目的实施尿碘监测,为系统了解评价康定县居民碘营养状况提供依据。方法 2008-2010年按地理位置随机抽取8个乡镇,分年对其中5个乡(镇)孕妇、哺乳期妇女、0～2岁婴幼儿分别随机抽取各10名,总计150份尿样,3年共抽取450份、8～10岁学龄儿童50名尿液(男女各半),3年共抽取150份。尿碘检测采用过硫酸铵消化—砷铈催化分光光度法(WS/T107-2006)。结果 2008-2010年,孕妇、哺乳期妇女、0～2岁婴幼儿、8～10岁学龄儿童4类人群尿碘中位数年均分别为187.98μg/L、168.3μg/L、221.2μg/L和231.13μg/L,其中>100μg/L者分别占均总检数的92.67%、85.33%、79.33%和89.33%。结论康定县居民碘营养水平总体上处于适宜水平,今后应关注儿童、哺乳期妇女等人群的碘营养状况,强化控制措施,为持续巩固消除碘缺乏病成果而努力。
Objective To implement urinary iodine monitoring to provide a basis for systematic understanding of iodine nutrition status of residents in Kangding County. Methods From 2008 to 2010, 8 villages and towns were randomly selected according to their geographical locations. Ten pregnant women, lactating women and 0 to 2-year-old infants were randomly selected from 10 townships (towns), 150 urine samples During the year, 450 urine samples were collected from 50 school-aged children aged 8-10 years (half male and half female). A total of 150 urine samples were collected in 3 years. Urinary iodine detection using ammonium persulfate digestion - arsenic cerium catalytic spectrophotometry (WS / T107-2006). Results The median urinary iodine of pregnant women, lactating women, 0 ~ 2 years old children and 8 ~ 10 years old school children from 2008 to 2010 were 187.98μg / L, 168.3μg / L, 221.2μg / L, L and 231.13μg / L, respectively, with> 100μg / L accounting for 92.67%, 85.33%, 79.33% and 89.33% of the total. Conclusion The iodine nutrition of residents in Kangding County is generally at an appropriate level. In the future, iodine nutrition status among children, lactating women and other populations should be taken into consideration. Measures should be taken to strengthen control measures so as to continue consolidating and eliminating iodine deficiency disorders.
