- Two studies published in international journals have reported a link between air pollution levels and the incidence of type 2 diabetes in Chennai and Delhi.
- Indian cities have consistently dominated the tops of lists of places with the worst air for residents.
- Air quality of cities frequently several times higher than the limits set by the World Health Organisation.
- For every 10 μg/m3 increase a month in PM2.5 levels, fasting plasma glucose (FPG) increased by 0.21-0.58 mg/dL (milligrams per decilitre) and glycosylated haemoglobin (HbA1c) by 0.012-0.024 in Delhi.
- FPG increased −0.36-1.39 mg/dL and HbA1c 0.01-0.06 in Chennai.
- Over six months, a 10 μg/m3 change in PM2.5 levels resulted in a rough doubling of both ranges in Delhi.
- But it couldn’t be associated with a statistically significant result in Chennai.
- In annual average “PM2.5” could be related to a 9-36% higher risk of developing type 2 diabetes.
