Infant mortality in the U.S. went up 3% between 2021 and 2022, according to a CDC report published Nov. 1. It's the first time the rate has gone up year over year since 2001-2002.
The neonatal mortality rate also increased 3% during the same time period. Postneonatal mortality also rose by 4%.
Researchers also found that rates state-by-state also increased significantly in four locations: Texas, Georgia, Missouri and Iowa.
"This report, the first based on provisional data from the linked birth/infant death file, provides more timely information than reports based on final linked birth/infant death file data and provides detail by maternal and infant characteristics," CDC researchers wrote of their findings.
This news follows a report the World Health Organization published in May detailing how both maternal and infant health worldwide is not where it needs to be.
