The GEE analysis showed a trend that longitudinal vitamin D deficiency during pregnancy leads to lower vitamin D concentrations in neonatal cord blood (RR = 1.17; 95% CI (1.05–1.36); p = 0.04).

Longitudinal Association Between Maternal Serum 25(OH)D Concentration Throughout Pregnancy and Neonatal Cord Serum 25(OH)D Concentration at Birth The generalized estimating equations (GEE) analysis demonstrated a significant trend of maternal vitamin D deficiency (25(OH)D <50 nmol/L) leads to lower neonatal vitamin D concentrations at birth through the assessment of cord blood (RR = 1.17; 95% CI (1.05–1.36); p = 0.04) (see Table 4 ).
