Variations of the geomagnetic field (GMF), whose amplitude may increase by several orders of magnitude in high latitudes during the "solar disturbance" are the main “mediator”, between solar flare and the state of living systems. It is shown, that the increase of the GMF activity are the one of the cause for the worsening health in the certain group of people and the increasing of the risk of death [10-13]. Because variations GMP modulate the functional state of the organism [14], the question naturally arises, does the solar activity and associated with it GMP variations affect on the human prenatal period? Moreover, does whether the life expectancy during prenatal and early postnatal stages depend on the phase of the SA? The literature on this subject is contradictory. In particular, one was shown that a high SA in during prenatal development and in the year of birth shortens lifespan and increases the risk of death from cardiovascular disease [3, 5, 8, 15]. On the other side, studies of Siberian scientists have shown that a high level of solar and geophysical activity during prenatal development in some extent contributes to a higher adaptive reserves of the human body and determines its suitability for living and working in regions with extreme climatic and geophysical conditions of existence [4,7]. The purpose of this study was to determine the relationship between lifespan and level of SA in the year of birth of patients Mental hospitals, as well as to make a comparative evaluation of lifespan for men and women. Materials and Methods In the material for the study is included medical and statistical data on the dates of births, deaths and causes of death in patients with psycho-neurological boarding (Regional psychoneurological boarding Apatity, Murmansk region.) To considering were selected data for the period from April 1984 to December 2009 (total of 967 cases). This set of data is unique in that all patients are identical living conditions and nutrition, which eliminates the influence of the environment and lifestyle. Years of birth people covered the period from 1895 pol984 years. The study examined the relationship between life expectancy and level of SA in year of birth. The Wolf numbers were indicators of the SA. Statistical analysis was performed using Statistika 6.0 at a significance level of p < 0,05. Figure 1 shows the contribution of diverse causes (%) that led to the death of patients Mental hospitals. One can see that the overwhelming number of deaths occur due to diverse type of cardiovascular disorders (87%). Other deaths were due to various causes, such as cachexia, cancer, epilepsy, etc. (13%). cardio-vascular insufficiency cardio pulmonary insufficiency coronary insufficiency cerebrovascular accidents other 10% Fig. 1 . The contribution of diverse causes (%) to prevalence of death cases at the boarding The average values of the Wolf numbers for the entire study period (W mean), the average values of the Wolf numbers at low (W low) and high (W high) SA have calculated by descriptive statistics are presented in Table 1. As can be seen from Table 1, the average life expectancy of people in the mental boarding is 59,5 ± 0,63 years, lifespan at birth under low SA is 63,1 ± 0,79 years, and under high CA is 54,6 ± 0,96 year. This mean, that people in group 179
