RESUMO
Introduction: Maternal vitamin D deficiency is a major publichealth problem. Poor vitamin D status during pregnancy isassociated with poor outcomes and increased morbidity. Thepresent study was conducted to find any association betweenmaternal vitamin D3 deficiency and IUGR and impact ofVitamin D3 supplementation on the outcome.Material and Methods: This prospective, randomised, doubleblind, interventional study was conducted on 172 pregnantwomen diagnosed of Type II/Type III IUGR and confirmedby ultrasound. They were randomly divided into two Groups:Group A (supplemented with Vitamin D 2000 IU/day) andGroup B (no supplementation). All the cases were followedup till delivery and any significant events were recorded.Results: Statistically significant differences were found in thecaesarean section rates and birth weights of the neonate in boththe Groups. There was no significant impact on duration ofgestation. Moderately positive correlation was found betweenthe duration of supplementation and increase in birth weight.Conclusion: Maternal Vitamin D3 deficiency is associatedwith increased risk of operative delivery and low birth weight,both of which can be improved by Vitamin D supplementation.The increase in birth weight correlates with the duration ofsupplementation.
