| Résumé : |
In this chapter, we discuss methodological factors which impact the estimation of prevalence of autism spectrum disorders (ASD), and how current trends in prevalence change are being interpreted. Our systematic literature review results in prevalence estimates ranging from 0.063% to 2.6% for ASD, with the best current estimate of prevalence being approximately (74/10,000). Males are affected four to five times more often than females. In addition, a smaller proportion of children diagnosed with an autistic disorder (~32%) compared to that of all ASD children combined (~53%) have normal cognitive functioning. Rate trends analyses confirm an increase in ASD prevalence, and that the possibility of a true increase in incidence should not be ruled out. Explanations for an increase of ASD within and across populations are considered. However, increasing trends in prevalence rates cannot be directly attributed to an increase in the incidence of ASD, due to multiple confounding factors. |
