Life expectancy in the United States is expected to increase from 78.3 years in 2022 to 80.4 years in 2050, which is below that of other wealthy nations.
A study from the University of Washington’s Institute for Health Metrics and Evaluation found the U.S. is expected to lag in life expectancy gains compared to most other high-income nations and some middle-income nations. In terms of overall life expectancy, the U.S. is expected to fall to 66th out of 204 countries assessed in 2050, which is down from 49th in 2022.
Researchers are calling this an “alarming trajectory of health challenges” facing the country.
“In spite of modest increases in life expectancy overall, our models forecast health improvements slowing down due to rising rates of obesity, which is a serious risk factor to many chronic diseases and forecasted to leap to levels never before seen,” Christopher Murray, director of IHME and co-senior author of the new research, said in a news release.
“The rise in obesity and overweight rates in the U.S., with IHME forecasting over 260 million people affected by 2050, signals a public health crisis of unimaginable scale,” Murray continued.
