UK Stroke Rates Rebound After Decades of Decline, Driven by Widening Ethnic and Socioeconomic Inequalities

Stroke incidence in the United Kingdom has reversed decades of progress and begun climbing again, fueled by widening health inequalities that fall most heavily on Black African and Black Caribbean communities, according to a major 30-year analysis unveiled at the European Stroke Organisation Conference (ESOC 2026). The findings mark a worrying reversal in one of public health's most celebrated long-term success stories: after falling 34 percent between 1995–1999 and 2010–2014, stroke risk has surged 13 percent in the period from 2020 to 2024. Researchers say the rebound reflects a collision of interconnected factors, including unequal access to preventive care, large gaps in early detection of risk factors among minority communities, and the lingering disruption of the COVID-19 pandemic on primary health services.

The Details

The research, presented in Maastricht, Netherlands, at ESOC 2026 from 6 to 8 May 2026, draws on the South London Stroke Register — one of the longest-running population-based stroke registers in the world. The analysis has tracked 7,726 strokes among a population of 333,000 people in an ethnically diverse area of South London since 1995. The register recruits every person with a first-ever stroke within its geographically defined area, including people who may never reach specialist care.

In the most recent period, 2020–2024, stroke incidence was more than twice as high in Black African populations as in the white population, with an incidence rate ratio of 2.31 (95% confidence interval 2.03–2.62). Black Caribbean populations also faced substantially elevated risk, recording an incidence rate ratio of 2.0 (95% CI 1.73–2.31) compared with white participants.

The inequalities were most pronounced for intracranial haemorrhage (ICH), a particularly severe subtype of stroke. Dr Camila Pantoja-Ruiz, the lead researcher at King's College London, explained the divergence: compared with other stroke types, intracerebral haemorrhage is more strongly associated with uncontrolled high blood pressure, which is more common in Black communities.

Context

Underlying the disparity are stark differences in the prevalence of major risk factors. Black African participants had 47 percent higher prevalence of high blood pressure and 92 percent higher prevalence of diabetes than white participants. Among Black Caribbean participants, the gaps were 29 percent higher prevalence of high blood pressure and 123 percent higher prevalence of diabetes. These conditions are primary drivers of stroke and are often manageable with early detection, sustained treatment, and consistent monitoring.

Yet early detection appears to be failing some of the highest-risk patients. Twelve percent of Black African patients had no diagnosed risk factors prior to their stroke, compared with 6.3 percent of white patients. That nearly two-fold gap points to substantial under-detection of risk factors in primary care for a significant proportion of the population most at risk.

The burden also falls earlier in life. Black African populations in the study experienced stroke approximately 10 to 12 years earlier than white populations, on average.

After a stroke, the gap in care persists. Black African stroke survivors had 34 percent lower odds of receiving timely follow-up care. Dr Camila Pantoja-Ruiz, lead researcher at King's College London, noted that the period immediately after a stroke is critical for preventing another one. Interventions such as controlling blood pressure, optimising medication, and identifying other vascular risks are essential during this window. She added that less timely follow-up leaves patients at elevated risk for longer, and that this disparity may be influenced by mistrust in healthcare services linked to historical and ongoing experiences of discrimination.

Dr Camila Pantoja-Ruiz also pointed to the lasting impact of the COVID-19 pandemic as a partial driver of the recent increase. The pandemic reduced access to primary care, blood pressure monitoring, and prescribing, with effects that were felt more acutely in Black and deprived communities. Disruptions to routine healthcare during the pandemic have been documented across many countries, and the register data indicate that the consequences for stroke prevention in already disadvantaged populations have been particularly pronounced.

Beyond the pandemic, structural factors loom large. Dr Camila Pantoja-Ruiz said these patterns of increased stroke risk may also be influenced by broader factors, including racism, unconscious bias, and socioeconomic circumstances, which can impact access to and quality of care.

What's Next

The findings underscore the need for stroke prevention and post-stroke care designed with equity at their center. Health systems will need to address the upstream drivers of risk identified in the study — earlier and more equitable detection of high blood pressure and diabetes, improved trust in follow-up services, and policies that close the socioeconomic gaps in access to care. The pandemic exposed and deepened fractures in primary care that had been narrowing for years; reversing the 13 percent rise in stroke incidence will require sustained attention to the communities now bearing the greatest burden. The South London Stroke Register continues to track every first-ever stroke in its defined geographical area, offering a long-term lens on whether policy and clinical responses can restore the downward trend that prevailed for nearly two decades.
