Topic: Risk, prevention and care in population studies

Over a median follow-up of 5.9-7.9 years, 3,492 dementia cases were identified. Falls were associated with a 70% higher risk of dementia (pooled HR = 1.70, 95% CI: 1.57-1.84). In the no-fall group, compared with inactivity, low, moderate, and high physical activity were progressively associated with lower risks of dementia (HRs = 0.63, 0.53, 0.43) and falls (HRs = 0.77, 0.68, 0.58). These protective effects were consistent among fallers, with similar dose-response gradients. Falls substantially increased dementia risk. Higher levels of physical activity were linked to lower risks of both dementia and falls, regardless of fall history.

Key findings

Over a median follow-up of 5.9-7.9 years, 3,492 dementia cases were identified.
Falls were associated with a 70% higher risk of dementia (pooled HR = 1.70, 95% CI: 1.57-1.84).
In the no-fall group, compared with inactivity, low, moderate, and high physical activity were progressively associated with lower risks of dementia (HRs = 0.63, 0.53, 0.43) and falls (HRs = 0.77, 0.68, 0.58).
These protective effects were consistent among fallers, with similar dose-response gradients.
Falls substantially increased dementia risk.

Why it matters

Across three cohorts, falls were linked to a 70% higher risk of dementia, and higher physical activity was linked to lower risks of both dementia and falls. These are observational associations, so they cannot prove that activity prevents dementia.
