A study involving Oxford University has found that the Covid-19 pandemic had a significant impact on other causes of death, writes the Whitney Gazette. The international study, which involved researchers from Oxford's Leverhulme Center for Population Sciences, examined data on causes of death in 24 countries before and during the pandemic. Researchers found that in 2020, life expectancy fell in all but four of the countries studied, with the U.S. experiencing the largest decline of 2.1 years for men. In 2021, most countries saw a further decline in life expectancy, with women in Bulgaria and men in Latvia losing more than two years.  The study also found that cardiovascular disease is the main cause of the decline in life expectancy during the first two years of the pandemic, especially in Russia and Eastern Europe. In Russia, the loss due to cardiovascular disease in 2020 was 5.3 months, while in Bulgaria the loss was 5.5 months in 2021. However, suicide and accidental deaths generally declined during the pandemic years, the researchers found.
