Study Notes

Epidemiological Variables and Disease Distribution

The main epidemiological variables used to estimate the distribution of a disease in a population are person, place, and time.

Causal Association

A necessary condition for determining that an observed association is causal is temporality.

Analytical Epidemiology

Analytical epidemiology aims to identify the causes of health problems and evaluate the effectiveness of interventions.
Biases, confounding, and chance may lead to causation in analytical epidemiology.
Selection bias refers to non-random differences between comparison groups in analytical epidemiology.

Descriptive Epidemiology

The main focus of descriptive epidemiology is to describe the distribution of a disease in a population.
Descriptive epidemiology estimates the frequency and distribution of a disease in a population.
The main variables used in descriptive epidemiology are person, place, and time.

Types of Epidemiology

There are two main types of studies in epidemiology: descriptive and analytical.
Analytical epidemiology raises and tests hypotheses about the causal relationships between health phenomena and their determinants.

Definition of Epidemiology

The study of the occurrence and distribution of health-related states or events in specified populations, including the study of the determinants influencing such states, is a definition related to the concept of epidemiology.
