The coprimary outcomes were a composite maternal adverse outcome (preeclampsia, primary cesarean delivery, intensive care unit admission, blood transfusion, uterine rupture, or unplanned hysterectomy) and a composite neonatal adverse outcome (preterm birth, small for gestational age, Apgar's score &lt;5 at 5\u2009minutes, assisted ventilation&gt; 6\u2009hours, seizure, or death). Multivariable Poisson regression models were used to estimate adjusted relative risks (aRRs) and 95% confidence intervals (CIs).<\/jats:p><jats:p>\n            Results\u2003Between 2014 and 2019, the rate of chronic hypertension in pregnancy increased from 1.6 to 2.2%. After multivariable adjustment, an increased risk for the composite maternal adverse outcome was found in Black (aRR\u2009=\u20091.10, 95% CI\u2009=\u20091.09\u20131.11), Hispanic (aRR\u2009=\u20091.04, 95% CI\u2009=\u20091.02\u20131.05), and Asian\/Pacific Islander (aRR\u2009=\u20091.07, 95% CI\u2009=\u20091.05\u20131.10), compared with White individuals. Compared with White individuals, the risk of the composite neonatal adverse outcome was higher in Black (aRR\u2009=\u20091.39, 95% CI\u2009=\u20091.37\u20131.41), Hispanic (aRR\u2009=\u20091.15, 95% CI\u2009=\u20091.13\u20131.16), Asian\/Pacific Islander (aRR\u2009=\u20091.34, 95% CI\u2009=\u20091.31\u20131.37), and American Indian (aRR\u2009=\u20091.12, 95% CI\u2009=\u20091.07\u20131.17).
