Here; an excerpt:

The study — published Thursday on the preprint server medRxiv, which means it has not been peer-reviewed — found that after falling nearly 1.9 years in 2020, life expectancy in the US decreased another 0.4 years in 2021.  In the decade before the pandemic, life expectancy in the US changed by an average of less than 0.1 years annually, according to data from the US Centers for Disease Control and Prevention.

 

Changes to life expectancy amid the Covid-19 pandemic widened an existing gap between the US and other high-income countries, the new report shows. Among a set of 19 peer countries, life expectancy dropped only a third as much as in the US in 2020 (down 0.6 years, on average) and rebounded in 2021, with an average increase of about 0.3 years.
