Public Health Midterm Comprehensive Study Set

Define public health.

The science and art of preventing disease, prolonging life, and promoting health through organized efforts and informed choices of society, organizations, communities, and individuals.

Who gave the well-known 1920 definition of public health?

C. E. A. Winslow.

What is the central population-level goal of public health?

To maximize health benefits for populations while protecting fairness, rights, and the needs of different groups.

What is population health?

The health outcomes of a group of people and the factors—social, economic, environmental, and other—that influence those outcomes.

What is a population-based approach?

An approach designed to improve health across a whole population or group, not only treat one person at a time.

What is community health?

The health status and health-related conditions of people in a defined community.

What are organized community efforts?

Coordinated action by communities, governments, organizations, and individuals to protect and improve health.

What is prevention?

Action taken to stop disease or injury before it occurs, detect it early, or reduce its consequences.

What is health promotion?

Helping people and communities increase control over the factors that influence health and improve their well-being.

What is disease prevention?

Actions that reduce the likelihood of disease, identify it early, or limit complications and disability.

What is the main difference between public health and clinical medicine?

Public health primarily focuses on populations and prevention; clinical medicine primarily focuses on diagnosing and treating individual patients.

Does clinical medicine ever prevent disease?

Yes. Clinicians also vaccinate, screen, counsel, and prevent complications. The distinction is the primary focus, not an absolute separation.

Does public health ever provide services to individuals?

Yes. Public health programs may provide testing, vaccination, treatment, referrals, and other direct services as part of a population strategy.

Why does public health look beyond individual choices?

Health is also shaped by living conditions, resources, environments, policies, and access to services.

What is health surveillance?

Ongoing, systematic collection, analysis, interpretation, and use of health data to guide action.

What is an example of a population-level public health action?

Improving municipal drinking water so an entire community has lower exposure to contaminants.

What is an example of clinical medicine?

A clinician diagnosing an individual with pneumonia and prescribing appropriate treatment.

Why is prevention often preferable to treating disease after it occurs?

It can avoid illness, suffering, disability, and costs before they happen, though prevention does not eliminate the need for treatment.

What does "health is more than health care" mean?

Medical care matters, but housing, income, education, food access, safety, and other conditions also shape health.

What four tasks does the exam guide say to practice for each concept?

Define it, explain why it matters in public health, give an example when relevant, and connect it to other concepts.

What is John Graunt known for?

Vital statistics: using birth and death records to identify patterns in mortality.

Why is John Graunt important to public health?

His analysis showed how population data can reveal patterns that individual observations may miss.

What are vital statistics?

Numerical records of key life events such as births and deaths, used to understand population health.

What is Edwin Chadwick known for?

What was the 19th-century hygiene movement?

A reform movement focused on sanitation and unhealthy living conditions, especially as rapid urbanization created health problems.

Why did urbanization increase public health challenges during the hygiene movement?

Crowded living conditions, inadequate waste disposal, and contaminated water helped spread disease and create environmental hazards.

What does the term "sanitation movement" point to?

Efforts to improve water, sewage, waste management, housing conditions, and cleanliness to protect community health.

What is disease surveillance historically useful for?

Recognizing unusual patterns or outbreaks early enough to investigate and respond.

How did vaccination change public health?

It enabled prevention of infectious disease at population scale, not just treatment after people became ill.

What is the historical significance of public health boards?

They helped organize public responsibilities for sanitation, disease control, surveillance, and community health.

Why is blood banking a public health achievement?

Organized collection, storage, and distribution of blood can make lifesaving transfusions available to patients who need them.

What is the women's health movement associated with?

Greater access to health information, patient autonomy, attention to women's health needs, and challenges to unequal treatment.

How do the historical figures connect to modern public health?

They show recurring themes: use data, improve environments, organize systems, prevent disease, expand access, and challenge inequity.

How should you answer a historical-figure matching question?

Match the name to one distinctive contribution, such as Graunt-vital statistics or Drew-blood banking and racial equity.

What are the five steps in the public health prevention process?

Define the problem; identify risk factors; develop and test interventions; implement interventions; monitor their effectiveness.

Step 1: What does "define the health problem" mean?

Describe the health issue clearly, including who is affected, where, how often, and how serious it is.

Step 2: What does "identify risk factors" mean?

Determine exposures, conditions, or circumstances associated with a greater chance of the problem.

Step 3: What happens when developing and testing interventions?

Choose possible actions based on evidence and test whether they are feasible and effective in the community.

Step 4: What does implementing an intervention mean?

Put the selected program, policy, or action into practice.

Step 5: Why monitor interventions after implementation?

To see whether they work, reach intended groups, cause unintended effects, and need improvement.

What is primary prevention?

Prevents a health problem before it starts, such as vaccination, safer-road design, or reducing exposure to tobacco smoke.

What is secondary prevention?

Finds a disease or risk early to allow timely action, such as screening for high blood pressure.

What is tertiary prevention?

Limits complications, disability, or worsening after a condition has developed, such as rehabilitation after a stroke.

A vaccine is given before exposure to an infection. What level of prevention?

Primary prevention.

A screening test looks for disease before symptoms are noticed. What level?

Secondary prevention.

A program helps someone with diabetes prevent complications. What level?

Tertiary prevention, when the aim is to limit complications of established disease.

Why can the same disease be addressed at multiple prevention levels?

Prevention can stop new cases, detect existing cases early, and reduce complications in people who already have the condition.

What is compression of morbidity?

The goal of reducing the proportion or period of life spent with illness or disability, often by postponing disease until later life.

What is an example of infectious-disease control?

Contact tracing, testing, isolation when indicated, vaccination, and outbreak investigation.

What is emergency preparedness in public health?

Planning, training, coordination, and readiness for events such as disasters, epidemics, or other emergencies.

What is environmental health action?

Protecting health by addressing exposures such as unsafe water, air pollution, hazardous waste, or unsafe housing.

How do prevention and health promotion differ?

Prevention targets specific risks or health problems; health promotion more broadly builds conditions and abilities that support health. They often overlap.

What makes an intervention community-level?

It changes conditions, services, norms, resources, or policies affecting a community, rather than relying only on individual advice.

Why is evaluation part of prevention?

Without checking results, a program cannot reliably show whether it helped or how it should be improved.

Name the three core functions of public health.

Assessment, policy development, and assurance.

What does assessment mean in public health?

Monitor health, collect and analyze data, identify community needs, and investigate health threats.

What does policy development mean in public health?

Use evidence and community input to communicate, educate, plan, and develop policies to address health needs.
