Certain demographic characteristics, such as being female or a racially or ethnically minoritized youth, have been associated with significant diagnostic lag. However, it remains unclear how assigned sex, race, and ethnicity interact with each other in predicting the prevalence and age of autism diagnosis.<h4>Methods</h4>To examine the interactions between assigned sex, race, and ethnicity, we used data from the National Survey of Children's Health (NSCH; 2016 > 2021).<h4>Results</h4>One in 38 children had an autism diagnosis and 3.8 males were diagnosed per 1 female. Hierarchical linear regressions yielded diagnostic delays in some femJournal of autism and developmental disordersAutism Prevalence and the Intersectionality of Assigned Sex at Birth, Race, and Ethnicity on Age of Diagnosis.PMC10869641UL1TR001111UL1 TR0011112T32 HD040127-21F31 ES034256KL2 TR002490T32 HD040127T32 HD091058P50 HD103573Goldblum JEPutnam OCBristol SHarrop CMcFayden TCWylie AfalseAutism Prevalence and the Intersectionality of Assigned Sex at Birth, Race, and Ethnicity on Age of Diagnosis.<h4>Purpose</h4>An official autism diagnosis is required to access timely intervention and is associated with better long-term wellbeing and mental health.
