Lin D, Luo C, Chen G, et al. - Researchers examined the link of hypertensive disorders of pregnancy (HDPs)/preeclampsia (PE) with the presence of small for gestational age (SGA) and birthweight discordance, in this retrospective analysis of 2,131 twin pregnancies. They divided eligible pregnancies into four study groups: concordant pairs without SGA fetuses, discordant pairs without SGA fetuses, concordant pairs with SGA fetuses, and discordant pairs with SGA fetuses. Using binary logistic regression models and multinomial logit regression models, they compared the incidence of HDPs/PE and assessed PE severity between the study groups, respectively. Findings demonstrated a link of SGA with the development of HDP/PE, while discordant growth was shown to be related to the severity of PE. There is a need to further examine these links, using estimated fetal weight.
