Sedentary behavior can kill even if you exercise


A new study concluded that sedentary behavior increases the risk of early death, although exercise after several hours sitting.

Being seated for excessively long periods of time is a risk factor for early death, even if you exercise. This is the conclusion of an American study, published this week in the Annals of Internal Medicine, which aimed to analyze the association between sedentary behavior in prolonged and uninterrupted episodes as well as mortality.

The research was conducted by Keith Diaz of the Department of Medicine at Columbia University in New York and was based on a sample of approximately 8,000 adults. The study verified the existence of a direct relationship between seated time and the risk of early mortality. As the time spent sitting increases, so does the risk of early death, with people sitting for less than 30 minutes at a lower risk. To measure the time of sedentarism, the team of researchers used accelerometers.

Analyzing the data, the team found that sedentary behavior averaged about 12.3 hours on the average of 16 hours a person is awake.

The results also indicated that, in general, the risk of death of the participants increased in conjunction with the total time they spent sitting, regardless of age, gender, race, body mass index or exercise habits.

“We found that there was no specific threshold or point where the risk of death increased dramatically”, the researcher explained”. To give a specific number, those who sat for more than 13 hours a day had a twice as much risk compared to those who sat less than 11 hours a day”, he added.

The results also indicated that those who sit less than 30 minutes had a 55% lower risk of death than those who sit for periods longer than half an hour.

The study also found that people who sit frequently for periods longer than 90 minutes had a two-fold higher risk of death compared to those who sit for shorter periods.

The American Heart Association is an American organization dedicated to fighting heart disease and stroke, it encourages citizens to “sit down and move more”, but for the investigator, this guideline “would be like telling someone to exercise more without explaining how”, Diaz said.
