3-181 - Disparities and Developmental Profiles in Individuals with Autism among Under-represented Minority Populations

Sat, April 8, 2:30 to 4:00pm, Austin Convention Center, Meeting Room 19B

Session Type: Paper Symposium

Integrative Statement

Research shows that significant disparities in race, ethnicity, and socioeconomic status exist when examining phenotypic and genetic factors in ASD. Though recent epidemiological studies show a 90% increase in the number of black, non-Hispanic children identified with an ASD and a 110% increase in Hispanic children identified, disparities still exist (CDC, 2014; 2016). For instance, Black and Hispanic children tend to be diagnosed later than White, non-Hispanic children and have poorer access to healthcare services (e.g., Magana et al., 2012). Black and Hispanic children are also less likely to have a documented ASD compared to White children, and tend to be diagnosed with non-ASD conditions early on (Mandell et al., 2009). White children with ASD are also more likely to have parents with higher education and family incomes (Durkin et al., 2010), in contrast to other disabilities.

This symposium explores how factors including race, ethnicity, socio-economic status, and heritability impact autism. The first paper examines ethnographic disparities related to delays in diagnosis and treatment for African American school-aged children with ASD. The second paper explores racial and socioeconomic differences in cognitive, adaptive, and diagnostic profiles of AA vs. Caucasian school-aged children with ASD. The third paper investigates these profiles in AA and Caucasian toddlers upon initial diagnosis of ASD, and the final paper examines quantitative autistic traits as indices of inherited liability to ASD in Hispanic families. Implications for targeting underserved populations with limited access to quality care services will be discussed.
