目的通过对新疆南部地区育龄期妇女为期4年的尿碘水平动态观察,以掌握目标人群的碘营养水平,为制定口服碘化油补碘措施奠定基础。方法按照国家《碘缺乏病监测方案》和“十一五”科技支撑计划资助项目《碘缺乏病防治技术应用研究》课题设计书进行采样。调查周期分4年进行,时间为2006年、2007年、2009年和2011年。结果 4年共监测食盐6 980份,碘盐覆盖率为92.36%,合格碘盐食用率为94.05%。检测育龄期妇女尿样2 700份,尿碘中位数分别为98.6μg/L、88.22μg/L、300.45μg/L和182.32μg/L。结论新疆南部地区育龄期妇女碘营养水平已基本达到国家标准,低于100.00μg/L的占10%,相关部门尚需进一步加大碘盐监测力度,改善人群缺碘状况。
Objective To observe the urinary iodine level of 4-year-old women of childbearing age in the southern part of Xinjiang to understand the iodine nutrition level of the target population and lay a foundation for the development of iodine-supplemented iodine supplementation. Methods Sampling was conducted according to the design of the subject of “Study on the Application of Preventing and Controlling Iodine Deficiency Disorders” funded by the National “Iodine Deficiency Disorders Surveillance Program” and the “Eleventh Five-year” Scientific and Technological Support Program. The investigation cycle is conducted in four years, with the dates of 2006, 2007, 2009 and 2011. Results A total of 6 980 salt samples were monitored during the four years. The iodized salt coverage was 92.36%. The acceptable iodine salt consumption rate was 94.05%. A total of 2 700 urinary samples were collected from women of childbearing age. The urinary iodine median was 98.6 μg / L, 88.22 μg / L, 300.45 μg / L and 182.32 μg / L, respectively. Conclusion Iodine nutritional status of women of childbearing age in southern Xinjiang has basically reached the national standard, with the proportion below 100.00μg / L accounting for 10%. The relevant departments still need to further increase iodine salt monitoring and improve iodine deficiency status in the population.
