The Study Of Monitoring, Prevention And Control About Iodine Deficiency Disorders In Gansu Province

Iodine deficiency disorders (IDD) is still a public health problem in the world. Gansuprovince is one of severest IDD regions in China. In this thesis, we have collectedcorrelated information about IDD in Gansu since universal salt iodization t in 1995 andanalyzed the status and progress of IDD control and prevention in Gansu province. Westudied the iodine nutrition status of pregnant, lactating women and babies, which werepaied close attention in the world. Using most sensitive methods improved sensitivity andaccurate of detection which made the evaluation of iodine nutrition of target people morescientifically. For the first time, we carried out wide-ranging investigation and study abouthealth education status and effectiveness in Gansu province. We get some results, whichare summed up as follows:1,Since universal salt iodization t in 1995, the iodine nutrition status of children hasbeen improved and the urinary iodine of children has been optimal. The total goiter rate inschoolchildren has decreased and the consumption rate of qualified iodized salt increasedevery year, great progress has made in IDD control and prevention of Gansu. But IDDcontrol and prevention has not reached the standard of elimination and the iodine nutritionof target people was inadequate and the intelligence of schoolchildren damaged in somepoor and lagging regions.2,The main factors impacting iodized salt carrying out are the higher price of iodizedsalt, distempered marketing network in some areas and lack of IDD information in people.3,Iodine status of most of the target population for Universal Salt Iodization programis adequate, but iodine deficiency still existed in some. A positive correlation existedbetween the urinary iodine concentrations in infants and the breast milk iodineconcentrations of lactating women, which showed the breast milk iodine concentrationscan be used as a important index for assessing the iodine nutrition status of babied andmothers. A low iodine status increases the risk of thyroid function disorders, we suggestedthe urinary iodine of lactating women should be above 150μg/L.4,The progress of IDD control and prevention in center countryside was greater thanthat in village. However, IDD was still a severe healthy problem in Gansu province. IDDwas still a public health problem in Gansu province.5,The rate of qualified iodized salt, iodized salt converge rate and consumption rate of qualified iodized salt have increased every year, while non-iodized salt rate has decreasedevery year in Gansu province. The consumption rate of qualified iodized salt was 96.2% in2008. The counties with the problem of non-iodized salt rate decreased from 11 in 2001 to3 in 2008 and USI has effectively carried out in Gansu province.6, Health education was weak in Gansu. Using "materfamilias- family-community"and "school-student-community" health education pattern, the healthy education pass rateof children and women and people's behavior change rate has been improved significantly.7,Taking iodine oil can improve the status of iodine nutrition and protect newbornsnot be harm by iodine deficiency in minority region with problem of non-iodized salt.
