/.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.
Involves responsibility, accountability, coordination, communication, cooperation,

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 - Answer-Range of personal, social, economic, and
environmental factors that influence health status
/.Risk Analysis - Answer-Characterization of the 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 not accounted for and can ruin the
experiment.
