St-Pierre MJ, Therriault PY, Faghihi U, Monthuy-Blanc J. Eating disorders: When food "Eats" time. Appetite 2023; 185:106509. [PMID: 36871602 DOI: 10.1016/j.appet.2023.106509] [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: 10/18/2022] [Revised: 01/20/2023] [Accepted: 02/22/2023] [Indexed: 03/07/2023]
Abstract
The presence of a physical or mental health issue, such as an eating disorder (ED), impacts daily activities, also known as occupations. For example, an overinvestment in body shape and weight undoubtedly can lead to an underinvestment in other, more meaningful occupations. To address ED-related perceptual disturbances, a detailed log of daily time use can pinpoint food-related occupational imbalances. This study aims to characterize the daily occupations associated with EDs. The first specific objective (SO.1) is to categorize and quantify the temporal organization of a typical day's occupations as self-reported by individuals with an ED. The second specific objective (SO.2) is to compare daily occupational time use among people with different ED types. This retrospective study based on time-use research principles was conducted by analyzing data from an anonymized secondary dataset (Loricorps's Databank). Data were collected between 2016 and 2020, from 106 participants, with descriptive analysis completed to determine the average daily time use for each occupation. A series of one-way analyses of variance (ANOVAs) were performed to compare perceived time use in each occupation for participants with different types of EDs. The outcomes show a marked underinvestment in leisure categories compared to the general population. In addition, personal care and productivity can represent the blind dysfunctional occupations (SO.1). Moreover, compared to those with binge eating disorder (BED), individuals with anorexia nervosa (AN) are significantly more invested in occupations that focus explicitly on perceptual disturbances, such as personal care (SO.2). The highlight of this study is the distinction between marked versus blind dysfunctional occupation, which offers specific avenues for clinical intervention.

The cerebellum gains weight: A systematic review of alterations in cerebellar volume and cerebro-cerebellar functional alterations in individuals with eating disorders. Neurosci Biobehav Rev 2022; 141:104863.

Abstract
BACKGROUND Brain imaging studies on eating disorders (EDs) often reported volumetric and functional changes involving the cerebellum. Nevertheless, few studies performed in-depth examinations and suggested a cerebellar role in the EDs' pathophysiology. METHODS A systematic literature search on volumetric changes and functional alterations involving the cerebellum in individuals with EDs was conducted using PubMed, PsychInfo and Web of Science. This review was conducted according to the Preferred Reporting Items for Systematic Reviews (PRISMA) statement and Rayyan web application for screening studies. RESULTS Twenty-four papers reporting cerebellar alterations in individuals with EDs were included in the study: 9 assessing brain volumetric changes, 9 investigating task-based functional brain activation and 6 investigating brain functional connectivity at rest. Most studies focused on anorectic-type EDs (n.22), while fewer involved bulimic-type EDs (n.9) and eating disorders not otherwise specified (n.2), revealing subtypes-specific patterns of altered cerebellar volume and functionality. CONCLUSIONS This review proposes critical arguments to consider the cerebellum as a key structure in the pathophysiology of EDs that requires further forthcoming exploration.

Abstract
Background: In recent years a new term in the field of eating behaviors has emerged, namely “orthorexia”. This behavior is associated with significant dietary restrictions and omission of food groups. The aim of the present study is to estimate the possible correlations between orthorexia and eating disorders in young adults and adolescents. Methods: A systematic review of related articles in PubMed, Google Scholar, and PsycInfo was conducted up to 30 June 2021. Results: A total of 37 studies (16,402 subjects) were considered eligible for this systematic review. Significant correlations were observed in most of the studies between orthorexia and eating disorders. However, the majority of studies adopted a cross-sectional design. Conclusions: An association between and eating disorders emerged. Prospective studies seem necessary to investigate associations and succession of orthorexia and eating disorders over time.

Abstract
Introduction: Clinical and genetic study of psychiatric conditions has underscored the co-occurrence of complex phenotypes and the need to refine them. Bipolar Disorder (BD) and Binge Eating (BE) behavior are common psychiatric conditions that have high heritability and high co-occurrence, such that at least one quarter of BD patients have BE (BD + BE). Genetic studies of BD alone and of BE alone suggest complex polygenic risk models, with many genetic risk loci yet to be identified. Areas covered: We review studies of the epidemiology of BD+BE, its clinical features (cognitive traits, psychiatric comorbidity, and role of obesity), genomic studies (of BD, eating disorders (ED) defined by BE, and BD + BE), and therapeutic implications of BD + BE. Expert opinion: Subphenotyping of complex psychiatric disorders reduces heterogeneity and increases statistical power and effect size; thus, it enhances our capacity to find missing genetic (and other) risk factors. BD + BE has a severe clinical picture and genetic studies suggests a distinct genetic architecture. Differential therapeutic interventions may be needed for patients with BD + BE compared with BD patients without BE. Recognizing the BD + BE subphenotype is an example of moving towards more precise clinical and genetic entities.

Abstract
Introduction Orthorexia nervosa, a term used to describe an obsession with healthy eating, has been shown to have major health implications for those affected. The aim of this study was to validate a Spanish version of the Düsseldorfer Ortorexie Skala (DOS), a questionnaire for the detection of orthorexic behavior. Methods A cross-sectional study comprising a total sample of 492 Spanish participants recruited from the University of Castilla-La Mancha, Spain, and randomly divided into two groups. The following tools were applied: the DOS and the Eating Disorder Inventory (EDI-2). The factorial structures were analyzed using exploratory and confirmatory factorial analysis. Results The internal consistency of the DOS-ES was α = .841. The exploratory factor analysis has revealed the existence of a single factor with factor loadings ranging from .508 to .802. A confirmatory factor analysis was applied to the second half of the random sample in order to confirm the factor solution. Conclusion The Spanish adaptation of the DOS-ES is proven to be a reliable and valid questionnaire for evaluating the obsessive tendency towards healthy eating among university students.

Abstract
BACKGROUND Functional magnetic resonance imaging (fMRI) has provided insight on how neural abnormalities are related to the symptomatology of the eating disorders (EDs): anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED). More specifically, an increasingly growing number of brain imaging studies has shed light on how functionally connected brain networks contribute not only to disturbed eating behavior, but also to transdiagnostic alterations in body/interoceptive perception, reward processing and executive functioning. METHODS This narrative review aims to summarize recent advances in fMRI studies of patients with EDs by highlighting studies investigating network alterations that are shared across EDs. RESULTS AND CONCLUSION Findings on reward processing in both AN and BN patients point to the presence of altered sensitivity to salient food stimuli in striatal regions and to the possibility of hypothalamic inputs being overridden by top-down emotional-cognitive control regions. Additionally, innovative new lines of research suggest that increased activations in fronto-striatal circuits are strongly associated with the maintenance of restrictive eating habits in AN patients. Although significantly fewer studies have been carried out in patients with BN and BED, aberrant neural responses to both food cues and anticipated food receipt appear to occur in these populations. These altered responses, coupled with diminished recruitment of prefrontal cognitive control circuitry, are believed to contribute to the binge eating of palatable foods. Results from functional network connectivity studies are diverse, but findings tend to converge on indicating disrupted resting-state connectivity in executive networks, the default-mode network and the salience network across EDs.

Abstract
Taste preferences and health concerns play important roles in determining eating attitudes, thus influencing food choices. Disordered eating attitudes are common among women, and can lead to the development and maintenance of eating disorders (ED). Attitudes toward health and taste of food among ED patients and its comparison with non-clinical women are not well known, and this knowledge could improve eating interventions. In this study, we compared taste preferences and health concerns in 27 women with diagnosis of bulimia nervosa (BN) and 216 women of a non-clinical sample. All participants completed the Health and Taste Attitude Scale (HTAS). Using analysis of covariance we compared the HTAS scores of the BN patients with those of the college students. Risk behaviors for ED (assessed by the Eating Attitudes Test) were identified in 54 (25%) of the non-clinical sample, all of whom were therefore excluded in comparison of BN patients. Non-clinical sample, compared to patients, scored higher on the HTAS Taste domain (p < 0.001) and its pleasure subscale (p < 0.001), whereas patients scored higher on the HTAS Health domain (p < 0.05) and its light product interest subscale (p < 0.05). Based on our data, eating attitudes of women of non-clinical sample are related to taste and pleasure, whereas women with BN are concerned with adopting a diet regarded as healthy, thus increasing their interest in "light" products. Therefore, the taste and health concerns must be considered in nutrition interventions for women in general, and prevention and treatment of ED as determinants of food choice.

Abstract
OBJECTIVE Review the clinical skills needed to recognize, diagnose, and manage binge-eating disorder (BED) in a primary care setting. DATA SOURCES A PubMed search of English-language publications (January 1, 2008-December 11, 2014) was conducted using the term binge-eating disorder. Relevant articles known to the authors were also included. STUDY SELECTION/DATA EXTRACTION Publications focusing on preclinical topics (eg, characterization of receptors and neurotransmitter systems) without discussing clinical relevance were excluded. A total of 101 publications were included in this review. RESULTS Although BED is the most prevalent eating disorder, it is underdiagnosed and undertreated. BED can be associated with medical (eg, type 2 diabetes and metabolic syndrome) and psychiatric (eg, depression and anxiety) comorbidities that, if left untreated, can impair quality of life and functionality. Primary care physicians may find diagnosing and treating BED challenging because of insufficient knowledge of its new diagnostic criteria and available treatment options. Furthermore, individuals with BED may be reluctant to seek treatment because of shame, embarrassment, and a lack of awareness of the disorder. Several short assessment tools are available to screen for BED in primary care settings. Pharmacotherapy and psychotherapy should focus on reducing binge-eating behavior, thereby reducing medical and psychiatric complications. CONCLUSIONS Overcoming primary care physician- and patient-related barriers is critical to accurately diagnose and appropriately treat BED. Primary care physicians should take an active role in the initial recognition and assessment of suspected BED based on case-finding indicators (eg, eating habits and being overweight), the initial treatment selection, and the long-term follow-up of patients who meet DSM-5 BED diagnostic criteria.

Abstract
The objective of this review was to examine the evidentiary basis for binge eating disorder (BED) with reference to the Diagnostic and Statistical Manual of Mental Disorders - Fifth Edition (DSM-5) diagnostic criteria for BED. A PubMed search restricted to titles and abstracts of English-language reviews, meta-analyses, clinical trials, randomized controlled trials, journal articles, and letters using human participants was conducted on August 7, 2015, using keywords that included "binge eating disorder," DSM-5, DSM-IV, guilt, shame, embarrassment, quantity, psychological, behavior, and "shape and weight concerns." Of the 257 retrieved publications, 60 publications were considered relevant to discussions related to DSM-5 diagnostic criteria and were included in the current review, and 20 additional references were also included on the basis of the authors' knowledge and/or on a review of the reference lists from relevant articles obtained through the literature search. Evidence supports the duration/frequency criterion for BED and the primary importance of loss of control and marked distress in identifying individuals with BED. Although overvaluation of shape/weight is not a diagnostic criterion, its relationship to the severity of BED psychopathology may identify a unique subset of individuals with BED. Additionally, individuals with BED often exhibit a clinical profile consisting of psychiatric (eg, mood, obsessive-compulsive, and impulsive disorders) and medical (eg, gastrointestinal symptoms, metabolic syndrome, and type 2 diabetes) comorbidities and behavioral profiles (eg, overconsumption of calories outside of a binge eating episode and emotional eating). Future revisions of the BED diagnostic criteria should consider the inclusion of BED subtypes, perhaps based on the overvaluation of shape/weight, and an evidence-based reassessment of severity criteria.

Abstract
Anorexia Nervosa (AN) is characterized by the maintenance of an undernourished, or starved, state. Persistent restrictive eating, or the recurrent intake of a diet that is inadequate to sustain a healthy weight, is the central behavior maintaining AN. To understand this disturbance, we need to understand the neural mechanisms that allow or promote the persistent choice of inadequate caloric intake. While a range of neural disturbances have been reported in AN, abnormalities in systems relevant to reward processing and the development of habit systems have been consistently described in both structural and functional neuroimaging studies. Most recently, brain and behavior have been directly examined by investigating the neural underpinnings of restrictive food choice. These recent data suggest that, among individuals with AN, dorsal frontostriatal circuits play a greater role in guiding decisions regarding what to eat than among healthy individuals. This line of research attempts to leverage advances in the field of cognitive neuroscience to further our understanding of persistent maladaptive choices of individuals with AN, in the hope that such advances will help in the development of novel treatments for this potentially fatal disorder.

Abstract
BACKGROUND The pursuit for healthy food consumption is considered a laudable habit. This attitude can turn into pathological when cognitions and worries about healthy nutrition lead to such an accurate food selection that correct diet becomes the most important part of one's own life leading to important dietary restrictions, stereotyped eating or impairment in important areas of functioning. This behaviour is coined orthorexia nervosa (ON) and can share common characteristics with anorexia nervosa (AN) and bulimia nervosa (BN). The purpose of the present study was to examine the frequency of ON among women with eating disorders (EDs) and to evaluate if it changed after treating the ED. METHODS Thirty-two patients with AN or BN were evaluated by means of the ORTO-15, the Yale-Brown-Cornell Eating Disorder Scale (YBC-EDS) and the Eating Attitude Test (EAT-26) before (t0) and 3 years after the treatment of their ED (t1), and compared to 32 female healthy controls (HC) matched by gender, age, and BMI at t1. RESULTS A significantly higher percentage of patients either at t0 (28 %) or t1 (58 %) resulted positive to ORTO-15 compared to controls (6 %). YBC-EDS and EAT-26 scores were higher among ED patients than in HC, but they decreased from t0 to t1. CONCLUSIONS Orthorexia nervosa symptoms are highly prevalent among patients with AN and BN, and tend to increase after treatment. ON seems associated both with the clinical improvement of AN and BN and the migration towards less severe forms of EDs. It is necessary to clarify if ON residual symptomatology can be responsible for a greater number of relapses and recurrences of EDs.

Abstract
This study sought to examine risk and onset patterns in anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED). Women with AN (n=71), BN (n=66), BED (n=160) and non-psychiatric controls (n=323) were compared retrospectively on risk factors, symptom onset, and diagnostic migration. Eating disorder groups reported greater risk exposure than non-psychiatric controls. AN and BED differed on premorbid personality/behavioral problems, childhood obesity, and family overeating. Risk factors for BN were shared with AN and BED. Dieting was the most common onset symptom in AN, whereas binge eating was most common in BN and BED. Migration between AN and BED was rare, but more frequent between AN and BN and between BN and BED. AN and BED have distinct risk factors and onset patterns, while BN shares similar risk factors and onset patterns with both AN and BED. Results should inform future classification schemes and prevention programs.

Abstract
We encountered a patient who presented extreme weight loss and received an eating disorder diagnosis that was later identified as adrenal Cushing's syndrome. A 32-year-old woman with a 2-year history of an eating disorder was admitted to our psychiatric ward due to dehydration, malnutrition and low weight. Her height and body weight were 152.1 cm and 29.8 kg, respectively (body mass index: 12.8). Her other symptoms included a depressed mood, decreased interest, retardation and suicidal ideation. Standard medical cares were prescribed to treat the depressive symptoms and eating disorder, but the depressive episode and low body weight of the patient persisted. Computed tomography of the abdomen revealed an unexpected left adrenal gland tumor. Cushing's syndrome was diagnosed based on several endocrinological examinations. After an enucleation of the left adrenal gland tumor, the patient began eating, and her body weight increased gradually. Her body weight increased to 42.0-47.0 kg (body mass index: 18.2-20.3). Her mental and physical conditions had stabilized. This case suggests that adrenal Cushing's syndrome may resemble eating disorders.

Abstract
I present the thesis that 'being physiological,' i.e., analyzing eating under conditions that do not perturb, or minimally perturb, the organism's endogenous processes, should be a central goal of the neuroscience of eating. I describe my understanding of 'being physiological' based on [i] the central neural-network heuristic of CNS function that traces back to Cajal and Sherrington, [ii] research on one of the simpler problems in the neuroscience of eating, identification of endocrine signals that control eating. In this context I consider natural meals, physiological doses and ranges, and antagonist studies. Several examples involve CCK. Next I describe my view of the cutting edge in the molecular neuroscience of eating as it has evolved from the discovery of leptin signaling through the application of optogenetic and pharmacogenetic methods. Finally I describe some novel approaches that may advance the neuroscience of eating in the foreseeable future. I conclude that [i] the neuroscience of eating may soon be able to discern 'physiological' function in the operation of CNS networks mediating eating, [ii] the neuroscience of eating should capitalize on methods developed in other areas of neuroscience, e.g., improved methods to record and manipulate CNS function in behaving animals, identification of canonical regional circuits, use of population electrophysiology, etc., and [iii] subjective aspects of eating are crucial aspects of eating science, but remain beyond mechanistic understanding.

Adherence to the Mediterranean diet is inversely related to binge eating disorder in patients seeking a weight loss program. Clin Nutr 2014; 34:107-14. [PMID: 24559856 DOI: 10.1016/j.clnu.2014.02.001] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2013] [Revised: 01/07/2014] [Accepted: 02/01/2014] [Indexed: 11/28/2022]
Abstract
BACKGROUND & AIM The key factors influencing the development of Binge Eating Disorder (BED) are not well known. Adherence to the Mediterranean diet (MD) has been suspected to reduce the risk of several mental illnesses such as depression and anxiety. There are no existing studies that have examined the relationships between BED and MD. METHODS Cross-sectional study of 1472 participants (71.3% women; mean age: 44.8 ± 12.7) at high risk of BED. A MD score (MED-score) was derived from a validated food frequency questionnaire and BED by Binge Eating Scale questionnaire (BES). Body mass index, waist circumference and total body fat (%) were assessed by anthropometric measurements. RESULTS 376 (25.5%) cases of self reported BED were identified. 11.1% of participants had a good adherence to MD (MED-score ≥ 9). After adjustments for age, gender, nutritional status, education, and physical activity level, high MED-score was associated with lower odds for BED (odds ratios and 95% confidence intervals of a BED disorder for successive levels of MED-score were 1 (reference), 0.77 (0.44, 1.36), 0.66 (0.37, 1.15), 0.50 (0.26, 0.96), and 0.45 (0.22, 0.55) (P for trend: <0.01). Olive oil and nut consumption were associated with low risk of BED development whereas butter, cream, sweets and commercial bakery/sweets/cakes consumption increased the risk. We did not find a cumulative effect of depression and anxiety on MED-score in binge eaters. CONCLUSIONS These results demonstrate an inverse association between MD and the development of BED in a clinical setting among subjects at risk of BED. Therefore, we should be cautious about generalizing the results to the whole population, although reverse causality and confounding cannot be excluded as explanation. Further prospective studies are warranted.

Eating disorders in schizophrenia: implications for research and management. SCHIZOPHRENIA RESEARCH AND TREATMENT 2014; 2014:791573. [PMID: 25485152 PMCID: PMC4251071 DOI: 10.1155/2014/791573] [Citation(s) in RCA: 38] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 06/16/2014] [Accepted: 11/03/2014] [Indexed: 01/23/2023]
Abstract
Objective. Despite evidence from case series, the comorbidity of eating disorders (EDs) with schizophrenia is poorly understood. This review aimed to assess the epidemiological and clinical characteristics of EDs in schizophrenia patients and to examine whether the management of EDs can be improved. Methods. A qualitative review of the published literature was performed using the following terms: "schizophrenia" in association with "eating disorders," "anorexia nervosa," "bulimia nervosa," "binge eating disorder," or "night eating syndrome." Results. According to our literature review, there is a high prevalence of comorbidity between schizophrenia and EDs. EDs may occur together with or independent of psychotic symptoms in these patients. Binge eating disorders and night eating syndromes are frequently found in patients with schizophrenia, with a prevalence of approximately 10%. Anorexia nervosa seems to affect between 1 and 4% of schizophrenia patients. Psychopathological and neurobiological mechanisms, including effects of antipsychotic drugs, should be more extensively explored. Conclusions. The comorbidity of EDs in schizophrenia remains relatively unexplored. The clearest message of this review is the importance of screening for and assessment of comorbid EDs in schizophrenia patients. The management of EDs in schizophrenia requires a multidisciplinary approach to attain maximized health outcomes. For clinical practice, we propose some recommendations regarding patient-centered care.

Abstract
In numerous pathological states, the brain can restrict food intake to a lethal level despite mounting requirements for energy as seen in adolescents with anorexia nervosa. How the brain reduces food intake to the point of death while eating is a cornerstone of survival that remains just as ‘cryptic’ as the association between anorexia and overeating. This review provides a recent snapshot of the neural underpinnings of the rewarding effects of anorexia that may compete with the adaptive decision-making process to eat, and with survival instinct. Among a plethora of factors, impaired activity of the serotonin receptors in the reward system underlies the ability of animals to self-impose food restriction, and the transition from under- to over-eating. However, the triumvirate association between serotonin, overeating and addiction appears unlikely. Considering the implication of the serotonin receptors in the hypothalamus, anorexia and bulimia nervosa could result from an impairment of a ‘synchronic activity’ between the autonomic and voluntary nervous systems.
