Introduction: A deficiency in 25, hydroxy Vitamin D is common throughout the world in both adults and children, being related to skin pigmentation, sun exposure, dietary intake, and obesity. Limited data are available for the neonatal age. This study aims to evaluate the status of Vitamin D in cord blood and the prevalence of its deficiency. Materials and Methods: This is a cross-sectional observational study, conducted in a tertiary neonatal center. Two hundred and sixty-one neonates were enrolled for study after evaluating 311 neonates; the data were tabulated for 255 neonates and evaluated. Results: Nearly, 73% (187) babies had deficient cord Vitamin D levels. One hundred and twenty-five (49%) cord samples were severely deficient (levels were <10 ng/ml). Upper socioeconomic status mothers had better cord Vitamin D levels (17.19 ± 1.91 ng/ml) than the upper middle (14.19 ± 1.00 ng/ml). Normal cord blood Vitamin D levels were associated with better birthweight than deficient (2.99 ± 0.57 vs. 2.80 ± 0.7 kg). Conclusion: Our study showed a high prevalence of Vitamin D deficiency in cord blood. Mothers from higher socioeconomic strata had better cord Vitamin D levels. Birth weight was significantly higher in newborns with normal cord Vitamin D levels.
