Vitamin D deficiency may increase risk of preeclampsia

According to a new US study women with low vitamin D levels in the first 26 weeks of their pregnancy may be at risk of developing severe preeclampsia, posing a high health risk to the mother and child.

The observational study analyzed blood vitamin D concentrations of 700 pregnant women who later deve- loped preeclampsia and of 3,000 mothers who did not develop a complication during pregnancy (1). The study results showed that a sufficient vitamin D level was associated with a 40% reduction in risk of severe (but not mild) preeclampsia.

The researchers commented that vitamin D has diverse functions in the body beyond maintaining bone and muscle health, including actions that may be important for maintaining a healthy pregnancy. Further explo- ring the role of vitamin D in reducing the risk of preeclampsia is warranted. Severe and mild preeclampsia are thought to have different root causes. Preeclampsia is a condition characterized by high blood pressure and significant amounts of protein in the urine of a pregnant woman.
