The research team assembled an unprecedented dataset on mortality from 29 countries, spanning most of Europe, the US and Chile – countries for which official death registrations for 2020 had been published. They found that 27 of the 29 countries saw reductions in life expectancy in 2020, and at a scale which wiped out years of progress on mortality, according to the paper published today in the International Journal of Epidemiology.
Women in 15 countries and men in 10 countries were found to have a lower expectancy at birth in 2020 than in 2015, a year in which life expectancy was already negatively affected by a significant flu season.
According to the study’s co-lead author Dr José Manuel Aburto, ‘For Western European countries such as Spain, England and Wales, Italy, Belgium, among others, the last time such large magnitudes of declines in life expectancy at birth were observed in a single year was during WW-II.
But, he says, the scale of the life expectancy losses was stark across most countries studied, ‘Twenty two countries included in our study experienced larger losses than half a year in 2020. Females in eight countries and males in 11 countries experienced losses larger than a year. To contextualize, it took on average 5.6 years for these countries to achieve a one-year increase in life expectancy recently: progress wiped out over the course of 2020 by COVID-19.’
