, Question 1
A cohort study reports a risk ratio of 2.5 (95% CI: 1.8-3.4) for the association
between a novel exposure and disease. Which statement best reflects the
correct interpretation regarding causal inference?
A. The exposure causes the disease in 2.5 times as many people as those
unexposed.
B. The association is statistically significant, but causality requires ruling
out confounding, bias, and reverse causation.
C. The 95% CI excludes 1.0, proving a causal relationship.
D. The risk ratio indicates a 2.5% increase in disease risk attributable to
the exposure.
Correct Answer: B - The association is statistically significant, but
causality requires ruling out confounding, bias, and reverse
causation.
RATIONALE
A risk ratio of 2.5 with a CI excluding 1.0 indicates a statistically
significant association, not proof of causation. Causal inference
requires consideration of Bradford Hill criteria, confounding, bias, and
temporality. Options A, C, and D misinterpret the measure or
overstate certainty.
Question 2
Which policy approach best exemplifies a 'health in all policies' (HiAP)
strategy to reduce obesity prevalence at the population level?
A. Subsidizing bariatric surgery for individuals with BMI >40.
B. Mandating calorie labeling in chain restaurants only.
C. Integrating health impact assessments into urban planning,
transportation, and agricultural subsidies.
D. Launching a public awareness campaign on diet and exercise.
Correct Answer: C - Integrating health impact assessments into
Page 2
,urban planning, transportation, and agricultural subsidies.
RATIONALE
HiAP requires systematic consideration of health impacts across all
sectors, not just health care or individual behavior. Urban planning,
transportation, and agriculture policies shape food environments and
physical activity. Options A, B, and D are narrower, downstream, or
sector-specific.
Question 3
A researcher wants to assess the burden of disease attributable to a specific risk
factor in a population. Which metric is most appropriate to compare the impact
of different risk factors?
A. Odds ratio
B. Population attributable fraction (PAF)
C. Relative risk
D. Number needed to treat (NNT)
Correct Answer: B - Population attributable fraction (PAF)
RATIONALE
The population attributable fraction quantifies the proportion of
disease in a population that could be eliminated if the risk factor were
removed, allowing comparison across risk factors. Odds ratio and
relative risk measure association strength, while NNT is a clinical
intervention metric.
Question 4
Which ethical principle is most directly challenged when a public health
agency mandates isolation of individuals with a highly infectious disease
against their will?
A. Beneficence
B. Autonomy
Page 3
, C. Justice
D. Nonmaleficence
Correct Answer: B - Autonomy
RATIONALE
Mandatory isolation restricts individual liberty and self-determination,
directly challenging autonomy. While beneficence and
nonmaleficence may justify the action, and justice concerns fair
distribution, the primary conflict is with autonomy. Public health
ethics often invokes the harm principle to justify such restrictions.
Question 5
In a randomized controlled trial, the intention-to-treat (ITT) analysis is
preferred over per-protocol analysis primarily because it:
A. Increases statistical power by including all participants.
B. Preserves the benefits of randomization and reduces bias from
non-compliance.
C. Provides a more accurate estimate of the biological efficacy of the
treatment.
D. Eliminates confounding by indication.
Correct Answer: B - Preserves the benefits of randomization and
reduces bias from non-compliance.
RATIONALE
ITT maintains randomization, preventing selection bias from
post-randomization exclusions. It estimates the effect of assignment,
not treatment received, which is more pragmatic. Per-protocol can
overestimate efficacy and introduce bias. ITT does not eliminate
confounding by indication, which is addressed by randomization.
