The study highlights that autism spectrum disorder (ASD) is 3.4 times more prevalent among boys, with a rate of 49.2 per 1,000 compared to 14.3 per 1,000 for girls.

A new report from the CDC reveals that the autism diagnosis rate among U.S. children has increased to 1 in 31 by age 8 in 2022, up from 1 in 36 in 2020.

Variability in autism prevalence may reflect differences in screening practices, diagnostic protocols, and access to services across various regions.

Kennedy's statements regarding the autism statistics have drawn attention to the ongoing debate over vaccine safety and the need for further research into autism causes.

The CDC's study, which utilized data from 16 monitoring sites across 14 states and Puerto Rico, was affected by the COVID-19 pandemic, impacting autism evaluations and diagnoses.

Extensive research has ruled out childhood vaccines as a cause of autism, leading to investigations into genetic factors and environmental exposures.

Health Secretary Robert F. Kennedy Jr. announced a large-scale research initiative aimed at identifying the causes of autism and eliminating potential exposures, although his hiring of David Geier has sparked criticism due to Geier's controversial views on vaccines.

While genetic factors are believed to play a significant role in autism, the reasons behind the increasing diagnosis rates remain complex and not fully understood.

The report indicates that lower neighborhood median household income is associated with higher ASD prevalence in certain areas, suggesting socioeconomic factors may influence identification rates.

Experts argue that the rise in autism diagnoses is primarily due to improved recognition and screening practices rather than an actual increase in cases.

Co-author Walter Zahorodny noted that actual autism rates might be closer to those observed in states with robust screening programs, like California.

The findings underscore the urgent need for enhanced planning and equitable access to diagnostic, treatment, and support services for children with ASD, particularly among historically underserved groups.
