The investigators hypothesize that the HbA1c shows a rising trend in pre-diabetics and normal
population with risk factors of developing type 2 DM. There is no known diabetes model for
predicting incident diabetes in an individual which takes into account the rate of change of
HbA1c (dx/dt). In such cases, the rate of change of HbA1c may give the physicians lead time
needed to implement the Diabetes Prevention Program measures.
