course of a disease: how often a disease occurs, how likely it is to be present currently, and what happens once it occurs

distribution of disease: who gets the disease? where are they located? when does the disease occur?

incidence rates useful for finding the etiology

understanding of distribution

epidemiologist investigate "persons" and "place" to figure out

group associations can suggestions about the etology of a disease

Healthography: reflect the importance of geographic location to health

risk indicators

real or artifactual?

differences or changes in the interest of identifying the disease

etiology

cause is associated with the effect at the individual level

cause precedes the effect in time

altering the cause alters the effect

3 kinds of ivestigations: cohort studies, case-control studies, and randomized control trials

efficacy implies that an intervention works

supportive criteria for etiology

strength of the relationship

dose response rleationship

consistency of the relationship

relative risk:

implication of contributory cause

necessary cause

contributory cause

how do we get the job done?

primary interventions

secondary interventions

tertiary interventions

evauation
