About prevalence and incidence statistics:
The term 'prevalence' of Adolescent conditions usually refers to the estimated population
of people who are managing Adolescent conditions at any given time.
The term 'incidence' of Adolescent conditions refers to the annual diagnosis rate,
or the number of new cases of Adolescent conditions diagnosed each year.
Hence, these two statistics types can differ:
a short-lived 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.
