Totally, thirty six,297 people escort list were accumulated. Following different regarding 894 (2.46%) ladies having multiple maternity, 5957 (%) having shed medical information, 1157 (step three.19%) to possess not starting Supplement D test and 4895 (%) outside of the basic trimester, results from twenty-two,394 lady had been fundamentally utilized in analyses (Fig. 1). ten nmol/L (suggest ± SD) having an overall total variety of 2.00– nmol/L (Table step 1, Fig. 2). Of one’s entire population, fifteen,696 female (%) was basically twenty five(OH) D deficient, 6981(%) have been not enough and just 2583 (twenty two.2%) had sufficient twenty-five(OH) D account (Fig. 3).
Delivery regarding maternal Vitamin D position in the 1st trimester regarding maternity. Y-axis: event matters; X axis: new intensity of maternal serum supplement D (nmol/L)
The maternal 25(OH)D levels varied with age, pre-pregnancy BMI, season when blood was collection, number of previous pregnancy while no interaction was found in the mode of birth, and family history of diabetes or thyroid disease. Women with older age, higher pre-pregnancy BMI(P < 0.001) and less previous pregnancy times(P = .007) indicate a worse 25(OH)D status. In consistent with seasonal exposure of ultraviolet rays, concentration of vitamin D fluctuated along with recorded season, with the lowest in winter ( ± 15. 60 nmol/L) and the highest in summer ( ± nmol/L), all were lower than 50 nmol/L (Table 2).
Table 3 summarized the maternal outcomes of the population. Interestingly, Women diagnosed as vitamin D insufficiency had a higher incidence rate of gestational diabetes compared with vitamin D deficiency (% vs %, Pbonferroni = .020). The incidence rate of intrauterine infection, preeclampsia were different among groups but not significant after multiple comparison correction. No associations were found between gestational age (both category and numeric values), cesarean section rate, premature rupture of membranes, intrahepatic cholestasis and 2-h postpartum hemorrhage.
Most importantly, newborns delivered by women with deficient vitamin D status had a higher incidence rate of admission to NICU (Deficiency: % vs Insufficiency: % vs Sufficiency: %, Pbonferroni = .002) and a longer stay (Deficiency: 6.20 ± 4.10 vs Insufficiency:5.90 ± 3.10 vs Sufficiency: 5.10 ± 2.10, Pbonferroni = .010). Meanwhile, no correlation was observed between maternal vitamin D status and the birth weight, birth height and other outcomes. (Table 4).

Interestingly, maternal vitamin D deficiency was a dependent risk factor for admission to NICU (unadjusted OR = 1.350, 95%CI (1.045–1.744), P =.022; adjusted OR = 1.305, 95%CI (1.010–1.687), P = .042). To determine the potential confounding factor, we further analyzed demographic baseline of mothers and neonatal outcomes between newborns whether to be admitted to NICU (Table 6). The results indicated that women whose infants were transferred to NICU after delivery had a slightly lower vitamin D concentration ( ± nmol/L vs ± , P = .010). Furthermore, lower maternal age ( ± 3.50 vs ± 3.70, P =.006), higher pre-pregnancy BMI ( ± 3.40 vs ± 3.60, P ? .001) and gestational age at birth ( ± 1.20 vs ± 2.40, P = .001) was observed in NICU group. NICU group had a lower cesarean section rate (% vs %, P ? .001), Apgar score (9.70 ± 0.90 vs 9.90 ± .59, P < .001), birth weight ( ± vs ± P ? .001), and birth length( ± 2.40 vs ± 1.10, P ? .001).
