The Effect of Parental Race on Fetal

twin pregnancy


Despite major improvement in perinatal healthcare in the United States in the past two decades, black infants continue to have poorer health status than white infants. Large-scale studies in all infants (majority being singletons) have found higher rates of infant mortality in blacks than whites. The higher mortality rates in blacks seem largely attributed to their higher rates of preterm birth and low birth-weight (LBW) as compared with whites.

Twin pregnancies are different from singleton pregnancies in many physiologic and pathologic aspects. These differences make twins more vulnerable to environmental hazards both inside and outside of the mother’s uterus. Compared with singletons, twins have five-fold increased risk of fetal death, seven-fold increased risk of neonatal death, and five-fold increased risk of infant death.

Previous studies have found that maternal race was associated with the risks of LBW and fetal and infant mortality in twins, with substantially increased rates in blacks than in whites. The magnitude of black-white differences in fetal-infant mortality seems smaller in twins than in singletons, however. The objective of this study was to assess the association between parents’ race and fetal and infant deaths in twins, using a large twin registry data.
