Long-term exposure to PM2.5 raises diabetes' risk

Long-term exposure to PM2.5, a major particle matter pollutant increases the risk of diabetes, finds a study.

Researchers from the Fuwai Hospital under the Chinese Academy of Medical Sciences as well as Emory University in the United States evaluated the association between long-term exposure to PM2.5 and diabetes incidence based on data collected from more than 88,000 Chinese adults, the Xinhua reported.

The team used satellite-based PM2.5 concentrations to assess PM2.5 exposure for each subject during the period 2004-2015.

For an increase of 10 micrograms per cubic meter of long-term PM2.5 concentration, the risk of diabetes incidence increased by 15.7 per cent, according to the study published in the journal Environment International.

The study would benefit policy making and intervention design in diabetes prevention, the researchers said.

"Our future work will focus on introducing spatiotemporal data of PM2.5 at higher resolution and indoor source of exposures to further detect the health effects of long-term exposure to PM2.5," said Lu Xiangfeng, from the Fuwai Hospital.

According to the World Health Organization (WHO), air pollution can lead to lung cancer, respiratory infection, stroke, and even heart disease.

Air pollution and diabetes are responsible for millions of death globally.

Data from the WHO show that in 2014, 8.5 per cent of adults developed diabetes, and that in 2015, this health condition resulted in 1.6 million deaths.
