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.
