目的评价新疆南部碘缺乏病地区重点人群碘营养水平,防止新生儿克汀病和儿童智力残疾的发生制定科学防控措施提供依据。方法按照国家《碘缺乏病监测方案》要求开展重点人群碘营养水平的评价。结果高危重点地区合格碘盐食用率95.02%,碘盐覆盖率92.87%,8~10岁儿童尿碘中位数为195.2μg/L、B超法检测8~10岁儿童甲状腺肿大率2.47%;育龄期妇女尿碘水平孕妇为175.20μg/L、哺乳期妇女为189.40μg/L,尿碘均值低于50μg/L、20μg/L的比例分别为10.02%和3.06%。结论实施应急补碘和免费发放碘盐后,重点人群碘营养水平得到显著改善,碘营养水平已经基本达到国家基本消除标准。
Objective To evaluate the level of iodine nutrition in key population of iodine deficiency disorders in southern Xinjiang, and to provide evidences for the prevention and control of neonatal cretinism and mental disability in children. Methods According to the national “Iodine Deficiency Disease Surveillance Program” to carry out evaluation of iodine levels in key populations. Results The prevalence of qualified iodized salt was 95.02%, the coverage of iodized salt was 92.87%, the median urinary iodine was 195.2μg / L in children aged 8-10 years, and the rate of goiter in children aged 8-10 years was 2.47% The pregnant women of childbearing age had the urinary iodine level of 175.20μg / L, the lactating women of 189.40μg / L, urinary iodine average value less than 50μg / L, and the ratio of 20μg / L were 10.02% and 3.06% respectively. Conclusion The iodine nutrition of key population has been significantly improved after emergency iodization and iodized salt have been released. The level of iodine nutrition has basically reached the national basic elimination standard.
