Objective To estimate the changes in life expectancy and years of life lost in 2020 associated with the covid-19 pandemic. Design Time series analysis. Setting 37 upper-middle and high income countries or regions with reliable and complete mortality data. Participants Annual all cause mortality data from the Human Mortality Database for 2005-20, harmonised and disaggregated by age and sex. Main outcome measures Reduction in life expectancy was estimated as the difference between observed and expected life expectancy in 2020 using the Lee-Carter model. Excess years of life lost were estimated as the difference between the observed and expected years of life lost in 2020 using the World Health Organization standard life table. Results Reduction in life expectancy in men and women was observed in all the countries studied except New Zealand, Taiwan, and Norway, where there was a gain in life expectancy in 2020. No evidence was found of a change in life expectancy in Denmark, Iceland, and South Korea. The highest reduction in life expectancy was observed in Russia (men:-2.33, 95% confidence interval-2.50 to-2.17; women:-2.14,-2.25 to-2.03), the United States (men:-2.27,-2.39 to-2.15; women:-1.61,-1.70 to-1.51), Bulgaria (men:-1.96,-2.11 to-1.81; women:-1.37,-1.74 to-1.01), Lithuania (men:-1.83,-2.07 to-1.59; women:-1.21,-1.36 to-1.05), Chile (men:-1.64,-1.97 to-1.32; women:-0.88,-1.28 to-0.50), and Spain (men:-1.35,-1.53 to-1.18; women:-1.13,-1.37 to-0.90). Years of life lost in 2020 were higher than expected in all countries except Taiwan, New Zealand, Norway, Iceland, Denmark, and South Korea. In the remaining 31 countries, more than 222 million years of life were lost in 2020, which is 28.1 million (95% confidence interval 26.8m to 29.5m) years of life lost more than expected (17.3 million (16.8m to 17.8m) in men and 10.8 million (10.4m to 11.3m) in women). The highest excess years of life lost per 100 000 population were observed in Bulgaria (men: 7260, 95% confidence interval 6820 to 7710; women: 3730, 2740 to ...
