What is the best definition for epidemiology?

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 is epidemiology in simple words?

Section 1: Definition of Epidemiology. Epidemiology is the study of the distribution and determinants of health-related states or events in specified populations, and the application of this study to the control of health problems (1).

What is epidemiology example?

The term epidemiology is now widely applied to cover the description and causation of not only epidemic, infectious disease, but of disease in general, including related conditions. Some examples of topics examined through epidemiology include as high blood pressure, mental illness and obesity.

What is epidemiology in research?

Epidemiology is the science dealing with the spread and control of diseases and other factors relating to health in populations and other groups. Epidemiological information is used to identify and evaluate the risks of epidemic outbreaks of disease and to help prevent their spread or return.

What are the three components of epidemiology?

The epidemiologic triangle is made up of three parts: agent, host and environment.

What’s the purpose of epidemiology?

Epidemiology identifies the distribution of diseases, factors underlying their source and cause, and methods for their control; this requires an understanding of how political, social and scientific factors intersect to exacerbate disease risk, which makes epidemiology a unique science.

What are the basic concepts of epidemiology?

Epidemiology is based on two fundamental assumptions. First, the occurrence of disease is not random (i.e., various factors influence the likelihood of developing disease). Second, the study of populations enables the identification of the causes and preventive factors associated with disease.

What is the role of epidemiology?

Often called “Disease Detectives”, epidemiologists search for the cause of disease, identify people who are at risk, determine how to control or stop the spread or prevent it from happening again.

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.

Is epidemiology a good career?

Melissa Nolan, an assistant professor of epidemiology at the University of South Carolina School of Public Health, says epidemiology is a great field for an adult learner to enter after pursuing another career. Nolan – who has a master’s in public health with a concentration in epidemiology and global health and a Ph.

What are the major types of epidemiology?

Epidemiologic studies fall into two categories: experimental and observational.

What is an epidemiologist and how much do they make?

The U.S. Bureau of Labor Statistics reports that epidemiologists earn a median annual income of $70,820. Many epidemiologists will start with a salary at or around $46,870 (the median salary for the bottom 10% of wage earners), and can ultimately reach over $114,510 with experience.

What is exactly does epidemiology involve?

Population and epidemiology studies involve studying the health of populations -both at specific time points and over longer periods of time-to uncover patterns, trends, and outcomes that may be applicable to the general population.

What is epidemiology and what does an epidemiologist do?

Epidemiology. Epidemiology is the study and control of disease or injury patterns in human populations. When food poisoning or an influenza outbreak attacks a community, epidemiologist or “disease detectives”, are asked to investigate the cause of disease and control its spread.

Why is epidemiology so important?

Epidemiology is one important study that primarily identifies factors that pose one’s health at risk for certain diseases. This field of study also aids in determining approaches that can help treat and prevent onset of diseases at an optimal level.
