Type 2 diabetes rate 86% higher under flightpath

The epidemic of type 2 diabetes across the world shows limited signs of abating. There are many documented risk factors, obesity, sugar intake and family history.

Over the past few years, a number of studies have looked into the effect of noise levels on diabetes. Almost all have concluded that higher noise levels (particularly in home environments) contribute to incidence of type 2 diabetes.

Studies in Sweden, UK and a meta study looking at a total of 9 relevant studies have all come up with the same basic conclusion.

Its all those damn Aussies are making me sick

In Denmark, they determined that incidence levels are increased by around 10-11%. In the UK, they have quoted 85% higher levels of type 2 diabetes (this is a staggering result, but maybe we need to wait for peer review before taking this as gospel:

  • The meta-study concluded that exposure to higher noise levels in the residential environment were 22% higher to have type 2 diabetes (95% confidence) for noise levels >60dBa compared with noise levels of <64dBa (note the overlap - which means the impact of noise is higher than stated).

  • The same meta-study concluded no material difference in diabetes levels for exposure to >85 dBa in the work environment.

The trend however is clear. Noise makes you sick. For me, working against a family history of type 2 diabetes, and always struggling to stay under the 25 BMI threshold, here is one more factor I need to take into account.
