Feeding and Swallowing Issues in Autism Spectrum Disorders

Application of the international classification of functioning, disability, and health in autism and attention-deficit hyperactivity disorder: A scoping review

LAY ABSTRACT

The International Classification of Functioning, Disability, and Health (ICF) is a framework designed by the World Health Organization (WHO) to help different sectors, such as healthcare, social services, education, and policy, understand how people with health-related issues function (do the things they want to and need to do) in their daily lives. This framework has also been used to guide clinical practice and research in autism and attention-deficit hyperactivity disorder (ADHD). To make it more practical, shorter versions of the ICF called Core Sets have been developed. We wanted to explore how the ICF and the ICF Core Sets have been used in research relating to autism and ADHD. We looked at the research that had been previously published on this topic by conducting a systematic search and review. Seventy-eight studies meeting our criteria were included in our review. Results show that the ICF has been applied in many ways across various contexts. However, most of the research has focused on autism, mainly involving children. The review highlights that although the ICF was used in some studies, the underlying philosophies of the framework were not always followed. The medical perspective still influenced the way research was done and interpreted. Nevertheless, using the ICF in the right way can help shift research on neurodevelopmental conditions like autism and ADHD toward a more holistic approach, moving away from solely focusing on medical aspects.

Diet, growth, nutritional status and predictors of severity of feeding difficulties in autistic children with co-occurring pediatric feeding disorder

BACKGROUND

Feeding difficulties are commonly reported in autistic children. However, there is limited data on the presentation, severity, and impact of feeding difficulties in autistic children in Asia.

AIMS

To describe the dietary patterns, growth and nutritional status of autistic children with pediatric feeding disorder (PFD), and identify factors associated with more severe feeding difficulties.

STUDY DESIGN

A retrospective review of electronic medical records.

SUBJECTS

Autistic children (aged between 0 and 18 years) with PFD, who attended a multidisciplinary feeding clinic between August 2013 and December 2022.

OUTCOME MEASURES

The children's parents provided a 3-day food diary, which was verified by the dietitian and analyzed for their nutritional content using Foodworks 10 Professional. Food selectivity was classified as mild, moderate or severe, based on the number of food groups accepted and the absolute number of foods accepted in each group. Information regarding demographics, height, weight, medical information, developmental history (autism diagnosis, cognition, adaptive skills) and relevant nutritional bloodwork were collected. Parents also completed two validated questionnaires (the Behavioral Pediatrics Feeding Assessment Scale (BPFAS), which assessed childhood mealtime behaviors; and the Caregiver Feeding Style Questionnaire (CFSQ), which determined caregiver/ parental feeding styles). Factors associated with higher BPFAS total frequency scores (TFS) (representing more severe feeding difficulties) and food selectivity were analyzed.

RESULTS

There were a total of 98 patients (82 males), with mean ± SD (range) age of 59.2 ± 27.5 (17-169) months. They had mild (19.4 %), moderate (22.4 %) and severe (58.2 %) food selectivity, respectively. While the majority had normal weight (84.7 %) and height (88.8 %) for age, 69.4 % had diets deficient in calories, macronutrients or micronutrients (iron, calcium). Comparison between groups according to parental feeding style found that there was a significant difference in BFPAS TFS between different parental feeding styles (p < 0.001). Post-hoc testing revealed that parents who reported an authoritarian parental feeding style on the CFSQ were significantly more likely to report higher frequencies of difficult feeding behaviors on the BPFAS (98.3 ± 15.8), while an uninvolved parental feeding style was associated with the lowest BPFAS TFS (80.9 ± 11.0), Bonferroni-adjusted p < 0.001; indulgent (p = 0.012) and authoritative (p = 0.096). Intellectual impairment and Malay ethnicity were associated with more severe food selectivity [adjusted odds ratio 123.7 (95 % CI 3.09-4945.4, p = 0.01) and 38.0 (95 % CI 1.35-1074.18, p = 0.03)], respectively.

CONCLUSIONS

In this retrospective cohort, autistic children with PFD were at significant nutritional risk despite demonstrating normal growth patterns, with specific patient profiles being associated with more severe feeding difficulties.

Effect of Sensory Adapted Dental Environment (SADE) on physiological and behavioral parameters related to stress and anxiety in children with Autism Spectrum Disorder (ASD) undergoing dental treatment: A systematic review and meta-analysis

BACKGROUND

Children with autism exhibit a higher general and dental anxiety, due to altered sensory sensibilities.

AIM

This current systematic review aims to evaluate the effectiveness of Sensory adapted dental environment (SADE) over regular dental environment (RDE) on behavioral, physiological stress and overt anxiety in children with autism spectrum disorders (ASDs).

MATERIALS AND METHODS

Prospero registered (CRD42024508336). PubMed, Cochrane, Scopus databases are searched from years January 1, 1980-January 1, 2024 using pre-defined search strategy.

RESULTS

A total of 269 titles, were obtained from the included databases after application of filters, exclusion of duplicates and reviews and irrelevant articles led to the final inclusion of 12 articles for full text screening from which, three studies sustained the targeted PICO search.

CONCLUSION

Skin conductance level (parameter indicating physiological stress) is lower in SADE environment in children with ASD, other behavior stress related parameters there is no significant difference between SADE and RDE environments.

A scoping review of Australian nutrition resources for feeding children under 5 years of age

INTRODUCTION

This review identified and appraised Australian open-access online resources relating to feeding and nutrition during the first 5 years of life.

METHODS

Eligible resources were identified by hand searching plus a targeted search of pertinent source websites (government, hospitals and health services, peak bodies, and nutrition organisations) published in English with/without translations to other languages between 2012 and 2022. Search terms relating to the population (children) AND topic (nutrition OR feeding) were entered into Google and Bing. Critical appraisal of each resource was conducted using a modified version of the Centres for Disease Control and Prevention Clear Communication Index.

RESULTS

The search identified 1327 nutrition resources, of which 1067 were appraised. Forty-five percent were paper-based resources, 47% were online content only, and 8% audio-visual resources. Almost half of the resources (45%) broadly addressed the 0-5 years age range, and 24% provided information on breast or formula feeding. Limited resources were found specifically addressing growth and development (5%) and introducing solids (8%). Only 10% of resources were culturally tailored and only 3% were translated into a language other than English. Appraisal showed the majority included visual cues and appropriate language, but less included images to support the main message of the resource.

DISCUSSION

Although there were a large volume of evidence-based nutrition resources available in Australia for feeding children under 5 years, they were highly dispersed and of varying quality. Collating and presenting these resources in an open-access resource hub would empower families and education and health professionals in the nutritional care of young children.

Autistic traits and eating behaviors in Chinese preschoolers: Role of sensory profiles and home environment

OBJECTIVE

This study aims to 1) explore the association between autistic traits and eating behaviors in Chinese preschoolers; 2) explore the mediating role of sensory processing patterns on the relation of autistic traits and eating-related behaviors; and 3) examine home nurturing environment as a moderator between autistic traits and eating-related behaviors. We hypothesize that there is a significant association between autistic traits and eating behaviors, which is mediated by sensory processing patterns and moderated by the home nurturing environment.

METHOD

509 children aged 3-4 years participated in this cross-sectional research. They were assessed using the Social Responsiveness Scale-Second Edition (SRS-2) for autistic traits, the Chinese Preschoolers' Eating Behavior Questionnaire (CPEBQ) for eating-related behaviors, the Short Sensory Profile-Second Edition (SSP-2) for sensory processing patterns, and the Children Home Nurture Environment Questionnaire (CHNEQ) for home nurturing environment. Mediation regression analyses were used to examine the role of sensory processing patterns, while moderation analyses to examine the role of home nurturing environment.

RESULTS

We observed a positive association between autistic traits and eating behavior problems among typically developed children. Sensory processing patterns significantly mediated the impact of autistic traits on children's eating-related behaviors and home nurturing environment also moderated this relationship.

DISCUSSION

Our research suggests that Chinese preschoolers with higher autistic traits may face more eating challenges when they possess more heightened sensory processing patterns, while living in supportive home environments helps to improve their eating behaviors. These findings contribute to the understanding of how and to what extent eating problems are influenced by autistic traits, and they offer insight into the alleviation of eating problems from the perspectives of sensory patterns and family nurturing environments.

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 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.

The "FEEDS (FEeding Eating Deglutition Skills)" over Time Study in Cardiofaciocutaneous Syndrome

Feeding, eating and deglutition difficulties are key concerns in patients with cardiofaciocutaneous syndrome (CFCS). This study intends to quantify the development of feeding skills from birth to adulthood in patients with CFCS. Twenty-seven patients (eight males; mean age: 16.7 ± 8.3 years; median age: 15 years, age range: 1.5-38 years) with molecularly confirmed clinical diagnosis of CFCS were prospectively recruited from the Rare Disease Unit, Paediatrics Department, Fondazione Policlinico Agostino Gemelli-IRCCS, Rome, Italy, over a one-year period. Pathogenic variants along with key information regarding oro-motor features were collected. Sialorrhea was quantified using the Drooling Quotient 5. Feeding abilities were screened using the Italian version of the Montreal Children's Hospital Feeding Scale (I-MCH-FS). The oral sensory processing section of the Sensory Profile completed the assessment. Mild-to-profuse drooling was experienced by 25% of patients, and food taste selectivity was a constant during infancy (65%), with persistence even beyond adolescence. Nineteen percent of participants with long-term enteral feeding dependency had BRAF, KRAS and MAP2K1 mutations. These findings document that mealtime challenges in CFCS do not remain restricted only to the paediatric age, and that supportive care until adulthood plays a key role.
