ABSTRACT
This study examined relations of blood lead < 10 microg/dL, iron, zinc, and parenting to Head Start children's (N = 112) scores on Peabody Picture Vocabulary Test-III (PPVT-III) and McCarthy Scales of Children's Abilities (MSCA). Venous whole blood and plasma samples were analyzed for lead and zinc by ICP-MS and iron status was assessed by serum transferrin receptors. Hierarchical regressions revealed significant effects of lead on MSCA perceptual scores and iron on PPVT-III and MSCA verbal scores. Children with lead > 2.5 microg/dL had significantly lower MSCA perceptual scores than children < 2.5 microg/dL. Permissive parenting significantly exacerbated negative effects of higher lead or lower iron on children's perceptual or verbal scores, respectively.
