E)   race-specific age-adjusted prevalence.

Question 2

Accepted Answer

A) True 
 B)False

Question 3

For a chronic disease of low incidence and long duration, prevalence of the disease increases relative to incidence.

Accepted Answer

A) True 
 B)False

Question 4

Accepted Answer

A)   4000/500,000 × 1000
B)   4000/450,000 × 1000
C)   4000/950,000 × 1000
D)   4003/950,000 × 1000
E)   3997/950,000 × 1000

Question 5

Which of the following terms is expressed as a proportion (as distinguished from a ratio) ?

Accepted Answer

A)   Male Births / Female Births
B)   Female Births / Male + Female Births
C)   Female Births/ Male Births
D)   Female Births / Male + Female Births and Male Births / Female Births

Question 6

Calculation of the standardized mortality ratio is an example of the direct method of age adjustment.

Accepted Answer

A) True 
 B)False

Question 7

Expressing the burden or extent of some condition or attribute in a population:

Accepted Answer

A)   uses primarily incidence data.
B)   uses primarily prevalence data.
C)   could use both incidence and prevalence data equally.
D)   uses neither incidence data nor prevalence data.

Question 8

An epidemiologic survey of roller-skating injuries in Metroville, a city with a population of 100,000 (during the midpoint of the year) , produced the following data for a particular year:
Number of skaters in Metroville during any given month: 12,000
Roller-skating injuries in Metroville: 600
Total number of residents injured from roller-skating: 1800
Total number of deaths from roller-skating: 90
Total number of deaths from all causes: 900
The cause-specific mortality rate from roller-skating was:

Accepted Answer

A)   90/600 × 100,000.
B)   90/100,000 × 100,000.
C)   90/1800 × 100,000.
D)   90/900 × 100,000.

Question 9

The risk of acquiring a given disease during a time period is best determined by:

Accepted Answer

A)   the mortality rate from that disease in the 0-4 age group.
B)   a spot map that records all cases of the disease in the past year.
C)   the period prevalence for that disease during the past year.
D)   the incidence rate (cumulative incidence)  for that disease in a given period of time.
