnormalities in women with BN/BED compared with healthy controls and investigate whether intranasal oxytocin (OT), proposed as a potential treatment, can restore perfusion in disorder-related brain circuits. Twenty-four women with BN/BED and 23 healthy women participated in a randomized, double-blind, crossover, placebo-controlled study. We used arterial spin labelling MRI to measure rCBF and the effects of an acute dose of intranasal OT (40 IU) or placebo over 18-26 min post dosing, as we have previously shown robust OT-induced changes in resting rCBF in men in a similar time-window (15-36 min post dosing). We tested for effects of treatment, diagnosis and their interaction on extracted rCBF values in anatomical regions-of-interest previously implicated in BN/BED by other neuroimaging modalities, and conducted exploratory whole-brain analyses to investigate previously unidentified brain regions. We demonstrated that women with BN/BED presented increased resting rCBF in the medial prefrontal and orbitofrontal cortices, anterior cingulate gyrus, posterior insula and middle/inferior temporal gyri bilaterally. Hyperperfusion in these areas specifically correlated with eating symptoms severity in patients. Our data did not support a normalizing effect of intranasal OT on perfusion abnormalities in these patients, at least for the specific dose (40 IU) and post-dosing interval (18-26 min) examined. Our findings enhance our understanding of resting brain abnormalities in BN/BED and identify resting rCBF as a non-invasive potential biomarker for disease-related changes and treatment monitoring. They also highlight the need for a comprehensive investigation of intranasal OT pharmacodynamics in women before we can fully ascertain its therapeutic value in disorders affecting predominantly this gender, such as BN/BED.

Abstract
An update of the chapter on Mental, Behavioral and Neurodevelopmental Disorders in the International Classification of Diseases and Related Health Problems (ICD) is of great interest around the world. The recent approval of the 11th Revision of the ICD (ICD-11) by the World Health Organization (WHO) raises broad questions about the status of nosology of mental disorders as a whole as well as more focused questions regarding changes to the diagnostic guidelines for specific conditions and the implications of these changes for practice and research. This Forum brings together a broad range of experts to reflect on key changes and controversies in the ICD-11 classification of mental disorders. Taken together, there is consensus that the WHO's focus on global applicability and clinical utility in developing the diagnostic guidelines for this chapter will maximize the likelihood that it will be adopted by mental health professionals and administrators. This focus is also expected to enhance the application of the guidelines in non-specialist settings and their usefulness for scaling up evidence-based interventions. The new mental disorders classification in ICD-11 and its accompanying diagnostic guidelines therefore represent an important, albeit iterative, advance for the field.

Abstract
OBJECTIVE To test the validity and clinical utility of the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) severity specifiers for binge-eating disorder (BED) in predicting treatment outcomes. METHOD Participants (N = 521) were patients in randomized controlled trials (RCTs) at 1 medical center testing treatments for BED; data were aggregated from RCTs testing cognitive-behavioral therapy (CBT), behavioral weight loss (BWL), and/or multimodal (i.e., CBT or BWL plus pharmacotherapy) treatment. Participants were categorized according to DSM-5 severity specifiers for BED: "mild" (n = 273; 52.5%), "moderate" (n = 182; 34.9%), and "severe/extreme" (n = 58; 11.1%). Participants had their weight and height measured and were assessed using established interviews and self-report measures at baseline, throughout treatment, and post treatment. RESULTS Mixed models revealed that severity category did not significantly predict treatment response. However, there were main effects of BED severity category: "Severe/extreme" BED had greater binge-eating frequency and had greater global eating-disorder psychopathology than did "mild" BED across all time points. "Severe/extreme" BED was less likely to have remission from binge eating than was "mild" BED. Weight loss and depression scores did not significantly differ by severity category. CONCLUSION In a large series of treatment-seeking individuals with BED aggregated across RCTs at 1 medical center testing psychological and pharmacological treatments for BED, DSM-5 severity specifiers for BED had limited validity and utility predicting response to treatments. Future research is needed to identify more robust severity indicators with clinical utility to inform future DSM revisions and clinical practice.

Abstract
The Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) for 6 feeding and eating disorders were published in 2013 and were notable for officially recognizing binge-eating disorder and for articulating criteria for avoidant/restrictive food intake disorder. The criteria and the rationale for them are briefly described, and current and future challenges are discussed.

An investigation of indirect effects of personality features on anorexia nervosa severity through interoceptive dysfunction in individuals with lifetime anorexia nervosa diagnoses. Int J Eat Disord 2019; 52:200-205. [PMID: 30636025 DOI: 10.1002/eat.23008] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/27/2018] [Revised: 12/08/2018] [Accepted: 12/09/2018] [Indexed: 12/11/2022]
Abstract
OBJECTIVE This study examined a hypothesized pathway by which interoceptive dysfunction accounted for associations between personality features (harm avoidance, self-directedness, and perfectionism) and anorexia nervosa (AN) severity (indicated by drive for thinness, eating disorder-related preoccupations and rituals, and body mass index). METHOD The study sample (n = 270, mean age = 28.47, 95.2% female, 98% White/Caucasian) consisted of probands and biological relatives who met DSM-IV criteria for lifetime diagnoses of AN (omitting criterion D, amenorrhea) drawn from the Price Foundation Anorexia Nervosa Affected Relative Pairs Study (AN-ARP). Participants completed measures assessing personality, interoceptive dysfunction, and eating pathology. RESULTS Associations between personality features of low self-directedness and high perfectionism and indicators of AN severity (drive for thinness and eating disorder-related preoccupations and rituals) were significant, as were the hypothesized indirect pathways through interoceptive dysfunction. Neither harm avoidance nor body mass index was significantly related to other study variables, and the proposed indirect pathways involving these variables were not significant. DISCUSSION Findings suggest that certain personality features may relate to AN severity, in part, through their associations with interoceptive dysfunction. Future research should examine prospective associations and the value of interventions targeting interoceptive dysfunction for interrupting the link between personality and AN severity.

Abstract
OBJECTIVE The aim of this study was to evaluate treatment outcomes across the BMI (body mass index)-based DSM-5 severity specifiers in a sample of adult females with anorexia nervosa (AN) treated with enhanced cognitive behavioural therapy (CBT-E). METHOD One hundred and twenty-eight participants with AN (64 outpatients and 64 inpatients) were sub-categorised using DSM-5 severity specifiers and compared by baseline clinical characteristics and treatment outcomes at the end of treatment and at 6- and 12-month follow-ups. RESULTS No significant differences were found across the four severity groups for 'weight recovery' (i.e., BMI ≥ 18.5 kg/m2) or 'good outcome' (i.e., BMI ≥ 18.5 kg/m2 and minimal accompanying eating disorder psychopathology). DISCUSSION Our data suggest that the DSM-5 severity specifiers for anorexia nervosa may have limited clinical utility in predicting treatment outcomes of CBT-E.

Abstract
OBJECTIVE Despite changes to the diagnostic criteria for eating disorders (EDs) in the DSM-5, the current diagnostic system for EDs has limited ability to inform treatment planning and predict outcomes. Our objective was to test the clinical utility of a novel dimensional approach to understanding the structure of ED psychopathology. METHOD Participants (N = 243; 82.2% women) were community-recruited adults with a DSM-5 ED assessed at baseline, 6-month, and 1-year follow-up. Hierarchical factor analysis was used to identify a joint hierarchical-dimensional structure of eating, mood, and anxiety symptoms. Exploratory structural equation modeling was used to test the ability of the dimensional model to predict outcomes. RESULTS At the top of the hierarchy, we identified a broad Internalizing factor that reflected diffuse symptoms of eating, mood, and anxiety disorders. Internalizing branched into three subfactors: distress, fear-avoidance (fears of certain stimuli and behaviors to neutralize fears, including ED behaviors designed to reduce fear of weight gain), and body dissatisfaction, which was nested within distress. The lowest level of the hierarchy was characterized by 15 factors. The hierarchical model predicted 60.1% of the variance in outcomes at 6-month follow-up, whereas all DSM eating, mood, and anxiety disorders combined predicted 35.8% of the variance in outcomes. DISCUSSION A dimensional approach to understanding and diagnosing EDs improved the ability to prospectively predict clinical course above-and-beyond the traditional categorical (DSM-based) approach. Our findings have implications for endeavors to improve the prediction of ED prognosis and course, and to develop more effective trans-diagnostic treatments.

Testing the relative associations of different components of dietary restraint on psychological functioning in anorexia nervosa and bulimia nervosa. Appetite 2018; 128:1-6. [PMID: 29807122 DOI: 10.1016/j.appet.2018.05.138] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2018] [Revised: 04/11/2018] [Accepted: 05/24/2018] [Indexed: 10/16/2022]
Abstract
Although empirical evidence identifies dietary restraint as a transdiagnostic eating disorder maintaining mechanism, the distinctiveness and significance of the different behavioural and cognitive components of dietary restraint are poorly understood. The present study examined the relative associations of the purportedly distinct dietary restraint components (intention to restrict, delayed eating, food avoidance, and diet rules) with measures of psychological distress (depression, anxiety, and stress), disability, and core eating disorder symptoms (overvaluation and binge eating) in patients with anorexia nervosa (AN) and bulimia nervosa (BN). Data were analysed from a treatment-seeking sample of individuals with AN (n = 124) and BN (n = 54). Intention to restrict, food avoidance, and diet rules were strongly related to each other (all r's > 0.78), but only weakly-moderately related to delayed eating behaviours (all r's < 0.47). In subsequent moderated ridge regression analyses, delayed eating was the only restraint component to independently predict variance in measures of psychological distress. Patient diagnosis did not moderate these associations. Overall, findings indicate that delayed eating behaviours may be a distinct component from other indices of dietary restraint (e.g., intention to restrict, food avoidance, diet rules). This study highlights the potential importance of ensuring that delayed eating behaviours are screened, assessed, and targeted early in treatment for patients with AN and BN.
