Objective
To reveal the intellectual framework, research trends, and gaps, and evaluate effective health literacy tools in the field of primary healthcare services.
Design
Observational, machine learning-based bibliometric study.
Site
Analysis was conducted using records indexed in the Web of Science database.
Participants
A total of 1,869 researchers from 823 institutions across 54 countries contributed to the 33 journals included in the dataset.
Interventions
Development of a bibliometric map and topic model in health literacy within primary healthcare. Bibliometric analysis was performed on review and research articles retrieved as of July 27, 2025. For each article, data on the journal, publication year, title, abstract, keywords, authors, affiliations, countries, cited sources, cited first authors, and references were collected. Latent Dirichlet Allocation topic modeling was applied to uncover thematic structures and trends in the research field.
Main Measurements
Thematic structures, research trends, and knowledge gaps were measured through bibliometric indicators such as co-authorship networks, citation analysis, and topic modeling outputs.
Results
Emerging topics included health equity and sustainability, medication adherence, aging, management of lifestyle factors such as physical activity and diet, management of chronic diseases, physician-patient communication, sustainable learning, sociodemographic impact, rural health interventions, responses to pandemics akin to COVID-19, and the roles of health institutions, policymakers, and leadership.
Conclusions
Our findings highlight that health literacy is a multifaceted concept that not only enables healthier living and disease management but also prevents various severe health conditions, improving overall life quality and satisfaction with health services. The importance of sustained health literacy initiatives, effective communication, and the vested interests of both patients and healthcare professionals are highlighted, underscoring the need for ongoing commitment in this area.
