I read an interesting article about the leading Causes of Death in the US During the COVID-19 Pandemic, from March 2020 to October 2021. It was written by Meredith S. Shiels, PhD, MHS1; Anika T. Haque, MPH1; Amy Berrington de González, PhD1; et al Neal D. Freedman, PhD, MPH1 and published online by Jama Internal Medicine online July 5, 2022. Here are some excerpts from the article.
In 2020, heart disease and cancer were the leading causes of
death in the US, accounting for 1.29 million deaths, followed by COVID-19,
accounting for 350 000 deaths.1-3 The pandemic may also have indirectly led to
increases in other causes of death, including heart disease, diabetes,
Alzheimer disease, and unintentional injuries.2,4 We examined the leading
causes of death in the US, overall and in various age groups, from March 2020
to October 2021.
Methods
We obtained final national death certificate data for 2020
and provisional data for 2021 from the Centers for Disease Control and
Prevention (accessed May 5, 20225). We excluded data more recent than October
2021 because they were incomplete. We determined the 5 leading causes of death
by year and age group, and compared the period March to December 2020 with the
period January to October 2021. Because the data are publicly available, the
study did not require institutional review board review.
Results
From March 2020 to October 2021, heart disease (20.1%),
cancer (17.5%), COVID-19 (12.2%), accidents (6.2%), and stroke (4.7%) were the
most common causes of death in the US. There were 2.875 million deaths in March
to December 2020 and 2.855 million deaths in January to October 2021; the 5
leading causes of death were the same in each year. Among those older than 1
year, the number of deaths increased across age groups.
Deaths from cancer, heart disease, and COVID-19 accounted
for the largest number of deaths in every group aged 55 years and older. The
leading 3 causes of death in these age groups were the same in 2020 and 2021.
Among people aged 85 years and older, COVID-19 was ranked as the second leading
cause of death in 2020 (110 000 deaths, 12.8% of deaths), and third in 2021
(69 000, 8.9% of deaths). Among those aged 45 to 54 years, COVID-19 was the
fourth leading cause of death in 2020 (17 000 deaths, 10.4% of deaths),
following heart disease, cancer, and accidents; in 2021, however, it was the
leading cause of death (30 000 deaths, 16.8% of deaths).
In both time periods, accidents accounted for the largest
number of deaths in every age group 1 to 44 years. Compared with 2020, COVID-19
increased from the fifth (6100 deaths) to the second leading cause of death
(13 000 deaths) among those aged 35 to 44 years in 2021, became the fourth
leading cause of death in 2021 among those aged 25 to 34 years (5000 deaths),
and those aged 15 to 24 years (1100 deaths).
Discussion
From March 2020 to October 2021, COVID-19 accounted for 1 in
8 deaths in the US and was a top 5 cause of death in every age group aged 15
years and older. Cancer and heart disease deaths exceeded COVID-19 deaths
overall and in most age groups, whereas accidents were the leading cause of
death among those aged 1 to 44 years. Compared with the 2020 time period,
deaths from COVID-19 in the 2021 time period decreased in ranking among those
aged 85 years or older but increased in ranking among those aged 15 to 54
years, and became the leading cause of death among those aged 45 to 54 years.
The pandemic also has had indirect effects on other causes
of death in the US. From 2019 to 2020, death rates increased for heart disease,
accidents, stroke, Alzheimer disease, and diabetes. Potential explanations are
fear of accessing health care or misattribution of COVID-19 deaths to other
causes. Accidental deaths (including drug overdoses and unintentional alcohol
poisoning), assault, and suicide remain major causes of death in the US,
particularly in younger age groups; the pandemic may have contributed to some
of these deaths.
