40% higher risk
Analysis of the blood samples showed that women who had an inadequate supply of vitamin D in the first 26 weeks of pregnancy had a 40% higher risk of developing severe pre-eclampsia compared to women with an adequate supply of vitamin D.
However, no association was found between mild preeclampsia and vitamin D deficiency. Dr. Lisa Bodner from the University of Pittsburgh is the lead author of the study published on January 28, 2014 and recommends that if these results are also confirmed with samples of fresh blood, more research should be done in this direction. “Until then,” she adds, “as a consequence of this study, women should take vitamin D supplements on their own initiative.”
