Social Determinants of Health at Work: Why Benefits Alone Don’t Drive Health Outcomes

Employer Health Strategy

25 min read

Quick Answer

What are social determinants of health, and why should employers care? Social determinants of health (SDOH) are the nonmedical conditions that shape health outcomes—economic stability, education, healthcare access, neighborhood environment, and social context. According to the National Academy of Medicine, these factors account for an estimated 80–90% of modifiable health outcomes. For employers, this means that even the most comprehensive health plan won’t improve workforce health if employees face food insecurity, housing instability, transportation barriers, or financial stress outside the workplace.

An employer offers a generous health plan. The network is broad, the deductibles are reasonable, the formulary is competitive. By traditional measures, the benefits package is strong.

And yet: ER utilization stays high. Chronic condition management is poor. Preventive care engagement is low. Absenteeism persists. The plan is good on paper, but health outcomes aren’t improving.

This disconnect has a name. It’s not a failure of benefits design—it’s the influence of social determinants of health (SDOH), the nonmedical factors that shape whether people can actually use the benefits they’re offered. The conditions in which employees live, commute, eat, manage stress, and raise their families have a far greater impact on their health than the plan document sitting in their inbox.

Understanding SDOH isn’t optional for employers who want their health investments to produce results. It’s the difference between spending money on coverage and spending money on outcomes.

The U.S. Department of Health and Human Services, through Healthy People 2030, defines five key SDOH domains. The CDC, adapting the World Health Organization’s framework, describes SDOH as the conditions in which people are born, grow, work, live, and age—conditions shaped by the distribution of money, power, and resources.

The National Academy of Medicine estimates that medical care accounts for only 10–20% of modifiable health outcomes. The remaining 80–90% are driven by health behaviors, socioeconomic factors, and environmental conditions—the factors these five domains capture.

SDOH Domain	What It Covers	Workforce Examples
Economic Stability	Employment, income, expenses, debt, food security, housing stability	Employees living paycheck to paycheck, choosing between prescriptions and rent, unable to afford copays
Education Access and Quality	Literacy, language, early childhood education, vocational training, health literacy	Workers who can’t navigate the health system, don’t understand plan documents, or can’t read EOBs
Healthcare Access and Quality	Insurance coverage, provider availability, cultural competency, transportation to care	Employees with coverage who can’t get time off for appointments, lack transportation, or live in provider deserts
Neighborhood and Built Environment	Housing quality, transportation infrastructure, air/water quality, food access, safety	Workers in food deserts, with long commutes, in polluted or unsafe housing, without walkable neighborhoods
Social and Community Context	Social integration, community engagement, discrimination, incarceration history, stress	Isolated remote workers, employees experiencing discrimination, those without social support systems

These domains don’t exist in silos. An employee earning low wages (economic stability) in a neighborhood without grocery stores (built environment) who can’t take time off for a doctor’s visit (healthcare access) and lacks family support (social context) faces compounding disadvantages that no health plan alone can resolve.

Why Employers Can’t Ignore SDOH

The business case for addressing SDOH is grounded in data, not sentiment.

Research published in the American Journal of Managed Care (2022) found that lower-salary employees enrolled in high-deductible health plans had higher rates of preventable emergency department visits and avoidable inpatient admissions, but lower rates of outpatient and preventive care utilization—suggesting the plan structure itself was discouraging routine care among those who needed it most.

U.S. Census Bureau analysis found that individuals from lower-income households visited emergency rooms for preventable reasons approximately 2.5 times more often than those with higher incomes. CDC data from the Behavioral Risk Factor Surveillance System showed that lower-income adults consistently had lower utilization rates for preventive services across nearly every category measured—from cancer screenings to routine checkups.

A 2024 study in JAMA Network Open examining the Medical Expenditure Panel Survey’s SDOH module found direct associations between social determinants and healthcare expenditures across Medicare, Medicaid, and private insurance. Factors including educational attainment, social isolation, and medical discrimination were all independently linked to higher costs.

The implication for employers is clear: health plan spending increases when employees face unmet social needs. Investing in benefits without addressing the conditions that drive utilization patterns produces diminishing returns.

SDOH Exist in Every Workforce—Not Just Low-Income Ones

A common misconception is that SDOH only affect low-wage workers. In reality, social determinants exist across income levels, though they manifest differently.

Across the Income Spectrum

Entry-level and hourly workers face the most visible SDOH challenges: food insecurity, housing instability, transportation barriers, inability to take time off for medical care, and high sensitivity to out-of-pocket costs that discourage preventive care use.

Mid-career salaried employees may face childcare gaps that prevent appointment attendance, caregiving responsibilities for aging parents, financial stress from student debt or housing costs in high-cost markets, and social isolation in remote work arrangements.

Senior professionals and managers aren’t immune. Chronic work stress, sleep disruption from demanding schedules, social isolation in leadership roles, substance use, and delayed preventive care due to “too busy” culture all represent SDOH factors that affect health outcomes regardless of income.

Common SDOH Patterns in Employer Populations

Food insecurity: USDA reported that 47.4 million people lived in food-insecure households in 2023. This includes working adults—employed people whose wages don’t cover consistent access to nutritious food.
Transportation barriers: Employees who can’t reliably get to medical appointments miss preventive care, delay treatment, and end up in the ER for manageable conditions.
Digital access limitations: Telehealth adoption requires reliable internet and a private space. Workers without broadband, or who share living spaces without privacy, can’t effectively use virtual care—even when the plan covers it.
Childcare and caregiving: Employees who can’t arrange childcare or elder care coverage during business hours skip medical appointments, miss wellness screenings, and defer care until it becomes urgent.
Financial stress: Workers facing debt, unpredictable expenses, or cost-of-living pressure defer copays, skip prescriptions, and avoid care they perceive as discretionary—even when it’s covered by their plan.

What Employers Can Do About SDOH

Addressing social determinants doesn’t require employers to solve systemic poverty. It requires recognizing which SDOH factors affect their specific workforce and designing targeted interventions.

Economic Stability Interventions

Financial wellness programs: Emergency savings tools, financial counseling, student loan assistance, and budgeting resources address the financial stress that drives care avoidance.
Living wage assessment: Evaluating whether compensation keeps pace with local cost of living—particularly for hourly and entry-level roles—directly affects whether employees can afford to use their benefits.
Predictable scheduling: For shift workers, predictable schedules enable appointment planning. Irregular schedules make preventive care nearly impossible.

Healthcare Access Interventions

Telehealth as a default: Virtual care removes transportation and time-off barriers. Making telehealth the first-line access point—not an afterthought—addresses geographic and scheduling constraints.
Transportation support: Ride-share partnerships, transit subsidies, or mobile health services bring care to employees who can’t get to it.
Onsite or near-site clinics: Placing primary care where employees already are eliminates the biggest access barrier: time away from work.

Expanded EAP programs: Employee Assistance Programs that address not just mental health but also legal, financial, housing, and family challenges connect employees to resources for unmet social needs.
Community resource partnerships: Partnering with local food banks, housing assistance programs, childcare cooperatives, and social services agencies creates pathways for employees with needs the employer can’t directly meet.
Social connection initiatives: For remote and distributed workforces, structured social interaction—mentorship, peer groups, team rituals—counters the isolation that contributes to poor mental health outcomes.

Built Environment and Workplace Design

Healthy food access: Workplace cafeterias with nutritious options, subsidized healthy meals, or fresh food delivery partnerships address food insecurity during the workday.
Active design: Walkable campuses, standing desks, and exercise facilities remove barriers to physical activity during the workday.
Indoor environment quality: Air quality, natural light, noise control, and ergonomic design affect daily health in ways that compound over years.

How Data Identifies SDOH Patterns in Your Workforce

Addressing SDOH effectively requires understanding which determinants affect your specific employee population. Several data sources can reveal patterns without exposing individual health information.

Aggregate Claims Analysis

Claims data—analyzed at the population level, not the individual level—can reveal SDOH-related patterns. High rates of ER utilization for non-emergency conditions, low preventive care engagement, medication non-adherence (prescriptions filled but not refilled), and avoidable hospitalizations all correlate with unmet social needs. These patterns, viewed in aggregate, tell employers where benefits are underutilized and why.

Health Risk Assessments with SDOH Screening

Adding validated SDOH screening questions to voluntary health risk assessments—covering food security, housing stability, transportation access, financial stress, and social support—generates direct data about unmet needs. Participation must be genuinely voluntary, data must be anonymized, and results should be reported only in aggregate to protect privacy.

Geographic and Demographic Analysis

Mapping employee zip codes against publicly available data—food desert maps from the USDA, Area Deprivation Index scores, provider density data from HRSA—identifies where employees live in relation to healthcare access, healthy food, and other resources. This analysis uses no protected health information and reveals structural barriers the employer can address through benefits design.

Absenteeism and Utilization Correlation

Correlating anonymized, aggregate absence patterns with claims utilization data can identify workforce segments where social needs may be driving both poor health and poor attendance. High absenteeism combined with low preventive care and high ER use in a specific employee segment is a strong SDOH signal.

Designing Benefits with SDOH in Mind

Traditional benefits design optimizes for coverage. SDOH-informed design optimizes for access—recognizing that a benefit employees can’t practically use is a benefit that doesn’t improve outcomes.

Telehealth for geographic barriers: Making virtual care available 24/7 with low or no copay addresses the reality that many employees can’t take two hours off work to visit a doctor’s office.
Transportation to appointments: Ride-share benefits, transit passes, or mileage reimbursement for medical visits turn theoretical coverage into practical access.
Food insecurity screening and referral: Integrating SDOH screening into wellness programs identifies employees who need food assistance and connects them to community resources—intervening before nutrition-related chronic disease develops.
Financial counseling as a health benefit: Financial stress is one of the strongest predictors of poor health outcomes. Embedding financial counseling into the benefits package addresses a root cause, not just a symptom.
Flexible care scheduling: Paid time off specifically for medical appointments, or coverage of after-hours and weekend urgent care, acknowledges that rigid work schedules are themselves a healthcare access barrier.
Low-barrier mental health access: Mental health benefits that require no referral, have $0 copay for initial visits, and include text/chat-based options remove the friction that prevents employees from seeking help.

How Population Health Research Informs SDOH Strategy

Understanding SDOH at the workforce level requires data. And collecting, analyzing, and interpreting health-related data at the population level—while protecting individual privacy—is fundamentally a research challenge.

This is where employer-sponsored health research programs play a role. By systematically collecting health data from consenting participants, analyzing patterns across a defined population, and producing aggregate insights, research programs can identify which SDOH factors are most prevalent and most impactful in a specific workforce.

The distinction from traditional benefits administration is important: research programs are designed to identify patterns and generate knowledge, not to make individual coverage decisions. They ask questions like “what percentage of our population lives in a food desert?” or “is there a correlation between zip code and ER utilization in our plan data?”—questions whose answers inform benefits strategy without exposing anyone’s individual health information.

Organizations that combine robust health plan coverage with structured research into the social conditions affecting their workforce are better positioned to design benefits that actually improve outcomes—because they’re working from evidence about their specific population, not assumptions about a generic one.

Frequently Asked Questions

The five SDOH domains defined by Healthy People 2030 (U.S. Department of Health and Human Services) are: economic stability, education access and quality, healthcare access and quality, neighborhood and built environment, and social and community context. Together, these nonmedical factors shape an estimated 80–90% of modifiable health outcomes.

SDOH influence whether employees can effectively use their health benefits. Workers facing food insecurity, transportation barriers, financial stress, or caregiving gaps underutilize preventive care, overuse emergency services, and experience more chronic conditions—driving up plan costs while producing poor health outcomes despite adequate coverage.

Can employers legally screen for SDOH?

Yes, as part of voluntary health risk assessments or wellness programs, with appropriate privacy protections. SDOH screening must be genuinely voluntary (per ADA and EEOC guidelines), data must be kept confidential and separate from employment records, and results should be reported only in aggregate. Employers should consult benefits counsel when designing screening programs.

What’s the difference between SDOH and wellness programs?

Traditional wellness programs focus on individual health behaviors (exercise, diet, smoking cessation). SDOH-informed approaches address the structural conditions that make healthy behaviors possible or impossible—income, food access, transportation, housing, and social support. Effective programs integrate both: behavior change support within a framework that addresses the barriers to change.

Key Takeaways

Medical care accounts for only 10–20% of modifiable health outcomes. The remaining 80–90% are driven by SDOH—economic stability, education, healthcare access, neighborhood environment, and social context.
Generous health benefits alone don’t improve workforce health if employees face barriers to actually using them. SDOH explain the gap between coverage and outcomes.
Lower-income workers visit ERs for preventable reasons approximately 2.5 times more often than higher-income individuals, while consistently underutilizing preventive care—patterns driven by social conditions, not plan design.
SDOH exist across income levels. Financial stress, caregiving gaps, social isolation, and schedule inflexibility affect mid-career and senior employees too.
Employers can address SDOH through targeted interventions: financial wellness, telehealth, transportation support, EAP expansion, community partnerships, and SDOH-informed benefits design.
Population-level data—from claims analysis, SDOH screening, and geographic mapping—identifies which determinants affect a specific workforce, enabling evidence-based strategy instead of guesswork.
