The study, published in the International Journal of Epidemiology, examined data sets from 29 different countries, and found that 27 saw reductions in life expectancy. On average, it took these countries 5.6 years to gain one year of life expectancy.
The loss of one year or greater in life expectancy was seen in 11 countries for men and eight countries for women.
The United States was hit particularly hard by the pandemic, with men losing an average of 2.2 years and women 1.7 years from their life expectancy. In the US, people under the age of 60 were the primary cause for the loss of life expectancy, which was the inverse for individuals in Western Europe.
The study largely attributes the loss in life expectancy to the COVID-19 pandemic, but does quantify for non-Covid related deaths.
