Early diagnosis of autism spectrum disorder is challenging due to its phenotypic and etiological heterogeneity, but critical for implementation of early interventions. We examined the age of autism spectrum disorder diagnosis in a sample of 554 children and adolescents enrolled in the ELENA cohort study in France with regard to the influences of…

Lodi-Smith, Jennifer; Rodgers, Jonathan D.; Cunningham, Sara A.; Lopata, Christopher; Thomeer, Marcus L. – Autism: The International Journal of Research and Practice, 2019
The present meta-analysis synthesizes the emerging literature on the relationship of Big Five personality traits to autism spectrum disorder. Studies were included if they (1) either (a) measured autism spectrum disorder characteristics using a metric that yielded a single score quantification of the magnitude of autism spectrum disorder…

Several studies have suggested an association between vitamin D in childhood and autism spectrum disorder. No prospective studies have evaluated whether lower vitamin D levels precede ASD diagnoses -- a necessary condition for causality. The objective of this study was to prospectively evaluate whether vitamin D serum levels in early childhood was…

Lung, For-Wey; Chiang, Tung-Liang; Lin, Shio-Jean; Lee, Meng-Chih; Shu, Bih-Ching – Autism: The International Journal of Research and Practice, 2018
The use of assisted reproduction technology has increased over the last two decades. Autism spectrum disorders and assisted reproduction technology share many risk factors. However, previous studies on the association between autism spectrum disorders and assisted reproduction technology have shown inconsistent results. The purpose of this study…

Longitudinal Relations between Autistic-Like Features and Functional Somatic Symptoms in Adolescence
Hogendoorn, Elske; Hartman, Catharina A.; Burke, Sarah M.; van Dijk, Marijn W. G.; Rosmalen, Judith G. M. – Autism: The International Journal of Research and Practice, 2023
Autistic-like features and functional somatic symptoms (FSS) frequently co-occur. It remains unknown how autistic-like features and FSS affect each other and develop throughout adolescence. This study examined reciprocal relations between autistic-like features and FSS in adolescence. Participants were 2772 adolescents (52.5% male) from the…

Stacy, Maria E.; Zablotsky, Benjamin; Yarger, Heather A.; Zimmerman, Andrew; Makia, Barraw; Lee, Li-Ching – Autism: The International Journal of Research and Practice, 2014
This study investigated differences in co-occurring diagnoses made in females compared to males with autism spectrum disorders in 913 children (746 males and 167 females) living in the United States with a current autism spectrum disorder diagnosis identified via caregiver-reported data from the National Survey of Children's Health 2007. The…

Schott, Whitney; Tao, Sha; Shea, Lindsay – Autism: The International Journal of Research and Practice, 2022
Adults on the autism spectrum and those with intellectual disability or mental health conditions may be at increased risk of contracting COVID-19 or experiencing more severe illness if infected. We identified risk factors for COVID-19 among adults enrolled in Medicaid with an autism spectrum disorder diagnosis, intellectual disability, or mental…

MacKenzie, Kristen T.; Mazefsky, Carla A.; Eack, Shaun M. – Journal of Autism and Developmental Disorders, 2023
Obtaining an autism spectrum disorder (ASD) diagnosis is often challenging for parents. The purpose of this study was to better understand this process and examine how elements of the process may influence parent satisfaction. A total of 406 parents of autistic children participated. Participants were administered a survey covering the ASD…

Frazier, Thomas W.; Youngstrom, Eric A.; Embacher, Rebecca; Hardan, Antonio Y.; Constantino, John N.; Law, Paul; Findling, Robert L.; Eng, Charis – Autism: The International Journal of Research and Practice, 2014
Demographic and clinical factors may influence assessment of autism symptoms. This study evaluated these correlates and also examined whether social communication and interaction and restricted/repetitive behavior provided unique prediction of autism spectrum disorder diagnosis. We analyzed data from 7352 siblings included in the Interactive…

We examined associations between child body mass index at 2-5 years and maternal pre-pregnancy body mass index, gestational weight gain, and rapid weight gain during infancy in children with autism spectrum disorder, developmental delays, or population controls. The Study to Explore Early Development is a multi-site case-control study of children,…

Montiel-Nava, Cecilia; Chacín, José A.; González-Ávila, Zoila – Autism: The International Journal of Research and Practice, 2017
Latino children are diagnosed with autism spectrum disorder later in life, usually with more severe symptoms, and lower IQs, compared with non-Latino children. Possible reasons for such disparities could be due to lower levels of parent education, lower socioeconomic status, limited knowledge of parents about autism spectrum disorder, and…

Objective: To evaluate whether early folic acid supplementation during pregnancy prevents diagnosis of autism spectrum disorders in offspring. Methods: Information on autism spectrum disorder diagnosis was obtained from the National Hospital Register and the Central Psychiatric Register. We estimated risk ratios for autism spectrum disorders for…

Mastrogiuseppe, Marilina; Capirci, Olga; Cuva, Simone; Venuti, Paola – Autism: The International Journal of Research and Practice, 2015
Children with autism spectrum disorders display atypical development of gesture production, and gesture impairment is one of the determining factors of autism spectrum disorder diagnosis. Despite the obvious importance of this issue for children with autism spectrum disorder, the literature on gestures in autism is scarce and contradictory. The…
