PBHL 4613 MIDTERM EXAM QUESTIONS AND ANSWERS
Incidence and prevalence data have different applications in public health. Indicate by choosing the
appropriate option whether the use is for incidence or prevalence data.
Determining workload and planning the scope of facilities and manpower needs, particularly for chronic
disease. - CORRECT ANSWER✅✅This is a use of primarily prevalence data
The incidence of a disease is five times greater in men than in women, but the prevalence shows no sex
difference. The most likely explanation is that: - CORRECT ANSWER✅✅The duration of disease is
greater in women
Successful treatment programs that would shorten the duration of a disease primarily affect: - CORRECT
ANSWER✅✅The prevalence of the disease
Incidence and prevalence data have different applications in public health. Indicate by choosing the
appropriate option whether the use is for incidence or prevalence data.
The fundamental tool for etiologic studies of both acute and chronic diseases. - CORRECT
ANSWER✅✅This is a use of primarily incidence data
True or False? A prerequisite for using direct age adjustment is that the age-specific death rates in the
study population must be stable. - CORRECT ANSWER✅✅True
True or False? At the initial examination in the Framingham study, coronary heart disease was found in 5
per 1000 men ages 30-44, and in 5 per 1000 women ages 30-44. The inference that in this age group
men and women have an equal risk of getting coronary heart disease is incorrect because the data are
prevalence data and not incidence data. - CORRECT ANSWER✅✅True
Incidence and prevalence data have different applications in public health. Indicate by choosing the
appropriate option whether the use is for incidence or prevalence data.
To express the burden or extent of some condition or attribute in a population. - CORRECT
ANSWER✅✅This is a use of primarily prevalence data
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 any given month: 12,000
Roller skating injuries in metroville: 600
Total number of residents injured from roller skating: 1,800
Total number of deaths from roller skating: 90
Total number of deaths from all causes: 900
The proportional mortality ratio (%) due to roller-skating was: - CORRECT ANSWER✅✅90/900 x 100
The risk of acquiring a given disease during a time period is best determined by: - CORRECT
ANSWER✅✅the incidence rate (cumulative incidence) for that disease in a given period of time
The major disadvantage of crude rates is that: - CORRECT ANSWER✅✅they do not permit comparison
of population that vary in composition
True or False? E. coli O157:H7 is not considered a threat to the food supply of the United States. -
CORRECT ANSWER✅✅false
Which of the following activities characterizes a clinical approach (as opposed to an epidermiologic
approach)? - CORRECT ANSWER✅✅B. Description of specific signs and symptoms in a patient
Which of the following is not usually an aim of epidemiology? - CORRECT ANSWER✅✅E. To fund new
public health programs
In the Yearly Mortality Bill for 1632, consumption referred to: - CORRECT ANSWER✅✅C. tuberculosis
John Snow, author of Snow on Cholera: - CORRECT ANSWER✅✅A. was an early epidemiologist who
used natural experiments.
True or False? The study of diseases linked to harmful physical energy, such as ionizing radiation, would
be outside the scope of epidemiology. - CORRECT ANSWER✅✅false
