[The assessment of risk factors of development of extra body mass in children of school age].

The global problems of children health include overweight and obesity and associated high risks of disability, premature death and complications of mental health in adult age. Purpose of the study is to identify alimentary and social risk factors of development of extra body mass in children and adolescents 7-17 years old residing in industrial center of the Eastern Siberia. The average age of studied group of children was 10.

[Hygienic assessment of intraschool environment in rural and urban secondary school institutions].

The purpose of the research is to assess the intra-environment indices in urban and rural secondary schools. In the course of special studies there was given the hygienic assessment of the climate, illumination and air quality of classrooms. In classrooms in rural schools microclimate indices were established to fail to meet hygienic requirements mainly on the temperature and humidity parameters.

[Hygienic assessment of the overwroughtness of educational activity in schoolchildren of 5-10 classes of secondary schools].

The state of health in children and adolescents during the time of education in secondary schools is getting worse: the prevalence rate of functional disorders and chronic diseases is increasing. There was executed the assessment of the overwroughtness of the training-education process in secondary school institutions. The prior characteristics of the educational activity are: intellectual, sensory, emotional loads; their monotony and mode of educational activity, school work intensity.

[The informativeness of indices of the heart rate variability for the identification of the adverse effects of environmental factors on the health of adolescent girls].

There was performed an investigation of informativeness of indices of the heart rate variability at rest and during orthostatic testing in the adolescent girls residing in the industrial town and in the village. The influence of unfa- vorable environmental factors was established to be reflected by the indices of the spectral analysis and cardioin- tervalography. In urban girls there was noted the marked increase of the centralization of heart rhythm control on the background of the increased activity of the sympathetic compartment and the reduction of the influence of the parasympathetic compartment of the autonomous nervous system on the sinus node.

[Features of psychophysiological status in adolescents with different intensity of sporting hours].

The experimental study of psychophysiological parameters of the central nervous system (CNS) has been performed in the adolescents who combine the learning-educational and sporting activities. The differences in psychophysiological indices in dependence on the intensity level of sporting loads have been revealed in the trained and non-trained adolescents in the presence of similar genetically determined abilities which may be determined by the force of the nervous system. The psychophysiological profile of.
