Health risks are measured using various epidemiological metrics:
Incidence Rate: The number of new cases of a disease in a specific population during a defined time period. Prevalence Rate: The total number of cases, both new and existing, of a disease in a population at a given time. Relative Risk: The ratio of the probability of an event occurring in the exposed group versus the non-exposed group. Odds Ratio: A measure of association between an exposure and an outcome, often used in case-control studies.
