Americans Growing Overweight... Average Life Expectancy Drops 17 Ranks to 66th by 2050

Average Life Expectancy of Americans Predicted to Reach 80.4 Years by 2050
Slight Increase but Drops to 66th Globally
"Health Improvements Slow Due to Rising Obesity Rates"

A study has revealed that the average life expectancy of Americans, currently ranked 49th in the world, is expected to drop to 66th by 2050.

According to recent research published in The Lancet by a team from the University of Washington, the average life expectancy in the United States is projected to slightly increase from 78.3 years in 2022 to 80.4 years in 2050, but its global ranking is expected to fall from 49th to 66th.

The researchers evaluated the impact of hundreds of diseases and health risks on the U.S. and its states, comparing these with over 200 other countries. They found that the average life expectancy for American men and women is expected to rise from 78.3 years in 2022 to 79.9 years in 2035 and 80.4 years in 2050. The life expectancy improvement for American women is expected to be less than that for men, leading to a slight narrowing of the gender gap in life expectancy.

However, it is notable that by 2050, the average life expectancy of Americans is projected to be lower than that of sub-Saharan African countries such as Nigeria, Kenya, and South Africa, as well as war-torn countries like Syria, Afghanistan, and Yemen. The primary reason cited for this is 'obesity.'

Dr. Christopher Murray, director of the Institute for Health Metrics and Evaluation at the University of Washington, stated, "Despite a slight increase in overall life expectancy, the rise in obesity rates is expected to slow health improvements." He added, "Obesity is a serious risk factor for many chronic diseases and is projected to surge to unprecedented levels." He predicted, "By 2050, 260 million Americans will be overweight or obese," warning that this signals an unimaginable public health crisis.

Conversely, what would happen if major health risk factors such as high BMI, fasting plasma glucose, systolic blood pressure, sodium intake, and smoking were eliminated among Americans? The researchers' analysis showed that over 12 million deaths could be prevented. In particular, mortality rates from diabetes, heart disease, and chronic kidney disease could decrease by 85-100%.

Furthermore, if the U.S. eliminated risks in three key areas?environmental, behavioral and metabolic risks, child nutrition, and vaccinations?deaths could be reduced by approximately 550,000 by 2050, potentially increasing life expectancy by about four years.

Dr. Stein Emil Vollset, who led the study, emphasized, "The rapid decline in the U.S. global ranking from 2022 to 2050 raises urgent concerns that immediate action is needed," and stressed, "Newer and more effective health strategies and policies must be developed."
