Among children born at term (37–41 weeks), those born before 39 weeks are more likely to experience symptoms associated with attention-deficit/hyperactivity disorder (ADHD), according to a study by Rutgers Robert Wood Johnson Medical School.

ADHD, which affects more than 10 percent of U.S. school-age children, according to the Centers for Disease Control and Prevention, manifests early in childhood with symptoms of hyperactivity, impulsivity or inattention, and has known links to preterm birth (less than 37 weeks gestation). The study, published in the Journal of Pediatrics, is one of only a few to investigate the associations between gestational age at term (37–41 weeks) and a diagnosis or symptoms of ADHD. It is the first to include reports from teachers.

“Teachers’ reports, in conjunction with maternal reports and physician evaluations, provide valuable input for the diagnosis of ADHD,” said Nancy Reichman, author of the study and a professor of pediatrics at Rutgers Robert Wood Johnson Medical School. To read the full story.
