Objective To investigate bone nutritional status of neonates and their mothers as well as the correlation between them by estimating the concentrations of 25-D3, calcium and phosphorus in maternal blood and cord blood at birth, and by measuring the bone speed of sound of neonates and their mothers with quantitative ultrasound within 3 days after birth. Methods The concentrations of 25-D3, calcium and phosphorus in the serum were estimated both from 32 pregnant women who had a term delivery and from the umbilical cord at birth.
