Quick Answer: What Is The Epidemiological Triangle?

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 is the meaning of epidemiological?

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 two types of epidemiology?

Epidemiologic studies fall into two categories: experimental and observational.

Where does genetics belong in the epidemiological triangle?

The first element of the epidemiologic triad is the host organism – in human genetics, it is the person or human. The second element is the agent, which is either the genetic composition of the host, an infectious agent such as a virus, or an environmental factor such as smoking or cholesterol.

What are the 3 major types of epidemiological 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.

Why is the epidemiological triangle important?

The Epidemiologic Triangle The Epidemiologic Triangle is a model that scientists have developed for studying health problems. It can help your students understand infectious diseases and how they spread.

What are the 5 W’s of epidemiology?

The difference is that epidemiologists tend to use synonyms for the 5 W’s: diagnosis or health event (what), person (who), place (where), time (when), and causes, risk factors, and modes of transmission (why/how).

What are epidemiological determinants?

In the definition of epidemiology, “determinants” generally includes the causes (including agents), risk factors (including exposure to sources), and modes of transmission, but does not include the resulting public health action.

How do you break the epidemiologic triangle?

What are the three components of the epidemiological triangle?

A number of models of disease causation have been proposed. Among the simplest of these is the epidemiologic triad or triangle, the traditional model for infectious disease. The triad consists of an external agent, a susceptible host, and an environment that brings the host and agent together.

What are the 3 main elements of descriptive epidemiology?

In descriptive epidemiology, we organize and summarize data according to time, place, and person. These three characteristics are sometimes called the epidemiologic variables.

What is a descriptive epidemiological study?

Descriptive epidemiology uses observational studies of the distribution of disease in terms of person, place, and time. The study describes the distribution of a set of variables, without regard to causal or other hypotheses. Personal factors include age, gender, SES, educational level, ethnicity, and occupation.
