title: [The age dynamic of hormonal levels in children living in different latitudes in European North].
abstract: An investigation simultaneously of hormonal profile in children of 10-16 years living in different latitudes and climato-ecological conditions in Russian European North (in the border of polar and middle latitudes) was performed. The increased thyrotropin level was revealed in 35% of children in the south (61 degrees North) and in 32% of children in the North (64 degrees 30' North). The thyroid hormones (thyroxin, triiodothyronine) are at low normative bound. Higher Insulin levels were observed in 28% of children living in the southen region especially in 50% of prepubertal boys. In 20% of children, higher cortisol levels were revealed mainly at the final puberty (35% of children).
