Hygienic aspects of iodic deficiency in the children’s population of the Saratov region
AbstractThe analysis of clusters of iodine-scarce states formation among the children’s population of the Saratov Region is submitted. The hygienic assessment of iodine content in raw food materials and foodstuffs grown up and made on the territory of the Saratov Region is given. It has been revealed that various food groups were characterized by a low iodine content, which was (mcg/100 g) in the bread – 4,5±1,0; 3,6±0,8 in wheat grain; 2,7±0,6 in buckwheat; 2,5±1,1 in beans; 1,95±0,9 in peas. The actual iodine content in local vegetables and fruits was 1,3–1,6 fold below than the standard chemical composition according to the national tables, in river fish – twice. The quality analysis of the iodated salt sold in the trading network has been carried out. It has been found out that the use of the iodated salt with low iodine content has decreased the additional direct population risk from 12,34% in 2000 to 0,48% in 2010. For the last few years the use of the iodated salt tends to increase in the Saratov Region.In 2011 the iodated salt was used by 37,2% of urban population and 29,0% of villagers. In 2011 88,6% of school students were provided with the iodated salt in educational institutions of the area. It has been shown that the formation of mass iodine-scarce states among the population in the Saratov Region has lasted for a long time. The screening researches of urine excretion in the organized groups of surveyed children revealed an average level of iodine deficiency.In 2011 the iodine deficiency of moderate degree was registered in 18 areas of the Saratov Region, in 6 – of easy degree, whereas the moderately severe deficiency areas were not registered.
