Coffee During Pregnancy Not Linked with Childhood Hyperactivity

Participants in the study (3,400 mothers) were asked how much coffee they consumed during pregnancy. When their children turned 5 or 6, the same women filled out questionnaires about their kids' behavioral health -– teachers completed an identical survey. The authors concluded that mothers who drank caffeine during pregnancy did not put their kids at risk for "hyperactivity/inattention problems, emotional symptoms, conduct problems, peer relationship problems, overall problem behavior, or suboptimal prosocial behavior."
