Summary:Dichlorodiphenyldichloroethylene (DDE) concentrations in umbilical cord of newborns are estimated. A positive correlation is observed between DDE maternal concentrations with that of the umbilical cord. Bivariate analysis demonstrates that the higher the number of pregnancies, the lower the concentration of DDE in newborns. The mean DDE concentration of newborn sons of first-time mothers is significantly higher than that of newborn sons of multiparous women. It is shown that DDT cord serum concentration at birth is inversely associated with verbal, memory, quantitative, and perceptual-performance skills at age 4 years. It is concluded that maternal factors, namely the antecedent of always having lived in the same region, high socioeconomic index and accumulated breast-feeding, significantly influence serum concentrations of DDE in the umbilical cord.
