Potential Association between Marital Status and Maternal and Neonatal Complications and Placental Pathology in Singleton Pregnancy

Abstract

Maternal marital status, educational levels, and income levels were associated with adverse pregnancy outcomes and placental inflammatory changes, preterm delivery, and stillbirth. We aimed to examine the association of marital status with maternal and neonatal complications and placental pathology in singleton pregnancy. A total of 3724 singleton placentas with maternal neonatal and placental pathology data were included in the study, and there were statistically significant associations between marital status and maternal age, race/ethnicity, maternal BMI at delivery, neonatal birth weight, preeclampsia, and preterm delivery. There were significant associations between marital status and maternal inflammatory response, maternal vascular malperfusion, and meconium stain of fetal membranes. These data demonstrated that marital status affects not only the maternal well-being during pregnancy, but also neonatal birth data and placental pathology.
