EPIDEMIOLOGY 2026 CORE EXAMS SETS QUESTIONS AND
ANSWERS MARKED A+
✔✔True or False? High firearm death rates and homicide rates are indicators of
adverse conditions within the community. - ✔✔True
✔✔The risk of acquiring a given disease during a time period is best determined by: -
✔✔the incidence rate (cumulative incidence) for that disease in a given period of time.
✔✔True or False? Calculation of the standardized mortality ratio is an example of the
direct method of age adjustment. - ✔✔False
✔✔Successful treatment programs that would shorten the duration of a disease
primarily affect: - ✔✔the prevalence of the disease
✔✔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:
The crude death rate for all causes was: - ✔✔900/100,000 × 100,000
✔✔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:
The proportional mortality ratio (%) due to roller-skating was: - ✔✔90/900 x 100
✔✔True or False? The crude death rate is defined as the number of deaths in a given
year divided by a reference population (during mid-point of the year) multiplied by
100,000. - ✔✔True
✔✔True or False? A prerequisite for using direct age adjustment is that the age-specific
death rates in the study population must be stable. - ✔✔True
✔✔True or False? Certain diseases can occur more than once in the same individual
during a stated period of time. Repeated cases of the disease have no effect upon
incidence rates. - ✔✔False
✔✔True or False? The point prevalence of a disease is defined as the number of
persons ill divided by the total number in the group at a point in time. - ✔✔True
✔✔The major disadvantage of crude rates is that: - ✔✔they do not permit comparison of
populations that vary in composition.
, ✔✔True or False? The proportional mortality ratio (%) is defined as the mortality due to
a specific cause during a time period divided by the mortality due to all causes during
the same time period times 100. - ✔✔True
✔✔True or False? One of three main purposes of descriptive epidemiology is to aid in
the creation of hypotheses. - ✔✔True
✔✔True or False? The three categories of descriptive epidemiologic variables are
person, place, and time. - ✔✔True
✔✔True or False? Developmental problems such as congenital birth defects occur
primarily late in life. - ✔✔False
✔✔Which of the following reasons might account for place variation in disease? - ✔✔all
of the above
✔✔True or False? The human biological clock phenomenon is linked to place variation
in diseases. - ✔✔False
✔✔Cyclic variations in the occurrence of disease may reflect: - ✔✔all of the above
✔✔True or False? WHO is a major source of information about worldwide international
variations in rates of disease. - ✔✔True
✔✔True or False? Nativity refers to place of origin of an individual. - ✔✔true
✔✔A null hypothesis is most similar to which of the following? - ✔✔negative declaration
✔✔A null hypothesis is most similar to which of the following? - ✔✔True
✔✔Descriptive epidemiology has the following characteristics (Choose the incorrect
option): - ✔✔allows causal inference from descriptive data
✔✔Which of Mill's four canons suggests that there is an association between frequency
of disease and the potency of a causative factor? - ✔✔concomitant variation
✔✔Descriptive epidemiology characterizes the amount and distribution of disease within
a population and enables the researcher to: - ✔✔b and c only
✔✔True or False? The National Health Survey consists of several distinct programs
conducted by the National Center for Health Statistics. - ✔✔true
