What is the definition of epidemiology?

What are the three elements of epidemiology?

What is the epidemiological triangle?
A framework consisting of Host, Agent, and Environment.
What are the two types of surveillance in epidemiology?
Active surveillance and passive surveillance.
What is the purpose of the web of causation framework?
To illustrate the complexity of how illness, disease, and injury are determined by
multiple causes.
What is the ecological model in epidemiology?
A model that includes biological and behavioral influences to design health promotion
interventions.
What are the seven questions for an epidemiology investigation?
Who, what, when, where, why, how, and how long?
What is the significance of John Snow's investigation?
He identified the Broad Street pump as the source of a cholera epidemic, leading to
improved sanitation.
What are the three critical areas of environmental risk factors?
Safe air quality, safe water supplies, and safe soils.
What does genetic epidemiology seek to understand?
The heritability of factors impacting the development of illness and disease.
What is the difference between cohort and case-control study design?
, Cohort studies follow a group over time, while case-control studies compare individuals
with a condition to those without.
What is causality in epidemiology?
A stimulus or action that results in an effect or outcome.
What are the components of the epidemiological triangle?
Host, Agent, and Environment.
What is the role of biostatistics in epidemiology?
To analyze epidemiological data and understand health outcomes.
What is the sanitary phase in the science of epidemiology?
Illness related to foul emanations from soil, air, and water.
What is the infectious disease phase?
Linking individual organisms to specific diseases.
What is the risk factor phase in epidemiology?
Linking exposures to occurrences of injury or disease to identify risk factors.
What is the importance of time in epidemiological investigations?
It helps determine when individuals came into contact with risk factors.
What is the primary focus of nursing in relation to epidemiology?
Health promotion, disease prevention, and health education.
What is the significance of the Broad Street water pump in epidemiology?
It was identified by John Snow as a source of cholera deaths, leading to public health
reforms.
What are the implications of genetic testing in epidemiology?
It leads to individual decision-making rather than population-level insights.
What is the role of public health professionals in managing environmental risks?
They use education, engineering, and enforcement to reduce health risks.
What is the relationship between the epidemiological triangle and disease?
It applies to all diseases, both communicable and noncommunicable.
What does the term 'agent' refer to in the epidemiological triangle?
Biological, chemical, nutritive, physical, or psychological factors that can cause disease.
What is the importance of demographic factors in epidemiology?
They help identify which groups of individuals are affected by health issues.
What does the term 'host' refer to in epidemiology?
The susceptible human or animal affected by a disease.
What is demography?
The study of person-related variables compared over time to establish trends within a
population.
What is life expectancy?
The average number of years a person born in a given country would live if mortality
rates at each age remained constant.
What are common sources of demographic data?
Census, community level data, and national surveys.
What is biostatistics?
The analysis of data related to human organisms, used in public health science and
other biological sciences.
How is the mean calculated?
By summing all values and dividing by the total number of values in the set.
