Abstract:

Objective To investigate the synergistic role of vitamin D(VD) deficiency and high blood glucose in pregnancy outcomes in patients with preeclampsia(PE). Methods Totally,173 PE patients in Bayingol Mongolian Autonomous Prefecture People's Hospital from January 2020 to March 2022 were enrolled. According to the pregnancy outcomes,they were classified into good pregnancy outcome group(118 cases) and poor pregnancy outcome group(55 cases). The differences of general clinical data,25-hydroxyvitamin D[25(OH)D],blood glucose and other biochemical indexes were compared between the 2 groups. Multivariate Logistic regression analysis was used to evaluate the independent risk factors for adverse pregnancy outcomes in PE patients,and the interaction of 25(OH)D and blood glucose on adverse pregnancy outcomes was analyzed by additive interaction model. Logistic regression model was used to analyze the relationship between 25(OH)D,blood glucose and the risk of adverse pregnancy outcomes in PE patients. Results VD deficiency and high blood glucose were independent risk factors for adverse pregnancy outcomes in PE patients,and they had interactive effects on the occurrence of adverse pregnancy outcomes in PE patients. With the increase of 25(OH)D level,the probability of adverse pregnancy outcomes decreased gradually. With the increase of blood glucose level,the probability of adverse pregnancy outcomes increased gradually. There was a negative correlation between 25(OH)D and adverse pregnancy outcomes,especially when 25(OH)D<30 ng·mL-1,and the probability of adverse pregnancy outcomes decreased with the increase of 25(OH)D level. There was a positive correlation between blood glucose and adverse pregnancy outcomes,especially when blood glucose <7.5 mmol·L-1,the probability of adverse pregnancy outcomes decreased with the decrease of blood glucose level. The synergistic interaction value of 25(OH)D and blood glucose in predicting adverse pregnancy outcomes in PE patients was greater than that of the 2 alone. Conclusions VD deficiency and high blood glucose are independent risk factors for adverse pregnancy outcomes in PE patients and influence each other.
