Objective:To monitor iodized salt consumption and evaluate iodine deficiency status in 2014 in *** and Methods:In 2014,a nationwide cross-sectional survey was conducted in 31 provinces (in this study,provinces,autonomous regions and municipalities in China's Mainland were named as provinces).Probability proportional to size sampling method was adopted to recruit children ages 8-10 and pregnant women.47,467 children's and 18,994 pregnant women's urine samples were collected and 47,706 children's thyroid volumes were *** content in salt was determined with 46,900 edible salt samples from children's households;urinary iodine concentration (UIC) was tested from children and pregnant women's urine samples;thyroid volume of children was assessed by ***:The national coverage rate of iodized salt and consumption rate of qualified iodized salt were 96.3％ and 91.5％,*** iodine content in iodized salt was 25.2 mg/*** 22 of 31 provinces,the provincial coverage rates of iodized salt were over 95％.And consumption rates of qualified iodized salt were more than 90％ in 21 *** this study,the national median urinary iodine concentration (MUIC) of children in China was 197.9 μg/*** the provincial level,MUIC of children in 19 provinces was 100-199 μg/L,which in 12 provinces was 200-299 μg/*** national MUIC of pregnant women in 2014 was 154.6 μg/L,slightly higher than the lower limit of the WHO criteria for adequate (150-249 μg/L).At the provincial level,MUIC of pregnant women in 18 provinces was 100-149 μg/L,which in 13 provinces was 150-249 μg/*** national prevalence of goiter among children in 2014 was 2.6％,of which only Shandong province (5.6％) exceeded the national standard (5％).Conclusions:In China,iodine deficiency disorders (IDD) has been eliminated since *** in 2014,the IDD-free status still remained.

Iodization of dietary salt is recommended to prevent and control iodine deficiency disorders. The kinetic study of dietary iodized salt proves to be of interest not only for the determination of the conditions of production of iodine, but also for a good knowledge of the kinetic and thermodynamic parameters of the reaction. In this work, two salt brands were studied and one of them was used for the kinetic study. The kinetic study showed that the reaction proceeded slowly at a medium rate. Since the reaction admits a global order equal to 1, potassium iodide has no influence on this reaction rate. The concentration of iodate ions introduced in the dietary salt is a kinetic parameter that affects the reaction rate. Calculated rate constant was inversely proportional to time. The study has therefore determined experimentally kinetic parameters of the reaction between iodate and iodide ions.

The objective of this study was to assess the prevalence of iodine deficiency and possible correlated factors among schoolchildren in the municipality of Novo Cruzeiro-MG by means of an evaluation of urinary iodine excretion. Five hundred and forty schoolchildren aged 6 to 14 years selected by stratified sampling, were evaluated. Urine samples were analyzed using the Sandell-Kolthoff method preconized by the WHO and iodine concentrations in the salt were assessed by means of volumetric analysis, in accordance with recommendations from the Ministry of Health. Iodine deficiency was observed in 38.9% of the schoolchildren. Of these, 28.7% of them presented slight deficiency, 6.2% of them were moderately deficient and 4% of them were seriously deficient. Median urinary iodine levels in the urban and rural population were 150.8 and 119.2 μg/L, respectively, with a clear distribution of iodine deficiency among the populations (p < 0.001) being registered. It was also observed that there was a high prevalence of deficient urinary iodine excretion among schoolchildren that consumed salt with an insufficient iodine content. In relation to the quality of the salt consumed by families, in 12.2% of the residences studied the iodine content in salt was below the recommended level (20 mg/kg), while the iodine content was below 15 mg/kg in only 5.3% of them. The results indicated that, although not characterized as a public health issue, according to WHO criteria, iodine deficiency showed very high prevalence among schoolchildren in this region. Regarding the iodine content of salt found in household consumption, our findings indicated the National Program of Salt Iodination was not efficient in the city, since it did not hit the target proposed by the Ministry of Health. Furthermore, low urinary iodine excretion associated with the consumption of salt with low iodine content suggests the need for periodical evaluations in order to provide effective control of the endemic disease.
