Does having a lower rest-activity rhythm increase my risk of abdominal aortic aneurysm?
Having a lower rest-activity rhythm may increase your risk of abdominal aortic aneurysm. A large study using data from the UK Biobank found that people with lower levels of daily movement and disrupted sleep-wake cycles had a higher chance of developing this condition over time 2. This rhythm measures the strength and timing of your daily behavior, including how much you move versus rest 2.
What the research says
A study of 78,282 participants tracked for an average of 10.1 years found that lower rest-activity rhythm parameters were linked to higher abdominal aortic aneurysm risk 2. Specifically, the lowest tertile of relative amplitude showed a hazard ratio of 1.49 compared to the highest tertile 2. Other parameters like M10 and mesor also showed significant associations with increased risk 2.
The researchers suggest this link may exist because disrupted rhythms are tied to chronic inflammation and vascular smooth muscle cell dysfunction, which drive aneurysm development 2. Causal mediation analysis in the study examined how inflammatory markers might explain this connection 2.
While this study focused on rhythm, other research highlights different risk factors for abdominal aortic aneurysm complications. For example, a meta-analysis looked at repair techniques and found suprarenal fixation carried a higher risk of permanent dialysis compared to infrarenal fixation 1. Another study noted that poor preoperative nutritional status, measured by albumin and protein levels, was associated with higher rates of kidney injury and death after open repair 3.
What to ask your doctor
- How might my daily activity levels and sleep patterns affect my risk for an abdominal aortic aneurysm?
- What specific rest-activity rhythm parameters should I monitor if I am concerned about my vascular health?
- Are there lifestyle changes that can help improve my daily movement amplitude and reduce inflammation?
- How do my current activity levels compare to the risk factors seen in large population studies?
