New Study Links Racism to Strokes in Black Women

The Study’s Findings

The Boston University study analyzed data from the Black Women’s Health Study, a long-term epidemiological study focused on understanding the health disparities faced by Black women. Participants were asked about their experiences with racism in various domains, including employment, housing, and interactions with the police. Researchers then tracked stroke occurrences over the study period.

After adjusting for factors such as age, education, and traditional risk factors for stroke, the study found a 38 percent increased risk of stroke among Black women who reported experiencing racism compared to those who did not. This finding suggests that racism acts as a significant independent risk factor for stroke, contributing to the already higher risk faced by Black women.

“The magnitude of the public health burden of the racial disparity in stroke is staggering,” George Howard, Dr.P.H., lead author and professor of biostatistics at the University of Alabama at Birmingham School of Public Health, previously told BlackDoctor.org. “We estimate that there were 22,384 additional stroke events in blacks occurring in 2014 above what would be expected relative to rates in whites.”

The Role of Stress and Inflammation

The researchers believe that the increased risk of stroke associated with racism is likely due to the chronic stress and inflammation it causes. Studies have shown that chronic stress can lead to elevated blood pressure, increased blood sugar levels, and damage to blood vessels, all of which are risk factors for stroke. Racism, as a persistent and pervasive form of social stress, can have a profound impact on the body’s physiological systems, increasing the risk of stroke and other health problems.

The Importance of Addressing Social Determinants of Health

This study highlights the importance of considering social determinants of health when addressing health disparities. Factors such as racism, socioeconomic status, and access to healthcare can have a significant impact on health outcomes. By addressing these social determinants, we can work towards reducing health disparities and improving the health of all individuals.

“We need more aggressive prevention efforts for stroke risk factors, particularly focusing on why blacks have more strokes,” said Howard. “Racial differences in the development and control of risk factors are to blame.” Pew Research reveals that 79 percent of Black Americans felt they had been discriminated against because of their race or ethnicity. 

The Need for Prevention and Intervention

The findings of this study underscore the urgent need for targeted prevention and intervention strategies to address the increased risk of stroke among Black women. This includes:

• Public health education campaigns: Raising awareness about the link between racism and stroke, and promoting healthy lifestyle behaviors that can reduce stroke risk.
• Addressing systemic racism: Addressing systemic racism in housing, employment, and the criminal justice system, which can help to reduce stress and improve health outcomes.
• Improving access to healthcare: Ensuring that Black women have access to quality healthcare, including regular screenings and preventive care.
• Developing culturally appropriate interventions: Developing stroke prevention programs that are culturally relevant and tailored to the needs of the Black community.

The Boston University study provides compelling evidence of the link between racism and stroke risk in Black women. This research highlights the importance of addressing social determinants of health and taking a comprehensive approach to stroke prevention. By working together to address these issues, we can help to reduce the burden of stroke and improve the health and well-being of Black women.
