The disproportionate effect of covid-19 on ethnic minorities in some high income countries throws into sharp relief the effects of racism on health. On almost all health measures, ethnic minority groups, especially black and South Asian people, have the worst outcomes.123456 The covid-19 pandemic is just another example.7 This is a moral issue that has outraged civilised societies. As Alexandre Dumas wrote: “Moral wounds have this peculiarity—they may be hidden, but they never close; always painful, always ready to bleed when touched, they remain fresh and open in the heart.”
The effects of racism and social determinants of health are intertwined. Racism both shapes social determinants of health and has its own effect on the health of ethnic minorities. To understand race and health, we must understand the role of ethnicity and racism within modern societies. Everyday acts of interpersonal discrimination, implicit biases, cultural and structural racism will over time lead to worse health outcomes, including higher rates of chronic diseases and lower life expectancy.891011
Effect of covid-19 on ethnic minority groups
Covid-19 has disproportionately affected ethnic minority groups in developed countries. In the UK, people of black ethnicity have had the highest diagnosis rates, with the lowest rates observed in white British people.7 Data up to May 2020 show 25% of patients requiring intensive care support were of black or Asian background.12
According to a Public Health England report, the mortality risk from covid-19 among ethnic minority groups is twice that of white British patients after potential confounding factors such as age, sex, income, education, housing tenure, and area deprivation have been taken into account.7 Data from covid-19 inpatients in England showed that South Asian people had the highest death rates (350 deaths/1000 compared with 290/1000 for white people).13 Ethnic minority groups were also more likely to need intensive care and invasive ventilation than white patients despite similar disease severity on admission, similar duration of symptoms, and being younger with fewer comorbidities.13 Another study has shown a higher rate of covid-19 cases among ethnic minorities independent of comorbidities and socioeconomic risk factors.14
These differences are highlighted in the covid-19 cases among key workers. Although black and Asian staff represent only 21% of the NHS workforce, early analysis showed that they accounted for 63% of deaths among health and social care workers.15 This picture has also been reflected internationally. In the US, the case and admission rates are at least 2.5 and 4.5 times higher, respectively, among black, Hispanic, and Native American populations compared with white populations.16 The American Public Media Research Laboratory has estimated a death rate of 61.6/100 000 population for African Americans, 1.7 times greater than that of indigenous Americans and 2.3 times that of white and Asian Americans.17
Possible causes of ethnic disparities in health outcomes
Several potential reasons have been proposed, including higher rates of comorbidities (box 1) such as cardiovascular disease and diabetes in patients of South Asian ethnicity and hypertension in the black population.7
Causes of ethnic disparities in covid-19 outcomes
Structural (institutional) racism
Social determinants of health
Living in urban areas
Poor and overcrowded housing
High risk occupations
Higher burden of comorbidities (eg, cardiovascular disease and diabetes)
Ethnic minority groups are more likely to live in urban, overcrowded, and more deprived communities and to work in lower paid jobs, many of which carry a high risk of exposure to covid-19.718 Moreover, negative experiences within a culturally insensitive healthcare service may create barriers, inhibit access to healthcare, and influence healthcare seeking behaviours among ethnic minority groups.719 The UK government’s report on ethnic disparities in covid-19 states that some of the excess risk remains unexplained despite accounting for socioeconomic and geographical factors such as occupational exposure, population density, household composition, and pre-existing health conditions.20
A Public Health England report found that racism and discrimination may have contributed to the increased risk of exposure to and death from covid-19 among ethnic minority groups.19 Ethnic minorities have poorer access to healthcare and poor experiences of care and treatment21 related to racial discrimination and marginalisation.89101122 Additionally, ethnic minority staff in the NHS are less likely to speak up and raise their concerns about testing and personal protective equipment.23
However, ethnic disparities are not unique to covid-19 outcomes. Historically, marginalised ethnic groups have had higher rates and earlier onset of disease, more aggressive progression of disease, and poorer survival rates.6 Empirical analyses show that ethnic differences in health persist even after adjustment for socioeconomic status. In the UK, black women are five times more likely to die during pregnancy than white women24 and black people have a greater risk of detention under the Mental Health Act than white people.25 Research has also shown falling health in immigrant communities over time. For example, Mexican Americans and Mexican immigrants who had resided for 20 years or more in the US had a health profile similar to that of African Americans.26
Racism is a social construct that uses nationality, ethnicity, phenotypic, or other markers of social difference to maintain, capture, and justify the differential access to power and resources in society.27 It functions on multiple levels (box 2).9 Structural racism has the most deleterious effect on health. For example, a recent systematic review found that segregation was independently associated with late diagnosis and inferior survival rates in African Americans with lung or breast cancer.28 Although there are many forms of structural racism, residential segregation in the United States, including in its current form, is the most studied.
Definitions of racism9
An organised social system in which the dominant ethnic group, based on an ideology of inferiority, categorises and ranks people into social groups or “races” and uses its power to devalue, disempower, and differentially allocate valued societal resources and opportunities to groups defined as inferior
Structural (institutional) racism
The processes of racism that are embedded in laws (local, state, and federal), policies, and practices of society and its institutions that provide advantages to ethnic groups deemed as superior, while differentially oppressing, disadvantaging, or otherwise neglecting ethnic groups viewed as inferior
The instillation of the ideology of inferiority in the values, language, imagery, symbols, and unstated assumptions of the larger society
• Individuals and larger institutions, deliberately or without intent, treat ethnic groups differently, resulting in inequitable access to opportunities and resources (eg, employment, education, and medical care)
• Self-reported discrimination—an awareness of experiences of discrimination or bias that can adversely affect health, similar to other psychosocial stressors
Segregation affects health in multiple ways.9 Firstly, it is responsible for ethnic differences in socioeconomic status. A US study showed that the elimination of segregation would eliminate ethnic differences in income, education, and unemployment and reduce ethnic differences in single motherhood by two thirds.29 All of these stark differences are driven by access to opportunity at the neighbourhood level. Less than 5% of black children live in neighbourhoods with good resources. Segregation has also been related to access to poorer quality education and employment opportunities. Segregation can also adversely affect health because it creates communities with poor quality housing and neighbourhood environments. The concentration of poverty in these areas leads to exposure to higher levels of multiple chronic and acute psychosocial stressors, greater clustering of these stressors, greater exposure to undesirable social and physical environmental conditions, and reduced access to a broad range of resources that enhance health.
Although levels of segregation are steady or falling in the US, they are rising in Europe, where it is driven primarily by religion.30 In the UK, Bangladeshi and Pakistani people are the most segregated groups.30 National data from 2015 also show that socially stigmatised ethnic groups are over-represented in the most deprived neighbourhoods in England.3132 Just 9% of white British people live in the most deprived 10% of neighbourhoods compared with 31% of Pakistani, 28% of Bangladeshi, 20% of black African, and 18% of black Caribbean people.
Cultural racism is a reliance on stereotypes. This can give rise to unconscious bias and have a detrimental effect on health. A major report in the US found overwhelming evidence that black and other minority people routinely received poorer quality of care than white people.33 For example, a retrospective study of 139 Hispanic and white American patients assessed the provision of analgesia for patients with long bone fractures. White patients were twice as likely to receive analgesia than Hispanic patients, even after consideration of individual patient and clinician characteristics and the types of injury.34 More recent research documents these patterns across a broad range of outcomes35 and that higher implicit bias scores among physicians are associated with biased treatment recommendations for black patients.36 Implicit biases can also affect the quality of patient interaction and non-verbal behaviour. For example, one study found that physicians who scored high on implicit bias had poorer quality communication with their patients on both patient and objective ratings.37
Some ethnic minority patients may process the negative stereotypes in their culture by accepting them as true. This endorsement of these negative views is called “internalised racism” and has been associated with multiple health outcomes, including psychological distress and obesity in black populations.38
A recent review of 29 literature reviews and meta-analyses published between 2013 and 2019 found multiple associations between self-reported discrimination and health.39 As well as poor mental health (mental disorders, psychological distress, and lower levels of psychological wellbeing), self-reported discrimination is associated with incident disease (eg, diabetes, hypertension, breast cancer, cardiovascular outcomes) and preclinical indicators of disease (eg, coronary artery calcification, visceral fat, heart rate variation, and inflammation), poor health behaviours (eg, binge eating, smoking, and substance use), and lower use of healthcare services and adherence to medical regimens.39
One mechanism by which ethnic discrimination affects health is weathering—whereby exposure to discrimination as well as psychosocial, physical, and chemical stressors erodes health and accelerates biological ageing. For example, black women’s health deteriorates earlier than that of white women because of the constant stresses of their environment.40 Racism on a societal and individual level has both direct and indirect negative effects on health. It contributes to many of the causes of health disparities seen among ethnic groups.
Effect of racism on social determinants of health
An analysis of early data on covid-19 suggests that both its incidence and effect are distributed unequally, affecting those with material and social deprivation the most.41 The Marmot review in England shows that health inequalities have widened overall, life expectancy has stalled, and the amount of time people spend in poor health has increased over the past decade. The situation is much worse for ethnic minority groups, which have higher rates of deprivation and poorer health outcomes.424344454647 Relative poverty is also correlated with lower quality education and a higher rate of criminal activity, thus limiting employment opportunities.9 However, black Americans have a lower life expectancy than white and Hispanic Americans, even if they have attained university degrees.48
Interventions to ameliorate the adverse effect of covid-19 must start with reducing and reversing the socioeconomic effects (box 3). In the UK, socioeconomic inequalities were worsened by changes to the labour market, social security system, immigration policy, and insecure employment.49
Increase recognition and awareness of ethnic disparities in health and healthcare among the general public, key stakeholders, healthcare providers, and healthcare professionals
Governments and executive agencies should seek to understand why inequalities exist and how racism and structural discrimination affect people’s lives and contribute to ethnic disparities
Mandatory comprehensive data collection on ethnicity, through a health observatory or similar body, as part of routine health and social care delivery. Mandatory inclusion of ethnicity data at death certification
Provision of that data to local and national care providers to identify and tackle health problems faced by ethnic minorities
Development of legally binding, culturally competent, comprehensive occupational risk assessment tools that can be used to reduce the risk of employees’ exposure to and acquisition of covid-19
Provision of resources and support to businesses to ensure workplace safety, and financial support packages to ethnic minority individuals in low paid, insecure employment
Ethnic minority groups must be included in the extremely vulnerable category for covid-19 and where the risk is high, employees must be supported through flexible work environments such as non-public facing roles and redeployed away from covid-19 areas wherever possible
Improve access, experiences, and outcomes of health and social care by reducing variations around best practices. These include promoting equity of care through evidence-based guidelines and providing incentives to enhance patient-provider communication and trust. Regular health impact assessments, equity audits, and better representation of ethnic minority communities among staff
Increase the proportion of people from under-represented minorities among health professionals, removing barriers to their progression, including differential attainment in medical education and reform of assessment methods at undergraduate and postgraduate levels that are prone to ethnic bias. Increasing the representation of ethnic minorities in leadership at all levels
Reducing inequalities caused by socioeconomic factors that disproportionately affect ethnic minorities, and implementation of economic policies that tackle poverty, unemployment, and poor housing
Leadership on tackling institutional racism with a clear vision, accountability, and commitment for all organisations across public and private sectors. Inclusion of diversity as a key performance indicator for all leaders in their annual appraisal. Changes to policies and processes with mandatory programmes supported by organisational leadership and rigorously monitored
Fund and support research into the specific causes of disparities with the full participation of ethnic minority communities and development of programmes to reduce them
Fund, develop, and implement programmes for prevention and education on covid-19 in partnership with ethnic minority communities and accelerate health promotion and disease prevention programmes for non-communicable diseases, including promoting physical activity, smoking cessation, healthy weight, mental wellbeing and effective management of chronic conditions such as diabetes, hypertension, and asthma
In the UK, Public Health England should expand the Workforce Race Equality Standard to assess the effect of ethnic inequalities on health outcomes
Lack of information on ethnicity in UK health and social care data prevents an understanding of the extent of inequalities and disparities. In the US, New Zealand, and Australia, where such data are collected, they have revealed the multiple ways in which racism can adversely affect health and possible interventions to mitigate those effects. The NHS Race and Health Observatory in England was launched last year to investigate the effect of ethnicity on people’s health.50 The recent announcement that ethnicity is to be recorded as part of the death certification process is a major step forward.
Covid-19 should be seen in the wider context of ethnic disparities and not treated in isolation. The mitigation measures must redress the root causes of these disparities as well as the more urgent task of protecting those ethnic groups most at risk of adverse outcomes from covid-19 (box 3).
Tackling racism and discrimination
Systemic problems such as racism require structural interventions51 and reforms across the broad spectrum of society, including in healthcare, education, employment, and the criminal justice system. In the US, targeted civil rights policies in the 1960s-1970s narrowed the economic gap between black and white people, reduced health inequities, and improved living conditions and socioeconomic opportunities.52
High quality early childhood programmes can reduce crime, raise earnings, and promote education.53 In one such programme, the Carolina Abecedarian Project (ABC), people in the intervention group had lower levels of cardiovascular and metabolic diseases in their mid-30s compared with controls, with the effects particularly strong for men. Other interventions, including community initiatives to build community capacity around racism, have potential health benefits. Similarly, cultural empowerment such as a place for cultural activities among native communities in Canada reportedly resulted in substantially lower rates of youth suicide.54
Institutional interventions need concerted political and organisational leadership with funding and investment by the state. In the UK, despite successive reports and inquiries into ethnic disparities,444546 the recommendations of these inquiries have either not been implemented or have fallen by the wayside.
The focus of most interventions on cultural racism has been on reducing the implicit or unconscious bias and enhancing cultural competence. Cultural competency interventions can improve staff knowledge, skills, and attitudes and healthcare access and usage. However, there is little evidence that these interventions improve health outcomes or affect health equity.5556 Health and socioeconomic benefits have also been shown with values affirmation (enhancing self-worth by reflecting on and writing about most important values such as religious values or relationship with family and friendship) and social belonging interventions (creating a sense of relatedness).57
Changing policies and processes throughout organisations can reduce workplace discrimination.58 Research suggests that diversifying the healthcare workforce improves the performance of the entire healthcare system, and ethnic concordance between patient and a clinician has been associated with better health outcomes and higher levels of patient satisfaction.59 A broad range of affirmative action policies have been implemented over the past few decades to increase ethnic minority participation in higher education and senior roles.59 These programmes could be strengthened and supported further. The McGregor-Smith review in 2017 reported that people from ethnic minorities made up one in eight of the UK working age population but only 10% of the workforce and 6% of top management positions, with low employment (62.8%) and substantial underemployment (15.3%) compared with white workers.44 However, some early evidence suggests that the NHS Workforce Race Equality Standard initiative is increasing the number of ethnic minority staff in more senior positions.60
The tragedy of the covid-19 pandemic, recent events in the US, and the Black Lives Matter movement have brought into sharp focus the burning ethnic injustices in our societies. Many high income countries with legacies of slavery, imperialism, and colonialism have a moral duty to reckon with the past. We know the problems, and the solutions are mostly in front of us. We must act now.
Ethnic disparities in covid-19 are part of the historical trend of poorer health outcomes seen in marginalised ethnic groups
Ethnic inequities in health are not accounted for by socioeconomic status alone
Racism in its various forms is a fundamental cause and driver of ethnic differences in socioeconomic status, adverse health outcomes, and ethnic inequities in health
Mitigating the impact of covid-19 and other health inequities in ethnic populations requires a recognition of the causes, a commitment to openness and honesty, leadership, and resources
