US infant mortality spiked after right to abortion overturned: Study

WASHINGTON – US infant mortality surged in the months following the Supreme Court decision to overturn the national right to abortion, driven by a rise in the number of babies with birth defects, a study said Oct 21.

The findings highlight the consequences of restricting abortion access across much of the country, according to the authors of the paper in Jama Paediatrics.

They also align with previous research published earlier in 2024, which focused specifically on Texas, a state that implemented a six-week abortion ban in 2021.

Restoring abortion protections dismantled by a Supreme Court shaped during Donald Trump’s presidency has emerged as a cornerstone in US Vice-President Kamala Harris’ campaign for the Nov 5 election.

Researchers Maria Gallo and Parvati Singh of The Ohio State University analysed a national database of birth outcomes, examining historical trends and comparing them to data from the 18 months following the June 2022 Dobbs versus Jackson ruling.

Birth outcomes in large populations such as the entire US are generally stable except for predictable seasonal peaks and valleys which they accounted for in their analysis, the authors said.

“We found that in the months after the Dobbs decision, infant mortality in the United States was higher than that we would have expected,” Dr Gallo, a professor at the university’s division of epidemiology, told AFP.

In three months – October 2022, March 2023 and April 2023 – the rates of infant mortality were about 7 per cent higher than typical, leading to an average of 247 more infant deaths in each of those months.

The majority of the increase was attributed to congenital anomalies. These include things like heart defects, neural tube defects, chromosomal abnormalities, and other organ system malformations.

“These are cases in which before Dobbs, people would have been able to have an abortion rather than have to continue the pregnancy and go through the experience of having an infant die,” Dr Gallo added.

The period since the Dobbs decision has been marked by rapid changes in state-level abortion laws.

At present, 21 states either ban terminating pregnancies or restrict the procedure to gestational limits of 18 weeks or fewer.

Abortion is on the ballot in 10 states

when US voters go to the polls for the presidential and congressional elections, with activists hoping to secure new legal protections for the procedure.

Next, the researchers hope to establish whether the infant mortality rise was seen in all states or whether it was concentrated most among those with state policies or laws that restrict access to abortion.

“There’s a broader human toll to consider, including mental health consequences of being denied abortion care or being forced to carry a foetus with a fatal genetic abnormality to term,” Dr Singh said in a statement. AFP
