Background: Now a days, vitamin D deficiency is a silent and neglected global public health issue. Vitamin D status during pregnancy is integral to maternal health, fetal development and optimal neonatal outcomes. Decreased maternal vitamin D level causes decreased Neonatal vitamin D level and birth weight. Objectives: To see the association between Neonatal vitamin D level and birth weight. Methods: This cross-sectional study was conducted at neonatology department in Dhaka Shishu (Children) Hospital from July 2020 to June 2021. All admitted term neonates, aged within 5 days, were taken as cases and venous blood was collected for S. vitamin D level. Data regarding age, sex, birth weight, S. vitamin D status etc. were collected and analyzed by SPSS version-26. Results: Out of 72 cases, male were 39 (53%) and female 35 (47%). Mean gestational age was 38.9±1.12 wks. Mean birth weight was 2607.4±420.5 gms. Neonates with normal birth weight were 40(54%) and LBW 34 (46%). Mean S. vitamin D level in neonates with normal birth weight was 22.50 ± 7.90 ng/ml (7.50 – 40.20) and that of LBW 18.40 ± 8.10 ng/ml (7.10 – 39.40) which was statistically significant (p <0.05). Thirty-six (48.65%) neonates had normal vitamin D, 20 (27.02%) insufficiency and 18 (23.32%) deficiency. In LBW cases the vitamin D deficiency and insufficiency were more than that of normal birth weight which were statistically significant (p <0.05). Neonatal vitamin D positively correlated with birth weight (r = +0.45; p <0.001). Conclusion: In this study, 49% cases had normal S. vitamin D, 27% insufficiency and 24% deficiency. Among all the term neonates, LBW was 46% and there was significant positive correlation between S. vitamin D level of neonates and birth weight.
