Epidemiology - ANSWER Science of public health.
Study of disease within populations & risk factors.
Risk factors are genetic, environmental, social,
cultural, or on some direct action by the individual.
Servers to find the "why" of a disease & then to
analyze the disease screening, treatment,
prevention, and monitoring.
population health - ANSWER focuses on risk, data,
demographics, and outcomes
Outcomes - ANSWER End result that follows an
intervention
Aggregate - ANSWER defined population
,Community - ANSWER Multiple aggregates
Data - ANSWER Compiled information
Prevalence - ANSWER Existence of a disease.
Number of all cases of the disease
Incidence - ANSWER Measures appearance of a
disease over a period of time.
Surveillance - ANSWER Collection, analysis, and
dissemination of data.
High-risk - ANSWER An increased chance of
poor health outcomes
Morbidity - ANSWER Presence of illness in a
population
Mortality - ANSWER Tracking deaths in an
aggregate
Vital statistics - ANSWER statistics on live births,
deaths, fetal deaths, marriages and divorces
Cases - ANSWER Criterion used to make
decisions whether the patient has a disease or
health event
, Social Justice - ANSWER The view that everyone
deserves equal economic, political and social rights
and opportunities-including the right to good health
Inter-professional collaboration - ANSWER
Collaborative action oriented toward a common
goal of improving quality & safety of patient care.

potential adverse health effects of human exposures
to environmental hazards
, health disparities - ANSWER Differences of
health statuses between various populations.
Sensitivity - ANSWER Measures the proportion of
actual positives that are correctly identified as such
(e.g., % of sick people who are correctly identified
as having the condition)
Specificity - ANSWER True negative rate
Measures actual negatives that are correctly
identified as such (e.g., % of healthy people who
are correctly ID's as not having the condition)
Positive Predictive Value (PPV) - ANSWER
Probability that subjects with a positive screening
test truly have the disease
Epidemiological triangle - ANSWER Triad with
an external agent, host, and an environment that
cause the disease.
Environmental factors and genetics play a role.
Disease transmitted directly or indirectly.
Outright symptoms or subclinical disease.
Confounding Variable - ANSWER Extra variable
