Development and Validation of an Inventory to Assess Mealtime Behavior Problems in Children with Autism

Conference proceedings: Inaugural meeting of the consortium for autism, genetic neurodevelopmental disorders, and digestive diseases

OBJECTIVES

Individuals with neurodevelopmental disorders (NDDs), including autism spectrum disorder (ASD), often experience a higher prevalence of gastrointestinal (GI) symptoms but have complex medical and behavioral comorbidities that make diagnosis and treatment difficult. A multi-stakeholder conference was convened to (a) determine patient and family experiences related to GI symptoms in NDDs, (b) review the clinicians' and researchers' perspectives, and (c) determine actionable steps for future research.

METHODS

The Consortium for Autism, Neurodevelopmental Disorders and Digestive Diseases (CANDID; www.candidgi.com) virtually over 2 days in 2022 and consisted of four key activities: (1) an electronic family survey to assess underlying NDDs and GI symptoms, (2) a session focused on family perspectives, (3) review current clinical care and research, and (4) discussion to identify key next steps. Survey results were obtained electronically via the REDCap platform, and descriptive statistics were generated. The sessions were recorded, and themes were identified.

RESULTS

The pre-conference survey ran for ~2 months and 739 families provided responses, with 634 completing all items. 83% had a child with an NDD under age 18, and most patients were White (85%) and non-Hispanic (87%). Constipation (80%), GI reflux disease (51%), and bloating (49%) were the most frequently reported symptoms. Families gave unstructured feedback that the measures used in the surveys were often difficult to answer for patients with NDDs or who were nonspeaking. Family and clinical/scientific sessions identified several common themes, including (1) the need for less invasive diagnostic modalities, (2) the need to validate or adapt existing diagnostic measures (e.g., the Rome IV criteria) and outcome assessments, and (3) the need for enhanced attention to parent and caregiver input in treatment plans.

CONCLUSIONS

Those providing care to children with NDDs, especially those with communication and cognitive challenges, should be aware of the differing needs in this community and consider family perspectives in managing, treating, and measuring GI issues. Future research should focus on adapting or creating diagnostic and research measures for those with NDDs, developing new diagnostic methods to account for diversity in neurodevelopment and communication, and improving methods for family and caregiver engagement in the care of GI disorders.

Recruitment feasibility and dietary and behavioral patterns in toddlers with ASD: Preliminary results from the Autism Eats program

BACKGROUND

Problematic mealtime behaviors and inadequate diet quality are pressing concerns for children with autism spectrum disorder (ASD). This study aimed to evaluate recruitment feasibility and baseline outcomes of the Autism Eats program for children under 3 years with ASD.

METHODS

Recruitment feasibility was assessed through reach and participation rates. The Healthy Eating Index (HEI-2015) scores were calculated from 3-day food records. Problematic mealtime behaviors were assessed with the Brief Autism Mealtime Behavior Inventory. Parental feeding practices were assessed using the Child Feeding Questionnaire. Anthropometric measurements of children and parents were taken. Weight-for-length percentiles were calculated based on the CDC growth charts. Descriptive statistics, one-sample t-tests, and Spearman's rho correlations were used for data analysis.

RESULTS

Of the contacted dyads, 74 % agreed to participate. All 51 enrolled dyads completed baseline survey (100 %), and 98 % completed 3-day food records and anthropometric measurements. Significantly higher problematic mealtime behaviors were observed, compared to the reference (e.g., Total score 55.7 vs. 32.5; p < .001). Children with ASD exhibited lower HEI-2015 scores than national data (e.g., Total score 59 vs. 62). A large proportion of the children (29 %) had a weight-for-length ≥ 95th percentile. Several significant associations were found among mealtime behaviors, diet quality, parental feeding practices, and weight status.

CONCLUSION

Recruitment was highly feasible, and the findings suggest that early nutrition intervention may hold promise in addressing problematic mealtime behaviors and promoting healthier dietary habits in young children with ASD.

Measuring eating disorders in Autistic people: a proposal for future research

While diagnostic pathways for identifying Autism in eating disorder (ED) populations have been developed, the field continues to lack validated psychometric tools to measure EDs for use in the Autistic population. Many commonly used measures for EDs potentially lack validity and reliability in the Autistic population limiting theoretical and practical advancements in the field. This paper outlines current conflicts in autism and ED research and how these can be addressed through psychometric methodology. We discuss: (1) the lack of differentiation between ED pathology and Autistic eating behaviours, as well as the limited inclusion of autism-specific mechanisms in existing tools; (2) the subsequent theoretical and practical implications for researchers, clinicians, and Autistic people; and (3) future directions for psychometric research. Scholars are encouraged to employ participatory designs with autistic people before carefully considering which analytical strategies are used in the Autistic population.

Level of support/commitment and behavior during mealtime and dental care negatively impact the dental caries prevalence in autistic individuals: cross-sectional study

OBJECTIVE

To verify whether factors associated with Autism Spectrum Disorder (ASD) would have impact on the dental-caries prevalence.

MATERIALS AND METHODS

All ASD-individuals receiving care in a specialized center with minimum of 4y old were recruited. Demographic, socioeconomic and behavioral characteristics, level of support/commitment (Childhood Autism Rating Scale), mealtime behavior (Brief Autism Mealtime Behavior Inventory) and medication use were answered by ASD-individual's parents. Behavior during dental care was evaluated from Frankl scale. Dental-caries prevalence was the primary outcome. Three examiners calibrated/trained collected the data. Chi-square test was used to compare the variables impact on the dental-caries prevalence.

RESULTS

61 ASD-individuals were potentially eligible, and the all parents/guardians consent to participate. Dental-caries prevalence was 42.9%, which was statistically associated with lower toothbrushing frequency, higher level of support/commitment, and worse behavior at meals and during in dental care. Dental-caries prevalence was approximately higher twice in ASD-individuals: (i) uncooperative with dental care when compared those cooperative (62% versus 32%, respectively); (ii) with severe level of support when compared to those with mild/moderate level (58% versus 28%, respectively); and (iii) with worse mealtime behavior when compared to those with better behavior (59% versus 28%, respectively). A medium statistical correlation was observed between support level and mealtime behavior (rS=0.39). The BAMBI component statistically associated with dental-caries prevalence was the food refusal (capture problem when a child rejects a presented food, crying, spitting out food).

CONCLUSION

higher required level of support, worse mealtime behavior and uncooperative profile in dental care negatively affect the dental-caries prevalence.

CLINICAL RELEVANCE

our findings provide evidence of the need of specialized, preventive and individualized dental care among ASD-individuals.

Feeding-Related Early Signs of Autism Spectrum Disorder: A Narrative Review

Feeding difficulties are prevalent among individuals with autism spectrum disorder (ASD). Nevertheless, the knowledge about the association between feeding-related early signs and child development remains limited. This review aimed to describe the signs and symptoms related to feeding during child development and to explore their relevance to the diagnosis of ASD. Specialists in nutrition and/or ASD conducted a search of MEDLINE, PsycINFO, and Web of Science databases. Although studies in typically developing children demonstrate age-related variations in hunger and satiety cues, the literature about early feeding indicators in ASD is scarce. Challenges such as shortened breastfeeding duration, difficulties in introducing solid foods, and atypical mealtime behaviors are frequently observed in children with ASD. The eating difficulties experienced during childhood raise concerns for caregivers who base their feeding practices on their perceptions of food acceptance or refusal. Considering the observed associations between feeding difficulties and ASD, the importance of recognizing feeding-related signs according to developmental milestones is emphasized to alert medical professionals that deviation in the formation of feeding habits and skills could indicate the need for ASD diagnostic investigation.

Occupational Therapy Practice Guidelines for Autistic People Across the Lifespan

IMPORTANCE

Occupational therapy practitioners need evidence to support interventions that promote subjective well-being among autistic people and their families through optimal engagement and participation in occupations.

OBJECTIVE

These Practice Guidelines are informed by systematic reviews to expand knowledge of interventions that promote access, inclusion, engagement, and optimal participation in occupations that are meaningful to autistic people. Our intent was to foster occupational therapy practitioners' clinical decision-making and reasoning when working with autistic people and their care partners.

METHOD

These Practice Guidelines were developed on the basis of four systematic reviews, supporting evidence and literature, along with continued revisions and integration through an iterative and collaborative process.

RESULTS

A total of 98 articles were included in the systematic reviews, which are the foundation for practice recommendations in these guidelines. Forty-eight of the systematic review articles were used to inform the clinical recommendations included in these Practice Guidelines.

CONCLUSIONS AND RECOMMENDATIONS

Strong to moderate evidence indicates the need for multidisciplinary, goal-oriented interventions to support autistic people in different contexts. Although there is only emerging evidence in the inclusion of autistic people's strengths, interests, and perspectives to guide occupational therapy interventions, such practices can enhance the delivery of neurodiversity-affirming and trauma-informed practices. In addition, evidence is needed to support participation in activities of daily living (ADLs) for autistic youths. We recommend the use of strengths-based language to describe autistic people and the use of environmental adaptations, care partner education, and coaching to enhance occupational therapy service delivery. Plain-Language Summary: The literature is sparse regarding neurodiversity-affirming and trauma-informed practices for autistic youths, as well as for participation in activities of daily living (ADLs). These Practice Guidelines provide new information on positive mental health development; self-determination; ADLs, instrumental ADLs, play, and leisure occupations for children, adolescents, and adults; person-centered planning for adolescents and adults; and rest and sleep. Information on health management is also provided. Positionality Statement: This article uses the identity-first language autistic people. This nonableist language describes their strengths and abilities and is a conscious decision. This language is favored by autistic communities and self-advocates and has been adopted by health care professionals and researchers (Bottema-Beutel et al., 2021; Kenny et al., 2016). However, we respect the use of person-first language and have made a conscious decision to include research articles that have used this language.

Validation of the Arabic Version of Feeding Handicap Index for Children with Developmental Disabilities (A-FHI-C)

Children with developmental disabilities have different feeding and swallowing problems. The purposes of the present study were to develop an Arabic version of the FHI-C and to evaluate its validity, consistency, and reliability in Arabic children with developmental disabilities for assessing how feeding and swallowing problems impair the physical, functional, and emotional aspects of children's lives. A prospective study including 113 children [62 children with autism spectrum disorder (ASD), 24 with cerebral palsy (CP), 27 with intellectual disability (ID)], in the age range of 2 to 10 years, selected randomly from the swallowing clinic, phoniatrics unit, Otorhinolaryngology department, University hospital between September 2023 and December 2023 complaining of feeding and swallowing problems. Validity was established by comparing patients` scores to typically developed controls (31 children). For test-retest reliability, forty parents filled out the A-FHI-C again two weeks after their initial visit. Cronbach's alpha for A-FHI-C was 0.986, indicating good internal consistency. Intraclass correlation showed 0.850 with a 95% confidence interval from 0.779 to 0.898. All three clinical groups had significantly higher total FHI-C and FHI-C domain scores than the control group, indicating good validation. A-FHI-C was found to have significantly high test-retest reliability. The current study indicates that in children with ASD, CP, ID, feeding problems are more prevalent than children who are typically developed. The scores obtained can be used by phoniatricans to evaluate feeding problems and monitor the progress of the therapy plan in children with developmental disorders.

Parents' perceptions of the impact of the novel coronavirus (COVID-19) on the eating behaviors and routines of children with autism spectrum disorders (ASD)

Background

Restricted interests and repetitive behavior are characteristics of autism spectrum disorder (ASD). The likelihood that persons with ASD will respond adversely to unfamiliar situations is great. The novel coronavirus outbreak has resulted in disruptions to all aspects of routine and behavior. Hence, this study proposed to investigate the impact of the outbreak on the eating behavior and routines of children with ASD in Saudi Arabia through the perceptions of their parents.

Method

A cross-sectional study with a quantitative approach was utilized to obtain data from 150 parents of children with ASD aged ≤18 years in Saudi Arabia. The data collected included demographic data of the parents, the ASD status of the family, impact of COVID-19 to the family, eating behavior of the children with ASD, and daily routines of the children with ASD. Moreover, parents were able to provide comments regarding their children's eating behavior or daily routines.

Results

The study found that changes in the eating behavior of children with ASD were found to differ significantly (p<0.05) based on the number of children with ASD, the age of the children with ASD, the gender of the children with ASD, and the severity of their ASD symptoms. Moreover, changes to dinner-time routines were found to differ significantly (p<0.05) based on the age of the children with ASD. Also, changes to morning routines were found to differ significantly (p<0.05) based on the age of the children with ASD, their gender, and the severity of their ASD symptoms. Additionally, impact of COVID-19 to the family had a significant impact to eating behavior and daily routines of the children with ASD.

Conclusion

This study found that the eating behavior and daily routines of children with ASD in Saudi Arabia have been considerably worsened and changed. The study recommends the collaboration of multidisciplinary teams and parents to modify or design interventions that help to change their eating behavior and routine can be implemented in the home. It also recommends the provision of virtual helplines to aid parents of children with ASD in such cases.

Clinical Correlates and Prevalence of Food Selectivity in Children with Autism Spectrum Disorder

OBJECTIVE

To examine clinical correlates and prevalence of food selectivity (FS) - i.e., self-restricted diet, reluctance to try new foods - in children with autism spectrum disorder (ASD) ascertained from a general outpatient autism clinic.

STUDY DESIGN

A multidisciplinary team (pediatric nurse practitioner, psychologist and dietitian) assessed medical and psychosocial histories and dietary habits in 103 children with ASD (mean age= 5.8 + 2.2 years; range 2-10). Parents rated child mealtime behavior on Brief Autism Mealtime Behavior Inventory (BAMBI) and disruptive behavior on Aberrant Behavior Checklist (ABC). Height and weight measurements were collected. Children were classified as FS or no FS based on parent reported intake and mealtime behavior. A 24-hour dietary recall was used to record intake percentages < 80%. Logistic regression and multivariable modeling were used to evaluate clinical correlates with FS.

RESULTS

Of 103 children, 45.6% (n=47) were classified as FS; 54.4% (n=56) no FS. After adjusting for potential confounders, the odds of FS increased by 1.91 (95% CI: 1.38, 2.64, p<.001) for every half-SD increase in BAMBI total score and by 1.35 (95% CI: 1.05, 1.74, p=.020) for every half-SD increase in ABC Hyperactivity/Noncompliance. No group differences in anthropometrics or nutritional intake were identified.

CONCLUSIONS

FS in children with ASD was strongly associated with greater severity of disruptive mealtime and hyperactivity/noncompliance behaviors. FS was not associated with anthropometrics or nutritional intake.

Dietary intake and gastrointestinal symptoms are altered in children with Autism Spectrum Disorder: the relative contribution of autism-linked traits

BACKGROUND

Dietary and gastrointestinal (GI) problems have been frequently reported in autism spectrum disorder (ASD). However, the relative contributions of autism-linked traits to dietary and GI problems in children with ASD are poorly understood. This study firstly compared the dietary intake and GI symptoms between children with ASD and typically developing children (TDC), and then quantified the relative contributions of autism-linked traits to dietary intake, and relative contributions of autism-linked traits and dietary intake to GI symptoms within the ASD group.

METHODS

A sample of 121 children with ASD and 121 age-matched TDC were eligible for this study. The dietary intake indicators included food groups intakes, food variety, and diet quality. The autism-linked traits included ASD symptom severity, restricted repetitive behaviors (RRBs), sensory profiles, mealtime behaviors, and their subtypes. Linear mixed-effects models and mixed-effects logistic regression models were used to estimate the relative contributions.

RESULTS

Children with ASD had poorer diets with fewer vegetables/fruits, less variety of food, a higher degree of inadequate/unbalanced dietary intake, and more severe constipation/total GI symptoms than age-matched TDC. Within the ASD group, compulsive behavior (a subtype of RRBs) and taste/smell sensitivity were the only traits associated with lower vegetables and fruit consumption, respectively. Self-injurious behavior (a subtype of RRBs) was the only contributing trait to less variety of food. Limited variety (a subtype of mealtime behavior problems) and ASD symptom severity were the primary and secondary contributors to inadequate dietary intake, respectively. ASD symptom severity and limited variety were the primary and secondary contributors to unbalanced dietary intake, respectively. Notably, unbalanced dietary intake was a significant independent factor associated with constipation/total GI symptoms, and autism-linked traits manifested no contributions.

CONCLUSIONS

ASD symptom severity and unbalanced diets were the most important contributors to unbalanced dietary intake and GI symptoms, respectively. Our findings highlight that ASD symptom severity and unbalanced diets could provide the largest benefits for the dietary and GI problems of ASD if they were targeted for early detection and optimal treatment.

The Relationship Between Nutrition-Physical Activity Behaviors of Autistic Children with Their Families and Children's Obesity Levels During Covid Pandemic

The family has a key role in the obesity management of children with autism. This study examines the relationship between the nutrition-physical activity behaviors of autistic children with their families and children's obesity levels during covid-19 pandemic. The descriptive and cross-sectional study involved 80 parents of autistic children. A positive correlation was found between children's mean BMI values before and during the pandemic(p = 0.000). Family Nutrition and Physical Activity Scale(FNPAS) and Brief Autism Mealtime Behavior Inventory(BAMBI) score were 55.18 ± 7.86 and 31.76 ± 8.79, respectively. In addition, it was found that 32.5% of the children ate more than before the pandemic, 50.0% engaged in less physical activity, and 16.3% didn't do any physical activity. The study results suggesting the risk of obesity.

Brief Report: Plasma Leptin and Mealtime Feeding Behaviors Among Children with Autism Spectrum Disorder: A Pilot Study

We examined the relationship between weight status, appetite regulating hormones, and mealtime behaviors among children, (5-12 years old), diagnosed with Autism Spectrum Disorder (ASD) in a cross-sectional study. All (N = 21) completed anthropometry measurements and (n = 18) provided blood samples for hormone analysis. Mealtime behavior, dietary, physical activity, puberty stage, and social impairment data were collected. Under fasting conditions, overweight/obese (OWOB) participants, (n = 6), had higher leptin concentrations (p < 0.02) and more feeding challenges (p < 0.05) than normal weight (n = 15). Higher leptin levels and disruptions in mealtime behaviors may exist among OWOB children in this study. Future longitudinal studies that examine appetite regulating hormones and mealtime behaviors may inform our understanding of the role of these markers in the development of obesity in ASD.

Eating and Sensory Features of Children With Autism Spectrum Disorder and Their Typically Developing Peers

IMPORTANCE

Impaired sensory processing is associated with eating problems. There seem to be no previous studies that compare those who have autism spectrum disorder (ASD) with eating problems (ASD-W) and those with ASD without eating problems (ASD-WO) with typically developing (TD) groups. Comparisons are expected to provide further knowledge to guide the intervention programs.

OBJECTIVE

To investigate differences among ASD-W, ASD-WO, and TD groups in eating and sensory features; to detect associations between sensory and eating behaviors and any most involved sensory dimensions; and to search for age-related differences in sensory and eating features in ASD.

DESIGN

Nonrandomized comparison study.

SETTING

Questionnaires administered as parent interviews.

PARTICIPANTS

A total of 165 children were recruited: 117 with ASD and 48 TD children.

OUTCOMES AND MEASURES

Standardized questionnaires: the Brief Autism Mealtime Behaviors Inventory for eating problems; the Short Sensory Profile and the Sensory Experience Questionnaire for sensory problems.

RESULTS

The ASD-W group showed generalized, impaired eating behaviors and turned out to be the most impaired with regard to sensory responsiveness. No differences in feeding behaviors were found between the ASD-WO and TD groups. All children with ASD showed sensory hyper- or hyporesponsiveness. Four main sensory dimensions were found to be associated with eating behaviors in ASD. No age differences were found in the eating and sensory behaviors of children with ASD.

CONCLUSIONS AND RELEVANCE

Differing eating and sensory profiles were found between the ASD and TD groups, especially in children with ASD-W. Early eating interventions using sensory stimulations are strongly recommended. What This Article Adds: This study reports novel information derived from the comparisons of children with ASD with eating problems and those with ASD without eating problems with typically developing groups of children.

Clinical Validation of Feeding Handicap Index for Children (FHI-C)

Children with developmental disabilities (DD) exhibit feeding and swallowing difficulties, which can have an impact on nutritional, developmental, and psychological aspects. The existing tools assess the nature of feeding problems and behaviors only. The present study aimed to assess the physical, functional, and emotional domains in children with DD with feeding issues using Feeding handicap index for children (FHI-C). For clinical validation, FHI-C was administered on the parents/caregivers of 60 children with cerebral palsy, 61 with autism spectrum disorder, 59 with intellectual disability and 60 typically developing children in the age range of 2 to 10 years. The results revealed that the mean scores (Total FHI-C and FHI-C domain scores) were significantly higher for all three clinical groups than for the control group, which revealed good clinical validity. Also, FHI-C was found to have significantly high test-retest reliability. The study presents a valid and reliable tool for assessing the psychosocial handicapping effects of feeding problems in children with DD. FHI-C provides a holistic picture about the psychosocial impact of feeding problems in children with DD and will assist the clinicians in prioritizing the goals for feeding therapy. The scores obtained can be used as reference for pre and post therapy comparison purposes.

Screening for Caregiver-Reported Feeding Concerns in Children with Autism Spectrum Disorder in a Tertiary-Care Clinic

OBJECTIVE

Feeding concerns, primarily food selectivity, are commonly observed in children with autism spectrum disorder (ASD). Prevalence rates suggest that at least half of autistic youth have feeding difficulties.

METHODS

A retrospective chart review examining records of a large cohort of autistic children (N = 746) referred for ASD evaluation was conducted. Families completed a survey regarding feeding concerns in their children before a diagnostic evaluation.

RESULTS

Post hoc analyses based on retrospective chart review revealed approximately 30% of caregivers reported significant difficulty feeding their child. Young age, food selectivity, and concerns about weight were associated with increased likelihood of reported feeding difficulties. There was clear overlap between overall feeding difficulties and specific food selectivity; however, 1 in 5 children whose caregivers did not report feeding difficulties endorsed food selectivity.

CONCLUSION

Findings highlight the need for multipronged approaches to screening to facilitate service prioritization by pediatric providers.

Food Selectivity in Children with Autism Spectrum Disorder: A Statistical Analysis in Southern Italy

This paper focuses on autism spectrum disorder (ASD) and food selectivity, both of which are prevalent in the pediatric population. In this context, the authors paid attention to food selectivity and its possible correlation with the atypicality of sensory processes, outlining the useful rehabilitation treatments to draw on. This research included the parents or caregivers of pediatric patients diagnosed with autism spectrum disorder and placed within a therapeutic clinic. The sample is composed of 111 children, males and females, aged between 2 and 10 years, and includes 60 children diagnosed with autism and 51 children with normotypical development, similar in characteristics but without the disorder. The standardized questionnaire, "Brief Autism Mealtime Behavior Inventory", was developed to examine behavior during meals, especially in children with ASD. The "Brief Sensory Profile", and the "Child Oral and Motor Proficiency Scale", were also administered. The results obtained from the analysis lead to evidence of eating and food selectivity difficulty. Additionally, our study demonstrates that food selectivity can be caused by extreme sensory modulation and sensory problems related to the smell, texture, color, and temperature of food. In fact, the results obtained emphasize the correlation between food selectivity and the sensory domains of taste and smell. Furthermore, this research highlights a correlation between motor skills and eating skills, particularly regarding food selectivity, which is closely associated with atypical and disruptive behaviors during meals.

A Scoping Review of Tools to Assess Diet in Children and Adolescents with Autism Spectrum Disorder

Eating is considered one of the activities of daily living most affected by autism spectrum disorder (ASD) in children and adolescents and, therefore, needs to be thoroughly assessed using specific tools. The aim of this scoping review was to describe the most widely used tool to assess diet in children and adolescents with ASD. A search was conducted on PubMed, Scopus, EMBASE, Web of Science and PsycINFO databases. Two authors screened the articles and included all randomized or non-randomized studies published in English or Spanish in the last five years in which the diet of children and adolescents with ASD was assessed. Fifteen studies were included in this review. Mealtime behaviour was the most assessed variable in the included studies (n = 7). Thirteen different assessment tools were identified to evaluate the diet of children and adolescents with ASD, mainly at ages 2-12 (n = 11). The Brief Assessment scale for Mealtime Behavior in Children (BAMBI) and 24-h recalls were the most commonly used dietary assessment tools in the included studies. Our results can help professionals in the selection of an optimal scale to assess diet in children and adolescents with ASD.

Association between feeding/mealtime behavior problems and internalizing/externalizing problems in autism spectrum disorder, other neurodevelopmental disorders and typically developing children

BACKGROUND

The aim of current study was to examine the nature and prevalence of feeding problems and mealtime behavior problems in children with autism spectrum disorder (ASD) comparing to children with other neurodevelopmental disorders (NNDs) and TD children. We also investigated the impact of intelligence quotient (IQ) and/or emotional and behavioral problems on feeding and mealtime behavior problems.

METHODS

Participants completed the following tests: Social Communication Questionnaire (SCQ), Child Behavior Checklist (CBCL), Brief Autism Mealtime Behavior Inventory (BAMBI) and Behavioral Pediatric Feeding Assessment Scale (BPFAS).

RESULTS

Children with ASD showed more feeding and mealtime behavior problems including food refusal (P<0.001, P<0.001) and limited variety of foods (P=0.014; P=0.018) compared with NDDs and TD children. ASD group showed more problems in mealtime behavior (P=0.034) and parent behaviors (P=0.028) compared to TD group. Internalizing (P=0.003) and externalizing (P=0.008) problems were positively related to parent frustration during mealtime in ASD group.

CONCLUSIONS

These results suggest that routine screening for feeding and mealtime behavior problems among children with ASD is necessary to prevent dietary inadequacies that may be associated with eating habits.

Gastrointestinal Dysfunction in Genetically Defined Neurodevelopmental Disorders

Gastrointestinal symptoms are common in most forms of neurodevelopment disorders (NDDs) such as in autism spectrum disorders (ASD). The current patient-reported outcome measures with validated questionnaires used in the general population of children without NDDS cannot be used in the autistic individuals. We explore here the multifactorial pathophysiology of ASD and the role of genetics and the environment in this disease spectrum and focus instead on possible diagnostics that could provide future objective insight into the connection of the gut-brain-microbiome in this disease entity. We provide our own data from both humans and a zebrafish model of ASD called Phelan-McDermid Syndrome. We hope that this review highlights the gaps in our current knowledge on many of these profound NDDs and that it provides a future framework upon which clinicians and researchers can build and network with other interested multidisciplinary specialties.

Associations between parenting strategies and BMI percentile among Latino children and youth with intellectual and developmental disabilities

Introduction

Maintaining healthy weight is a challenge for all children, and particularly for children with IDD compared to nondisabled children and for Latino children compared to non-Latino White children. Parenting practices related to food intake and physical activity have been found to be important in maintaining children's weight. In this study, we describe the prevalence of overweight and obesity status among Latino children with IDD and their maternal caregivers and determine the relationship between food and physical activity parenting practices and childhood obesity among Latino children with IDD.

Methods

We interviewed 94 Latino parent/child dyads and collected information about parenting practices, home environment, and parent and child height and weight using standardized measures. Parent body mass index (BMI) and child BMI percentile were calculated from height and weight.

Results

The combined overweight/obesity status for children in our sample was high (60.3%) compared to national rates among nondisabled Latino children (56%) and non-Latino White children with autism (37%). Contrary to research on nondisabled children, we found that greater parental use of controlling dietary strategies was associated with lower BMI percentile in Latino children with IDD. These findings may be indicative of the fact that children with IDD tend to have unique dietary behaviors that warrant more disability and culturally sensitive strategies.

Discussion

Our findings suggest that overweight and obesity is especially prevalent for Latino children with IDD and that more research is needed on family factors that promote health in Latino families of children with IDD.

The Efficacy of the Global Intensive Feeding Therapy on Feeding and Swallowing Abilities in Children with Autism Spectrum Disorder: A Pilot Study

The present investigation aims to explore the efficacy of Global Intensive Feeding Therapy (GIFT) on feeding and swallowing abilities in children with autism spectrum disorder (ASD). GIFT was developed as an intensive rehabilitation approach, divided into 30 sessions for 2 weeks, three times a day. GIFT focused on (a) encouraging desensitization; (b) widening the food repertoire (in terms of both variety and quantity); (c) reducing inappropriate mealtime behaviors; and (d) encouraging the development of appropriate chewing and swallowing abilities. GIFT was preliminarily implemented among 11 children with a diagnosis of ASD. To measure the efficacy of GIFT, the Karaduman Chewing Performance Scale (KCPS), the Brief Autism Mealtime Behavior Inventory (BAMBI), and food repertoire were investigated using Wilcoxon signed-rank test in three different times: baseline (T1), after treatment (T2), and one month after treatment (T3). Using Bonferroni correction, statistically significant differences were found between T1 and T2 for behavioral issues, as measured with BAMBI (p = 0.007), as well as for chewing abilities as measured with KCPS (p = 0.005) and for food acceptance (p = 0.005). These improvements were maintained after a month of follow-up, thanks to the collaboration of families and/or primary caregivers. In conclusion, GIFT seems to be an effective approach to improving behavioral issues, food acceptance, and chewing abilities in children with ASD.

Brief Autism Mealtime Behavior Inventory (BAMBI): Italian Translation and Validation

Food selectivity is among the most common problems for children with Autism Spectrum Disorder (ASD). The present study aims to validate the Brief Autism Mealtime Behavior Inventory (BAMBI) in an Italian population of children with ASD. BAMBI was translated and cross-culturally adapted following international guidelines, then we investigated internal consistency as measured by Cronbach's alpha and test-retest reliability, as measured by the Intraclass Correlation Coefficient (ICC) in a sample of both children with ASD and with typical development (TD). A total of 131 children were recruited in a clinical and community sample. Internal consistency revealed significant data for both TD and ASD children, with a Cronbach's Alpha of 0.86 and 0.71, respectively. Test-retest reliability showed excellent values for each item of the BAMBI (range 0.83-1.00). Furthermore, we investigated differences in gender and body max index; however, no significant differences were found among groups. In conclusion, the Italian version of the BAMBI showed good internal consistency and test-retest reliability and it can be used for clinical and research purposes.

Food Selectivity in Children with Autism: Guidelines for Assessment and Clinical Interventions

Autisms Spectrum Disorders (ASD) are characterized by core symptoms (social communication and restricted and repetitive behaviors) and related comorbidities, including sensory anomalies, feeding issues, and challenging behaviors. Children with ASD experience significantly more feeding problems than their peers. In fact, parents and clinicians have to manage daily the burden of various dysfunctional behaviors of children at mealtimes (food refusal, limited variety of food, single food intake, or liquid diet). These dysfunctional behaviors at mealtime depend on different factors that are either medical/sensorial or behavioral. Consequently, a correct assessment is necessary in order to program an effective clinical intervention. The aim of this study is to provide clinicians with a guideline regarding food selectivity concerning possible explanations of the phenomenon, along with a direct/indirect assessment gathering detailed and useful information about target feeding behaviors. Finally, a description of evidence-based sensorial and behavioral strategies useful also for parent-mediated intervention is reported addressing food selectivity in children with ASD.

Evaluation and Management of Pediatric Feeding Disorder

Feeding disorders are increasingly common in children, especially as medical advancements improve the life expectancy of children born with prematurity and complex medical conditions. The most common symptoms include malnutrition, refusal to eat and drink, food pocketing, disruptive feeding behavior, slow feeding, food selectivity or rigid food preferences, limited appetite, and delayed feeding milestones. A unifying diagnostic definition of pediatric feeding disorder has been proposed by a panel of experts to improve the quality of health care and advance research. Referral to specialized care should be considered when feeding problems are complex or difficult to resolve. In this review, we provide an overview of the evaluation and management of pediatric feeding disorders and information that may be useful when considering whether referral to specialized care may be beneficial.

Gastrointestinal Disorders and Food Selectivity: Relationship with Sleep and Challenging Behavior in Children with Autism Spectrum Disorder

The aim of this study was to evaluate the interaction between gastrointestinal (GI) disorders, sleep problems, and challenging behaviors in children with a diagnosis of Autism Spectrum Disorder (ASD) and their effect on parental stress. The secondary objective was to assess the frequency and type of GI and feeding disorders in a sample of children with ASD through a multidisciplinary assessment and, finally, to investigate families' perceptions and satisfaction with the proposed multidisciplinary approach. All children underwent a comprehensive gastroenterological and neuropsychiatric evaluation supported by standardized questionnaires. Pediatric gastroenterologists, specifically trained in Applied Behavior Analysis (ABA), provided advice for parent-delivered behavioral intervention for food selectivity. Thirty-six children with an autism diagnosis (29 males, age 4.5 +/-2.2 years, mean +/- SD) were enrolled. A positive correlation between sleep problems and aggressive behavior was found, and this association was stronger in children experiencing more problematic mealtime behaviors (b = 0.788, p = 0.014). Sleep difficulties were associated with stereotyped behaviors and parent-perceived stress. Parents interviewed about the gastroenterology visit perceived this multidisciplinary approach as helpful in addressing food selectivity. This study shows that sleep and mealtime issues can have a synergistic negative impact on ASD symptoms. A multidisciplinary approach and an integrated assessment of GI, feeding problems, and sleep disorders could be helpful in diagnosing comorbidities and to provide targeted advice to parents.

Exploration of Treatment Response in Parent Training for Children with Autism Spectrum Disorder and Moderate Food Selectivity

Managing Eating Aversions and Limited Variety (MEAL) Plan is a structured parent-mediated intervention for children with autism spectrum disorder and moderate food selectivity. Our previously reported group-based clinical trial revealed a positive treatment response rate of 47.3%. Although encouraging, this response rate raises questions about factors that may affect treatment outcomes. Here, we examine the impact of child and parent characteristics and feeding behaviors on treatment response. Higher maternal education and higher child communication abilities at baseline were associated with positive treatment response. Improvement in sitting at the table and reductions in disruptive mealtime behavior promoted treatment success. Results also suggest that individually delivered MEAL Plan may offer more flexibility than group-based intervention for some parents.

Treatment of Feeding Concerns in Children With Autism Spectrum Disorder: A Systematic Review of Behavioral Interventions With Caregiver Training

Successful feeding intervention ultimately requires generalization and adoption of treatment into the home. Treatment models, however, differ regarding how and when caregivers are integrated into care delivery process. Some treatments involve a primary model of parent training with caregivers serving as co-therapist at the onset of intervention, while others involve a complimentary model where a therapist delivers the intervention and caregiver training occurs once the child’s behavior is stable. This review systematically evaluates the evidence-base regarding behavioral feeding intervention for children with autism spectrum disorder (ASD), with a specific focus on interventions involving parent training. Results provide further evidence regarding the potential benefits of behavioral intervention to improve feeding concerns in ASD, while also highlighting growing attention to documenting and/or evaluating parent training within the treatment literature. Important questions remain regarding factors guiding the use of a primary or complimentary model of parent training.

Dietary intake in children on the autism spectrum is altered and linked to differences in autistic traits and sensory processing styles

Diets of children and adolescents on the autism spectrum often differ when compared to their non-autistic peers. Most dietary studies have been limited by small sample sizes and rarely assess the heterogeneity of autism. Addressing this gap, this study compared the anthropometrics, dietary composition, dietary quality, and food variety of 154 Australian children and adolescents on the spectrum and 213 non-autistic children (71 siblings and 142 unrelated controls). Beyond the case-control approach, within-group comparisons assessed the influence of autism clinical presentations and sensory processing styles on body mass index (BMI) and measures of dietary intake among those on the spectrum. In this word first study of diet that included between-group comparisons with non-autistic peers (siblings and an unrelated comparison group) and within-autism group comparisons, we found that children on the spectrum consumed limited variety and lower quality of food and non-autistic siblings also ate comparably higher levels of energy-dense, nutrient poor food, and less diary. This may be due to autistic traits influencing family's diets or shared sensory sensitivities driving dietary intake. Within the autism group, higher autistic traits were associated with lower BMIs and a specific dietary pattern higher in simple carbohydrates and lower in unprocessed protein. Contrastingly, greater sensitivity to sensory stimuli was associated with a healthier diet. Increased age was linked to more varied diets but also diets higher in saturated fats and energy-dense, nutrient poor foods. Overall, this research highlights that potential mediators of dietary intake, such as familial influences, autistic traits, sensory processing styles, age and sex, need to be considered when assessing diet in the autistic population. LAY SUMMARY: In this study of dietary differences linked to autism, children, and teenagers on the spectrum ate fewer different foods and were less likely to eat recommended amounts of fruits and vegetables when compared to non-autistic siblings and unrelated children and teenagers. There were also family differences, in that those on the spectrum and their siblings ate more unhealthy foods and less dairy. Among those on the spectrum, dietary differences were linked to age, sex, autistic traits and sensory processing styles.

A nutrition education intervention to improve eating behaviors of children with autism spectrum disorder: Study protocol for a pilot randomized controlled trial

Autism spectrum disorder (ASD) is a developmental disorder that affects communication and social behaviors. Children with ASD often experience mealtime behavior challenges and selective eating behaviors. They also tend to consume fewer fruits and vegetables and more high-energy dense foods, compared to neurotypical peers. A nutrition intervention was designed to prevent the development of feeding disorders and the long-term negative health impacts associated with poor dietary intake. This randomized controlled trial will evaluate the feasibility and preliminary efficacy of the nutrition education intervention for children with ASD and their parents through the Early Intervention (EI) services. We will recruit EI providers and parent-child dyads (n = 48) from EI programs, and randomly assign them into Autism Eats intervention (n = 24) or enhance usual care (EUC) comparison group (n = 24). The Autism Eats is 10 weekly sessions delivered individually as part of EI, while the EUC group will receive only 1 nutrition education session and then weekly parent handouts. The Autism Eats integrates ASD-specific feeding strategies and behaviorally-focused intervention strategies such as goal setting. Feasibility indicators include reach/participation, attrition, completion, fidelity, compatibility, and qualitative participant feedback. Outcome measures include dietary intakes and mealtime behaviors of children with ASD using 3-day food records and a validated questionnaire, the Brief Autism Mealtime Behavior Inventory (BAMBI). We will examine whether there are differences in children's food intakes, variety, diet quality, and mealtime behaviors between Autism Eats and EUC groups at post-intervention and 5-month follow-up assessment. This study will provide critical data to inform a full-scale randomized controlled trial.

Weight Status and Associated Risk Factors of Mealtime Behaviours among Children with Autism Spectrum Disorder

Atypical mealtime behaviours in children with autism spectrum disorder (ASD) have been linked with oral sensory hypersensitivity that may contribute to food selectivity and weight issues. This cross-sectional study aims to determine the association between atypical mealtime behaviours and associated risk factors besides exploring the prevalence of overweight and obesity among Malaysian children with ASD in community settings. A total of 150 children with ASD aged 3−11 years participated in this study. A self-administered questionnaire on sociodemographic variables, mealtime behaviours and oral sensory processing was completed by the caregivers. The prevalence of overweight in the study samples was 18.5%, whereas obesity was 20.0%. In a multivariate analysis model, oral sensory processing (B = 0.608, 95% CI = 0.493, 0.722, p < 0.001), severity of autism symptoms (moderate and severe) (B = 2.585, 95% CI = 0.722, 4.448, p = 0.007) and younger children with ASD (B = −0.694, 95% CI = −1.189, −0.199, p = 0.006) were found as independent predictors of atypical mealtime behaviours. Children with ASD aged 3−11 years old have a higher prevalence of being overweight and obese, thus requiring regular anthropometric screening in community settings by relevant healthcare professionals. Furthermore, a relationship was found between oral sensory difficulties and atypical mealtime behaviours in children with ASD. A multidisciplinary approach is crucial in the overall management of food selectivity in this population.

Characteristics of the autism spectrum disorder gastrointestinal and related behaviors inventory in children

Gastrointestinal (GI) symptoms are one of the prevalent co-occurring issues in autism spectrum disorder (ASD), though the range of symptom frequency estimates varies dramatically across studies, which can limit the further research of GI issues in ASD as well as potential treatment strategies. The wide range of prevalence estimates is partly due to the lack of standardized, validated measures of GI symptoms among people with ASD. The goal of this study was to (1) develop a measure, which included non-verbal and mealtime behaviors, to assess for GI symptoms and (2) evaluate its psychometric characteristics. This was accomplished by drawing on two existing tools, Autism Treatment Network Gastrointestinal Inventory and the Brief Autism Mealtime Behavior Inventory, and deriving new items, to create the "ASD Gastrointestinal and Related Behaviors Inventory" (ASD-GIRBI). The ASD-GIRBI was piloted in an online registry of families with a child with ASD. A psychometric analysis was carried out in a sample of 334 children aged 6-17 years with ASD, resulting in a 36-item tool. The Cronbach's alpha for the overall scale was 0.88. Exploratory factor analysis identified a seven-factor model (1. Bowel movement pain; 2. Aggressive or disruptive during mealtimes; 3. Particular with foods; 4. Abdominal pain and upset stomach; 5. Refusing food; 6. Constipation and encopresis; 7. Motor or other behaviors). Following validation in an independent sample with clinical evaluation of GI symptoms, this tool will be helpful for both research and clinical purposes.

A Preliminary Evaluation of a Brief Behavioral Parent Training for Challenging Behavior in Autism Spectrum Disorder

Children with autism spectrum disorder (ASD) often exhibit challenging behaviors. Existing behavioral parent trainings (BPT) address ASD symptomology, but are lengthy and associated with significant attrition. In the current pilot study, a longitudinal randomized controlled trial was used to evaluate a novel brief BPT targeting caregivers of children with ASD ages 5–9. The 6-session BPT, delivered in a group format, focused on high-frequency challenging behaviors (e.g., problem behaviors, feeding and sleep issues). Caregivers who received BPT (n = 29), relative to an active control (psychoeducation/supportive therapy; n = 9), reported higher treatment satisfaction and acceptability. Challenging behaviors were reduced in the BPT and active control groups. The novel BPT was a feasible and acceptable intervention to target challenging behaviors in youth with ASD.

Convergent validity of the Autism Spectrum Disorder Mealtime Behavior Questionnaire (ASD-MBQ) for children with autism spectrum disorder

There was a growing interest in difficulties with eating as one of the most problematic symptoms in children with autism spectrum disorder (ASD). The purpose of this study is to examine the convergent validity of the Autism Spectrum Disorder Mealtime Behavior Questionnaire (ASD-MBQ) with the Asahide’s test for social adjustment skills, the Japanese version of the short version of the sensory profile questionnaire, the Japanese version of the Social Communication Questionnaire, and the Parenting Strain Index in Japanese children with ASD. The final sample contained 294 children who were diagnosed as the ASD based on the DSM-5 criteria, the mean age of children was 10 ± 4 years (range: 3–18 years). The ASD-MBQ is a questionnaire that comprised of 42 items that are classified into five subdomains: selective eating, clumsiness/manners, interest in/concentration on eating, oral-motor function, and overeating. Spearman’s rank correlation coefficient revealed that the ASD-MBQ showed the moderate to high correlation coefficient with all four external criteria. Our results in this study supported the sufficient convergent validity in the ASD-MBQ. Therefore, the ASD-MBQ could be a useful tool for research and practice in a wide range of children with ASD aged 3 to 18.

Dealing with food selectivity and mealtime behaviour in school-children with autism: a qualitative study of special education teachers in Japan

Food selectivity in children with autism spectrum disorder (ASD) is a serious issue in special needs schools, and special education teachers face various difficulties in their management of the problem. The aim of this study is to investigate the difficulties that special education teachers face in managing food selectivity in children with ASD. Data were obtained from 12 special education teachers in 2018 via semi-structured in-depth interviews. Thematic analysis was used to identify key conceptions of the participants' experiences, while qualitative analysis of the interview data revealed three major themes. Their personal and professional thoughts and hopes regarding eating habits in children, feelings of uncertainty about their practice, and their interactions with the children and their parents were the key factors behind the difficulties they experience as special education teachers. The findings improve our understanding of the challenges experienced by teachers managing food selectivity in children with ASD. A different conceptualisation of the problem may lead to difficulties in collaboration among the people who are tasked with solving the problem.

Mealtime Support: A Pilot Case Series study of an Effective, Cost-saving Outpatient Hunger-Based Feeding Program for Tube Dependency

Tube feeding is essential for children who cannot meet nutritional requirements orally. Over time, this can lead to tube dependency with negative impacts on the quality of life of children and families.

Objective

We aimed to examine the efficacy of a multidisciplinary child-led, hunger-based approach called "Mealtime Support" at the Stollery Children's Hospital in Edmonton. Nutritional outcomes, parental satisfaction, and cost implications were evaluated over 9 months postprogram completion per child.

Methods

The ambulatory meal program was delivered 2-3 times a day, for 2 weeks, by an occupational therapist and dietitian, under medical supervision. Hunger was promoted by reducing tube fed calories by 80% before commencement. Caregivers completed 12-question subjective surveys pre- and postintervention. Microcosting methods compared costs between the program and ongoing tube feeding.

Results

From 2016 to 2017, 6 children were enrolled and 5 completed the program. At 1-month postintervention, 4/5 of the children were 100% orally fed. Parents reported improvement in mealtime struggles (P = 0.005), reduction in worry about their child's eating (P = 0.005), and improvement in their child's appetite/variety foods eaten (P = 0.004). Over 2 years, the potential cost savings were estimated at $43,471.00. By 6 months, all feeding tubes were removed.

Conclusions

Mealtime support was safe and successful in reducing tube dependency and cost-effective compared to no intervention or hospital based programs, which suggests that there is a need to develop and fund Canadian outpatient feeding programs.

Feeding difficulties in Asian children with autism spectrum disorder

BACKGROUND

To characterize the nature and severity of feeding difficulties in Asian young children with Autism Spectrum Disorders (ASD) and identify potential predictors of poorer feeding outcomes.

METHODS

Cross sectional study of children aged 1-7 years with ASD. Parents completed the following: demographic information, brief autism mealtime behavior inventory, aberrant behavior checklist (ABC), behavioral pediatrics feeding assessment scale (BPFAS) and caregiver feeding style questionnaire. Additional information (medical data, cognitive and developmental assessment results, e.g., Autism Diagnostic Observation Schedule Second Edition, Autism Diagnostic Interview, Revised, Vineland Adaptive Behaviour Scales, etc.) were subsequently obtained from electronic medical records retrospectively by one of the study team members.

RESULTS

Of the 67 children, 28.4% had feeding difficulties (high BPFAS total frequency score). Caregiver feeding styles were authoritarian (34.8%) or indulgent (39.4%). Child characteristics did not significantly predict for the severity of feeding difficulties. Univariate analysis revealed that authoritarian feeding style (p = 0.001) and ABC hyperactivity score (p = 0.006) were significantly associated with BPFAS severity score. Multivariate analysis revealed that ABC hyperactivity score remained significantly associated with BPFAS severity score after controlling for all other ABC subscale scores. A final regression model including all child characteristics and ABC scores did not reveal any significant predictors of BPFAS total frequency score (R2 = 0.557).

CONCLUSION

Our findings suggest an association between hyperactivity, authoritarian feeding style and feeding difficulties. Children with ASD who have significant hyperactivity behaviors in the context of parents with an authoritarian feeding style should be actively screened for problematic feeding behaviors.

Mapping the gaps: A scoping review of research on pediatric feeding disorder

BACKGROUND & AIMS

Pediatric feeding disorder (PFD) is defined as impaired oral intake that is not age-appropriate, and is associated with medical, nutritional, feeding skill, and/or psychosocial dysfunction. As PFD is prevalent and increasing, so are publications on the topic; however, the research literature is often disparate in terminology used and siloed by discipline. Greater understanding of the current research concerning PFD will help identify areas in need of further study. The purpose of this scoping review is to examine the extent, range, and nature of research activities concerning PFD and to identify gaps in the empirical literature.

METHODS

Three electronic databases (PubMed/Medline, CINAHL, PsycINFO) were searched using terms related to pediatric feeding disorder, which include, but not limited to, "feeding disorder/problem/difficulty", "avoidant restrictive food intake disorder (ARFID)", "dysphagia", "selective/picky eating", "problematic mealtime behaviors" or "food refusal". The following limits were placed on the search: full text, humans, English, and age limit (up to 18 years old), and publication date (last 10 years). Covidence software was used to facilitate a systematic data management/analysis. Two people in the research team independently reviewed each result (screening titles and abstracts first, then moving to the full texts) to identify studies that met our inclusion/exclusion criteria and conflicts were resolved through a team discussion. Data were charted regarding disciplines of the authors, study purposes, study settings/locations, study methodologies, and study participants. Descriptive statistics and thematic analyses were used to summarize the characteristics of the studies.

RESULTS

The initial search resulted in 5354 articles after removing duplicates between the databases. With a final set of articles (n = 415), data charting was completed. The majority of studies were completed by authors from Psychology (n = 171) and Medicine (n = 123). The most studied aims were to examine attributes of feeding problems (n = 168) and/or factors associated with feeding problems (n = 183). Sample size median was 53. A total of 166 of the 415 studies examined the effect of an intervention, treatment, or program, but dose of the intervention was difficult or impossible to report across studies. Feeding was studied as an outcome in 400 out of the 415 studies. A closer accounting of the systematically developed parent-report tools revealed 50 distinct parent report tools used across the subset of studies utilizing parent report outcomes (n = 123).

CONCLUSIONS

The results of this scoping review highlight the designs and methods used in research on PFD. This reveals critical gaps in knowledge generation and barriers to intervention replication.

Parent-reported feeding characteristics in children with ASD vs. children who are typically developing

Background

Parents of children with autism spectrum disorders (ASDs) often report that their children have multiple dietary behavior problems than parents of typically developing (TD) children do. This may affect proper nutrition and subsequently adequate growth and development in children with ASD. The current study aimed to assess the feeding behavior in recently diagnosed children with autism spectrum disorders (ASD) ranged in age from 2 to 4 years and compare it with typically developing (TD) children and to explore the relationship between feeding behaviors and autism severity using the Montreal Children’s Hospital Feeding Scale (MCH) and Childhood Autism Rating Scale (CARS), respectively. Parents of 35 preschool children (2–4 years) with ASD completed reports of physical measurements, feeding interview, Childhood Autism Rating Scale (CARS), and Montreal Children’s Hospital Feeding Scale (MCH Feeding-Scale). The collected data from parents of children with ASD were analyzed and compared with 70 typically developed children matched with age and sex.

Results

ASD children showed statistically significantly more problematic feeding behaviors in most of the assessed eating characters compared with TD children, e.g., food neophobia, eating non-food items instead of food, requiring assistance during eating, and feeding avoidance to particular textures and taste. The mean total score of the MCH feeding scale differed significantly between children with ASD and TD children. No correlation was found between the mean total score of the MCH feeding scale and CARS scores.

Conclusion

Our findings revealed a high rate of behavioral feeding problems in children with ASD. Future work will be needed to follow up the feeding behaviors and to develop practical feeding approaches for ASD children to maintain nutritional adequacy.

An investigation of the relationship between the eating behaviours of children with typical development and autism spectrum disorders and parent attitudes during mealtime eating behaviours and parent attitudes during mealtime

BACKGROUND

Nutrition has significant importance in the course of growth and development in early childhood. Selective and fussy eating is prevalent among children with autism spectrum disorder and can have a profound impact on parents' mealtime actions.

AIMS

The study aimed to investigate the relationship between parental mealtime actions and the eating behaviours of children aged 3-5 years with typical development (TD) and autism spectrum disorder (ASD).

METHODS

A total of 180 parents of children between 3 and 5 years in Ankara participated in the study; 90 were parents of children with TD, and 90 were parents of children with ASD. We measured the variables using the Brief Assessment of Mealtime Behaviour in Children (BAMBIC), Children's Eating Behaviour Questionnaire (CEBQ), and Parent Mealtime Action Scale (PMAS).

RESULTS

The results revealed that food refusal, disruptive behaviours, and limited variety in TD children were related to parental actions, such as the use of rewards. We also found a negative correlation between enjoyment of food and the use of rewards. Children with ASD displayed differences concerning food refusal, and their parents were found to prepare more special meals for them compared with children with TD.

CONCLUSION

Despite differences, the eating behaviours of children with TD and ASD show similarities in some cases. If a child has a low interest in eating, then their parents tend to be more insistent, use more rewards, and offer special meals. On the contrary, a child's high interest in eating harms such parental behaviours. Because an acknowledgement that a relationship exists between the eating behaviours of children and parental actions would make intervening to shape parental attitudes easier, it is recommended that future studies should be carried out to respond to the eating problems of children by working with parents.

Dietary Patterns, Eating Behavior, and Nutrient Intakes of Spanish Preschool Children with Autism Spectrum Disorders

Eating behavior problems are characteristic of children with autism spectrum disorders (ASD) with a highly restricted range of food choices, which may pose an associated risk of nutritional problems. Hence, detailed knowledge of the dietary patterns (DPs) and nutrient intakes of ASD patients is necessary to carry out intervention strategies if required. The present study aimed to determine the DPs and macro-and micronutrient intakes in a sample of Spanish preschool children with ASD compared to typically developing control children. Fifty-four children with ASD (two to six years of age) diagnosed with ASD according to the Diagnostic Manual-5 criteria), and a control group of 57 typically developing children of similar ages were recruited. A validated food frequency questionnaire was used, and the intake of energy and nutrients was estimated through three non-consecutive 24-h dietary registrations. DPs were assessed using principal component analysis and hierarchical clustering analysis. Children with ASD exhibited a DP characterized by high energy and fat intakes and a low intake of vegetables and fruits. Likewise, meat intake of any type, both lean and fatty, was associated with higher consumption of fish and dietary fat. Furthermore, the increased consumption of dairy products was associated with increased consumption of cereals and pasta. In addition, they had frequent consumption of manufactured products with poor nutritional quality, e.g., beverages, sweets, snacks and bakery products. The percentages of children with ASD complying with the adequacy of nutrient intakes were higher for energy, saturated fat, calcium, and vitamin C, and lower for iron, iodine, and vitamins of group B when compared with control children. In conclusion, this study emphasizes the need to assess the DPs and nutrient intakes of children with ASD to correct their alterations and discard some potential nutritional diseases.

Eating Behaviors and Diet Quality in Chinese Preschoolers with and without Autism Spectrum Disorder: A Case-Control Study

OBJECTIVES

To compare mealtime behaviors and diet quality in Chinese preschoolers with autism spectrum disorder (ASD) and typically developing preschoolers in Hong Kong.

STUDY DESIGN

This case-control study included a community sample of 65 families with preschoolers with ASD aged 3-6 years and 65 families with typically developing preschoolers matched for age and sex. Preschoolers' eating behaviors were assessed using the Brief Autism Mealtime Behaviour Inventory and the Preschoolers' Eating Behaviour Questionnaire (CPEBQ). Preschoolers' usual diet and nutrient intake were assessed using a validated food frequency questionnaire. Diet quality and diversity were generated using the Chinese Children Dietary Index total score and diet variety score. Between-group differences in various scales and dietary variables were examined using multivariate linear or logistics regression models adjusting for baseline demographic differences.

RESULTS

Compared with the typically developing group, the ASD group had greater scores in the Brief Autism Mealtime Behaviour Inventory food refusal domain (P < .001), the CPEBQ food fussiness (P = .001) and eating habit (P = .001) domains, and lower CPEBQ exogenous eating score (P = .003) and initiative eating score (P < .001). The Chinese Children Dietary Index total score (P = .001) and diet variety score (P = .005) and intake of soy and soy products (P = .001) were lower in the ASD group compared with the typically developing group.

CONCLUSIONS

Preschoolers with ASD showed more eating and mealtime problems, and lower diet quality and diversity than their typically developing counterparts. Our findings highlight the need for regular monitor and early identification of mealtime behavioral and nutrition problems among preschoolers with ASD.

Development and application of specific questions to classify a child as food texture sensitive

Understanding food texture sensitivity in children is important in guiding food selection. The objective of this work was to develop a short questionnaire that could be completed by parents in nonclinical settings to provide a categorization for food texture sensitivity in children. This study evaluated the distribution of children as texture sensitive (TS) or non-texture sensitive (NTS) and the predictive validity of these questions to explain rejection of specific food textures. Three sets of survey data were examined, including data from a home-use test (HUT) in children with and without Down syndrome (DS), and lingual tactile sensitivity measured by grating orientation task (GOT). From three parent-completed surveys, the use of the questionnaire yielded a similar distribution of children in the TS category (16-22%) as previously reported. TS children (4-36 months) were more likely to reject specific food textures, including chewy, hard, lumpy, and "tough meat" (p < .05). A higher percentage of children with a diagnosis of DS were TS (36.9%). Children who were TS showed increased negative behaviors to foods and ate less than NTS children. In older children (5-12 years), TS children were fussier than NTS children (p < .001). Lingual tactile sensitivity was not significantly different by TS/NTS categorization (p = .458). This study demonstrated that the use of these five questions specific to food texture provides a useful tool in categorizing a child as TS/NTS, with this information being useful in selecting preferred food textures. Future studies involving these TS questions should perform psychometric assessments and measures of criterion validity using other questionnaires.

Feeding and eating problems in children and adolescents with autism: A scoping review

LAY ABSTRACT

Feeding problems, such as picky eating and food avoidance, are common in youth with autism. Other, broader difficulties with feeding and eating (eating disorder symptoms such as restricting food intake or preoccupation with body shape or weight and insistence on specific food presentation) are also common in autistic individuals. Here, we describe the nature and extent of feeding and eating problems in youth with autism. We found no common characteristics (such as severity of autism symptoms) that best describe autistic youth who experience problems with feeding or eating. Almost all studies we reviewed focused on problems with feeding (selective or picky eating), and only a few studies focused on eating disorder symptoms (concern with weight, shape, and/or body image). However, some researchers reported that eating disorder symptoms may occur more often in autistic individuals compared to their peers without autism. Many studies used the terms "feeding" and "eating" problems interchangeably, but understanding the difference between these problems is important for researchers to be consistent, as well as for proper identification and treatment. We suggest future researchers use "eating problems" when behaviors involve preoccupation with food, eating, or body image, and "feeding problems" when this preoccupation is absent. We highlight the importance of understanding whether feeding or eating problems are separate from autism traits, and the role of caregivers and other adults in the child's treatment. Considerations for health-care providers to assist with diagnosis and treatment are also provided.

Tools available to screen for child feeding dysfunction: A systematic review

INTRODUCTION

The aim of this systematic review is to identify existing pediatric feeding screening tools that have been shown to be valid and reliable in identifying feeding dysfunction in children.

METHOD

A database search produced 5862 relevant articles to be screened based on pre-determined inclusion/exclusion criteria. After full text review of 183 articles, 64 articles were included in the review.

RESULTS

Forty-four studies detailed development and validation of unique feeding screening tools for the pediatric population. The remaining twenty studies were validations studies of already developed screening tools.

DISCUSSION

Multiple screening tools identified were effective in determining feeding dysfunction in children. Several tools employed excellent techniques to measure reliability and validity for diverse pediatric populations. Careful consideration of the tools listed in this review will help practitioners determine the best method for feeding screening in their facility.

Promoting physical activity participation and nutrition education through a telehealth intervention for children on the autism spectrum and their caregivers

There is growing empirical support which suggests children on the autism spectrum, as well as their caregivers experience significant health disparities. The global COVID-19 pandemic has only magnified the need to address health among vulnerable populations. While there has been a growing trend in the delivery of telehealth interventions, the delivery of such methods for children on the autism spectrum, and their caregivers remains relatively under examined. The primary goal of PLANE (Physical Literacy And Nutrition Education) is to promote positive trajectories of health for children on the autism spectrum and their primary caregivers through the delivery of a telehealth physical activity and nutrition education program. The study is a pre-experimental analysis of PLANE across 12 months. All activities will be delivered virtually through weekly synchronous and asynchronous programming. A total of 180 participants will be enrolled in this intervention, including children on the autism spectrum and caregivers. Each week a new physical activity skill along with opportunities for recipe assembly will be delivered remotely. Supplemental material will be disseminated online including; step by step directions outlining behavioral skill methodology, opportunities for additional skill practice, and reading material that support weekly topics. Study outcomes will be examined in the parent-child dyad and include rates of overweight/obesity, physical activity, nutrition and quality of life. Finally, feasibility of the telehealth intervention will also be measured. Justification for the conceptualization and delivery of PLANE is well warranted, and PLANE represents a promising intervention which is scalable, sustainable, and replicable.

Impact of eating habits and nutritional status on children with autism spectrum disorder

Objectives

Obesity is common among children with Autism Spectrum Disorder (ASD). They suffer more feeding problems than children with normal developmental milestones. Several kinds of diet are recommended for children with ASD. This study determines the frequency of eating disorders and obesity among such children. We investigate the predisposing factors of eating disorders and examine the effects of consumed food on autism scores.

Methods

In this single-centre, cross-sectional study, 46 children with ASD aged between 2 and 10 years were included. Anthropometric measurements were recorded and Brief Autism Mealtime Behavior Inventory (BAMBI), Autism Behavior Checklist (ABC), and Food Frequency Questionnaire (FFQ) forms were filled in by their parents.

Results

The rates of being overweight and obese were 10.9% and 28.3%, respectively. Food selectivity was observed in 84.8% of the children, and BAMBI food refusal scores were significantly higher for those aged between 2 and 5 years (p = 0.03). Autism scores and consumption of milk, yoghurt, oily seeds, rice/pasta, and fruits (p < 0.05) were significantly correlated. There were also significant differences between these scores and the frequency of consuming eggs, legumes, and other cereals (p < 0.05).

Conclusion

Obesity was more common in children with ASD than typically developed children. Despite the high rate of food selectivity, our findings confirmed that food selectivity could be considered independent of obesity. Further, the diet of patients with ASD must include more fruits, yogurt, eggs, legumes, other cereals, less milk, and less rice/pasta.

Analysis of the Nutrition, Self-Care Skills, and Health Professional Support in Schools of Children with Autism Spectrum Disorder

AIM

This study aimed to determine the nutrition, self-care skills, and health professional support of children with autism spectrum disorder.

METHOD

This is a descriptive and cross-sectional study. The parents of 82 children with autism spectrum disorder agreed to participate as part of a study group in 8 special education schools in 3 districts. The schools were selected on the basis of their levels of sociodemographic development. The data were collected and analysed between September 2016 and July 2017 using a two-section questionnaire developed after a literature review.

RESULTS

The majority of the parents (63.4%) had sufficient knowledge with regard to autism spectrum disorder, but the issues that were most lacking in terms of education were care, nutrition, and skills related to daily living (36.2%). The parents wanted to be educated on “nutrition problems,” and “activities of daily living.” The majority of the children lacked self-care skills (82.9%).

CONCLUSION

The most frequently observed nutrition problem in children with autism spectrum disorder was selective eating. In line with the literature, the majority of the children in this study were found to be unable to care for themselves. School nurses can provide support in terms of nutrition and self-care skills in these schools. School health education programmes for parents can be developed to allow for the more rapid and effective resolution of nutrition and self-care problems.

Eating Challenges in Children with Autism Spectrum Disorder: Development and Validation of the "Aut-Eat" Questionnaire (AEQ)

The Aut-Eat Questionnaire (AEQ) provides a novel and comprehensive assessment of eating problems and patterns in children with ASD. To establish the internal consistency and discriminant validity of the AEQ, parents of children with ASD (n = 105, M_age = 40.85, SD = 15.67 months) or typical development (TD; n = 98, M_age = 50.33, SD = 16.50 months) completed the AEQ. Questionnaire construction, content validity, factor analysis, internal consistency and discriminant validity are reported. The AEQ was reliable with high internal consistency in most domains. Significant differences were found between groups in all domains. The AEQ is a reliable and valid tool and may help to characterize eating difficulties in this population.
