Social Determinants of Health

Key Points

• Social determinants of health (SDOH) are the conditions in which individuals are born, live, work, play, worship, and age — they shape health outcomes as powerfully as biological factors.
• Healthy People 2030 organizes SDOH into five domains: economic stability, education access and quality, health care access and quality, neighborhood and built environment, and social and community context.
• Health disparities are differences in health outcomes between population groups — often driven by structural barriers such as systemic inequities and socioeconomic disadvantage.
• Health care disparities refer specifically to differences in access to care and insurance coverage that worsen outcomes and costs.
• Nurses assess SDOH at every patient encounter to identify barriers to care and connect clients to appropriate resources.
• Advocacy, culturally competent care, and interdisciplinary collaboration are core nursing strategies for addressing SDOH.
• SDOH also shape daily safety exposure (home hazards, neighborhood risk, work strain) and the ability to implement prevention plans.

Pathophysiology

SDOH do not cause disease directly but create conditions of chronic stress, limited access to resources, and cumulative disadvantage that increase risk for chronic disease, mental health disorders, and premature death. Lower socioeconomic status (SES) is consistently associated with higher rates of cardiovascular disease, diabetes, respiratory illness, and reduced life expectancy. Environmental exposures (poor housing, food deserts, pollution), lack of insurance, and limited health literacy create barriers that compound over time — a phenomenon known as the cumulative effect of inequalities. SDOH also influence whether individuals can access practical safety infrastructure such as public safety systems, emergency response, and local health services.

Five Domains of SDOH (Healthy People 2030)

Domain	Examples of Factors
Economic stability	Income, poverty, employment, food security, housing stability
Education access and quality	Early childhood education, high school graduation, higher education access, health literacy
Health care access and quality	Insurance coverage, proximity to providers, quality of care, cultural competency
Neighborhood and built environment	Housing quality, access to nutritious food, transportation, environmental toxins, neighborhood safety
Social and community context	Social support networks, civic engagement, discrimination, incarceration, social isolation

Disparity Terminology

• Health disparity: Difference in health outcomes linked to entrenched social, economic, political, and environmental inequities.
• Health care disparity: Difference in health care access, affordability, or coverage that limits receipt of quality care.
• Trust-barrier disparity: Historical and ongoing discrimination can reduce preventive-care engagement and delay treatment.

Nursing Assessment

NCLEX Focus

SDOH assessment goes beyond vital signs. Screening questions about food security, housing stability, transportation, and social support are essential components of holistic care — and directly affect treatment adherence and health outcomes.

SDOH screening in clinical practice:

• Food security: “In the past 12 months, did you worry that food would run out before you had money to buy more?”
• Housing stability: “Do you have stable, safe housing?”
• Utilities/basic needs: “Do you have reliable access to clean water, refrigeration, and utilities needed for food safety and daily living?”
• Transportation: “Do you have difficulty getting to medical appointments?”
• Social support: “Do you have people you can count on for support?”
• Literacy and language: Assess health literacy with plain-language communication; identify need for interpreter services
• Insurance and access: Assess current coverage status and recent delays in obtaining primary, preventive, or maternal care services.
• Strengths and supports: Assess protective factors such as reliable transport, stable primary-care linkage, or family/community support to build feasible equity-focused plans.
• Safety context: Assess whether living/working environments create added risk for falls, injury, infection exposure, or delayed emergency response.

Populations with elevated SDOH burden:

• Persons with low SES, racial and ethnic minorities, rural residents, uninsured or underinsured clients
• Non-Hispanic Black clients: higher cardiovascular disease death rates
• Hispanic adults: highest rates of uninsured and unmet medical care needs
• Adults without high school diploma: four times more likely to smoke than college graduates

Nursing Interventions

Assessment and connection to resources:

• Conduct SDOH screening at every encounter using structured tools
• Connect clients to community resources: food banks, housing assistance, transportation programs, financial counseling, social work referrals
• In food-insecurity or food-desert contexts, prioritize actionable nutrition-access planning (transport options, local affordable sources, and emergency food linkage).
• In substandard-housing contexts, escalate for housing/utility support when unsafe conditions (overcrowding, lack of heat/running water, toxin exposure) threaten health.
• Refer to case management for clients with complex social needs affecting care continuity
• Use public disparity resources (for example AHRQ national quality/disparity data and OMH/REACH community supports) to guide local referral and quality-improvement priorities
• Link eligible patients to employment skills programs, childcare supports, and food/housing assistance when economic instability drives access failure.
• Support policy advocacy for upstream determinants (for example early-childhood education access, paid leave, and safe labor standards) when these gaps repeatedly drive poor outcomes.
• Use transportation-support pathways (for example ride vouchers or partner transit programs) to reduce missed visits and medication lapses.
• Expand access supports through primary-care linkage, telehealth options, wait-time reduction workflow, and health-information exchange when coordination barriers are identified.
• Promote neighborhood health supports (green spaces, safe activity areas, and local fresh-food access) through community partnerships and referral mapping.

Culturally competent care:

• Provide care that is sensitive, respectful, and inclusive of cultural, linguistic, and religious practices
• Advocate for interpreter services; avoid using family members as medical interpreters when confidentiality or accuracy is at risk
• Adapt education materials to the client’s health literacy level using health literacy principles and plain language

Advocacy:

• Advocate for policies that promote equitable access to health care, education, and housing
• Participate in interdisciplinary teams and community partnerships to address systemic barriers
• Report patterns of health disparity within the health care system and support quality improvement initiatives

Health Literacy and Adherence

Clients with low health literacy are at significantly higher risk for medication errors, missed follow-up, and preventable hospitalizations. Always assess understanding using “teach-back” before discharge and provide written materials at ≤6th-grade reading level.
