Quiz: Health Equity and Disease Prevention

Test your understanding of health disparities, physical activity access, and chronic and infectious disease prevention with these review questions.

1. What is a "health disparity," as defined in the chapter?

  1. Any health difference caused entirely by an individual's personal choices
  2. A measurable, avoidable difference in health outcomes between groups that arises from unequal social, economic, and environmental circumstances
  3. A medical term with no connection to income or neighborhood conditions
  4. A difference in willpower between two communities
Show Answer

The correct answer is B. The chapter defines health disparities as measurable, avoidable differences in health outcomes between groups that arise from unequal social, economic, and environmental circumstances, not from individual behavior alone. The example of two students living ten miles apart with very different neighborhood conditions illustrates that these gaps are built by systems, not chosen by residents.

2. How does the chapter use the historical practice of redlining to illustrate systemic inequity?

  1. Redlining had no lasting effects once the practice legally ended
  2. Redlining only affected which grocery stores offered discounts
  3. Redlining is presented as a personal choice made by individual homeowners
  4. Redlining systematically denied loans in certain neighborhoods, suppressing investment so severely that those areas still show higher rates of heat exposure, asthma, and limited green space today
Show Answer

The correct answer is D. The chapter explains that redlining denied mortgage loans in specific, often Black and immigrant neighborhoods, suppressing investment for decades. This history connects directly to present-day measurable disparities like heat exposure, asthma rates, and limited green space, showing how policy decisions from decades ago still shape health opportunity today.

3. What is "community (herd) immunity"?

  1. A protective effect where transmission chains break down when enough of a community is vaccinated, even for people who cannot be vaccinated for medical reasons
  2. A guarantee that no one in a vaccinated community can ever become infected
  3. A term describing only individual immune system strength
  4. A sanitation practice unrelated to vaccination
Show Answer

The correct answer is A. The chapter describes community immunity as the effect where, when enough of a community is vaccinated, transmission chains break down even for the small number of people who cannot be vaccinated for medical reasons. This works because vaccination targets the new host's immune defense point in the transmission chain.

4. How does the chapter distinguish chronic diseases from infectious diseases?

  1. Infectious diseases always take decades to develop, while chronic diseases develop in days
  2. Chronic diseases are never influenced by environmental factors
  3. Chronic diseases tend to develop over years from cumulative behavioral and environmental exposures, while infectious diseases are caused by pathogens transmitted between people or from contaminated sources
  4. There is no meaningful distinction between the two categories
Show Answer

The correct answer is C. The chapter separates chronic diseases, such as heart disease and type 2 diabetes, which develop over years from cumulative exposures, from infectious diseases, such as influenza or foodborne illness, which are caused by pathogens transmitted between people or from contaminated sources. It also notes the same social conditions can raise the risk of both categories simultaneously.

5. A student wants to go for a run at 6 p.m. in December, when it gets dark at 5 p.m., in a neighborhood park with no streetlights. Which combination of strategies from the chapter best addresses this specific scenario?

  1. Running alone at the darkest, least populated time to avoid other people
  2. Using the buddy system and choosing a well-lit, populated indoor alternative like a school gym instead
  3. Skipping physical activity entirely until summer arrives
  4. Wearing dark clothing to stay unnoticed while running alone
Show Answer

The correct answer is B. The chapter's safe-participation strategies include using the buddy system, choosing timing deliberately, and knowing indoor alternatives like school gyms or community centers. Given the darkness and lack of streetlights in this scenario, combining the buddy system with an indoor alternative directly addresses the specific hazard rather than running alone in the dark.

6. A student wants to reduce their long-term chronic disease risk but has limited time for exercise due to a part-time job. Based on the chapter's prevention strategies, which additional strategy is often overlooked despite being a low-barrier option?

  1. Ignoring sleep and stress entirely since they don't affect chronic disease
  2. Skipping routine screening since it doesn't prevent disease directly
  3. Avoiding all forms of physical activity if time is limited
  4. Prioritizing stress management and sleep, and keeping up with routine screening, since both are independently linked to disease risk and require no extra time for a workout
Show Answer

The correct answer is D. The chapter's model justification for a time-constrained student highlights that screening and sleep are often the most overlooked, lowest-barrier strategies. Chronic stress and poor sleep are independently linked to elevated blood pressure and inflammation, and routine screening catches developing disease early, both without requiring dedicated exercise time.

7. A school responds to a new respiratory virus outbreak by improving classroom ventilation only, without addressing vaccination rates. According to the chapter's transmission chain reasoning, what is the likely limitation of this approach?

  1. Ventilation targets person-to-person spread, but exposed unvaccinated individuals can still become ill since the new host's immune defense point remains unaddressed
  2. Ventilation has no effect on respiratory virus transmission at all
  3. This approach fully eliminates transmission risk since ventilation addresses every point in the chain
  4. Vaccination and ventilation address the exact same transmission point, making one of them redundant
Show Answer

The correct answer is A. The chapter explains that improving ventilation targets the person-to-person spread point in the transmission chain, but vaccination targets a separate point: the new host's immune defense. Using only ventilation still allows illness in unvaccinated individuals who are exposed, since good airflow alone doesn't prepare anyone's immune system in advance.

8. A city council votes to rezone a neighborhood to require sidewalks and green space in all new development. According to the chapter's table of change levels, what type of action is this?

  1. An individual-level action taken by a single resident
  2. A community-level action organized by neighbors
  3. An institutional action taken by a school or local agency
  4. A policy-level action, since it involves a city council changing zoning requirements
Show Answer

The correct answer is D. The chapter's table of change levels identifies rezoning to require sidewalks and green space as a policy-level action, typically carried out by city councils or state legislatures. This is distinct from individual actions like choosing to walk, or institutional actions like a school adding a walking-school-bus program.

9. Why does the chapter emphasize that categories like economic stability, food access, and health care access "compound" rather than operate in isolation?

  1. Because a family with unstable income is more likely to also live in a neighborhood with fewer safe places to be active and limited access to fresh food and a nearby clinic, producing larger combined gaps in health outcomes
  2. Because each category always affects health independently with no relationship to the others
  3. Because only one category actually matters for health outcomes, and the others are irrelevant
  4. Because compounding only applies to infectious disease, not chronic disease
Show Answer

The correct answer is A. The chapter explains that these categories interact rather than operate separately: unstable income is linked to living in a neighborhood with fewer safe places to be active and less access to fresh food and health care. It is this compounding, not any single factor alone, that produces large and persistent health gaps between communities.

10. Evaluating a lower-income neighborhood's physical activity infrastructure using the chapter's comparison data (lower park acreage, fewer sidewalks, fewer recreation programs, lower reported safety), what is the strongest conclusion?

  1. Residents in this neighborhood are less motivated to be active than residents elsewhere
  2. The infrastructure gaps reflect resident preference rather than zoning and investment decisions
  3. The gap reflects unequal access shaped by zoning and investment decisions, not a difference in how much residents want to be active, and it compounds into higher chronic disease risk
  4. No physical activity is possible in this type of neighborhood under any circumstances
Show Answer

The correct answer is C. The chapter's chart explicitly annotates that gaps like these are shaped by zoning and investment decisions, not resident preference, and connects unequal physical activity access directly to higher chronic disease risk, since regular activity is one of the strongest protective factors against several chronic conditions.
