To find the association between Vitamin D deficiency and GDM.
Methods: Prospective study included 50 women with GDM and 50 normoglycemic pregnant women. Serum Vitamin D level was estimated and correlation between low Vitamin D level and GDM was analysed statistically.
Results: Prevalence of Vitamin D deficiency was 56%.Vitamin D was not significantly decreased in GDM group. Obesity, advancing age were significant risk factors for GDM (p<0.05).Parity, bad obstetric history and weight of baby were comparable in both groups. 34(68%) GDM women needed insulin for glycemic control. 4 GDM women on insulin developed preeclampsia. Baby weighing >3.5Kg was significantly higher in women treated with insulin.
Conclusion: High prevalence of Vitamin D deficiency in pregnancy is not associated with the risk of GDM. Further trials are needed to document Vitamin D deficiency as risk factor for the occurrence of GDM.
