Annotation The changes of the endocrine system activity, characteristics of sexual and physical development in adolescents of Khabarovsk and Amursk cities are discussed in this article. In children, living in the ecologically unfavorable environment (Amursk), the retardation of sexual development for 1–2 years, in comparison with the children of the same age in the control group (Khabarovsk) is revealed. The disorders of physical development such as disharmonious development in 40 % of Amursk city adolescents, because of body mass deficiency are defined. In control group, disharmonious development was due to low (in boys) and high (in girls) parameters of chest circumference. The estimation of physical development revealed the predominance of average level in adolescents of Amursk city group (63,5 %). In control group (Khabarovsk) 70 % of adolescents have high level of physical development. The blood serum content of some hormones (adeno – hypophysis, glucocorticoids, sexual and thyroid) in Amursk group and Khabarovsk group is correlatively connected with the sexual development characteristics (secondary sexual features).
