Document Summary
Unit 4 measures of association & disease frequency. Identify, define and understand the strengths and weaknesses of various ways to measure disease and health within populations as well as the relationship between exposures and outcomes of interest. Calculate and interpret common measures of association (risk difference, attributable risk exposed, population attributable risk, relative risk, odds ratio) and measures of disease frequency (prevalence, risks, rates) used in epidemiological research. There are many different ways we can measure and describe disease and health outcomes: Counts a simple representation of a number of events/outcomes of interest: e. g. , 1,3, 75, 2000. Ratios dimensionless, unit-less comparison of one count to another: e. g. Proportions ratio where a number is included in the denominator: e. g. Risks proportions that express the probability that something will occur: e. g. Let"s practice describing a situation using different measures and a fictitious example.
