A new research study has concluded that the longer Americans sit, the sooner they die.
The study published by Peter T Katzmarzyk1 and I-Min Lee in BMJ Open examined the impact of sitting and watching TV on life expectancy in the U.S.
And the findings are scary.
The authors conclude that life expectancy in the USA would be two years higher if adults reduced their time spent sitting to less than three hours a day.
There’s a direct impact between TV viewing and life expectancy too – Americans’ life expectancy would increase by 1.38 years higher if they cut TV television viewing to less than two hours a day.
Sitting or TV watching are sedentary activities that have been linked to type 2 diabetes, cardiovascular disease mortality and all-cause mortality.
The authors caution that, “Life expectancy is a population statistic and it does not apply to individuals” but conclude that “extended sitting time and television viewing may have the potential to reduce life expectancy in the USA.”
Life expectancy in the U.S. is 78.2 years, lower than Cuba, Chile and Puerto Rico.
On the life expectancy list prepared by the United Nations, the U.S. ranks 38th.
