When performing developmental screenings in the well-child clinic, the registered nurse understands that which child is at highest risk of developing autism spectrum disorder?

2-year-old who has a vocabulary of 10 words

3-year-old who received measles, mumps, and rubella immunization at age 1 year

5-year-old whose parents were age 42 at the time of birth

4-year-old whose 10-year-old sibling has the disorder

Although the cause of autism spectrum disorder (ASD) is unknown, numerous studies indicate that it has a strong genetic component. The underlying genetic source is unknown in the majority of cases; however, researchers hypothesize that genetic factors predispose to an autism phenotype and that genetic expression is influenced by environmental factors.

(Option 1) A 2-year-old with a vocabulary of a few words only is a concern; however, there are a number of factors and/or conditions that could cause language or overall developmental delay.

(Option 2) There is no scientific evidence that the measles, mumps, and rubella vaccine or thimerosal-containing vaccines (eg, influenza) are linked to ASD.

(Option 4) Retrospective studies have linked parents of older age to autism; however, this association is inconclusive.

Educational objective: There is strong scientific evidence of a genetic component to autism spectrum disorder (ASD). As a result, parents who have a child with ASD are at higher risk of having another child with this disorder. There is no evidence that supports a link between vaccines and ASD, and studies on associations between advanced parental age and the disorder are inconclusive.
