Sample Arab Board Community Medicine Part 1 Practice Questions

1In a diagnostic test study, 80 people with the disease test positive and 20 with the disease test negative. What is the sensitivity of the test?
A.50%
B.80%
C.20%
D.Cannot be calculated without the number of healthy people
Explanation: Sensitivity = TP / (TP + FN). Here TP = 80 and FN = 20, so sensitivity = 80 / (80 + 20) = 80%. Sensitivity measures the ability of a test to correctly identify those who truly have the disease.
2Which measure of disease frequency is most appropriate to describe the burden of a chronic non-communicable disease such as diabetes in a population at a single point in time?
A.Incidence rate
B.Cumulative incidence
C.Point prevalence
D.Attack rate
Explanation: Point prevalence measures the proportion of a population that has a condition at a single point in time and is well suited to chronic diseases of long duration such as diabetes. It reflects existing cases, capturing the overall burden.
3A cohort study reports that the risk of lung cancer is 0.20 in smokers and 0.05 in non-smokers. What is the relative risk?
A.0.25
B.4.0
C.0.15
D.15.0
Explanation: Relative risk = risk in exposed / risk in unexposed = 0.20 / 0.05 = 4.0. This means smokers have four times the risk of developing lung cancer compared with non-smokers in this study.
4Which study design is most appropriate for investigating the cause of a rare disease with a long latency period, such as mesothelioma after asbestos exposure?
A.Randomized controlled trial
B.Prospective cohort study
C.Case-control study
D.Cross-sectional study
Explanation: A case-control study is efficient for rare diseases because it starts with cases and selects controls, avoiding the need to follow a huge cohort for years. It allows estimation of the odds ratio as an approximation of relative risk.
5In a case-control study, the odds of exposure among cases is 60/40 and among controls is 30/70. What is the odds ratio?
A.0.29
B.3.5
C.2.0
D.1.5
Explanation: Odds ratio = (a/c)/(b/d) = (60 x 70)/(40 x 30) = 4200/1200 = 3.5. An odds ratio above 1 indicates the exposure is associated with increased odds of being a case.
6A screening test has high sensitivity but low specificity. What is the main consequence when it is applied to a population?
A.Many false negatives
B.Many false positives
C.Few people will be tested
D.The test will miss most true cases
Explanation: Low specificity means many people without the disease test positive, producing many false positives. High sensitivity ensures few true cases are missed, making such a test good for ruling out disease but requiring confirmatory testing.
7How does the positive predictive value (PPV) of a screening test change as the prevalence of disease in the screened population decreases, assuming sensitivity and specificity are constant?
A.PPV increases
B.PPV decreases
C.PPV stays the same
D.PPV becomes equal to sensitivity
Explanation: Predictive values depend on prevalence. As prevalence falls, the proportion of positive results that are true positives declines, so PPV decreases. This is why screening low-prevalence populations yields many false positives.
8Which criterion from the Wilson and Jungner principles must be met for a disease to be suitable for population screening?
A.The disease must be rare
B.There must be a recognizable latent or early symptomatic stage
C.Treatment should only begin after symptoms appear
D.The screening test should be expensive to ensure quality
Explanation: Wilson and Jungner require a recognizable latent or early symptomatic stage so that screening can detect disease before it would normally present, allowing earlier and more effective intervention.
9Lead-time bias in a screening program refers to which of the following?
A.Apparent improvement in survival caused only by earlier diagnosis without changing the date of death
B.Selective participation of healthier individuals in screening
C.Over-detection of slowly progressing disease that would never cause harm
D.Misclassification of disease status due to a faulty test
Explanation: Lead-time bias occurs when screening advances the time of diagnosis without postponing death, making survival time measured from diagnosis appear longer even though the patient does not live longer overall.
10A confounding variable in an epidemiological study is best defined as a variable that is:
A.On the causal pathway between exposure and outcome
B.Associated with both the exposure and the outcome but not on the causal pathway
C.Measured with random error only
D.Caused by the outcome of interest
Explanation: A confounder is associated with the exposure and is an independent risk factor for the outcome, while not being an intermediate step on the causal pathway. Confounding can distort the apparent exposure-outcome association.

Arab Board Community Medicine Part 1 Study Tips from Top Performers

1Master the core epidemiology and biostatistics formulas first, especially sensitivity, specificity, predictive values, relative risk, odds ratio and number needed to treat, because numerical questions are frequent and easy to score once the formulas are automatic.
2Practice distinguishing study designs and their characteristic biases, since many questions ask you to match a scenario to the right design or identify lead-time, recall, selection or confounding bias.
3Do not neglect the applied public-health topics such as immunization, screening criteria, outbreak investigation, environmental and occupational health and maternal and child health, as these provide reliable marks alongside the quantitative material.
