A new study challenges the prevailing view on maternal mortality rates in the US, finding stable rates between 1999-2002 and 2018-2021. The researchers used a more accurate approach to identify and classify maternal deaths, refuting the idea of dramatic increases.
A new study by Rutgers Health and other universities found that the US maternal death rate is likely being overestimated due to flawed surveillance methods. The true rate is estimated to be around 10 deaths per 100,000 live births, nearly half of the CDC's reported figure.
