From 2,834 single pregnancies, 1,415 were selected at random to receive ultrasound imaging and continuous wave Doppler flow studies at five points throughout pregnancy (Intensive) and 1,419 to receive a single imaging scan at 18 weeks (Regular), with further scans only as indicated on clinical grounds. There was no significant difference in the rate of Autism Spectrum Disorder between the Regular (9/1,125, 0.8 %) and Intensive (7/1,167, 0.6 %) groups, nor a difference between groups in the level of autistic-like traits in early adulthood. There is no clear link between the frequency and timing of prenatal ultrasound scans and the autism phenotype.

Obesity and associated factors in youth with an autism spectrum disorder / Joanna GRANICH in Autism, 20-8 (November 2016)

We examined the prevalence of overweight/obesity in children and youth with autism spectrum disorder, and associations between weight status and range of factors. Children and youth with autism spectrum disorder aged 2–16?years (n?=?208) and their parents participated in this study. Body mass index was calculated using the Centers for Disease Control and Prevention growth charts and the International Obesity Task Force body mass index cut-offs. The Autism Diagnostic Observation Schedule was administered. Parents completed questionnaires about socio-demographics, diagnosed comorbidities, sleep disturbances, social functioning and medication of youth with autism spectrum disorder. The prevalence of overweight/obesity in participants with autism spectrum disorder was 35%. One quarter of obese children and youth (25.6%) had obese parents.

A Prospective Ultrasound Study of Prenatal Growth in Infant Siblings of Children With Autism / Lisa M. UNWIN in Autism Research, 9-2 (February 2016)  

Public ISBD [article]  inAutism Research > 9-2 (February 2016) . - p.210-216 Titre : A Prospective Ultrasound Study of Prenatal Growth in Infant Siblings of Children With Autism Type de document : Texte imprimé et/ou numérique Auteurs : Lisa M.

WHITEHOUSE, Auteur Article en page(s) : p.210-216 Langues : Anglais (eng) Mots-clés : infants  pediatrics  developmental psychology  prenatal  ultrasound Index. décimale : PER Périodiques Résumé : Numerous studies have observed that a proportion of infants later diagnosed with autism spectrum disorder (ASD) experience accelerated head growth during the first years of life. An emerging methodology for examining the developmental trajectory prior to a diagnosis of ASD is to investigate siblings of affected individuals. The current study is the first prospective investigation of fetal growth in siblings of children with ASD. Two groups of pregnant women were recruited as part of the PRegnancy Investigation of Siblings and Mothers of children with autism cohort in Perth, Western Australia. The “high risk” group (n?=?23) comprised pregnant women who have an existing child with a diagnosis of ASD and the “low risk” group (n?=?36) comprised pregnant mothers who have an existing child who has developed typically. Prenatal ultrasounds were procured at multiple time-points throughout the second- and third-trimesters, enabling an examination of growth trajectories. Growth measurements were then compared for the high- and low-risk fetuses. Mixed linear regression models identified no significant differences between the high- and low-risk fetuses in the rate of prenatal head and body growth throughout the second- and third-trimester (all P-values >0.05). Similarly, there were no significant differences observed when comparing high and low risk groups on a ratio of head circumference relative to body size (??=??0.019, P = 0.75). Future studies may consider looking beyond the macro architecture of the prenatal brain and examine the growth of brain subregions that have been implicated in the presentation of ASD symptoms.

This RCT evaluated the efficacy of one technology-based early intervention programme (Therapy Outcomes By You; TOBY) in young children with ASD. Methods TOBY is an app-based learning curriculum designed for children and parents as a complement to early behavioural intervention. Eighty children (16 female) were recruited to this RCT within 12 months of receiving a diagnosis of ASD (M age = 3.38; SD = 0.69) and randomised to receive either treatment-as-usual (community-based intervention, n = 39) or the TOBY therapy (at least 20 min/day) plus treatment-as-usual (n = 41) for a period of 6 months. Outcomes were assessed at 3 and 6 months postbaseline. (Australian New Zealand Clinical Trials Registry: ACTRN12614000738628; www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=365463). Results Children in the TOBY intervention group averaged 19 min/day engaging with the app in the first 3 months, but only 2 min/day during the second 3 months. There was no group difference in scores on the primary outcome, the Autism Treatment Evaluation Checklist, at either the 3- or 6-month follow-up. However, significant improvements at the 6-month follow-up were observed in the TOBY intervention group relative to the treatment-as-usual group on three secondary outcomes: the Fine Motor and Visual Reception subscales of the Mullen Scale of Early Learning and the Total Words Understood scale of the MacArthur-Bates Communicative Development Index. Statistical trends towards improvement in the TOBY intervention group were observed on measures of adaptive function, although these decreased in magnitude from the 3- to 6-month follow-up. Conclusions This study provides evidence that technology-based interventions may provide a relatively low-cost addition to existing therapist-delivered interventions for children with ASD. However, sustained use of the app over the full 6-month period was a challenge for most families.
