Paternal age increases the risk for autism in an Iranian population sample / Roksana SASANFAR in Molecular Autism, (February 2010)

Titre : Paternal age increases the risk for autism in an Iranian population sample Type de document : Texte imprimé et/ou numérique Auteurs : Roksana SASANFAR, Auteur ; Stephen A. HADDAD, Auteur ; Ala TOLOUEI, Auteur ; Majid GHADAMI, Auteur ; Dongmei YU, Auteur ; Susan L. SANTANGELO, Auteur Année de publication : 2010 Article en page(s) : 10 p. Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Background
Autism is a neurodevelopmental disorder which is known to have a strong genetic component and is most likely oligogenic. However, the necessary role of environmental factors has been well documented. Prior research suggests that parental characteristics, such as age and level of education, may be associated with a risk of autism. Parental age has been shown to be associated with many disorders, such as schizophrenia, childhood cancer and fetal death. However, results from studies of parental age and autism are inconsistent.
Methods
In the present study, we investigated the association of autism with parental age in 179 autism cases and 1611 matched cohort children from Iran. Each case was matched with nine cohort controls on parental education, sex, order of birth, consanguineous marriage, urbanism and province of residence. The Cox regression model was used to carry out conditional logistic regression on the matched data.
Results
There was a significant association between higher paternal age, but not maternal age, and an increasing risk of autism. An analysis of the combined effect of parental age and education also revealed that parents with higher education had an increased risk of having autistic children, with a dose-response effect of parental age.
Conclusions
This study, which is the first epidemiological study of autism in Iran, provides evidence of the association of paternal age and risk of autism.En ligne : http://dx.doi.org/10.1186/2040-2392-1-2 Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=102
