Observational study links maternal vitamin D levels to infant growth metrics and cord blood FGF23, suggesting potential implications for fetal development.
Key Points
Maternal serum 25(OH)D concentration significantly affects infant length and weight for up to 6 months.
Cord blood FGF23 levels are positively correlated with maternal vitamin D, indicating a role in fetal growth.
Infant growth indicators were assessed using WHO-standardized Z-scores for length, weight, and head circumference.
No significant differences in obstetric complications were observed across 25(OH)D quartiles, focusing on growth outcomes instead.
