Prevalence of Type 2 diabetes and central adiposity in La Reunion Island, the REDIA Study.

La Reunion Island, a French overseas department in the Indian Ocean provides an example of rapid urbanisation and drastic changes in the way of life--from traditional to "westernized" lifestyle--over a few decades. To study the impact of this epidemiologic transition, a diabetes prevalence study was performed in 1999-2001. Fasting capillary blood glucose (cBG) and glycated hemoglobin (HbA1c) were systematically measured in a random sample of 3600 subjects aged 30-69 years.
