On the question of the justification of regional population standards of “quality of life” related with the health of children and adolescents (on the example of the Omsk region)

Currently, many developed countries have produced and applied population standards of quality of life, which are used as health status indices in formulating preventive measures and assessing their effectiveness. The study of children and adolescents quality of life is important, as it is one of the population health status indices. In this research, the population standards of adolescents quality of life were studied and justified on an example of Omsk region as a large administrative-territorial unit in the Western Siberia. The research was implemented in compliance with the methodology for the study quality of life. The general well-being quality of life questionnaire PedsQL 4.0. was used as the primary tools. We have investigated the quality of life of 427 students of secondary schools aged 13 to 17 years, residing in the city of Omsk and Omsk region. Among the surveyed were 183 boys and 244 girls. The median values and the 25^th and 75^th percentiles for the individual scales were: physical functioning (FF) to 87.5 (71.9–100.0) points, emotional functioning (EF) — 70.0 (50.0–85.0) points, social functioning (SF) — 95.0 (75.0-100.0) points, school life (SL) — 70.0 (55.0–90.0) points, psychosocial health (PH) — 76.7 (63.3–88.3) points and the total score (TS) was 81.5 (67.4–90.2) points. The peculiarities of formation of indices were studied depending on the gender of the subject, the area of residence and their state of health. The adolescents with a chronic disease in remission and attending the educational institution were determined to have the lower quality of life rates by reducing physical functioning. The relative distribution of quality of life indices for the individual scales of the questionnaire does not depend on the area of residence; there is an evidence of the existence of the formation of quality of life indices regularities and their relations among themselves. The results of the study are characterized by the sensitivity and reproducibility, which allowed designating the obtained values as regional population-based standards of quality of life.
