Assessing the heterogeneity of autism spectrum symptoms in a school population / Paula MORALES-HIDALGO in Autism Research, 11-7 (July 2018)  

Public ISBD [article]  inAutism Research > 11-7 (July 2018) . - p.979-988 Titre : Assessing the heterogeneity of autism spectrum symptoms in a school population Type de document : Texte imprimé et/ou numérique Auteurs : Paula MORALES-HIDALGO, Auteur ; P. J. FERRANDO, Auteur ; J. CANALS, Auteur Article en page(s) : p.979-988 Langues : Anglais (eng) Mots-clés : autism spectrum disorders  factor mixture analysis  general child population  symptom profiles Index. décimale : PER Périodiques Résumé : The aim of the present study was to assess whether the nature of the main autistic features (i.e., social communication problems and repetitive and restrictive patterns) are better conceptualized as dimensional or categorical in a school population. The study was based on the teacher ratings of two different age groups: 2,585 children between the ages of 10 and 12 (Primary Education; PE) and 2,502 children between the ages of 3 and 5 (Nursery Education; NE) from 60 mainstream schools. The analyses were based on Factor Mixture Analysis, a novel approach that combines dimensional and categorical features and prevents spurious latent classes from appearing. The results provided evidence of the dimensionality of autism spectrum symptoms in a school age population. The distribution of the symptoms was strongly and positively skewed but continuous; and the prevalence of high-risk symptoms for autism spectrum disorders (ASD) and social-pragmatic communication disorder (SCD) was 7.55% of NE children and 8.74% in PE. A categorical separation between SCD and ASD was not supported by our sample. In view of the results, it is necessary to establish clear cut points for detecting and diagnosing autism and to develop specific and reliable tools capable of assessing symptom severity and functional consequences in children with ASD. Autism Res 2018, 11: 979-988. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: The results of the present study suggest that the distribution of autism spectrum symptoms are continuous and dimensional among school-aged children and thus support the need to establish clear cut-off points for detecting and diagnosing autism. In our sample, the prevalence of high-risk symptoms for autism spectrum disorders and social-pragmatic communication disorder was around 8%.

Differences in food consumption and nutritional intake between children with autism spectrum disorders and typically developing children: A meta-analysis / P. ESTEBAN-FIGUEROLA in Autism, 23-5 (July 2019)  

Public ISBD [article]  inAutism > 23-5 (July 2019) . - p.1079-1095 Titre : Differences in food consumption and nutritional intake between children with autism spectrum disorders and typically developing children: A meta-analysis Type de document : Texte imprimé et/ou numérique Auteurs : P. ESTEBAN-FIGUEROLA, Auteur ; J. CANALS, Auteur ; J. C. FERNANDEZ-CAO, Auteur ; V. ARIJA VAL, Auteur Article en page(s) : p.1079-1095 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  children  food consumption  food selectivity  meta-analysis  nutrition/feeding  nutritional intake  nutritional status Index. décimale : PER Périodiques Résumé : Children with autism spectrum disorders show higher food selectivity, which restricts consumption of some foods and may cause nutritional deficiencies. The aims of this meta-analysis are to determine the overall differences in nutritional intake and food consumption between children with autism spectrum disorder and control (typical development) children, as well as determine the extent to which the nutritional intake and food consumption of autistic children comply with the dietary recommendations. Children with autism spectrum disorder consume less protein (standardized mean difference = -0.27, 95% confidence interval (-0.45, -0.08)), calcium (-0.56 (-0.95, -0.16)), phosphorus (-0.23 (-0.41, -0.04)), selenium (-0.29 (-0.44, -0.13)), vitamin D (-0.34 (-0.57, -0.11)), thiamine (-0.17 (-0.29, -0.05)), riboflavin (-0.25 (-0.45, -0.05)) and vitamin B12 (-0.52 (-0.95, -0.09)) and more polyunsaturated fat acid (0.27 (0.11, 0.44)) and vitamin E (0.28 (0.03, 0.54)) than controls. Autistic children also consume less omega-3 (-0.83 (-1.53, -0.16)) and more fruit (0.35 (0.12, 0.59)) and vegetables (0.35 (0.09, 0.61)) than control children; however, these results must be considered with care due to the low number of studies included in the analysis and the high heterogeneity. The results also suggest a lower intake of calcium, vitamin D and dairy and a higher intake of fruit, vegetables, protein, phosphorus, selenium, thiamine, riboflavin and vitamin B12 than recommended.

Prevalence and Characteristics of Autism Spectrum Disorder Among Spanish School-Age Children / Paula MORALES-HIDALGO in Journal of Autism and Developmental Disorders, 48-9 (September 2018)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 48-9 (September 2018) . - p.3176-3190 Titre : Prevalence and Characteristics of Autism Spectrum Disorder Among Spanish School-Age Children Type de document : Texte imprimé et/ou numérique Auteurs : Paula MORALES-HIDALGO, Auteur ; J.

CANALS, Auteur Article en page(s) : p.3176-3190 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders  Epidemiology  Prevalence  School-age children Index. décimale : PER Périodiques Résumé : The present study aims to assess the prevalence of autism spectrum disorder (ASD) in preschool and school-age children following a two-phase procedure. The screening phase was performed on a sample of 5555 children taking into account parent and teacher information. The individual assessment included the ADI-R, ADOS-2 and Wechsler scales. The estimated prevalence was 1.55% in preschoolers and 1.00% in school-age children. Between 1.84 and 2.59% of the children exhibited subclinical diagnosis. The male-to-female ratio was around 4:1. Most of the children exhibited mild and moderate nuclear symptoms, and the girls showed less severe communication problems. Previous diagnosis was found in 62-71% of the children. Prevalence estimates are close to the 1% international ratings and much higher than previous national reports suggested.
