Context: Vitamin D deficiency widely prevalent throughout the world. Pregnant women, neonates and infants form most vulnerable groups for vitamin D deficiency.

Objective: 1) To find prevalence of vitamin D deficiency in pregnant women. 2) To evaluate effect of supplementation with cholecalciferol in improving vitamin D levels in pregnant women and evaluate its correlation with feto-maternal outcome.

Design: Randomized control trial from years 2010-2012.

Setting: Tertiary care centre, Delhi, India.

Participants: 180 pregnant women. Study population divided randomly into 2 groups; Group A: non-intervention (60 women) and Group B: intervention (120 women).

Intervention: The intervention group received supplementation of vitamin D in dosages depending upon 25(OH)-D levels.

Main Outcome measures: Risk of maternal complications like Pre-term labour; pre-eclampsia and gestational diabetes associated with Vitamin D deficiency and risk of Low birth weight and poor APGAR score in infants of mothers with Vitamin D deficiency.

Results: Adjusted serum 25(OH)-D concentration was lower in group A as compared to group B (mean 46.11 ± 74.21 nmol/L vs 80 ± 51.53 nmol/L). 44% patients in group A and 20.3% patients in group B developed Pre-term labour/Pre-eclampsia/Gestational Diabetes. New-borns of mothers in group A had lower cord blood levels of 25(OH)-D levels as compared to group B (mean 43.11 ± 81.32 nmol/L vs 56.8 ± 47.52 nmol/L). They also had lower birth weight of mean 2.4 ± 0.38 kg as compared to group B 2.6 ± 0.33 kg.

Conclusions: Vitamin D supplementation reduces risk of maternal comorbidities and helps improve neonatal outcomes.
