Epidemiology Fundamentals
Covers measures of disease frequency, study designs, outbreak investigation, and causal reasoning.
Incidence measures:
A disease has an incidence of 50 per 100,000 per year and an average duration of 2 years. The approximate prevalence is:
A cohort study follows:
The relative risk (RR) of lung cancer for smokers vs. nonsmokers is 20. This means:
In a case-control study, the appropriate measure of association is:
An epidemic curve with a sharp peak suggests:
Confounding in epidemiology occurs when:
The number needed to treat (NNT) of 25 means:
Selection bias in a cohort study might occur when:
Hill's criteria for causation include all of the following EXCEPT:
Biostatistics for Public Health
Covers measures of central tendency, hypothesis testing, screening tests, and interpreting study results.
A screening test with high sensitivity will:
A screening test has 90% sensitivity and 80% specificity. In a population where 10% have the disease, what is the positive predictive value (PPV)?
A p-value of 0.03 means:
A 95% confidence interval for a mean difference is (2.1, 8.5). This means:
Type I error is:
When is the median a better measure of central tendency than the mean?
The power of a statistical test is:
Which measure describes the proportion of disease in a population that could be prevented by eliminating an exposure?
In a meta-analysis, a forest plot shows:
Adjusting for confounders in a multivariable regression model means:
Health Policy and Social Determinants
Covers health systems, health equity, social determinants, and policy analysis.
Social determinants of health include all of the following EXCEPT:
Health equity differs from health equality in that equity means:
In the United States, Medicare primarily serves:
Primary prevention aims to:
The 'inverse care law' states that:
A health impact assessment (HIA) is used to:
Which country spends the most on healthcare per capita while having worse health outcomes than many peer nations?
The 'tragedy of the commons' applies to public health when:
Community-based participatory research (CBPR) differs from traditional research by:
Structural racism affects health through:
Global and Environmental Health
Covers infectious disease control, environmental hazards, global health metrics, and international health systems.
Herd immunity is achieved when:
The basic reproduction number (R0) of a disease represents:
Disability-adjusted life years (DALYs) measure:
The epidemiological transition describes:
Particulate matter (PM2.5) air pollution is associated with:
The One Health approach recognizes that:
Antimicrobial resistance is accelerated by all of the following EXCEPT:
Lead poisoning primarily affects children through:
The WHO Framework Convention on Tobacco Control is significant because:
Climate change affects public health through all of the following pathways EXCEPT:

Study Recommendations
- Practice calculating and interpreting epidemiological measures (incidence, prevalence, relative risk, odds ratio, NNT) until they are second nature
- Analyze real public health case studies — COVID-19, Flint water crisis, opioid epidemic — using the frameworks you learn in class
- Learn to critically evaluate study designs by identifying potential sources of bias and confounding
- Connect social determinants of health theory to concrete policy interventions — understanding the 'so what' is essential
- Stay current with WHO and CDC reports to see how public health principles apply in practice
