Difficulty: Intermediate | Prerequisites: Lectures 12 and 13 on chronic disease; basic familiarity with socioeconomic status (SES) and its relationship to health outcomes.
This lecture shifts from individual disease to the structural and cultural factors that shape health outcomes. It covers the health gradient (the link between wealth and health), the Black Report's explanations for health inequalities, ecological models, social justice, stigma, social capital and cultural influences on health beliefs. This is the lecture where the course zooms out from biology and behaviour to consider why some populations are systematically sicker than others.
Health outcomes follow a gradient tied to socioeconomic position: each step down in wealth corresponds to worse health. The Black Report offered four explanations for this. The ecological model frames health across micro, meso, exo and macro levels. Social justice principles (Rawls) argue that avoidable health inequalities are inequities. Culture, including Western, Eastern and African health belief systems, shapes how people understand illness, and culturally competent care is essential for reducing disparities.
Health gradient (death gradient)
The pattern in which people one step down from those who are wealthier have worse health and higher mortality. In simple terms, health improves with each rung up the socioeconomic ladder, not just at the poverty line.
Black Report
A landmark report by Sir Douglas Black documenting the link between socioeconomic position and health outcomes, holding across gender and other demographics. The Whitehall studies by Marmot further explored SES hierarchies and health.
Ecological model of health
A framework that organises health determinants across four levels: microsystems (families, schools, neighbourhoods), mesosystems (peer groups), exosystems (parental support, workplaces) and macrosystems (political philosophy, policy).
Social justice (in health)
The acknowledgement that health inequalities can be considered inequities when they are avoidable, unnecessary and unfair. Based on the principles of John Rawls.
Stigma
Unfavourable reactions toward people who are perceived to possess denigrated attributes. Stigma power involves exploitation, control and exclusion, and is most effective when hidden.
Social capital
Civic engagement, interpersonal trust and norms of reciprocity within a community. Bridging social capital links diverse groups and provides access to external resources. Bonding social capital strengthens ties within a community.
Etics
The universal components of ideas across cultures (e.g., the concept of health itself).
Emics
Components of ideas that are particular to certain cultures (e.g., specific beliefs about how to achieve health).
Enculturation
The early-life acquisition of one's own culture.
Acculturation
The process of acquiring a new culture, typically through migration or sustained contact.
People one step down from those who are wealthier have worse health and higher mortality. This is called the death gradient, and it operates as a continuum, not a threshold.
Sir Douglas Black's report noted the persistent link between socioeconomic position and health. The Whitehall studies (Marmot) examined SES hierarchies and health among British civil servants.
Four scientific explanations from the Black Report:
Artefact: The relationship between social position and health is an artefact of the measurement method
Natural and social selection: The social gradient in health results from unhealthy people falling downwards while healthy people rise up
Materialist/structuralist: Economic and sociostructural factors are the primary drivers
Cultural/behavioural differences: Health can partly be explained by individual behaviour, including reckless or problematic lifestyles
Two further explanations:
Psychosocial: Focus on individual (micro) and social (macro) factors. Relative deprivation and lack of perceived control contribute to poor health, coupled with the social effects of income inequality
Neo-material: Focus on inequality and lack of resources overall. Critiques the psychosocial approach for neglecting the broader political context
Microsystems: Families, schools, neighbourhoods
Mesosystems: Peer groups
Exosystems: Parental support systems, parental workplaces
Macrosystems: Political philosophy
Example, low SES across the model:
Microsystem: low birth weight, family instability, poor diet, overcrowding, poor schools
Mesosystem: bullying, gangs, violence, substance use, unprotected sex
Exosystem: low personal control, less social support, unemployment, high stress
Macrosystem: poverty, poor housing, environmental pollution, poor access to health services
Health inequalities are considered inequities when they are avoidable, unnecessary and unfair. John Rawls' principles of a just society call for equal basic utilities, robust equal opportunity and limiting inequalities to those that benefit the least advantaged.
Stigma involves unfavourable reactions toward people perceived to possess denigrated attributes. Stigma power operates through exploitation, control and exclusion, and is most effective when hidden.
Strengthening individuals
Strengthening communities
Improving access to essential facilities and services
Encouraging macroeconomic and cultural change
Social capital encompasses civic engagement, interpersonal trust and norms of reciprocity. Bridging social capital links diverse groups and provides access to external resources. Bonding social capital strengthens ties within a community and can increase odds of good health by 27%. Reciprocity (39%) and trust (32%) also play a role.
Culture encompasses psychological attribute groups, including customs, habits, beliefs, values that shape emotions, behaviour and life patterns. It may include language, modes of thinking and fundamental views of reality. Culture is due to more than genetics.
Cross-cultural research reveals both universals and specificities, though specificity is emphasised. Most research is based on Western, educated, industrialised, rich and democratic (WEIRD) countries, which limits generalisability.
Etics: Universal components of ideas across cultures (e.g., the concept of health)
Emics: Components particular to certain cultures (e.g., which behaviours are stigmatised, how to achieve health)
Christian ideas:
Ascetic tradition: scorned concern for the body, promoted fasting and physical suffering to increase spirituality
Protestant Reformation emphasised purity and health
The Enlightenment brought positivism and individualism
Taoism: The universe is vast and indivisible. Health is about balancing yin and yang. Acupuncture and herbal remedies help restore this harmony
Confucianism: Human suffering is the result of destiny (ming). People strive to accept what fate controls
Buddhism: Heavenly retribution is expected for wrongdoing. Emphasis on reciprocity, retribution and views on attachment
Ayurvedic Medicine: A holistic system from the Indian subcontinent
Herbal and physical remedies are intertwined with various religious belief systems. Spiritual influences and communal orientations are crucial. Illness is commonly attributed to the work of ancestors or supernatural forces, and spiritual healers play important roles. The communal orientation means family and community members are concerned about the negative role of supernatural forces.
Racism contributes to poor mental and physical health among migrants, ethnic minority groups and indigenous people. Perceived discrimination is related to poorer health outcomes including CHD, high blood pressure, obesity, diabetes and poorer mental health.
One-size-fits-all interventions are out of place in healthcare settings, and stereotypes act as barriers. Building culturally competent healthcare systems that enhance health literacy across different racial, ethnic and cultural groups is essential.
Students sometimes think the health gradient only operates at the poverty line. It does not. Each step up the socioeconomic ladder is associated with better health, even among those who are already well-off.
Students may confuse the Black Report's four explanations, treating them as interchangeable. Each proposes a distinct mechanism (measurement artefact, social selection, structural factors, individual behaviour).
Students often assume cultural health beliefs are peripheral to clinical outcomes. They are central. A patient's cultural framework shapes how they understand illness, whether they seek treatment and how they adhere to it.

Etics; emics
Q: What are the four levels of the ecological model of health? Give one example of each for low-SES populations.
A: Microsystem (e.g., family instability, poor nutrition), mesosystem (e.g., bullying, substance use among peers), exosystem (e.g., unemployment, low personal control), macrosystem (e.g., poverty, poor access to health services).
Q: What is the difference between bridging and bonding social capital?
A: Bridging social capital links with diverse groups and provides access to power and resources outside one's community. Bonding social capital consists of inward-looking ties that strengthen bonds within a community.
Q: What is the health gradient?
A: The pattern in which each step down in socioeconomic position corresponds to worse health and higher mortality. It operates across the entire spectrum, not just at the poverty line.
Q: How does the psychosocial explanation for health inequality differ from the neo-material explanation?
A: The psychosocial explanation focuses on individual and social factors such as relative deprivation and perceived control. The neo-material explanation focuses on inequality and lack of resources overall, and critiques the psychosocial approach for neglecting the broader political context.
The health gradient and social justice material connects directly to the health disparities discussion in Lecture 15. The role of stress in socioeconomic health differences ties back to the stress-disease pathways covered in Lectures 12 and 13. Cultural health beliefs are relevant to understanding adherence and intervention design for conditions like HIV, diabetes and hypertension.
