One in Seven Diabetes is Due to Air Pollution, Study Finds

A study that confirms the link between air pollution and diabetes already advanced by previous research. A new case of diabetes in seven is today due to air pollution, researchers said in a study published Saturday.

“Pollution has contributed to 3.2 million new cases of diabetes worldwide in 2016, representing about 14% of new cases,” wrote the authors, from the Washington School of Medicine in St. Louis (US). United). “Pollution is thought to reduce insulin production and cause inflammation, preventing the body from converting glucose from blood into energy,” said the researchers, who publish the study in The Lancet Planetary Health.

Fractures of the lower limbs

The 14% estimate comes from the medical data of 1.7 million American veterans, followed by a median of eight and a half years. All were originally chosen because they did not have diabetes. The researchers built a statistical model to see how air pollution in their place of residence could explain why they became diabetic. And the comparison was made with another affection where this pollution is not in question, the fractures of the lower limbs.

Factors favoring diabetes such as overweight and obesity have been taken into account. “Our research demonstrates a significant link between air pollution and diabetes in the world,” said medical professor Ziyad Al-Aly in a statement.

France cited as an example
“This is important because many economic lobbies say that current levels (of pollutant releases into the atmosphere allowed) are too stringent and should be increased. Evidence shows that these current levels are still not healthy enough and need to be lowered, “he added.

In addition, the proportion of diabetes due to polluted air is estimated to be higher in countries where regulations are less strict and less well respected, such as India, Papua New Guinea, Afghanistan and Guyana. . As an example, the opposite is true of “richer countries such as France, Finland and Iceland
