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).
