A Multidimensional Analysis of Digital Health Literacy and Preventive Health Behavior in Post-Pandemic Communities

Abstract

The accelerated development of digital technologies has significantly changed how people obtain, assess, interpret, and apply health-related information. Consequently, digital health literacy has become an increasingly important capability in post-pandemic societies. This study examines the multidimensional association between digital health literacy and preventive health practices within post-pandemic communities, while also identifying the primary factors that shape this relationship. A Systematic Literature Review was conducted in accordance with the PRISMA 2020 framework. Relevant publications issued between 2020 and 2025 were retrieved from Scopus, Web of Science, PubMed, ScienceDirect, and Google Scholar. Of the 247 records initially identified, 10 empirical studies fulfilled the eligibility requirements and were included in the qualitative synthesis. The review indicates that digital health literacy encompasses several interrelated competencies, including the ability to access health information, understand digital content, critically assess its credibility, communicate health-related knowledge, and apply reliable information when making health decisions. Across the reviewed studies, individuals with stronger digital health literacy generally demonstrated greater engagement in preventive health practices, including actively seeking health information, receiving vaccinations, participating in health screenings, and complying with public health guidance. Nevertheless, unequal access to digital resources and differences in age, educational attainment, socioeconomic conditions, and technological skills remain major barriers to meaningful engagement with digital health information. These findings highlight the importance of strengthening digital health literacy through inclusive and accessible interventions to foster healthier, more resilient, and digitally empowered communities
