Difference Between Descriptive and Analytic Epidemiology

Descriptive study types include the case report, cases series, and incidence studies. Analytic studies, on the other hand, should be performed if hypotheses exist for risk factors and diseases, and if these hypotheses need to be tested. Analytic studies fall into two categories: experimental and observational.

What is analytic epidemiology?

Thus, analytic epidemiology is concerned with the search for causes and effects, or the why and the how. Epidemiologists use analytic epidemiology to quantify the association between exposures and outcomes and to test hypotheses about causal relationships.

What is descriptive epidemiology?

Descriptive epidemiology is defined as epidemiological studies and activities with descriptive components that are much stronger than their analytic components or that fall within the descriptive area of the descriptive-analytic spectrum.

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 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.

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 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 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 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 the three most essential 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 the purpose of 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 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.

How does an epidemiologist describe the burden of disease?

Disease burden is the impact of a health problem as measured by financial cost, mortality, morbidity, or other indicators. It is often quantified in terms of quality-adjusted life years (QALYs) or disability-adjusted life years (DALYs).
