A study of 792 family and unpaid caregivers with cardiovascular conditions found that disrupted sleep, negative emotions and heavier care demands were associated with greater caregiving burden or psychological distress. The findings point to caregivers’ own health and well-being as important factors, but the study does not show that caregiving caused distress.
A study of 792 family and unpaid caregivers with cardiovascular conditions found that disrupted sleep, negative emotions and demanding care responsibilities were associated with greater caregiving burden or psychological distress. Published in the Journal of Applied Gerontology, the research focuses on people caring for older adults living in the community and highlights how caregivers’ own health may factor into the strain they report.
Led by Kyeung Mi Oh of George Mason University’s College of Public Health, the study analyzed data from the National Health and Aging Trends Study and the National Study of Caregiving. Participants cared for older adults and reported cardiovascular conditions including hypertension, heart disease or a previous heart attack. Researchers assessed perceived caregiving burden and psychological distress, including symptoms of anxiety and depression.
Caregivers reporting more disrupted sleep, low energy, reduced leg strength, longer caregiving hours and more negative emotions also reported greater burden. Trouble falling back asleep, breathing problems during sleep and negative emotions were associated with greater psychological distress. Burden itself was associated with distress, though the findings do not establish that one caused the other.
Hypertension was the most commonly reported condition, affecting 92.3% of participants. Most caregivers were at least 65 years old, 60.9% were women, and nearly half were spouses or partners. The researchers also found that younger caregivers and women reported greater burden. More positive emotions were associated with lower burden and distress.
Caregivers’ Health Shapes Reported Strain
The findings draw attention to a group balancing care responsibilities with their own cardiovascular health. Poor sleep and psychological distress are relevant to people managing heart conditions, but this study measured associations; it did not establish that caregiving strain worsens cardiovascular disease or causes anxiety and depression.
Oh said health care providers should ask about caregiving duties and how they affect sleep, emotional well-being and management of cardiovascular conditions. Such conversations could help identify caregivers who may need further assessment or support, according to the study’s lead author. The results also suggest that considering caregivers’ own physical and emotional circumstances may be useful when evaluating their reported burden.

How the Caregiver Study Was Conducted
The research examined family and unpaid caregivers supporting older adults living in the community, rather than focusing on care provided in institutional settings. It used information from two national studies and analyzed participants’ reports of their health, care demands, sleep, emotions and perceived burden or distress.
The authors reported that caregivers’ own health and well-being appeared more closely tied to burden and distress than the health conditions of the people receiving care. They also found an unexpected association: caregivers reporting more support had greater distress. The researchers cautioned that this does not show support causes distress; people facing more difficult situations may be more likely to seek or receive help.
“Our findings suggest that caregivers’ sleep, physical functioning, emotional well-being, and caregiving demands are important factors associated with caregiving burden and psychological distress.”

Associations Do Not Establish Cause
The study identifies associations, not cause and effect. It does not show whether caregiving demands led to sleep problems or distress, whether health challenges made caregiving feel more burdensome, or whether both were shaped by other factors. The supplied report does not provide details on how long participants were followed or whether the results apply to caregivers outside the study population.
The support finding also remains open to interpretation: greater reported support coincided with greater distress, but the researchers said this does not mean support itself is harmful. The report provides no estimate of how much any one factor changed a caregiver’s risk, and its findings should not be treated as a diagnosis or individual prediction.
Further Research and Clinical Questions
The study’s authors call for attention to caregivers’ sleep, emotional well-being, physical functioning and care demands. The report does not announce a specific follow-up study or a planned intervention. Further research would be needed to clarify how these factors change over time and whether particular forms of support reduce burden or distress.
For now, the study suggests that clinicians may ask patients with cardiovascular conditions whether they provide care and how that role affects their health routines and well-being. Decisions about symptoms or treatment should be discussed with a qualified health professional.
Key Questions
What did the study find?
Among 792 caregivers with cardiovascular conditions, disrupted sleep, negative emotions and heavier care demands were associated with greater burden or psychological distress. The study did not establish that these factors caused distress.
Who took part in the research?
Family and unpaid caregivers with conditions including hypertension, heart disease or a previous heart attack, who were caring for older adults living in the community. Hypertension was reported by 92.3% of participants.
Does the study show caregiving causes anxiety or depression?
No. Researchers found associations with psychological distress, which they assessed using symptoms of anxiety and depression. The findings do not establish that caregiving caused those symptoms.
Why was greater support linked with greater distress?
The researchers cautioned that the association does not mean support causes distress. Caregivers in more difficult situations may be more likely to seek or receive help, but the report does not resolve the explanation.
