What is the main purpose of epidemiology?

What are the 3 levels of prevention?
- improving the overall health of the population (primary prevention)
- improving (secondary prevention)
- improving treatment and recovery (tertiary prevention).
What are the 3 types of risk factors?
- Major risk factors – Research has shown that these factors significantly increase the risk of heart and blood vessel (cardiovascular) disease.
- Modifiable risk factors – Some major risk factors can be modified, treated or controlled through medications or lifestyle change.

What are the two main goals of epidemiology?
Aims of Epidemiology
There are two groups of aims: first,
to describe the distribution, the pattern, and the natural history of disease in the general population
, and second, to identify factors that may be causal in a disease process, and to evaluate strategies for the control, management, and prevention of a disease.
