Racism and discrimination are public health threats, experts warn

A recent series of papers published in The Lancet explores the ways in which racism impacts the physical and mental health of people all over the world, and the mechanisms by which it does so. The COVID-19 pandemic exposed many of these inequities, and may even have exacerbated them.

When acknowledging the impact racism can have on health, it is important to remember that less than a century ago racist ideas were given legitimacy by scientific and medical communities in Western countries.

While Charles Darwin is held up as a symbol of rationality and scientific progress, it is important to note that his theory of evolution by natural selection in the Origin of Species published in 1849, was appropriated by eugenicists.

Eugenicists argued for the selective breeding of humans with the aim of improving the heritable traits in a population.

Originally, these ideas claimed that people on low incomes had lower mental capabilities and morals, and that preventing these people from being able to reproduce would prevent these traits from being passed on, allegedly improving the human gene pool.

These ideas were quickly applied to preexisting ideas of racial categories of humans, with impacts on the health of people of different racial and ethnic backgrounds, which we are still seeing today.

This is just one of the topics highlighted in a recent series of papers published in The Lancet, which explores the role racism has played in health outcomes globally.

Written by a group of scientists at University College London in the United Kingdom, the papers explore the different ways in which racist ideas and practices have infiltrated science and medicine and caused harm. Racism, they state, is a threat to public health.

To drive the point home, the authors explain that their own workplace, University College London, was once the home of “racist pioneers” Francis Galton and Karl Pearson, whose work started to document human differences in an attempt to categorize certain traits.

Some scientists and theorists have applied these ideas to the concept of humans belonging to different races that had existed for over 100 years prior to that, which had been used to uphold first colonialism by Europe of other countries, and then neocolonialism.

The series of articles goes on to provide numerous examples of people being mistreated by doctors and scientists for racist and xenophobic reasons, from the Tuskegee Study of Untreated Syphilis in Black men, through to more recent COVID-19 vaccine inequity.

It also explores the reasons why scientists worldwide upheld the notion of “othering” some groups for so long, and why they were able to do so for so long.

When asked by Medical News Today why the series was being published now, lead author Prof. Delanjathan Devakumar, professor of global child health and honorary consultant in public health at University College London told us in an email that there was no particular reason to publish the series now, as the problem is long-existing and ongoing.

He said:

“The simple answer is that it does not need to be now. We have always had racism. But there have been changes in the last decade or so, with the rise of populist and divisive politics around the world that scapegoats groups and can lead to real and sometimes devastating consequences.”

The COVID-19 pandemic both exacerbated and revealed much of the divisive politics that define our era, as well as the inequities racist politics can cause.

Black, Hispanic, Asian, American Indian, and Pacific Islander people have been disproportionately more likely to become infected with SARS-CoV-2, or die from the infection in the United States to date. This trend continued globally.

These differences were picked up quickly, and research into their causes was initially inconclusive. While socioeconomic factors and comorbidities explained some of the differences in infection and death rates that were observed, they did not explain all of them, and theories abounded.

One of the most contentious theories that arose initially blamed skin color, claiming that vitamin D deficiencies were to blame for the higher infection and death rate in people of color living in areas where deficiency was prevalent among these groups. This notion has since been disproven.

One doctor who carried out research in the earlier days of the pandemic into these racial inequities was Prof. Ladan Golestah, a professor of nephrology at the Albert Einstein College of Medicine working in the Bronx during the first surge of COVID-19, in the spring of 2020.

She told MNT in an interview: “I think we were kind of struck by how overwhelmingly it kind of […] took over all of our realities. And I think part of the problem was there was so much death, honestly […] So many bad outcomes [resulted] out of that initial COVID surge that we were, we felt, powerless.”

She, along with her colleagues decided to use the data they had available to try to “lay bare what was happening and what was behind it.”

Their research eventually appeared in eClinical Medicine, and showed that all-cause mortality rates were 60{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} higher for Black people than white people during the first COVID-19 surge, and this was “incompletely explained by age, multiple reported comorbidities and available metrics of sociodemographic disparity.”

Looking back, she says she realized what was “hidden in plain sight” was the scale of undiagnosed comorbidity which led to much worse health outcomes for Black people.

This was due to a lack of access to healthcare due to the financial barriers which were disproportionately experienced by this group.

COVID-19 had in turn resulted in more trauma, and physical damage to these groups of people, further exacerbating those inequities. The introduction of telemedicine also exacerbated some groups’ ability to access healthcare, she explained.

However, even where some financial barriers to healthcare access were removed, for example for National Health Service (NHS) patients in the U.K., the COVID-19 pandemic revealed other barriers.

In the U.K., People’s COVID Inquiry, run via the NHS campaign Keep Our NHS Public, heard back in March 2021 that the initial responses to COVID-19 infection in people of color were inadequate.

Lobby Anikola, of the COVID-19 Bereaved Families for Justice group, told the People’s COVID Inquiry — 57 minutes into the video — that “there were many inequalities that people were already aware of, and now these inequalities are costing the lives of people of color.”

“There is also the concern of how appropriate [and] how able the medical service are to diagnose and treat medical conditions in Black bodies,” says Anikola.

In his statement, he points out that when calling emergency helplines during the first wave of COVID-19, people were asked if they had “blue lips,” a symptom of lack of oxygen in the blood in white people, but one that is less obvious in people with darker skin, meaning that many remained at home when they needed to seek urgent medical treatment.

Pulse oximeters had also been shown to fail to pick up hypoxia in people with darker skin, as they had been designed for use on white people, a study published in BMJ showed.

The COVID-19 pandemic is a global issue, and the inequities have not just been felt by people of different ethnic and racial backgrounds who live in the U.S. or Europe, but also by individuals living in low- and middle-income countries.

While the health systems of wealthy countries had been overwhelmed by the first wave of COVID-19, their wealth meant they were much better placed to design, develop and make vaccines to target the SARS-CoV-2 virus.

Large-scale vaccine campaigns took place in the U.S. and Europe, but low- and middle-income countries were left behind.

In 2021, the World Health Organization (WHO) set a target for 70{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} global vaccination coverage by mid-2022. As of June 2022, only 58 of WHO’s 194 member states had achieved this, and just 37{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} of healthcare workers had received a complete course of primary vaccination in low-income countries.

“There was hoarding by the North American and Western European countries,” Dr. Peter Hotez, co-director of the Center for Vaccine Development at Texas Children’s Hospital, told MNT.

“That was one issue. The second issue was there was an upstream science policy failure, providing too much emphasis on speed and innovation, and not enough downstream to be able to make vaccines locally in low and middle-income countries,” he noted.

The world had “paid heavily” for this mistake, as it opened the door for new virus variants to emerge, he argued.

“Delta arose out of an unvaccinated population [in] early 2021. And then Omicron — it emerged from an under-vaccinated population in Africa, later in 2021. And so it got into this mess that we’re in today. So, vaccine equity is not simply a question of equity, [it] is fundamental to pandemic control,” explained Dr. Hotez.

Not all was lost however, he said, as there is now an opportunity to ensure that vaccine equity is achieved for low- and middle-income countries for vaccines for emerging variants, he suggested.

He is not the only one to point to potential opportunities to improve the situation. While health inequities due to race, xenophobia, and colonialism are stark, some feel the recent focus on the issue has highlighted areas where improvements could be made.

Dr. Golestah said:

“On a more hopeful note, I think, you know, having reckoned […], as a society, with COVID-19, and with those things, and seen them I think we are in a better position. I can build on that, […] try and build on that recognition, and design our health systems to become more equitable, and as a result, better for everyone.”

The Lancet series itself argues that if policy based on racist structures got us into the current situation, then appropriate, well-designed health policy could get us out of it, and eventually remove racial health inequities.

As Dr. Hotez added: “Remember, COVID-19 is our third major coronavirus pandemic of the 21st century, we’ve had SARS and MERS. And now COVID-19.” Other epidemics or pandemics may emerge soon, he believes.

In this context, “[w]hat we really need to address is equity, and not only to have equity but recognize that it’s essential to global public health preparedness,” said Dr. Hotez.

“I mean, often it’s framed purely as humanitarian grounds, which of course, is important in our motivations at our labs. But it’s not only a humanitarian gesture, it’s far more than that it’s front and center of pandemic preparedness.”

The impact of racial discrimination and income

  • Researchers have observed higher COVID-19-related hospitalization and mortality rates among racially minoritized groups and people with lower incomes.
  • A recent review describes how high poverty rates and racial discrimination led to these disparities in COVID-19-related health outcomes.
  • Preexisting medical conditions are more prevalent in individuals with a lower income and those who belong to historically marginalized groups, making them more susceptible to the negative health effects of COVID-19.
  • Factors associated with high poverty rates and racial discrimination, such as limited access to healthcare, residential segregation, overcrowding, poor housing conditions, and high risk work conditions, have also contributed to the disparities in COVID-19-related health outcomes.

The health effects of COVID-19 have disproportionately affected individuals belonging to low income and racially or ethnically minoritized groups. Studies have shown a higher number of COVID-19 cases, hospitalizations, and deaths among individuals belonging to Indigenous, Black, and Hispanic communities. Similarly, evidence suggests a higher risk of severe disease and mortality among individuals with lower incomes.

Early in the pandemic, the factors associated with the higher rates of hospitalization and mortality among these groups were not well-understood. In other words, it was unclear whether comorbidities, social determinants, or both contributed to these worse COVID-19-related health outcomes.

One study, for example, which researchers conducted early in the pandemic, found that both comorbidities and social factors likely contributed to the higher mortality in the Black patient populations.

Dr. Ladan Golestaneh, professor of medicine at the Albert Einstein College of Medicine in New York City and the study’s lead author, told Medical News Today:

“Our study did a careful analysis of the population of the Bronx who receives their care at our health system — a health system that has invested heavily in programs that serve our community of patients.[…]. We were able to show that despite adjustment for multiple comorbidities and risk factors — including area-level poverty and use of public transportation — hospitalized Black patients died at disproportionately higher rates than did white patients.”

Noting the role of social determinants, as the study suggests, Dr. Golestaneh said, “The worse severity of illness and mortality outcomes seen in racial/ethnic minorities have to do with low socioeconomic status, barriers to adequate high quality healthcare, and residential racial segregation, the latter resulting from a deliberate historical act by the U.S. government to separate residential communities by race and disinvest from Black residential communities.”

A recent review in The Lancet Regional Health — Americas now summarizes evidence delineating the underlying factors responsible for the more profound health consequences of COVID-19 in people belonging to lower income households or racially or ethnically minoritized groups.

Poverty levels were relatively high in the United States before the pandemic. Various factors, such as weak labor protections and an inadequate welfare state, enabled these high poverty rates.

Moreover, racial and economic inequalities tend to be interlinked and can be difficult to disentangle. Racial discrimination has had a significant impact on social welfare policies and labor laws in the U.S. Racial discrimination also influences educational and employment outcomes.

Thus, the systemic nature of racism has resulted in higher poverty rates for the targeted individuals. The 2019 Supplemental Poverty Measure published by the Census Bureau reported that the poverty rates among Black and Hispanic residents were more than 18{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} in the United States, whereas 8.2{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} of non-Hispanic white residents met the criteria for living in poverty.

Given the close association between race and poverty, the authors of the present review considered how these interconnected factors increased vulnerability to COVID-19-related health consequences.

Preexisting health conditions, such as cardiovascular disease, diabetes, cancer, and HIV, are more prevalent among individuals belonging to historically marginalized groups and those with low socioeconomic status. These preexisting conditions can worsen the effects of a SARS-CoV-2 infection, resulting in a higher number of hospitalizations and deaths.

Another closely related reason for the worse outcomes is limited access to healthcare.

Individuals belonging to low income and historically marginalized communities are less likely to have health insurance than higher income and white populations, respectively.

A 2020 study reported that 18.2 million individuals at high risk of COVID-19 due to older age and underlying conditions were uninsured or lacked adequate insurance. Notably, the study found that people with lower incomes and racially minoritized individuals were more likely to belong to this group of high risk uninsured or underinsured individuals.

State policy decisions have also contributed to the high number of underinsured individuals. For instance, 12 states have refused the expansion of Medicaid, which would extend coverage to individuals with incomes of up to 138{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} of the Federal Poverty Level. This has especially influenced the ability of low income marginalized groups to access healthcare.

Besides the high cost of healthcare, other obstacles hindering access to healthcare for these groups include the “earned” mistrust of healthcare institutions and clinicians, language barriers, and biases in the healthcare system.

These factors have also contributed to the low rate of vaccination in marginalized communities, especially during the initial period of the vaccine rollout. Distrust of the healthcare system due to historical reasons and recent experiences of racial discrimination in healthcare settings have led to vaccine hesitancy.

Healthcare professionals can play a vital role as trustworthy sources of information on vaccinations. However, the lack of adequate health insurance has limited access to these professionals, thus contributing to lower vaccination rates.

Residential segregation by race and socioeconomic status remains prevalent in the U.S. and is associated with racial disparities in health outcomes.

Studies suggest a similar impact of residential segregation on COVID-19 outcomes, with a higher number of COVID-19 deaths occurring in racially and socioeconomically segregated counties.

Other studies have investigated the role of housing quality in mediating the COVID-19-related health disparities.

Evidence suggests that housing quality factors, such as overcrowding and incomplete indoor plumbing, are associated with higher COVID-19 cases and death rates.

Overcrowding and multiple generations residing together are more prevalent in historically marginalized and low income households.

These housing quality factors facilitating the rapid spread of SARS-CoV-2 have contributed to the disproportionate impact of COVID-19 on low income and racially minoritized groups.

These individuals are also more likely to rent than own a home. The eviction of renters during the pandemic also resulted in a surge in COVID-19 cases among those displaced.

Residential location can also influence access to COVID-19 testing and vaccination and, subsequently, vulnerability to COVID-related health consequences. For instance, states with a larger Black population and higher poverty rates had lower SARS-CoV-2 testing rates.

Similarly, a study covering 94 counties found that Black individuals were more likely to have to travel more than 10 miles to the vaccination site than their white counterparts. Lack of transportation or access to the internet to schedule a vaccination appointment may also have contributed to the lower vaccination rates.

Another reason for the higher levels of severe COVID-19 cases among people with a lower income and racially and ethnically minoritized individuals includes employment in occupations associated with a high risk of SARS-CoV-2 infection.

Individuals from low income households constitute a significant proportion of essential workers, who are involved in vital sectors, such as healthcare, retail, education, food production, and transportation. Individuals earning less than twice the federal poverty levels constitute nearly 25{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} of essential workers.

Similarly, individuals belonging to historically marginalized groups often make up a substantial share of workers in essential occupations. For example, 3 in 4 frontline workers in New York City belong to these groups.

The contagiousness of SARS-CoV-2 and the inability to work remotely meant that essential workers were at increased risk of contracting COVID-19. Moreover, the lack of adequate safety and health measures, such as the limited availability of personal protective equipment and difficulty enforcing physical distancing regulations at the workplace, further increased the risk of exposure to SARS-CoV-2.

The lack of access to paid leave or unemployment benefits also contributed to the increased vulnerability of essential workers to a SARS-CoV-2 infection.

Another contributing factor was lower vaccination rates, potentially due in part to a lack of flexibility in work schedules and unavailability of paid leave during the early phase of the vaccine rollout.

The studies that the review summarizes show how racial discrimination and high poverty rates have resulted in the disparities in the health consequences of COVID-19. Describing the impact of these structural inequities, Dr. Cary Gross, professor of medicine and epidemiology at Yale University, noted to MNT: “The COVID-19 pandemic has laid bare a hard truth about American society at large and the healthcare system in particular.”

“We see large health inequities across race and ethnic groups not because of a single shock to the system (COVID-19) but because of the very nature of the system itself — it is working exactly as designed. There is an entrenched hierarchy in which racism leads not only to differential wealth, but also differential power, prestige, and freedom. So differences across race groups in wealth and poverty are vital, but they don’t tell the whole story.”

– Dr. Gross

The review authors noted that research on the effects of COVID-19 on individuals with disabilities, members of LGBTQIA+ communities, and American Indian and Alaska Native individuals remains limited. These individuals are also often socioeconomically disadvantaged and thus may be at increased risk of negative health effects associated with COVID-19.

Although the median household income of Asian American households is higher than that of all U.S. households, there are considerable disparities in income levels within the Asian American community. For instance, individuals in the top 10{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} of earners in the Asian community have 10.7 times the income of those in the bottom 10{cfdf3f5372635aeb15fd3e2aecc7cb5d7150695e02bd72e0a44f1581164ad809} of earners.

Hence, more research is necessary to investigate whether vulnerability to COVID-19-related health consequences was more pronounced in Asian Americans with a low income.
