Research published online in the British Journal of Sports Medicine suggests, watching television for approximately six hours daily could shorten the viewers life expectancy by almost five years. Competing with other well known behavioral risk factors, such as smoking and not enough exercise, the investigation indicates.
Sedentary behavior (as distinct from too little exercise) is linked with a increased risk of death, especially from heart attack or stroke. Watching TV makes up for a huge amount of sedentary activity, but its impact on life expectancy has not been evaluated, say the researchers.
To assemble a lifetime risk framework, researchers used previously published information on the connection between TV viewing time and death from analyses of the Australian Diabetes, Obesity and Lifestyle Study (AusDiab), together with Australian national population and mortality figures for 2008.
Including over 11,000 adults aged 25 or older, and beginning in 1999-2000, AusDiab is a national survey of a representative sample of the population.
