What is person place and time in epidemiology?

What is person place and time in 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 5 W’s of descriptive 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 3 main elements of descriptive epidemiology?

Descriptive epidemiology searches for patterns by examining characteristics of person, place, & time. These characteristics are carefully considered when a disease outbreak occurs, because they provide important clues regarding the source of the outbreak.

What are person variables in epidemiology?

Descriptive epidemiology describes the outbreak in terms of person, place and time. “Person” refers to socio-demographic characteristics of cases and includes variables such as age, ethnicity, sex/gender, occupation, and socioeconomic status.

Why is time important in epidemiology?

In either situation, displaying the patterns of disease occurrence by time is critical for monitoring disease occurrence in the community and for assessing whether the public health interventions made a difference. Time data are usually displayed with a two-dimensional graph.

What is descriptive epidemiology?

Descriptive epidemiology aims to describe the distributions of diseases and determinants. It provides a way of organizing and analyzing these data to describe the variations in disease frequency among populations by geographical areas and over time (i.e., person, place, and time).

What are descriptive epidemiological methods?

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.

What are descriptive studies in epidemiology?

Descriptive studies are observational studies which describe the patterns of disease occurrence in relation to variables such as person, place and time. They are often the first step or initial enquiry into a new topic, event, disease or condition.

What is descriptive epidemiology and what are the main domains?

Descriptive epidemiology evaluates frequency and pattern by examining the person, place, and time in relationship to health events. Descriptive epidemiology examines factors like age, education, socioeconomic status, availability of health services, race, and gender.

What defines 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.
