What This Means
This research suggests that older adults living in the community spend a large portion of their day — about 9.2 hours — sitting, while spending roughly 4.1 hours standing, 1.4 hours walking, and 7.1 hours sleeping. These findings come from a large Norwegian study of over 8,000 adults aged 65 and older, where participants wore accelerometers that tracked their movements around the clock. Advanced machine learning models were used to classify different types of activity, such as walking, running, cycling, standing, sitting, lying awake, and sleeping.
The study found that as people got older, they tended to sit more and lie awake more, while standing and walking less. Women were more active in terms of standing but walked less and sat less compared to men, and they also slept more. People with higher levels of education tended to stand and walk more and sit less, suggesting that education may be linked to healthier movement patterns in older age.
This research matters because it provides a detailed, real-world picture of how older adults actually distribute their time across different movements and postures throughout the day. This kind of data can help public health officials and researchers design better interventions to encourage older adults to be more active and less sedentary, and it offers a reference point — or benchmark — for comparing future studies on how movement patterns relate to health outcomes in aging populations.
