In a review of health, air pollution was first identified as a major contributor to death and disability caused for stroke, especially in developing nations.
Air pollution is among Top 10 Risks of stroke
Air pollution, both inside the kitchen fire and out of traffic fumes, classified among the ten leading causes of strokes, in addition to the known risks, such as smoking, hypertension and obesity .
“About 15 million people worldwide suffer strokes each year, of which nearly six million die and five million are disabled – including loss of vision or speech, paralysis and confusion. “
An international team of researchers analyzed data from a strip of other studies, official reports and statistics to create a model of risk of stroke mathematical estimation for 188 countries from 1990 to 2013.
“A surprising finding of our study is the unexpectedly high proportion of stroke attributable to air pollution, especially in developing countries burden,” said study co-author Valery Feigin, University of Auckland in New Zealand Technology .
The authors said that theirs was the first study to quantify the burden of race in the world in terms of years of healthy life lost due to people becoming ill, disabled, or dying from a stroke.
Globally, albeit with large differences between countries and regions, the main risk factors are high blood pressure, a diet low in fruits, overweight, eating too much salt, smoking, not eating enough vegetables, the team said .
environmental pollution entered the seventh and air pollution from household solid fuels in the eighth.
A diet low in whole grains and blood sugar completed the top ten.
The researchers found that 90.5 percent of the burden of stroke was attributable to “modifiable factors” – mainly behaviors such as smoking, eating too much sugar and not enough exercise, and the associated health problems, like diabetes and heart disease, these options result.
Control of lifestyle factors that played a much more important role in the rich countries to the poor, “could prevent about three-quarters of strokes worldwide,” Feigin said.
– Sugar up, down smoking –
The study air pollution as a “modifiable factor” also appears, which means that people or governments can do something to change it.
“These results are important for campaigns education, evidence-based planning, priority setting and resource allocation in the prevention of stroke,” they wrote in the Lancet Neurology.
“Air pollution has become a major contributor to the global burden of stroke, especially in low- and middle-income, and thus reduce exposure to air pollution should be one of the main priorities for reduce the burden of stroke in these countries. ”
In low- and middle-income Asia and Africa, almost a fifth of the burden of stroke was attributed to air pollution from home, while a similar percentage was attributed to ambient air pollution in China and India .
Air pollution may increase the risk of stroke in increased blood pressure, hardening of the blood vessels or causing them to become blocked.
The risk factor whose contribution was further reduced between 1990 and 2013 was the snuff smoke secondhand, according to the team, especially in developed countries.
The rapid growth of risk of stroke was drinking sugar-sweetened soft drinks
