relationship between descriptive and analytical epidemiology

Overview of Analytic Studies As you may recall, descriptive studies are useful if very little is known about a new disease or condition. They can be used to generate hypotheses on risk factors and causes of disease. Analytic studies, on the other hand, are usually larger and more complex than descriptive studies.

What is the difference between descriptive epidemiology and analytical epidemiology?

Generally speaking, descriptive studies deal with the “what” questions, for example, describing “what happened” in terms of disease occurrence, while analytic studies ask the “why” questions, for example, why some people develop disease and others don't.

What is the difference between a descriptive study and an analytic study?

Descriptive studies involve detailed investigations of individuals in order to improve knowledge of disease. Descriptive studies often have no prior hypotheses and are opportunistic studies of disease whereas analytical studies are used to test hypotheses by selection and comparison of groups.

What are analytical studies in epidemiology?

In summary, the purpose of an analytic study in epidemiology is to identify and quantify the relationship between an exposure and a health outcome. The hallmark of such a study is the presence of at least two groups, one of which serves as a comparison group.

What is descriptive epidemiology?

Descriptive epidemiology provides a way of organizing and analyzing data on health and disease in order to understand variations in disease frequency geographically and over time and how disease varies among people based on a host of personal characteristics (person, place, and time).

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 are the 3 main elements of descriptive epidemiology?

Descriptive epidemiology covers time, place, and person. Compiling and analyzing data by time, place, and person is desirable for several reasons.

What is an example of a descriptive study?

For example, an apparel brand that wants to understand the fashion purchasing trends among New York buyers will conduct a demographic survey of this region, gather population data and then conduct descriptive research on this demographic segment.

What are the types of descriptive epidemiological studies?

Three of the types of descriptive epidemiologic studies are in- dividual case reports, case series, and cross-sectional studies (e.g., a survey of a population). Case reports and case series are among the most basic types of descriptive studies.

What is an example of descriptive epidemiology?

A hypothetical example of a descriptive epidemiological study is the investigation of a group of workers in a factory who have what is suspected to be environmentally acquired lupus.

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 skills do you need to be an epidemiologist?

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.
