Autism Prevalence Up, But Racial Gap Closing?

The prevalence of autism spectrum disorder (ASD) among children aged 8 years in the US was 18.5 per 1,000 in 2016, higher than previous estimates. While no overall difference in prevalence was found between Black and White children, disparities persist in early evaluation and diagnosis for Black children, and Hispanic children continue to be identified less frequently.

Scientists found that more kids have autism than we thought before. They also learned that some kids, especially Black and Hispanic children, might not be getting diagnosed as quickly or as often.

Posibles conflictos de intereses

One author, Zachary Warren, reported receiving personal fees and grants from various pharmaceutical and technology companies, though these were unrelated to the submitted work. Another author, John Constantino, reported receiving a grant from Western Psychological Services, also outside the submitted work.

Limitaciones identificadas

Reliance on Existing Records
The reliance on existing records for case ascertainment can lead to underestimation if records are incomplete or inaccessible, especially for specific demographic groups like Black or Hispanic children who might primarily receive services at school.
Record Completeness
Incomplete records can also affect the accuracy of documenting the age of first diagnosis and IQ testing, further impacting the study's findings.
Non-Representative Sample
The ADDM Network sites are not nationally representative due to the competitive funding process, limiting the generalizability of the prevalence estimates to the entire US population.
Changing Geographic Coverage
Changes in the ADDM Network's geographic coverage over time make it challenging to interpret temporal trends and compare prevalence across different surveillance years.

Explicación de la calificación

This is a robust study utilizing a well-established surveillance program with a clearly defined methodology. Despite some limitations regarding data collection and generalizability, the findings provide valuable insights into ASD prevalence and disparities. The identified conflicts of interest appear to be minimal and unrelated to the study itself.
