,Epidemiology - ANSWERstudy 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: - 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? -
ANSWERdistribution
population - ANSWERa group of people with a common characteristic in terms of
person, place, and time
crude mortality - ANSWERnumber of deaths from all causes
age specific mortality - ANSWERnumber of deaths from all causes in a specific age
group
cause specific mortality - ANSWERnumber of deaths from a specific cause
infant mortality - ANSWERnumber of deaths of infants less than 1 year of age
prevalence rate - ANSWERnumber of existing cases of disease
incidence rate - ANSWERnumber of new cases of disease
disability - ANSWERumbrella term for impairments, activity limitations, and participation
restrictions
disease frequency - ANSWERquantification of the disease in the population: how often
does the disease occur
disease distribution - ANSWERanalysis of disease patterns: who, where, does it change
over time
epidemic - ANSWERan increase in the number of cases of disease in a community,
above what is expected
, endemic - ANSWERa situation in a community in which there is a consistent elevated
rate of a certain disease
pandemic - ANSWERan epidemic that is widespread across a country, continent, or a
large populace, possibly world wide (ex. aids)
ratio - ANSWERdivision of one number by another, numbers dont have to be related
proportion - ANSWERnumerator is subset of denominator, often expressed as a
percentage
rate - ANSWERtime is an intrinsic part of denominator, term is most misused
prevalence - ANSWERnumber of existing cases of disease/ number in total population
(at a point or during a period of time)
incidence - ANSWERnumber of new cases of disease that develop in the population at
risk during a specific time period
cumulative incidence - 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 - ANSWERnumber of new cases of disease in the candidate population/
person time of observation
relationship between incidence and prevalence - 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 - ANSWER[a/(a+b)]/[c/(c+d)]
or rate in exposed/rate in unexposed
Relative Risk (RR)=1.0 - ANSWERno association between exposure and disease
RR=2.0 - ANSWERtwo times the risk of disease in the exposed compared to the
unexposed
RR=1.6 - ANSWER1.6 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 - ANSWER.5 times or 1/2 the risk of disease in exposed compared to the
unexposed
