U.S. infant mortality rate sees biggest increase in 2 decades: CDC
Global News
The CDC's report also noted larger increases for two of the leading causes of infant deaths — maternal complications and bacterial meningitis.
The U.S. infant mortality rate rose 3% last year — the largest increase in two decades, according to the Centers for Disease Control and Prevention.
White and Native American infants, infant boys and babies born at 37 weeks or earlier had significant death rate increases. The CDC’s report, published Wednesday, also noted larger increases for two of the leading causes of infant deaths — maternal complications and bacterial meningitis.
“It’s definitely concerning, given that it’s going in the opposite direction from what it has been,” said Marie Thoma, a University of Maryland researcher who studies maternal and infant mortality.
Dr. Eric Eichenwald, a Philadelphia-based neonatologist, called the new data “disturbing,” but said experts at this point can only speculate as to why a statistic that generally has been falling for decades rose in 2022.
RSV and flu infections rebounded last fall after two years of pandemic precautions, filling pediatric emergency rooms across the country. “That could potentially account for some of it,” said Eichenwald, who chairs an American Academy of Pediatrics committee that writes guidelines for medical care of newborns.
Infant mortality is the measure of how many babies die before they reach their first birthday. Because the number of babies born in the U.S. varies from year to year, researchers instead calculate rates to better compare infant mortality over time. The U.S. infant mortality rate has been worse than other high-income countries, which experts have attributed to poverty, inadequate prenatal care and other possibilities. But even so, the U.S. rate generally gradually improved because of medical advances and public health efforts.
“Today’s data underscores that our failure to better support moms before, during, and after birth is among the factors contributing to poor infant health outcomes,” Dr. Elizabeth Cherot, chief executive of the March of Dimes, said in a statement.
The national rate rose to 5.6 infant deaths per 1,000 live births in 2022, up from from 5.44 per 1,000 the year before, the new report said.
