Watching the Olympics probably made some people feel a little guilty about not
exercising. The truth is, if physical inactivity were a sport, a lot of us could give a
gold-medal performance. Or should we say non-performance?
To mark the London Olympics, the Lancet, a British medical journal, published a series
of papers about this problem. Public health experts say physical inactivity is the
world's fourth leading cause of death. They estimate that inactivity plays a major part
in six to ten percent of deaths from non-communicable (diseases). These include
conditions like heart disease, diabetes, and colon and breast cancer.
I. Min Lee at the Harvard School of Public Health worked with a team that studied
inactivity. She says the findings are conservative and may even (underestimate) the
problem.
I. MIN LEE: "Physical inactivity is (harmful) to health, as harmful as far as deaths are
concerned as smoking."
The researchers compared data on physical inactivity with disease rates in one hundred
twenty-two countries.
I. MIN LEE: "So when we did our analysis, we looked at increased risk of disease after
taking into account other health habits that might be associated with physical activity.
For example, we know that if you are active, you probably smoke less. Additionally we
factored out (obesity), independent of the fact that active people also tend to weigh
less."
Harold Kohl from the University of Texas School of Public Health also worked on the
special report. He says physical inactivity should be recognized as a (global) epidemic.
HAROLD KOHL: "We have to realize that high income countries are the most inactive around
the world, but low to middle income countries are not going to be far behind as things
change, as their economies improve and their people rely more on the improvements that
basically engineer physical activity out of our daily lives."
Harold Kohl points to campaigns that continue to reduce smoking and alcohol use. He says
the time has come to target physical inactivity as a major threat to public health.
HAROLD KOHL: "It is not just telling someone to go out and be physically active, but how
we rely on the transportation sector or how our cities or neighborhoods are designed,
how crime can be minimized to help people become more physically active in their
neighborhoods, simply walking to the store or walking down and being outside with
friends and family and so forth. These broader environmental issues are becoming much
clearer in terms of their effects."
I. Min Lee agrees -- and she challenges people to do one hundred fifty minutes a week of
(moderately) intense exercise.
I. MIN LEE: "Anything you can do is great! Even if you don't reach that 150 minutes a
week, a little is better than none and more is better than a little."
She plans to return every four years -- just like the Olympics -- to tell us how the
world is doing.
And that's the VOA Special English Health Report. How much physical activity do you get?
