Undiagnosed diabetes more common in richer areas

Researchers from the Australian National University, the Healthfirst Network and the University of Adelaide conducted the study, analysing general practice data on 9327 active patients aged 18 years or older. 

They used data from the North West Adelaide Health Survey (NWAHS) to develop a model to predict the total diabetes in a small area and then applied it to the data from general practices to predict the total level of expected diabetes.

The study revealed that lower socioeconomic areas had the highest prevalence of diagnosed diabetes.

However, the prevalence of undiagnosed diabetes was substantially higher in the least disadvantaged areas.
As expected, the prevalence of diagnosed diabetes was closely related to BMI and socioeconomic status. 

However, the level of undiagnosed diabetes followed a different pattern, being rare among the obese and more likely among those living in the areas of least disadvantage.
