The antropometric and body composition examination of 500 healthy young people (17-21 years old) - residents of Barnaul and the Altai Territory countryside has been performed. Differences in physical status of the Altai Territory young people depending on residence in urban or rural areas have been detected, they were manifested in a bigger body length, weight, girth of chest, hip circumference, leg length of the city dwellers. A somatotypological analysis has revealed predominance of a normosthenic somatotype among the examined persons. Young men living in the rural areas had a more andromorphous constitution, more timely tempo of sexual development. The results will constitute a basis of the formed Altai regional database.

The article has been devoted to the analysis of the results of the study of dynamics of development of cognitive, emotional and connotative components of gender identity in boys and girls at primary school age in the period from 7-8 till 9-10 y. o. The study involved 562 junior schoolchildren, 218 of which were girls and 344 were boys. There has been determined dynamics in development of the structural components of sexual identity in the boys and girls at primary school age. It has been detected that the self-image became masculine and the image of “Most women” became feminine for the boys and girls at the age 9-10 y. o., the image of a typical male became more masculine for the boys and more androgynous for the girls at the age 9-10 y.o. It has been established that at the age 9-10 y. o. among the representatives of both sexes, there occurred a decline in femininity, the boys and girls demonstrated masculine gender role behaviors.

The suicide dynamics of three towns of the Murmansk oblast (Apatity, Kirovsk, Monchegorsk) from 1967 till 2010 has been analyzed. It has been shown that the complex of heliogeophysical and man-made factors seemed to influence the suicide dynamics in the high latitudes. The variety of suicide occurrence showed periodicities close to the main solar cycles. At the same time, a simultaneous decrease of suicide occurrence observed in three towns during 1985-1991 was probably connected with the beginning of the “anti-alcohol campaign”. A statistically significant (r s = 0,8; p = 0,005) correlation dependence of the suicide dynamics in Monchegorsk on the amount of atmospheric emissions of Cu by the biggest Russian nickel-copper smelter “Severonikel” in the period 1995-2009 has been detected.
