Objectives: Vitamin D plays an important role in the release of the placenta and implantation, and low levels are a risk factor for pre-eclampsia. Studies have also shown that symptomatic treatment of vitamin D3 deficiency can effectively reduce the risk of pre-eclampsia. In this study, vitamin D3 supplementation was performed on the risk of pre-eclampsia to observe its effect.
Methods: From January 2016 to December 2018, 450 women with maternal treatment and delivery in our hospital underwent an open-label randomized study. The pregnant women were divided into low-dose, medium-dose, and high-dose groups. Compare the incidence of pre-eclampsia and the dose effect of vitamin D levels.
Results: In the maternal and perinatal periods of the 450 maternal women, the 25[OH] index of the three groups of pregnant women was significantly increased, while the high-dose increase index was more obvious. The relative risk reduction rate was significantly lower. Compared with the low-dose and middle-dose groups, the high-dose group had a significantly lower incidence of pre-eclampsia, while the IUGR index was lower, and other obstetric indicators were comparable.
Conclusion: Vitamin D supplementation can effectively reduce the incidence of pre-eclampsia, while reducing the IUGR index, which has important value and significance in its clinical application.
