Some variation can be explained by diagnostic methods, case ascertainment and age at diagnosis. This study compared prevalence statistics for two distinct geographical regions, Denmark and Western Australia, both of which have had population-based registers and consistent classification systems operating over the past decade. Overall ASD prevalence rates were higher in Denmark (68.5 per 10,000 children) compared with Western Australia (51.0 per 10,000 children), while the diagnosis of childhood autism was more prevalent in Western Australia (39.3 per 10,000 children) compared with Denmark (21.8 per 10,000 children). These differences are probably caused by local phenomena affecting case ascertainment but influence from biological or geographical factors may exist.

Unpacking the complex nature of the autism epidemic / Helen LEONARD in Research in Autism Spectrum Disorders, 4-4 (October-December 2010)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 4-4 (October-December 2010) . - p.548-554 Titre : Unpacking the complex nature of the autism epidemic Type de document : Texte imprimé et/ou numérique Auteurs : Helen LEONARD, Auteur ; Andrew J. O. WHITEHOUSE, Auteur ; Glenys DIXON, Auteur ; Jenny BOURKE, Auteur ; Karina AIBERTI, Auteur ; Natasha NASSAR, Auteur ; Carol BOWER, Auteur ; Emma J. GLASSON, Auteur Année de publication : 2010 Article en page(s) : p.548-554 Langues : Anglais (eng) Mots-clés : Autistic-disorder Autism Autism-spectrum-disorder Diagnosis Intellectual-disability Autism-epidemic Index. décimale : PER Périodiques Résumé : The etiology of autism spectrum disorders is unknown but there are claims of increasing prevalence in many countries. Despite more than a decade of epidemiological investigation, it is still unclear whether the rising trend in prevalence reflects a true increase or changes in diagnostic trends and improvements in case ascertainment. This paper discusses changes in diagnostic criteria, decreasing age at diagnosis, improved case ascertainment, diagnostic substitution, and social and cultural influences on the overall effects on prevalence, including the role of an ASD diagnosis as a gateway to funding. The evidence suggests that the increased prevalence of autism spectrum disorder can be partly supported by each of these factors, but remains largely unquantified due to a variety of other global and local factors. The question of how much of a real increase in prevalence has occurred remains crucially important to understand the classification, epidemiology and etiology of autism spectrum disorders but can only be answered if controlling these other factors.
