Life expectancy in the United States plunged by nearly two years between 2018 and 2020, with the COVID-19 pandemic exacerbating a troubling trend dating back more than a decade, according to new findings published June 23

The study, co-authored by researchers at CU Boulder, Virginia Commonwealth University and the Urban Institute, found the drop was even greater among racial minorities, slipping 3.25 years among Black Americans and nearly four years among Hispanics, compared to 1.36 years among whites.

The overall U.S. decline was 8.5 times greater than that of the average decline among 16 other high-income countries during the same period.

鈥淲e were on a concerning trajectory relative to other countries for many years in terms of life expectancy, but the declines were only marginal,鈥� said co-author Ryan Masters, an assistant professor of sociology at CU Boulder鈥檚 Institute for Behavioral Science. 鈥淎long comes COVID and the effect on the U.S. population has been just atrocious.鈥�

Masters said an 鈥渙besogenic environment鈥� in which obesity, heart disease and other cardiometabolic disorders are rampant, was already leading the U.S. to lose ground with respect to health and survival. Inequities in access to health care and systemic racism have also played a role, he said.

When the pandemic hit, these existing factors鈥撯�搊n top of what the authors describe as a disorganized and disjointed response鈥撯�揷ombined to create a perfect storm of lives lost.

鈥淥ur Constitution delegates public health authority to states, so we had 50 response plans,鈥� said co-author Dr. Steven Woolf, director emeritus of VCU鈥檚 Center for Society and Health. 鈥淐OVID-19 exposed a lot of the systemic problems that have been fueling the long-term decline in the health of Americans.鈥�

Shorter lives for Americans

The BMJ study comes on the heels of a sweeping National Academy of Science report, published in May, documenting the suspected roots of a trend that began long before COVID.

After years of increases in life expectancy in the United States, those numbers flatlined in 2010 and declined slightly (about 0.1 years each year) from 2014 to 2017, marking the longest sustained decline since the influenza epidemic of 1918.

Masters, one of 12 scholars tapped to contribute to the report, said those declines resulted from two key trends: an increase in mortality among middle-aged and younger adults from drug- and alcohol-related deaths and suicide; and, more recently, an increase in death in older adults from things like heart disease and diabetes.

鈥淧eople in the United States used to have an advantage over other countries when it came to surviving to old age. That advantage is now gone and the gap is widening,鈥� Masters said.

To explore how the global pandemic influenced these trends, the researchers used death data from the National Center for Health Statistics to come up with age-, sex- and race-specific life expectancy in 2020.

When they compared it to life expectancy from 2010 to 2018 in the United States and in 16 wealthy peer countries, the results were stunning.

鈥淚t鈥檚 like nothing we have seen since World War II,鈥� said Woolf, noting that the U.S. hasn鈥檛 seen such a drop in life expectancy since 1943.

The declines among racial minorities particularly worry Masters.

After years of enjoying higher life expectancy than white men, Hispanic men saw that advantage wiped out in 2020.

Life expectancy in the U.S. Black male population in 2020 was 68, the lowest it has been since 1998.

鈥淚f this doesn鈥檛 bring shock and alarm to how poor the U.S. is doing in terms of population health, I don鈥檛 know what will,鈥� Masters said.

Younger people hit hard

In addition to high rates of death among racial minorities, the U.S. also saw an unusually high number of younger people die in 2020, with the majority of life expectancy lost among the male population due to deaths below age 65.

鈥淭his completely pushes back against the narrative that the pandemic is only affecting older populations,鈥� he said.

While some other peer countries, including Italy and Spain, saw losses in life expectancy, none were near the magnitude the U.S. saw and the bulk of deaths were among older people. Some countries, including New Zealand and Norway, saw life expectancy go up in 2020.

Masters notes the study did not look exclusively at deaths directly caused by COVID, a number that can be difficult to derive, but rather all deaths that occurred in 2020.

All-cause mortality in the United States increased by 23% in 2020. To date, more than 600,000 people have died of COVID, the most of any country in the world.

Masters said some of the same social inequities and health vulnerabilities that have plagued the U.S. for years likely left the U.S. more vulnerable to COVID.

For instance, people with heart disease, obesity or diabetes are more likely to be hospitalized or die from COVID. And lower-income, frontline workers are more likely to contract it.

As the virus slowly retreats in the United States, mortality rates will likely decline.

But Masters said he is not optimistic that life expectancy will rebound quickly.

鈥淯nfortunately, COVID is not just a respiratory disease, but also a vascular disease with potential ramifications for long-term health,鈥� he said.

He hopes the study will encourage policymakers to look big picture, not only at what could have been done differently in 2020 to save lives, but what must be changed long-term.

鈥淭his isn鈥檛 just a COVID problem,鈥� he said. 鈥淭here are broader social and economic policies that placed the United States at a disadvantage long before this pandemic. The time to address them is long overdue.鈥�
