This study examined perinatal outcomes comparing Asian and white parental units. Specifically we sought to examine maternal and paternal racial/ethnic differences.METHODS:
This is a retrospective cohort study comparing perinatal outcomes between four groups as follows (maternal/paternal): 1) Asian/white; 2) white/white; 3) white/Asian; and 4) Asian/Asian. The perinatal outcomes included preterm delivery, preeclampsia, gestational diabetes (GDM), birthweight less than 2500 g neonate, small-for-gestational-age neonates (SGA), birthweight greater than 4000 g, large-for-gestational-age neonates (LGA), cesarean section, and post-partum hemorrhage.RESULTS:
In the Asian/white parents compared to white/white parents (n=423,937) there are increased rates of preterm delivery (9.5% vs 7.3%), preeclampsia (2.7% vs 2.4%), GDM (9.6% vs 4.5%), neonatal birthweight less than 2500 g (4.6% vs 3.6%), SGA (4.8% vs 3.6%), cesarean section (34.3% vs 29.4%), and post-partum hemorrhage (4.2% vs 2.7%), respectively. In white/Asian parents compared to Asian/Asian parents (n=182,945) there are increased rates of preeclampsia (2.2% vs 1.8%), neonatal birthweight greater than 4000 g (7.9% vs 4.1%), and LGA neonates (7.0% vs 4.6%), respectively.CONCLUSION:
There are significant differences in perinatal outcomes between the interracial, Asian/Asian, and white/white parents. These differences are highly dependent on both maternal and paternal race.
