[Dynamics of epidemiological indicators of thyroid pathology in the population of the Russian Federation: analytical report for the period 2009-2018].

BACKGROUND

The level of iodine consumption by the population largery determines the spectrum of thyroid pathology. To date, in the Russian Federation, iodine-deficiency disorders (IDD) occupy a leading position in the structure of all thyroid diseases. Chronic ID leads to adverse health consequences and significant economic costs for their elimination on a national scale. However, the spectrum of thyroid pathology is not limited to the problem of ID, and the study of other thyroid diseases is also of interest.

AIMS

to assess the dynamics of prevalence and incidence of IDD and other thyroid diseases in the entire population of the RF for the period 2009-2018, using official state statistics.

MATERIALS AND METHODS

the main epidemiological indicators (incidence and prevalence) of thyroid diseases in the entire population of the RF were analyzed using official state statistics. The analyzed period is 2009-2018. There was no medical intervention. To assess the dynamics of prevalence and incidence, a linear regression models were constructed, the slope of the trend line was calculated.

RESULTS

the data were analyzed in accordance with the structure of diseases presented in the statistical reporting: goiter, thyroiditis, hypothyroidism, thyrotoxicosis, congenital iodine deficiency syndrome. For the ten-year period 2009-2018 there is a statistically significant increase in the prevalence of various forms of goiter, thyrotoxicosis, congenital iodine deficiency syndrome in the entire population of the Russian Federation. During the observation period, an increase in the incidence of thyrotoxicosis was revealed. With regard to the incidence of congenital iodine deficiency syndrome, only an upward trend was revealed. Despite the fact that during the observation period the number of new cases of various forms of goiter decreased, the prevalence of goiter among the population of the Russian Federation remains high: 1.2% of the population by January 1, 2019. with the growth of autoimmune pathology, improvement of the level of diagnosis, and also, in some cases, with overdiagnosis (for example, when diagnosing autoimmune thyroiditis in individuals with asymptomatic carriage of antithyroid antibodies). The current approaches to iodine prophylaxis are not effective enough.

CONCLUSIONS

the results of the analysis indicate mainly an increase in the high prevalence of thyroid pathology among the population of the RF against the background of regional events. The problem of ID remains unresolved, which dictates the need to introduce universal mandatory salt iodization in the territory of the RF.
