Comparing Neighborhoods of Children With Autism Spectrum Disorder in a Medicaid Waiver Program and a State Population, 2007-2015.

Abstract

This study investigated equity in enrollment in a Medicaid waiver program for early intensive behavioral intervention for children with autism spectrum disorder (ASD). State administrative, Medicaid, and U.S. Census data for children enrolled in the waiver program between 2007 and 2015 (N=2,111) were integrated. Multivariate and bivariate analyses were used to compare enrollees' neighborhood demographic characteristics with those of the state's general population, with controls for enrollees' age, sex, and race-ethnicity. Findings indicate that in general, enrollment was equitable. During the years in which there were inequities, children who lived in neighborhoods of privilege were favored. These neighborhoods had higher median incomes, lower poverty levels, and fewer female-headed households and were located in urban areas. As states work to provide equitable treatment to children with ASD and their families, it is important to track potential inequities between children who do and do not enroll in services and to use this information to inform outreach efforts. States may turn to South Carolina for insight on how to ensure equity.
