The authors examined 210 children aged 11-12 years for the impact of an academic process on the mental and physical health of pupils. The children were from two schools: a school with a physicomathematical bias and a general educational school. The anxiety of the children from these schools and their physical health were evaluated. The mental and physical health has been found to be currently characterized by negative trends. However, the situation is much worse at the physicomathematical school than that at the general educational one.
The authors revealed peculiarities of arterial hypertension in automobile drivers working in Far North and subjected to variety of occupational hazards, so this disease could be considered occupational entity. Facts show that work conditions of automobile drivers in Far North deteriorate course of arterial hypertension and increase importance of risk factors in its prevalence.
The study has established that only purple willow and cedar out of 23 species of the plants being examined are the most sensitive representatives of northern phytocenosis to the pollutants (heavy metals). Minimization of the air levels of pollutants and urbanized environmental sanitation require the re-orientation town-planning measures to a new scheme of creating a green plantation system, the expansion of whose area should be made in accordance with selection of plants of various species, by proceeding from the major tasks of the planting of trees and gardens and by taking into account the natural and climatic conditions for formation of ambient air pollution in this area, from the pattern of the placing and operation of structural-and-planning constructions of a town, from the morphofunctional features of representatives of northern phytocenosis to the action of man-caused impurities and environmental toxic substances. At the same time, while forming the environmental infrastructure the most important function of green plantations in the towns should be not only recreational and decorative, but also hygienic and sanitary ones that are to clear the environment from hazardous substances, to absorb gases, and to adsorb dust, which will undoubtedly promote environmental sanitation and therefore health maintenance and promotion in urban dwellers.
The paper gives the data of examination of 1333 residents from different areas of the Yamal-Nenets Autonomous District. The examination has demonstrated that oxidative process increase from south to north and from west to east, antioxidative defense becoming weaker.
The combined use of cardiointervalography and an orthostatic test allows detailed assessment of the adaptive capacities of the cardiovascular system. The paper gives the results of examination of 60 healthy adolescents from Yamal. Adjustment mechanisms have been assessed by means of hemodynamic parameters in boys and girls.
Epidemiologic examination of able-bodied population in Far North revealed time-matched averages and confidence intervals for systolic and diastolic blood pressure, pulse rate in newcomers, individuals with normal and high blood pressure. Those results enable to diagnose arterial hypertension by time-related changes in blood pressure during epidemiologic studies.

The frequency of arterial hypertension among non-native able-bodied unorganized population of Yamalo-Nenets Autonomous Okrug was studied. Mean population index of the frequency was 31.0%. Important factors which promote arterial hypertension are excessive body mass, age, period of living in the Far North, psycho-emotional stress, unsatisfactory level of adaptation and its failure, dislipidemia.
