Detecting Feeding Problems in Young Children with Autism Spectrum Disorder

Feeding Behaviors in Infants and Toddlers Later Diagnosed with Autism Spectrum Disorder: A Systematic Review

Children with autism spectrum disorder (ASD) are five times more likely to have feeding difficulties than neurotypical peers, although the majority of evidence describes feeding difficulty in children age 2 years and older. The purpose of this study is to systematically review the literature on feeding characteristics of children age 0-24 months who were later diagnosed with ASD with an emphasis on the measurement tools used to assess these feeding behaviors. We conducted a systematic review of the literature using PRISMA guidelines. Using selected keywords, a search was conducted using PubMed, PsycINFO, and CINAHL databases for relevant articles to identify feeding characteristics in infants and toddlers (age 0-24 months) later diagnosed with ASD. Sixteen studies were selected for this review by two independent reviewers. Among the selected studies, feeding difficulties were reported in all infant oral feeding modalities (breastfeeding, bottle feeding, and complementary feeding) by infants later diagnosed with ASD. However, the evidence was conflicting among studies regarding feeding characteristics, such as sucking differences while breastfeeding, use of the spoon with feedings, and preference of solid food texture, that presented in infants later diagnosed with ASD. A lack of consistent measurement of feeding behaviors in infants later diagnosed with ASD contributes to the difficulty in comparison across studies. Future research should focus on developing targeted, validated instruments for measuring feeding difficulty in this population with emphasis on breastfeeding and bottle feeding difficulty.

Nutritional status and eating behavior of children with autism spectrum disorders in Vietnam: A case-control study

Background: Atypical eating behaviors and feeding issues are common in children with autism spectrum disorder (ASD). Aim: This study aims to evaluate the nutritional status and eating behavior of the ASD and typically developing groups. Methods: A case-control study was conducted from January to April 2019 in Nghe An, Vietnam. A total of 93 children in each group participated in the study with their main caregivers. We applied the Children's Eating Behavior Inventory (CEBI) to evaluate the eating behaviors of children. Results: Overweight and obesity in ASD children accounted for 41.9%. The CEBI score and %CEBI of the ASD group was higher than that of the control group (104.0 ± 14.2 and 91.3 ± 8.3; 24.1 ± 21.4 and 5.0 ± 11.8, respectively). Most of the adverse mealtime behaviors of ASD children focused on excessive duration (52.7%), distraction (40.9%), and food refusal (39.8%). In total 88.2% of caregivers had to comfort their ASD children at every meal, followed by threatening, scolding, or punishing children if they refused to eat (57.0%). Conclusion: Being overweight/obese and having eating behavior difficulties were prevalent among ASD children in Vietnam. Safer alternatives, such as lifestyle measures and seeking help from a nutritional therapist, can help ASD children reduce weight and modify their erroneous feeding habits.

Biochemical Markers as Predictors of Health Outcomes in Autism Spectrum Disorder: A Comprehensive Systematic Review and Meta-analysis

Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder with an increasing prevalence worldwide, including in Saudi Arabia. Emerging evidence suggests that biochemical markers, such as oxidative stress indicators, neurotransmitter levels, and lipid profiles, play a significant role in ASD's pathology and may also elevate cardiovascular and metabolic risks in affected individuals. This systematic review and meta-analysis synthesize current findings on these biomarkers, with a particular focus on the Saudi population, to elucidate their relationship with ASD pathology and associated health outcomes. Following the PRISMA guidelines, data from 41 studies on oxidative stress markers, neurotransmitters, lipid profiles, and immune markers were analyzed. Searches were conducted across major databases, including PubMed, Scopus, Web of Science, and Embase, and effect sizes were calculated using standardized mean differences with a 95% confidence interval. To further interpret the data, bioinformatics tools such as Reactome, Panther, and STRING were employed to analyze biomarker pathways. The results highlight a significant association between elevated oxidative stress and mitochondrial dysfunction in individuals with ASD, with profound effects on gastrointestinal and mitochondrial health. These biochemical abnormalities disrupt synaptic plasticity and drive chronic neuroinflammation, which impairs neurodevelopmental processes, contributing to the pathology of ASD. The meta-analysis reveals minimal heterogeneity (I2 = 0.02%) and limited publication bias, supporting the reliability of these associations. The findings underscore the need for a multidisciplinary approach to ASD management in Saudi Arabia, emphasizing biomarker-based diagnostics and personalized treatment strategies. Future research directions include developing individualized diagnostic and therapeutic frameworks utilizing these biomarkers to enhance ASD-related health outcomes.

Research Tools for Eating Behavior in People with Autism Spectrum Disorder (ASD)

OBJECTIVE

To identify the tools used to assess eating behaviors in individuals with Autism Spectrum Disorder (ASD) and summarize their distribution, citation rates, journal publication, JCR scores, and psychometric properties.

METHODS

A literature review was conducted to identify studies on eating behavior in individuals with ASD. The search included various descriptors and combinations of keywords in databases such as Medline/PubMed, Science Direct, Scopus, SciELO, and Web of Science. The studies were filtered to focus on articles published in the last five years. Thirty-seven relevant studies were identified and analyzed to summarize the tools used, their distribution in the literature, citation rates, and psychometric properties.

RESULTS

Thirty-seven relevant studies were identified. The Journal of Autism and Developmental Disorders published the most studies (5). The Brief Autism Mealtime Behavior Inventory (BAMBI) was the most frequently used instrument, appearing in 15 studies, followed by the Behavioral Pediatrics Feeding Assessment Scale (BPFAS) in 8 studies. Both instruments demonstrated solid psychometric properties, with BAMBI showing good internal consistency (α = 0.88) and BPFAS a Cronbach's alpha of 0.82.

CONCLUSION

Most of the instruments used in studies on eating behavior in individuals with ASD demonstrate satisfactory psychometric properties. BAMBI and BPFAS stand out for their widespread use but are limited to covering only specific age ranges.

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.

Determination of Nutrient Intake and Dietary Antioxidant Capacity in Autism Spectrum Disorder: A Case-Control Study

The aim of this study was to evaluate the nutrient intake and dietary antioxidant capacity of children and adolescents with ASD. The study included 38 children and adolescents with ASD aged 6-18 years and 38 gender and age-matched peers without ASD. Caregivers of participants who met inclusion criteria completed a questionnaire form, three-day food consumption record and antioxidant nutrient questionnaire. There were 26 (68.4%) boys and 12 (31.6%) girls in both groups and mean age of participants with and without ASD was 10.9 ± 4.03 years versus 11.1 ± 4.09 years, respectively. The average intake of carbohydrates, vitamin D, calcium, sodium and selenium was lower in participants with ASD than in participants without ASD (p < 0.05). In both groups, dietary fiber, vitamin D, potassium, calcium and selenium intake insufficiency were high, and there was a significant difference between the two groups in terms of carbohydrate, omega 3, vitamin D and sodium intake insufficiency. Considering the antioxidant intakes of the participants, the median value of dietary antioxidant capacity from food consumption record of participants with and without ASD was 3.2 (1.9) mmol versus 4.3 (1.9) mmol, respectively, whereas the dietary antioxidant capacity from antioxidant nutrient questionnaire was 3.5 (2.9) mmol versus 4.8 (2.7) mmol, respectively (p < 0.05). It is predicted that providing nutritional counseling and regulation of diet, especially keeping the antioxidant capacity of diets high, may be effective in reducing some of the symptoms of ASD.

Cross-Cultural Adaptation and Validation of the Greek Cypriot Montreal Children's Hospital Feeding Scale

INTRODUCTION

Assessing pediatric feeding disorders (PFD) is essential for a child's development to prevent severe consequences. The assessment procedures for PFD may include parents' questionnaires such as the Montreal Children's Hospital Feeding Scale (MCH-FS). The aim of this study was the cross-cultural adaptation of the MCH-FS to the Greek language.

METHODS

One hundred parents of Greek Cypriot children with PFD (clinical group) and 100 parents of healthy Greek Cypriot children (control group) aged 6 months to 16 years old participated in the study and completed the MCH-FS. World Health Organization (WHO) guidelines were implemented for translation and cultural adaptation.

RESULTS

The internal consistency was excellent, α = 0.85 (ICC: 0.817-0.891). Content validity was significant (S-CVI = 1) with an agreement equal to 14. A strong and significant correlation of MCH-FS was computed according to principal component analysis (14 items ranging between -0.6 and 0.7). The Kaiser-Meyer-Olkin factor analysis was equal to 0.91 with substantial correlations (Bartlett's test = 0.001, 654,804). The MCH-FS cut-off point between the two groups was 38.00 (AUC: 0.901 [95% CI: 0.859-0.942], p < 0.001; sensitivity = 0.800 and 1-specificity = 0.630). A statistically significant difference between the two groups was observed for the MCH-FS total score, with the clinical group scoring higher (U = 992.00, p < 0.001). Likewise, the same differences were observed among children with different PFD, H (3) = 96.715, p < 0.001.

CONCLUSION

The MCH-FS had good psychometric properties in its current form in Greek. It is suggested that the MCH-FS can be used as a valid tool for children with PFD in the Greek Cypriot population.

Assessment Methods for Problematic Eating Behaviors in Children and Adolescents With Autism Spectrum Disorder

Autism spectrum disorder (ASD) can be associated with eating problems. However, currently, there is a lack of established guidelines for assessing and addressing eating behaviors in individuals with ASD. This gap in research exists due to the challenges associated with using traditional assessment methods, which may lead to discrepancies in responses and unintentional potential biases from caregivers. In this review, we provided a comprehensive overview of various eating behaviors commonly observed in individuals with ASD. These behaviors include 1) food neophobia, 2) selective eating, 3) binge eating, 4) food avoidance, 5) chewing and swallowing problems, 6) pica, 7) rumination, 8) rituals, and 9) problematic behaviors. Furthermore, we provide a perspective of utilizing digital tools: 1) augmentative and alternative communication; 2) ecological momentary assessment; and 3) video analysis, behavioral analysis, and facial expression analysis. This review explores existing assessment methods and suggests novel assessment aiding together.

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.

Oromotor skills in autism spectrum disorder: A scoping review

Oromotor functioning plays a foundational role in spoken communication and feeding, two areas of significant difficulty for many autistic individuals. However, despite years of research and established differences in gross and fine motor skills in this population, there is currently no clear consensus regarding the presence or nature of oral motor control deficits in autistic individuals. In this scoping review, we summarize research published between 1994 and 2022 to answer the following research questions: (1) What methods have been used to investigate oromotor functioning in autistic individuals? (2) Which oromotor behaviors have been investigated in this population? and (3) What conclusions can be drawn regarding oromotor skills in this population? Seven online databases were searched resulting in 107 studies meeting our inclusion criteria. Included studies varied widely in sample characteristics, behaviors analyzed, and research methodology. The large majority (81%) of included studies report a significant oromotor abnormality related to speech production, nonspeech oromotor skills, or feeding within a sample of autistic individuals based on age norms or in comparison to a control group. We examine these findings to identify trends, address methodological aspects hindering cross-study synthesis and generalization, and provide suggestions for future research.

Assessment of Feeding Behaviors and Parents' Frustrations of Children with Autism Spectrum Disorder in Lebanon: A Case-Control Study

Children with autism spectrum disorder (ASD) exhibit restrictive and repetitive behaviors that affect their eating habits. The purpose of this study is to identify the behavioral feeding problems and eating habits among ASD children compared to typically developed (TD) children age/gender-matched controls, along with their parents'/caregivers' strategies for dealing with them. It included 43 ASD children and 43 TD children aged two to eleven years. The analysis was performed based on two valid questionnaires: the Behavior Pediatrics Feeding Assessment Scale (BPFA) and "My Child Eating Habits" (MCEH). The BPFA and MCEH scores conceded three manifestations that fall into food selectivity and problematic mealtime behavior in both groups of children. Compared to TD children, children with ASD exhibited higher BPFA scores, which indicated food-related behavioral and skill-based problems (p = 0.004). Children with ASD were less likely to consume fruits, vegetables, and milk than TD children, which may lead to nutritional deficiencies (p = 0.003, p = 0.003, and p = 0.010, respectively). Parents of ASD children were concerned about their behavioral problems and expressed their intention of an early intervention. These findings highlight the importance of nutritional clinical routines that incorporate the evaluation of the nutritional status and feeding behaviors of ASD children.

Interrelated development of autism spectrum disorder symptoms and eating problems in childhood: a population-based cohort

Eating problems, such as food selectivity or picky eating, are thought to be an epiphenomenon of autism spectrum disorders (ASD). Yet eating problems are also common in the general pediatric population and overlap with ASD symptoms. However, the temporal association between ASD symptoms and eating problems is poorly understood. This study examines the bidirectional association between ASD symptoms and eating problems across child development, and investigates whether these associations differ by child sex. Participants (N = 4,930) were from the population-based Generation R Study. Parents reported their child's ASD symptoms and eating problems using the Child Behavior Checklist at 5 assessments from toddlerhood to adolescence (1.5 to 14 years, 50% girls). A Random Intercept Cross-Lagged Panel Model was used to examine the lagged associations between ASD symptoms and eating problems at the within-person level, controlling for stable, trait-like differences at the between-person level. At the between-person level, there was a strong correlation between ASD symptoms and eating problems (β = .48, 95% CI: 0.38 to 0.57). Controlling for these between-person effects, there was limited evidence for consistent, predictive effects of ASD symptoms and eating problems at the within-person level. Associations did not differ by child sex. Findings suggest that ASD symptoms and eating problems may represent a cluster of traits that are highly stable from early childhood to adolescence, which have a minimal reciprocal effect at the individual-level. Future research could focus on these trait-like qualities to inform the development of supportive, family-focused interventions.

Managing Feeding Problems in Persons with Autism using Behavioral Interventions

Background

This study examined the effectiveness of behavioral intervention on feeding problem in persons with autism in Ibadan, Nigeria.

Methodology

Pretest-posttest, control group quasi-experimental research with a 2x2 factorial matrix. Data was collected with the Feeding Behavioral Analysis Test. Ten (10) persons with non-verbal autism and evidence of poor feeding habits (selectivity by food type) attending a residential school in Ibadan participated in the study. The one-way between-subjects Analysis of Co-variance (ANCOVA) was used to determine the effectiveness of the behavioral intervention.

Results

Positive reinforcement was effective in reducing feeding problem in children with autism (F(1, 7) = 3.023, p<0.05), compared to the control group (t (8)= -5.24, p<.05). Further analysis revealed significant main effect of the age of the participants (F(1,7) = 5.343, p<0.05).

Conclusions

there is a need for teachers, counsellors, caregivers, parents, minders and clinical psychologists to adopt positive reinforcement in the management of feeding problems among persons with autism.

Feeding problems, age of introduction of complementary food and autism symptom in children with autism spectrum disorder

In this cross-sectional study, 84 children with autism spectrum disorder (ASD) and 77 healthy subjects showing typical development (TD) were reviewed. Parents reviewed the age of introduction of complementary foods (CFs), completed a demographic, diet behavior questionnaire and the Autism Behavior Checklist (ABC). The results showed that the age of introduction of CFs was later in children with ASD than their TD counterparts. The age of introduction of CFs in ASD group was positively correlated with feeding problem. While the correlation was not observed in TD group. Children in the ASD group had higher total scores of the diet behavior questionnaire and all four subdomains (poor eating ability, mealtime eating behavior, food selectivity, and parental feeding behavior). ASD symptoms were clearly associated with feeding problems. The sensory subdomain score in ABC was positively correlated with poor eating ability, mealtime behavior and total score of the diet behavior questionnaire. The social self-care subdomain score was positively correlated with food selectivity. The interaction subdomain score was negative correlated with parental feeding behavior and total score of the diet behavior questionnaire. Further studies are required to establish the utility of delayed CFs introduction and/or early feeding problems as potential indicators of ASD.

Child Autistic Traits, Food Selectivity, and Diet Quality: A Population-Based Study

BACKGROUND

Children with Autism Spectrum Disorders (ASDs) tend to be selective in their food intake, which may compromise their diet quality. While ASD diagnoses capture severe levels of impairment, autistic traits vary on a continuum throughout the population. Yet, little is known about how autistic traits relate to diet quality at the population level.

OBJECTIVES

This study examines the association between autistic traits in early childhood and diet quality in mid-childhood and explores the mediating role of food selectivity.

METHODS

Participants were children (n = 4092) from the population-based Generation R Study. Parents reported their child's autistic traits at 1.5, 3, and 6 years; food selectivity at 4 years; and food intake at 8 years, from which a diet quality score was derived. Associations of autistic traits and the autistic trait trajectory (identified using Latent Class Growth Modelling) with diet quality were examined using multiple linear regression models. The indirect effect of food selectivity in the association between autistic traits at 1.5 years and diet quality was examined using mediation analysis.

RESULTS

Autistic traits were associated with diet quality (e.g., 1.5 years: β = -0.09; 95% CI: -0.13 to -0.06). Two classes captured the autistic trait trajectories from 1.5 to 6 years: children with "low and stable" (95%) and "high and increasing" (5%) mean scores. Children in the high and increasing group had poorer diet quality than those in the low and stable group (β = -0.28; 95% CI: -0.44 to -0.11). Food selectivity mediated the association between autistic traits at 1.5 years and diet quality at 8 years (βindirect = -0.03; 95% CI: -0.03 to -0.02).

CONCLUSIONS

Autistic traits in early childhood are associated with poorer diet quality in mid-childhood, and food selectivity appears to mediate this association. Interventions intended to optimize nutrition in children with elevated autistic traits may integrate behavioral strategies to support parents' responding to their child's food selectivity.

Severe OCD Exacerbation in a Patient with Autism Spectrum Disorder: A Case Report

Autism Spectrum disorder (ASD) is a neurodevelopmental disorder characterized by impairments in social communication and social interaction, repetitive and stereotyped behaviors, and/or sensory aberrations. On the other hand, obsessive-compulsive disorder (OCD) is characterized by the presence of obsessions and/or compulsions. In consideration of these distinct pathologies, research suggests that anxiety disorders and OCD are highly prevalent in individuals with ASD. This case report will discuss an adolescent patient with ASD and OCD who experiences an exacerbation, most notably, in his symptoms of OCD. We outline the hospital course of a 13 year-old male who ultimately requires nasogastric (NG) tube feeding resulting from an acute worsening in symptoms and refusal of oral intake during the COVID-19 pandemic. The patient demonstrated significant improvement in symptoms following the administration of high-dose selective serotonin reuptake inhibitor (SSRI) and low-dose antipsychotic therapy.

Feeding Difficulty Among Chinese Toddlers Aged 1-3 Years and Its Association With Health and Development

Feeding problems are biopsychosocial in nature and have a great influence on children's growth. The aim of this study was to profile the status and possible influencing factors of feeding difficulty among normal Chinese toddlers, and to investigate its association with health and development. This study is a part of the Young Investigation (YI study) conducted in 10 cities in China. Data from 924 children aged 1-3 years were analyzed. Data on socio-demographic factors, feeding behaviors, self-reported diseases, and anthropometry parameters were collected. Blood samples were drawn to determine hemoglobin levels. Feeding difficulty was evaluated by the Montreal Children's Hospital Feeding Scale (MCH-FS). Ages and Stages Questionnaires, Third Edition (ASQ-3) were used to assess developmental progress. Multivariable analyses were performed to explore the potential associations. The mean total score of the MCH-FS was 35.21 ± 12.90 and the highest scored item was "acting up/making a big fuss during mealtimes." Feeding difficulty occurred more often among children with picky eating behavior or whose caregivers once used the strategy of pre-mastication. Children with feeding difficulty had lower intakes of cereals, vegetables, and fruits, and were more likely to suffer from diarrhea (OR, 2.04; 95%CI: 1.32, 3.11) or constipation (OR, 2.04; 95%CI: 1.27, 3.24), but not anemia. Feeding difficulty was also negatively associated with weight, height, head circumference and mid-upper-arm circumference-related Z-scores (P all < 0.05). In addition, it was related to poorer fine motor skills, personal and social skills, and total scores of ASQ-3 (β, -9.00; 95%CI: -15.11, -2.89). Feeding difficulty assessed by MCH-FS showed a negative association with children's health and development, supporting the need for early identification.
