Read the following passage about a study into 'sitting'.
The ease of our modern workday could come at the expense of our longevity. A new study of older women in the American Journal of Preventive Medicine finds that sitting for long stretches of time increases the odds of an untimely death. The more hours women in the study spent sitting at work, driving, lying on the couch watching TV, or engaged in other leisurely pursuits, the greater their odds of dying early from all causes, including heart disease and cancer.
Even women who exercised regularly risked shortening their lifespan if most of their daily hours were sedentary ones. “Even if you are doing the recommended amount of moderate to vigorous exercise, you will still have a higher risk of mortality if you’re spending too many hours sitting,” says Dr. JoAnn Manson, one of the study’s authors.
How much sitting can you safely do in a day? In the study, women who were inactive for 11 or more hours a day fared the worst, facing a 12% increase in premature death, but even lesser amounts of inactive time can cause problems. “Once you’re sitting for more than 6 to 8 hours a day, that’s not likely to be good for you,” Dr. Manson says. You want to avoid prolonged sitting and increase the amount of moderate or vigorous exercise you do each day, she adds.
Are the following statements true, false or not given?
1. The study looked at the effects of sitting on elderly women only.
2. A link was found between hours spent sitting and serious health problems.
3. The warnings about sitting do not apply to people who exercise regularly.
