Background.
The economic and social significance of the population's health literacy (HL) and areas of practical application of the results of its research are shown. An analysis of the conceptual apparatus and methodology for studying medical awareness and HL, the history of the development of the WHO unified approach, and the transformation of the understanding of the various components of HL as a complex phenomenon was carried out. It has been established that from a methodological point of view, HL is a dynamic construct. Approaches to its measurement and assessment vary; definition outweighs transformation. Despite the unification methodology carried out by WHO, there are always national, cultural and social specificities in the study.
Aim: to substantiate the methodology for studying and assessing the medical awareness and health literacy of the population (HL), to reveal the prospects for the development of this scientific area, taking into account global trends and the scope of application of the results.
Materials and methods: a systematic review of publications and open access Internet sources of the RSCI, Springer, WHO portal, and others databases was carried out.
Results: In modern study methods, mandatory and optional components are distinguished. An isolated study of only the mandatory component gives an idea of the availability of medical information for the population, without taking into account its subsequent use - thus, this component, most often referred to by the term “general health literacy - GHL”, is essentially medical awareness. By analyzing the main and additional components, the researcher has the opportunity to assess the GHL, taking into account the national and social specifics of the respondents, as well as deepen the study in aspects of digital, organizational, vaccinal and other forms of HL. The dynamism of the concept of group restrictions makes it possible to supplement the tools, while the specifics of the additional component can and should take into account the subsequent practical applicability of the study results.
Conclusion: the study of HL in the population is promising from an organizational, medical and social point of view; the research process itself is a factor motivating respondents to preserve health.
