16 Jul Prevalence and Risk Factors of Preeclampsia in Twin Pregnancies
Although the development of preeclampsia (PE) is thought to be the result of placental dysfunction, it is still unclear if the development of preeclampsia is the same in both single and twin pregnancies. Previous studies reported conflicting results regarding the incidence, characteristics and risk factors for PE in twins compared with singleton pregnancies. Different results were also reported regarding twins and hypertensive disorders in pregnancy. These studies are limited by lack of adjustments for confounders and small sample sizes. This retrospective study compares the rate and risk factors for gestational hypertension (GHTN) and PE between twins and singleton pregnancies using a large provincial population-based cohort from the Better Outcomes Registry and Network (BORN) database while controlling for potential confounding variables. This study includes all women who gave birth in Ontario, Canada between April 2012 and March 2016.
