Prenatal fluoride exposure and attention deficit hyperactivity disorder (ADHD)

  • Prenatal fluoride exposure and attention deficit hyperactivity disorder (ADHD) symptoms in children at 6–12 years of age in Mexico City
  • We measured urinary fluoride in 213 pregnant women living in Mexico City who were part of the ELEMENT pregnancy cohort study.
  • Higher concentration of maternal urinary fluoride was associated with more ADHD-like symptoms in school-age children.
  • Prenatal exposure to fluoride was most strongly associated with behavioral ratings of inattention, but not hyperactivity and impulse control.
