Abstract:
Objective To explore the influencing factors and relationship of serum 25 (OH) D levels between late-term pregnant women and newborns. Methods A total of 600 pregnant women and 600 newborns were selected in Lishui Maternal and Children Health Institution during 2016 and information were collected by questionnaires. Serum 25 (OH) D levels in pregnant women's venous bloods and newborns' cord bloods were tested respectively before and after delivery. Results Serum 25 (OH) D levels in 600 pregnant women's venous bloods before delivery were (36.25 ±14.92) nmol/L and 75.16% (451 pregnant women) had lower serum 25 (OH) D levels. Serum 25 (OH) D levels in newborns' cord bloods after delivery were (29.59±16.13) nmol/L and 82.50% (495 newborns) had lower serum 25 (OH) D levels. The relationship of serum 25 (OH) D levels between pregnant women and newborns was significant (r=0.892, P<0.05) . Vitamin D supplementation during pregnancy in pregnant women (400 IU/d) 25 (OH) D level was higher than those of not (P<0.05) . Serum 25 (OH) D levels of pregnant women were influenced by seasons (P<0.05) as higher in summer and autumn and lower in spring and winter. Conclusion Serum 25 (OH) D levels of pregnant women and newborns in Lishui were lower and different among seasons. Serum 25 (OH) D levels of pregnant women could have influence on serum 25 (OH) D levels of newborns. It should be encouraged to increase vitamin D intakes and outdoor activities, especially in spring and winter.
