ABSTRACT
Objective:
The correlation between in vitro fertilization-embryo transfer (IVF-ET) pregnancy and preeclampsia was studied by the propensity score matching.Methods:
4 823 pregnant women with delivery gestational weeks >24 weeks were selected, including 481 in IVF group and 4 342 in natural pregnancy group. The propensity score model was established by using 16 maternal covariates, and the propensity score matching samples (924 cases) were obtained to evaluate the correlation between IVF-ET and preeclampsia.Results:
⑴ Before matching, the incidence of preeclampsia in the IVF group was higher than that in the natural pregnancy group (9.8% vs 3.3%, P<0.05). Multivariate regression analysis showed that IVF-ET was a risk factor for preeclampsia (a OR=1.887; 95% CI 1.23-2.89, P=0.003); After matching propensity score, OR was 2.067 (95% CI 1.24-3.44, P=0.005), confirming that there was a significant association between IVF-ET and preeclampsia. ⑵ Before matching, the incidence of preeclampsia in IVF group was significantly higher than that in natural pregnancy group in singleton pregnancy (9.0% vs 3.1%, a OR=2.530, 95% CI 1.63-3.94, P>0.05); In twin pregnancy, there was no significant difference in the incidence of preeclampsia between the two groups (12.7% vs 7.5%, a OR=1.004, 95% CI 0.35-2.87, P=0.994); The result of propensity score matching is consistent with that before matching.Conclusions:
Propensity score matching analysis showed that the risk of preeclampsia increased after IVF-ET pregnancy, IVF-ET was an important risk factor for preeclampsia in singleton pregnancy, and IVF-ET did not increase the risk of preeclampsia in twin pregnancy. It is suggested that the correlation between IVF and preeclampsia may be disturbed by twin pregnancy.
