There's a strong link between air pollution and adult diabetes, according to a new study.
US researchers analysed national data and found a 1% increase in diabetes rates for every 10 microgram per cubic meter increase in fine particulate air pollution, such as that found in car exhaust and smoke, USA Today reported.
"We didn't have data on individual exposure, so we can't prove causality, and we can't know exactly the mechanism of these peoples' diabetes," said study co-author John Brownstein of Children's Hospital Boston. "But pollution came across as a significant predictor in all our models."
The link between air pollution and diabetes was evident even in areas with air pollution levels considered safe according to US Environmental Protection Agency standards, USA Today reported.
The study appears in the October issue of the journal Diabetes Care.
