Mercury Exposure and Atopic Dermatitis in Early Childhood

There is an increased risk of atopic dermatitis (AD) in children following postnatal mercury exposure at 24 months of age, a new study found. A total of 1,751 pregnant women were enrolled in Mothers and Children’s Environmental Health cohort study. After delivery, children were followed up, blood samples were collected, and mothers were asked about the presence of AD in their children via a questionnaire at 6, 12, 24, 36, and 60 months of age. Among the details:

  • A total of 1,061 mother-children pairs who met study criteria were included.
  • The geometric mean of mercury concentrations in cord blood was 5.1 µg/L.
  • In adjusted models, cord blood mercury exposure and postnatal mercury exposure were associated with the presence of AD in children.
