What term means the study of the distribution and determinants of disease frequency in human populations?
What term means the study of the distribution and determinants of disease frequency in human populations?
Epidemiology has been defined in several ways. One definition is the study of the nature, cause, control, and determinants of the frequency and distribution of disease, disability, and death in human populations. Friedman G et al.[111] 2003. Epidemiology is the study of disease occurrence in human populations.
What is distribution of disease in epidemiology?
In the definition of epidemiology, “distribution” refers to descriptive epidemiology, while “determinants” refers to analytic epidemiology. So “distribution” covers time (when), place (where), and person (who), whereas “determinants” covers causes, risk factors, modes of transmission (why and how).
What is meant by an epidemiologist?
An epidemiologist is a doctor who specializes in the patterns of diseases that spread between people. Epidemiologist comes from epidemiology, “the study of epidemics,” which has a Greek root: epidemios, “among the people.”
What is the aim of epidemiology?
The principal aim of epidemiology is to identify factors related to the occurrence of disease. Identification of these factors both causal ( causation) and risk factors, enable developing a rational basis for prevention ( epidemiology, prevention).
What is the best definition of epidemiology?
By definition, epidemiology is the study (scientific, systematic, and data-driven) of the distribution (frequency, pattern) and determinants (causes, risk factors) of health-related states and events (not just diseases) in specified populations (neighborhood, school, city, state, country, global). …
What are the different measures of disease frequency?
Measures of disease frequency including: Measures of effect including: The essence of epidemiology is to measure disease occurrence and make comparisons between population groups. The current section introduces the commonly used measures that help our understanding of the distribution of disease in a given population.
What does frequency mean in terms of Epidemiology?
Frequency refers not only to the number of health events such as the number of cases of meningitis or diabetes in a population, but also to the relationship of that number to the size of the population. The resulting rate allows epidemiologists to compare disease occurrence across different populations.
What are studies done to prevent the spread of disease?
These studies are done to establish programs that prevent and control the development and spread of disease and injury.
What do you mean by epidemiology of disease?
Epidemiology is the study of factors that influence the frequency and distribution of disease, injury and other health-related events and their causes in a defined human population. These studies are done to establish programs that prevent and control the development and spread of disease and injury.
What is the study of disease in a population?
Epidemiology itself is the study of disease in a population.with goals of determining the frequency and distribution of the disease as well as risk factors for the disease.
Frequency refers not only to the number of health events such as the number of cases of meningitis or diabetes in a population, but also to the relationship of that number to the size of the population. The resulting rate allows epidemiologists to compare disease occurrence across different populations.
When does a disease occur at a greater frequency than normal?
The term ______ refers to a disease occurring at a greater frequency than normal over more than one continent. A site where a pathogen is maintained as a source of infection is called a (n) ______.
Epidemiology is the study of factors that influence the frequency and distribution of disease, injury and other health-related events and their causes in a defined human population. These studies are done to establish programs that prevent and control the development and spread of disease and injury.
