Highlights

• Air pollution, traffic noise and lack of green space have been associated with diabetes in analyses mainly focusing on one or two environmental factors at a time.
• We aimed to investigate if air pollution, road traffic noise and green space are independent risk factors of type 2 diabetes.
• In a multi-pollutant analysis, ultrafine particles, NO₂, noise at both most and least exposed façade and two proxies of lack of green space were all associated with higher risk of type 2 diabetes.
• The cumulative risk estimate of the multi-pollutant analysis was much higher than the risk estimate of any single pollutant. Read more...
