Early signs of autism are hard to detect; Latino children diagnosed less often, later

Autism Spectrum Disorders, or ASDs, are a type of developmental disability that begins in early childhood. ASDs are relatively common, affecting as many as one in 50 children.

As pediatricians, we know that identifying children with ASDs early in life is important. The treatment for autism is behavioral therapy, and the sooner that children with ASD starts therapy, the better their functioning will be later in life.

Early diagnosis is important, but the early signs of autism are difficult to detect, both for parents and for pediatricians. Your doctor might be concerned for ASD if your child:

  • Doesn’t take an interest in other people.
  • Doesn’t respond to his/her name or seems like he/she doesn’t hear.
  • Doesn’t point with his/her index finger, or look at things when you point at them.
  • Doesn’t bring you toys or other objects to show you.
  • Plays with objects or toys in an unusual way.
  • Has an unusually difficult time tolerating changes in his/her schedule or routine.

Because these signs can be subtle, the American Academy of Pediatrics (AAP) recommends that pediatricians screen for ASD at 18- and 24-month well-child checks using a standardized checklist. In addition, the AAP recommends that pediatricians screen for general developmental delays at the 9-, 18- and 24-month well-child checks. These tests help pediatricians better identify which children are in need of further ASD evaluation.

My research team is interested in finding out how many pediatricians are performing these important tests. We especially wanted to find out if they were offering tests to families who are at high-risk for delayed ASD diagnosis. Several studies show that Latino families are diagnosed with ASD much later than other families, and we wondered if one of the reasons might be that pediatricians were not offering ASD screening tests in Spanish.

We recently completed a survey of more than 250 primary care pediatricians in California, asking them about what kind of screening they were offering for children at risk for ASD. We found that:

  • Only 15 percent of primary care pediatricians were offering the recommended screening tests, and that only 10 percent were offering these tests in Spanish.
  • Even pediatricians who had more than 25 percent Latino patients in their practice were unlikely to offer screening tests in Spanish (only 13 percent had them).
  • Most pediatricians felt that ASD identification was much more difficult in Spanish-speaking families than in English-speaking families.

The study, which was recently published in the journal Pediatrics, suggests that pediatricians still have a lot of room for improvement in early ASD identification. They may especially need more support in identifying ASD among children whose families speak other languages.

Giving pediatricians better access to bilingual screening tools would probably help them identify Latino children earlier.   

If you as a parent have a concern about your child’s development, it is very important to discuss it with your pediatrician. Parents can help pediatricians do their jobs better by coming to them early with their concerns.

Doctors will be more likely to start screening for ASD if parents let them know it is important.
