Prevalence of treated autism spectrum disorders in Aruba.

Author information

Child and Adolescent Psychiatry Clinic, Oranjestad, Aruba,


To study autism outside of a narrow range of settings previously studied, and in a particularly distinctive setting in the Caribbean. The aim of the Aruba Autism Project was to determine the prevalence of autism spectrum disorders (ASDs) in birth years 1990-1999 in Aruba. A record review study was conducted; cases were ascertained from children treated at the Child & Adolescent Psychiatry Clinic of Aruba, the first and only child psychiatry service on the island. In these 10 birth years we found a prevalence for autistic disorder (AD) of 1.9 per 1,000 (95% CI 1.2-2.8) and for autism spectrum disorders of 5.3 per 1,000 (95% CI 4.1-6.7). Comparison analysis with a cumulative incidence report from the UK, showed a similar cumulative incidence to age five in Aruba. Prevalence of ASDs in birth years 1990-1999 and cumulative incidence to age five in Aruba are similar to recent reports from the United Kingdom and the United States.
