Sedentary behaviour and dementia risk in older adults

A recent study links prolonged sitting with increased dementia risk — a reminder that daily movement matters far beyond bone health.

Most people at risk of osteoporosis are also at an age where cognitive health becomes a growing concern. A published cohort study has now shown that prolonged sedentary time — regardless of overall exercise level — is independently linked to a higher risk of incident dementia.

Why it matters

The takeaway isn't just to exercise more, but to sit less. Short, frequent bouts of gentle movement throughout the day may be as important as a single longer session — and that pattern happens to align well with what supports bone and vascular health too.
