What are the key 6 characteristics of epidemiology?

It extracts six types of epidemiological characteristic: design of the study, population that has been studied, exposure, outcome, covariates and effect size.

What are the 3 main elements of the definition of epidemiology?

Epidemiology includes assessment of the distribution (including describing demographic characteristics of an affected population), determinants (including a study of possible risk factors), and the application to control health problems (such as closing a restaurant).

What are the four uses of epidemiology?

For community diagnosis of the presence, nature and distribution of health and disease among the population, and the dimensions of these in incidence, prevalence, and mortality; taking into account that society is changing and health problems are changing. To study the workings of health services.

What are the measures of epidemiology?

The most commonly used rates in epidemiology to evaluate morbidity are incidence and prevalence. These describe the frequency of disease during a given time period. Mortality rate, also a commonly used epidemiological rate, is a rate used to measure deaths and not morbidity.

What is the main purpose of epidemiology?

Epidemiology is the study of how often diseases occur in different groups of people and why. Epidemiological information is used to plan and evaluate strategies to prevent illness and as a guide to the management of patients in whom disease has already developed.

What is the focus of epidemiology?

Whereas epidemiology is the study of disease occurrence and transmission in a human population, epidemiological studies focus on the distribution and determinants of disease. Epidemiology may also be considered the method of public health—a scientific approach to studying disease and health problems.

What is the scope of epidemiology?

Epidemiology is a methodological discipline offering principles and practical guidelines for the creation of new quantitative evidence about health-related phenomena. Its aim is to contribute to knowledge in support of clinical medicine and community medicine.

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 are the two main goals of epidemiology?

The objectives of epidemiology include the following: to identify the etiology or cause of disease. to determine the extent of disease. to study the progression of disease.

What are the two types of epidemiology?

Epidemiologic studies fall into two categories: experimental and observational.

What are the 5 main objectives of epidemiology?

In the mid-1980s, five major tasks of epidemiology in public health practice were identified: public health surveillance, field investigation, analytic studies, evaluation, and linkages.

What are the key aspects of epidemiology?

Major areas of epidemiological study include disease causation, transmission, outbreak investigation, disease surveillance, environmental epidemiology, forensic epidemiology, occupational epidemiology, screening, biomonitoring, and comparisons of treatment effects such as in clinical trials.

What is the best definition for 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 10 duties of an epidemiologist?

What are the 3 major types of epidemiologic studies?

Three major types of epidemiologic studies are cohort, case-control, and cross-sectional studies (study designs are discussed in more detail in IOM, 2000). A cohort, or longitudinal, study follows a defined group over time.

What is an example of epidemiology?

Epidemiological studies measure the risk of illness or death in an exposed population compared to that risk in an identical, unexposed population (for example, a population the same age, sex, race and social status as the exposed population).

What is epidemiological concept?

Epidemiology is the study of the distribution and determinants of health-related states, conditions, or events in specified populations and the application of the results of this study to the control of health problems.
