Exposure to air pollution was shown to increase the risk of obesity and diabetes in rats, according to a new study.
Researchers from Duke University exposed lab rats either to Beijing air or filtered air for 19 days; at the end, the group that got the highly polluted Beijing air had higher bad cholesterol levels (50%), triglycerides (46%) and total cholesterol (97%), factors that can affect the risk of developing obesity and diabetes, United Press International reports. Male rats exposed to pollution ended the study 18% heavier than their filtered air counterparts, and female rats ended the study 10% heavier.
If the same metabolic dysfunction were confirmed to occur in humans, one of the study’s authors said in a press release, “these findings will support the urgent need to reduce air pollution, given the growing burden of obesity in today’s highly polluted world.”
