2011年陕西省清涧县碘盐含量监测结果分析

目的及时掌握陕西省清涧县碘缺乏病区居民户碘盐普及情况、目标人群碘缺乏病防病知识知晓情况，动态评价人群碘营养状况及病情消长趋势，为本县科学调整干预策略提供科学依据。方法按照陕西省碘缺乏病监测方案的要求，2011年随机抽取我县9个乡（镇、街道办）36个行政村，开展居民食用盐调查，对抽取乡镇随机抽查了5所乡镇中心小学，每一个中心小学随机抽查8～10周岁学生42人，采用地方性甲状腺诊断标准（WS276-2007）检查甲状腺；在农村、城区各抽查了8～10岁学生各60名，共计120名学生，采集即时尿样5mL送上级实验室检测；对五年级学生和育龄妇女开展碘缺乏病健康教育问卷调查。结果共监测居民食用盐288份，合格碘盐282份，不合格碘盐6份，碘盐覆盖率100％；碘盐合格率97．92％；合格碘盐食用率97．92％，碘含量最高值50．10mg／kg，最低值14．61mg／kg。8～10岁学生农村城区尿样结果：农村8～10岁学生尿碘在138．56～411．23μg／L范围内；城区8～10岁学生尿碘在135．19-441．17μg／L范围内。五年级学生和育龄妇女（18-40岁）分别调查90名和45名，知晓率分别为65．56％和68．15％。结论我县碘盐覆盖率、合格率、食用率和甲肿率均达标。但碘缺乏病的防治任务还很艰巨，今后要加大病区碘盐的配备，加强碘缺乏病的健康教育工作，巩固碘缺乏病防治效果。

Analysis of the 2011 monitoring results of iodine deficiency disorder in Qingjian County, Shaanxi Province

Objective To conduct a timely investigation about the iodized salt coverage, the iodine deficiency disorder prevention knowledge of the target population in Qingjian County, Shaanxi Province and make a dynamic e-valuation of the iodine nutrient and trend of the disease so as to provide a scientific reference for the intervention strategy. Methods With reference to Shaanxi Provincial Scheme for the iodine deficiency disorder surveillance, in 2011, 36 administrative villages from 9 towns were randomly selected to investigate about the residents＇ salt intake; 42 pupils aged between 8-10, were randomly selected from 5 center primary schools in the sampled towns, with their thyroid tested in accordance to endemic thyroid diagnosis criteria WS276-2007;120 students, 60 urban and 60 rural were sampled to collect their urine 5 mL to be tested in the laboratory; students in grade five and women of child-bearing age were surveyed by health education questionnaire. Results 288 shares of edible salt were tested, 282 qualified and 6 shares unqualified, with the iodized salt coverage rate 100%, percent of pass 97.92%, qualified edible salt 97.92%. The maximum amount of iodine is 50.10 mg/kg and the minimum is 14.61 mg/kg. The urine test of the students at the age of 8 to 10 shows： the rural students＇ urine iodine is within 138.56-411.23 μg/L; the urban students＇ urine iodine is within 135.19-441.17 μg/L. The informed rate of iodine knowledge for pupils in grade five and women of child-bearing age （18-40 years old） is respectively 65.56% and 68.15%. Conclusion The iodized salt coverage, iodized salt consumption rate and TGR （total goiter rate） have all achieved the standard. But the prevention and health education about iodine deficiency disorder still need to be strengthened in order to consoli-date the effects of iodine deficiency disorder.
