Introduction. Given the generally accepted definition of the term "health" as "a state of complete physical, mental and social well-being, and not only the absence of diseases and physical defects," it becomes obvious that the subjective assessment of health by the person himself must be taken into account. Among the main indicators of health, a special position is occupied by its subjective assessment by the population. The purpose - to analyze the subjective assessment of their own health by the population of various regions of the Republic of Kazakhstan. Materials and methods. The data for this study were obtained by including 1,500 people living in the northern (n=500), western (n=500) and southern (n=500) regions of the Republic of Kazakhstan. The study was conducted using a questionnaire method based on the questionnaire of N.V. Yurgel et al. (2009), which included a set of questions, one of which was designed to subjectively assess the respondents' own health. Results. One in three respondents rated their health status as satisfactory (36.9%) and good (28.9%). The features of the subjective assessment of health status depending on the region of residence and age are established. Thus, the maximum number of respondents with a good assessment of their own health was observed in the northern regions of the Republic of Kazakhstan (53.2%) and at the age of 18-39 years (31.3%); and the minimum number of respondents with the same level of subjective assessment of health status was found in the southern regions and in the age group of 40-64 years (24.2%). Conclusion. The data obtained indicate a different level of subjective assessment of the own health of the population living in different territories of the Republic of Kazakhstan. The development of the research can be aimed at creating regional models that integrate objective (medical-statistical) and subjective (medical-sociological) data.
