Desk jobs double the risk of early death even with regular exercise, new research shows
37 per cent of Brits spend less than 30mins a day on their feet
DESK jobs nearly double the risk of dying early, a study says.
Workers who sit for long periods are in greater danger even if they exercise regularly.
But walking about every 30 minutes dramatically reduces the threat, say scientists.
Volunteers who sat for no more than half an hour at a time had the lowest risk of death.
The findings support a Cambridge University study last year which found one in six deaths — 90,000 a year — was caused by 9-to-5 office lifestyles.
Heart disease, strokes, cancer, type 2 diabetes and dementia were mainly to blame.
It also estimated 37 per cent of British adults spend less than 30 minutes a day on their feet.
In the latest research, a US team at Columbia University, New York, studied almost 8,000 adults over 45.

The biggest risk of early death was in those who sat for up to 90 minutes.
Researcher Monika Safford said: “Sitting really is the new smoking.
"We need creative ways to ensure we not only cut back on the amount we sit but increase regular bursts of activity.”
