Differences in median age at first evaluation noting developmental concern in children with autism spectrum disorder at the deciles and corresponding 95% confidence intervals comparing children of mothers of advanced maternal age to those with mothers not of advanced maternal age, identified by the Autism and Developmental Disabilities Monitoring Network in 2008, 2010, and 2012

Advanced maternal age (AMA) defined as childbirth at ≥35 years of age

Difference is age at first evaluation noting developmental concern for children of AMA mothers – non-AMA mothers

Adjusted model controlled for maternal race/ethnicity, maternal education, study site, child year of birth, child gestational age, paternal age, parity, birth order, and record type with multiple imputation to account for missing paternal age data.
