Compare & contrast medical model & social model of health & well-being

1.2 Compare and contrast the medical model and social model of health and well-being

Two main approaches to health, illness, and well-being are the medical model and the social model. The medical model is based on biological factors and professional care, whereas the social model examines environmental and social influences that determine holistic health. This comparison will look at the definitions of each model, features, strengths, limitations, and practical application.

Defining the Medical Model  

The medical model views the body as a machine that may fail. Health is regarded as the lack of illness. Physicians make diagnoses through tests, including scans or blood tests, and then prescribe medications, surgery, or therapy to treat symptoms or underlying issues. As an illustration, insulin is used to treat diabetes, and antidepressants are used to treat depression.

Social Model of Health Advantages and Disadvantages

The Social Model of Health explains that health outcomes are shaped by social, economic, and environmental conditions such as housing, education, income, and working environments. Its advantages include focusing on prevention, reducing health inequalities, and addressing root causes of illness. However, disadvantages include high implementation costs, slow measurable outcomes, and complex policy coordination.

What Is the Social Model of Health?

The Social Model of Health is a public health framework that explains how health is strongly influenced by the social, economic, and environmental conditions in which people live, work, and age. Rather than focusing only on medical treatment, this model emphasises preventing disease by improving the social determinants of health.

Definition

The Social Model of Health states that health outcomes are largely shaped by social determinants, including:

1. income and socioeconomic status

2. education and health literacy

3. employment conditions

4. housing quality

5. access to nutritious food

6. environmental safety

7. social and community networks

These determinants influence people’s ability to maintain good health and avoid disease.

The Dahlgren–Whitehead Rainbow Model

One of the most influential frameworks supporting the social model is the Dahlgren–Whitehead Rainbow Model (1991). This model illustrates how different layers of society influence health.

The layers include:

1. Individual factors – age, sex, genetics

2. Lifestyle factors – diet, physical activity, smoking

3. Social and community networks

4. Living and working conditions – housing, employment, and healthcare access

5. General socioeconomic, cultural, and environmental conditions

The rainbow model demonstrates that health is shaped by multiple interacting layers, not just medical care.

The Social Gradient in Health

Modern public health research shows a consistent social gradient in health, meaning:

People with higher socioeconomic status generally experience better health outcomes and longer life expectancy.

For example, studies across Europe and North America show that individuals in the highest income groups may live 7–10 years longer than those in the lowest groups.

Recognising this gradient helps governments design policies that reduce inequalities in health.

Social Model vs Biomedical Model

The biomedical model vs social model comparison highlights two different approaches to health.

Feature	Biomedical Model	Social Model of Health
Focus	Disease treatment	Social determinants
Level of intervention	Individual patient	Population level
Primary strategy	Diagnosis, drugs, surgery	Prevention, policy change
Time to results	Short-term	Long-term
Scalability	Individual clinical care	Societal and environmental change

The biomedical model focuses on treating illness, while the social model focuses on preventing illness by improving living conditions.

Both models are important for modern healthcare systems.

Advantages of the Social Model of Health

Understanding the Social Model of Health Advantages and Disadvantages requires examining its significant strengths in public health policy.

1. Focus on Prevention

The social model prioritises preventing disease before it occurs.

Preventive strategies include:

1. anti-smoking campaigns

2. healthy school meal programs

3. urban planning that promotes walking and cycling

According to the World Health Organization (WHO), prevention strategies targeting social determinants could reduce the global burden of chronic disease by up to 30–40%.

2. Addresses Root Causes of Disease

Many illnesses are linked to social and environmental conditions rather than purely biological causes.

Examples include:

1. Poor housing leading to respiratory diseases

2. Unsafe workplaces cause injuries

3. Limited food access is increasing obesity and malnutrition

By addressing these root causes, governments can reduce disease rates across entire populations.

3. Reduces Health Inequalities

Health inequalities often mirror economic and social inequalities.

For example:

1. Lower-income populations experience higher rates of heart disease and diabetes.

2. Communities with poor housing conditions experience higher rates of respiratory illness.

Public policies aimed at improving housing, education, and employment opportunities can significantly reduce these disparities.

4. Holistic Perspective on Health

Unlike purely medical models, the social model views health as a multidimensional concept involving:

1. physical wellbeing

2. mental health

3. social wellbeing

For example:

1. Strong social support networks improve mental health outcomes.

2. Access to parks and green spaces lowers stress and increases physical activity.

This holistic approach aligns with the WHO definition of health, which emphasises overall wellbeing.

5. Encourages Cross-Sector Collaboration

Health outcomes are influenced by policies outside the healthcare sector.

The social model encourages cooperation between:

1. health departments

2. education systems

3. housing authorities

4. transportation planners

5. labor regulators

This approach is sometimes called “Health in All Policies”, a strategy promoted by the WHO and many national governments.

6. Improves Long-Term Population Health

Investments in social determinants often produce long-term improvements in public health.

Examples include:

1. Improved sanitation systems, reducing infectious diseases

2. Better education increases health literacy

3. workplace safety regulations reducing injuries

These changes create sustainable health improvements across generations.

Case Study: Finland’s Housing First Policy

One of the most frequently cited examples of the social model of health is Finland’s Housing First programme.

The policy provides permanent housing to homeless individuals before addressing other social issues.

Results:

1. Finland has reduced homelessness by over 40% since 2008.

2. Healthcare and emergency service costs decreased significantly.

3. Research estimates savings of €9,600 per person per year in reduced social service costs.

This case demonstrates how housing policy can directly improve health outcomes.

Disadvantages of the Social Model of Health

Despite its benefits, the social model also has limitations.

1. Difficult to Implement

Improving social determinants requires large-scale policy reforms, such as:

1. national housing strategies

2. education reforms

3. poverty reduction programs

These initiatives require coordination across many government departments.

2. High Economic Cost

Addressing social determinants often involves significant upfront investment.

Examples include:

1. affordable housing construction

2. improved infrastructure

3. expanded social services

While these investments produce long-term savings, governments may struggle to fund them initially.

3. Slow Results

Unlike medical treatments, social policies take time to show results.

For example:

1. Antibiotics can cure infections within days.

2. Education policies may take 10–20 years to influence population health outcomes.

This delay can make social interventions politically difficult to prioritise.

4. Hard to Measure Impact

Health outcomes are influenced by multiple interacting factors, including:

1. genetics

2. lifestyle behaviors

3. environmental exposures

Because of this complexity, researchers often find it difficult to isolate the exact impact of specific social policies.

5. Underestimates Biological Causes

The social model sometimes places less emphasis on biological or genetic factors.

However, many diseases—such as genetic disorders or autoimmune conditions—require biomedical diagnosis and treatment.

Ignoring these factors could limit the effectiveness of health interventions.

6. Political Misalignment

A key challenge involves political decision-making cycles.

Social policies often require long-term investments, while political leaders operate within short election cycles.

As a result, governments may prioritise short-term medical interventions over long-term social reforms.

This economic and political trade-off is a major barrier to implementing the social model fully.

Advantages vs Disadvantages Summary Table

Advantages	Disadvantages
Focus on prevention	Difficult to implement
Addresses root causes of illness	High financial cost
Reduces health inequalities	Slow measurable outcomes
Holistic view of wellbeing	Hard to measure impact
Encourages cross-sector collaboration	May underestimate biological factors
Improves long-term population health	Political cycles may limit investment

 

Real-World Applications of the Social Model

Governments and global health organisations increasingly apply the social determinants of health framework in policy.

1. Housing Policies

Poor housing conditions are linked to respiratory diseases, injuries, and mental health problems.

Countries such as the UK have implemented public housing safety standards to reduce health risks.

2. Public Health Education

Education campaigns promote healthier behaviours such as:

1. smoking cessation

2. balanced diets

3. physical activity

These campaigns aim to reduce chronic diseases across entire populations.

3. Environmental Protection

Environmental policies that reduce air pollution can significantly improve public health.

For example, reducing air pollution levels can lower rates of asthma, cardiovascular disease, and lung cancer.

Workplace Safety Regulations

Labour regulations ensure safe working environments.

Modern occupational safety policies have dramatically reduced workplace injuries and deaths in many developed countries.

WHO Social Determinants Initiatives

The World Health Organization continues to promote policies addressing social determinants of health.

As of 2025, many national health strategies incorporate these frameworks to tackle health inequalities and improve population well-being.

Why the Social Model and Biomedical Model Should Work Together

The most effective healthcare systems combine both the social and biomedical models.

The biomedical model provides:

1. medical diagnosis

2. clinical treatment

3. advanced healthcare technologies

The social model provides:

1. prevention strategies

2. improved living environments

3. policies addressing social determinants

For example:

1. Doctors treat asthma with medication

2. Governments improve air quality and housing conditions

Together, these approaches produce better health outcomes than either model alone.

 Conclusion

The Social Model of Health provides a powerful framework for understanding how social and environmental conditions shape health outcomes. Its advantages include focusing on prevention, addressing root causes of disease, reducing health inequalities, and promoting long-term public health improvements. However, challenges such as high costs, slow policy outcomes, and complex implementation remain. When integrated with biomedical approaches, the social model offers one of the most effective strategies for improving population health in modern societies.
