Americans may be living a little more from the possibility that they will spend less time on lowering, another study says.

The investigation found that reducing the daily normal sitting time to less than three hours would extend the future of the US by two years. Reducing the time spent in front of the TV every day to less than 2 hours per day would extend the future by 1.4 years.

The study complements an evolving body of evidence suggesting that sitting itself is wild. While previous research examined the risks to individual well-being, the new study analyses the risk of sitting for the entire population, said study specialist Peter Katzmarzyk of the Pennington Biomedical Research Center in Baton Rouge, La. The study “highlights inpatient behaviour as a major risk factor such as smoking and weight,” said Katzmarzyk.

Various studies have shown that our lifestyle could be responsible for around 173,000 cases of illness each year.

As the US is falling somewhere in the range of 4.5 to 5 hours a day, a major change in population behaviour is expected to influence the future, Katzmarzyk said. This could be achieved by changes in the working environment, for example by using standing work areas, and by less television.

Katzmarzyk and his partners analysed data from five, before considering more than 167,000 adults, who studied the relationship between sitting and the risk of passing on for any reason in the next four to 14 years. The researchers also collected data from US surveys conducted between 2005 and 2006 and between 2009 and 2010 to calculate the time Americans spent staring at the TV and sitting down every day.

About 27 percent of the exams passed could be attributed to sitting and 19 percent to watching television, the specialists said.

The study adds to the evidence that “despite concerns about active work practices, we should also be concerned about inpatient practices,” said Mark Tremblay, an exploration supervisor at the Eastern Ontario Research Institute's Children's Hospital, which he was not involved in the investigation.

With countless people sitting late, the impact on the general population is significant, Tremblay said.

The scientists found that their investigation accepted an interface between inpatient behaviour and the risk of kicking the bucket, which should authorise further research, they said. In addition, the investigation depended on members' own reports of sitting and watching television, which may not be entirely accurate.

The investigation will be published online today (9 July) in the BMJ Open diary.

Pass it on: Reducing seating to less than three hours per day could extend the future of the US by two years, analysts estimate.
