SMU SDH211: Detailed Study Notes on Social Determinants of Health and Illness

Social Determinants of Health and Illness is a core lens for understanding why health outcomes differ between individuals and groups. In SDH211, the focus extends beyond clinical care to the social, economic, environmental, and political conditions that shape risk, access, and health behaviours. In the South African context—where inequality, unemployment, spatial segregation, and uneven service delivery influence everyday life—social determinants help explain patterns of illness that otherwise appear “mysterious” when viewed only through biology and healthcare access. These study notes provide a detailed, South Africa–relevant, course-aligned guide to key concepts, frameworks, and applied examples.

Understanding SDH211: Core Concepts, Scope, and South African Relevance

Social determinants of health (SDOH) refer to the conditions in which people are born, grow, live, work, and age, including the systems that shape daily life. Social determinants of illness—often discussed alongside SDOH—emphasise the pathways through which social conditions produce disease and disability (directly and indirectly). In a course like SDH211 at Sefako Makgatho Health Sciences University (SMU), the expectation is not only memorisation of definitions, but the ability to interpret health realities using social theory, epidemiology, and a health systems perspective.

Defining Social Determinants of Health and Illness

A strong starting point is to differentiate between determinants and risk factors:

• Risk factors are measurable characteristics associated with health outcomes (e.g., high blood pressure, smoking).
• Determinants of health are upstream drivers that shape exposure to risk factors and shape vulnerability and resilience (e.g., income, education, housing, stigma, employment conditions).

For example, tobacco use is a risk factor for lung disease, but the determinants might include:

• living or working in environments where tobacco is culturally accepted or heavily marketed,
• unemployment leading to stress and coping behaviours,
• low educational attainment reducing health literacy,
• limited access to cessation services due to service distribution.

In SDH211 terms, social determinants are “root causes” that shape patterns of health and illness.

Levels of Influence: Individual, Community, and Structural

Many SDH models operate at multiple levels:

1. Individual-level influences
   • health literacy, knowledge, beliefs
   • personal behaviours
   • perceived control over health
2. Interpersonal/community-level influences
   • social support networks
   • peer norms and community culture
   • local safety and collective efficacy
3. Institutional-level influences
   • how clinics/hospitals treat patients
   • school policies and disciplinary practices
   • workplace protections and labour rights
4. Structural-level influences
   • legislation and policy
   • economic structures and labour markets
   • housing markets and land-use patterns
   • historical legacies (e.g., apartheid spatial planning)

A common exam skill is to identify which level a scenario belongs to. For instance:

• A person misses antenatal appointments because she cannot afford transport → community/institutional + structural link (transport costs reflect structural poverty and spatial inequality; clinic access may reflect institutional planning).
• A clinic routinely closes early due to staffing shortages → institutional/systemic determinant.
• A community has high rates of violence → community determinant shaped by structural factors such as poverty, policing, unemployment, and social cohesion.

The South African Health Inequality Context

South Africa’s health profile cannot be understood solely by clinical epidemiology. Social determinants help explain persistent disparities across:

• income groups (poverty vs economic security),
• urban vs rural areas,
• formal vs informal settlements,
• education levels,
• gender and age.

Key structural features shaping SDOH include:

• unequal access to quality schooling and educational outcomes,
• uneven employment and underemployment,
• housing shortages and overcrowding,
• service delivery challenges (water, sanitation, public transport),
• transport cost burdens and long travel times,
• gender-based violence (GBV) and coercive relationships,
• stigma and discrimination linked to HIV, disability, migration status, and mental illness.

In SDH211, you are expected to use these features to interpret health outcomes. For example, HIV transmission risks, ART adherence, maternal health outcomes, TB exposure, and mental health burden can all be linked to social conditions.

Illness Pathways: How Social Conditions Become Disease

An effective framework for exam answers is to describe pathways, not only determinants. Typical pathways include:

• Material pathway (resources and living conditions):
  Poverty → inadequate nutrition, poor housing, overcrowding → higher susceptibility to infections, chronic diseases, and complications.

• Behavioural pathway (health behaviours shaped by constraints):
  Limited opportunities and stress → harmful coping behaviours (e.g., smoking, alcohol misuse, risky sexual behaviours).

• Psychosocial pathway (stress and social relationships):
  Discrimination, insecurity, and stigma → chronic stress responses → hypertension, depression/anxiety, weakened immunity.

• Health-system pathway (access and quality of care):
  Distance to services, appointment processes, costs, and waiting times → delayed diagnosis and treatment → worse outcomes.

• Structural-policy pathway (laws and social protection):
  Labour regulation, social grants, education policy, urban planning → determine exposure to risk and availability of protective supports.

A strong exam response often includes at least two pathways from the scenario.

Social Determinants and Epidemiology: Evidence and Interpretation

While SDH211 does not require advanced statistical computation, you need to understand how evidence is interpreted. Common patterns:

• Gradient relationships: as income or education increases, risk decreases (not always linearly, but often in a consistent direction).
• Place-based effects: neighbourhoods show independent effects beyond individual factors—due to service access, environment, and social norms.
• Non-medical influences on medical outcomes: adherence to medication can depend on clinic accessibility, transport, social support, and mental health.

A key exam skill: avoid blaming individuals for health outcomes without considering determinants. If a person’s health is poor, social context may determine whether the person can follow advice, access services, and manage stress.

Putting It Together: SDH as a Lens for “Why” Health Differences Exist

In SDH211, your conceptual takeaway should be:

• Determinants are upstream and systemic.
• Pathways connect conditions to disease.
• Social inequalities produce predictable differences in health outcomes.
• Health and illness are not only biological events but also social experiences.

This understanding prepares you for applying SDH concepts to South African health issues such as communicable diseases, maternal and child health, non-communicable diseases (NCDs), disability, and mental health—each of which has strong social determinants.

SDH Frameworks and Analytical Tools Used in SDH211 (with South Africa Applications)

To answer SDH211 exam questions effectively, you need more than definitions—you need frameworks and a method for analysis. Frameworks help you structure arguments: identify determinants, assign levels of influence, describe pathways, and propose interventions that can be assessed for feasibility.

Major SDH Frameworks You Should Recognise

1) The Social Gradient and Health Equity Approach

The social gradient concept suggests that health worsens as social position worsens. In South Africa, this might be visible across income categories, education levels, and employment status. Health inequity is not merely difference; it is avoidable and unjust difference.

Exam application examples:

• Blood pressure control rates show a gradient by income and educational attainment due to differences in health literacy, medication access, and time/transport costs.
• Childhood stunting patterns vary by household wealth, sanitation access, and caregiver education.

2) The “Causes of the Causes” (Upstream Thinking)

This is a method of describing how proximal factors (e.g., smoking) arise from distal drivers (e.g., poverty, marketing, workplace cultures, unemployment). “Causes of the causes” aligns with structural approaches.

Exam application example:

• High TB rates in an overcrowded community are not only about exposure to TB bacteria. They reflect housing insecurity, ventilation conditions, and delayed care—root causes can include unemployment and inadequate housing provision.

3) Commission on the Social Determinants of Health (SDH Conceptual Model)

Many SD courses adopt a conceptual model grouping determinants into:

• structural determinants (political context, socioeconomic position, governance),
• intermediary determinants (material circumstances, psychosocial factors, health behaviours, health systems).

South African exam relevance:
South African health outcomes reflect both intermediary determinants (living conditions, stress, access to care) and structural determinants (history of inequality, policy frameworks, labour markets, and spatial segregation).

Analytical Tools: How to Structure Answers in SDH211

A reliable structure for long-answer questions:

1. Identify the health problem
   • specify illness and population (e.g., adolescent pregnancy, TB, depression, diabetes complications).
2. State the suspected social determinants
   • at least two to four determinants across levels (individual, community, structural).
3. Explain pathways
   • material, psychosocial, behavioural, health-system, structural-policy pathways.
4. Use the South African context
   • refer to service delivery, inequality, transport burdens, stigma, gender norms.
5. Propose interventions
   • primary prevention (upstream), secondary (earlier detection), tertiary (care and rehabilitation).
6. Consider feasibility and unintended consequences
   • who benefits, who is excluded, barriers to implementation.

This method helps you avoid vague statements.

Determinants Mapping: From Scenario to Determinant Categories

When faced with a case study, classify determinants:

• Economic determinants
  • unemployment, household income, food insecurity, informal work
• Educational determinants
  • literacy, school attendance, school quality, youth opportunities
• Housing/environmental determinants
  • overcrowding, water quality, sanitation, indoor air pollution
• Employment/workplace determinants
  • occupational hazards, job security, working conditions, labour rights
• Social and community determinants
  • social cohesion, violence exposure, community safety, peer norms
• Cultural determinants
  • beliefs affecting healthcare-seeking, stigma and discrimination norms
• Political and governance determinants
  • policy enforcement, budget allocation, service coverage, social protection
• Gender and power determinants
  • GBV, unequal caregiving burdens, norms around sexuality and consent
• Health system determinants
  • access, quality, waiting times, availability of medicines, continuity of care

A high-quality exam response often uses a mini-matrix: determinant → pathway → health outcome.

Interrogating Power, Stigma, and Discrimination

A distinct SDH skill is analysing health through power and social meaning. Stigma functions as a determinant by:

• discouraging testing and disclosure,
• limiting social support,
• reducing willingness to seek care,
• increasing psychological distress.

South Africa examples you may be expected to address:

• HIV-related stigma and the fear of being identified in small communities.
• Stigma in mental health where people may be labelled as “weak” or “dangerous.”
• Disability stigma affecting access to schooling and employment.
• Xenophobia affecting healthcare access for migrants and asylum seekers.

An exam answer should connect stigma to specific mechanisms:

1. stigma → delayed care seeking,
2. delayed care → worse disease severity,
3. stigma → mental health burden and stress,
4. stress → worsened chronic disease management.

Case-Based Reasoning: TB, HIV, Maternal Health, and NCDs

To show depth, consider how determinants appear across conditions. Here are structured examples you can adapt:

Example A: TB in a crowded community

• Determinant: overcrowded housing and poor ventilation
• Pathway (material): increased airborne transmission risk
• Pathway (health system): long travel times and clinic waiting → delayed diagnosis
• Outcome: severe TB, higher likelihood of relapse or treatment interruptions

Example B: HIV and ART adherence

• Determinant: transport costs and clinic accessibility
• Pathway (health system): missed appointments due to cost/time
• Determinant: stigma
• Pathway (psychosocial): stress and fear of disclosure → non-adherence
• Outcome: higher viral load, treatment failure risk

Example C: Maternal health and adolescent pregnancy

• Determinant: gender inequality and power dynamics
• Pathway (behavioural/health seeking): limited negotiation power to use contraception
• Determinant: education disruption
• Pathway (structural): fewer opportunities and reduced health literacy
• Outcome: pregnancy complications, reduced early antenatal booking

Example D: Diabetes complications

• Determinant: food insecurity
• Pathway (material/behavioural): difficulty following diet plans
• Determinant: limited access to routine monitoring
• Pathway (health system): delayed detection of complications
• Outcome: progression to kidney disease or vision impairment

Evaluating Interventions: Levels and Logic Models

SDH interventions can be placed into levels:

• Upstream policies: improve employment, education quality, housing, and social protection.
• Community interventions: strengthen social support, violence prevention, community health worker programmes.
• Service delivery reforms: reduce waiting times, improve medication continuity, integrate care.
• Individual supports: health literacy, counselling, behaviour change programmes.

A logic model format (useful for exams):

1. Inputs: funding, staffing, medicines, partnerships
2. Activities: outreach, screening, education, transport support
3. Outputs: number screened, number referred, adherence rates
4. Outcomes: earlier diagnosis, improved control, reduced complications
5. Impact: reduced inequities and improved population health

This encourages you to think beyond “awareness campaigns” and propose measurable change.

Counter-arguments: Avoiding Common Pitfalls

A strong SDH answer also demonstrates critical thinking:

• Pitfall: blaming individuals for risky behaviour
  • Counter: behaviours are shaped by constraints; interventions must address structural barriers.
• Pitfall: assuming education alone solves all problems
  • Counter: even with knowledge, transport costs, stigma, and unemployment may limit action.
• Pitfall: focusing only on healthcare services
  • Counter: health systems are important but determinants like housing and income shape initial risk.

Examiners often reward students who show awareness of complexity and limits of interventions.

Summary of Analytical Competence

By the end of this framework section, you should be able to:

• translate a scenario into determinants,
• explain pathways,
• place determinants in levels (intermediate vs structural),
• connect evidence to reasoning,
• propose interventions with feasibility and equity in mind.

These competencies are central to SDH211 outcomes.

Cluster 1 (SMU): SDH211 Clinical Sociology Applications—From Determinants to Health Care Encounters and Outcomes at Sefako Makgatho Health Sciences University

This section stays anchored to Sefako Makgatho Health Sciences University (SMU) and develops SDH211-focused applications that often appear in assessment questions. In medical sociology and related SDH modules, the “bridge” between social determinants and clinical practice is essential: how determinants shape patients’ experiences of the healthcare system and how service delivery can reinforce or mitigate inequalities.

Interpreting Health Care Access Through a Sociological Lens

Access is not just “can you get to a clinic?” Access includes:

• Availability: whether services exist where people live,
• Affordability: transport costs, time off work, hidden costs,
• Accessibility (acceptability): whether people feel respected, safe, and understood,
• Accommodation: whether services fit real schedules and languages,
• Approachability: whether communities know services exist and how to use them.

In SDH211-style reasoning, access barriers should be described in social terms. For example:

• A patient may have a clinic nearby but cannot attend due to job insecurity or fear of losing wages for the day.
• A patient may avoid a clinic due to past humiliating treatment or judgemental attitudes.
• A patient may not adhere to medication due to family responsibilities or inability to store medication safely in crowded housing.

Patient Journeys: Delays and Drop-offs

A common exam concept is the “pathways to care,” including:

1. Perceived need: when the person recognises illness and decides it matters.
2. Help-seeking: choosing whether, when, and where to seek care.
3. Service entry: reaching and registering for services.
4. Diagnosis and treatment: receiving tests, results, and medication.
5. Continuation: staying in care and following treatment plans.

Social determinants influence each stage:

• Poverty delays perceived need due to competing priorities.
• Stigma delays help-seeking.
• Transport delays service entry.
• System shortages delay diagnosis and treatment.
• Family stress affects continuation and adherence.

Health Care Encounters: Respect, Communication, and Power

In medical settings, inequality can show up in everyday interactions:

• Communication barriers
  • language differences,
  • low literacy leading to misunderstanding instructions,
  • health information delivered in complex terms.
• Respect and stigma
  • patients being treated as “non-compliant,”
  • judgement about substance use, sexual behaviour, mental health, or homelessness.
• Power dynamics
  • clinicians’ authority shaping patient trust,
  • patient fears of poor outcomes if they speak up.

An SDH approach insists that communication and respect are not “soft factors”—they affect diagnosis, adherence, and patient engagement.

Example scenario to practise:
A young woman with hypertension stops her medication because she feels embarrassed when nurses scold her for missed appointments.
SDH framing:

• determinant: perceived stigma and judgement at the institutional level,
• psychosocial pathway: reduced trust and stress,
• health system pathway: reduced continuity of care,
• outcome: uncontrolled BP and increased complication risk.

Social Determinants and Chronic Illness Management

Chronic diseases demand ongoing behaviour changes and continuity of care. SDH influences this strongly.

Adherence in contexts of poverty

Patients may face:

• food insecurity affecting diet recommendations,
• inability to buy glucometer strips or attend monthly reviews,
• difficulty maintaining routines in crowded homes.

In exams, avoid stating “patients don’t comply.” Instead:

• identify constraints,
• explain how system design and social environment shape adherence.

Disability and functional limitations

Disability influences determinants:

• transport and physical access to clinics,
• stigma in workplaces leading to unemployment and poverty,
• barriers in schooling affecting health literacy.

A strong answer connects disability to both material and institutional determinants.

Gender, Sexuality, and Structural Violence in Health Care

Gender-based inequity is central in South African health outcomes. Structural violence can appear as:

• limited autonomy in reproductive health choices,
• GBV exposure leading to trauma and mental health burden,
• fear of partner violence limiting healthcare attendance.

SDH211 often expects you to connect:

• GBV determinants → antenatal care patterns → outcomes,
• trauma exposure → substance use and mental health → health service use.

Mini-case reasoning:
A survivor of intimate partner violence presents late for antenatal care.
SDH determinants:

• fear and constrained autonomy,
• potential partner monitoring,
• limited support networks,
• risk of stigma if disclosed.
  Pathways:
• psychosocial stress,
• delayed health system entry,
• worse pregnancy outcomes.
  Intervention considerations:
• confidential screening,
• referral pathways,
• community support integration.

Social Protection and Health

South Africa has social protection mechanisms such as social grants, which can indirectly improve health outcomes by:

• improving household food security,
• supporting transport to clinics,
• reducing household stress.

In SDH211 analysis, quantify the effect carefully when asked, but even without numbers you should explain mechanism:

• grants reduce financial shocks,
• improved stability supports adherence and follow-up.

Workforce, Clinics, and System Strain as Determinants

SDH is not only about patients; it includes institutional capability.

System-level determinants:

• staffing shortages,
• medicine stock-outs,
• long waiting times,
• fragmented care between services.

These factors influence outcomes:

• delayed treatment for TB/HIV leads to progression,
• missed chronic medication renewals leads to complications.

In a sociological framing, health system strain can create a “disciplinary” environment where patients are rushed, leading to misunderstandings and reduced trust.

Example Essay-Style Answer: Linking Determinants to Outcomes

Below is a model of how to structure a response (use similar structure in exams):

Health problem: high rates of missed ART appointments in a township clinic.
Determinants:

• economic insecurity and transport costs,
• clinic waiting times and long queues,
• HIV stigma in the community,
• incomplete integration of psychosocial counselling.
  Pathways:
• health-system pathway: transport + time cost → missed appointments,
• psychosocial pathway: stigma → concealment and stress → non-attendance,
• behavioural pathway: fear of disclosure at the clinic → reduced engagement.
  Outcomes: increased viral load and increased risk of transmission and opportunistic infections.
  Interventions:

1. reduce waiting times through appointment scheduling,
2. provide transport support or community pick-up points where feasible,
3. strengthen community-based adherence support,
4. integrate mental health and counselling services,
5. train staff for stigma reduction and respectful communication.

This demonstrates SDH211’s core expectation: determinants → pathways → outcomes → interventions.

Practising “Explain” and “Discuss” Questions

Common verbs in exams:

• Explain: show mechanism and logic.
• Discuss: present arguments and consider complexity (including counterpoints).
• Evaluate: discuss strengths/limitations and feasibility.
• Compare: differentiate between determinant categories or levels.

Counter-argument practice:
If an intervention focuses only on counselling, argue that counselling may be insufficient without addressing transport costs, stigma, and appointment design. Include both sides.

Summary: SMU SDH211 Application Competence

By linking social determinants to clinical encounters and service use, students can produce answers that reflect:

• sociological understanding of health behaviour,
• health system determinants,
• equity and access,
• practical interventions.

This competence is often what distinguishes top-performing SDH211 responses from purely descriptive answers.

Cluster 2 (SMU): Applying Social Determinants to South African Case Studies—TB, HIV, Maternal Health, NCDs, and Mental Health in a Determinants-to-Action Framework

This section uses an exam-ready approach: take major health areas and demonstrate how SDOH explains patterns, then translate that into intervention ideas. The goal is to build “reusable reasoning” for multiple questions: identify determinants, describe pathways, and propose action at appropriate levels.

Case Study Approach: How to Write Detailed Answers

Use this case-study scaffold:

1. Context description: location type (urban township, rural area, informal settlement) and population group.
2. Health outcome: what condition and what pattern (late presentation, poor control, high incidence).
3. Determinants list: at least three determinants across categories.
4. Pathway explanation: how each determinant contributes to disease risk or care delay.
5. Intervention plan: upstream, service, and community components.
6. Equity lens: who benefits; who may still be left out and why.
7. Implementation considerations: barriers and how to overcome them.

This scaffold can be applied repeatedly.

TB and Social Determinants: Crowding, Airflow, and Service Navigation

Key determinants

• Housing quality and overcrowding
  • increased exposure due to shared indoor spaces
  • limited ventilation
• Nutrition and food insecurity
  • weakened immunity and ability to complete treatment
• Income and unemployment
  • inability to take time off for clinic visits and to prioritise care
• Stigma
  • fear of being identified with TB
• Health system navigation
  • delays in diagnosis due to access issues and waiting times

Mechanisms to discuss

• Material pathway: crowded living increases exposure.
• Health-system pathway: delays in diagnosis mean patients remain infectious longer.
• Behavioural pathway: symptom recognition and help-seeking shaped by knowledge and previous experiences with clinics.

Intervention ideas (determinants-to-action)

• Improve case finding through community health worker outreach.
• Strengthen infection control in facilities.
• Support adherence with food support or transport assistance where feasible.
• Address housing and ventilation as long-term determinants.
• Reduce stigma through community education delivered by trusted local channels.

Counterpoint: infection control alone is insufficient if people return to overcrowded homes where exposure persists. A robust answer includes both facility and community determinants.

HIV and Social Determinants: Stigma, Mobility, and Treatment Continuity

Key determinants

• Stigma and discrimination
  • fear of disclosure to partners, family, and neighbours
• Gender power dynamics
  • inability to negotiate condom use
• Economic vulnerability
  • costs of travel to ART clinics and inability to maintain routines
• Mobility and migration
  • interruptions in care across changing residences
• Mental health and trauma
  • coping challenges affecting adherence

Mechanisms to discuss

• Psychosocial pathway: chronic stress and fear reduce willingness to engage.
• Health system pathway: interruptions lead to viral rebound.
• Structural-policy pathway: social protection and clinic accessibility determine continuity.

Intervention ideas

• Community adherence support groups that protect confidentiality.
• Youth-friendly services and counselling that respects autonomy.
• Differentiated service delivery (where appropriate) to reduce visit burden.
• Link ART programmes with social supports (e.g., transport or food assistance).
• Strengthen referral pathways for trauma counselling and GBV services.

Exam sophistication: mention how confidentiality protects engagement in tight-knit communities.

Maternal Health and Adolescent Pregnancy: Education, Gender Norms, and Safety

Key determinants

• Education
  • school dropout reduces knowledge and protective opportunities
• Gender inequality
  • limited agency to make reproductive decisions
• GBV
  • coerced sex and trauma influence maternal outcomes
• Transport and service accessibility
  • inability to reach ANC services early
• Respectful maternity care
  • fear of mistreatment discourages attendance

Mechanisms to discuss

• Behavioural pathway: contraception use affected by norms and fear.
• Health system pathway: delayed ANC leads to missed opportunities for screening and prevention.
• Psychosocial pathway: stress and trauma increase adverse outcomes.

Intervention ideas

• Integrate respectful care training and accountability mechanisms in maternity services.
• Expand youth and adolescent reproductive health education in schools and clinics.
• Provide confidential counselling and GBV referral pathways.
• Support transport costs and reduce long waiting times for ANC visits.
• Strengthen community outreach to identify pregnancies early.

Counterpoint: awareness campaigns alone may fail if gender-based coercion persists. Intervention must address power relations.

Non-Communicable Diseases (NCDs): Food Environments, Stress, and Care Fragmentation

South Africa experiences a “double burden”: communicable diseases and rising NCDs. NCD risk is not only individual choice; social environment matters.

Key determinants

• Food insecurity
  • reliance on cheap, energy-dense foods
• Urban design and physical activity
  • limited safe spaces, high-risk environments
• Chronic stress
  • poverty, violence exposure, and job insecurity influence metabolic health
• Access to screening
  • fewer routine check-ups lead to late diagnosis
• Medication continuity
  • stock-outs and appointment scheduling impact control

Mechanisms to discuss

• Material pathway: nutrition and living conditions shape risk.
• Psychosocial pathway: stress contributes to hypertension and poor glycaemic control.
• Health-system pathway: delayed screening and inconsistent medicine supply worsen outcomes.

Intervention ideas

• Community-based screening with clear referral pathways.
• Strengthen chronic medication supply chains.
• Provide culturally appropriate health education that acknowledges food realities.
• Integrate mental health supports where stress and depression affect chronic disease management.

Exam nuance: recognise that recommending diets without considering affordability can be inequitable.

Mental Health: Social Exclusion, Violence Exposure, and Stigma

Mental health is strongly shaped by social conditions.

Key determinants

• Violence and trauma
  • GBV and community violence
• Stigma
  • discourages care seeking and disclosure
• Economic instability
  • unemployment contributes to depression and anxiety
• Social support
  • networks can protect; isolation increases risk
• Health service capacity
  • shortages in mental health professionals and long referral processes

Mechanisms to discuss

• Psychosocial pathway: trauma and stress affect mood regulation.
• Behavioural pathway: substance use and coping behaviours.
• Health-system pathway: delayed access due to stigma and service limitations.

Intervention ideas

• Community education to reduce stigma.
• Integrate mental health screening into primary care.
• Train primary care staff for basic psychosocial interventions.
• Strengthen referral networks and follow-up.

Counterpoint: if services are unavailable or inaccessible, screening alone may not improve outcomes. Emphasise availability and continuity.

Comparative Analysis: Patterns Across Conditions

A high-scoring exam response may compare:

• TB/HIV: stigma and treatment continuity are central; housing and service access matter.
• Maternal health: gender inequality, safety, and respectful care drive timing of ANC and outcomes.
• NCDs: food environments, stress, and medication continuity shape long-term control.
• Mental health: stigma and violence exposure influence both risk and care seeking.

This comparison demonstrates that SDH211’s “determinant logic” works across multiple conditions.

Summary of Case Study Competence

You should now be able to:

• apply SDOH categories to major South African health challenges,
• explain pathways and mechanisms,
• propose integrated interventions with equity and feasibility in mind.

This builds the foundation for more advanced critical discussion and evaluation questions.

Cluster 3 (SMU): SDH211 Policy, Prevention, Ethics, and Exam-Ready Evaluation of Interventions in the South African Health System

This section focuses on how SDH211 connects determinants to policy and ethical practice—how to evaluate interventions, consider trade-offs, and argue for equity in health outcomes. It also provides concrete guidance for exam performance: what markers look for, how to avoid common errors, and how to write structured “evaluate” answers.

Prevention in SDH: Upstream vs Downstream Strategies

Prevention is often discussed in three tiers:

• Primary prevention: prevent disease before it begins by addressing root causes (e.g., improving housing, reducing poverty, ensuring safe water).
• Secondary prevention: early detection and timely intervention (e.g., screening programmes for TB, hypertension).
• Tertiary prevention: reduce complications and disability through treatment and rehabilitation (e.g., ongoing management of chronic disease).

In SDH211, you should connect prevention type to social determinants:

• Primary prevention requires structural change.
• Secondary requires accessible screening and trust.
• Tertiary requires continuity and community support.

Evaluating Public Health and Health System Interventions

When asked to evaluate an intervention, include:

1. Effectiveness: Does it reduce risk or improve outcomes?
2. Equity: Who benefits most? Does it narrow or widen disparities?
3. Feasibility: Can it be implemented given local resources and systems?
4. Sustainability: Is it maintained beyond pilot funding?
5. Acceptability: Will communities engage? Are there cultural concerns?
6. Unintended consequences: Could it stigmatise, exclude, or burden patients?

A strong exam answer uses the equity lens: even “successful” programmes may reinforce inequality if they primarily reach those with better access.

Common Intervention Examples and How to Critically Analyse Them

Example 1: Health education campaigns

Strengths:

• improve knowledge,
• can reduce stigma,
• can motivate testing and care seeking.

Limitations in SDH terms:

• knowledge without resources may not change behaviour (e.g., cannot attend due to transport costs),
• if delivered in ways that ignore literacy and language, it may not be effective,
• if stigma persists, campaigns may not overcome fear.

Better approach: combine education with system changes (transport support, community health worker outreach).

Example 2: Screening programmes (TB, hypertension, diabetes)

Strengths:

• earlier detection,
• can reduce disease burden.

Limitations:

• screening without referral and medication availability can create frustration and drop-out,
• people with least access may miss screenings due to scheduling barriers,
• stigma can deter participation.

Better approach: ensure integrated care pathways and follow-up systems.

Example 3: Appointment scheduling improvements

Strengths:

• reduces waiting times,
• improves adherence.

Limitations:

• if transport remains costly, reduced waiting times may not solve access,
• if labour conditions prevent time off work, scheduling alone is insufficient.

Better approach: pair scheduling reforms with community-based support.

Example 4: Support groups and adherence counselling

Strengths:

• social support,
• psychosocial protection,
• helps navigate stigma.

Limitations:

• confidentiality concerns might reduce participation,
• if group sessions are not accessible (timing, language), attendance may be low.

Better approach: confidential and flexible delivery.

Ethics and Social Determinants: Justice, Respect, and Non-Maleficence

SDH211 often intersects with ethics because social determinants raise questions of fairness:

• Should patients be blamed for outcomes shaped by poverty?
• How should services prioritise high-need communities?
• How to balance individual autonomy with population equity goals?

Key ethical principles in SDH context:

• Equity: resources should favour those with greatest need, not only those who are easiest to reach.
• Respect for persons: ensure informed decision-making in culturally and linguistically appropriate ways.
• Non-maleficence: avoid policies that might unintentionally stigmatise groups.
• Beneficence: design interventions that genuinely benefit target populations.

Governance, Policy, and the Role of the State

Structural determinants link to governance:

• regulation of housing markets,
• enforcement of labour protections,
• social protection policies,
• public investment in health infrastructure.

In South Africa, the state plays an important role in:

• financing public health,
• setting service standards,
• supporting primary healthcare,
• coordinating disease control programmes.

An exam answer should connect policy to lived realities:

• if transport infrastructure is weak, clinic attendance will remain low regardless of clinical quality.
• if social grants are insufficient or delayed, household food security and ability to attend services decline.

Designing a Determinants-Informed Intervention: A Step-by-Step Logic

A practical method for exam questions requiring intervention design:

1. Select a target population and health outcome
   • e.g., adult men with poor hypertension control in a township clinic catchment area.
2. Identify priority determinants
   • list 3–5 determinants that most directly drive the outcome.
3. Match interventions to determinants
   • for each determinant, propose action at a matching level.
4. Define measurable outputs
   • number screened, follow-up rates, appointment attendance.
5. Define expected outcomes
   • BP control rates, reduced complications.
6. Plan implementation
   • roles of clinic staff, community health workers, NGOs, and government structures.
7. Plan monitoring and evaluation
   • define indicators and feedback loops.

This step-by-step structure shows exam readiness and prevents vague suggestions.

Example “Evaluate” Question and Model Answer Outline

Prompt (typical style): “Evaluate the role of social determinants in explaining delayed TB diagnosis and propose interventions.”

A model evaluation outline:

1. Explain the role of social determinants
   • poverty affects symptom recognition and help-seeking,
   • overcrowding increases exposure, raising symptom burden,
   • stigma reduces clinic attendance,
   • transport and waiting times delay diagnosis.
2. Assess existing health system response
   • discuss strengths like access to primary healthcare,
   • mention limitations like stock-outs or referral delays.
3. Propose multi-level interventions
   • community case finding through health workers,
   • reduce stigma through community engagement,
   • improve service access (transport support, shorter waiting times),
   • ensure rapid diagnosis and treatment availability.
4. Consider equity and implementation
   • focus on informal settlements and rural areas if relevant,
   • ensure confidentiality to protect people from stigma.

This model demonstrates evaluation rather than description.

Counter-Arguments and Limits: Avoid Overpromising

Critical answers should mention limitations:

• Structural changes take time (housing reform, income support).
• Healthcare system reforms require budgets and management capacity.
• Community interventions depend on sustained community trust.
• Data limitations can hinder targeting.

However, SDH does not mean “nothing can be done now.” It means interventions must be sequenced:

• quick wins in service delivery and stigma reduction,
• longer-term structural reforms.

Measuring Success: Indicators That Reflect SDH

Not all outcomes are health outcomes alone. Indicators can reflect determinants:

• Service access indicators
  • average waiting time,
  • proportion attending within recommended time frames.
• Adherence indicators
  • appointment follow-up rates,
  • medication refill rates.
• Equity indicators
  • differences in outcomes across income, location (urban/rural), and education.
• Social indicators
  • reduction in food insecurity rates,
  • improvement in housing conditions (where measured),
  • reductions in stigma reported in community surveys.

An exam marker often rewards those who propose indicators that match determinants.

Conclusion-Like Integration: What SDH211 Ultimately Tests

SDH211 assessments typically test:

• your conceptual clarity about determinants and pathways,
• your ability to apply frameworks to South African health realities,
• your ability to design and evaluate interventions with an equity lens,
• your skill in writing structured, evidence-informed answers.

A high score comes from being specific: not just “poverty affects health,” but how it affects care-seeking, adherence, stress, exposure, and service navigation, and what interventions address those specific mechanisms.

Final Summary of Study Strategy for SDH211

To prepare effectively:

• Practise converting scenarios into determinants and pathways.
• Practise writing short “evaluate” structures (strengths, limitations, equity, feasibility, unintended consequences).
• Practise TB/HIV/maternal/NCD/mental health cases using the same scaffold.
• Practise linking intervention type (upstream/secondary/tertiary) to determinants.

This produces exam-ready competence: coherent reasoning, South Africa–relevant examples, and structured arguments aligned with SDH211 expectations within the SMU medical sociology context.
