Four out of five pregnancy-related deaths in the United States are preventable, according to new figures from the Centers for Disease Control and Prevention.
The report looked at data from the Maternal Mortality Review Committees (MMRCs) across 36 states between 2017 and 2019.

One-quarter of the deaths occurred during the pregnancy and the remaining 22% occurred on the day of delivery.
Mental health conditions -- such as deaths linked to suicide or an overdose from a substance use disorder -- made up the plurality of deaths at 23%, the report found.
Other underlying causes of pregnancy-related death included hemorrhaging; heart conditions; infections; thrombotic embolism, which a type of blood clot; cardiomyopathy, which is a disease of the heart muscle; and high blood pressure.
The report also looked at deaths broken down by race and ethnicity and found that Black Americans made up a disproportionate percentage of pregnancy-related deaths.
White Americans make up 59.3% of the population, according to the U.S. Census Bureau but accounted for 46.6% of deaths. Comparatively, Black Americans make up 13.8% of the population but 31.4% of deaths.
Leading underlying causes varied by race and/or ethnicity. For Black Americans, the leading underlying cause was heart conditions. For white Americans and Hispanic Americans, the leading underlying cause was mental health conditions.
The CDC recently awarded $2.8 million across the U.S. to support additional MMRCs in efforts to prevent future pregnancy-related deaths.
