Adverse social determinants of health linked to treatment-resistant hypertension in Black Americans

May 21, 2024
NIH-funded study suggests addressing these factors could reduce health disparities.

People were more likely to develop a type of treatment-resistant hypertension when they experienced adverse effects of economic and social conditions that influence individual and group differences in health status, known as social determinants of health.

Additionally, this risk was higher among Black American adults than white American adults, according to a study funded by the National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health.

Factors linked to this increased risk included having less than a high school education; a household income less than $35,000; not seeing a friend or relative in the past month; not having someone to care for them if ill or disabled; lack of health insurance; living in a disadvantaged neighborhood; and living in a state with low public health infrastructure. Apparent treatment-resistant hypertension is defined as the need to take three or more types of anti-high blood pressure medication daily and is associated with an increased risk for stroke, coronary heart disease, heart failure, and all-cause mortality.

Over a period of 9.5 years 24% of Black adults developed the condition compared with 15.9% of white adults. Exposure to adverse social determinants of health increased the risk in both Black and white adults, however, Black adults are more likely to face adverse social determinants of health. According to the researchers, addressing social determinants of health could reduce the racial disparities seen in apparent treatment-resistant hypertension and reduce the increased risk of stroke and heart attack in the Black American population.

For this study, scientists examined data on 2,257 Black and 2,774 white adults, who are part of a larger study that includes more than 30,000 Americans, of whom approximately half live in the “Stroke Belt” in the southeastern United States where the rate of stroke mortality is higher compared to the rest of the country.
