BACKGROUND: The Bryansk region is one of the regions of the Russian Federation most affected by the accident at the Chernobyl nuclear power plant on April 26, 1986.In the conditions of a chronic uncompensated deficiency of iodine in the diet in the first months after the accident, an active seizure of radioactive iodine by the thyroid tissue took place, which inevitably resulted in an increase in thyroid diseases from the population in the future. The article presents the results of a control and epidemiological study carried out in May 2021 by specialists of the National Medical Research Center of Endocrinology of the Ministry of Health of Russia, aimed at assessing the current state of iodine provision in the population of the Bryansk region.AIM: Assessment of iodine supply of the population of the Bryansk region.MATERIALS AND METHODS: The research was carried out in secondary schools of three districts of the Bryansk region (Bryansk, Novozybkov and Klintsy).The study included 337 schoolchildren of pre-pubertal age (8–10 years), all children underwent: measurement of height and weight immediately before the doctor’s examination, which included palpation of the thyroid gland (thyroid gland); Thyroid ultrasound using a portable device LOGIQe (China) with a multi-frequency linear transducer 10–15 MHz; determination of iodine concentration in single portions of urine. A qualitative study for the presence of potassium iodate in samples of table salt (n = 344) obtained from households and school canteens was carried out on the spot using the express method.RESULTS: According to the results of a survey of 337 pre-pubertal children, the median urinary iodine concentration (mCIM) is 98.3 μg / L (range from 91.5 to 111.5 μg / L, the proportion of urine samples with a reduced iodine concentration was 50.1%). According to the ultrasound of the thyroid gland, 17% of the examined children had diffuse goiter, the frequency of which varied from 9.4 to 29% in the areas of study. The share of iodized salt consumed in the families of schoolchildren in the study areas was 17.8% (values range from 15.6 to 19%), which indicates an extremely low level of iodized salt consumption by the population. All salt used for cooking in school canteen areas of the study was iodized, which confirms compliance with the requirements of SanPiN 2.4.5.2409–08.CONCLUSION: Despite the active implementation in the Bryansk region of various preventive programs of IDD and social activities to promote the use of iodized salt, in the absence of mass prevention with the help of iodized salt to date, their unsatisfactory results should be noted.

Background: The article presents the results of a control and epidemiological study conducted in September 2020 by specialists of the Federal State Budgetary Institution «NMIC of Endocrinology» of the Ministry of Health of Russia, aimed at assessing the current state of iodine provision in the population of the Republic of Crimea. The study in Crimea is part of a number of activities and work carried out on behalf of the Ministry of Health of the Russian Federation within the framework of state assignments «Scientific assessment of the need for additional regulatory legal and other measures to eliminate iodine deficiency in pilot regions with severe iodine deficiency» and «Epidemiological and molecular-cellular characteristics of tumor, autoimmune and iodine deficiency thyropathies as a basis for prevention of complications and personalization of treatment.The data obtained reflect the state of the problem of iodine consumption on the territory of the Crimean Peninsula and indicate the relevance of the adoption of a regional preventive program aimed at eliminating iodine deficiency in the diet of the population and related diseases.Aim: Assessment of iodine supply of the population of the Republic of CrimeaMaterials and methods: The research was carried out in secondary schools of four districts of the Republic of Crimea — in the years. Simferopol, Belogorsk, Bakhchisarai and Saki.The volume of the study — 356 schoolchildren of 8-10 years old, all were completed: taking anamnesis and anthropometric parameters (height, weight), examination by an endocrinologist with palpation of the thyroid gland (thyroid gland), ultrasound examination of the thyroid gland (thyroid ultrasound), obtaining single portions of urine and samples of table salt (5-10 grams), which is used daily in the diet in their families. The measurements of the height and weight of the children by the standard method were carried out during the examination by a specialist. Thyroid ultrasound was performed in the supine position using a portable LOGIQe ultrasound machine (China) with a 10-15 MHz multifrequency linear transducer. All urine samples (n = 356) in disposable Eppendorf microtubes were immediately frozen at a temperature of minus 20-25°! for further determination of the concentration of iodine in urine using the cerium-arsenite method (based on the clinical diagnostic laboratory of the Federal State Budgetary Institution NMITs endocrinology «of the Ministry of Health of Russia). A qualitative study for the presence of potassium iodate in food table salt samples (n = 203) was carried out on site by the express method.Informed consent was obtained from all parents / guardians of children for the examination and processing of personal data. The permission of the local ethical committee of the Federal State Budgetary Institution «NMIC of Endocrinology» of the Ministry of Health of Russia was received on March 25, 2020, No. 5.Results: According to the results of a survey of 356 children of primary school age, the median concentration of iodine in urine (mCIM) is 97 pg / l and varies from 78 to 98 pg / l in the surveyed areas, the proportion of urine samples with a reduced iodine concentration was 51.2%. The share of iodized salt use in the families of schoolchildren was 12.3% (values range from 10% to 15%). The average incidence of goiter in children according to ultrasound data is 9.5% (range of values from 1.7% to 16.3%).Conclusion.The indicator of the median concentration of iodine in urine indicates an insufficient iodine supply of the population of the Republic of Crimea.The prevalence of goiter in children of primary school age according to the ultrasound examination of the thyroid gland corresponds to the mild severity of iodine deficiency in the mild degree of goiter endemic in the region.The share of households using iodized salt is extremely low and amounts to 12.3%, which does not meet the WHO recommendations for regions with natural iodine deficiency (from 90% or more).

The strategy for the elimination of diseases associated with iodine deficiency throughout the Russian Federation is based on the adoption of a federal law providing for the use of iodized salt as a means of mass (population) iodine prophylaxis. Chronic iodine deficiency that exists in Russia leads to dramatic consequences: the development of mental and physical retardation in children, cretinism, thyroid diseases, and infertility. Under conditions of iodine deficiency, the risk of radiation-induced thyroid cancer in children in the event of nuclear disasters increases hundreds of times. By definition, all iodine deficiency diseases (IDDs) can be prevented, while changes caused by iodine deficiency during fetal development and in early childhood are irreversible and practically defy treatment and rehabilitation. The actual average consumption of iodine by a resident of Russia is only 40–80 mcg per day, which is 3 times less than the established norm (150–250 mcg). Every year, more than 1.5 million adults and 650 thousand children with various thyroid diseases turn to medical institutions. The cause of 65% of cases of thyroid disease in adults and 95% in children is insufficient intake of iodine from the diet. At the stage of preparing the relevant legislative act, the development and implementation of regional programs for the prevention of IDD is of utmost importance. A typical draft of such a program is proposed in this article for its adaptation and use at the regional level.
