Study Notes

Epidemiology Study Notes

Primary Goal of Epidemiology: Study the distribution and determinants of health-related states in populations.
Descriptive Epidemiology Purpose: Describe the distribution of diseases by time, place, and person to generate hypotheses about disease causation. It observes and records health-related events to describe patterns.
Descriptive Epidemiology Variables: "Person" variables include age, etc. Other variables include time of year and location.
Analytic Epidemiology Objective: Establish a cause-and-effect relationship between exposures and health outcomes. Identify and quantify associations to determine causes.
Data Collection in Descriptive Epidemiology: Primarily used to generate hypotheses, not test them.
Analytic Epidemiology vs Descriptive: Analytic epidemiology tests hypotheses; descriptive epidemiology describes.
Case Definition: A specific instance of a disease or health condition in an individual, crucial for accurate counting. Includes clinical criteria and time/place but not treatment.
Caseness: The criteria that determine someone as a case of a specific disease.
Sensitivity of a Case Definition: Ability to identify true positive cases.
