Air pollution may trigger diabetes

Boston, lifestyle and excessive calories in the body have been the main cause of type 2 diabetes. But it turns out there are additional factors that helped trigger the development of diabetes, namely air pollution.
Why do diabetic trigger air pollution?
Here’s an explanation from the scientists at Children’s Hospital, Boston, to be published in the October issue of Diabetes Care. If the particles of air pollution is too much enters the body, the body will become inflamed.
Well, here’s the inflammation that would interfere with the action of insulin. Because of impaired insulin action will occur resistance (resistance) of insulin in the body that makes people get diabetes.
These findings are consistent with previous laboratory studies that found that increased insulin resistance in rats exposed to particle pollution in the air and also an increase in inflammatory markers that may contribute to insulin resistance.
In the latest study, researchers focused on the fine particle size from 0.1 to 2.5 nanometers, or known as PM2.5, the main component contained in the fog and smoke exhaust from motor vehicles. The result, for every increase of 10 g/m3 in PM2.5 exposure, there is a 1 percent prevalence of diabetes.
“In addition to research in the laboratory, we also combine data from the Environmental Protection Agency (EPA) with data from the Centers for Disease Control (CDC) and the U.S. census to ensure the prevalence of diabetes of adults,” explains John Brownstein, PhD, of Children’s Hospital Informatics Program, such as reported by Medindia on Thursday (9/30/2010).
According to Brownstein, the diabetes risk factors are known, such as obesity, geographic latitude, ethnicity and population density (a measure of urbanization), then the air pollution could be one trigger the development of diabetes.
“Many environmental factors that can contribute to the epidemic of diabetes around the world. In addition to excess calories, pollution could be an additional factor,” notes Allison Goldfine, MD, head of clinical research at the Joslin Diabetes Center.
