Nutritive factor is one of the most important elements of human health in the Far North. Today historical lipid-protein nutrition character of the North aborigines is changed to the “European” type. This negatively influences the local population’s health. The aim of the study was to estimate the alimentary status and features of life (alcohol intake, smoking) of the Nenets autonomous area native population and its possible connection with cardiovascular disease risk. We have obtained data on the Nenets’ diet which is still based on proteins. We have estimated lack of fruits and green. Fast-food impacts life of the local population. Among the cardiovascular diseases, such risk factors as smoking (25 %) and alcohol intake (51 %) were presented. This category of population needs development of measures for prevention of cardiovascular and intestine pathology by nutrition correction and educational work on harm of alcohol and smoking.

Correlation properties of variations of the number of hospitalized people with cerebrovascular disorders and characteristics of solar, ionosphere and geomagnetic activity have been analyzed in the article. The hypothesis was checked, that one of the internal reasons of observed biotropical effects was the level of increased catecholamins and changes of agregative properties of blood erythrocytes. The found effects are statistically significant and specify in presence of direct influences of physical processes during indignations on blood cells. Physical processes influencing cerebrovascular shifts in humans have been discussed. It has been supposed that in a storm initial stage the stochastic resonance can be one of the physical mechanisms of external influence. External electromagnetic fluctuations can synchronize or desynchronize rhythms of electromagnetic fluctuations of blood cells. Also the possibility of direct influence of geomagnetic variations during storms on the brain and the rheological properties of blood connected with influence of an electromagnetic field on dynamics of the process of aggregation - disaggregation of erythrocytes in a blood stream as in experiments in vitro and in vivo has been discussed.

There has been done a comparative assessment of prevalence of the main symptoms of bronchial asthma (BA), allergic rhinitis (AR) and atopic dermatitis (AD) according to the standardized program «International Study of Asthma and Allergy in Children» (ISAAC) in children living in the northern and central regions of the European part of Russia. As pilot territories, there have been chosen the cities of Arkhangelsk and Kirov. There have been questioned 6 126 children aged 10-11 and 13-14 y.o., who were separated into two groups: the first group (n = 3 690, 1 813 boys and 1 877 girls) included the children living in Arkhangelsk. The second group (n = 2 436, 1 180 boys and 1 256 girls) included the schoolchildren from Kirov. The results of the study have detected high morbidity rates among the children’s population in Arkhangelsk and Kirov. The main symptoms of BA and AR among the children from the second group occurred more often than among the children from the first group. The symptoms of AD were observed more often in the representatives of the first group.

Due to recently extended views on the antioxidant system of the human organism, it becomes possible to analyze scientific data on its structure, antioxidants’ role in different processes, dependence of antioxidant activity on different factors and its methods of estimation in different tissues, a farmocorrection possibility due to pathological and age changes. As a result it has been determined that the antioxidant system includes enzyme’s and inenzyme’s antioxidants acting on the intracellular and extracellular levels and participating in many physiological processes; antioxidant activity depends on alimentary and unalimentary factors, antioxidant activity is estimated with the help of alternative methods. Problems of antioxidant activity age changes and its farmocorrection possibility are still debatable.
