'Compression socks don't stop DVT'

THERE is no evidence to support claims that wearing compression stockings prevents the development of deep vein thrombosis for passengers on flights.

THERE is no evidence to support claims that wearing compression stockings prevents the development of deep vein thrombosis for passengers on flights.

In recent years, the condition nicknamed "economy class syndrome" has caused anxiety amongst holidaymakers, business people and frequent fliers.

But Professor David Gradwell - Britain's first professor of Aerospace Medicine - said measures such as taking aspirin and wearing the high socks are not backed up by scientific research.

"The evidence to support that that is necessary is really not there," he said.

"There have been things like, 'everybody should take an aspirin' ... but again, it's an area of study that is probably, as yet, incomplete.

"To cut a long story short, the jury's still out."

Prof Gradwell, from King's College London said people most at risk from developing DVT were by far those who have a predisposition to blood clots, rather than where people sit on the aircraft or how much alcohol they drink.

However, he said all passengers - particularly those on long haul flights - should aim to stay hydrated and exercise in their seat or in the aisle to lessen the risk of developing the condition.

"There is a lot of debate still going on. It depends how long you're flying for, it depends what exercise you take on the flight, it depends on your predisposition - and that's what this is really aiming at," he said.

The professor said almost everybody could travel on commercial aircraft - except those with active tuberculosis, people who were coughing up blood, those with severe anaemia or individuals who have had a recent acute psychotic event.

"Flying is safe," he said.

"Millions of people do it every year without any issues at all."
