Racial-ethnic and neighborhood inequities in age of treatment receipt among a national sample of children with autism spectrum disorder

Here, we included 1309 children diagnosed with autism spectrum disorder in the National Survey of Children’s Health, 2011–2012. Controlling for key covariates, we used a weighted generalized logit model to analyze differences in age of treatment receipt (<2 years, 2 years, 3 years, and ⩾4 years).

Compared to non-Hispanic White children, the relative probability (odds) of entering treatment at 3 years and ⩾4 years rather than <2 years was 326% and 367% higher, respectively, for non-Hispanic Black children. Compared to children whose parents perceived their neighborhood to be cohesive, the relative probability of entering treatment at 2 years and 3 years rather than <2 years was 59% and 61% lower, respectively, for children whose parents did not.
