Air Pollution Can Trigger Diabetes
A recent study showed a strong relationship between diabetes risk and exposure to exhaust fumes, industrial smoke, and other types of fine particulate air pollution.
People living in areas with air quality levels below the safety limit of the Environmental Protection Agency has the prevalence of diabetes more than 20 percent higher than those exposed to less air pollution.
"We know that exposure to air pollution is a risk factor for cardiovascular disease," said John Brownstein, PhD, from Children's Hospital Boston and Harvard Medical School. "This is just one part of the evidence that the health effects of pollution was serious."
Brownstein and his colleagues calculate the combined data Lingkungkan American Board of fine airborne particulate air pollution results. Then link it with data from the CDC (Centers for Disease Control and Prevention) and the U.S. census on the number of people suffering from diabetes for years 2004 and 2005.
The analysis showed a strong and consistent relationship between levels of diabetes and level of air pollution.
Although this finding does not prove a direct link air pollution with epidemics of diabetes, but simply describes the role of other environmental factors in increasing the risk of diabetes in addition to other phenomena that are now emerging in the Western world, namely obesity.
In fact, in previous animal studies, chronic inflammation has been shown to improve insulin resistance, which leads to diabetes. Chemicals in air pollution has been associated with this inflammation.
"Therefore, our conclusion about this relationship may be stronger occur in obese people. Because, many chemicals accumulate in fat, "adds Brownstein.
