The Persistent Challenge of Diabetes Care Inequity

Diabetes continues to impose a heavy burden on global health systems, affecting an estimated 537 million adults worldwide in 2021. While innovations in pharmacotherapy, glucose monitoring, and digital health tools have transformed clinical management, these advances have not benefited all populations equally. Racial and ethnic minorities, low-income households, and those living in rural areas consistently experience worse diabetes outcomes, including higher rates of complications, hospitalizations, and premature death. These disparities are not random or inevitable; they are the product of structural inequities embedded in how healthcare is financed, organized, and delivered. Achieving health equity in diabetes care demands intentional policy interventions and sustained advocacy to reallocate resources, redesign care delivery, and address the social conditions that shape health. Without systemic change, the gap will only widen as prevalence continues to rise.

The economic toll of diabetes is staggering, with global health expenditures exceeding $966 billion annually, yet the return on investment in prevention and management remains highly unequal. Marginalized communities often face higher out-of-pocket costs, fewer provider options, and greater logistical barriers to consistent care. Policy reforms that target these root causes are not optional—they are essential to fulfilling the promise of modern medicine for every patient. This article examines the scope of diabetes care disparities, the policy levers available to reduce them, and the critical role advocacy plays in accelerating progress.

Understanding Disparities in Diabetes Care

The Scope of the Problem

Disparities in diabetes prevalence and outcomes are well-documented and stark. African American adults are 60% more likely to be diagnosed with diabetes than non-Hispanic white adults, and Hispanic adults face a 70% higher risk. Among American Indian and Alaska Native populations, the prevalence of diabetes is roughly double the national average. These unequal rates are driven not by biology alone, but by social determinants of health—the conditions in which people are born, grow, live, work, and age. Factors such as income inequality, food insecurity, unstable housing, limited educational attainment, and inadequate access to healthcare create a compounding risk burden. For example, individuals living in food deserts often have limited access to fresh fruits and vegetables, making dietary management of diabetes exceptionally challenging. Similarly, neighborhoods with concentrated poverty frequently lack pharmacies that stock affordable insulin or primary care clinics offering diabetes self-management education.

The consequences of these disparities are measurable in life-altering complications. Racial and ethnic minorities experience significantly higher rates of diabetes-related lower-extremity amputations, end-stage kidney disease, and diabetic retinopathy leading to vision loss. The age-adjusted rate of lower-limb amputation among Black adults with diabetes is nearly four times that of white adults. These outcomes are not merely statistical anomalies—they represent preventable suffering, lost productivity, and shortened lives. The economic impact is also disproportionate: low-income individuals with diabetes spend a greater percentage of their income on healthcare-related expenses, pushing some into cycles of medical debt that further limit their ability to manage the disease.

Barriers to Quality Care

Several interrelated barriers prevent equitable access to high-quality diabetes care:

  • Access to Care: Uninsured and underinsured individuals often delay or forgo necessary medical visits, medications, and monitoring supplies. The cost of insulin has soared in many countries, sometimes forcing patients to ration doses—a dangerous practice that can precipitate diabetic ketoacidosis or death. In rural areas, the shortage of endocrinologists and certified diabetes educators forces patients to travel long distances or rely on general practitioners who may lack specialized training.
  • Health Literacy: Patients with limited English proficiency, low literacy levels, or low health literacy may struggle to interpret glucose readings, understand medication regimens, or follow dietary recommendations. Written materials commonly provided in diabetes education are frequently written at reading levels above what many patients can comprehend, creating a gap between clinical guidance and patient action.
  • Cultural Competence: Healthcare providers who are not trained to understand the cultural contexts of their patients’ lives may offer advice that is impractical or culturally misaligned. For example, dietary recommendations that assume access to specific foods or cooking equipment ignore the realities of families with limited kitchen facilities or those who rely on culturally traditional diets. Mistrust of medical institutions, rooted in historical abuses and ongoing discrimination, further erodes the patient-provider relationship.
  • Healthcare System Fragmentation: Many patients, particularly those in underserved communities, lack a stable primary care medical home. Diabetes care requires coordination across primary care, endocrinology, ophthalmology, podiatry, nutrition counseling, and pharmacy services. When these services are not integrated, patients are left to navigate the system on their own, leading to missed screenings, duplication of tests, and poor follow-up on abnormal results.

These barriers do not operate in isolation; they reinforce each other, creating a cumulative disadvantage. For instance, a low-income patient with limited health literacy who lives in a food desert and cannot afford insulin is at risk for a cascade of complications that a well-insured, health-literate patient with access to a coordinated care team can usually avoid. Addressing any single barrier in isolation is unlikely to close the gap; policy solutions must target multiple points simultaneously.

Policy Changes Needed to Reduce Disparities

Expanding Health Insurance Coverage

Financial access to care remains a foundational prerequisite for diabetes management. The Affordable Care Act’s Medicaid expansion has provided a powerful example of how coverage expansion improves outcomes. Research published in the Journal of the American Medical Association demonstrated that states opting into Medicaid expansion saw significant reductions in diabetes-related mortality compared to non-expansion states. Yet as of 2025, ten states have not adopted the expansion, leaving more than 1.5 million uninsured adults in a coverage gap—many of whom have diabetes or prediabetes. Policy advocacy must push for universal coverage in all states and for the elimination of cost-sharing for essential diabetes services. This includes zero-copay policies for insulin, glucose test strips, continuous glucose monitors (CGMs), and diabetes self-management education. Models like the Highmark Wholecare Medicaid plan in Pennsylvania, which eliminated copays for diabetes medications and supplies, have shown reductions in emergency department visits and hospitalizations, demonstrating that coverage design matters as much as coverage itself.

Strengthening Community Health Infrastructure

Community health centers (CHCs) are often the first and only point of care for underserved populations. They provide comprehensive services on a sliding-fee scale and are uniquely positioned to deliver culturally competent diabetes care. However, many CHCs operate with chronic underfunding, limiting their ability to hire certified diabetes care and education specialists, stock a full range of insulin analogs, or offer same-day appointments for acute diabetes needs. Increasing federal funding for the Community Health Center Fund is essential, as is expanding the National Health Service Corps to place more diabetes specialists in community-based settings. Policy can also incentivize CHCs to adopt team-based care models that integrate community health workers (CHWs). CHWs, who often share the same cultural background and lived experiences as the patients they serve, provide culturally tailored education, help patients set achievable behavioral goals, and connect them to social services. The CDC’s National Diabetes Prevention Program has funded CHW-led interventions in multiple states, with results showing meaningful reductions in A1c levels and hospital readmission rates. Scaling such programs requires sustained investment and changes to Medicaid reimbursement policies to cover CHW services.

Addressing Social Determinants of Health

Clinical interventions alone cannot overcome the structural forces that produce inequity. Policies must directly target poverty, housing instability, and food insecurity. The Medicare Diabetes Prevention Program offers lifestyle interventions for beneficiaries at high risk of developing diabetes, but similar benefits are often absent or limited in Medicaid programs. Policymakers should expand coverage for medically tailored meals and produce prescription programs as part of diabetes management plans. The Gus Schumacher Nutrition Incentive Program provides federal matching funds for SNAP participants to purchase fruits and vegetables at participating retailers—a strategy associated with improved dietary quality and modest improvements in glycemic control. Beyond nutrition, policies that increase the minimum wage, mandate paid sick leave, and invest in affordable housing reduce chronic stress and give individuals the time and resources needed to attend medical appointments, prepare healthy food, and exercise. When states such as California and Massachusetts implemented paid sick leave laws, researchers observed increases in the use of preventive health services among low-wage workers—a population disproportionately affected by diabetes.

Improving Data Collection and Research

Without accurate, granular data, efforts to reduce disparities risk being blind to the populations that need help most. Current health data systems often fail to capture race, ethnicity, language preference, disability status, or social risk factors in a consistent, interoperable way. The 18th National Healthcare Quality and Disparities Report from the Agency for Healthcare Research and Quality (AHRQ) underscores how data gaps hinder accountability and slow progress. Policy changes should mandate that health systems collect and report standardized data on diabetes outcomes stratified by race, ethnicity, income, and geography. Public reporting of these measures would create transparency that incentivizes health systems to address disparities. Additionally, increasing funding for disparities-focused research through mechanisms like the NIH’s Accelerating Medicines Partnership for Type 2 Diabetes can identify novel interventions tailored to high-risk populations. Research that includes community engagement from the outset is more likely to produce findings that are actionable and acceptable to the communities they aim to serve.

Regulatory and Payment Reforms

Fee-for-service payment models reward the volume of procedures and visits rather than the quality or equity of care. Transitioning to value-based payment arrangements that reward population health outcomes can create financial incentives for providers to proactively address disparities. Accountable care organizations (ACOs) that meet quality benchmarks for diabetes care—such as achieving A1c control below 8% in a high proportion of patients—could receive higher shared savings if they also reduce disparities between subgroups. The Centers for Medicare & Medicaid Services (CMS) Accountable Health Communities Model has piloted screening for unmet social needs and direct referrals to community resources. Expanding this model to state Medicaid programs and adding diabetes-specific quality measures could accelerate progress. Moreover, regulatory changes should require insurers to cover advanced diabetes technologies without discrimination. Continuous glucose monitors (CGMs) and insulin pumps improve outcomes, yet many insurers impose prior authorization hurdles or limit coverage to those with private insurance. Policies that mandate parity in coverage across public and private plans would ensure that low-income patients benefit from the same technological advances as higher-income patients.

The Role of Advocacy in Driving Change

Mobilizing Communities and Building Coalitions

Advocacy organizations are essential for translating the lived experience of patients into political will. Groups such as the American Diabetes Association, the Black Women’s Health Imperative, and the National Hispanic Medical Association conduct grassroots campaigns, mobilize affected communities, and bring patient voices directly to legislative hearings. The ADA’s #DiabetesIs campaign has highlighted real stories of individuals navigating systemic barriers, humanizing data that might otherwise remain abstract. Effective advocacy builds coalitions that extend beyond health professionals to include faith leaders, educators, small business owners, and local policymakers. Broad-based coalitions are more resilient, bring diverse perspectives, and have greater influence with elected officials who may be more responsive to a wide array of community voices. Policy change is rarely achieved by a single group alone; it is the product of sustained, coordinated efforts across sectors.

Shaping Legislation and Regulation

Advocacy operates on multiple fronts simultaneously: lobbying for new legislation, commenting on regulatory proposals, and engaging in litigation when necessary. A significant achievement was the passage of insulin copay cap bills in more than 20 states, limiting out-of-pocket costs for insured patients to $100 or less per month. On the federal level, the Inflation Reduction Act of 2022 capped insulin copays at $35 per month for Medicare beneficiaries—a victory that advocacy groups are now working to extend to the commercial insurance market and to people who are uninsured. Advocacy organizations also push for state-level diabetes action plans that set measurable goals for reducing disparities, such as reducing the rate of amputations by a certain percentage within five years. The CDC’s Diabetes State Burden Toolkit provides standardized metrics that advocates can use to track state performance. Continuous engagement is necessary to ensure that policies are not only enacted but also adequately funded and faithfully implemented. When implementation lags, advocates must escalate their efforts—through media coverage, public testimony, or even legal action—to hold agencies accountable.

Educating Stakeholders and the Public

Effective advocacy depends on a well-informed public and workforce. Healthcare providers benefit from training that helps them recognize and mitigate their own implicit biases. Advocacy organizations can partner with medical schools and professional societies to develop cultural competency curricula that are integrated into diabetes care training. Programs such as the CDC’s Do Well, Live Well with Diabetes campaign aim to reduce stigma and promote early diagnosis by reaching people where they are—on social media, in community centers, and through trusted local leaders. Translated materials, plain-language summaries, and culturally tailored messaging are essential for reaching populations with limited English proficiency or low literacy. Partnerships with media outlets, radio stations, and community influencers can amplify these messages and counteract misinformation about diabetes causes and treatments. When the public is educated about the systemic nature of disparities, there is greater support for policy solutions that address root causes rather than blaming individuals.

Monitoring and Accountability

Policy victories can be undone if implementation is weak or resources are diverted. Advocacy groups must maintain a persistent presence in monitoring how policies are put into practice. The National Quality Forum has endorsed key diabetes quality measures, including the percentage of patients with A1c levels above 9% (diabetes uncontrolled) and below 8% (diabetes with low risk). Advocates can access publicly available data through the AHRQ’s State Snapshots to track performance by state, race, and income level. Regular public reports that highlight where gaps persist create pressure for improvement. When a state or health system fails to make progress, advocacy coalitions can file complaints with oversight agencies, engage in media campaigns, or pursue legal remedies to compel action. The fight for equity does not end when a bill is signed; it requires active citizenship at every stage of the policy cycle.

Emerging Opportunities and Innovations

Telehealth and Digital Health Equity

The rapid expansion of telehealth during the COVID-19 pandemic demonstrated its potential to bridge geographic access gaps. Remote patient monitoring and virtual visits can reduce the need for travel, making it more feasible for patients in rural areas or with limited transportation to receive regular endocrine support. However, digital divides remain a persistent barrier. Low-income households are significantly less likely to have access to high-speed broadband internet or the devices needed for video visits. Policies must prioritize broadband infrastructure investment in underserved urban and rural communities. The FCC’s Affordable Connectivity Program helps reduce the cost of internet access for low-income families, but its long-term funding remains uncertain. Additionally, telehealth platforms must be designed to be accessible to individuals with disabilities, older adults, and those with limited digital literacy. Offering multilingual support and simplified interfaces can prevent the digital expansion from inadvertently deepening existing disparities.

Community-Based Participatory Research

Interventions designed in academic offices without community input often fail to resonate with the populations they intend to help. Community-based participatory research (CBPR) flips this approach by involving community members as co-investigators and decision-makers at every stage—from identifying research priorities to designing interventions to disseminating results. The Diabetes Empowerment Education Program (DEEP) exemplifies this model, training peer educators from minority communities to lead classes on diabetes self-management. Evaluations have shown that DEEP participants achieve meaningful improvements in A1c levels, self-efficacy, and quality of life. Policymakers should allocate targeted funding for CBPR initiatives within diabetes research portfolios and require that federally funded programs demonstrate meaningful community engagement. When research is grounded in the realities of the communities it seeks to serve, it is more likely to produce practical, sustainable solutions.

Cross-Sector Partnerships

Reducing diabetes disparities requires collaboration across sectors that have traditionally operated in silos. Housing authorities, school districts, transportation departments, and food assistance programs all influence the conditions under which people manage their health. The Healthy Start program in several states coordinates housing vouchers with diabetes care for pregnant women with gestational diabetes, recognizing that stable housing reduces stress and improves follow-up with medical appointments. Similarly, partnerships between health systems and food banks have shown promise in connecting patients with diabetes-friendly food supplies and nutrition education. Policy frameworks that facilitate data sharing and joint budgeting across agencies can multiply the impact of each dollar spent. The Accountable Communities for Health model, first developed in Washington State, pools funding from healthcare, public health, and social service agencies to address the holistic needs of high-risk patients. With dedicated federal support, such models could be scaled nationwide, transforming how resources are deployed to reduce disparities in diabetes care.

Conclusion

Disparities in diabetes care are neither accidental nor immutable. They arise from specific policy decisions—about who is covered by insurance, how providers are paid, which social investments are made, and whose data is tracked. The path to health equity in diabetes care is therefore a path of intentional policy reform: expanding and improving insurance coverage, investing in community health infrastructure, addressing social determinants of health, reforming payment systems to reward equity, and ensuring that data systems enable accountability at every level. Advocacy is the engine that powers this transformation. Without organized, persistent, and strategic advocacy, even the best technical policy proposals remain on the shelf. Coalitions of patients, providers, community leaders, and advocacy organizations must continue to elevate the voices of those most affected, press decision-makers for action, and hold systems accountable for results. The goal is ambitious but achievable: a future in which every person with diabetes—regardless of race, income, or geography—has access to the timely, comprehensive, and respectful care that allows them to live a full and healthy life.
