Abstract
OBJECTIVE: To identify the factors associated with the increased risk of developing preeclampsia in twin pregnancies compared with those in singleton pregnancies. METHODS: We reviewed the obstetric records of all deliveries at > or =22 weeks' gestation managed at the Japanese Red Cross Katsushika Maternity Hospital between 2001 and 2007. RESULTS: The incidence of preeclampsia in the twin pregnancies (7.6%: 45 in 593) was significantly higher than that in the singleton pregnancies (1.7%: 196 in 11,311; P < 0.01). In singleton pregnancies, the developing preeclampsia was associated with maternal age at > or =35 years, primiparity, maternal BMI > or =25 before pregnancy, history of infertility therapies such as IVF and having a history of previous preeclampsia. In twin pregnancies, however, the developing preeclampsia was not associated with these variables. CONCLUSIONS: In Japanese women, the factors reported to be associated with the increased risk of preeclampsia in singleton pregnancies may not alter the increased risk of preeclampsia in twin pregnancies.
