& ANSWERS 100% CORRECT!!
Epidemiology - ANSWERScience 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 - ANSWERfocuses on risk, data, demographics, and outcomes
Outcomes - ANSWEREnd result that follows an intervention
Aggregate - ANSWERdefined population
Community - ANSWERMultiple aggregates
Data - ANSWERCompiled information
Prevalence - ANSWERExistence of a disease.
Number of all cases of the disease
Incidence - ANSWERMeasures appearance of a disease over a period of time.
Risk Analysis - ANSWERCharacterization of the potential adverse health effects of
human exposures to environmental hazards
health disparities - ANSWERDifferences of health statuses between various
populations.
Sensitivity - ANSWERMeasures the proportion of actual positives that are correctly
identified as such (e.g., % of sick people who are correctly identified as having the
condition)
Surveillance - ANSWERCollection, analysis, and dissemination of data.
High-risk - ANSWERAn increased chance of poor health outcomes
Morbidity - ANSWERPresence of illness in a population
Mortality - ANSWERTracking deaths in an aggregate
, Vital statistics - ANSWERstatistics on live births, deaths, fetal deaths, marriages and
divorces
Cases - ANSWERCriterion used to make decisions whether the patient has a
disease or health event
Social Justice - ANSWERThe view that everyone deserves equal economic, political
and social rights and opportunities-including the right to good health
Inter-professional collaboration - ANSWERCollaborative action oriented toward a
common goal of improving quality & safety of patient care.
Involves responsibility, accountability, coordination, communication, cooperation,
assertiveness, mutual respect, and autonomy.
HP2020 - ANSWER4 goals:
1) attain high-quality lives preventable disease
2) achieve health equity, eliminate disparities, improve health of all groups
3) create social and physical environments that promote good health.
4) promote quality of life, healthy development, and health
Determinants of Care - ANSWERRange of personal, social, economic, and
environmental factors that influence health status
Specificity - ANSWERTrue 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) - ANSWERProbability that subjects with a positive
screening test truly have the disease
Epidemiological triangle - ANSWERTriad 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 - ANSWERExtra variable not accounted for and can ruin the
experiment.
Can introduce bias.
Study methods - ANSWERDescriptive.
Analytic.
Experimental.
