Influence of maternal characteristics on gestational serum 25(OH)D concentration
The maternal characteristics that affect the status of vitamin D were analyzed. Compared with young women, serum 25(OH)D concentration was higher in advanced women(39.09±15.55nmol/L vs 36.46±13.96nmol/L, P=0.006 ). While compared with nulliparous, serum 25(OH)D concentration was higher in multiparous(37.78±13.60nmol/L vs 36.16±14.65nmol/L,P=0.018).
