Attention-deficit/hyperactivity disorder (ADHD) increases the risk of subsequent sexually transmitted infections (STIs) among adolescent and young adult populations by about three times, reports a study published in the January 2018 issue of the Journal of the American Academy of Child and Adolescent Psychiatry (JAACAP). The authors also found that short- and long-term use of ADHD medication reduced the risk of subsequent STIs among men by 30% and 41%, respectively.
