New Delhi, Feb 21: Long before a patient walks into a clinic or meets a doctor, their health trajectory may already be shaped by where they live, the schools they attend, the air they breathe and the policies that govern their communities, according to a sweeping global review of research on structural racism.
The study, which analysed findings from 1,416 research papers across countries and decades, concludes that structural racism remains one of the most powerful — yet often invisible — drivers of health inequality worldwide.
Rather than focusing on individual prejudice, the research points to systemic inequities embedded in housing, education, employment, criminal justice and healthcare systems. These inequities, researchers say, consistently translate into higher mortality rates, greater disease burden and poorer birth outcomes among racialised and marginalised communities.
The pattern is strikingly consistent across geographies: it is systems, not individual behaviour, that largely drive health gaps.
Inequality built into systems.
The review found that discriminatory housing policies, neighbourhood disinvestment and environmental exposure are directly linked to higher rates of asthma, stroke and cancer mortality. Communities living in under-resourced neighbourhoods often face compounded risks — from pollution to limited access to quality healthcare — that accumulate over a lifetime.
Within healthcare systems themselves, racially minoritised patients were found to be more likely to receive inadequate pain management, face delays in diagnosis and encounter subtle forms of dismissal or disrespect. Over time, such experiences contribute to chronic stress, mistrust in institutions and poorer health outcomes.
Even when clinical needs are similar, disparities persist. Access to life-saving treatments such as organ transplants remains uneven, and women of colour in several countries continue to experience delayed diagnoses and undertreatment for serious illnesses, including cancer.
Researchers note that the erosion of trust in healthcare systems is not only a social issue but also a measurable health risk in itself.
Inequality before birth The review highlights maternal and infant health as among the clearest indicators of structural inequity.
In the United States, Black mothers die from pregnancy-related causes at roughly three times the rate of white mothers, even when income and education levels are comparable.
In the United Kingdom, South Asian and Black women face significantly higher rates of preterm birth. Similar patterns have been observed elsewhere, including reports of institutionalised separation practices in maternity wards in Israel affecting Palestinian-Arab mothers.
Across settings, women living in socio-economically disadvantaged neighbourhoods face sharply higher risks of severe pregnancy complications. Researchers say these outcomes reflect broader social structures — including housing, economic inequality and policing — that are deeply intertwined with maternal and infant survival.
A global public health issue Although a large share of studies originate from the United States, the review underscores that structural racism is a global phenomenon.
In Brazil, Black, Biracial and Indigenous communities experienced disproportionately high COVID-19 mortality, linked to underfunded health facilities and geographic exclusion. In Canada and parts of Europe, racialised and ethnic minority populations have reported barriers to diagnosis, treatment and culturally responsive care.
Despite differing cultural contexts, the underlying dynamic is similar: racial hierarchies embedded within social systems shape unequal access to opportunity and, ultimately, unequal health outcomes.
Health and policy are inseparable The authors argue that health inequity cannot be separated from politics and public policy. Addressing disparities, they say, requires reforms that extend well beyond hospitals and clinics.
Among the priorities outlined are policy-level interventions targeting systemic discrimination, integration of health goals with housing and education reform, expanding research in low- and middle-income countries, and embedding intersectional approaches that consider how race intersects with gender, class and sexuality.
They also call for greater accountability through transparent data reporting and equity audits. Ignoring structural racism, the review warns, carries a heavy cost — not only in lives lost, but in weakened economies, eroded public trust and intergenerational trauma.
The central message is clear: lasting improvements in public health depend not only on medical advances, but on dismantling the systems that quietly determine who has the chance to live a long and healthy life.
