Your health isn’t just about doctors, medicines, or your DNA. It’s shaped by where you live, what you eat, how much you earn, and even the values your community holds dear. The relationship between society and health is one of the most significant yet often overlooked factors in determining individual and collective well-being. Understanding this connection is essential for anyone pursuing a career in healthcare-and for anyone who wants to live a healthier life.

What are social determinants of health?
Social determinants of health (SDOH) are the conditions in the environments where people are born, grow, work, live, and age. These non-medical factors have a profound influence on health outcomes and quality of life. According to the Centers for Disease Control and Prevention, SDOH include economic policies, social norms, political systems, and development agendas that shape daily life conditions.
Research consistently demonstrates that these social circumstances have a greater influence on health than genetic factors or even access to healthcare services. For instance, poverty is highly correlated with poorer health outcomes and a higher risk of premature death. The U.S. Department of Health and Human Services’ Healthy People 2030 initiative identifies five key domains of SDOH: healthcare access and quality, education access and quality, social and community context, economic stability, and neighborhood and built environment.
The social gradient of health
One of the most consistent findings in public health research is that health follows a social gradient-the lower the socioeconomic position, the worse the health. This pattern holds true across virtually all health indicators, from life expectancy to infant mortality to rates of chronic disease.
People with limited access to quality housing, education, social protection, and job opportunities face a higher risk of illness and death. The Pan American Health Organization notes that inequities in health are socially determined, meaning they prevent disadvantaged populations from moving up in society and reaching their full potential.
Income and health outcomes
People with higher incomes tend to be healthier and live longer than those with low incomes. They are more likely to live in safe neighborhoods, have access to nutritious foods, and find safe spaces for physical activity. Conversely, those with lower incomes face circumstances that can lead to poor health-limited healthcare access, unsafe living conditions, and chronic stress from financial insecurity.
Education as a health factor
Education level is strongly associated with health outcomes. People who have more education are more likely to live longer, participate in healthy activities like exercising and seeking regular medical care, and less likely to engage in behaviours like smoking. Education also typically leads to higher-paying jobs with benefits such as health insurance and healthier working conditions.
Cultural traditions and health beliefs
Culture profoundly shapes how people perceive health and illness, when they seek care, and how they respond to treatment. Health beliefs influence how individuals think about their health problems, from whom they seek care, and how well they adhere to treatment recommendations.
In some cultures, discussing a possible poor health outcome is believed to cause that outcome to occur. Different communities have unique practices regarding death, mourning, and healing that influence how individuals approach healthcare. Cultural factors also affect diet, physical activity patterns, and attitudes toward preventive care.
The role of cultural competence in healthcare
Cultural safety in healthcare delivery is crucial for services to be appropriate and acceptable to diverse populations. When healthcare providers lack cultural awareness, it can lead to poor decision-making and negative outcomes for patients. Training in culturally safe services should include both theoretical and practical components to help healthcare workers understand what their patients experience daily.
A person’s cultural background influences their relationship with food, their understanding of illness causation, their trust in medical systems, and their family’s role in health decisions. Healthcare that ignores these factors often fails to achieve optimal outcomes.
Political and economic systems shape health
The socioeconomic and political context determines how power and resources are distributed among different social groups. These structural determinants are considered the underlying, upstream causes of health and disease. They include poverty rates, income inequality, labour market structure, affordable housing availability, and access to essential services.
Government policies on taxation, employment, housing, and social welfare directly influence population health. Countries that allocate more resources to social services relative to medical expenditures tend to have improved health outcomes in areas such as obesity, mental health, heart disease, and diabetes.
Environmental factors and community health
Where you live matters enormously for your health. Safe housing, clean air and water, access to green spaces, and neighbourhood safety all contribute to health outcomes. Communities lacking grocery stores with healthy foods, safe areas for exercise, or reliable transportation face significant health disadvantages.
Environmental justice concerns highlight how marginalized communities often bear disproportionate burdens of pollution, unsafe housing, and lack of health-promoting infrastructure. These environmental inequities contribute directly to health disparities.
A holistic approach to health improvement
Improving population health requires looking beyond healthcare delivery to address the root causes of illness. This means integrating health improvement efforts with broader societal initiatives encompassing nutrition, environmental improvements, and education.
Health-promoting schools demonstrate this holistic approach, combining physical activity promotion, healthy eating education, and environmental changes to improve student health outcomes. These programmes recognize that sustainable health improvement requires addressing multiple factors simultaneously.
Nutrition education and food security
Access to nutritious food is fundamental to health. Nutrition education equips individuals with knowledge, skills, and ability to make healthier food choices while supporting overall learning and development. When combined with policies ensuring food access, nutrition education serves as a powerful catalyst for community health improvement.
Food insecurity and poor diet quality are closely linked to numerous negative health consequences including childhood developmental issues, chronic disease risk, and mental health problems. Addressing nutrition requires both individual education and systemic changes to food availability and affordability.
Environmental and educational investments
Investments in education yield long-term health benefits by improving health literacy, economic opportunities, and decision-making capacity. Similarly, environmental improvements-clean water systems, air quality initiatives, safe housing programmes-directly reduce disease burden and improve quality of life.
The interconnected nature of these factors means that progress in one area often supports progress in others. Better education leads to better employment, which improves income, which enables access to healthier food and safer housing.
Why this matters for healthcare professionals
Healthcare workers who understand the social determinants of health can provide more effective, patient-centred care. Rather than viewing health problems in isolation, they recognize how patients’ life circumstances influence their conditions and their ability to follow treatment plans.
This understanding enables healthcare professionals to connect patients with appropriate resources, advocate for policy changes, and design interventions that address root causes rather than just symptoms. It also helps build trust with patients from diverse backgrounds by acknowledging the real challenges they face.
The evidence linking social and cultural factors to health has grown substantially over decades of research. For healthcare systems to truly improve population health and reduce inequities, they must embrace this broader perspective and work collaboratively across sectors.
What do you think? How might understanding the social determinants of health change the way healthcare is delivered in your community? What role can nurses and other healthcare professionals play in addressing these broader factors that influence patient outcomes?
