The high co-occurrence of autism and eating disorders is well established, including for those with Avoidant Restrictive Food Intake Disorder (ARFID). It is therefore important to consider autism and identify possible autism when people present to eating disorder services to ascertain whether further assessment is indicated, to support clinical formulation and to make appropriate adaptations during interventions. This paper explores the utility of a validated autism screening measure, the AQ-10, in a population of children and adolescents who presented to an outpatient eating disorders clinic for an assessment of possible ARFID. Over 19 months, 335 young people were assessed and 246 families with children aged between 4 and 17 years completed one of three versions of the AQ-10 (Child, Adolescent, and Adult), as part of a battery of routinely administered pre-assessment questionnaires. Results indicated that 80.2% (n = 69) of those with an existing autism diagnosis scored above clinical threshold of ≥6 (M = 7.2, SD = 1.9), 43.9% (n = 43) of those queried to be autistic scored above clinical threshold (M = 5.2, SD = 2.5), and 6.5% (n = 4) of non-autistic individuals scored above clinical threshold (M = 2.8, SD = 1.8). Additionally, the AQ-10 satisfactorily discriminated between those with a known autism diagnosis and those who are not autistic across all age groups and sex. We conclude that the AQ-10, alongside a comprehensive clinical assessment and clinical judgment, is a useful screening tool that can support clinicians to identify appropriate onward referrals for autism assessments, aid clinical formulation, and consider appropriate adaptations and reasonable adjustments during ARFID interventions.

Food neophobia (FN) reduces nutritional adequacy and variety which poses a significant concern for children\'s health and well-being We described the FN scores among 8-year-olds and examined its associations with nutrition-related behaviors at 45 months within the Growing Up in New Zealand cohort (n = 4621). FN was estimated using the Food Neophobia Scale (FNS). Mean FNS scores between variable categories were compared using t-tests for independent samples and ANOVA. Associations between FNS scores at 8 years and nutrition-related behaviors at 45-months were examined using multivariate linear regression. The mean (standard deviation) FN score was 46.2 (15.2) with statistically significant differences by sex (boys = 47.6 (15.7), girls = 43.8 (14.2), p=<0.001). For all children, in models adjusted by breastfeeding duration and sociodemographic characteristics: children who sometimes and never/almost never ate the same foods as their parents, scored, on average, 5.8 and 11 points higher in the FNS (versus those who did always/almost always); children who occasionally/never found mealtimes enjoyable scored on average 3.6 points lower in the FNS (versus mostly/quite often); children who always/almost always had the television on during mealtimes scored on average 2.7 higher in the FNS (versus never/almost never). In comparison to children who mostly/quite often had time to talk to others during mealtimes, those who never/occasionally did it scored on average higher points in the FNS overall (1.46 points higher) and within girls (1.73 points higher). These findings support the eating behavior statements in the National Children\'s Food and Nutrition Guidelines, which emphasize early exposure to food variety, limiting mealtime distractions, and acknowledge that parental role modeling shapes children\'s nutrition-related behaviors. Early adoption of preventative interventions for reducing FN in early and middle childhood are needed.

BACKGROUND: Avoidant restrictive food intake disorder (ARFID) is characterized as a pattern of restrictive eating leading to significant medical and/or psychosocial impairment (American Psychiatric Association in Diagnostic and statistical manual of mental disorders, American Psychiatric Association, Washington, D.C., 2013). Most existing research on ARFID utilizes quantitative methodologies to study children and adolescents. As a result, the experiences of adults with ARFID have been underrepresented in research. To fill this gap, the current study examines the lived experiences of adults with a DSM-5 diagnosis of ARFID.
METHODS: Participants (n = 9) included adult women aged 20-42 (M = 27, SD = 6.2) recruited from social media advertising. Open-ended, semi-structured interviews were conducted. Data were analyzed using interpretative phenomenological analysis (IPA).
RESULTS: One of three overarching themes identified by IPA will be discussed in this study: \"A tradeoff between safety and freedom,\" which consists of two subthemes: (a) Ensuring safety from food unknowns and (c) Longing for Freedom. This overarching theme explores the influence of ARFID on an individual\'s sense of safety and freedom.
CONCLUSIONS: This study is one of few to qualitatively examine ARFID, and the only to do so using IPA. Findings offer novel insights relevant to researchers and clinicians who treat adults with ARFID and who wish to increase consideration and understanding of patient lived experience in their work.

BACKGROUND: Avoidant restrictive food intake disorder (ARFID) is a feeding and eating disorder with known acute and longstanding physical health complications in children and young people (CYP) and commonly presents to paediatricians.
OBJECTIVE: To systematically review the published literature on physical health complications in CYP with ARFID using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.
METHODS: A systematic search of PubMed, Embase, Web of Science, PsycINFO and Cochrane Library was performed on 14 February 2024. Studies reporting physical health complications in CYP ≤25 years with ARFID were included. We pooled studies for meta-analysis comparing ARFID with healthy controls or anorexia nervosa (AN).
RESULTS: Of 9058 studies found in searches, we included 132 studies. We found evidence for low weight, nutritional deficiencies and low bone mineral density. CYP with ARFID can present across the weight spectrum; however, the majority of CYP with ARFID were within the healthy weight to underweight range. Most studies reported normal range heart rates and blood pressures in ARFID, but some CYP with ARFID do experience bradycardia and hypotension. CYP with ARFID had higher heart rates than AN (weighted mean difference: 12.93 bpm; 95% CI: 8.65 to 17.21; n=685); heterogeneity was high (I2: 81.33%).
CONCLUSIONS: There is a broad range of physical health complications associated with ARFID requiring clinical consideration. Many CYP with ARFID are not underweight yet still have complications. Less cardiovascular complications found in ARFID compared with AN may be related to chronicity.

BACKGROUND: Picky eating (PE) is common in early childhood, peaking between ages 1 and 5 years. However, PE may persist beyond this normative period and pose threats to health and psychosocial functioning. Avoidant/restrictive food intake disorder (ARFID) involves restrictive eating driven by appetite, preference/selectivity, and/or fear of eating, leading to significant medical and/or psychosocial impairment. This retrospective study examined the relation between early childhood PE onset/duration and ARFID eating restrictions and symptoms.
METHODS: Parents of children ages 6-17 (N = 437) completed a survey about their child\'s eating behavior, including the Nine-item ARFID Screen (NIAS) and questions about PE onset and impacts. Children were then categorized into groups based on PE onset (before or after age 5) and duration: never picky, normative picky, persistent picky, and late-onset picky.
RESULTS: The groups differed (all p < .05) in mean NIAS subscales (picky eating, NIAS-PE; appetite, NIAS-A; fear, NIAS-F) and total scores (NIAS-T). Tukey post-hoc tests found that persistent PEs had significantly higher NIAS-PE, NIAS-A, and NIAS-T scores than never or normative PEs (all p < .05). Chi-Square tests found that persistent PEs were significantly more likely than all other groups to endorse ARFID criteria.
CONCLUSIONS: Findings from this study suggest that PE that persists beyond or is identified after the normative period is associated with elevated ARFID symptoms compared to normative and never PEs. Persistent PE increases risk of impairment from PE and other ARFID eating restrictions. Given the health and psychosocial risks associated with ARFID, early identification and intervention for this group is warranted.

Disruptions in appetite-regulating hormones may contribute to the development and/or maintenance of avoidant/restrictive food intake disorder (ARFID). No study has previously assessed fasting levels of orexigenic ghrelin or anorexigenic peptide YY (PYY), nor their trajectory in response to food intake among youth with ARFID across the weight spectrum. We measured fasting and postprandial (30, 60, 120 minutes post-meal) levels of ghrelin and PYY among 127 males and females with full and subthreshold ARFID (n = 95) and healthy controls (HC; n = 32). We used latent growth curve analyses to examine differences in the trajectories of ghrelin and PYY between ARFID and HC. Fasting levels of ghrelin did not differ in ARFID compared to HC. Among ARFID, ghrelin levels declined more gradually than among HC in the first hour post meal (p =.005), but continued to decline between 60 and 120 minutes post meal, whereas HC plateaued (p =.005). Fasting and PYY trajectory did not differ by group. Findings did not change after adjusting for BMI percentile (M(SD)ARFID = 37(35); M(SD)HC = 53(26); p =.006) or calories consumed during the test meal (M(SD)ARFID = 294(118); M(SD)HC = 384 (48); p <.001). These data highlight a distinct trajectory of ghrelin following a test meal in youth with ARFID. Future research should examine ghrelin dysfunction as an etiological or maintenance factor of ARFID.

Avoidant restrictive food intake disorder (ARFID) is an eating disorder characterized by persistent insufficient nutritional and/or energy intake. ARFID, before referred to as \"selective eating disorder\", was introduced recently in the DSM-5 as a replacement for and expansion of the previous diagnosis. Individuals with ARFID may limit food variety and intake due to avoidance based on the sensory characteristics of the food or related to any adverse consequences of eating without the intention of losing weight and concerns of body image. The limited understanding of avoidant and restrictive eating poses challenges to effective treatment and management, impacting directly on the growth and development of children and adolescents. The ARFID neurobiological concept has not yet been clearly defined to clinical practice for nutritionists, thereby hindering screening and impeding the development of treatment recommendations. This narrative review provide useful practical information to consult the pathophysiology, the neurobiology, the clinical features, the assessment and the treatment for healthcare professionals seeking to enhance their clinical knowledge and management of this disorder.
Avoidant restrictive food intake disorder (ARFID) is an eating disorder characterized by persistent insufficient nutritional and/or energy intake. Individuals with ARFID exhibit limited food intake and variety, often due to a lack in eating, without the primary goal of weight loss. The limited understanding of avoidant and restrictive eating poses challenges in terms of effective treatment and management, which directly impacts the growth and development of children and adolescents, as well as their nutrition and psychosocial well-being. ARFID is a relatively recent diagnostic classification, representing a burgeoning field of study. The identification of diagnostic criteria and the pursuit of new knowledge in this area have only recently begun. Consequently, assessment tools and treatment strategies are still in the process of development and validation. This narrative review explored the neurobiological perspective of ARFID using the three-dimensional model, examined its etiology and risk factors, evaluated clinical screening and evaluation tools, discussed common clinical complications, and presented different types of nutritional, behavioural, and pharmacological interventions used in ARFID treatment.

Infants and children with intestinal failure are at risk for pediatric feeding disorders, which challenge their oral feeding development. This article explores these challenges and offers several practical strategies that can be used by multidisciplinary care teams and at-home caregivers to help support the development of oral feeding in these children and eventually lead to their attaining enteral autonomy.
