Background: The growing concern of low health literacy in populations combined with the interest of companies to develop cultures of health and the emerging interest in the workplace as an arena for improving health literacy is increasingly acknowledged. This study aimed to explore how companies currently apply the concept of health literacy as part of their health efforts in the work sphere.
Methods: A systematic literature review was conducted based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analysis) guidelines. The search was performed in the databases PubMed, Science Direct, and Directory of Open Access Journals from July 2019 to August 2019 and included the search terms "health literacy," "health literate," and "health competence" combined with the search terms "company/companies," "corporation/corporates," "workplace," "business," and "organization." Studies were eligible for inclusion if they (1) were written in English or German, (2) were concerned with employers/employees, companies, corporations, or organizations, (3) dealt with health literacy in particular, and (4) were formatted as journal articles, systematic literature reviews, or book chapters.
Key results: The search identified 20 articles. A thematic analysis resulted in 5 clusters with 2 to 3 sub-themes illustrating the characteristics of how corporations apply health literacy. The clusters entailed the conceptualization of health literacy, its measurement, and the application of health literacy in strategies, interventions, and training.
Discussion: The literature review reveals that the application of health literacy by companies is in its infancy. More research and practical experience are warranted on how companies can mobilize and facilitate a health literate workforce. [HLRP: Health Literacy Research and Practice. 2021;5(3):e218-e225.] Plain Language Summary: This literature study explored the role of advancing health literacy in companies. Five aspects were identified as important, including the understanding of the concept, its measurement, and its integration into strategies, interventions, and training. The involvement of management and the staff was crucial for success.
