In underserved communities across the globe, barriers to healthcare often go far beyond distance or cost. They are deeply rooted in inequities in education and health literacy, all factors that silently shape whether individuals understand their symptoms, how they navigate health systems, or whether they seek care at all. Education is not merely a social determinant of health, but it is a powerful, actionable strategy to transform access. When people are equipped with the knowledge on how to inquire, care and advocate for their illness and wellbeing, they become empowered, and in turn, entire communities are strengthened.
Education is the First Step Towards Health Equity
According to the World Health Organization (2024), health literacy includes the ability of individuals to think critically in order to access, understand, appraise and use information and services in ways that promote and maintain good health and well-being.
It is not merely the ability to access web sites and read pamphlets.
Furthermore, the Center for Disease Control (CDC) stated that nearly 9 out of 10 adults in the United States struggle to understand and use personal or public health information effectively, leading to avoidable hospitalizations, medication errors, and preventable complications. This number is even more frightening in the developing world.
Low health literacy disproportionately affects underserved populations, compounding existing barriers such as limited provider availability or transportation. Improving population health literacy is often the first and most cost-effective intervention to increase timely access to care and reduce disparities. Individuals with higher health literacy usually have better health outcomes.
The Power of Community Health Workers
One of the most effective strategies is the training of Community Health Workers (CHW). As highly visible personnel, these individuals (often from the same communities they serve) are trained to provide basic medical education, promote preventive care, and link patients with formal healthcare systems.
Evidence from the U.S. and low- and middle-income countries shows that CHW programs can improve health outcomes, reduce hospital readmissions, improve maternal-child health outcomes, and increase adherence to chronic disease management plans (Viswanathan et al., 2009).
Prominent examples of such efforts include India’s Accredited Social Health Activist (ASHA) program which trains rural women to deliver maternal and child health services; and the University of New Mexico developed Project ECHO that offers tele-mentoring to CHWs in remote areas, building their capacity to address complex conditions like diabetes, mental health disorders, and substance use.
These models work because education is multiplied when one trained individual can impact hundreds of lives.
Community School-Based Health Hubs
Health education doesn’t begin in the clinic, it often starts in the classroom. School-based health initiatives are an increasingly vital way to reach underserved children and families, especially where schools are trusted institutions.
The Elev8 program in Baltimore is one such model. It integrates school-based clinics, health education, and family engagement in middle schools. Results show increased use of preventive services and improved academic outcomes, demonstrating how educational investment translates into both health and social gains.
Beyond programs, simply embedding age-appropriate health topics in the school curriculum like nutrition, sexual health, or emotional well-being, can build lifelong habits that reduce disease burden and improve community health over time.
Keeping Up With the Digital Age
As digital health tools expand without corresponding digital literacy, they risk deepening inequity. Underserved populations, particularly older adults, low-income households, and rural residents, often lack the skills or confidence to use telehealth platforms even when access is available.
Educational outreach in this area isn’t just about teaching health technologies, it’s about reducing fear, building trust, and creating a pathway for virtual care to reach the people who need it most.
What This Means
To sustainably improve healthcare access, there must be investment in education as a health system priority.
This means:
• Funding Community Health Worker education programs with formal training and ongoing support
• Embedding effective health education in schools and teacher training
• Developing a digital literacy curricula for underserved populations
• Measuring health literacy as a core performance indicator in healthcare systems
The return on investment in such efforts is undeniable. One review found that health literacy interventions yielded improvements in both health outcomes and healthcare utilization across most evaluated studies (Nutbeam et al., 2020).
For policymakers, healthcare leaders, and funders, the message is clear; education is not an accessory to healthcare delivery, it is foundational.
Final Thoughts
The path to equitable care doesn’t rely on hospitals, insurance policies, or mobile clinics only. It begins in classrooms, community centers, and with meaningful conversations that inspire the transformation of this knowledge into power. We must remain committed to spotlighting innovation, policy, and partnerships that elevate education as a tool for health equity. But in the fight for access, education is more than just a tool, it is part of the solution.
