Relationship between maternal vitamin D status and preterm birth
In an urban medical center treating a large and diverse population of women, a clear association between maternal vitamin D blood concentration and risk of preterm birth (< 37 gestational weeks) was demonstrated. Lower risk of preterm birth was noted among mothers with higher vitamin D concentration (≥ 40 ng/ml).
