Many studies have examined the association between parental age and psychiatric illness in the children, including autism and schizophrenia. In a recent case-control study from Finland, the authors identified 10,409 individuals with ADHD born between 1991 and 2005 from nationwide population-based registers. Logistic regression was used to examine the association between parental age and ADHD in the offspring, adjusting for potential confounding factors including parental psychiatric history, maternal socioeconomic status, marital status, maternal smoking during pregnancy, number of previous births, and birth weight.
