Trends in hypertensive disorders of pregnancy, chronic hypertension, and eclampsia among singleton deliveries in the U.S. from 1989 to 2020

(A) Trends in hypertensive disorders of pregnancy and chronic hypertension in the U.S. from 1989 to 2020 among singleton deliveries. The figure demonstrates the rate of hypertensive disorders of pregnancy and chronic hypertension over time. There was a significant 3.6% annual increase in the rate of hypertensive disorders of pregnancy (average annual percent change [AAPC] 3.6%, 95% CI 3.0% to 4.1%) and a significant 4.1% annual increase in the rate of chronic hypertension (AAPC 4.1%, 95% CI 3.3% to 4.9%).

(B) Trends in eclampsia in the U.S. from 1989 to 2020 among singleton deliveries. The figure demonstrates the rate of eclampsia over time. There was a significant 2.5% annual decline in the rate of eclampsia (AAPC −2.5%, 95% CI −4.0% to −1.0%).

(C) Average annual percentage change (AAPC) and 95% confidence interval for hypertensive disorders of pregnancy, chronic hypertension, and eclampsia from 1989 to 2020 among singleton deliveries.
