Objectives: We sought to examine differences in caregiver-reported adverse childhood experiences (ACEs) in adolescents with and without autism and explore associations between ACEs and behavioral and emotional problems in those with ACEs.
Methods: Children were classified as having autism, another developmental disability (DD), or population comparison (POP) after a comprehensive evaluation in the Study to Explore Early Development (SEED) between 2 to 5 years of age. Caregivers of these same children completed the SEED Teen survey and answered questions about ACEs and current behavioral and emotional problems at 12 to 16 years of age.
Prenatal alcohol exposure has been linked to adverse neurodevelopmental outcomes. However, its effects on developmental outcomes in children with autism spectrum disorder (ASD) remain unclear. We examined associations between prenatal alcohol exposure during the first trimester (PAE-FT) and early learning ability, behavioral problems, and severity of autistic traits in preschool-aged children in a large multi-site case-control study, the Study to Explore Early Development.

Few studies explore activities related to depressive symptoms in autistic people and those with other DD during adolescence.
Objective: The objectives of this analysis were to describe depressive symptoms and activity engagement among autistic adolescents and those with other DD and no DD and explore types of activities associated with depressive symptoms, stratified by study group.
Objective: To test initial hypotheses that the coronavirus disease 2019 (COVID-19) pandemic was associated with decreases in adaptive behavior and increases in behavioral and emotional problems of children with autism; greater impacts for children who lost specialty services; and greater behavioral and emotional problems for children with autism vs control participants.
Method: Eligible participants (N = 1,158) enrolled in phase 3 of the multisite, case-control Study to Explore Early Development (SEED) before March 31, 2020, were between 2 and 5 years old, and completed follow-up assessments between January and July 2021. Caregivers completed a COVID-19 Impact Assessment Questionnaire, Vineland Adaptive Behavior Scales (VABS), and Child Behavior Checklist (CBCL) for 274 children with autism and 385 control participants.
Objective: Many children with autism spectrum disorder (ASD) and other developmental disabilities (DD) transitioned to telehealth services due to the COVID-19 pandemic. Our objectives were to describe reductions in allied and behavioral healthcare services and receipt of caregiver training to deliver services at home because of COVID-19 for children with ASD and other DD, and factors associated with worse response to remote delivery of services for children with ASD.
Method: Prior to the pandemic, children 2 to 5 years of age were enrolled in a multi-site case-control study and completed a developmental assessment.
Background: To control the spread of the coronavirus disease (COVID-19), many jurisdictions throughout the world enacted public health measures that had vast socio-economic implications. In emergency situations, families of children with developmental disabilities (DDs), including autism, may experience increased difficulty accessing therapies, economic hardship, and caregiver stress, with the potential to exacerbate autism symptoms. Yet, limited research exists on the economic impacts of the COVID-19 pandemic on families of children with autism or another DD compared to families of children from the general population.

Although diagnostic criteria for ID require impairments in both cognitive and adaptive functioning, most population-based estimates of the frequency of co-occurring ID in children with autism-including studies of racial and ethnic disparities in co-occurring autism and ID-base the definition of ID solely on cognitive scores. The goal of this analysis was to examine the effect of including both cognitive and adaptive behavior criteria on estimates of co-occurring ID in a well-characterized sample of 2- to 5-year-old children with autism.

We compared children with autism spectrum disorder (ASD) with those with another developmental disability (DD) and from the general population (POP) regarding (1) missed or delayed appointments for regular health/dental services, immunizations, and specialty services; (2) reasons for difficulty accessing care; and (3) use of remote learning and school supports.
Method: Caregivers of children previously enrolled in the Study to Explore Early Development, a case-control study of children with ASD implemented during 2017 to 2020, were recontacted during January-June 2021 to learn about services during March-December 2020.
Sensory dysfunction is a common feature of autism spectrum disorder (ASD). The objectives of this analysis were to examine risk factors and clinical correlates of sensory dysfunction in preschool children with and without ASD. Children aged 2-5 years were enrolled in a multi-site case-control study.

The Human Phenotype Ontology (HPO) is a widely used resource that comprehensively organizes and defines the phenotypic features of human disease, enabling computational inference and supporting genomic and phenotypic analyses through semantic similarity and machine learning algorithms. The HPO has widespread applications in clinical diagnostics and translational research, including genomic diagnostics, gene-disease discovery, and cohort analytics. In recent years, groups around the world have developed translations of the HPO from English to other languages, and the HPO browser has been internationalized, allowing users to view HPO term labels and in many cases synonyms and definitions in ten languages in addition to English.

These terms are common in publications and in everyday communication. However, recent research and feedback from the autistic community suggests that relying on cognitive ability alone to describe functioning may miss meaningful differences in the abilities of autistic children and adults and in the kinds of support they may need.

Increasing evidence exists for an association between early life fine particulate matter (PM) exposure and several neurodevelopmental outcomes, including autism spectrum disorder (ASD); however, the association between PM and adaptive and cognitive function remains poorly understood. Participants included 658 children with ASD, 771 with a non-ASD developmental disorder, and 849 population controls from the Study to Explore Early Development. Adaptive functioning was assessed in ASD cases using the Vineland Adaptive Behavior Scales (VABS); cognitive functioning was assessed in all groups using the Mullen Scales of Early Learning (MSEL).

We sought to identify behavioral and developmental features that best define the heterogeneity and homogeneity in 2-5-year-old children classified with ASD and subthreshold ASD characteristics. Children were enrolled in a multisite case-control study of ASD.
View Article and Find Full Text PDFPersons identified in early childhood as having autism spectrum disorder (autism) often have co-occurring health problems that extend into adolescence (1-3). Although only limited data exist on their health and use of health care services as they transition to adolescence, emerging data suggest that a minority of these persons receive recommended guidance* from their primary care providers (PCPs) starting at age 12 years to ensure a planned transition from pediatric to adult health care (4,5). To address this gap in data, researchers analyzed preliminary data from a follow-up survey of parents and guardians of adolescents aged 12-16 years who previously participated in the Study to Explore Early Development (https://www.
