Basic Concepts of Health Literacy for Equitable Thai Health Systems

Abstract

Health literacy refers to individual knowledge and competencies needed to access, understand,
appraise, and apply health information for making health related decisions in order to maintain and
improve health for oneself and others. It accumulates throughout the life course through daily activities
and social interactions. Health literacy is influenced not only by individual factors, but also organizational
structures and availability of resources. Therefore, health systems have direct effects on health literacy
among people. With a health literacy friendly health system, people will improve their health literacy and
be able to utilize available health related resources. In contrast, there might be an increasing proportion
of the population with limited health literacy left behind. The rate of utilization of basic preventive and
promotive health services will drop while that of curative services will rise and the health systems cannot
handle the situation. This special article presents the basic concepts of health literacy and enabling factors
for improving Thai health systems to become health literate and promote health equity. The content
covers health literacy as the national agenda, organizational health literacy, health literacy as a modifiable
determinant of health, and health literacy as an empowering factor. Furthermore, enabling factors for
health literacy friendly health systems are elaborated such as health literacy workforce, health literate
organization, health literacy data management, shared decision making in health services, partnerships,
technology and innovation for health literacy, financial support and investment, and health literacy
leadership. These basic concepts have been drawn from theories and practices from various countries.
They will help policy makers, healthcare professionals, and technical health workers to develop equitable
health systems to achieve the goal of the national strategic plan.
