A recent study reveals that the stress of caregiving may significantly increase the risk of developing high blood pressure (hypertension) in Black women aged 21 to 44, a group already known to experience higher rates of the condition compared to women from other racial and ethnic backgrounds.
While previous research has shown a connection between caregiving stress and hypertension in middle-aged and older Black women, this younger demographic had been largely understudied. The new findings, published in the American Heart Association’s journal Hypertension, highlight that caregiving stress may be a critical factor in the development of hypertension in reproductive-age Black women, with serious implications for cardiovascular health.
Study Highlights: Stress and Hypertension in Black Women
The study, which followed participants for an average of 7.4 years, found that 43.5% of all participants developed hypertension. Among those reporting moderate to high caregiving stress, 51.7% developed high blood pressure, compared to 40.6% of those with low or no caregiving stress. The results suggest that chronic stress from caregiving may be a significant contributor to the development of hypertension, a major risk factor for cardiovascular disease (CVD).
“We believe that caregiving stress, as a source of chronic stress, may significantly contribute to the development of hypertension in reproductive-age Black women,” said Milla Arabadjian, PhD, corresponding author of the study and assistant professor at NYU Grossman Long Island School of Medicine. Arabadjian emphasized that identifying modifiable risk factors like caregiving stress is essential for tailoring prevention strategies for this population.
The study’s findings are particularly relevant given the high rates of uncontrolled hypertension among younger Black women. Addressing factors like caregiving stress may play a crucial role in improving management and prevention of hypertension within this group.
The Impact of Caregiving on Women’s Health
The importance of the study is underscored by recent comments from U.S. Surgeon General Dr. Vivek Murthy, who highlighted the rising levels of stress and mental health issues experienced by caregivers over the past decade. Since women make up the majority of informal caregivers, they are especially vulnerable to the negative health impacts of caregiving stress.
Study Methodology and Key Findings
The analysis examined data from the Jackson Heart Study (JHS), one of the largest ongoing studies focused on cardiovascular health in Black adults. The study, which began in 2000, follows the health of more than 5,300 Black adults across three Mississippi counties.
To assess caregiving stress, participants were asked to report their experiences using a key question from the global perceived stress scale: “Over the past 12 months, how much stress did you experience related to caring for others?” Responses were measured on a four-point scale, from “not stressful” to “very stressful.” Based on their responses, participants were categorized into two groups: low/no caregiving stress and moderate/high caregiving stress.
Hypertension was defined as having a systolic blood pressure above 140 mm Hg, a diastolic blood pressure above 90 mm Hg, or self-reporting the use of antihypertensive medication at follow-up exams.
Tailored Solutions to Address Caregiver Stress
Senior study author Tanya M. Spruill, PhD, associate professor at NYU Langone Health, stressed the importance of identifying the root causes of caregiver stress in order to develop effective interventions. “Given the high lifetime risk of cardiovascular disease, especially among reproductive-age Black women, we need to better understand the sources of strain and address them,” said Dr. Spruill. “If lack of affordable childcare is a contributing factor, linking women to childcare resources could help. If communication challenges with a child or elderly relative are the issue, targeted education may be beneficial.”
Implications for Future Research and Policy
This research sheds light on the pressing need for addressing caregiver stress, particularly in communities that are at higher risk for hypertension and cardiovascular disease. The study emphasizes the importance of creating policies and support systems that help caregivers manage their stress levels, which could ultimately reduce the incidence of hypertension in this vulnerable population.
The research team included experts from NYU Langone Health, Columbia University, the University of Alabama at Birmingham, Wake Forest School of Medicine, the University of Michigan, and the University of Mississippi Medical Center.
As caregiving continues to be a primary source of stress for many women, the findings of this study call for a deeper understanding of how caregiving impacts health and for the development of strategies to support caregivers, particularly in high-risk groups like Black women.
