Prolonged television watchers have a higher risk of fatal pulmonary embolism, a condition associated with long haul flights, reveals research presented at ESC Congress today by Mr Toru Shirakawa, public health research fellow in the Department of Social Medicine at Osaka University in Japan.1 The 18 year study in more than 86 000 people found that watching an average of five or more hours of television per day was associated with twice the risk of fatal pulmonary embolism as watching less than two and a half hours daily.

"The association between prolonged sitting and pulmonary embolism was first reported among air raid shelter users in London during World War II," said Mr Shirakawa. "Nowadays, a long haul flight in an economy class seat is a well known cause of pulmonary embolism that is called 'economy class syndrome'."

He continued: "Pulmonary embolism is a serious, sometimes fatal, lung-related vascular disease characterised by sudden onset of symptoms such as chest pain or difficulty breathing. The disease is caused by obstruction of the pulmonary arteries by blood clots, generally formed in the leg vessels. Risk factors include cancer, prolonged bed rest or sitting, and oral contraceptive use."
