THURSDAY, July 2, 2020 (HealthDay News) — Between 1997 and 2006, 0.44 percent of U.S. deaths were attributable to heat, according to a study published in the June issue of Environmental Epidemiology.

Kate R. Weinberger, Ph.D., from University of British Columbia in Vancouver, Canada, and colleagues estimated the number of deaths attributable to heat each year in the United States. Analysis included data for 297 counties, representing 61.9 percent of the U.S. population in 2000.

The researchers found that 5,608 U.S. deaths (0.44 percent of deaths) were attributable to heat annually from 1997 to 2006. Of these deaths, an average of 3,309 were attributable to moderate heat and an average of 2,299 were attributable to extreme heat each year. An annual average of 32.2 deaths per million were attributable to heat across the study counties, but this varied from 12.6 excess deaths per year per million individuals in the Southern Great Plains to 48.5 excess deaths per year per million people in the Northeast.

“This finding highlights the continued importance of interventions to protect public health during hot weather, particularly in light of projected increases in temperature in future decades resulting from continued climate change,” the authors write.
