摘要
目的评价合作市藏族人群的碘营养状况,为藏族地区碘缺乏病提供依据。方法随机抽取未孕育龄妇女(18～40岁)、孕妇、哺乳期妇女、8～10岁学龄儿童(男女各半)及20～50岁成年男性,采集随机一次性尿样,用过硫酸铵消化—砷铈催化分光光度方法(WS/T107-2006)测定尿碘。结果合作市未孕育龄妇女、孕妇、哺乳期妇女、8～10岁学龄儿童及成年男性的尿碘中位数分别为138.75 μg/L、155.34 μg/L、211.92 μg/L、184.12 μg/L和232.50 μg/L,尿碘<50 μg/L的比例均<20%,<100 μg/L的比例<50%,学生尿碘中位数与其他组有显著性差异(P<0.01)。育龄妇女、成年男性和学龄儿童在100～200 μg/L适宜范围的比例分别53.0%、45.6%和27.5%,孕妇和哺乳期妇女尿碘在150～250 μg/L适宜范围的比例分别为34.5%和33.7%,<150 μg/L的比例分别为46.5%和35.9%。结论 5种重点人群的尿碘中位数都达到了相应的推荐标准,但尿碘在适宜范围内的比例在30%～50%之间,育龄妇女仍然是碘缺乏病最需要关注的人群。藏族地区碘缺乏病防治工作应结合不同地区(农区或牧区)、不同生活方式和不同重点人群及其膳食等情况,有针对性地科学补碘,才能使藏族地区人群的碘营养状况达到平衡。
OBJECTIVE To evaluate the iodine nutrition status of Tibetan populations in Hezuo City of Gansu Province in 2010. METHODS The unpregnancy women, pregnant women, lactating women, 8-10 years children and adult male were selected randomly from two towns. The urinary iodine（UI）were determined by As3＋-Ce4＋ catalytic spectrophotometry（WS/T 107-2006）.RESULTS The median urine iodine （MUI） among unpregnancy women, pregnant women, lactating women, 8-10 years children and adult male were 138.75μg/L, 155.34 μg/L, 211.92μg/L, 184.12 μg/L and 232.50 μg/L respectively, the percentage of UI lower than 50μg/L among the population was all less than 20%, and lower than 100 μg/L all less than 50%. The UI proportion between 100μg/L and 200 μg/L were 53.0%,44.6% and 27.5% among un-pregnancy women, and adult male and 8-10 years children, which betweenl50 μg/L and 250 μg/L were 34.4% and 33.7%, less than the 150μg/L were 46.5% and 35.9% among pregnant women and lactating women. CONCLUSIONS The urine iodine level was up to the reference value recommended, but UI proportion of a appropriate range was 30- 50%, childbearing age women was vulnerable population of iodine deficiency disease. It should be combined with different area（rural or pastoral）, a different life ways, different target groups and dietary conditions et al to make scientific iodine supplementation for iodine nutrition balance of Tibetan population in Tibetan areas.
