(SACRAMENTO, Calif.) Hispanic children often have undiagnosed developmental delays and large numbers of both Hispanic and non-Hispanic children who first were thought to have developmental delay actually had autism, researchers affiliated with the UC Davis MIND Institute have found.
The study, one of the largest to date to compare development in Hispanic and non-Hispanic children, is published in the journal Autism. The results lead the study authors to recommend increased public health efforts to improve awareness, especially among Hispanics, about the indicators of developmental delay and autism.
"Our study raises concerns about access to accurate, culturally relevant information regarding developmental milestones and the importance of early detection and treatment," said Virginia Chaidez, the lead author and a postdoctoral researcher in the UC Davis Department of Public Health Sciences when the study was conducted. "Autism and developmental delay tend to go undiagnosed when parents are not aware of the signs to look for, and the conditions are often misdiagnosed when parents don't have access to adequate developmental surveillance and screening."
Developmental delay is diagnosed in children who lag behind others in reaching important mental or physical milestones, while autism is characterized by deficits in social interactions and communication behaviors. The symptoms of both disorders can be improved with targeted interventions, with the greatest improvements seen when interventions begin early in life.
In conducting the study, the researchers used data from the Childhood Autism Risk from Genetics and the Environment (CHARGE) Study, a population-based study of factors that increase risk for autism or developmental delay. The current study included 1,061 children living in California who were between 24 and 60 months of age. They we
