Conclusion
Contradicting previously published results, we found that the level of 25(OH)D was highest in cord blood. A low maternal level did not obstruct the transport over the placenta. Also, the odds for premature delivery, premature rupture of membranes, low AS, or diabetes were not increased with 25(OH)D levels <50nmol/L. Considering that 47% of mothers were deficient, the study highlights the need for a standardized guideline for screening, treating, and following up pregnant women, especially in high-risk areas.
