Question 1
According to Raphael's framework, which of the following is the best example of
a vertical structure that indirectly influences population health?
A) The quality of housing in a low-income neighborhood
B) A provincial government's decision to increase income assistance rates
C) The presence of recreational facilities in a community
D) An individual's level of social support from family and friends
Rationale: Raphael distinguishes between horizontal and vertical structures based on their
proximity to health outcomes. Vertical structures are macro-level factors like social welfare
policies, taxation, and political decisions that indirectly shape health by influencing the
conditions in which people live. Income assistance rates set by government are a classic
example of a vertical structure. In contrast, housing quality, recreational facilities, and
social support are horizontal structures that have a more direct and immediate impact on
health.
,Question 2
What was the primary conclusion drawn by Rudolf Virchow following his investigation of
the typhus epidemic in Upper Silesia?
A) The epidemic was caused by poor hygiene and could be resolved by improving
sanitation
B) Preserving health requires "full and unlimited democracy" and radical social
measures
C) The disease was spread by contaminated water and required the removal of a pump
handle
D) Medical treatment alone was sufficient to control the outbreak if implemented
quickly
Rationale: Virchow's investigation of the typhus epidemic in Upper Silesia led him to
conclude that the outbreak was not merely a medical problem but a consequence of social
and political conditions, including feudalism, unfair tax policies, and lack of democracy. He
argued that preserving health required "full and unlimited democracy" and radical
measures rather than "mere palliatives." This is a foundational example of the social
determinants of health perspective in public health history.
Question 3
Which of the following best describes the social gradient in health as defined by
Marmot?
A) The difference in health outcomes between urban and rural populations
B) The graded association between socioeconomic status and population health,
where each step up the social hierarchy is associated with better health
,C) The relationship between gender and life expectancy
D) The impact of social support networks on recovery from illness
Rationale: Marmot's concept of the social gradient describes a stepwise relationship
between social position and health. It is not merely a dichotomy between rich and poor,
but a graded association where individuals at every level of the socioeconomic hierarchy
experience better health than those below them. This pattern persists across societies and
is a key concept in understanding health inequities.
Question 4
What does the differential exposure hypothesis propose regarding health
inequalities?
A) Lower socioeconomic groups are more vulnerable to the health effects of stressors
when they occur
B) Social inequalities lead to health disparities because certain groups are exposed
to more stressors and fewer resources than others
C) Differences in health behaviors fully explain the gap in health outcomes between
social classes
D) Genetic factors are the primary cause of health differences between population
groups
Rationale: The differential exposure hypothesis suggests that social inequalities result in
different levels of exposure to health-damaging conditions. Groups lower in the social
hierarchy face more stressors (e.g., financial insecurity, poor living conditions) and have
fewer protective resources. This is distinct from the differential vulnerability hypothesis,
which focuses on differential susceptibility to the effects of stressors once exposed.
, Question 5
A researcher is investigating the association between smoking and lung cancer. They
select a group of individuals with lung cancer and a comparison group without the
disease, then look back to compare their smoking histories. What type of study design is
this?
A) Prospective cohort study
B) Cross-sectional study
C) Ecological study
D) Case-control study
Rationale: A case-control study is an analytic study design that begins with individuals
who have the disease or outcome of interest (cases) and a comparison group without the
disease (controls). The researcher then looks backward (retrospectively) to compare the
odds of exposure between the two groups. This is an efficient design for studying rare
diseases or outcomes with long latency periods.
Question 6
What was the significance of John Snow's investigation of the cholera outbreak in
London?
A) He discovered the bacterium that causes cholera
B) He developed the first vaccine for cholera
C) He pioneered modern epidemiological methods by tracing the outbreak to a
contaminated water pump
D) He established that cholera was caused by the miasma theory
Rationale: John Snow is considered a founder of modern epidemiology for his systematic
investigation of the 1854 cholera outbreak in London. By mapping cases and identifying
