Factors affecting the age at diagnosis of autism spectrum disorders in Nova Scotia, Canada / Priscilla FRENETTE in Autism, 17-2 (March 2013)
[article]
Titre : Factors affecting the age at diagnosis of autism spectrum disorders in Nova Scotia, Canada Type de document : Texte imprimé et/ou numérique Auteurs : Priscilla FRENETTE, Auteur ; Linda DODDS, Auteur ; Kathleen MACPHERSON, Auteur ; Gordon FLOWERDEW, Auteur ; Brian HENNEN, Auteur ; Susan E. BRYSON, Auteur Article en page(s) : p.184-195 Mots-clés : autism age of diagnosis ADHD maternal age at delivery Index. décimale : PER Périodiques Résumé : While early diagnosis of autism spectrum disorders (ASD) is essential for ensuring timely access to early intervention services, there is limited existing literature investigating factors that delay this diagnosis. This population-based cohort study explored the age at which children in Nova Scotia, Canada, are diagnosed with ASDs and the factors associated with this age. Children diagnosed with an ASD between January 1992 and December 2005 were identified from a cohort of live births in the province between 1990 and 2002. Demographic and clinical variables were extracted from population-based perinatal and administrative health databases and evaluated as predictors of age at ASD diagnosis. Of 122,759 live births, 884 cases of ASDs were identified during the study period. The median age at diagnosis within the cohort was 4.6 years. In adjusted linear regression analysis, a one year increase in maternal age at delivery was associated with a 0.06 decrease in age at ASD diagnosis (p?=?.0007). Children who were residents of Halifax County received their diagnoses 0.52 years later than residents of other counties (p?=?.0054). A diagnosis of attention-deficit/hyperactivity disorder (ADHD) was associated with a 1.29-year increase in age at diagnosis (p??.0001). These results suggest that potential exists for improving early detection of ASDs in the province. Future research in this field has the potential to contribute to our understanding of the causal pathways linking the demographic and clinical variables we have identified and the age at diagnosis of ASDs.

Titre : The Role of Prenatal, Obstetric and Neonatal Factors in the Development of Autism Type de document : Texte imprimé et/ou numérique Auteurs : Linda DODDS, Auteur ; Deshayne B. FELL, Auteur ; Sarah SHEA, Auteur ; B. Anthony ARMSON, Auteur ; Alexander C. ALLEN, Auteur ; Susan E. BRYSON, Auteur Année de publication : 2011 Article en page(s) : p.891-902 Langues : Anglais (eng) Mots-clés : Autism Cohort Prenatal Pregnancy Neonatal Epidemiology Index. décimale : PER Périodiques Résumé : We conducted a linked database cohort study of infants born between 1990 and 2002 in Nova Scotia, Canada. Diagnoses of autism were identified from administrative databases with relevant diagnostic information to 2005. A factor representing genetic susceptibility was defined as having an affected sibling or a mother with a history of a psychiatric or neurologic condition. Among 129,733 children, there were 924 children with an autism diagnosis. The results suggest that among those with low genetic susceptibility, some maternal and obstetric factors may have an independent role in autism etiology whereas among genetically susceptible children, these factors appear to play a lesser role. The role of pre-pregnancy obesity and excessive weight gain during pregnancy on autism risk require further investigation.
