Medscape (12/3, Brooks) reports that according to a study published online Dec. 2 in the journal Pediatrics, “low birth weight, post-term pregnancy, low Apgar scores, and fetal distress were not factors for” attention-deficit/hyperactivity disorder (AD/HD), “irrespective of sex.” Researchers arrived at that conclusion after studying data on 12,291 kids and teens with AD/HD and 30,071 youngsters without AD/HD who served as controls. The study did reveal, however, “an elevated risk for AD/HD in both boys and girls when mothers had a urinary tract infection during pregnancy…or preeclampsia.”
