Sitting for 8 hours a day increases the risk of death and heart disease by 18/06/2022

If you work sitting in front of a computer, be careful! One study showed that sitting for six to eight hours a day increases the risk of premature death and heart disease by 12-13%. Anyone who stays longer than eight hours a day increases that risk by 20%.

The study was conducted by more than 100,000 people from 21 countries and published in the journal Jama Cardiology on Wednesday (15). According to the authors, the link between physical inactivity and health problems was most evident in low- and middle-income countries. According to them, meeting the WHO (World Health Organization) recommendations for physical activity can reduce the risk of prolonged stay.

How the research was conducted

  • In January 2003, 105,677 participants from 21 countries were recruited. They were between the ages of 35 and 70 at the time and were tracked until August 2021. Participants came from 21 different countries, from low, middle and high income.
  • Daily sitting time was measured using the International Physical Activity Questionnaire.
  • During an average follow-up of 11.1 years, 6233 deaths and 5696 major cardiovascular events (myocardial infarction 2349, 2966 strokes, 671 heart failure and 1792 cardiovascular deaths) were recorded.
  • Compared with the reference group (less than 4 hours per day per day), longer stay (8 hours per day or more) was associated with a higher risk of death from all causes and cardiovascular events.
  • When analyzed by the country’s income levels, the temporary living and poor health union was stronger in low- and middle-income countries.
  • Those who stayed longer and who had less activity had a higher risk (up to 50%), while those who stayed longer but also had a higher risk had a lower risk of around 17%.

the problem is global

In a statement, Scott Lear, a professor of health sciences at Simon Fraser University in Canada, who led the study, said “the main message here is to reduce the amount you spend.” “If you have to sit all that time, doing more exercise at other times of the day will eliminate that risk,” he said.

Doctors should consider recommending staying longer and exercising more physically, he said, as it is a low-cost intervention that can be very beneficial.

“Our study found that a combination of sitting time and physical inactivity was the cause of 8.8% of all deaths, which is close to the contribution of smoking (10.6%). It is a global problem that has a very simple solution. Planning time. Departure. in that chair is a good start, ”he said.
