Percentage of babies with bronchopulmonary dysplasia by race and gestational age in PROP cohort of babies <29 weeks gestation.

Data were collected for 707 newborn infants born at <29 weeks gestation for whom both race and BPD outcome were known. For race based on maternal self-report, and using the modified Shennan definition of BPD (supplemental oxygen at 36 weeks postmenstrual age), the rate of BPD was lower for Black babies at each week of GA at birth. The odds ratio for BPD was 0.60 (95% confidence interval 0.42-0.85, P=0.004) for Black infants compared with White infants after adjusting for gestational age, intubation at birth, antenatal steroid use, surfactant use within 72 hours after birth, and sibling correlations.
