Quick answer: Social determinants of health (SDOH) are the non-medical conditions that shape a person’s health outcomes and include things like where they live, their income, education level, and access to care. Research shows these factors drive up to 80% of a person’s health, making them essential knowledge for every healthcare provider.
You treat the patient in front of you. But what about the conditions that brought them to your door in the first place?
For decades, healthcare has focused on clinical interventions: medications, procedures, screenings, etc. These are vital. But a growing body of evidence shows that the environment a person grows up and lives in can matter just as much as the care they receive. According to the World Health Organization (WHO), social determinants of health are “the non-medical factors that influence health outcomes—conditions in which people are born, grow, work, live, and age” (WHO, 2024).
Understanding these factors doesn’t just expand your clinical knowledge. It changes how you care for patients, and it can close gaps that medicine alone can’t.
This post breaks down the five social determinants of health identified by the Healthy People 2030 initiative, explores their impact on chronic disease and community health, and outlines practical steps you can take at the patient, practice, and community level.

What are the five social determinants of health?
Healthy People 2030 identifies five distinct domains of social determinants of health:
- Neighborhood and built environment: Housing quality, access to transportation, crime rates, environmental conditions, and green spaces
- Economic stability: Income, employment, poverty, and access to affordable housing
- Healthcare access and quality: Insurance coverage, availability of services, and health literacy
- Education access and quality: Early childhood education, school quality, and language literacy
- Social and community context: Social connectedness, civic participation, access to social services, and rates of incarceration
These aren’t abstract categories. They show up directly in your patients’ lives and in your exam rooms.
How does where someone lives affect their health?
Where a person lives is one of the most powerful predictors of health outcomes. Life expectancy can vary by up to 20 years between zip codes in the same city.
Poor housing quality increases children’s risk of respiratory diseases, developmental disorders, preterm birth, and low birth weight. Housing instability also correlates with more missed school days and reduced readiness to learn.
Access to transportation plays a similar role. Without reliable public transit, patients miss appointments, struggle to reach grocery stores, and lose access to economic opportunities. Areas far from healthy food options, known as food deserts, face higher rates of obesity, diabetes, and cardiovascular disease.
Environmental exposures add another layer of risk. Pest infestation, lead exposure, and inadequate ventilation all contribute to chronic health conditions, particularly in individuals with asthma, COPD, or compromised immune systems.
What this means for your practice: Routinely asking patients about their housing, transportation, and neighborhood safety can surface critical context that shapes their care plan. Questions like “Do you have a stable place to live?” or “Has lack of transportation kept you from getting what you need?” take seconds and can change everything.
How does economic stability shape health outcomes?
Nearly 38 million Americans were living in poverty in 2022, approximately 11.5% of the population (U.S. Census Bureau, 2024). Poverty is concentrated, persistent, and often multigenerational.
The health consequences are significant. Men in the top 1% of income are expected to live 14.6 years longer than men in the bottom 1%. People with lower incomes have reduced access to healthcare, healthy food, and safe environments for exercise. They’re also more likely to work physically demanding jobs with limited opportunity for growth.
Food insecurity compounds these risks. According to the USDA (2023), 12.8% of U.S. households (approximately 17 million) were food insecure at some point in 2022. Food-insecure children show lower academic achievement, more behavioral difficulties, and higher rates of anemia and hypercholesterolemia. Among older adults, food insecurity is significantly associated with falls.
Approximately 18.5% of the U.S. population lacks health insurance, and nearly 70% of uninsured individuals are poor or near-poor. Without insurance, patients delay care, skip screenings, and rely on emergency departments rather than primary care, contributing to a cycle that worsens outcomes and drives up costs.
What role does healthcare access play in health disparities?
Access to care isn’t just about proximity to a clinic. It involves insurance coverage, health literacy, language barriers, cultural trust, transportation, and clinic hours.
About 1 in 10 Americans lacks health insurance, with cost cited as the primary barrier. Uninsured individuals are far less likely to receive preventive screenings. A 2018 study found that women who were never insured were 41% less likely to receive breast cancer screening and 47% less likely to receive colorectal cancer screening. Men who were never insured were 52% less likely to receive colorectal screening.
Health literacy adds another layer. The CDC defines health literacy as “the degree to which individuals have the ability to find, understand, and use information and services to inform health-related decisions” (CDC, 2023). Nearly 9 out of 10 adults struggle with complex health information. Poor health literacy is associated with higher hospitalization rates, increased healthcare costs, and worse outcomes.
Improving health literacy could prevent approximately one million hospital visits and save over $25 billion annually (CDC, 2023). That’s a compelling case for clear communication in every patient interaction.

How does education affect long-term health?
The relationship between education and health is well established and significant. Adults with higher education levels live longer, healthier lives. Research shows that the odds of death decrease by 1% to 3% with each additional year of education. If everyone experienced the mortality rates of college graduates, 50% of all male deaths and 40% of all female deaths would not occur (Oates et al., 2017).
Education influences health through several pathways:
- Higher education tends to lead to better-paying, more stable jobs
- Greater income supports access to healthy food, quality housing, and healthcare
- Higher education correlates with stronger social support systems and better stress management
- People with more education are more likely to engage in health-promoting behaviors
The relationship runs in both directions. Poor health can create educational setbacks. Children with chronic conditions like asthma miss more school days. Likewise, children with ADHD are nearly three times more likely to drop out before graduation.
Why does social connectedness matter for patient health?
Social isolation isn’t just uncomfortable; it’s a health risk. Among older adults, social isolation is associated with increased mortality (Singer, 2018). Quality of social support, research suggests, matters more than the quantity of connections.
For adolescents, connectedness to family, school, and community reduces depression, anxiety, suicidal ideation, and risky behaviors. For young children, positive stimulation from caregivers is essential for cognitive and language development. The landmark Spitz study of 1944 demonstrated starkly that infants whose physical needs were met yet were deprived of meaningful human contact developed significantly worse outcomes than those with consistent caregiver relationships.
Social context also shapes behaviors that directly cause disease. Smoking, for example, is a social behavior. Growing up in a household where someone smokes, having a partner who smokes, or regularly socializing with smokers all increase the likelihood of smoking initiation. People from socially disadvantaged communities face greater barriers to cessation, including stress, financial strain, and reduced access to care.
How did COVID-19 reveal the impact of social determinants?
The COVID-19 pandemic made visible what researchers had long documented. Communities with lower incomes, less stable housing, and fewer resources experienced significantly worse outcomes.
A University of Chicago study found that twice as many individuals in low-income groups lost wages in the first months of the pandemic compared to higher-income groups. Overcrowded housing made social distancing impossible. Closure of food banks, support groups, early childhood programs, and routine care created cascading health consequences. By May 2020, routine vaccination rates among children under age 2 had dropped below 50%.
Individuals with addiction were particularly vulnerable, as they faced homelessness, lack of insurance, and loss of peer support groups that were critical to recovery (Grinspoon, 2020). The pandemic didn’t create these disparities, but it did amplified them.

How can healthcare providers reduce health disparities?
Healthcare providers can take meaningful action at three levels.
At the patient level
Screen for social needs as part of routine care. Tools like the CMS Accountable Health Communities (AHC) Health-Related Social Needs (HRSN) Screening Tool and the PRAPARE assessment help identify risks related to housing, food security, transportation, utilities, and financial strain. Over 40% of socially disadvantaged patients report that their primary care provider was unaware of their situation (Andermann, 2016).
Ask questions with empathy. A supportive, culturally respectful approach encourages patients to share what is really going on. Once the patient has identified a need, connect patients with local resources like food banks, housing assistance, Medicaid enrollment, and community services.
At the practice level
Organizational changes can reduce structural barriers to care. Consider:
- Offering extended clinic hours for working patients
- Providing interpreter services
- Reimbursing transportation costs
- Opening satellite locations near underserved communities
- Using patient navigators to help individuals access services
At the community level
Healthcare providers can partner with public health officials, educators, and community organizations to advocate for systemic change. Supporting policies that promote affordable housing, living wages, and access to healthy food creates healthier environments for entire populations. Local research can identify community-specific SDOH and guide targeted interventions.
Start addressing social determinants in your practice today
Social determinants of health are not background noise. They’re fundamental drivers of your patients’ health. Socioeconomic factors, environmental conditions, and health-related behaviors together account for up to 80% of a person’s health outcomes.
Awareness is the first step. The next is action: asking better questions, making smarter referrals, and advocating for the conditions that allow every patient to thrive.
Frequently asked questions
What are social determinants of health?
Social determinants of health (SDOH) are the non-medical conditions that influence a person’s health outcomes. According to the WHO (2024), these include the conditions in which people are born, grow, work, live, and age, spanning economic systems, social norms, and political structures. The five main SDOH domains, as defined by Healthy People 2030, are neighborhood and built environment, economic stability, healthcare access and quality, education access and quality, and social and community context.
Why are social determinants of health important for nurses and doctors?
Healthcare providers who understand social determinants of health can deliver more accurate diagnoses, develop more effective care plans, and connect patients to resources that address root causes of poor health. Over 40% of socially disadvantaged patients report that their primary care provider was unaware of their social challenges. Identifying these factors early leads to better outcomes and reduced healthcare costs.
How do social determinants of health affect chronic disease?
Social determinants directly shape the risk, course, and outcomes of chronic diseases including cardiovascular disease, diabetes, cancer, COPD, and chronic kidney disease. For example, limited access to healthy food increases the risk of obesity and diabetes. Lower socioeconomic status is associated with higher rates of lung cancer, even after controlling for smoking history. Social context determines not just disease exposure but also how well patients can manage conditions once diagnosed.
What tools can healthcare providers use to screen for social needs?
Two widely used tools are the Accountable Health Communities (AHC) Health-Related Social Needs (HRSN) Screening Tool, developed by CMS, and the PRAPARE (Protocol for Responding to and Assessing Patients’ Assets, Risks, and Experiences) assessment. Both evaluate needs related to housing, food security, transportation, financial strain, and community support. Results should be documented in the patient’s medical record so the entire care team can respond effectively.
What is health literacy, and how does it relate to social determinants?
Health literacy refers to a person’s ability to find, understand, and use health information to make informed decisions (CDC, 2023). It’s closely tied to education access, a core SDOH domain. Low health literacy is associated with higher hospitalization rates and worse health outcomes. Nearly 9 out of 10 adults struggle with complex health information. Improving health literacy could prevent approximately one million hospital visits and save over $25 billion annually.
How can individual healthcare providers take action on social determinants?
At the individual level, providers can routinely screen for social needs, ask about patients’ living situations and food access, communicate with empathy and cultural sensitivity, and refer patients to community resources. Organizations can extend clinic hours, offer interpreter services, and use patient navigators at the practice level. At the community level, providers can partner with public health organizations and advocate for policy changes that address the root causes of health inequity.
