Under-detection of autism among First Nations children in British Columbia, Canada.

This article shows that First Nations children diagnosed with autism in British Columbia, Canada are under-represented in publications regarding autism and the prevalence thereof, and that this group appears to be under-detected. The aim of this review of publications regarding autism and aboriginal populations in Canada and other countries is to examine possible explanations. The research review results suggest that possible reasons for under-detection of autism among aboriginal populations, and consequently First Nations peoples, can be diagnostic substitution and symptom presentation, ethnic or cultural, area of residence or the impact of historical oppression and discrimination.
