[Risk factors of recurrent preeclampsia and its relation to maternal and offspring outcome].
To investigate the risks of recurrent preeclampsia and observe the incidence and long-term prognosis of recurrent preeclampsia.



One hundred and fifteen women with preeclampsia history admitted in Women's Hospital, Zhejiang University School of Medicine from January 2009 to December 2013 were enrolled in the study. The clinical data were retrospectively analyzed.



Among 115 women with preeclampsia, 82 cases (71.3%)had recurrent preeclampsia. The onset age, the pregnant interval time, regular prenatal check-up, weight gain during pregnancy, body mass index (BMI), hyperlipidemia, fetal growth restriction (FGR), maternal family history were closely associated with recurrent preeclampsia (P<0.05). Logistic regression analysis showed that the pregnant interval time, BMI, FGR were independent risk factors for preeclampsia recurrence. Compared with the preeclampsia in first pregnancy, the mather had earlier onset and termination of pregnancy, higher blood pressure, higher rate of urine protein ≥ 2+ and higher rate of complications in recurrent preeclampsia. The offspring had higher rate of preterm birth, especially the time of birth for 34 weeks or earlier and lower birth weight (P<0.05). The incidence of chronic hypertension in recurrent preeclampsia group was higher than that in no recurrence group (47.5% vs 23.3%, P<0.05); the overweight rate of first pregnant offspring in recurrence group was higher than that in no recurrence group (31.25% vs 6.70%, P<0.05).



The onset age, time interval, regular prenatal check-up, weight gain during pregnancy, BMI, hyperlipidemia, FGR, maternal family history are closely associated with recurrent preeclampsia, and the pregnant interval time, BMI, FGR are independent risk factors for preeclampsia recurrence. Recurrent preeclampsia has more serious clinical outcome and complications, and prevention need to be emphasized.
