| Why Social Determinants of Health Matter |
When discussing health, many people
focus on medical care, diet, or exercise. But research from the U.S.
Department of Health and Human Services (HHS) shows that health is shaped
by far more than personal choices. The environments where people are born,
live, learn, work, play, worship, and age have a powerful influence on health
outcomes. These external conditions are known as the Social Determinants of
Health (SDOH)—and they play a crucial role in shaping wellness, longevity,
and quality of life.
Understanding SDOH helps us identify
why health disparities exist, how they affect communities, and what
steps can be taken to improve public health across the United States.
What
Are the 5 Social Determinants of Health?
According to HHS, SDOH are grouped
into five key domains:
- Health Care Access and Quality
- Neighborhood and Built Environment
- Social and Community Context
- Economic Stability
- Education Access and Quality
Each domain influences health in
different but interconnected ways—shaping vulnerability, exposure to risks, and
the ability to access resources.
Before going deeper, take a moment
to think about what each domain means to you and how it may influence someone’s
health. Now let’s break them down.
1.
Health Care Access and Quality
This domain focuses on the ability
to access high-quality medical care when needed.
Health outcomes are strongly influenced by:
- Physical distance from hospitals or clinics
- Availability of health insurance
- Financial capability to receive treatment
- Ability to understand health information (health
literacy)
Health literacy, as defined by HHS, refers to a person’s ability to find,
understand, and use health-related information to make informed decisions.
Additionally, organizational health literacy means how well healthcare
systems help individuals navigate services and understand medical guidance.
Without strong healthcare access and
literacy, people are more likely to delay treatment or misunderstand medical
instructions—leading to preventable health issues.
2.
Neighborhood and Built Environment
Where people live directly impacts
their safety, activity levels, and health risks.
Key factors include:
- Neighborhood safety and crime levels
- Access to clean air and safe drinking water
- Quality of housing
- Availability of sidewalks, parks, and recreational
spaces
- Exposure to environmental pollutants
Low-income communities and racial or
ethnic minorities are more likely to live in areas with safety risks or
environmental hazards. These conditions can limit physical activity, increase
exposure to harmful substances, and elevate the risk of chronic diseases.
3.
Social and Community Context
Families, social connections, and
community interactions shape emotional health, decision-making, and overall
well-being.
This domain includes:
- Family support and stability
- Community support systems
- Positive role models
- Experiences of discrimination or social isolation
- Interaction with schools, workplaces, and faith-based
organizations
Strong social support can protect
individuals—especially youth and young adults—from risky behaviors, stress, and
negative influences. Conversely, lack of support or exposure to harmful
environments increases vulnerability.
4.
Economic Stability
Economic stability directly affects one’s
ability to meet basic needs such as:
- Housing
- Food
- Healthcare
- Transportation
- Safety
Financial strain increases stress
levels and delays important medical care. People with unstable income are also
less likely to maintain regular checkups, buy medications, or follow long-term
treatment plans.
Chronic financial stress is linked
to increased risks of hypertension, anxiety, depression, and other health
complications.
5.
Education Access and Quality
Education is one of the strongest
predictors of long-term health.
Higher education levels are
associated with:
- Better-paying jobs
- Improved health literacy
- Stronger problem-solving skills
- Better long-term health outcomes
However, many children—especially
those with disabilities, from low-income families, or who experience
discrimination—face significant educational barriers. These barriers can lead
to lower academic achievement, reduced career opportunities, and long-term
health challenges.
Education influences not only career
prospects but also an individual’s ability to understand health information,
navigate healthcare systems, and make informed decisions.
Why
Social Determinants of Health Matter
SDOH explain why health outcomes
differ across communities, even when individuals have similar health
behaviors. Health is not shaped by medical care alone—it is the result of a
complex web of environmental, social, and economic conditions.
For example:
- Poor neighborhood safety reduces outdoor activity →
higher risk of obesity.
- Low health literacy leads to misunderstandings about
medication → worse chronic disease management.
- Unstable income increases stress → higher risk of
mental and cardiovascular problems.
- Limited education impacts job opportunities → long-term
financial strain and poor health outcomes.
Addressing SDOH is key to reducing
health disparities and ensuring every person has the opportunity to achieve
optimal health.
Final
Thoughts
Improving health in the United
States requires looking beyond the doctor’s office. By understanding the five
social determinants of health, individuals, communities, healthcare
providers, and policymakers can work together to create healthier, safer, and
more equitable environments.
Small changes—such as improving
health literacy, increasing community support, promoting safe neighborhoods, and
expanding access to quality education—can collectively lead to stronger,
healthier communities and better lives for millions.
