Dietary assessment of maternal vitamin D intake and correlation with maternal and neonatal serum vitamin D concentrations at delivery.
Maternal and cord blood 25-hydroxy vitamin D concentrations are positively and significantly correlated. If an easily obtainable maternal dietary history could be used to predict maternal and secondarily cord blood vitamin D status, it would be a useful means of assessing the vitamin D adequacy of the newborn. Therefore, a single assessment of maternal dietary vitamin D intake during the last trimester of pregnancy was correlated with maternal and newborn serum vitamin D concentration. Neither the correlation between maternal dietary history of vitamin D intake and maternal serum 25-hydroxy vitamin D level nor between maternal dietary history and cord blood 25-hydroxy vitamin D level was significant. These data indicate that a single maternal dietary history is an inadequate method of predicting neonatal vitamin status at delivery.
