Public ISBD [article]  inAutism - Open Access > 5-3 [01/06/2015] . - 5 p. Titre : Analysis of Dietary Intake in Children with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Kelly BARNHILL, Auteur ; Alan GUTIERREZ, Auteur ; S. Nathan MARTI, Auteur ; Laura HEWITSON, Auteur Article en page(s) : 5 p. Langues : Anglais (eng) Mots-clés : Autism  Nutrition  Diet  Macronutrient  Micronutrient  Vitamin Index. décimale : PER Périodiques Résumé : Parents and caregivers of children with Autism Spectrum Disorder (ASD) often report that their children are picky, restricted, and problem eaters. Additionally, it has been reported that children with ASD often experience gastrointestinal problems such as constipation, diarrhea, flatulence, and cramping, bloating, and diffuse pain. These factors raise concern for nutritional status of children with ASD, given that the refusal to consume particular foods coupled with the inability to tolerate, digest, and absorb these foods can compromise an individual’s overall nutrition status. The aim of our study was to evaluate dietary intake in a group of 120 children aged 2-14 years who were served in an outpatient clinic over 18 months’ time. Anthropometric data and 3-day food diaries were collected and evaluated by a licensed, registered dietician. The results indicate that the majority of participants consumed adequate calories, protein, fats, and carbohydrates. However, the majority of participants were deficient in vitamins A, D, B1, and folate, as well as calcium, magnesium, iodine, and potassium. Essential fatty acid intake was insufficient for all but 6 of the participants. Overall, the study revealed deficits in several key nutrients for the majority of participants.

Brief Report: Implementation of a Specific Carbohydrate Diet for a Child with Autism Spectrum Disorder and Fragile X Syndrome / Kelly BARNHILL in Journal of Autism and Developmental Disorders, 50-5 (May 2020)

Data relating to anthropometrics, dietary intake, blood markers, gastrointestinal (GI) symptoms, sleep issues, and behavioral concerns were gathered at baseline and after 4 months of dietary intervention. The dietary intervention was well tolerated. Improvements in nutrient status, GI symptoms, and behavioral domains were reported. The use of the SCD protocol in children with ASD/FXS and GI symptoms warrants further investigation.

Criterion-related validity of the PDDBI: Comparison with the ADOS-2 / Claire SCHUTTE in Research in Autism Spectrum Disorders, 64 (August 2019)

This study examined criterion related validity of the PDDBI through comparison with the Autism Diagnostic Observation Schedule-Second Edition (ADOS-2) in 104 children ages 2–11 years. A positive relationship between the PDDBI Autism Composite and all ADOS-2 scores, as well as some subscale correlations, supported convergent validity of the PDDBI as a measure of ASD symptomatology. Additionally, a significant negative relationship between PDDBI adaptive subscales and ADOS-2 scores reinforced divergent validity. These results add to the literature on the validity of the PDDBI as a measure of ASD symptoms.

Dietary status and nutrient intake of children with autism spectrum disorder: A case-control study / Kelly BARNHILL in Research in Autism Spectrum Disorders, 50 (June 2018)

Additionally, it has been reported that children with ASD often experience gastrointestinal problems such as constipation, diarrhea, flatulence, cramping, bloating, and pain. These factors raise concerns for the nutritional status of children with ASD, given that refusal to consume particular foods coupled with the inability to tolerate, digest, and/or absorb these foods can compromise overall nutritional status. Method This case-control study investigated dietary intake of 86 children with ASD aged 2–8 years and 57 age-matched peers without ASD. Caregivers of participants who met inclusion criteria completed a health history questionnaire, provided information on dietary intake and feeding behavior, and completed a nutrition physical. Results The majority of participants (both with and without ASD) met or exceeded macronutrient intake recommendations and dietary percentages for total energy, protein, carbohydrate, and fat consumption. Approximately 25% of participants consumed an inadequate or borderline amount of total calories per day based on Dietary Reference Intake (DRI) guidelines created by US Institute of Medicine (IOM). The majority of participants consumed inadequate amounts of vitamins A, D, E, folic acid and calcium. Furthermore, children with ASD consumed lower levels of protein and calcium, and were deficient in a number of B vitamins, including B1, B2, B3, B6, and folate, compared to similarly-aged children without ASD. Conclusion Given the impact of nutrition on growth and health status, a formal dietary assessment for all children with ASD is recommended.

Neuropathology and Animal Models of Autism: Genetic and Environmental Factors / Bharathi S. GADAD in Autism Research and Treatment, (October 2013)  

Public ISBD [article]  inAutism Research and Treatment > (October 2013) . - 12 p. Titre : Neuropathology and Animal Models of Autism: Genetic and Environmental Factors Type de document : Texte imprimé et/ou numérique Auteurs : Bharathi S. GADAD, Auteur ; Laura HEWITSON, Auteur ; Keith A. YOUNG, Auteur ; Dwight C. GERMAN, Auteur Année de publication : 2013 Article en page(s) : 12 p. Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Autism is a heterogeneous behaviorally defined neurodevelopmental disorder. It is defined by the presence of marked social deficits, specific language abnormalities, and stereotyped repetitive patterns of behavior. Because of the variability in the behavioral phenotype of the disorder among patients, the term autism spectrum disorder has been established. In the first part of this review, we provide an overview of neuropathological findings from studies of autism postmortem brains and identify the cerebellum as one of the key brain regions that can play a role in the autism phenotype. We review research findings that indicate possible links between the environment and autism including the role of mercury and immune-related factors. Because both genes and environment can alter the structure of the developing brain in different ways, it is not surprising that there is heterogeneity in the behavioral and neuropathological phenotypes of autism spectrum disorders. Finally, we describe animal models of autism that occur following insertion of different autism-related genes and exposure to environmental factors, highlighting those models which exhibit both autism-like behavior and neuropathology.
