Introduction:
Women of color in the United States have increased risk of maternal morbidity and higher risk of cesarean delivery (CD) compared to white women. This study aims to determine if maternal race/ethnicity influenced mode of delivery (MOD) of twin gestations.
Methods:
IRB-approved, retrospective cohort study of all twin deliveries at a single institution between 1/1/2001 and 12/31/2018. Pregnancies delivered < 24 weeks or with intrauterine fetal demise were excluded. The primary exposure, self-reported race/ethnicity, was categorized into 5 groups: White, Hispanic, non-Hispanic Black, Asian/Pacific Islander/Alaska Native, and Other/Mixed. The primary outcome was CD. Statistical analyses included univariate analysis via Chi Square and ANOVA and logistic regression analysis.
Results:
796 pregnancies were included. 377 (47.8%) of participants identified as white, 236 (29.9%) as Hispanic, 83 (10.5%) as Asian/PI/AN, 44 (5.6%) as Black, and 50 (6.3%) as Other. BMI, maternal age at delivery, chorionicity, and parity were different by race/ethnicity groups but gestational age at delivery was not. The overall rate of CD was 71.1% and did not vary by race/ethnicity (p=0.51). There were no differences by race/ethnicity when analysis was limited to those delivering >34 weeks and birthweights >2500g (p=0.07) or among only nulliparous women (p=0.77). In multivariable analysis, only nulliparity was associated with increased risk of CD (p= < 0.01).
Conclusion/Implications:
Rate of CD for twin gestations is high but was not related to maternal race/ethnicity in this cohort. Further study is needed to evaluate the indications for cesarean deliveries across racial/ethnic groups in twin gestations as this was not examined in this cohort.
