US Infant Mortality Rate Soars – Largest Increase in 2 Decades, CDC
The United States witnessed a whopping 20,538 in infant mortality in 2022, according to the latest report from the Centres for Disease Control and Prevention’s National Vital Statistics System (CDC).
The US saw its first year-to-year increase in infant mortality rate since the period of 2001–2002.
The provisional infant mortality rate for 2022 jumped 3% from the previous year, according to a report from the National Centre for Health Statistics.
The numbers came after a steady decline of 22% from 2002 to 2021.
- In a comprehensive breakdown of the data, the report titled, “Infant Mortality in the United States: Provisional Data from the 2022 Period Linked Birth/Infant Death File,” shows shocking figures.
- The provisional infant mortality rate for 2022 stood at 5.60 infant deaths per 1,000 live births, a slight increase from 5.44 in 2021.
- The total number of infant deaths in 2022 was 20,538, marking a 3% rise from the 19,928 infant deaths recorded in 2021.
- The year 2022 saw a surge in neonatal and postnatal infant deaths. The neonatal mortality rate rose by 3%, from 3.49 to 3.58, while the postneonatal mortality rate increased by 4%, moving from 1.95 to 2.02.
- Disturbingly, mortality rates surged among infants born to American Indian and Alaska Native and White women. Specifically, rates for infants of American Indian and Alaska Native, non-Hispanic women jumped from 7.46 to 9.06, and for White, non-Hispanic women, it increased from 4.36 to 4.52.
- Infants born to women aged between 25 to 29 also saw a significant rise in mortality rates, moving from 5.15 to 5.37.
- Preterm infants, especially those born before 34 weeks of gestation, experienced a notable increase in mortality rates.
- Male infants weren’t spared either, with their mortality rate climbing from 5.83 infant deaths per 1,000 live births to 6.06.
- Four states, namely Georgia, Iowa, Missouri, and Texas, reported increased infant mortality rates.
- Two of the top ten causes of infant deaths, maternal complications and bacterial sepsis, also saw a rise in mortality rates.
As the official CDC website noted:
This is the first report to present provisional data on infant mortality rates by selected maternal and infant health characteristics for the United States based on the linked birth/infant death file. Previous reports used only final data.
For the linked birth/infant death data, birth certificates and death certificates are linked to provide additional information only available from the birth certificate, such as maternal age, gestational age, and a number of pregnancy, labor and delivery, and infant characteristics.
This analysis uses all linked birth/infant death records received and processed by National Center for Health Statistics for calendar year 2022 as of July 27, 2023. Data from birth certificates and death certificates are collected via the National Vital Statistics System.
According to the summary of the report:
The infant mortality rate for the United States rose 3% from 2021 to 2022, the first year-to-year increase in the rate since 2001 to 2002.
From 2002 to 2021, the infant mortality rate declined 22%. From 2021 to 2022, increases in mortality rates were observed for neonatal and postneonatal infant deaths, infants born to American Indian and Alaska Native and White women, and infants born to women ages 25–29.
Rates also increased for infants born preterm, male infants, and for infants in four states (Georgia, Iowa, Missouri, and Texas).
Mortality rates increased significantly for 2 of the 10 leading causes of death: maternal complications and bacterial sepsis.
Although not statistically significant, rates generally increased for most other race and Hispanic origin, maternal age, and gestational age groups, as well as for female infants, in a majority of states, and for 3 of the 10 leading causes of death.
Marie Thoma, a renowned researcher from the University of Maryland who specializes in maternal and infant mortality, expressed her concerns about the trend.
“It’s definitely concerning, given that it’s going in the opposite direction from what it has been,” she told AP.
Dr. Eric Eichenwald, a Philadelphia-based neonatologist, echoed Thoma’s sentiments, labeling the new data as “disturbing.”
He pointed out that while experts have been speculating on the reasons behind this sudden rise, a definitive cause remains elusive.
