The occurrence of disability and death due to a disease

Disability

How the disease is spread out or distributed in a population

Patterns or associations in the frequency of disease that may suggest ideas or hypotheses about the etiology of disease

Factors that occur more frequently among groups with the disease than among groups without the disease

Implies that the apparent association is actually the result of the data collection process

Measure the chances of developing a disease over a period of time. = # new cases of disease a year/ # of people in the at risk population

Relationship b/t incidence rate and mortality rate that estimates chances of dying from the disease

Numver of individuals who have a disease at a particular time divided by the number of individuals who could potentially have the disease = # living w/ a particular disease/ # in the at risk population

Epidemiologist look at the rates of disease in each age group then adjust for the age distribution of the population

Number of people in each age group

Investigations that use info on groups or population without having information on the specific individuals within the group

A difference in the groups being compared that makes a difference in the outcome being measured
