Diagnosis Of Avoidant/restrictive Food Intake Disorder Research Articles

Avoidant/Restrictive Food Intake Disorder: Review and Recent Advances.

Avoidant/restrictive food intake disorder (ARFID) is an eating disorder recently codified in DSM-5 that affects individuals of all ages. A proliferation of ARFID research has emerged over the years, and this review provides a brief overview of the current understanding of ARFID epidemiology, symptoms, comorbid conditions, assessment, and treatment. The review highlights recent research updates regarding ARFID among adults, putative neurobiological mechanisms underlying ARFID, and new treatment trials. Findings from this review demonstrate that ARFID is as prevalent as other eating disorders, even among adults, and is associated with significant medical and psychiatric comorbid conditions. New, promising treatments for children, adolescents, and adults are in the early stages of development. Several assessments are now available to aid in the screening and diagnosis of ARFID and have demonstrated cross-cultural validity. Areas for future research and clinical guidance, including unresolved questions regarding ARFID categorization and differential diagnosis, are discussed.

Latent profile analysis reveals overlapping ARFID and shape/weight motivations for restriction in eating disorders.

DSM-5 differentiates avoidant/restrictive food intake disorder (ARFID) from other eating disorders (EDs) by a lack of overvaluation of body weight/shape driving restrictive eating. However, clinical observations and research demonstrate ARFID and shape/weight motivations sometimes co-occur. To inform classification, we: (1) derived profiles underlying restriction motivation and examined their validity and (2) described diagnostic characterizations of individuals in each profile to explore whether findings support current diagnostic schemes. We expected, consistent with DSM-5, that profiles would comprise individuals endorsing solely ARFID or restraint (i.e. trying to eat less to control shape/weight) motivations. We applied latent profile analysis to 202 treatment-seeking individuals (ages 10-79 years [M = 26, s.d. = 14], 76% female) with ARFID or a non-ARFID ED, using the Nine-Item ARFID Screen (Picky, Appetite, and Fear subscales) and the Eating Disorder Examination-Questionnaire Restraint subscale as indicators. A 5-profile solution emerged: Restraint/ARFID-Mixed (n = 24; 8% [n = 2] with ARFID diagnosis); ARFID-2 (with Picky/Appetite; n = 56; 82% ARFID); ARFID-3 (with Picky/Appetite/Fear; n = 40; 68% ARFID); Restraint (n = 45; 11% ARFID); and Non-Endorsers (n = 37; 2% ARFID). Two profiles comprised individuals endorsing solely ARFID motivations (ARFID-2, ARFID-3) and one comprising solely restraint motivations (Restraint), consistent with DSM-5. However, Restraint/ARFID-Mixed (92% non-ARFID ED diagnoses, comprising 18% of those with non-ARFID ED diagnoses in the full sample) endorsed ARFID and restraint motivations. The heterogeneous profiles identified suggest ARFID and restraint motivations for dietary restriction may overlap somewhat and that individuals with non-ARFID EDs can also endorse high ARFID symptoms. Future research should clarify diagnostic boundaries between ARFID and non-ARFID EDs.

Psychological and Sociological Influences Contributing to Avoidant Restrictive Food Intake Disorder (ARFID) Across Age Groups and Gender

This review depicts the epidemiology of avoidant restrictive food intake disorder (ARFID), a relatively new eating disorder characterized by persistent food restriction leading to weight loss or nutritional deficiencies. The prevalence of ARFID varies, with the disorder occurring in both children and adults, although rates may be higher among females. Psychopathological, medical, neurodevelopmental, family, genetic, and cultural factors may contribute to the development of ARFID. The media can significantly impact the development and persistence of ARFID, both positively and negatively. This review also discusses diagnostic criteria and differential diagnosis of ARFID. Assessment tools and evaluation protocols are described, such as clinical, physical, psychiatric, psychological, and functional magnetic resonance imaging (fMRI). Finally, the review covers various treatment options for ARFID, like cognitive-behavioral therapy (CBT), nutritional interventions, family-based therapy (FBT), and pharmacotherapy. The challenges in the diagnosis and treatment of ARFID are also highlighted, including overlapping symptomatology with other mental health disorders and heterogeneous manifestations of the disorder.

Exploring Family Care Journeys to Inform Cognitive-Behavioral Therapy for Avoidant/Restrictive Food Intake Disorder and Somatic Symptom Disorders

Avoidant/restrictive food intake disorder (ARFID) and gastrointestinal (GI)-related somatic symptom and related disorders (SSRDs) commonly co-occur, and both are associated with confusion in the process of accessing treatment. Furthermore, health professionals report low confidence in providing care for these conditions. Using a life history methodology, we explored the journeys of children and their parents with the diagnosis and treatment of ARFID and/or SSRDs and examined themes in barriers and facilitators to care. Six families with children (4 boys and 2 girls; 8–14 years old) with a diagnosis of ARFID and/or GI-related SSRD were recruited from a pediatric tertiary-level hospital. Interviews were conducted with four parents alone, and two parent-child dyads. Participants provided rich histories of the child’s health journeys with variation in the development of ARFID and GI-related SSRDs and subsequent management. Diagnostic uncertainty, the emotional impact of this journey on families, and systemic barriers to accessing treatment were themes of the healthcare narratives. Validating the emotional impacts of the healthcare journey and building trust may be helpful to address the diagnostic uncertainty that families experience. Strategies to support adaptation of cognitive-behavioral approaches for with children with complex ARFID and/or SSRDs are discussed.

Birth-related, medical, and diagnostic characteristics in younger versus older children with avoidant/restrictive food intake disorder (ARFID)

BackgroundAlthough avoidant/restrictive food intake disorder (ARFID) presents the replacement and extension of feeding disorders of infancy and childhood, previous research into ARFID concentrated mainly on older patients. While birth-related characteristics play an etiologic role in feeding disorders, virtually nothing is known so far in ARFID. Therefore, the first aim of the study was to identify differences in birth-related characteristics in younger vs. older children with ARFID. Second, differences in physical and mental comorbidities, and third, diagnostic features between age groups were analysed.MethodsAmong N = 51 in- and outpatient treatment-seeking patients, n = 23 patients aged 0–5 years (30% girls) and n = 28 patients aged 6–17 years (57% girls), with an interview-based diagnosis of ARFID were included. Data on the pre- and perinatal period and mental and physical comorbidities were derived from patients’ medical records, while diagnostic criteria, main ARFID presentation, and sociodemographic variables were collected through diagnostic interview.ResultsSignificantly, younger patients with ARFID were born more often preterm and had more pre- and perinatal complications and a higher incidence of postnatal invasive procedures. Patients with ARFID aged 0–5 years presented significantly more physical comorbidities and conditions, especially congenital anomalies, while mental comorbidities, especially mood disorders, were significantly more common in patients with ARFID aged 6–17 years. No age differences were found for the distribution of diagnostic criteria and main ARFID presentation.ConclusionThis is the first study which aimed to identify age-specific characteristics in patients with ARFID with potential relevance for diagnosis and treatment. Especially birth-related complications, including invasive procedures postnatally, may be associated with developing ARFID, highlighting the importance of a closer view on these potential risk factors of the disorder. Future research with longitudinal design and larger samples may allow more detailed information on further age-specific associations, symptom trajectories, and age-specific risk factors for ARFID.

Modification of an inpatient medical management protocol for pediatric Avoidant/Restrictive Food Intake Disorder: improving the standard of care

BackgroundNo guidelines currently exist that represent a standardization of care for Avoidant/Restrictive Food Intake Disorder (ARFID) on an inpatient service. Unique features of this diagnosis (e.g., sensory sensitivity contributing to involuntary emesis) suggest that established protocols that were developed for anorexia nervosa might be less effective for adolescents with ARFID. To inform improved inpatient medical stabilization and care for these patients, we first provide an overview of clinical characteristics for patients with ARFID who presented to a pediatric hospital for inpatient eating disorder care. We use these descriptives to outline the rationale for, and executions of, modifications to an inpatient protocol designed to flexibly meet the needs of this clinical population.MethodsChart review with descriptive statistics were conducted for patients who had received an ARFID diagnosis from March 2019 to March 2023 (N = 32, aged 9–23). We then present a case series (n = 3) of adolescents who either transitioned to a novel adjusted protocol from an original standard of care on the inpatient service, or who received only the standard protocol.ResultsThe sample was aged M(SD) = 15.6 (3.3) years, 53% male, and a majority (69%) presented with the ARFID presentation specific to fear of negative consequences. On average, patients had deviated from their growth curve for just over two years and presented with mean 76% of their estimated body weight. Of those requiring nasogastric tube insertion during admission (n = 8, 25%), average duration of tube placement was 15 days. From within this sample, case series data suggest that the adjusted protocol will continue to have a positive impact on care trajectory among adolescents admitted for ARFID including improved weight gain, reduction of emesis, and improved food intake.ConclusionsFindings demonstrate the likely need to tailor established medical inpatient protocols for those with ARFID given different symptom presentation and maintenance factors compared to patients with anorexia nervosa. Further research is warranted to explore the longer-term impact of protocol changes and to inform standardization of care for this high priority clinical population across care sites.

Clinical features of adult patients with avoidant/restrictive food intake disorder presenting for medical stabilization: A descriptive study.

The purpose of this study is to describe the clinical features of adult patients with avoidant/restrictive food intake disorder (ARFID) to better understand the medical findings, psychological comorbidities, and laboratory abnormalities in this population. We completed a retrospective chart review of all adult patients with a diagnosis of ARFID, admitted for medical stabilization, between April 2016 and June 2021, to an inpatient hospital unit, which specializes in severe eating disorders. Information collected included anthropomorphic data, laboratory assessments, and medical history at time of admission. One hundred and twenty-two adult patients with ARFID were identified as meeting inclusion criteria for the study. The most common ARFID presentation was "fear of adverse consequences." The majority were female (70%), with an average age of 32.7 ± 13.7 years and mean percent of ideal body weight (m%IBW) of 68.2 ± 10.9. The most common laboratory abnormalities were low serum prealbumin and vitamin D, hypokalemia, leukopenia, and elevated serum bicarbonate. The most common psychiatric diagnoses were anxiety and depressive disorders, and the most common medical diagnoses were disorders of gut-brain interaction (DGBI). This is the largest study to the authors' knowledge of medical presentations in adult patients with ARFID. Our results reflect that the adult patient with ARFID may, in some aspects, present differently than pediatric and adolescent patients with ARFID, or from ARFID patients requiring less intensive care. This study highlights the need for further investigation of adult patients with ARFID. ARFID is a restrictive eating disorder first defined in 2013. This study explores the medical presentations of adult patients (>18 years old) with ARFID presenting for specialized eating disorder treatment and identifies unique features of the adult presentation for treatment, compared to pediatric and adolescent peers.

Avoidant restrictive food intake disorder and suicidal ideation

Most DSM-5 eating disorder diagnoses are associated with elevated suicide risk; however, little is known about the relationship between Avoidant/Restrictive Food Intake Disorder (ARFID) and suicidal ideation. The aim of the current study was to examine suicidal ideation within an adult ARFID sample. Patients with eating disorders (N = 936), some of whom met criteria for a current DSM-5 diagnosis of ARFID (n = 79), completed the Beck Depression Inventory II Item 9, regarding suicidal ideation. The study was conducted within an eating disorder treatment facility that offers inpatient, residential, partial hospitalization program, and intensive outpatient levels of care. Findings suggest no significant pairwise differences in suicidal ideation prevalence between participants with ARFID and those with any other ED diagnosis. Thorough screening for suicidal thoughts and risk among those with ARFID is warranted at all levels of care. We suggest that future research expand upon this work in a larger adult ARFID sample.

Validation study on the child, adult, and parent version of the ARFID module 2.0 for the Eating Disorder Examination.

This study presents a psychometric evaluation of the avoidant/restrictive food intake disorder (ARFID) module 2.0 for the Eating Disorder Examination (EDE), its child (ChEDE), and parent version. Within a pediatric sample seeking treatment for restrictive feeding or eating disorders and non-treatment-seeking controls, the module's interrater reliability, parent-child agreement, and its convergent, divergent, and discriminant validity were examined. The child, adult, and/or parent version of the German ARFID module was administered to N=176 children and adolescents (0-17 years) and their parents, as were the (Ch)EDE, well-established measures on food-avoidance behaviors, food variety, and body esteem, and objective anthropometric measures. Across all versions of the ARFID module, substantial to almost perfect interrater reliability was shown. Parent-child agreement for ARFID diagnosis was substantial. Based on medium-to-large associations between interview-assessed avoidant/restrictive food intake and questionnaire-assessed food-avoidance behaviors, food variety, and objective weight status, the module showed high convergent validity, especially for the child and parent version. Low associations of avoidant/restrictive food intake with weight and shape concern demonstrated divergent validity. Individuals with ARFID differed significantly from those with anorexia nervosa and individually matched controls in a range of clinical characteristics, indicating discriminant validity. This comprehensive validation supports the EDE ARFID module to be a valuable measure for the assessment and diagnosis of ARFID in 0-17-year-olds based on self- and parent-report. Validation of the ARFID module against other interview-based measures on ARFID and its evaluation in an adult sample are pending. Based on good reliability and validity of the avoidant/restrictive food intake disorder (ARFID) module for the Eating Disorder Examination (EDE) in its child, adult, and parent version, the present study paves the way for the clinical and research use of the interview-based EDE ARFID module for assessing ARFID across childhood and adolescence.

The factor structure and validity of a diagnostic interview for avoidant/restrictive food intake disorder in a sample of children, adolescents, and young adults.

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). 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. 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. 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. 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.

Prevalence and Characteristics of Avoidant/Restrictive Food Intake Disorder in Pediatric Neurogastroenterology Patients.

Recent reports document avoidant/restrictive food intake disorder (ARFID) symptoms among 13-40% of adults presenting to neurogastroenterology clinics, but ARFID in pediatrics is understudied. We conducted a retrospective review of charts from 129 consecutive referrals (ages 6-18 years; 57% female) for pediatric neurogastroenterology examination, from January 2016 through December 2018. Eleven cases (8%) met the full criteria for ARFID by the Diagnostic and Statistical Manual of Mental Disorders, 5th edition and 19 cases (15%) had clinically significant avoidant/ restrictive eating behaviors with insufficient information for a definitive ARFID diagnosis. Of patients with ARFID symptoms (n = 30), 20 (67%) cited fear of gastrointestinal symptoms as motivation for their avoidant/ restrictive eating. Compared to patients without ARFID symptoms, patients with ARFID symptoms were older (P < .001), more likely to be female (51% vs 79%, P = 0.014), and more frequently presented with eating/weight-related complaints (15% vs 33%, P = 0.026). This pilot retrospective study showed ARFID symptoms present in 23% of pediatric neurogastroenterology patients; further research is needed to understand risk and maintenance factors of ARFID in the neurogastroenterology setting.

Pediatric Avoidant-Restrictive Food Intake Disorder and gastrointestinal-related Somatic Symptom Disorders: Overlap in clinical presentation.

Certain presentations of Avoidant/Restrictive Food Intake Disorder (ARFID) and Somatic Symptom and Related Disorders (SSRDs) have conceptual overlap, namely, distress and impairment related to a physical symptom. This study compared characteristics of pediatric patients diagnosed with ARFID to those with gastrointestinal (GI)-related SSRD. A 5-year retrospective chart review at a tertiary care pediatric hospital comparing assessment data of patients with a diagnosis of ARFID (n = 62; 69% girls, Mage = 14.08 years) or a GI-related SSRD (n = 37; 68% girls, Mage = 14.25 years). Patients diagnosed with ARFID had a significantly lower percentage of median BMI than those with GI-related SSRD. Patients diagnosed with ARFID were most often assessed in the Eating Disorders Program, whereas patients diagnosed with an SSRD were most often assessed by Consultation-Liaison Psychiatry. Groups did not differ on demographics, psychiatric diagnoses, illness duration, or pre-assessment services/medications. GI symptoms were common across groups. Patients diagnosed with an SSRD had more co-occurring medical diagnoses. A subset (16%) of patients reported symptoms consistent with both diagnoses. Overlap is observed in the clinical presentation of pediatric patients diagnosed with ARFID or GI-related SSRD. Some group differences emerged, including anthropometric measurements and co-occurring medical conditions. Findings may inform diagnostic classification and treatment approach.

Falling Through the Cracks: UK Health Professionals’ Perspective of Diagnosis and Treatment for Children and Adolescents with Avoidant/Restrictive Food Intake Disorder

ABSTRACT Background Avoidant/restrictive food intake disorder (ARFID) describes an eating disturbance associated with weight loss or faltering growth in children, significant nutritional deficiency, reliance on oral supplements, reliance on enteral feeding and/or a clear interference with psychosocial functioning, in the absence of body image concerns. Seven years on from the introduction of the diagnostic criteria for ARFID anecdotal evidence suggests that health practitioners struggle to identify, diagnose and treat ARFID effectively. This study systematically investigates and categorises the different barriers to effective healthcare for children with ARFID, from the perspective of those who encounter and care for these children in their professional practice. Method A mixed methods online survey containing closed and open questions sought to gather information about paediatric healthcare for ARFID. Forty-five primary and secondary health-care professionals (HCPs) from 7 disciplines took part, providing information regarding their confidence in the identification and diagnosis of ARFID but also their confidence in making appropriate onward referrals and any barriers to effective healthcare for this patient population. Results The findings suggested that participating primary HCPs struggle to identify children with ARFID and if they do, they do not necessarily know who to refer these children to for assessment, diagnosis and support. Participating secondary, or specialist, HCPs felt more confident in their ability to identify a child with ARFID, but were similarly unsure about onward referrals. HCPs identified lack of professionals’ knowledge and training and a lack of clear pathways or specific services as barriers to effective diagnosis and treatment for this clinical group. Conclusion This study highlights the need for education and training for primary HCPs and the need for well-coordinated, multidisciplinary, ARFID-specific care pathways which can appropriately manage assessment, diagnosis and support of this often complex clinical group.

Avoidant/restrictive food intake disorder and autism spectrum disorder: clinical implications for assessment and management.

We examined clinical and neurodevelopmental presentations of children with avoidant/restrictive food intake disorder (ARFID) to inform clinical assessment and management. Five hundred and thirty-six patients (mean age 6y 10mo, SD 3y 5mo, range 10mo-20y; 401 males, 135 females) seen by the tertiary multidisciplinary feeding service at the Evelina London Children's Hospital between January 2013 and June 2019 were included in this case-control study. These children experienced significant feeding difficulties impacting nutrition, development, and psychosocial functioning requiring tertiary specialized input. Data on ARFID diagnosis, demographics, comorbidity, and nutrition was extracted from electronic patient records. Forty-nine per cent of children met ARFID criteria. The remaining participants had other difficulties including feeding, medical, and/or neurodevelopmental conditions. ARFID is more prevalent among younger patients (4-9 years) and in children with comorbid autism spectrum disorder (ASD). Younger age, comorbid ASD, and male sex significantly predicted ARFID. Diet range and male sex significantly predicted nutritional inadequacy, while comorbid ASD did not. A trend was seen between younger age and nutritional inadequacy. Young children with ARFID should raise suspicion for ASD. Although significant nutritional deficiencies are common in children with comorbid ARFID and ASD, they are correctable with nutritional supplementation. Specialty perspective potentially limits generalizability of findings to community feeding services. We also emphasize the importance of early identification of nutritional deficits and management.

The diagnosis of avoidant restrictive food intake disorder in the presence of gastrointestinal disorders: Opportunities to define shared mechanisms of symptom expression.

Individuals with a gastrointestinal (GI) disorder often alter their diet to manage GI symptoms, adding complexity to understanding the diverse motivations contributing to food avoidance/restriction. When a GI disorder is present, the DSM-5 states that Avoidant/Restrictive Food Intake Disorder (ARFID) can be diagnosed only when eating disturbance exceeds that expected. There is limited guidance to make this determination. This study attempts to address this gap by characterizing the presentation of ARFID in adults with and without a self-reported GI disorder. Participants were 2,610 adults ages 18-44 who self-identified as "picky eaters." Participants reported on motivations for food avoidance, affective experiences towards food, and perceived impairment. Responses were compared across four groups: GI issues and likely ARFID (L-ARFID/GI), L-ARFID-only, GI-only, and No-ARFID/No-GI. Groups with a GI disorder (L-ARFID/GI, GI-only) reported more fear of aversive consequences of eating than those without a GI disorder, while groups with L-ARFID (L-ARFID, L-ARFID/GI) evidenced significantly greater sensory aversion to food and indifference to food or eating, negative emotional reactions to food and overall disgust sensitivity, and eating related impairment. Consideration of the interplay of a GI disorder with ARFID can add precision to case conceptualization. Food avoidance may be attempts to manage fears of aversive consequences that are augmented by a history of GI symptoms, while sensory aversions and negative emotional reactions towards foods may be more elevated in ARFID. These findings emphasize the need to consider an ARFID diagnosis in patients with GI disorders to optimize care.

Five years of Avoidant/Restrictive Food Intake Disorder: no consensus of understanding among health professionals in New Zealand

ABSTRACT In 2013, Avoidant/Restrictive Food Intake Disorder (ARFID) was introduced as a new diagnosis. Prior 2013 there was great variability in professionals’ understanding of children’s food intake. Children with a restricted intake of food had limited recognition amongst health services, which the ARFID diagnosis aimed to change. Over time, it is useful to evaluate whether the formulation of this eating disorder has improved understanding of food refusal or ‘picky eating’ to ultimately enable effective outcomes for children and their families. This study explored changes in perspective from 2013 to 2018 regarding understanding of picky eating amongst health professionals (medical practitioners, dietitians and speech-language therapists) working with children and feeding difficulties in New Zealand. An online survey conducted in 2013 and 2018 targeted understanding of food refusal and consensus within the medical field for the labelling of picky eating. Responses were analysed with descriptive statistics, and qualitative content analysis. Health professionals in both years reported there was no consensus in the labelling of picky eating, with a significant increase in those reporting ‘no consensus’ in 2018 (n = 141, p = .035). However, health professionals demonstrated an increased awareness from 2013, by seeking further information regarding labelling of the condition portrayed. Despite an increase in awareness since 2013, health professionals are yet to agree on the diagnosis and treatment of ARFID. The impact of picky eating on parental stress may be underestimated in the literature. Consensus and guidelines are necessary to support health professionals, individuals and their families to obtain necessary services and resources.

Validation of the nine item ARFID screen (NIAS) subscales for distinguishing ARFID presentations and screening for ARFID.

The Nine Item Avoidant/Restrictive Food Intake Disorder (ARFID) Screen (NIAS) has three subscales aligned with ARFID presentations but clinically validated cutoff scores have not been identified. We aimed to examine NIAS subscale (picky eating, appetite, fear) validity to: (1) capture clinically-diagnosed ARFID presentations; (2) differentiate ARFID from other eating disorders (other-ED); and (3) capture ARFID symptoms among individuals with ARFID, individuals with other-ED, and nonclinical participants. Participants included outpatients (ages 10-76 years; 75% female) diagnosed with ARFID (n=49) or other-ED (n=77), and nonclinical participants (ages 22-68 years; 38% female, n=40). We evaluated criterion-related concurrent validity by conducting receiver operating curve (ROC) analyses to identify potential subscale cutoffs and by testing if cutoffs could capture ARFID with and without use of the Eating Disorder Examination-Questionnaire (EDE-Q). Each NIAS subscale had high AUC for capturing those who fit versus do not fit each ARFID presentation, resulting in proposed cutoffs of ≥10 (sensitivity=.97, specificity=.63), ≥9 (sensitivity=.86, specificity=.70), and ≥ 10 (sensitivity=.68, specificity=.89) on the NIAS-picky eating, NIAS-appetite, and NIAS-fear subscales, respectively. ARFID versus other-ED had high AUC on the NIAS-picky eating (≥10 proposed cutoff), but not NIAS-appetite or NIAS-fear subscales. NIAS subscale cutoffs had a high association with ARFID diagnosis, but only correctly classified other-ED in combination with EDE-Q Global <2.3. To screen for ARFID, we recommend using a screening tool for other-ED (e.g., EDE-Q) in combination with a positive score on any NIAS subscale (i.e., ≥10, ≥9, and/or ≥10 on the NIAS-picky eating, NIAS-appetite, and NIAS-fear subscales, respectively).

Macro- and Micronutrient Intake in Children with Avoidant/Restrictive Food Intake Disorder.

Although case studies in avoidant/restrictive food intake disorder (ARFID) indicate severe nutritional deficiencies in those with a highly limited amount or variety of food intake, systematic analyses on food intake in treatment-seeking children and adolescents with ARFID are lacking. Within this study, n = 20 patients with an interview-based diagnosis of ARFID (0–17 years) were included and compared to n = 20 healthy controls individually matched for age and sex. Children or parents completed three-day food diaries and a food list. Macronutrient, vitamin, and mineral supply was determined based on the percentage of their recommended intake. The results showed a significantly lower total energy and protein intake in ARFID versus controls, with trends for lower fat and carbohydrate intake. ARFID subtypes of limited amount versus variety of food intake significantly differed in macro-, but not micronutrient intake. Those with ARFID met only 20–30% of the recommended intake for most vitamins and minerals, with significantly lower intake relative to controls for vitamin B1, B2, C, K, zinc, iron, and potassium. Variety of food intake was significantly reduced in ARFID versus controls in all food groups except carbohydrates. This study demonstrated that ARFID goes along with reduced everyday life macro- and micronutrient intake, which may increase the risk for developmental and health problems. Future studies additionally assessing serum nutrient levels in a larger sample may further explore differences in food intake across diverse ARFID presentations.

Health professionals' familiarity and experience with providing clinical care for pediatric avoidant/restrictive food intake disorder.

The current study explored the experience and familiarity of pediatric health professionals with avoidant/restrictive food intake disorder (ARFID), and assessed the application of diagnostic criteria in a series of clinical vignettes. Pediatric health professionals were invited to complete an online survey. Data from 93 health professionals from medical and allied health roles who completed the survey were analyzed. Respondents providing care for pediatric feeding/eating disorders were more likely to report familiarity with ARFID than those not typically providing care for feeding/eating disorders. Clinicians who had provided care for pediatric ARFID reported more confidence in clinical management of ARFID than did those who had not yet provided care for ARFID, though there were overall relatively low levels of confidence in providing care for ARFID. Respondents to the clinical vignettes were more likely to confer a diagnosis of ARFID when there were symptoms of both psychosocial impairment and weight loss than when there was psychosocial impairment alone. The results suggest variability in current application of diagnostic criteria for ARFID, low confidence in clinical management of ARFID, and ambiguity in clinicians' judgments regarding whether psychosocial impairment is sufficient to meet a diagnosis of ARFID.
