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.

Early Signs of Autism in Toddlers: A Follow-Up Study in the Danish National Birth Cohort / Sanne LEMCKE in Journal of Autism and Developmental Disorders, 43-10 (October 2013)

In Danish national registries, 720 children with ASD and 231 children with intellectual disability (ID) were identified. At 6 months, associations between early signs and ASD or ID were found only in few areas. At 18 months social, language, and motor skills were delayed, and suspicion of vision and hearing problems were increased for both groups. Signs distinguishing ASD from ID were unclear, and the positive predictive values regarding ASD were below 10 % for individual predictors and aggregated risk scores.

Maternal Infection Requiring Hospitalization During Pregnancy and Autism Spectrum Disorders / Hjördis Osk ATLADOTTIR in Journal of Autism and Developmental Disorders, 40-12 (December 2010)

PARNER, Auteur Année de publication : 2010 Article en page(s) : p.1423-1430 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Autism  Infection  Influenza  Prenatal infection  Maternal infection Index. décimale : PER Périodiques Résumé : Exposure to prenatal infection has been suggested to cause deficiencies in fetal neurodevelopment. In this study we included all children born in Denmark from 1980, through 2005. Diagnoses of autism spectrum disorders (ASDs) and maternal infection were obtained through nationwide registers. Data was analyzed using Cox proportional hazards regression. No association was found between any maternal infection and diagnosis of ASDs in the child when looking at the total period of pregnancy: adjusted hazard ratio = 1.14 (CI: 0.96–1.34). However, admission to hospital due to maternal viral infection in the first trimester and maternal bacterial infection in the second trimester were found to be associated with diagnosis of ASDs in the offspring, adjusted hazard ratio = 2.98 (CI: 1.29–7.15) and adjusted hazard ratio = 1.42 (CI: 1.08–1.87), respectively. Our results support prior hypotheses concerning early prenatal viral infection increasing the risk of ASDs.

Based on review of abstracted behaviors recorded in case records from child psychiatric hospitals, case status determination was performed using a standardized coding scheme. In 499 children diagnosed with childhood autism in the DPCR, the diagnosis could be confirmed in 469 children (94%). Of the 30 non-confirmed cases, five were classified by the reviewers as non-autistic cases and the remaining 25 cases were either classified with another ASD diagnosis or the specific diagnosis was not possible to determine.
