Abstract

Prevalence of thyroid diseases was researched in some categories of able-bodied citizens living in iodine deficient Tver region. On official data it is 121,6 per 1000 of working at Kalinin Atomic Power Station group, 76.1 — in ablebodied citizens of Udomlya’s District and in 52.1 — in Carbuilding Factory working citizens (p<0.01). Complex examination revealed thyroid diseases in each 5-th working citizen (130.5; 156.5 and 159.1 per 1000 of workers). Predominance of nodul and focal formations was detected on actual and on official data. Nodular goiter was detected by palpation more rare than by ultrasound scanning (9.2%; p<0.01). At the same time an enlargement of thyroid gland was detected by palpation in 16% of cases and was proved by ultrasound scanning as diffuse goiter only in 5%. In diffuse and focal changes in echostructure of thyroid gland(by ultrasound scanning) its total volume in most investigated patients did not exceed standard ranges. It needs Ultrasound Screening examination in iodine deficient region to detect real prevalence of thyroid diseases.
