Attention-Deficit Hyperactivity Disorder Risk: Interaction Between Parental Age and Maternal History of Attention-Deficit Hyperactivity Disorder

ABSTRACT: Objective: To assess the interaction between maternal attention-deficit/hyperactivity disorder (ADHD) history and young parental age on child's ADHD risk. Methods: The study included 321,272 singleton children born between 1995 and 2012 from hospitals within a single integrated health care organization. The children were prospectively followed up through electronic medical record systems from birth until the first date of the following: date of clinical diagnosis of ADHD, last date of continuous health plan membership, death due to any cause, or December 31, 2017. Risks of ADHD associated with a maternal history of ADHD before pregnancy and young parental age were assessed by using Cox regression adjusting for potential confounders. Results: The children were followed up for a median (interquartile range) of 8.9 (6.2, 13.6) years from birth. Among them, 5.1% had ADHD diagnosis, 1.8% had a maternal history of ADHD before the pregnancy, and 4.4% had mothers
