The level of the national household salt iodine Surveillance

The proportion of> 5 up to 22 provinces. Coefficient of variation of iodine content of iodized salt in 30% of the province is still up to 2o, of which up to 68.2 in Hainan Province, which indicates that the uniformity of iodized salt is not ideal. Some provinces 60mg/kg of iodized salt ratio was more than 2O, Shanxi, Jiangsu> 60mg/kg of iodine rates were 34.7,22.2, Tibet, Hainan <2omg / kg of iodized salt ratios are 46.5,21.5. This also underscores the unevenness of the problem of iodine salt. 2.31997,1999 salt iodine monitoring data on comparative analysis] in terms of overall evaluation of the provinces or from the national results, the quality of iodized salt has a more substantial improvements and enhancements. In addition to iodized salt, the coefficient of variation of Shanxi,[link widoczny dla zalogowanych], the provinces were gradually decreased, indicating that the iodine in iodized salt have a certain uniformity to improve; iodized pass rate of 18 provinces, increasing year by year, an increase of 13 provinces, more than 30 percentage points more than 2o percent increase in 7 provinces. But it is worth noting that there are five provinces of iodized salt coverage lower than in 1997, which dropped 20.9 Shanxi, Hainan dropped 18.00/oo. 1997 and 1999,[link widoczny dla zalogowanych], salt iodine monitoring data comparison, the national iodized salt coverage in 1999 was 93.9, compared to 1997 increased by 4 percentage points; 1999 household salt iodine national pass rate of 80.6, than the 1997 Salt iodine pass rate increased by nearly 15 percentage points. 1999 national household salt iodine coefficient of variation was 50.6,[link widoczny dla zalogowanych], compared with 1997 decreased a lot, suggesting that most of iodized salt factory technology, quality awareness has improved significantly. But the more prominent issues in Hainan, iodine salt, actually increased the coefficient of variation of 34.4, up to 113.4. Although variation in Tibet is still more than 1O0, but has dropped 66.9, the trend is good, with a pass rate rose from 13.9 to 53.2%, which is the implementation of universal salt iodization in Tibet-based firm control measures confidence. In addition, Sichuan, Tianjin, iodized salt has a slight increase in the coefficient of variation, which should be relevant attention. 3 to discuss the characteristics of iodine deficiency disorders themselves determines the long-term prevention and control and continuity. Geography does not change, the disease will persist, in recent years, the National Iodine Deficiency Disorders prevention and control of the situation developed rapidly, through this several times to monitor, we can understand the level of 1999 national household qualified iodized salt has been over 1997 cases has greatly improved,[link widoczny dla zalogowanych], which is the joint efforts of relevant sectors of society the results obtained for future prevention and control has laid a good foundation. To achieve the goal of eliminating iodine deficiency, salt iodization in the implementation of this major control measures can never relax, even in some of iodine deficiency disorders has been basically controlled or controlled, as well. Control measures or short-term disruption to relax, can cause damage to generation. Although the household is being affected by the amount of iodine content of salt iodine content, iodine process, salt packaging, storage conditions, residents of the home,[link widoczny dla zalogowanych], and storage methods have private salt into the local market, and many other factors, but data indicate that potassium iodate iodine content of iodized salt was no significant difference in the circulation, stable iodine content of salt l5]. Household salt iodine content can be fully reflects the quality of iodized salt and iodized salt smuggling plant write-off status. The monitoring results through analysis, advice: ① should pay attention to the quality of iodization process; ② strengthen the legal management of iodized salt to eliminate the impact of non-iodized salt; ⑧ continue to strengthen the monitoring of iodized salt; ④ perfect quality assurance system; ⑤ strengthening health education and promotion work. (The data for the country's 31 provinces, municipalities and autonomous regions to provide, in this 31 units of the national administrative and business support to express my sincere thanks.) [
