Sociocultural identity, understood as the process and result of an individuals self-identification with a historically rooted system of traditional values, normative codes, and behavioral patterns, is a key mechanism for the reproduction and integration of society. It ensures the continuity of values and semantics and serves as the basis for the development of social immunity a property of a social system that allows it to maintain integrity and stability, protecting itself from destructive external influences. In the context of youth, this identity performs a dual function: it serves as a psychological buffer, reducing the traumatic impact of external instability, and simultaneously becomes a source of meaning and strategies for actively confronting challenges. The nonlinearity of modern identification processes, characterized by the multiplicity and variability of self-determination, does not negate this function; rather, it complicates and enriches the mechanisms of immunity, creating new opportunities for personal development and forming an adaptive resource for society as a whole. The possibilities of developing youth social immunity are examined from the perspective of a socio-technological approach, which views strengthening the positive socio-cultural identity of youth as a constructive task, solved through the implementation of reproducible and measurable social practices. The target outcome of these technologies is the development of a resilient adaptive complex in the new generation, including skills for critically assessing information, resistance to destructive influences, and the ability to maintain social health.</p>","PeriodicalId":35946,"journal":{"name":"Problemy sotsial''noi gigieny i istoriia meditsiny / NII sotsial''noi gigieny, ekonomiki i upravleniia zdravookhraneniem im.

An analysis of statistical data for 2017-2023 is presented, describing the level of participation of the working population in preventive medical examinations and key parameters of employment quality, including working conditions, forms of labour relations, and social protection of workers. It is noted that there is substantial differentiation among the Central Federal District regions both in dispensarization coverage and in employment quality indicators. The study finds that regions with higher employment quality also demonstrate higher participation rates of the working population in dispensarization, supporting the hypothesis that characteristics of labour relations affect accessibility to preventive medical care. Key factors linking employment quality and dispensarization coverage are identified as the formal nature of labour relations, which enables workers to exercise their legally guaranteed right to time off for medical examinations, and employer engagement in creating conditions for staff participation in preventive activities. The article concludes that improving employment quality through strengthening social and labour guarantees and enhancing working conditions can be regarded as an important resource for increasing dispensarization coverage among the working population and, consequently, for improving public health.</p>","PeriodicalId":35946,"journal":{"name":"Problemy sotsial''noi gigieny i istoriia meditsiny / NII sotsial''noi gigieny, ekonomiki i upravleniia zdravookhraneniem im.

The theoretical methodology of the article is based on a sociological approach to professionalization, taking into account the activity-based and certification approaches.
