Summary
This study explored how physical activity and abdominal fat relate to sleep problems in older adults with cardiometabolic multimorbidity (CMM – this is the presence of multiple cardiometabolic conditions such as diabetes, heart disease, and stroke) – a condition that increases the risk of cognitive decline. Researchers found that low activity levels and higher belly fat each raised the risk of poor sleep, a known contributor to brain aging. Those with both risk factors were over five times more likely to have sleep disorders. Since sleep is essential for memory and brain repair, managing these lifestyle factors is crucial for cognitive health.
Key Takeaways
✅ Poor sleep affected nearly half of older adults with CMM.
✅ Low physical activity raised sleep disorder risk by 3.6 times.
✅ Higher belly fat (measured by ABSI) increased sleep risk by 46%.
✅ The worst sleep outcomes were seen in those with both risk factors.
✅ Women and adults over 70 were especially vulnerable.
Why It Matters for You
Sleep is vital for brain health—clearing toxins, consolidating memory, and supporting mood. Regular movement and trimming abdominal fat aren’t just heart-healthy—they may also help protect your memory and cognitive function as you age.
