More than half of Western Sydney's population is overweight and at risk of developing type 2 diabetes. The red areas on the map show the odds ratio of having diabetes is 1.5 in the areas including Western Sydney.
This is much higher that the odds ratio in the blue areas, which are as low as 0.5 in the beachside and northern suburbs. This data was compiled by University of Wollongong researchers Dr Thomas Astell-Burt and Dr Xiaoqi Feng from a 45 years and up population health study.
