In the article materials showing the growing influence of both school and extra-school factors on health of children and adolescents are presented. Special attention is given to the main classes of school-related diseases. Aim. To justify reasonability of studying this problem in Astrakhan within the frames of complex approach to application of health-saving technologies. Conclusion. Problems described in the article are characteristic of practically any region of Russia, in this connection a significant number of studies are carried out in Astrakhan region devoted to issues of protection of childrens health and to investigation of exposure of children to environmental factors. With this, absence of works on evaluation of complex use of health-saving technologies in terms of their influence on health of schoolchildren, permits to consider such hygienic studies actual.

At the present stage, carrying out laboratory monitoring of the presence and concentrations of all known harmful chemicals within the framework of socio-hygienic monitoring is technically impossible, due to their extremely large number. At the same time, for most chemical compounds and elements, the nature and degree of their impact on human health, as well as the pathologies caused by them, have been scientifically established [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]. The so-called ecologically dependent diseases are most determined with environmental quality parameters [11]. The paper presents the results of the use of an inter-regional comparative analysis of the incidence of the child population by individual environmentally dependent pathologies, which makes it possible to identify priority classes of diseases and nosological forms for the region, the occurrence and development of which is caused by air pollution. Considering the nature of the incidence of these pathological conditions as an indicator of the possible presence of harmful substances in the atmospheric air, this approach can be used to compile a list of priority pollutants to be controlled in a particular region, which will increase the reliability of assessing the quality of the air environment in the framework of social and hygienic monitoring.

Introduction. The purpose of the study was to scientifically substantiate the unification of methods for analyzing the morbidity of the population, and comparative analysis of the morbidity of the child population at the interregional level within the framework of social and hygienic monitoring. Objective. The scientific substantiation of the feasibility of an inter-regional comparative analysis of the incidence of the population in the constituent entities of the Russian Federatio to increase the efficiency and effectiveness of management decisions developed as part of social and hygienic monitoring. Material and methods. A comparative analysis of the incidence in the regions of the Southern Federal District, the occurrence and development of which is associated with air pollution, was carried out. Statistical data processing was performed by linear regression using the Statgraphics and Microsoft Excel software packages. The calculation of the Pearson correlation coefficient r to evaluate the severity of the existing trend in the variation of the variation series and the determination coefficient (R2), taking into account the reliability coefficient p <0.05. Assessed approaches to the analysis of the incidence of children in the framework of socio-hygienic monitoring in the subjects. Results. The study revealed the lack of a unified approach to the analysis of the morbidity of the population in the constituent entities of the Russian Federation within the framework of socio-hygienic monitoring, both according to the criteria for determining the priority pathologies for the region, and the duration of the analyzed period. The comparative analysis of the morbidity of the child population at the interregional level showed a significant difference in the dynamics and levels of morbidity from ecologically caused pathologies in adjacent regions, with similar social and climatic parameters. The formation of human health takes place under the conditions of the multicomponent influence of various factors. The etiology of most of the nosological forms, the degree of their dependence on the state of the external environment have been scientifically established. The most determined by the components of the environment, ecologically caused pathologies, the nature of the incidence of which is considered by the authors as a possible manifestation of the impact of a specific factor that has a priority value in the occurrence and development of these diseases. Conclusions. The study shows the expediency of unifying methods for analyzing the incidence of the population, as well as conducting a comparative analysis of the incidence of the child population at the interregional level within the framework of socio-hygienic monitoring.
