To examine whether parental ages at birth of children with pervasive developmental disorders (PDD) are elevated, maternal/paternal ages at birth of 309 PDD children born in 1993-2003 (mean age, 8.4 years) were compared with those of children in the Japanese national statistics (general population). The mean maternal/paternal ages (years) at birth of PDD children of 31.7/34.6 were significantly higher even than the highest mean maternal/paternal ages at birth of children of 31.2/33.6 in the national statistics in 2003. This first Japanese study to report elevated parental ages at birth of PDD children underscores the need of further extensive studies.
