A third of the world’s adult population is physically inactive, the couch-potato lifestyle kills about 5 million people every year, experts contributing to a special feature in the medical journal The Lancet say.
“Roughly three of every 10 individuals aged 15 years or older – about 1.5 billion people – do not reach present physical activity recommendations,” Dr Pedro Hallal and colleagues said in a report that described the problem as a pandemic.
The Lancet Physical Activity Series Working Group paints an even grimmer picture for adolescents, with four out of five 13 to 15-year-olds not moving enough, the report said.
Inactivity was described for the study as failing to do 30 minutes of moderate physical activity five times a week, 20 minutes of vigorous activity three times a week, or a combination of the two ::::
The researchers found that inactivity increases with age, is higher in women than in men, and more prevalent in high-income countries.
A second study, comparing physical activity levels with population statistics on diseases like diabetes, heart problems and cancer, said lack of exercise claimed more than 5.3 million of the 57 million deaths worldwide in 2008.
It said inactivity was a risk factor comparable to smoking or obesity.
Lack of exercise causes an estimated 6 per cent of coronary heart disease cases, 7 per cent of type 2 diabetes (the most common form) cases, and 10 per cent of breast and colon cancers, it said.
Reducing inactivity by 10 per cent could eliminate more than half a million deaths every year, the report said, adding the estimates were conservative.
The human body needs exercise to help the bones, muscles, heart and other organs function optimally, but populations are walking, running and cycling less and less as they spend more time in cars and in front of computers, the investigators said.
The Lancet series called for global efforts to promote physical exercise by improving pedestrian and cyclist safety on city roads, for example, more physical education at school or promoting access to free public exercise spaces.
In a ecent study into the healthy habits of couch potatoes, a University of Queensland study has compared watching television to smoking and similar unhealthy habits. This comes on the back of a study last year with similar findings, do we sense a theme?
Professor David Dunstan of the Baker IDI Heart and Diabetes Institute, and colleagues, last year found an hour of TV viewing a day led to an 8 per cent higher risk of premature death, especially from cardiovascular disease. His team estimates that every single hour of TV watched after age 25 is associated with a reduction in life expectancy of around 22 minutes.
Each hour of TV you watch could cut 22 minutes from your lifespan,Veerman’s study has found.
Dr Lennert Veerman, from the School of Population Health at the University of Queensland in Brisbane, and colleagues, reported their findings in the British Journal of Sports Medicine :: Read the full article »»»»
