JUSTIFICATION OF METHODOLOGICAL APPROACHES TO STUDIES OF HEALTHY LIFE EXPECTANCY IN PERSONS OVER WORKING AGE
Background. In recent years, our country has begun to pay certain attention to the issues of healthy life expectancy. However, there are practically no publications devoted to the study of healthy life expectancy (hereinafter referred to as HLE) in older age groups. In view of this, the study of healthy life expectancy in persons older than working age is of current interest. Aim: development of methodological approaches to the study of HLE in persons over working age. Material and methods. For the purpose of studying the HLE in people over working age, 507 people over 60 years of age, living in Kazan city, were examined using a specially designed card (according to the WHO guidelines). The presence of chronic diseases, disability, and the proportion of persons in good and poor health were considered. The methodology was used to assess activity, as well as the presence of limitations in persons over the working age on a scale from 1 to 5 points. Results and discussion . The Sullivan study of the health status in persons over working age showed that at the age of 60 years old, 45,2% of those examined had poor health, at the age of 65 years - 59,1%, at the age of 70 years - 71,4%, and at the age of 75 years - 78,3%; all those examined at the age of 80 and older had poor health. At the same time, life expectancy rates (hereinafter, LER) were (12,3±1,458) years at age 60, and only (2,5±0,693) years at age 85 or older. The HLE values had a significant decrease depending on the age. Thus, if at the age of 60 years the HLE was (4,5±0,847) years, at the age of 80 years and older none of the examined persons had a healthy life expectancy, which indicates a reliable decrease in the quality of life in these persons depending on age. Conclusion. The health status in persons over working age starting at age 60 decreases significantly from 54,8% to 21,7% at age 75, and at age 80 and older the health status of these persons is reduced to a minimum. The HLE at age 60 decreased from (12,3±1,333) years to (2,5±0,693) years at age 85 or older. The study showed a healthy life expectancy of (4,5±0,847) years at age 60 years and no healthy life expectancy at age 80 years or older. A significant decrease in the quality of life indicates the need to develop measures to protect health and to improve the quality of life in persons older than working age.
