Abstract: 

Pregnancy is a time of increased need for supplementations like calcium. This theory was already supported that maternal calcium supplements during pregnancy was found to bring about a remarkable increase in the density of all the bones in the neonates; this suggests the fact that increased calcium had been actively transferred to the fetus via the placenta (1). In recent years, use of calcium supplements during pregnancy, especially in the last trimester have been recommended to prevent disadvantages of calcium loss by mother and also providing sufficient calcium supplement for the fetus (2, 3). There is a theoretical concern that the excessive consumption of calcium supplements may induce hypocalcaemia in the fetus and neonate, that can be a cause of hypercalciuria, which may be followed by urinary calculi and nephrocalcinosis (4). Recently, we experienced noticeable incidence of hypercalciuria, nephrolithiasis and nephrocalcinosis in healthy newborns. In the present study we investigated the influence of mother’s calcium supplementation in generating hypocalcaemia and hypercalciuria in neonates that were born in hospitals of Yasuj University of medical sciences (south-west of Iran).
