[The trace element profile in children from various goiter-endemic areas of the Arkhangelsk Region].

The paper presents the results of studying the trace element status in residents from various goiter-endemic areas of the Arkhangelsk Region. It is concluded that endemic goiter in the study areas is determined by not only iodine deficiency, but also by the imbalance of thyroid-specific elements. Goiter endemic is caused by the decreased content of Se, Co, Cr, Fe, and the elevated level of Si. Moreover, an iodine-sufficient area is characterized by the lower levels of Ca, Mg, and Mn. Trace element imbalance is accounted for by the biogeochemical features of the areas under study.
