RESUMO
OBJECTIVE: Eating disorders are associated with significant illness burden and costs, yet access to evidence-based care is limited. Greater use of programme-led and focused interventions that are less resource-intensive might be part of the solution to this demand-capacity mismatch. METHOD: In October 2022, a group of predominantly UK-based clinical and academic researchers, charity representatives and people with lived experience convened to consider ways to improve access to, and efficacy of, programme-led and focused interventions for eating disorders in an attempt to bridge the demand-capacity gap. RESULTS: Several key recommendations were made across areas of research, policy, and practice. Of particular importance is the view that programme-led and focused interventions are suitable for a range of different eating disorder presentations across all ages, providing medical and psychiatric risk are closely monitored. The terminology used for these interventions should be carefully considered, so as not to imply that the treatment is suboptimal. CONCLUSIONS: Programme-led and focused interventions are a viable option to close the demand-capacity gap for eating disorder treatment and are particularly needed for children and young people. Work is urgently needed across sectors to evaluate and implement such interventions as a clinical and research priority.

AIM: To assess the extent of the scientific literature on avoidant/restrictive food intake disorder (ARFID) in children and young people with autism in order to evaluate and synthesize the evidence on (a) the nature of feeding and eating difficulties in children and young people with autism; (b) the consequences of a severely restricted diet; and (c) what is known about effective treatment approaches. METHOD: PubMed and PsycInfo databases were searched, identifying 56 studies and a narrative synthesis was effected. RESULTS: The literature suggested that ARFID-like presentations are common in children and young people with autism, with severe consequences for physical and mental health. The three drivers mentioned in the DSM-5 criteria, namely a sensory-based avoidance, fear- or phobia-based restriction, and a lack of interest in eating, are present in this population, although sensory sensitivities are currently the most commonly described. Research suggests that ARFID symptoms in children and young people with autism can be amenable to treatment, with evidence that behavioural interventions are feasible and potentially effective in this population. INTERPRETATION: ARFID is a common and impactful problem among young people with autism but is currently under researched. Work is required to (a) identify the prevalence of ARFID in children and young people with autism; (b) uncover the key drivers of ARFID in this population; (c) adapt currently available interventions for use with children and young people with autism; and (d) rigorously test these interventions in clinical trials. WHAT THIS PAPER ADDS: Significant food restriction is common in children and young people with autism. Sensory sensitivities are frequently cited as a reason for food restriction. The prevalence and causes of avoidant/restrictive food disorders in children and young people with autism need further research.

OBJECTIVE: There is a paucity of validated diagnostic interviews for avoidant/restrictive food intake disorder (ARFID) to aid identification and classification of cases for both clinical and research purposes. To evaluate the factor structure, construct validity, and criterion validity of the Pica ARFID and Rumination Disorder Interview (PARDI; ARFID module), we administered the PARDI to 129 children and adolescents ages 9-23 years (M = 16.1) with ARFID (n = 84), subclinical ARFID (n = 11), and healthy controls (n = 34). METHOD: We used exploratory factor analysis to examine the factor structure of the PARDI in children, adolescents, and young adults with an ARFID diagnosis, the Kruskal-Wallis analysis of variance and Spearman correlations to test the construct validity of the measure, and non-parametric receiver operating characteristic curves to evaluate the criterion validity of the PARDI. RESULTS: Exploratory factor analysis yielded a 3-factor structure: (1) concern about aversive consequences of eating, (2) low appetite/low interest in food, and (3) sensory sensitivity. Participants with ARFID demonstrated significantly higher levels of sensory sensitivity, low appetite/low-food interest, and concern about aversive consequences of eating symptoms relative to control participants. The construct validity for each PARDI subscale was supported and clinical cutoffs for the low appetite/low interest in food (1.1) and sensory sensitivity subscales (0.6) were established. DISCUSSION: These data present evidence for the factor structure and validity of the PARDI diagnostic interview for diagnosing ARFID in children, adolescents, and young adults, supporting the use of this tool to facilitate ARFID clinical assessment and research. PUBLIC SIGNIFICANCE: Due to the paucity of validated diagnostic interviews for avoidant/restrictive food intake disorder (ARFID), we evaluated the factor structure and validity of the Pica ARFID and Rumination Disorder Interview (ARFID module). Findings suggest that the interview assesses 3 components of ARFID: concern about aversive consequences of eating, low-appetite, and sensory sensitivity, and that clinical threshold scores on the latter two subscales can be used to advance ARFID assessment.

The prevalence of avoidant/restrictive food intake disorder (ARFID) in the general child population is still largely unknown and validated screening instruments are lacking. The aims of this study were (1) to investigate the prevalence of children screening positive for ARFID in a Japanese birth cohort using a newly developed parent-reported screening tool, (2) to estimate the prevalence of children with ARFID experiencing physical versus psychosocial consequences of their eating pattern, and (3) to provide preliminary evidence for the validity of the new screening tool. Data were collected from 3728 4-7-year-old children born between 2011 and 2014 in Kochi prefecture, Japan (response rate was 56.5%); a sub-sample of the Japan Environment and Children's Study (JECS). Parents completed a questionnaire including the ARFID screener and several other measures to assess convergent validity. The point prevalence of children screening positive for ARFID was 1.3%; half of them met criteria for ARFID based on psychosocial impairment alone, while the other half met diagnostic criteria relating to physical impairment (and additional psychosocial impairment in many cases). Sensory sensitivity to food characteristics (63%) and/or lack of interest in eating (51%) were the most prevalent drivers of food avoidance. Children screening positive for ARFID were lighter in weight and shorter in height, they showed more problem behaviors related to mealtimes and nutritional intake, and they were more often selective eaters and more responsive to satiety, which together provides preliminary support for the validity of the new screening tool. This is the largest screening study to date of ARFID in children up to 7 years. Future studies should examine the diagnostic validity of the new ARFID screener using clinically ascertained cases. Further research on ARFID prevalence in the general population is needed.

OBJECTIVE: Previous literature shows an increased risk for eating disorders in autistic individuals. This study tested whether fussy eating contributes to the association between childhood autistic traits and adolescent eating disorder behaviours. METHOD: Using data from the Avon Longitudinal Study of Parents and Children, we estimated the intercept and slope of parent-rated autistic traits and fussy eating between 7 and 14 years (N = 8982) and their association with self-reported eating disorder behaviours at age 14 years, including the indirect path from autistic traits to eating disorder behaviours via fussy eating. Analyses were adjusted for child sex, maternal age at delivery, maternal body mass index and maternal education. RESULTS: Analyses found a small indirect pathway from autistic traits intercept to eating disorder behaviours via fussy eating slope (b = 0.017, 95% CI = 0.002-0.032, p = 0.026), with higher levels of autistic traits at age 7 years being associated with a shallower decline in fussy eating, which in turn was associated with greater eating disorder behaviours. CONCLUSION: Findings point towards fussy eating as a potential link between childhood autistic traits and later disordered eating. Addressing fussy eating patterns before they become entrenched may decrease risk for eating disorders later in development.

BACKGROUND: Child eating behaviors are highly heterogeneous and their longitudinal impact on childhood weight is unclear. The objective of this study was to characterize eating behaviors during the first 10 years of life and evaluate associations with BMI at age 11 years. METHOD: Data were parental reports of eating behaviors from 15 months to age 10 years (n = 12,048) and standardized body mass index (zBMI) at age 11 years (n = 4884) from the Avon Longitudinal Study of Parents and Children. Latent class growth analysis was used to derive latent classes of over-, under-, and fussy-eating. Linear regression models for zBMI at 11 years on each set of classes were fitted to assess associations with eating behavior trajectories. RESULTS: We identified four classes of overeating; "low stable" (70%), "low transient" (15%), "late increasing" (11%), and "early increasing" (6%). The "early increasing" class was associated with higher zBMI (boys: ß = 0.83, 95% CI: 0.65, 1.02; girls: ß = 1.1; 0.92, 1.28) compared with "low stable." Six classes were found for undereating; "low stable" (25%), "low transient" (37%), "low decreasing" (21%), "high transient" (11%), "high decreasing" (4%), and "high stable" (2%). The latter was associated with lower zBMI (boys: ß = -0.79; -1.15, -0.42; girls: ß = -0.76; -1.06, -0.45). Six classes were found for fussy eating; "low stable" (23%), "low transient" (15%), "low increasing" (28%), "high decreasing" (14%), "low increasing" (13%), and "high stable" (8%). The "high stable" class was associated with lower zBMI (boys: ß = -0.49; -0.68-0.30; girls: ß = -0.35; -0.52, -0.18). CONCLUSIONS: Early increasing overeating during childhood is associated with higher zBMI at age 11. High persistent levels of undereating and fussy eating are associated with lower zBMI. Longitudinal trajectories of eating behaviors may help identify children potentially at risk of adverse weight outcomes.

BACKGROUND: Eating behaviours in childhood are considered as risk factors for eating disorder behaviours and diagnoses in adolescence. However, few longitudinal studies have examined this association. AIMS: We investigated associations between childhood eating behaviours during the first ten years of life and eating disorder behaviours (binge eating, purging, fasting and excessive exercise) and diagnoses (anorexia nervosa, binge eating disorder, purging disorder and bulimia nervosa) at 16 years. METHOD: Data on 4760 participants from the Avon Longitudinal Study of Parents and Children were included. Longitudinal trajectories of parent-rated childhood eating behaviours (8 time points, 1.3-9 years) were derived by latent class growth analyses. Eating disorder diagnoses were derived from self-reported, parent-reported and objectively measured anthropometric data at age 16 years. We estimated associations between childhood eating behaviours and eating disorder behaviours and diagnoses, using multivariable logistic regression models. RESULTS: Childhood overeating was associated with increased risk of adolescent binge eating (risk difference, 7%; 95% CI 2 to 12) and binge eating disorder (risk difference, 1%; 95% CI 0.2 to 3). Persistent undereating was associated with higher anorexia nervosa risk in adolescent girls only (risk difference, 6%; 95% CI, 0 to 12). Persistent fussy eating was associated with greater anorexia nervosa risk (risk difference, 2%; 95% CI 0 to 4). CONCLUSIONS: Our results suggest continuities of eating behaviours into eating disorders from early life to adolescence. It remains to be determined whether childhood eating behaviours are an early manifestation of a specific phenotype or whether the mechanisms underlying this continuity are more complex. Findings have the potential to inform preventative strategies for eating disorders.

Individual-level longitudinal data on biological, behavioural, and social dimensions are becoming increasingly available. Typically, these data are analysed using mixed effects models, with the result summarised in terms of an average trajectory plus measures of the individual variations around this average. However, public health investigations would benefit from finer modelling of these individual variations which identify not just one average trajectory, but several typical trajectories. If evidence of heterogeneity in the development of these variables is found, the role played by temporally preceding (explanatory) variables as well as the potential impact of differential trajectories may have on later outcomes is often of interest. A wide choice of methods for uncovering typical trajectories and relating them to precursors and later outcomes exists. However, despite their increasing use, no practical overview of these methods targeted at epidemiological applications exists. Hence we provide: (a) a review of the three most commonly used methods for the identification of latent trajectories (growth mixture models, latent class growth analysis, and longitudinal latent class analysis); and (b) recommendations for the identification and interpretation of these trajectories and of their relationship with other variables. For illustration, we use longitudinal data on childhood body mass index and parental reports of fussy eating, collected in the Avon Longitudinal Study of Parents and Children.

BACKGROUND: The World Health Organization (WHO) International Classification of Diseases and Related Health Problems (ICD) is used globally by 194 WHO member nations. It is used for assigning clinical diagnoses, providing the framework for reporting public health data, and to inform the organization and reimbursement of health services. Guided by overarching principles of increasing clinical utility and global applicability, the 11th revision of the ICD proposes major changes that incorporate empirical advances since the previous revision in 1992. To test recommended changes in the Mental, Behavioral, and Neurodevelopmental Disorders chapter, multiple vignette-based case-controlled field studies have been conducted which examine clinicians' ability to accurately and consistently use the new guidelines and assess their overall clinical utility. This manuscript reports on the results from the study of the proposed ICD-11 guidelines for feeding and eating disorders (FEDs). METHOD: Participants were 2288 mental health professionals registered with WHO's Global Clinical Practice Network. The study was conducted in Chinese, English, French, Japanese, and Spanish. Clinicians were randomly assigned to apply either the ICD-11 or ICD-10 diagnostic guidelines for FEDs to a pair of case vignettes designed to test specific clinical questions. Clinicians selected the diagnosis they thought was correct for each vignette, evaluated the presence of each essential feature of the selected diagnosis, and the clinical utility of the diagnostic guidelines. RESULTS: The proposed ICD-11 diagnostic guidelines significantly improved accuracy for all FEDs tested relative to ICD-10 and attained higher clinical utility ratings; similar results were obtained across all five languages. The inclusion of binge eating disorder and avoidant-restrictive food intake disorder reduced the use of residual diagnoses. Areas needing further refinement were identified. CONCLUSIONS: The proposed ICD-11 diagnostic guidelines consistently outperformed ICD-10 in distinguishing cases of eating disorders and showed global applicability and appropriate clinical utility. These results suggest that the proposed ICD-11 guidelines for FEDs will help increase accuracy of public health data, improve clinical diagnosis, and enhance health service organization and provision. This is the first time in the revision of the ICD that data from large-scale, empirical research examining proposed guidelines is completed in time to inform the final diagnostic guidelines.

OBJECTIVE: Avoidant/restrictive food intake disorder (ARFID), pica, and rumination disorder (RD) were added to the revised DSM-5 Feeding and Eating Disorders chapter in 2013. We developed a structured interview-the Pica, ARFID, and Rumination Disorder Interview (PARDI)-to assess the presence and severity of these diagnoses for evaluation and treatment planning in clinical and research settings. Here, we describe the development of the PARDI and provide a preliminary report on feasibility, acceptability, reliability, and validity in relation to ARFID. METHOD: We created an initial item pool from existing measures of similar constructs and clinical experience. The PARDI includes items assessing the level of endorsement and overall severity of common ARFID features organized into profiles (i.e., sensory sensitivity, lack of interest in eating, and fear of aversive consequences) and algorithms for diagnosing ARFID, pica, and RD. We collected initial psychometric data from participants (10-22 years) with ARFID (n = 39), clinically significant avoidant/restrictive eating (n = 8), and healthy controls (n = 10). RESULTS: On average, the PARDI took 39 min to complete and was acceptable to participants. All subscales achieved internal consistency greater ≥0.77, and inter-rater reliability for the ARFID diagnosis was moderate (κ = 0.75). Individuals with ARFID scored significantly higher than healthy controls on ARFID severity and ARFID profiles. DISCUSSION: The PARDI appears acceptable to respondents and preliminary evidence of reliability and validity has been demonstrated in an initial sample. Larger-scale validation studies are currently underway. The PARDI is freely available to clinicians and researchers.

OBJECTIVE: Since its introduction to the psychiatric nomenclature in 2013, research on avoidant/restrictive food intake disorder (ARFID) has proliferated highlighting lack of clarity in how ARFID is defined. METHOD: In September 2018, a small multi-disciplinary pool of international experts in feeding disorder and eating disorder clinical practice and research convened as the Radcliffe ARFID workgroup to consider operationalization of DSM-5 ARFID diagnostic criteria to guide research in this disorder. RESULTS: By consensus of the Radcliffe ARFID workgroup, ARFID eating is characterized by food avoidance and/or restriction, involving limited volume and/or variety associated with one or more of the following: weight loss or faltering growth (e.g., defined as in anorexia nervosa, or by crossing weight/growth percentiles); nutritional deficiencies (defined by laboratory assay or dietary recall); dependence on tube feeding or nutritional supplements (≥50% of daily caloric intake or any tube feeding not required by a concurrent medical condition); and/or psychosocial impairment. CONCLUSIONS: This article offers definitions on how best to operationalize ARFID criteria and assessment thereof to be tested in existing clinical populations and to guide future study to advance understanding and treatment of this heterogeneous disorder.

BACKGROUND: Evidence-based practice in eating disorders incorporates three essential components: research evidence, clinical expertise, and patient values, preferences, and characteristics. Conceptualized as a 'three-legged stool' by Sackett et al. in 1996 (BMJ), all of these components of evidence-based practice are considered essential for providing optimal care in the treatment of eating disorders. However, the extent to which these individual aspects of evidence-based practice are valued among clinicians and researchers is variable, with each of these stool 'legs' being neglected at times. As a result, empirical support and patient preferences for treatment are not consistently considered in the selection and implementation of eating disorder treatment. In addition, clinicians may not have access to training to provide treatments supported by research and preferred by patients. Despite these challenges, integrating these three components of evidence-based practice is critical for the effective treatment of eating disorders. DISCUSSION: Current research supports the use of several types of psychotherapies, including cognitive-behavioral, interpersonal, and family-based therapies, as well as certain types of medications for the treatment of eating disorders. However, limitations in current research, including sample heterogeneity, inconsistent efficacy, a paucity of data, the need for tailored approaches, and the use of staging models highlight the need for clinical expertise. Although preliminary data also support the importance of patient preferences, values, and perspectives for optimizing treatment, enhancing treatment outcome, and minimizing attrition among patients with eating disorders, the extent to which patient preference is consistently predictive of outcome is less clear and requires further investigation. All three components of evidence-based practice are integral for the optimal treatment of eating disorders. Integrating clinical expertise and patient perspective may also facilitate the dissemination of empirically-supported and emerging treatments as well as prevention programs. Further research is imperative to identify ways in which this three-legged approach to eating disorder treatment could be most effectively implemented.

OBJECTIVE: Few published studies have evaluated the clinical utility of new diagnostic criteria for avoidant/restrictive food intake disorder (ARFID), a DSM-5 reformulation of feeding and eating disorder of infancy or early childhood. We examined the prevalence of ARFID and inter-rater reliability of its diagnostic criteria in a pediatric gastrointestinal sample. METHOD: We conducted a retrospective chart review of 2,231 consecutive new referrals (ages 8-18 years) to 19 Boston-area pediatric gastroenterology clinics for evidence of DSM-5 ARFID. RESULTS: We identified 33 (1.5%) ARFID cases; 22 of whom (67%) were male. Most were characterized by insufficient intake/little interest in feeding (n = 19) or limited diet due to sensory features of the food (n = 7). An additional 54 cases (2.4%) met one or more ARFID criteria but there was insufficient information in the medical record to confer or exclude the diagnosis. Diagnostic agreement between coders was adequate (κ = 0.72). Common challenges were (i) distinguishing between diagnoses of ARFID and anorexia nervosa or anxiety disorders; (ii) determination of whether the severity of the eating/feeding disturbance was sufficient to warrant diagnosis in the presence of another medical or psychiatric disorder; and (iii) assessment of psychosocial impairment related to eating/feeding problems. DISCUSSION: In a pediatric treatment-seeking sample where ARFID features were common, cases meeting full criteria were rare, suggesting that the diagnosis is not over-inclusive even in a population where eating/feeding difficulties are expected.

BACKGROUND: Prompt access to evidence-based treatment for children and young people with eating disorders is important for outcomes, yet the gap in service provision remains pervasive. Record levels of young people are waiting for eating disorder treatment and access to care is limited. Guided self-help interventions that are brief and require minimal clinician support have the potential to meet the unprecedented demand for treatment quickly and effectively. OBJECTIVE: To examine the feasibility, acceptability and proof of concept of a novel, CBT guided self-help intervention for children and young people with threshold and subthreshold eating disorders. METHODS: A single-arm, proof-of-concept pilot study of the CBT guided self-help intervention will be conducted. Children and young people (aged 11-19) with threshold and subthreshold eating disorders will receive a self-help intervention covering the core components of CBT, supported by 8 weekly guidance sessions delivered remotely. Clinical outcomes (eating-related psychopathology and associated impairment, changes in weight, depression, anxiety, and behavioural difficulties) will be assessed at baseline and post-intervention (12 weeks). Feasibility and acceptability of the intervention will be measured using various outcomes, including adherence to, and engagement with the intervention, rates of recruitment and retention, measure completion and treatment satisfaction. Qualitative data will also be collected for future intervention refinement. DISCUSSION: If the intervention is shown to produce clinical benefits in this pilot study, a fully powered randomised pilot study will be warranted with the ultimate goal of increasing access to psychological treatment for children and young people threshold and subthreshold eating disorders. ADMINISTRATIVE INFORMATION: This study protocol (S1 File) adheres to the guidelines outlined in the Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) checklist for trial protocols [1, 2] which can be found in S1 Checklist. The numbers in parentheses in this protocol correspond to the item numbers in the SPIRIT checklist. The order of items has been modified to group similar items.

Avoidant/restrictive food intake disorder (ARFID) is a new diagnostic category in DSM-5. Although replacing Feeding Disorder of Infancy or Early Childhood, it is not restricted to childhood presentations. In keeping with the broader aim of revising and updating criteria and text to better reflect lifespan issues and clinical expression across the age range, ARFID is a diagnosis relevant to children, adolescents, and adults. This case example of a 13-year old boy with ARFID illustrates key issues in diagnosis and treatment planning. The issues discussed are not exhaustive, but serve as a guide for central diagnostic and treatment issues to be considered by the clinician. It is anticipated that the inclusion of specific criteria for ARFID as a category within Feeding and Eating Disorders in DSM-5 will stimulate research into its typology, prevalence, and incidence in different populations and facilitate the development of effective, evidence-based interventions for this patient group.

Background: ARFID (avoidant restrictive food intake disorder) is a relatively new diagnostic term covering a number of well-recognised, clinically significant disturbances in eating behaviour unrelated to body weight/shape concerns. Its phenotypic heterogeneity combined with much about the condition remaining unknown, can contribute to uncertainties about best practice. While other reviews of the evidence base for ARFID exist, few specifically target health care professionals and implications for clinical practice. Methods: A narrative review was conducted to synthesise the findings of ARFID papers in scientific journals focussing on four key areas relevant to clinical practice: prevalence, assessment and characterisation of clinical presentations, treatment, and service delivery. Freely available online databases were searched for case studies and series, research reports, review articles, and meta-analyses. Findings were reviewed and practice implications considered, resulting in proposed clinical recommendations and future research directions. Results: We discuss what is currently known about the four key areas included in this review. Based on available evidence as well as gaps identified in the literature, recommendations for clinical practice are derived and practice-related research priorities are proposed for each of the four of the areas explored. Conclusion: Prevalence studies highlight the need for referral and care pathways to be embedded across a range of health care services. While research into ARFID is increasing, further studies across all areas of ARFID are required and there remains a pressing need for guidance on systematic assessment, evidence-based management, and optimal service delivery models. Informed clinical practice is currently predominantly reliant on expert consensus and small-scale studies, with ongoing routine clinical data capture, robust treatment trials and evaluation of clinical pathways all required. Despite this, a number a positive practice points emerge.
RESUMO
This study aimed to investigate the prevalence of childhood picky eating (PE) and to identify risk factors associated with different PE trajectories using data from the Growing up in Scotland research survey. PE was operationalised using three items across three study sweeps, at ages 2, 5 and 10 years respectively. We found 13.5 % of children with PE at age 2, 22.2 % at age 5, and 6.4 % at age 10. From these, we defined three PE categories: transient PE in early childhood (23.3 %), persistent PE into late childhood (3.7 %) and PE absent (73.0 %). Using multinomial logistic regression, we investigated associations between child and family characteristics and transient and persistent PE, adjusting for potential confounders. Various factors were associated with increased risk of persistent pickiness, including mothers who smoked during pregnancy and children whose mothers reported feeding challenges at 9-12 months. These findings support the view that PE behaviours are common and tend to remit by adolescence although a small number of children are at risk of experiencing longer term problems. Families of children who are exposed to such risks may benefit from preventative interventions.

BACKGROUND: Feeding and eating disorders are associated with significant illness burden and costs, yet access to evidence-based care is limited. Low intensity psychological interventions have the potential to increase such access. METHODS: A systematic review and meta-analysis were conducted on the use of low intensity psychological interventions for the treatment of feeding and eating disorders. Studies comparing low intensity psychological interventions against high intensity therapies and non-eating disorder specific psychological interventions were included, as well as those with waiting list control arms. There were three primary outcomes: eating disorder psychopathology, diagnostic and statistical manual of mental disorders (DSM) severity specifier-related outcomes and rates of remission/recovery. RESULTS: Thirty-three studies met the inclusion criteria, comprising 3665 participants, and 30 studies were included in the meta-analysis. Compared to high intensity therapies, low intensity psychological interventions were equivalent on reducing eating disorder psychopathology (g = - 0.13), more effective at improving DSM severity specifier-related outcomes (g = - 0.15), but less likely to achieve remission/recovery (risk ratio (RR) = 0.70). Low intensity psychological interventions were superior to non-eating disorder specific psychological interventions and waiting list controls across all three primary outcomes. CONCLUSION: Overall, findings suggest that low intensity psychological interventions can successfully treat eating disorder symptoms. Few potential moderators had a statistically significant effect on outcome. The number of studies for many comparisons was low and the methodological quality of the studies was poor, therefore results should be interpreted with caution. More research is needed to establish the effectiveness of low intensity psychological interventions for children and young people, as well as for individuals with anorexia nervosa, avoidant/restrictive food intake disorder, pica and rumination disorder.
Feeding and eating disorders can significantly impair health and psychosocial functioning. However, demand for eating disorder services is greater than services' ability to deliver effective treatment. Low intensity psychological interventions, which are brief in nature and require less therapist input than standard treatments, have the potential to bridge this demand-capacity gap. The current review examined the effectiveness of low intensity psychological interventions for the treatment of feeding and eating disorders. Overall, findings suggest that low intensity psychological interventions can successfully treat eating disorder symptoms, particularly binge eating-related symptoms. Given their relatively low costs and ease of accessibility, such interventions can help people to access treatment at a time when this is so desperately needed. More research is needed to determine the value of low intensity psychological interventions for children and adolescents, and people with feeding and eating disorders that are not characterised by recurrent binge eating, such as anorexia nervosa, ARFID, pica and rumination disorder.
RESUMO
Background: Avoidant restrictive food intake disorder (ARFID) is a new eating disorder with a heterogeneous clinical presentation. It is unclear which patient characteristics contribute to its heterogeneity. Methods: To identify these patient characteristics, we performed symptom-level correlation and driver-level regression analyses in our cross-sectional study in up to 261 ARFID patients (51% female; median age = 12.7 years) who were assessed at the Maudsley Centre for Child and Adolescent Eating Disorders, London between November 2019 and July 2022. Findings: Symptoms across the three drivers 1) avoidance based on sensory characteristics of food; 2) apparent lack of interest in eating; and 3) concern about aversive consequences positively correlated with each other. Patients' anxiety traits showed the greatest positive correlations with symptoms of concern about aversive consequences of eating. Patient sex was not significantly associated with any of the three ARFID drivers. Patients with comorbid autism spectrum disorder (ASD; 28%) showed more food-related sensory sensitivities (RR = 1.26) and greater lack of interest in eating (RR = 1.18) than those of patients without ASD (49%). Interpretation: In our clinical sample, the ARFID drivers occurred together and did not show clinically meaningful differences between the sexes. ASD may accentuate food-related sensory sensitivities and lack of interest, but may not drive a completely different symptom presentation. ARFID is multi-faceted and heterogenous, requiring a comprehensive multidisciplinary assessment to sufficiently understand the drivers of the restrictive eating behaviour. Results need replication in larger samples with more statistical power. Funding: None.
RESUMO
OBJECTIVE: To investigate whether young people (8-16 years) with an eating disorder have a higher prevalence of autism spectrum disorder (ASDs) and elevated autistic traits compared to typically developing (TD) peers. METHOD: Twenty-two participants with early onset eating disorder (EOED) were assessed using standardized ASD measures and compared to IQ matched TD (n = 24) and ASD (n = 20) controls. RESULTS: An ASD diagnosis was no more common in EOED than in TD controls. However, repetitive and stereotyped behavior was more often observed in the EOED group and, compared to TD controls, there was a trend (p = .07) toward greater autistic social impairment in EOED. DISCUSSION: Whilst participants with EOED did not show increased ASD prevalence, they did have elevated autistic traits of clinical significance, particularly repetitive and stereotyped behavior. Further work is required to determine whether inflexibility and social difficulties in EOED have identical phenomenology and etiology to those seen in ASD.
