The Hindu Business Line : Prolonged desk jobs potentially life-threatening: study

LONDON: Hot on the heels of the threat from killer keyboards in the office, a research has suggested that prolonged desk work could be potentially life-threatening with associated risk of developing blood clots.

The research, published in the Journal of the Royal Society of Medicine, confirms previous studies that prolonged sitting at work represents an important risk factor for developing blood clots that may present even more of a risk than long haul flights.

"The current study represents a major advance from previous work in that it is a case-control study with considerably greater scientific merit than the previous case series," says Professor Mr Richard Beasley, the study leader from Wellington Hospital (C CDHB) in New Zealand.

The new study identified that prolonged sitting at work was associated with a two-fold increased risk of developing a deep vein thrombosis (DVT) or pulmonary embolism (PE).

Moreover, both the maximum number of hours seated at work as well as the number of hours seated without getting up was associated with an increased risk of both DVT and PE.

The authors of the study recommend that with the current state of knowledge it would seem prudent to advise all people who commonly sit for prolonged periods at a computer to undertake frequent leg and foot exercises and to take regular breaks away from their computer.

These findings were similar to the situation with travelers' thrombosis in which both the duration of the flight and immobility during the flight having been shown to be associated with an increased risk of DVT and PE.

The risk of developing blood clots with prolonged seated immobility is largely unrecognised. However, this study has shown that it is at least as important a factor as long distance air travel, Mr Beasley said. - PTI
