The data were drawn from the 2009 and 2010 Nationwide Emergency Department Sample. We performed both univariate and multivariate analyses to compare…

Lever, Anne G.; Geurts, Hilde M. – Journal of Autism and Developmental Disorders, 2018
Autism spectrum disorder (ASD) characteristics seem to abate over time, but whether this protracts until late adulthood is largely unknown. We cross-sectionally investigated self- and other-reported ASD characteristics of adults with (ASD: N[subscript max-self] = 237, N[subscript max-other] = 130) and without ASD (COM: N[subscript max-self] = 198,…

Previous studies report associations between conception with assisted reproductive technology (ART) and autism. Whether these associations reflect an ascertainment or biologic effect is undetermined. We assessed diagnosis age and initial autism symptom severity among >30,000 children with autism from a linkage study of California Department of…

C.; Zander, E.; Charman, T. – Journal of Autism and Developmental Disorders, 2018
Research on sex-related differences in Autism Spectrum Disorder (ASD) has been impeded by small samples. We pooled 28 datasets from 18 sites across nine European countries to examine sex differences in the ASD phenotype on the ADI-R (376 females, 1763 males) and ADOS (233 females, 1187 males). On the ADI-R, early childhood restricted and…

Brett, Denise; Warnell, Frances; McConachie, Helen; Parr, Jeremy R. – Journal of Autism and Developmental Disorders, 2016
Clinical initiatives have aimed to reduce the age at ASD diagnosis in the UK. This study investigated whether the median age at diagnosis in childhood has reduced in recent years, and identified the factors associated with earlier diagnosis in the UK. Data on 2,134 children with ASD came from two large family databases. Results showed that the age…

Ting, Victoria; Weiss, Jonathan A. – Journal of Autism and Developmental Disorders, 2017
Children with autism spectrum disorder (ASD) often exhibit emotional problems, which can be associated with emotion regulation (ER) difficulties. Parent co-regulation is often associated with child ER and emotional problems, though little work has been done with reference to youth with ASD. This study investigated the association among parent…

VanderLaan, Doug P.; Leef, Jonathan H.; Wood, Hayley; Hughes, S. Kathleen; Zucker, Kenneth J. – Journal of Autism and Developmental Disorders, 2015
Gender dysphoria (GD) and autism spectrum disorder (ASD) are associated. In 49 GD children (40 natal males), we examined ASD risk factors (i.e., birth weight, parental age, sibling sex ratio) in relation to autistic traits. Data were gathered on autistic traits, birth weight, parents' ages at birth, sibling sex ratio, gender nonconformity, age,…

This study aimed to measure the effects of contact with integrated students with autism spectrum disorders (ASD) on the knowledge, attitudes and empathy of children (n = 224) from grades 4-6. A comparison group of children (n = 251) who had no contact with classmates with ASD was also included. All participants completed self-report instruments.…

Aim of the study was to examine the associations between parental age and autism spectrum disorders (ASD). Data were based on the FIPS-A (Finnish Prenatal Study of Autism and Autism Spectrum Disorders), a case-control study with a total of 4,713 cases with childhood autism (n = 1,132), Asperger's syndrome (n = 1,785) or other pervasive…

Croen, Lisa A.; Grether, Judith K.; Hoogstrate, Jenny; Selvin, Steve – Journal of Autism and Developmental Disorders, 2002
This study investigated associations between selected infant and maternal characteristics and autism risk in 4381 California children with autism. Increased risk factors were observed for males, multiple births, and children born to black mothers. Risk increased as maternal age and maternal education increased. Children of immigrant mothers had…
