Abstract
OBJECTIVE: To understand whether maternal, perinatal, and systems-level factors can be identified to explain racial/ethnic disparities in cesarean delivery rates. STUDY DESIGN: This retrospective cohort study included nulliparous women with singleton gestations who delivered at a tertiary care center from 2015 to 2017. Maternal, perinatal, and systems-level factors were compared by race/ethnicity. Multilevel multivariable logistic regression was used to identify whether race/ethnicity was independently associated with cesarean. Effect modification was evaluated using interaction terms. Bivariable analyses and multinomial logistic regression were used to determine differences in indication for cesarean. RESULTS: Of 9,865 eligible women, 2,126 (21.5%) delivered via cesarean. The frequency of cesarean was lowest in non-Hispanic white women (19.2%) and highest in non-Hispanic black women (28.2%; p < 0.001). Accounting for factors associated with cesarean delivery did not lessen the odds of cesarean associated with non-Hispanic black race (aOR: 1.58, 95% CI: 1.31-1.91). Compared with non-Hispanic white women, non-Hispanic black women were more likely to undergo cesarean for nonreassuring fetal status (aOR: 2.73, 95% CI: 2.06-3.61). CONCLUSION: Examined maternal, perinatal, and systems-level risk factors for cesarean delivery did not explain the racial/ethnic disparities observed in cesarean delivery rates. Increased cesarean delivery for nonreassuring fetal status contributed substantially to this disparity. Thieme. All rights reserved.
