How common are MD?
Prevalence and Incidence
Nota:
Epidemiology - the study of the distribution of diseases, disorders or health-related behaviours in a given population.
!!! Determining the frequencies of MD.
Prevalence refers to the number of active cases in a population during any given period of time.
- usually expressed in %
Point prevalence
Nota:
Refers to estimated proportion of actual, active cases of the disorder in a given population at a given point in time.
It is like a snap shot of the disease in time.
Prevalence = Number of existing cases on a specific date ÷ Number of people in the population on this date.
1-year prevalence
Nota:
We would count anyone who experienced depression at any point in time throughout the entire year.
Therefore, it would include people who had recovered before the point of prevalence assessment as well as those whose disorders did not begin until after the point prevalence estimate was made.
Lifetime prevalence
Nota:
Number of people who have had a particular disorder at any time in their lives (even if they are now recovered)
Incidence
Nota:
Refers to the number of new cases that occur over a given period of time (typically 1 year). Incidence figures exclude preexisting cases. People who were ill before our starting date would not be included in the data.
Comorbidity
Nota:
Describes the presence of two or more disorders in the same person.
