Square eyes the least of your prob­lems

EVERY hour you spend sit­ting watch­ing TV makes you more likely to die from in­flam­ma­tory-re­lated dis­eases, Mel­bourne re­searchers have found.

Baker Heart and Di­a­betes In­sti­tute re­searchers have found that even mod­er­ate view­ing of be­tween two and four hours a day is risky, with every ex­tra hour of seated TV view­ing each day associated with a 12 per cent higher risk of in­flam­ma­tion-re­lated death.

Re­searchers an­a­lysed the life­styles, hours of daily tele­vi­sion view­ing, in­flam­ma­tory mark­ers, and causes of death of al­most 9000 adults, who were fol­lowed up 13 years af­ter first tak­ing part in the Aus­tralian di­a­betes, obe­sity and life­style study.

Af­ter ex­clud­ing cancer and car­dio­vas­cu­lar-re­lated deaths, they found that every ex­tra hour of TV time in­creased the risk of in­flam­ma­tory-re­lated death. The risk was sim­i­lar, but smaller, among non­smok­ers in the co­hort.

“We know sit­ting in­volves re­duced mus­cle ac­tiv­ity, and there­fore re­duced blood flow,” lead au­thor and se­nior re­searcher at Baker’s phys­i­cal ac­tiv­ity re­search unit, Dr Me­gan Grace said. “We think this stag­na­tion in the blood ves­sels may be lead­ing to an ac­cu­mu­la­tion of in­flam­ma­tory mark­ers in the blood and mus­cles.”
