目的了解西安市重点人群的碘营养现状,以评价现行的碘盐浓度能否满足不同重点人群的碘营养需要,了解学龄儿童的碘营养水平能否反映其他重点人群的碘营养状况,为制定防治策略提供科学依据。方法采用整群随机抽样法。随机选择西安市东、西、南、北、中5个不同方位的乡镇,学龄儿童、育龄妇女、孕妇、哺乳妇女及婴幼儿作为调查对象。监测这5种人群的碘营养现状。结果儿童甲状腺肿大率为4.29%,居民碘盐覆盖率为92.38%,合格碘盐食用率为90.95%,8~10岁学龄儿童、18~40岁育龄妇女、孕妇、哺乳期妇女和婴幼儿的尿碘中位数分别为383μg/L、305.5μg/L、222μg/L、230.5μg/L、230μg/L。外环境水碘中位数为2μg/L。结论西安市重点人群的碘营养水平达到或超过WHO制定的碘适宜水平,达到国家消除碘缺乏病标准的要求,西安市居民的盐碘浓度有下调的空间。建议将孕妇尿碘监测列入常规监测内容。
Objective To understand the status quo of iodine nutrition in key population of Xi’an to evaluate whether the current iodized salt concentration can meet the needs of iodine nutrition of different key populations and to understand whether iodine nutrition of school-age children reflects the iodine nutrition status of other key populations, Strategy to provide a scientific basis. Methods A cluster random sampling method was used. Randomly selected 5 townships, school-age children, women of childbearing age, pregnant women, lactating women and infants in 5 different orientations in east, west, south, north and west of Xi’an as the survey subjects. Monitor the status of iodine nutrition in these 5 populations. Results The rate of thyroid goiter in children was 4.29%, the rate of iodized salt in residents was 92.38%, the rate of qualified iodized salt was 90.95%, school children aged 8-10, women of reproductive age 18-40, pregnant women, lactating women and infants The urinary iodine median was 383μg / L, 305.5μg / L, 222μg / L, 230.5μg / L, 230μg / L respectively. Water environment, the median iodine 2μg / L. Conclusion The iodine nutrition of key population in Xi’an meets or exceeds the appropriate level of iodine prescribed by the WHO, meeting the requirements of the state to eliminate the standard of iodine deficiency disorders. The salt iodine concentration of Xi’an residents has room for downward adjustment. It is recommended to monitor urinary iodine in pregnant women included in the routine monitoring.
