Epidemiologist Sharrelle Barber discusses the racial inequalities that exist for COVID-19 and many other health conditions.
Throughout the COVID-19 pandemic, whether cases are flaring up, slowing to a simmer, or back on the rise in areas across the United States, the data makes one fact apparent: The viral disease has disproportionally sickened and killed marginalized communities. A New York Times analysis of data from almost 1,000 counties that reported racial breakdowns of COVID-19 cases and fatalities revealed that, compared to white Americans, African Americans and Hispanics were three times more likely to experience and two times more likely to die from the illness. The Navajo Nation has, per capita, more confirmed cases and deaths than any of the 50 states.
Many factors, like access to healthcare and testing, household size, or essential worker status, likely contribute to the pandemic’s outsized toll on communities of color, but experts see a common root: the far-reaching effects of systemic racism.
That racism would have such an insidious effect on health isn’t a revelation to social epidemiologists. For decades, public health experts have discussed “weathering,” or the toll that repeated stressors experienced by people of color take on their health. Studies have demonstrated the link between such chronic stress and high blood pressure, the increased maternal mortality rate among black and indigenous women, and the elevated prevalence of diabetes in black, Latino and especially Native American populations. The pandemic has laid bare these inequities. At the same time, outcry over systemic racism and police brutality against African Americans has roiled the nation, and the phrase, “Racism is a public health issue” has become an internet refrain.
What exactly is the nebulous concept of “public health”? According to Sharrelle Barber, a Drexel University assistant professor of epidemiology, the concept goes beyond the healthcare setting to take a more holistic look at health in different populations. “The charge of public health,” Barber told Smithsonian, “is really to prevent disease, prevent death, and you prevent those things by having a proper diagnosis of why certain groups might have higher rates of mortality, higher rates of morbidity, et cetera.”
Below is a lightly edited transcript of Smithsonian’s conversation with Barber, who studies how anti-black racism impacts health, about the many ways in which racism is a public health crisis:
When people say, “Racism is a public health problem,” what, in broad strokes, do they mean?
We’ve been observing racial inequities in health for decades in this country. W.E.B. DuBois, who was a sociologist, in The Philadelphia Negro showed mortality rates by race and where people lived in the city of Philadelphia at the turn of the 20th century and found striking inequalities based on race. Fast forward to 1985, 35 years ago, and we have the [Department of Health and Human Services-sponsored] Heckler Report, one of the most comprehensive studies the country had undertaken, which again found striking inequalities across a wide range of health outcomes: infant mortality, cancer, stroke, et cetera.
There are various explanations for why these racial inequalities exist, and a lot of those have erroneously focused on either biology or genetics or behavioral aspects, but it’s important to examine the root causes of those inequities, which is structural racism…Racism is a public health problem, meaning racism is at the root of the inequities in health that we see, particularly for blacks in this country. So whether it’s housing, criminal justice, education, wealth, economic opportunities, healthcare, all of these interlocking systems of racism really are the main fundamental drivers of the racial inequities that we see among black Americans.
What are some specific factors or policies that have set the foundations for these health inequities?
Any conversation about racial inequities has to start with a conversation about slavery. We have to go back 400-plus years and really recognize the ways in which the enslavement of African people and people of African descent is the initial insult that set up the system of racism within this country. One of the major drivers that I actually study is the link between racial residential segregation, particularly in our large urban areas, and health inequities. Racial residential segregation is rooted in racist policies that date back at least to the 1930s. Practices such as redlining, which devalued black communities and led to the disinvestment in black communities, were then propped up by practices and policies at the local, the state and federal level, for example, things like restrictive covenants, where blacks were not allowed to move into certain communities; racial terror, where blacks were literally intimidated and run out of white communities when they tried to or attempted to move into better communities; and so many other policies. Even when you get the 1968 Fair Housing Act, the system finds a way to reinvent itself to still perpetuate and maintain racism.
Within segregated communities, you have so many adverse exposures, like poor quality housing or lack of access to affordable, healthy foods, lack of access to quality healthcare, and the list goes on. The chronic stressors within these communities are compounded in segregated communities, which then can lead to a wide array of health outcomes that are detrimental. So for example, in the city of Philadelphia, there’s been work that has shown upwards of a 15-year life expectancy difference between racially and economically segregated communities, black communities and wealthier white communities.
I imagine that sometimes you might get pushback from people who ask about whether you can separate the effects of socioeconomic status and race in these differences in health outcomes.
Yeah, that’s a false dichotomy in some ways. Racism does lead to, in many aspects, lower income, education, wealth. So they’re inextricably linked. However, racism as a system goes beyond socioeconomic status. If we look at what we see in terms of racial inequities in maternal mortality for black women, they are three times times more likely to die compared to white women. This disparity or this inequity is actually seen for black women who have a college degree or more. The disparity is wide, even when you control for socioeconomic status.
Let’s talk about the COVID-19 pandemic. How does racism shape the current health crisis?
The COVID-19 pandemic has literally just exposed what me and so many of my colleagues have known for decades, but it just puts it in such sharp focus. When you see the disproportionate impact COVID-19 is having, particularly for blacks, but also we’re seeing emerging data on Indigenous folks, it is just laying bare the ways racism is operating in this moment to produce those inequities.
Essential workers who had to continue to work during periods of stay at home orders across the country were disproportionately black and Latino. These are also often low wage workers. They weren’t given personal protective equipment, paid sick leave, hazard pay, and really had to choose between being exposed and protecting themselves and having an income during this period. So that’s one way racism operates.
Then we know that those individuals aren’t isolated, that they return to homes that often are crowded because of the lack of affordable housing. Again, another system of racism that compounds the effect. Then you think about places like Flint, Michigan, or places that don’t have access to clean water. When we were telling people, “Wash your hands, social distance,” all of those things, there were people who literally could not adhere to those basic public health prevention measures and still can’t.
