The word 'prevalence' of Impaired glucose tolerance usually means the estimated population
of people who are managing Impaired glucose tolerance at any given time (i.e. people with Impaired glucose tolerance).
The term 'incidence' of Impaired glucose tolerance means the annual diagnosis rate,
or the number of new cases of Impaired glucose tolerance diagnosed each year (i.e. getting Impaired glucose tolerance).
Hence, these two statistics types can differ:
a short disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
For more information see about prevalence and incidence statistics.
