Concerning trend of growing subarachnoid hemorrhage rates in Black people
Results of a new study based on hospital discharge data show Black people have disproportionately high rates of SAH versus other racial groups. Compared with White and Hispanic people, who had an average of 10 cases per 100,000, or Asian people, with 8 per 100,000 people, Black people had an average of 15 cases per 100,000 population.
Whereas case rates held steady for other racial groups in the study over a 10-year period, Black people were the only racial group for whom SAH incidence increased over time, at a rate of 1.8% per year.
“Root causes of the higher SAH incidence in Black [people] are complex and likely extend beyond simple differences in risk factor characteristics to other socioeconomic factors including level of education, poverty level, lack of insurance, access to quality care, and structural racism,” study investigator Fadar Oliver Otite, MD, assistant professor of neurology at SUNY Upstate Medical University, Syracuse, said in an interview.
“Addressing this racial disparity will require multidisciplinary factors targeted not just at subarachnoid hemorrhage risk factors but also at socioeconomic equity,” he added.
The study was published online in Neurology.
Uncontrolled hypertension
The average incidence of SAH for all participants was 11 cases per 100,000 people. Men had an average rate of 10 cases and women an average rate of 13 cases per 100,000.
As expected, incidence increased with age: For middle-aged men, the average was four cases per 100,000 people whereas for men 65 and older, the average was 22 cases.
Dr. Otite and his team combined U.S. Census data with two state hospitalization databases in New York and Florida and found that there were nearly 40,000 people hospitalized for SAH between 2007 and 2017. To find annual incidences of SAH per 100,000 population, they calculated the number of SAH cases and the total adult population for the year.
“Smoking and hypertension are two of the strongest risk factors for subarachnoid hemorrhage,” Dr. Otite said. “Hypertension is more prevalent in Black people in the United States, and Black patients with hypertension are more likely to have it uncontrolled.”
Racism, toxic stress
Anjail Sharieff, MD, associate professor of neurology at UT Health, Houston, said aside from a high rate of common SAH risk factors such as hypertension, Black Americans also face a barrage of inequities to health education and quality health care that contributes to higher SAH rates.
“The impact of toxic stress related to racism and discrimination experiences, and chronic stress related to poverty, can contribute to hypertension in Black people,” Dr. Sharieff said, adding that these factors contribute to stroke risk and are not usually accounted for in studies.
Dr. Sharieff said many of her first-time patients end up in her office due to a heart attack or stroke because they were previously uninsured and did not have access to primary care. “We need to begin leveraging trust with people in communities – meeting people where they are,” to educate them about hypertension and other health issues, she said.
A shining example of community engagement to reduce hypertension in Black communities was the Cedars-Sinai Barbershop Study, where 52 barbershops in Los Angeles implemented blood pressure checks and interventions among customers. A year later, the project was still working.
“Once we can identify the health problems in Black communities,” said Dr. Sharieff, “we can treat them.”
Dr. Otite and Dr. Sharieff report no relevant financial relationships.

Less than 6 hours of sleep a night linked to serious, chronic illness
, results of a large study show.
Researchers at University College London and Université Paris Cité found that beginning at age 50, those who slept 5 hours or fewer a night had a 30% higher risk of developing multiple chronic diseases over time than those who slept at least 7 hours a night. By the time the participants were aged 70 years, that risk had increased to 40%.
Diseases for which there was a higher risk included diabetes, cancer, coronary heart disease, stroke, heart failure, chronic obstructive pulmonary disease, chronic kidney disease, liver disease, depression, dementia, Parkinson’s disease, and arthritis.
“It is important to take care of our sleep,” lead investigator Séverine Sabia, PhD, said in an interview. Dr. Sabia is a researcher and epidemiologist at Université Paris Cité and INSERM in Paris, and the University College London.
She noted that the source of the sleep problem must be addressed, but in cases in which there is no medical reason for sleep paucity, “healthy sleep habits are a must. These include keeping a regular sleep schedule, a healthy lifestyle – physical activity and light exposure during the day, and a light dinner – and avoidance of screens for a half hour before sleep.”
The study was published online in PLOS Medicine.
Risk of multiple chronic diseases
Prior research suggests that sleeping for 5 hours or less or 9 hours or more is associated with cancer and cardiovascular disease (CVD).
For the current study, Dr. Sabia and her team asked nearly 8,000 civil servants in the United Kingdom as part of the Whitehall II cohort study to report the amount of sleep they received beginning at age 50 every 4 to 5 years for the next 25 years. Study participants were free of chronic disease at age 50 and were mostly male (67.5%) and White (90%).
The investigators found that at age 50, those who slept 5 hours or less were 30% more likely to be diagnosed with multiple chronic diseases over time, (hazard ratio, 1.30; 95% confidence interval, 1.12-1.50; P < .001) compared with their peers who slept 7 hours.
At age 60, those who slept 5 hours or less had a 32% greater risk of developing more than one chronic disease (HR, 1.32; 95% CI, 1.13-1.55; P < .001), and by age 70, this risk increased to 40% compared with their peers who slept 7 hours a night (HR, 1.40; 95% CI, 1.16-1.68; P < .001).
For participants who slept 9 or more hours per night, only those aged 60 (HR, 1.54; 95% CI, 1.15-2.06; P = .003) and 70 (HR, 1.51; 95% CI, 1.10-2.08; P = .010) were at increased risk of developing more than one chronic disease.
Dr. Sabia noted that previous studies have shown that those who slept less than 5 hours a night were more likely to develop diabetes, hypertension, CVD, or dementia. “However, chronic diseases often coexist, particularly at older ages, and it remains unclear how sleep duration may be associated with risk of multimorbidity,” she said. She noted that several biological hypotheses have been proposed as underlying the association.
“Sleep is important for the regulation of several body functions, such as metabolic, endocrine, and inflammatory regulation over the day, that in turn, when dysregulated, may contribute to increased risk of several chronic conditions.”
The authors acknowledge several study limitations, including the fact that the data were obtained via participant self-reports, which may be affected by reporting bias. There was also a lack of diversity within the study sample, as the civil servants were mostly male and White. In addition to this, the investigators note that the study population of British civil servants tended to be healthier than the general population.
Chicken or egg?
Commenting on the findings for this article, Charlene Gamaldo, MD, urged caution in interpreting the findings. She noted that self-reporting of sleep has been established as “potentially problematic” because it doesn’t always correlate with actual sleep.
Dr. Gamaldo, who is professor of neurology and psychiatry at Johns Hopkins University in Baltimore and the medical director of the JHU Center for Sleep and Wellness, said previous studies have shown that underestimation of sleep can occur among those suffering with insomnia and that overestimation can be seen among individuals with behaviorally based chronic, insufficient sleep.
Dr. Gamaldo also raised the issue of sleep quality.
“Getting 5 hours of high-quality sleep is less worrisome than one getting 8 hours of terrible-quality, based on untreated sleep apnea, for instance,” she noted.
In addition, she pointed out that chronic health problems can interrupt sleep. “Which is the chicken, and which is the egg?” she asked.
“For me, the take-home of current literature and supported by this paper is that individuals with sleep quality complaints, short duration, or related impact in daytime function should address them with their treating provider to assess for the underlying cause.
“Those sleeping under 5 hours without complaints should consider whether 5 hours really represents the amount of sleep they need to wake rested and function at their best. If answer is no, they should prioritize getting more sleep,” she concluded.
The study was funded by the National Institute on Aging, the National Institute of Health, the UK Research Medical Council, the British Heart Foundation, the Wellcome Trust, and the French National Research Agency. The investigators and Dr. Gamaldo report no relevant financial relationships.
