Are Prenatal Ultrasound Scans Associated with the Autism Phenotype? Follow-up of a Randomised Controlled Trial / Yonit K. STOCH in Journal of Autism and Developmental Disorders, 42-12 (December 2012)
[article]
Titre : Are Prenatal Ultrasound Scans Associated with the Autism Phenotype? Follow-up of a Randomised Controlled Trial Type de document : Texte imprimé et/ou numérique Auteurs : Yonit K. STOCH, Auteur ; Cori J. WILLIAMS, Auteur ; Joanna GRANICH, Auteur ; Anna M. HUNT, Auteur ; Lou I. LANDAU, Auteur ; John P. NEWNHAM, Auteur ; Andrew J. O. WHITEHOUSE, Auteur Article en page(s) : p.2693-2701 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Autism Prenatal Ultrasonography Obstetric Environment Index. décimale : PER Périodiques Résumé : An existing randomised controlled trial was used to investigate whether multiple ultrasound scans may be associated with the autism phenotype. 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.

HUNT, Auteur ; Joanna GRANICH, Auteur ; Peter JACOBY, Auteur ; Cheryl DISSANAYAKE, Auteur ; Craig E. PENNELL, Auteur ; Martha HICKEY, Auteur ; Andrew J. O. 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.
