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=鈭?.28, p=0.01) and Pb (r_s=鈭?.26, p=0.02) concentrations in one case area. Higher estimated Pb concentrations were consistently positively associated with frequency of black mothers (all p<0.02) and negatively associated with frequency of white mothers (all p<0.01), suggesting a racial disparity with respect to Pb.
