In 1997 it was estimated that 124 million of the world s billion total population had diabetes mellitus and it is projected that by 2010 this number will almost double to 221 million Amos McCarthy and Zimmet 1997 .

We also examine the epidemiology of impaired glucose regulation in people without overt diabetes.
