MBI 131 MIAMI UNIVERSITY CERTIFIED QUALITY EXAM 1
QUESTIONS WITH CORRECT ANSWERS
Risk Factors
Characteristics or issues that increase the chances of
developing a disease
Objective of epidemiology
Identification of the cause(s) of diseases &/or risk factors
Disease Surveillance
Measurement of the extent of disease found in a population
(usually by counting cases or deaths)
Surveillance
Provides the data
Sporadic disease
A disease that occurs occasionally in a population/community
Endemic disease
,A disease that occurs at some constant or expected level in a
population/community
Epidemic disease
A disease that occurs in excess of the usual/expected level in
a population/community
Pandemic Disease
A worldwide epidemic disease
Health Status Indicators
-measurements of a community's health and its disease
burden
-allow comparisons among different communities
Health Adjusted Life Expectancy (HALE)
Number of years of health life expected, on average, in a given
population
Years of Potential Life Lost (YPLL)
Number of years lost when deaths occur before age 75
, Disability Adjusted Life Years (DALY)
A measure of the burden of disease that takes into account
premature death & loss of healthy life resulting from illness
and disability (the higher the DALY, the worse the disease is)
Epidemiological Rates
-birth rates, mortality rates, morbidity rates
-a measure of illness, injury, disability, or death in a given
population
-within a given time period
-expressed as "per unit of population"
Rate
Number of population events at a given time x the unit size
(per xxxx) population at risk for the event at that time
Why rates?
Disease cases, deaths, births, etc. Are put into the eli context
of when, where & who
-takes the size of the population into consideration
