Since the US constitutional right to abortion was overturned in mid-2022, infant mortality has been higher than expected in the country every month, according to an investigation of US Centers for Disease Control and Prevention data. The team looked at infant deaths from any cause across the US, as well as deaths in infants with congenital anomalies, following previous research which showed an increase in infant mortality in Texas after abortion was banned. The researchers say while the data they used from 2023 onwards is provisional and could be revised later, as it stands infant mortality was higher than expected in the months following the overturning of the right to abortion, and no month since has seen a lower than expected infant mortality rate. They say the mortality rate increased more among infants with congenital anomalies, suggesting a higher number of frail infants being born is a main contributor to the statistics.
