Investigating the relationship between average age of mothers at childbirth and Autism Prevalence Rates (Birth Years 1992–2014) in the United States.

This study examines the relationship between the average age of mothers at childbirth and Autism Spectrum Disorder (ASD) prevalence in children born in the United States between 1992 and 2014. Updated analyses reveal a statistically significant, very strong positive correlation (Correlation coefficient (r): 0.969, p-value: 2.05 × 10⁻⁷) between the average age of mothers at childbirth and Autism Prevalence Rates. A linear regression model further suggests that 94% of the variation in autism prevalence is explained by changes in maternal age. These findings emphasize the need for broader exploration of the impact of delaying childbirth on Autism Prevalence Rates.
