RESUMEN
Monitoring of Ioduria and Iodine saturation are essential tools for evaluation of effectivness of measures aimed at elimination of diseases caused by iodine deficiency. Between 1995 and 2016 monitoring of ioduria was udertaken in various population groups in Czech Republic. The most recent study (2015) found only 37 % of pregnant women in optimal range of ioduria (150-300 mcg/l), in iodopenic range 27 %, while 6 % of these had severe iodopenia below 50 mcg/l. In a group of 3y old children investigated in the same year, 57 % were found to have Ioduria within the recommended range (90-299 mcg/l), 24 % had higher than recommended Ioduria (300-499 mcg/l) and 8 % excessive saturation (over 500 mcg/l). Observed group of seniors (60-75 years) satisfied criteria for maintenance of elimination of iodine deficit of International Council for Control of Iodine Deficiency Disorders (ICCIDD), the advisory institution to World Health Organisation (WHO), as only 9 % of participants were found to have Ioduria less than 100 mcg/l and no participant had Ioduria below 50 mcg/l. Main challenges are currently stabilisation of Iodine content in milk and ensuring optimal saturation of pregnant and breast feeding women with Iodine. On-going ambition of the Inter-resort Commission for Solution of Iodine Deficit (MKJD) affiliated to the National Health Institute in Prague is to reduce and eventually eliminate diseases caused by Iodine deficiency or excess. Also, to achieve Ioduria between 100-300 mcg/l in majority of population, which would indicate adequate Iodine supply, while median of Iodurias should remain below 300 mcg/l.Key words: iodine deficiency - iodine supply - ioduria.
