In the new study, researchers from the University of California, San Diego, and San Francisco, found that flooding contributed to the deaths of 152,753 infants — defined as children 11 months old and younger — in Bangladesh in the three decades between 1988 and 2017. The researchers used health surveys conducted by the United States Agency for International Development to collect data on more than 150,000 births over the course of the 30 years. They compared that data against high-resolution maps of major floods over that time span and found a stark difference in mortality risk: There were 5.3 more infant deaths per 1,000 births in flood-prone areas than in non-flood-prone areas. The authors extrapolated from this finding to estimate how many infant deaths, overall, were attributable to flooding in Bangladesh over the time period they studied.
