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.

Specifically, the researchers found that each week of gestational age at term was associated with 6 percent lower hyperactivity scores and 5 percent lower ADHD and cognitive problems or inattention scores, and that birth at 37 to 38 weeks was associated with 23 percent higher hyperactivity scores and 17 percent higher ADHD scores when compared with birth at 39 to 41 weeks.
