Maternal Vitamin D Levels During Pregnancy and Their Effects on Maternal-Fetal Outcomes: A Systematic Review.

What It Covers

Researchers studied Vitamin D, K2, Magnesium and Zinc in this systematic review publication.

To synthesize and critically review the current evidence available on maternal vitamin D deficiency and its effects on maternal-fetal outcomes, this study reviewed the maternal-fetal outcomes, including prolonged labour or cesarean delivery, preeclampsia, gestational diabetes, low birth weight and small for gestational age, and preterm birth.

An extensive systematic searched was performed in Medline and EMBASE, where a medical subject heading (MeSH) was used with terms "Vitamin D/25(OH)D" and "pregnancy/fetal outcomes"; these terms were combined with "and." In Web of Science and Google Scholar, a key word search was used.
