Introduction: Iodine deficiency is one of the most important public health problems in the world. It mostly affects pregnant women and children. The lack of iodine leads to an increase in the numbers of perinatal mortality and mental retardation.
Material and methods: In 2012-2014, a survey was carried out of 2,342 women, of whom 2284 were analyzed for salt to measure the content of iodine, and 2,242 women of reproductive age had their urine samples analyzed by the cerium-arsenite method based on the Sandell-Kolthoff reaction. Determination of the medical and social effectiveness of biological monitoring of IDS was carried out in 3 stages.
Results: The study revealed that in the eastern Kazakhstan region the relative risk (RR) of overall prevalence of iodine deficiency among women was 1.1 times higher (95% ID: 0.35-3.61; Z statistic = 0.192) among household respondents (≤15mkg/kg). In the Pavlodar region, the RR of the prevalence of total iodine deficiency is 0.5 times higher in households where the salt was not sufficiently iodized. In the Zhambyl region the RR of the iodine deficiency prevalence was about twice as high due to insufficient iodized salt.
Conclusions: The introduction of biological monitoring of IDS among women, especially pregnant women, may positively affect the detection of the risk limits for the birth of infants with reduced mental abilities or other diseases during pregnancy, using timely targeted preventive measures to exclude factors that affect the spread of IDS.
