Air pollution plays significant role in diabetes: study

PARIS, June 30, 2018 (BSS/AFP) – Air pollution caused one in seven new
cases of diabetes in 2016, according to a US study, which found even low
levels raised the chances of developing the chronic disease.

Diabetes has primarily been associated with lifestyle factors like diet and
a sedentary lifestyle, but research by the Washington University School of
Medicine in St Louis said pollution also plays a major role.

The study estimated that pollution contributed to 3.2 million new diabetes
cases globally in 2016 — or around 14 percent of all new diabetes cases
globally that year.

“Our research shows a significant link between air pollution and diabetes
globally,” said Ziyad Al-Aly, the study’s senior author.

Pollution is thought to reduce the body’s insulin production, “preventing
the body from converting blood glucose into energy that the body needs to
maintain health,” according to the research.

Al-Aly said the research, published in the Lancet Planetary Health, found
an increased risk even with levels of air pollution currently considered safe
by the US Environmental Protection Agency (EPA) and the World Health
Organization (WHO).

“This is important because many industry lobbying groups argue that current
levels are too stringent and should be relaxed. Evidence shows that current
levels are still not sufficiently safe and need to be tightened,” he added.

– ‘A strong link’ –

Researchers working with scientists at the Veterans Affairs’ Clinical
Epidemiology Center, examined data from 1.7 million US veterans who did not
have histories of diabetes and were followed for a median of 8.5 years.

Patient information from the veterans was compared to air quality
information to examine the relationship between pollution and diabetes risk.

The scientists found the risk of developing diabetes “exhibited a strong
link to air pollution”.

They then devised a model to gauge diabetes risks over different pollution
levels and used data from the annual worldwide Global Burden of Disease
study, to estimate the prevalence of diabetes caused by bad air.

Diabetes affects more than 420 million people globally and is one of the
world’s fastest growing diseases.
