Abstract

This study aims to evaluate the current prevalence of iodine deficiency diseases (IDD) among the organized population of the Republic of Karakalpakstan. An epidemiological survey was conducted, involving a random sample of 299 children from schools and kindergartens. A total of 250 urine samples were collected from children aged 4-6 and 11-15 to assess iodine levels quantitatively. The prevalence of diffuse goiter was found to be 19.4%, with 14.7% of the children diagnosed with 1st degree diffuse goiter and 4.7% with 2nd degree diffuse goiter. Ioduria analysis indicated that 57.2% of the samples had iodine deficiency (20-99 μg/l), 29.3% had adequate iodine levels (100-200 μg/l), and 13.7% had more than adequate iodine levels (>200 μg/l). Historical data from 1998 to 2014 showed a decrease in diffuse goiter prevalence from 71% to 56% and a reduction in severe iodine deficiency from 94.5% to 4.4%. The proportion of table salt meeting GOST standards increased to 43.1% in 2004 but decreased to 30% by 2013. The findings indicate a significant iodine deficiency among children in Karakalpakstan, with over 50% showing inadequate iodine levels. Despite past improvements, the current iodine status remains concerning. This necessitates stringent monitoring, improved quality control of iodized salt, and measures to ensure sufficient dietary iodine intake. Regular epidemiological assessments and enhanced production controls are crucial to prevent low-quality iodized salt from entering the market and to address the ongoing IDD issue in the region.
