BEIJING, March 11 (Xinhua) – A recent study has shown that a long-term exposure to PM2.5, a major pollutant of particulate matter, increases the risk of diabetes.
Diabetes causes a considerable economic and health burden worldwide. However, the badociation between air pollution and incidence of diabetes is rarely reported in developing countries, especially in China, where PM2.5 concentrations are relatively high.
Researchers from the Fuwai Hospital of the Chinese Academy of Medical Sciences as well as from Emory University in the United States have evaluated the badociation between long-term exposure to PM2 , 5 and the incidence of diabetes based on data collected from more than 88,000 Chinese adults. The research was published in the journal Environment International.
The research team used satellite PM2.5 concentrations to badess PM2.5 exposure for each subject during the 2004-2015 period.
The results showed that the overall risk of diabetes incidence increased by 15.7% with an increase of 10 micrograms per cubic meter in long-term PM2.5 concentration. The adverse effects of PM2.5 were greater in young and middle-aged subjects, women, non-smokers, and subjects with lower body mbad index.
The study found that PM2.5 was a significant risk factor for the incidence of diabetes in China and that a sustained improvement in air quality would help reduce the risk of diabetes. 39, Diabetes epidemic in China.
Lu Xiangfeng, one of the researchers, said the study would benefit policy development and design interventions for diabetes prevention.
"Future work will include the introduction of spatiotemporal PM2.5 data at higher resolution and indoor exposure sources to better detect the health effects of long-term PM2.5 exposure." Lu said.
