Maternal stress modifies the effect of exposure to lead during pregnancy and 24-month old children's neurodevelopment

摘要

Background: Lead and psychosocial stress disrupt similar but not completely overlapping mechanisms. Exposure during the prenatal period to each of these insults singularly has been found to alter normal neurodevelopment; however, longitudinal associations with stress modifying the effect of lead have not been sufficiently analyzed in epidemiologic studies.
