◉ What is the study of epidemiology? Answer: refers to the systemic
surveillance, observation, experimentation while using a scientific
approach
◉ What is the distribution of epidemiology? Answer: refers to
person, place, and time
◉ What are the determinants of epidemiology? Answer: physical,
biological, social, cultural, economic and behavioral factors that
influence health
◉ Health-related states or events with epidemiology? Answer:
includes wellness, illness, disease, injury, impairments, and
disability
◉ Specified populations with epidemiology Answer: the
characteristics of who is healthy, who is at risk for the disease, and
who acquires the disease
,◉ Control of health problems and epidemiology Answer: the goal of
epidemiology is to identify factors associated with the development
of disease as well as factors that prevent illness
◉ What key features do we focus on with epidemiology? Answer:
populations and population health. Epidemiology is not focused on
providing direct care to individuals
◉ Does epidemiology focus on providing direct care to individuals
Answer: No, this is not the focus of epidemiology
◉ What are the core epidemiological functions? Answer:
Surveillance
Field investigations
Analytic studies
Evaluation
Linkages
Policy
◉ What type of science is epidemiology? Answer: it is a quantitative
science with measurement as a key feature
,◉ What does measurement focus on in epidemiology? Answer:
measurement focuses on the distribution and determinants of
health related states and events
◉ What are the 5 W's of epidemiology? Answer: What? When?
Where? Who? Why?
◉ What are the two components of epidemiology? Answer:
descriptive and analytic
◉ What is descriptive epidemiology? Answer: descriptive
epidemiology describes the
Distribution of health related events
Frequency and patterns of events
The 'who, what, and when'
The 'person, place and time '
◉ What is analytic epidemiology? Answer: analytic epidemiology
describes the
Determinants of health related events
The 'why'
The 'cause(s)'
, ◉ The role of CDC Answer: The CDC works 24/7 to protect America
from health, safety, and security threats, both foreign and in the US.
Whether diseases start at home or abroad, are chronic or acute,
curable or preventable, human error or deliberate attack, the CDC
fights disease and supports communities and citizens to do the
same. CDC increases the health security of our nation. As the
nation's health protection agency, CDC saves lives and provides
health information that protects our nation against expensive and
dangerous health threats, and response when these arise
◉ What is a variable? Answer: the thing that is being measured or
observed. It varies so it can assume different values
◉ Conceptual definition of a variable Answer: defines the concept
and is the dictionary definition
◉ Operational definition of a variable Answer: specifies how the
concept is measured. Describes the 'operations' used to obtain the
measurement
◉ Independent variables Answer: the variable that is manipulated
or varied by the researcher. Also known as the intervention,
treatment, or experimental variable. Thought to affect (cause) the
outcomes of interest. Usually only one independent variable in
experimental studies
