OBJECTIVES:
To update UK studies begun in the early 1990s on the annual prevalence and incidence rates of autism in children; undertaken in response to a March 2012 press release, widely covered by the media, from the US Centre for Disease Control (CDC) reporting that the autism prevalence rate in 2008 in 8-year-old US children was 1 in 88, a 78% increase from a CDC estimate in 2004. This finding suggested a continuation of the dramatic increase in children diagnosed as autistic, which occurred in the 1990s.DESIGN:
Population study using the UK General Practice Research Database (GPRD).METHODS:
Annual autism prevalence rates were estimated for children aged 8 years in 2004-2010 by dividing the number diagnosed as autistic in each or any previous year by the number of children active in the study population that year. We also calculated annual incidence rates for children aged 2-8 years, by dividing the number newly diagnosed in 2004-2010 by the same denominators.RESULTS:
Annual prevalence rates for each year were steady at approximately 3.8/1000 boys and 0.8/1000 girls. Annual incidence rates each year were also steady at about 1.2/1000 boys and 0.2/1000 girls.CONCLUSIONS:
Après une augmentation de cinq fois du taux d'incidence annuel de l'autisme dans les années 1990 au Royaume-Uni, les taux d'incidence et de prévalence chez les enfants de 8 ans,ont atteint un plateau au début des années 2000 et sont resté stables jusqu'en 2010.
Que les taux de prévalence aient augmenté par rapport au début des années 2000 aux Etats-Unis reste incertain.
