Maternal deaths in the US more than doubled over two decades

After two miscarriages, Ansonia became pregnant in 2020, and it was difficult. Doctors initially told her she was suffering from regular morning sickness, though she was vomiting blood. Ultimately, she was diagnosed with an excessive vomiting disorder.

Maternal deaths across the U.S. more than doubled over the course of two decades, and the tragedy unfolded unequally.

Black mothers died at the nation’s highest rates, while the largest increases in deaths were found in American Indian and Native Alaskan mothers. And some states — and racial or ethnic groups within them – fared worse than others.

The findings were laid out in a new study published Monday in the Journal of the American Medical Association. Researchers looked at maternal deaths between 1999 and 2019 — but not the pandemic spike — for every state and five racial and ethnic groups.
