Epidemiology - correct answer study of the distribution (frequency, pattern) and determinants
(causes, risk factors) of health related states and events (not just diseases) in specified
populations.
Roles of epidemiology in public health: - correct answer - monitor health of a pop
-respond to emerging public health problems
-promote research and use of evidence based interventions
-evaluate the effectiveness of interventions
-findings provide foundations for public health policy
-set funding priorities for research intervention programs
which components of epidemiology describes who gets the disease, where people with the
disease are located and how these aspects of disease change over time? - correct answer
distribution
population - correct answer a group of people with a common characteristic in terms of
person, place, and time
crude mortality - correct answer number of deaths from all causes
age specific mortality - correct answer number of deaths from all causes in a specific age group
cause specific mortality - correct answer number of deaths from a specific cause
infant mortality - correct answer number of deaths of infants less than 1 year of age
prevalence rate - correct answer number of existing cases of disease
incidence rate - correct answer number of new cases of disease
disability - correct answer umbrella term for impairments, activity limitations, and
participation restrictions
disease frequency - correct answer quantification of the disease in the population: how often
does the disease occur
disease distribution - correct answer analysis of disease patterns: who, where, does it change
over time
epidemic - correct answer an increase in the number of cases of disease in a community,
above what is expected
endemic - correct answer a situation in a community in which there is a consistent elevated
rate of a certain disease

ANSWER S 2024.2025 ACTUAL EXAM GET IT RIGHT
pandemic - correct answer an epidemic that is widespread across a country, continent, or a
large populace, possibly world wide (ex. aids)
ratio - correct answer division of one number by another, numbers dont have to be related
proportion - correct answer numerator is subset of denominator, often expressed as a
percentage
rate - correct answer time is an intrinsic part of denominator, term is most misused
prevalence - correct answer number of existing cases of disease/ number in total population
(at a point or during a period of time)
incidence - correct answer number of new cases of disease that develop in the population at
risk during a specific time period
cumulative incidence - correct answer -number of new cases of disease/number in candidate
population (people who are at risk of getting disease) over a specified period of time
- estimates the probability or risk that a person will develop disease during a specified time
- used mainly for fixed populations
incidence rate - correct answer number of new cases of disease in the candidate population/
person time of observation
relationship between incidence and prevalence - correct answer -incidence decreases but
people are living longer with the disease= increased prevalence
- the incidence increases but the duration is short= decreased prevalence
- the incidence decreases and the duration is short= decreased prevalence
relative risk - correct answer [a/(a+b)]/[c/(c+d)]
or rate in exposed/rate in unexposed
Relative Risk (RR)=1.0 - correct answer no association between exposure and disease
RR=2.0 - correct answer two times the risk of disease in the exposed compared to the
unexposed
RR=1.6 - correct answer 1.6 times the risk of disease in the exposed compared to the
unexposed or 60% increased risk of disease in the exposed (1.6-1.0=.60=60%)
RR-.5 - correct answer .5 times or 1/2 the risk of disease in exposed compared to the
unexposed
odds ratio - correct answer -represents the odds that an outcome will occur given a particular
exposure, compared to the odds of the outcome occurring in the absence of that exposure

ANSWER S 2024.2025 ACTUAL EXAM GET IT RIGHT
- most commonly used in case-control studies; can also be used in cross sectional and cohort
studies
OR equation - correct answer (a/b)/(c/d)
which condition must be met in order for the Odds ratio to approximate the relative risk? -
correct answer the disease must be rare
ecological study (correlational) - correct answer -unit of analysis: population or groups
- exposure status: based on the population
- time can vary
ecological fallacy - correct answer making assumptions about the individual based on findings
at the level of the population
cross sectional - correct answer -time: snapshot in time
-population- individual level (selected without regard to exposure or disease status)
-measure: prevalence of disease
- measure of association: OR
-cannot determine cause and effect
case control - correct answer -disease is rate
-disease has a long induction and latent period
-little is known about the disease
- selection of the cases
-selection of controls
cohort study - correct answer a study in which two more groups of people that are free of
disease and that differ according to the extent of exposure (exposed and unexposed) are
compared with respect to disease incidence
Cohort study - correct answer -purpose: studies causes, preventions, and treatments for
diseases
- key feature: investigator selects subjects according to their exposure levels and follows them
for disease/outcome
-setting: trial not ethical, feasible, or too expensive. moderate or large effect expected. little
known about exposure and so can evaluate many effects of an exposure, exposure is rare.
