ACCURATE ANSWERS
Absolute Risk correct answer - The overall incidence of the disease in a specified
population
- Calculated the same as the incidence proportion
Active immunity correct answer Body produces its own antibodies in response to
having been vaccinated or having a specific disease pathogen invade the body
Analytic Epidemiology describes the: correct answer - Determinants of health-
related events
- The 'why'
- The 'cause(s)'
Attributable Risk correct answer The amount of disease associated with a
causative factor in a specified population
BEINGS Model of Disease Causation correct answer B - Biological, Behavioral
E - Environmental
I - Immunological
N - Nutritional
G - Genetic
S - Services, Social, Spiritual
Bradford Hill Criteria for Causation correct answer - Strength of association
,- Consistency
- Specificity
- Temporal relationship
- Biological gradient
- Plausibility
- Coherence
- Analogy
- Experimental evidence
calculation of Risk correct answer Number of people who get the disease during a
designated period / Population of interest at the start of the designated time
period
Case correct answer An individual who has the disease, disorder, injury, health
behavior, or health event of interest
Case-Control Studies correct answer - Retrospective study design
- Studies people who already have the disease and looks backward at exposures
- Two groups of individuals are studied:
---- A group that has the disease under study (cases)
---- A group that does not have the disease under study (controls)
- Their health information is then examined to determine whether there are risk
factors that may be related to their current disease
Chain of Infection correct answer - Reservoir
- Portal of exit
, - Transmission
- Portal of entry
- Susceptible host
Cocooning correct answer - Used to protect infants from communicable diseases
- Only family and friends who are fully immunized are allowed to be around the
infant
Commonly used measures are correct answer - Risk Ratio or Relative Risk (RR)
- Odds Ratio (OR)
Confidence intervals are: correct answer calculated for risk and odds ratios
Core Epidemiological Functions correct answer 1. Surveillance
2. Field investigations
3. Analytic studies
4. Evaluation
5. Linkages
6. Policy
Cross-sectional studies correct answer - A population is studied at a single point in
time
- Participants are asked about their current disease state and their exposures to
certain factors
- Also known as prevalence studies
