People who work in jobs that require less physical activity - typically office and desk-based jobs - are at a lower risk of subsequent poor cognition than those whose work is more physically active, suggests new research from the University of Cambridge.

Lack of physical activity and exercise are known risk factors for major health conditions, including cognitive impairments such as memory and concentration problems. However, evidence as to whether physical activity actually protects against cognitive decline has often been mixed and inconclusive.

"Our analysis shows that the relationship between physical activity and cognitive is not straightforward," explained Hayat. "While regular physical activity has considerable benefits for protection against many chronic diseases, other factors may influence its effect on future poor cognition.

"People who have less active jobs - typically office-based, desk jobs - performed better at cognitive tests regardless of their education. This suggests that because desk jobs tend to be more mentally challenging than manual occupations, they may offer protection against cognitive decline."
