Abstract
Vitamin D deficiency is common in Southeast Asia but there are limited data in pregnant women and neonates. This study aimed to determine the prevalence of vitamin D deficiency in cord blood of newborns and the association with maternal vitamin D status. A total of 94 pregnant women and their neonates were included. Clinical data and venous maternal blood for calcium, phosphate, albumin, alkaline phosphatase, magnesium, intact parathyroid hormone (iPTH), and vitamin D (25OHD) were obtained on the day of labor. Cord blood was collected following delivery to evaluate vitamin D status of newborns. Mean serum maternal and cord blood 25OHD levels were 25.42 ± 8.07 and 14.85 ± 5.13 ng/mL. The prevalence of vitamin D deficiency (25OHD < 12 ng/mL) and insufficiency (25OHD 12–20 ng/mL) in cord blood of newborns were 20.2 and 69.1%, respectively. There was a significant correlation between maternal and cord blood vitamin D levels (r = 0.86; P < 0.001). The factors associated with cord blood vitamin D deficiency were low maternal 25OHD level and no vitamin D supplement during pregnancy.
Conclusion: There is a high prevalence of vitamin D deficiency among Thai neonates. Adequate prenatal vitamin D supplementation should be implemented as routine antenatal care.
What is Known:
• Vitamin D deficiency is prevalent in Southeast Asia. • There are widespread vitamin D deficiency among Thai populations including pregnant women. |
What is New:
• There is a high prevalence of vitamin D deficiency among Thai neonates. • The factors associated with cord blood vitamin D deficiency are low maternal vitamin D level and no vitamin D supplement during pregnancy. |
