Correlation Between Maternal Vitamin D Level And Preterm Birth

Correlation Between Maternal Vitamin D Level And Preterm Birth

Assessment of correlation between vitamin D level and prevalence of preterm births remains limited. The exact role of vitamin D in preterm birth has not yet been clearly defined ,where some studies showed vitamin D deficiency increased the risk of preterm birth while other studies found no correlation. In this study will try to continue research on this subject.
