FRIDAY, May 27, 2022 (HealthDay News) — From 2007 to 2019, there were increases in the incidence of adverse pregnancy outcomes (APOs), including hypertensive disorders of pregnancy (HDP), according to a study published online May 18 in the Journal of the American Heart Association<\/em>.<\/p>\n Priya M. Freaney, M.D., from the Northwestern University Feinberg School of Medicine in Chicago, and colleagues performed a serial cross-sectional analysis of APO subtypes from 2007 to 2019 using maternal data from all live births that occurred in the United States. Age-standardized and age-specific rates of APOs were quantified per 1,000 live births. Data were included from 51,685,525 live births: 15, 24, and 6 percent to non-Hispanic Black, Hispanic, and Asian individuals, respectively.<\/p>\n The researchers found that age-standardized HDP rates approximately doubled from 2007 to 2019, from 38.4 to 77.8 per 1,000 live-births. There was a significant inflection point seen in 2014, marking an acceleration in the rate of increase of HDP from +4.1 percent per year from 2007 to 2014 to +9.1 percent per year from 2014 to 2019. When co-occurring in the same pregnancy with HDP, the rates of preterm delivery and low birth weight also increased significantly. Non-Hispanic Black individuals and older age groups had higher absolute rates of APOs. However, relative increases were similar across all age, racial, and ethnic groups.<\/p>\n “Our findings highlight the importance of clinical and public health efforts focusing on the equitable prevention of APOs and cardiovascular sequelae in birthing individuals and their offspring,” the authors write.<\/p>\n
