The article cites a study on the relationship between newborn size and mother's blood cadmium (Cd) levels. The effect of blood Cd, which reflects not only Cd body burden but also recent Cd exposure and communicates with fetal blood in the placenta, on newborn size at birth was investigated. The correlation between maternal blood Cd and infant birth weight also showed an inverse relationship, but it was not significant. On the other hand, the mean birth weight of eight infants whose maternal blood Cd was more than 13.4 nmol/l was 2889 g, and significantly lower than that of infants whose maternal blood Cd was under 13.4 nmol/l. These facts suggest that maternal Cd exposure might affect infant size, which was expressed as either weight or height, but its effect on the infant height is clearer even in lower levels than the exposure level to affect the weight. A larger population including highly exposed women will be necessary to clarify the relationship with birth weight in a future study. In addition, an effect of Cd on bone and calcium metabolism has been reported in adults, but not in the maternal-fetal unit. |
