The longer time sitting working seat is, the greater the risk of premature death for a person, according to a new American scientific study, which confirms similar findings from previous investigations.
Scientists recommend frequent breaks from the sitting position and stand upright. The smallest risk of premature death, according to the survey, has those who "break" the immobility at intervals of no more than half an hour (30 minutes) - something that should especially be taken into account by those who do sedentary office work.
Researchers at the Medical Centers at Columbia and Cornell University in New York, led by Dr. Kith Diaz, who published the issue in the American medical journal Annals of Internal Medicine, analyzed data for almost 8,000 people over the age of 45.
Stopping time was measured for one week with a specific device that wore each participant and then correlated with the mortality from any cause at a four-year depth, during which 340 people died. The mean time of physical restraint during the day was 12.3 hours, from about 16 hours that was awake in 24 hours. The average uninterrupted physical resting time was 11.4 minutes.
It was found that the more time you spent sitting (at home, at work, in transport, etc.), the more likely it was to prematurely die from a cause. Also, the risk was greater as longer periods of consecutive sitting, without interruptions in the middle.
The risk is greater for those who combine both of them, that is, they spend a lot of hours sitting together in the day and, at the same time, spend long periods of sitting, without having to stand upright.
Someone who was still 13.2 hours during the day, had a 2.6-fold increased risk of premature death, compared to someone who was staying less than 11.5 hours within 24 hours. If the mean interval of one person's rest during the day lasted more than 12.5 minutes, the risk of premature death was almost double that of someone who was not sitting more than 7.7 continuous minutes on average.
Indeed, the increased risk of sedentary life was independent of a person's age, gender, weight or physical activity. In other words, regardless of whether one is practicing and how much, it must at the same time limit both the total and the consecutive time of sitting.
