Did you know “social determinants can be more important than health care or our genes?”

By Editorial Staff

If your doctor prescribed a new medication today—one that didn’t come in a bottle or a syringe, wasn’t dispensed from a pharmacy, and couldn’t be swallowed, injected, or inhaled—would you take it? What if it came in the form of a strong social bond, a clean street, a steady paycheck, or a sense of belonging at school or in a community? What if it were tucked inside a lunchbox packed with fruits instead of fast food, or embedded in the fresh breeze of a tree-lined neighborhood rather than the intervention of a hospital?

Imagine this: somewhere between your zip code—your environment as well as living conditions and your dinner plate, between your childhood friendships and your last job interview, lies a complex prescription pad that no doctor might have ever showed you. One that carries more to do with your well-being than your last checkup. One that continues to write itself every day of your life—without your knowledge or consent. Welcome to a different kind of diagnosis.

Social determinants of health

The World Health Organization—WHO— in its 4 October 2024 story headlined “Determinants of health” reports “Many factors combine together to affect the health of individuals and communities. Whether people are healthy or not is determined by their circumstances and environment.

To a large extent, factors such as where we live, the state of our environment, genetics, our income and education level, and our relationships with friends and family all have considerable impacts on health, whereas the more commonly considered factors such as access and use of health care services often have less of an impact.”

In another undated story by this UN agency in charge of health in the world, it explains that social determinants of health (SDH) are the non-medical factors that influence health outcomes. “They are the conditions in which people are born, grow, work, live, and age, and the wider set of forces and systems shaping the conditions of daily life. These forces and systems include economic policies and systems, development agendas, social norms, social policies and political systems.”

The WHO reveres these determinants, as far as health is concerned. “Research shows that the social determinants can be more important than health care or our genes in influencing health. For example, numerous studies suggest that SDH account for more than half of health and wellbeing.

In addition, estimates show that the contribution of sectors outside health to population health outcomes exceeds the contribution from the health sector. Addressing SDH appropriately is fundamental for improving health and reducing longstanding inequities in health, which requires action by all sectors and civil society.”

The organization emphasizes that these social factors hold a substantial share in health inequalities across the world. “The SDH have an important influence on health inequities – the unfair and avoidable differences in health status seen within and between countries. In countries at all levels of income, health and illness follow a social gradient: the lower the socioeconomic position, the worse the health.”

The list of examples of the social determinants of health, which can influence health equity in positive and negative ways include (1) income and social protection, (2) education, (3) unemployment and job insecurity, (4) working life conditions, (5) food insecurity, (6) housing, basic amenities and the environment, (7) early childhood development, (8) social inclusion and non-discrimination, (9) structural discrimination, conflict and displacement of peoples, and (10) access to affordable health services of decent quality.

The WHO summarizes the above list into three major categories namely the social and economic environment, the physical environment, and the person’s individual characteristics and behaviours. This organization highlights that reproaching a person, without first examining their context is unjustifiable. “The context of people’s lives determine their health, and so blaming individuals for having poor health or crediting them for good health is inappropriate. Individuals are unlikely to be able to directly control many of the determinants of health. These determinants—or things that make people healthy or not—include the above factors, and many others.”

It points out “Income and social status – higher income and social status are linked to better health. The greater the gap between the richest and poorest people, the greater the differences in health. Education – low education levels are linked with poor health, more stress and lower self-confidence. Physical environment – safe water and clean air, healthy workplaces, safe houses, communities and roads all contribute to good health.

Employment and working conditions – people in employment are healthier, particularly those who have more control over their working conditions. Social support networks – greater support from families, friends and communities is linked to better health. Culture – customs and traditions, and the beliefs of the family and community all affect health.”

Our health is also shaped by a complex web of factors, from our genes to  our daily habits and even our gender. “Genetics – inheritance plays a part in determining lifespan, healthiness and the likelihood of developing certain illnesses.

Personal behaviour and coping skills – balanced eating, keeping active, smoking, drinking, and how we deal with life’s stresses and challenges all affect health. Health services – access and use of services that prevent and treat disease influences health. Gender – men and women suffer from different types of diseases at different ages.”

Why zip code matters more than genetic code

Geography—neighborhood safety, pollution levels, access to healthy food, and transportation—impacts health more significantly than people often realize. In the quest to understand what truly determines health outcomes, recent research and real-world evidence have increasingly highlighted that our environment—specifically, where we live—often plays a more significant role than our genetic composition.

Genetics undoubtedly influence our susceptibility to certain diseases. However, it is the social determinants of health that reportedly predominantly dictate whether individuals get sick in the first place, how quickly they recover, and even how long they live.

Factors such as access to nutritious food, clean air and water, safe housing, quality education, reliable transportation, and economic opportunity are all shaped by our zip code. For example, individuals living in underserved neighborhoods are more likely to face exposure to environmental toxins, lack access to preventive healthcare, and experience chronic stress due to poverty or violence—all of which contribute to higher rates of disease and mortality.

Studies have shown that people living just a few miles apart can experience life expectancy differences of more than a decade, simply due to disparities in their living conditions. This underscores the urgent need to look beyond clinical settings and genetic predispositions and instead focus on improving the structural and social environments in which people live. In essence, while we cannot change our DNA— Deoxyribonucleic Acid, we can—and must—change the conditions of our communities, making zip code a critical indicator of health equity and human well-being.

DNA constitutes the molecule that carries genetic instructions for how living organisms develop, function, grow, and reproduce. You can think of DNA as the blueprint or instruction manual for life. Genetic instructions refer to the coded information inside DNA that tells cells how to build and operate the body.

When we say that genetic instructions tell cells how to build and operate the body, we mean that the DNA code provides step-by-step guidance for cells. This guidance helps them to create proteins needed to construct body structures and carry out vital functions. In simple terms, DNA acts like a giant cookbook where each gene is a recipe. These recipes guide cells in preparing the dishes—proteins — that together build, maintain, and run the entire body.

A protein forms a building block that your body uses to grow, repair, and stay healthy. It helps to perform several important jobs like building muscles, fighting sickness, and giving you energy. A gene is a small section of DNA that contains instructions to produce a specific protein or perform a specific function in the body.

Genes are the basic units of heredity — they are passed from parents to offspring and determine things like your eye color, blood type, or even your risk for certain diseases.Bottom of Form

PubMed is a search engine that primarily provides access to citations and abstracts of biomedical and life sciences literature, including research articles, clinical studies, and reviews, among others. It is maintained by the U.S. National Library of Medicine at the National Institutes of Health. PubMed contains a piece of writing entitled “Why Your ZIP Code Matters More Than Your Genetic Code: Promoting Healthy Outcomes from Mother to Child”. Though not elucidated, it is likely that it was published at the end of 2016.

Its abstract reads “Health equity has long been the dominant theme in the work of the Aetna Foundation. Recent data have focused on disparities through another lens, particularly the correlation between where people live (i.e., ZIP code) and their quality-and length-of life. In various cities across America, average life expectancies in certain communities are 20-30 years shorter than those mere miles away. In general, health disparities are founded on a complex interplay of racial, economic, educational, and other social factors.”

Aetna Foundation constitutes an American organization saying that it supports programs designed to promote wellness, health, and access to high-quality care. It adds that it places special emphasis upon health care equity, innovation in underserved communities, and cultivating a new generation of medical talent.

Time, a global media brand, echoes PubMed’s piece. Its  story titled “Americans Are Dying Younger—But Where You Live Makes a Big Difference” and released on 12 April 2023, Time says “The United States is facing the greatest divide in life expectancy across regions in the last 40 years. Research from American Inequality found that Americans born in certain areas of Mississippi and Florida may die 20 years younger than their peers born in parts of Colorado and California. The decline is not occurring equally throughout the country.

In the land of opportunity, millions of people are not even given a fair shot at life. What is driving the differences in who lives and who dies in America? The answer is wealth, demographics, and location. State policies tremendously influence life expectancy. Income support, medicaid expansion, stronger gun control, drug overdose prevention, and safe abortion access are among the drivers of regional divides in life expectancy.” Meanwhile, “Life expectancy in America is now 76 years,” says Time.

The piece of writing published by PubMed says “What is needed is an approach that considers the health and wellness of all people in a geographic area, beyond established patients, and that measures more than clinical factors-such as genetics, environmental health, social circumstances, and individual behaviors. Solutions also must extend beyond the traditional healthcare arena.”

Food, shelter, and safety: the pillars of health

Housing security, clean water, and access to nutritious food directly  influence both physical and mental health, especially for vulnerable populations like children and the elderly. These are the foundational pillars of health.

Housing security, clean water, and access to nutritious food are more than just basic needs—they are fundamental building blocks of a healthy life. When individuals and families live in stable housing, they are less likely to suffer from chronic stress. The latter one is a known contributor to a wide range of physical and mental health issues, including hypertension, anxiety, and depression. A secure home provides not only a roof over one’s head but also a sense of stability, dignity, and control over one’s environment—all essential for emotional well-being.

Clean water is equally vital. Contaminated water leads to a host of preventable diseases such as cholera, dysentery, and typhoid, which disproportionately affect low-income and marginalized communities. Access to safe drinking water ensures better hygiene, reduces the spread of infections, and supports healthy growth and cognitive development, particularly in children. The lack of it, on the other hand, can turn manageable health conditions into life-threatening ones.

Food insecurity remains a silent crisis across many regions— to understand it, read The global food crisis: factors aggravating hunger and agricultural practices, plus the solution. The absence of regular access to nutritious food leads to malnutrition, weakened immune systems, and increased vulnerability to illness. It is not just about caloric intake, but the quality of food consumed. Diets high in processed foods and low in essential nutrients can contribute to obesity, diabetes, cardiovascular diseases, and even learning difficulties in children. For the elderly, poor nutrition accelerates frailty, cognitive decline, and susceptibility to disease.

The impact is most acute among vulnerable groups like children, whose developmental years are shaped by their environments, and the elderly, whose resilience to environmental stressors diminishes over time. When these foundational needs—food, shelter, and safety—are unmet, the health consequences ripple outward, undermining not just individual well-being but entire communities.

Addressing these pillars must therefore be seen not as acts of charity but as critical investments in public health. Ensuring that every person has a safe place to live, clean water to drink, and nourishing food to eat is not just a matter of social justice—it is a preventative health measure with lasting societal benefits.

Can we prescribe community? The hidden power of belonging

Social bonds, community trust, and strong support networks buffer against mental health issues, stress, and even chronic diseases. A community represents new prescription. Social bonds, community trust, and strong support networks fulfill a critical role in shaping overall health and well-being. When individuals feel connected and supported, they are more likely to cope effectively with stress and life challenges.

Close relationships and communal support have been shown to reduce the risk of depression, anxiety, and other mental health disorders. Moreover, social integration can lead to healthier behaviors, such as increased physical activity, better sleep, and adherence to medical advice.

Communities that foster trust and mutual aid often experience lower rates of chronic illnesses like heart disease and hypertension. This illustrates that the presence of a caring and cohesive community can act as a protective factor, much like medicine. In this sense, a community represents a powerful new prescription—one that heals not only bodies but also minds.

Rethinking a health policy— a call for inter-sectoral action

While it is true that the health sector is the best placed to lead efforts in improving health, Life In Humanity argues that better health cannot be achieved by the health sector alone. It requires changes in housing policy, education systems, labor laws, environmental protection, and more. Rethinking health policy means recognizing that clinics and hospitals alone cannot fix what’s broken in our communities.

Life In Humanity emphasizes that improving health outcomes necessitates a bold shift toward inter-sectoral collaboration. Health is deeply connected to where people live, learn, work, and play—areas that often fall outside the traditional health sector. For example, substandard housing can lead to respiratory diseases, and poor education can limit knowledge about nutrition and preventive care.

Labor laws that fail to protect workers contribute to mental and physical health deterioration, particularly through job insecurity and exploitative conditions. Environmental degradation—caused by weak regulations—exposes populations to toxins, unsafe air, and climate-related health threats.

In this context, education systems are not just learning spaces but platforms for instilling lifelong health literacy. Housing policy becomes a health intervention when it ensures safety, stability, and affordability. Even urban planning and transport policies can affect physical activity levels and access to health services.

Thus, if health policies remain siloed— only managed and decided by— within ministries of health, they will always be limited in scope and impact. Life In Humanity calls for a health-in-all-policies approach, where each sector evaluates its contribution to or harm against public well-being. Only through such unified, multi-sectoral action can societies meaningfully close health gaps and build resilient, healthy populations. To truly generate a positive difference in people’s lives, health policies have to be holistic and inclusive of all development sectors, not just confined to the health ministry.
