摘要

We undertook a community-level aggregate analysis in South Carolina, USA, to examine associations between mother-child conditions from a Medicaid cohort of pregnant women and their children using spatially interpolated arsenic (As) and lead (Pb) concentrations in three geographic case areas and a control area. Weeks of gestation at birth was significantly negatively correlated with higher estimated As (r s=-0.28, p=0.01) and Pb (r s=-0.26, p=0.02) concentrations in one case area. Higher estimated Pb concentrations were consistently positively associated with frequency of black mothers (all p0.02) and negatively associated with frequency of white mothers (all p0.01), suggesting a racial disparity with respect to Pb.
