RESUMO
There was performed the determination of the characteristics of the physical development of 660 girls aged of from 6 years 6 months to 17years 5 months 29 days, residing in the Blagoveshchenskiy and the Ust-Pristanskiy regions of the Altai Krai. The Blagoveshchenskiy region is characterized by a high level of ambient air pollution (potential of the atmospheric pollution accounts for 2.7-3.0). Sodium sulfate, sulfur dioxide, hydrogen sulfide, carbonic oxide, nitrogen dioxide, vanadium pentoxide, ammonia, manganese and its compounds, hexavalent chromium make the greatest contribution to the atmospheric pollution. The Ust-Pristanskiy region is referred to the least polluted territories of the Altai Krai. Living conditions in the Blagoveshchenskiy region of the Altai Krai were found to influence on the girls ' physical and sexual development. The girls living in the Blagoveshchenskiy region show the pubertal growth spurt one year later, which is lasting longer. As a result, by the age of 17, measurements of the body and leg length are almost 6 cm higher in girls of the Blagoveshchenskiy region. 97% of the Blagoveshchenskiy region residents have pathological (trochanter index ≤ 1.85) and disevolutive (trochanter index = 1.86 - 1.91) types of age evolution which testifies to the thyroid and reproductive hormones deficiency. Among the residents of the Ust-Pristanskiy region, 80% have either normal values of the trochanter index (1.95 - 2.0) or slightly deviated from the norm (hypoevolutive, normoevolutive, and hyperevolutive types of age evolution). The level of the endocrine system diseases prevalence, nutrition and metabolic disorders among the teenagers of the Blagoveshchenskiy region are 2.5 times higher than in the rural area of the Altai Krai. The relative risk of the endocrine system diseases occurrence, nutrition disturbances and metabolic disorders in the teenagers of the Blagoveshchenskiy region equals to OR=1.87 (x=272.7, p<0.001).
