About The Study: In this study of 2,361 mother-child pairs followed up prenatally to child age of approximately two years, prenatal lead exposure was associated with an increased risk of cognitive developmental delay (CDD) in children, especially in those with a high genetic risk. These findings suggest that prenatal lead exposure and genetic background may jointly contribute to an increased risk of CDD for children and indicate the possibility for an integrated strategy to assess CDD risk and improve children's cognitive ability.
