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.”

Experts warn of high levels of chemicals in clothes by some fast-fashion retailers

Canadians who purchase cheap fast fashion from online retailers may be exposing themselves to potentially toxic chemicals.

A Marketplace investigation found that out of 38 samples of children’s, adult’s and maternity clothes and accessories, one in five items had elevated levels of chemicals — including lead, PFAS and phthalates — that experts found concerning. 

“People should be shocked,” said Miriam Diamond, an environmental chemist and professor at the University of Toronto. Diamond oversaw the lab testing that Marketplace commissioned.

Scientists found that a jacket for toddlers, purchased from Chinese retailer Shein, contained almost 20 times the amount of lead that Health Canada says is safe for children. A red purse, also purchased from Shein, had more than five times the threshold. 

“This is hazardous waste,” said Diamond.

“I’m alarmed because we’re buying what looks cute and fashionable on this incredibly short fashion cycle. What we’re doing today is to look [for] very short-lived enjoyment out of some articles of clothing that cost so much in terms of our … future health and environmental health. That cost is not worth it.”

Shein, which sells products both under its own brand and from third-party suppliers, sent an emailed statement to Marketplace saying it had removed the purse and jacket from its app, and would stop working with relevant suppliers until the issue was resolved. “We are committed to continuous improvement of our supply chain,” the company said.

Marketplace found garments containing elevated levels of chemicals from three fast-fashion retailers: Zaful, AliExpress and Shein. 

These companies boast hundreds to thousands of styles updated daily at rock-bottom prices. Tops are available for under $5, sneakers for under $10. Marketplace purchased a kids raincoat from AliExpress for just $6 US.

Miriam Diamond, a professor at the University of Toronto, oversaw the lab testing Marketplace commissioned to test for PFAS, heavy metals and phthalates in clothing. Here, she’s holding a purse from Shein that contained over five times the amount of lead that Health Canada considers safe in children’s products. (CBC)

Lead can cause damaging health effects to the brain, heart, kidneys and reproductive system. Children and pregnant people are more vulnerable, and infants and children are the most at risk, according to Health Canada’s website.

Lead is a naturally occurring element that can be found throughout the environment, but Joël Mertens, a product environmental impacts expert at the Sustainable Apparel Coalition, said the levels found in Marketplace’s lab results were beyond environmental contamination, or the small amounts clothes are exposed to unintentionally during the manufacturing process. 

“There were clearly products that were intentionally using lead and intentionally using it in a way that was well above what should be considered responsible  — or even safe,” he said.

Mertens explained that lead can be used in textile dye pigments, but there are safer alternatives that can achieve the same results.

Diamond pointed to the broader concerns stemming from the industry itself, noting that it’s not just the consumer that could be exposed to the ill effects of lead; it’s the entire supply chain, from mining the lead to shipping the final product. 

“If the final product isn’t safe for me, it’s definitely not safe for the workers that are handling these chemicals to make it,” said Diamond.

Health Canada would not give an interview, but in an emailed statement said it “monitors the marketplace and follows up on all identified consumer product risks.”

Expert: Current regulations on phthalates not strong enough in Canada

Other articles of clothing contained elevated levels of phthalates, a group of chemicals often used to make plastic more flexible. 

A clear tote purchased from Zaful contained enough phthalates, including DEHP, DiNP and DnOP, that Diamond and Mertens suggested Health Canada review the product.

Health Canada restricts some phthalates in children’s toys — like DEHP, DiNP and DnOP — to no more than 1,000 parts per million (ppm) each. However, it is unclear if it would be considered a children’s product. 

Health Canada has proposed to ban DEHP in all products bought and sold in Canada, but it is not yet in effect.  

Diamond said more attention should be paid to all phthalates, many of which are considered endocrine disruptors, which are chemicals that can interfere with hormones. They can also have developmental effects, and target the liver and kidneys, with particular concerns about its effect on people in their reproductive years, she said.

After notifying Zaful of the lab results, the company wrote in a statement that it is recalling the clear tote purse and sending customers who purchased it a refund.

In addition to the tote purse, Diamond flagged elevated levels of phthalates in a children’s tutu dress from Shein, a children’s dress featuring Elsa from the movie Frozen from AliExpress, the red purse purchased from Shein, a children’s raincoat set from AliExpress and a set of plastic bibs from AliExpress. None exceeded Health Canada’s limits.

But Diamond still has concern, particularly with the tendency for children to suck on clothing or put it in their mouths. Children’s skin also can absorb chemicals easier than adults’ skin, she said. 

After informing retailers of Marketplace’s investigation, Shein, Zaful and AliExpress removed all questionable products from their sites. The companies confirmed they would be investigating further, and taking action against suppliers and sellers if necessary.

Health Canada addressed the tote in an emailed statement, writing that the presence of phthalates doesn’t always mean a risk. The regulator suggested that unless a toddler under age four is sucking on the purse for more than three hours on a daily basis, the purse is not a significant source of exposure to phthalates.

Toxic chemicals found in some Shein, AliExpress and Zaful clothes

Some scientists are calling for stronger regulations on phthalates in Canada. Unlike the European Union, where the combined amount of phthalates is considered in regulations, Canada restricts each phthalate individually. 

“The question naturally arises that combined exposures are possible,” said Eva Pip, a biologist and professor at the University of Winnipeg. “You can’t have more than 1,000 [ppm] of any individual [phthalates] they list, but you could theoretically have 900 [ppm] of each of them together and still be okay.”

In 2021, Health Canada published a document stating that the combined exposure of phthalates to the Canadian environment is “below the levels that are expected to cause death to organisms.” 

Pip thinks this needs to change. “Given the fact that these chemicals are hormone and developmental disruptors, death [to organisms] is a pretty extreme criterion to determine harm,” she said.

Unnecessary forever chemicals found in rain gear

The scientists also tested for PFAS, a collection of fluorinated compounds commonly used in clothing for waterproofing and stain resistance. 

Many PFAS are known to be endocrine disruptors, and all are considered “forever chemicals” because they aren’t flushed from the body and don’t break down in the environment. 

Potential harmful effects include “increasing obesity to impairing immune function to different types of cancers to even diabetes,” Diamond said, noting: “This is a class of chemicals that should not be used unless they’re absolutely essential.” 

A raincoat purchased for $13.21 US from AliExpress contained high levels of PFAS, said Diamond. 

Health Canada prohibits the sale and import of any products containing particular fluorinated compounds, including the type CBC tested for, with the exception of products containing trace amounts of the chemical. However, the regulator doesn’t specify what a trace amount would be.

“This creates a huge loophole,” said Pip. “The manufacturer can claim that presence [of PFAS] in the product is incidental.” 

When reviewing the amount of PFAS found in the AliExpress raincoat, Pip said: “It is hard to imagine this is an incidental amount.”

When CBC brought the lab results to AliExpress, the company removed the raincoat from its online marketplace, confirming that it would be investigating further. 

A pink raincoat, purchased from AliExpress for $13.21 US, contained 220 parts per billion (ng/g) of PFAS, a type of ‘forever chemical’ that Diamond says should not be used in any product unless it is ‘absolutely essential.’ Experts considered this amount to be ‘high.’ (David Abrahams/CBC)

In addition to affecting human health, the chemicals assessed can enter the environment through laundering. A 2019 study from B.C.’s Ocean Wise found that up to 4.3 million microfibres can be shed in just one load of laundry. 

Mertens suggests PFAS are not essential, and there’s suitable alternatives easily available, such as wax for water repellency, or newer, degradable chemical compounds with similar effects.

“This is actually one of the areas that the industry has been focusing on, especially leading players in the industry, is phasing out PFAS compounds for alternatives,” said Mertens. 

Health Canada initially told Marketplace it has “identified concerns with PFAS and actively monitors the evolving science related to these substances.” With the products that concerned experts, the regulator confirmed it will “assess compliance and take immediate action as appropriate.” Ultimately though, the regulator said it is up to companies to provide safe products to Canadians. 

So you still need new clothes. Here’s what to do

Mertens says that while the fashion supply chain is complicated and spans many countries, the onus is on the brands themselves to oversee the process so it eliminates unnecessary chemicals.

“There are many, many organizations and groups out there that can help any brand or manufacturer navigate this space. Nobody really has an excuse to say, ‘Well, I just don’t know how to tackle it,’ including small brands.”

Mertens suggests consumers look for brands that complete product safety compliance through organizations like Oeko-Tex or Bluesign, which set restricted substances limits in each article of clothing based on progressive international regulations, like the EU’s REACH, which sets safe levels of certain chemicals in clothing.

And if you already own the garments? Diamond says some chemicals can wash out of clothes.

However, she adds, “In the long term, you know, I just don’t want to buy it.”
