The , published in the Lancet to coincide with the build-up to the Olympics, estimates that about a third of adults are not doing enough physical activity, causing 5.3m deaths a year. That equates to about one in 10 deaths from diseases such as heart disease, diabetes and breast and colon cancer.
Researchers said the problem was now so bad it should be treated as a pandemic. And they said tackling it required a new way of thinking, suggesting the public needed to be warned about the dangers of inactivity rather than just reminded of the benefits of being active. The team of 33 researchers drawn from centres across the world also said governments needed to look at ways to make physical activity more convenient, affordable and safer. It is recommended that adults do 150 minutes of moderate exercise, such as brisk walking, cycling or gardening, each week.
The Lancet study found people in higher income countries were the least active with those in the UK among the worst, as nearly two-thirds of adults were judged not to be doing enough. The researchers admitted comparisons between countries were difficult because the way activity was estimated may have differed from place to place. Nonetheless, they said they remained confident that their overall conclusion was valid.
But others questioned equating smoking with inactivity. While smoking and inactivity kill a similar number of people, smoking rates are much lower than the number of inactive people, making smoking more risky to the individual.
How sedentary or how active is your lifestyle today? Do you take time to check on your health or to make sure that you do not live an inactive lifestyle?
