ABSTRACTBackground: Previous studies revealed that maternal serum level of vitamin D can influence neonatal outcomes. In this controlled trial, we evaluated the effect of vitamin D supplementation during pregnancy on birth weight.Methods: In this interventional study, we enrolled 67 pregnant women (gestation: 10 weeks), who referred to Seyyedal Shohada Hospital during two years (from January 2014) with vitamin D less than 30 ng/ml. From gestational age of 14-24 weeks, vitamin D (50,000 IU/week) was administered to the patients, and its level was measured again in the 24th week of gestation. At this time, patients with vitamin D more than 30 ng/ml served as the intervention group, while the remaining patients were excluded (n=55 patients). In the control group, the level of vitamin D was measured at the time of delivery.Results: The mean vitamin D level in the intervention group was 43.04±20.09 ng/ml. The baseline patient characteristics such as gravidity, parity, and the number of deliveries were not significantly different between the two groups. However, the two groups were significantly different regarding neonates� characteristics such as birth weight, height, and headcircumference.Conclusion: Our findings showed that administrating vitamin D during pregnancy increases the mean values of neonatal weight, head circumference, and height.
