Hypertensive disorders of pregnancy affect up to 8% of pregnancies, but updated national trends are lacking. We performed a repeated cross-sectional analysis of individuals with singleton pregnancies who delivered at greater than 20 weeks of gestation, with data in the U.S. National Vital Statistics System from 1989 to 2020. Temporal trends in hypertensive disorders of pregnancy, chronic hypertension, and eclampsia were characterized using joinpoint regression. Overall, 122,329,914 deliveries were included. Hypertensive disorders of pregnancy increased from 2.79% in 1989 to 8.22% in 2020, representing an average annual percentage change (AAPC) of 3.6% (95% CI 3.0-4.1%). Chronic hypertension increased (AAPC 4.1%, 95% CI 3.3-4.9%), whereas eclampsia decreased (AAPC -2.5%, 95% CI -4.0% to -1.0%). Hypertensive disorders of pregnancy are associated with significant morbidity and mortality; the rising incidence is concerning.
妊娠高血压疾病影响多达 8%的妊娠,但缺乏最新的全国趋势数据。我们对 1989 年至 2020 年期间在美国国家生命统计系统中分娩超过 20 周的单胎妊娠个体进行了重复横断面分析。使用连接点回归来描述妊娠高血压疾病、慢性高血压和子痫前期的时间趋势。共有 122329914 例分娩纳入研究。妊娠高血压疾病从 1989 年的 2.79%增加到 2020 年的 8.22%,代表平均年百分比变化(AAPC)为 3.6%(95%CI 3.0-4.1%)。慢性高血压增加(AAPC 4.1%,95%CI 3.3-4.9%),而子痫前期减少(AAPC-2.5%,95%CI-4.0%至-1.0%)。妊娠高血压疾病与显著的发病率和死亡率相关;发病率的上升令人担忧。
