The age transformations of thyroid size at the children and teenagers from the Slavgorod's area

Statistical data processing of the screen investigates of 1638 children and teenagers from the Slavgorod's area of the Mogilev Region is conducted. Ultrasonic diagnostics was used to determine the quantitative objective laws of the thyroid gland volume changes depending on age of the surveyed persons. It was used the method of the standard statistical analysis of data, which was received with the screen survey of the healthy children and children from contamination region. Thyroid gland biometrics was conducted by the Toshiba SSA-240A ultrasonic scanner by Brunn et al. technique. Linear dependence of total volume, volume of a left and right share of the thyroid gland from age and floor surveyed was established. Comparison this results with data, received from 'clean' regions, as well as in Germany and Sweden too, permits to expand representation about age changes of the thyroid gland volume and leads to a conclusion, that the increase of the thyroid gland volume at teenagers in the most degree is defined by iodine insufficiency. For girls the thyroid gland volume are more, than for boys in all age groups, and it was detected excess of volume of a right share in comparison with volume of a left share, which is more expressed at girls too
