Preeclampsia and fetal growth(Xiong et al, Am J Obstet Gynecol 1999;180:207-13)(Xiong et al, Am J Obstet Gynecol 2000;183:148-55)
Data from Canada, China, Europe, South-Africa, US (CPEP trial) show that preeclampsia is also associated with an increased rate of high birth weight.

Most babies born to mothers with preeclampsia, especially born at term, have normal fetal growth. These findings do not endorse the currently held theory that reduced uteroplacental perfusion is the unique pathophysiologic process in preeclampsia.
