Health and Society
Domain 3: Health and Society
This domain tests the social, economic, legal, and ethical context of health. Items ask you to identify social determinants, explain disparities, distinguish public health from medical care, apply consent and confidentiality rules, or analyze how media and culture shape health behavior.
Social determinants and health equity
- Healthy People 2030 organizes social determinants of health into five domains: economic stability, education access and quality, health care access and quality, neighborhood and built environment, and social and community context.
- Health equity means fair opportunity to be healthy; equality means identical treatment. Because needs differ, equity often requires unequal distribution of resources.
- Upstream interventions change policies, environments, and income; downstream interventions provide treatment and individual services. Upstream action usually has larger population impact.
Health care system and policy
- Medicare covers people 65+, some younger people with disabilities, and end-stage renal disease. Medicaid is income-based and jointly funded by states and the federal government. CHIP covers low-income children. Employer-sponsored insurance and ACA marketplaces cover many others.
- Public health focuses on populations and prevention; medical care focuses on individuals and treatment.
- The ACA expanded coverage through marketplaces, Medicaid expansion in participating states, essential health benefits, coverage of preexisting conditions, and preventive services without cost sharing.
Ethics and law
- Core principles: autonomy, beneficence, nonmaleficence, justice. Informed consent requires capacity, disclosure, understanding, and voluntariness.
- HIPAA protects identifiable health information; FERPA covers school records. Minors generally need parental consent, but many states allow confidential care for STIs, mental health, or contraception.
- Mandated reporters must report suspected child abuse or neglect. Tarasoff-type duties may require warning identifiable third parties of serious threats.
Media, culture, and communication
- Media literacy analyzes source, purpose, audience, technique, and omitted information. Cultural competence means tailoring care to culture and language without stereotyping. Health literacy affects comprehension and navigation.
Worked example
A low-income neighborhood beside a freeway has high childhood asthma hospitalization rates. Upstream interventions include zoning and emissions policy, air-quality monitoring, and housing improvements. Downstream interventions include inhalers, asthma action plans, home environmental assessments, and case management. Reasoning: upstream reduces exposure at the population level; downstream manages disease in individuals. Both are needed, but only upstream changes incidence.
Traps that cost marks
- Equating health equity with treating everyone identically.
- Attributing disparities mainly to genetics or individual choices while ignoring environment and policy.
- Confusing Medicare (age/disability) with Medicaid (income).
- Assuming HIPAA covers all records; it does not cover school education records (FERPA) or employment records.
- Treating culture as a checklist rather than a dynamic context.
