KEY CONCEPTs

unnamed
Health Equity
The absence of unfair, avoidable and remediable differences in health among population groups defined socially, economically, geographically, or demographically.





unnamed
Health Inequity
Differences in health status or in the distribution of health resources between different population groups, arising from the social conditions in which people are born, grow, live, age and die.



unnamed
Distributive Justice
The principle of distributive justice requires that health services are accessible to individuals according to need and within the context of resource availability.





unnamed
Intersectionality
A framework introduced by Kimberlé Crenshaw to explain how interlocking systems of power combine simultaneously to produce distinct forms of advantage and disadvantage that shape a person’s social location and social power and, through that social identity, their exposure to risk, access to care, and health outcomes.

UNRAVELING COMPLEXITY IN HEALTH

Advances in Modern Medicine and Health
Picture1

Medicine has made great strides in the last 100 years - from saving of lives in acute life-threatening emergencies, to thoroughly improving health outcomes through preventive and curative interventions and minimizing the deterioration in the quality of life related to chronic disease.  The advancement and integration of technology including complex, computerized machines, has played a monumental role in the study of the human body and its functioning, diagnosis, and treatment of disease.

Disease and Social Context

Yet, today, besides emerging diseases we are witnessing the re-emergence of diseases that had declined dramatically but are again becoming a problem for a significant proportion of the world’s population. Tuberculosis and malaria are examples. Tuberculosis (TB) is preventable and curable. Yet, it is not without reason that TB is called a disease of poverty as it disproportionately affects the poor.  While more than 95 per cent of TB deaths occur in low-and-middle income countries (LMICs), TB also affects the most poor and vulnerable populations such as the homeless, urban poor, HIV-infected persons, drug users, and immigrants in developed countries.

Poverty and disease are mutually reinforcing.  Epidemics and chronic disease cluster, recur, and prevail amidst rampant poverty. 

           Beyond Medicine
This is because the transmission of pathogens and adaptation of pathogens are facilitated by a host of factors, some beyond medicine. Examples are environmental and ecological changes; changing human-animal ecosystems; economic development; deforestation; war and conflict; urbanization; bioterrorism; trade and travel; drug resistance; poor access to health care; fragile health systems; weak surveillance; limited laboratory diagnostic capacity; and availability of public health infrastructure among others

Social Justice and Health

Even when biological risk is equal, those living in deprivation are at greater risk of disease. It is this unfair and avoidable disadvantage experienced by socially disadvantaged populations that contributes to negative health outcomes which is called health inequity. Health inequity is also significantly associated with healthcare inequities.

 

The concept of health/healthcare inequity or health equity, therefore, embodies the notion of social justice because it is anchored within principles of fairness and distributive justice.

 

In this unit, we will explore evidence-based approaches to understand the importance of social justice and human rights in health, paying considerable attention to health systems as an important determinant of health equity.

 


UNRAVELLING HEALTH AND ITS COMPLEXITY


The Biomedical and Social Models of Health

Having outlined health as multidimensional, interrelated, and dynamic, we now turn to the two lenses that organise how illness and care are explained in practice. The biomedical model looks inward, at cells, organs, and pathogens. It treats disease as a breakdown in biological function and focuses on diagnosis and cure. The social model of medicine looks outward, at how living and working conditions, social position, and policy environments influence who becomes ill and who gets care.

Video 2 introduces the biomedical model and the social model of health, sketches how each developed, and clarifies their scope and limits.

The aim is to see when each lens is sufficient, when it falls short, and how they can be used together in complementarity in clinical work and public health.

STRUCTURAL DISCRIMINATION
We have distinguished health from medicine and traced how the biomedical and social models developed. Knowing that social conditions influence health is only the beginning. To understand why health outcomes remain unequal, we must look at how social structures themselves distribute advantage and disadvantage. Patterns of discrimination are not random. They are embedded in institutions, laws, norms, and everyday interactions. The concept of structural discrimination helps us see how these patterns sustain inequity over time.
We will now review the Malaysian data on life expectancy, morbidity, and mortality.

Explore and analyze life expectancy trends in Malaysia using the Open DOSM Life Expectancy Dashboard and Statistics on Causes of Death, Malaysia to examine the most recent year available. Describe what the figures show without making causal claims.

First, identify the highest and lowest life expectancy values and state the absolute gap in years. Next, note the leading causes of death overall (and by sex or age where reported). Try to explain how these descriptive patterns might reflect differences in living conditions, service availability, or protection from risk, and state one policy that could plausibly narrow the observed gap.
For another powerful example, take a look at the data on HIV released by UNAIDS in 2020. What can we learn about structural factors and structural discrimination from the global data on HIV? Think about how structural factors influence the rise in the number of new HIV infections causing them to even surpass target numbers.

1. Click every hotspot on the HIV image.
2. Read the explanation in each pop-up carefully.
3. Look for a pattern across the hotspots.


Intersectionality

We have just seen that structural discrimination manifests in population patterns such as differences in life expectancy and other health outcomes. But population patterns do not tell us how inequality is experienced by individuals seeking care.

In the next activity you will work through a maternity-care scenario involving two women, Amni and Fatima, who arrive at the same hospital to deliver their babies. They share the same clinical need, but their experiences can differ because their social circumstances differ.


As you work through the activity, focus on three ideas: social identity (how a person is socially recognized), social location (where that places them within social structures), and social power (what that position enables or constrains).



EQUALITY vs EQUITY

So that brings us to the final part of this topic, and to an important question. Answer the question, and check out the slide on  the difference between equality and equity and the summary of Health and Medicine.
