FA Review (Qns & Ans)
2025
1. What is the primary purpose of epidemiology?
a) To treat diseases
b) To diagnose medical conditions
c) To study the distribution and determinants of health-related
states or events
d) To develop pharmaceuticals
Correct ANS: c) To study the distribution and determinants
of health-related states or events
©2025
, Rationale: The primary purpose of epidemiology is to
understand the patterns and causes of health-related states or
events in specific populations.
2. Which measure of disease frequency refers to the number of
new cases of a disease in a specific population over a defined
period?
a) Prevalence
b) Incidence
c) Mortality rate
d) Case-fatality rate
Correct ANS: b) Incidence
Rationale: Incidence refers to the number of new cases of a
disease occurring in a specific population over a defined time
period.
3. What type of epidemiological study design compares
individuals with a specific disease to individuals without the
disease to identify potential risk factors?
a) Cohort study
©2025
, b) Case-control study
c) Cross-sectional study
d) Randomized controlled trial
Correct ANS: b) Case-control study
Rationale: Case-control studies compare individuals with a
specific disease (cases) to those without the disease (controls) to
identify potential risk factors.
Fill-in-the-Blank Questions
4. The __________ rate is the number of deaths due to a specific
disease divided by the total number of cases of that disease.
Correct ANS: case-fatality
Rationale: The case-fatality rate is the proportion of
individuals with a specific disease who die from that disease.
5. __________ refers to the occurrence of disease or health
condition at levels significantly higher than expected in a specific
population.
