In April, the Interagency Autism Coordinating Committee (IACC), U.S. Department of Health and Human Services, released its top 20 picks for the most significant studies in autism research in 2013. In the top 20 was the study of the prevalence of Autism Spectrum Disorder (ASD) among Somali children, ages 7-9, in Minneapolis conducted by the University of Minnesota’s Institute on Community Integration. The study’s report, “Minneapolis Somali Autism Spectrum Disorder Prevalence Project: Community Report 2013,” summarizes the findings of this study, the largest to date to look at the number and characteristics of Somali children with ASD in any U.S. community.
Funded by the Centers for Disease Control and Prevention, the National Institutes of Health, and Autism Speaks, and managed by the Association of University Centers on Disability, the project reviewed more than 5,000 clinical and educational records of children ages 7-9 in Minneapolis during the 2010 calendar year. The study’s findings include:
- About 1 in 32 Somali children in Minneapolis, ages 7-9 in 2010, was identified as having ASD.
- Minneapolis Somali and White children were about equally likely to be identified with ASD (the prevalence estimate for White children was 1 in 36, with no statistically meaningful difference from the Somali prevalence).
- Somali and White children were more likely to be identified with ASD than Hispanic and non-Somali Black children in the city (the Black non-Somali prevalence was 1 in 62, Hispanic was 1 in 80).
- Somali children with ASD were more likely to also have an intellectual disability (e.g., IQ lower than 70) than children with ASD in all other racial and ethnic groups in Minneapolis, according to the findings.
- The age at first ASD diagnosis was around 5 years for Somali, White, Black, and Hispanic children. Because children with ASD can be reliably diagnosed around 2 years of age, this indicates the need for further research to understand why Minneapolis children with ASD, especially those who also have intellectual disability, are not getting diagnosed earlier.
