摘要
目的了解甘肃省甘南藏族自治卅l农区和牧区人群的碘营养水平，为碘缺乏病防治提供依据。方法2011年5月，在甘肃省甘南藏族自治州合作市卡加曼乡（农区）和佐盖多玛乡（牧区），采集当地不同类型饮用水检测水碘，并抽取育龄妇女、孕妇、哺乳期妇女各30人，同时选取这些妇女所在家庭中20～50岁的成年男性90人（每家1人）和当地学校8～10岁儿童90人（每个年龄组30人），检测随意1次性尿碘。从上述三类妇女中各抽取10人，回顾家庭24h内所摄入的食物（不包括调味品）种类，采集家庭食用盐和主要食物，检测盐碘和食物含碘量。采用砷铈氧化还原法（GB／T5750．1—2006）检测水碘；过硫酸铵消化一砷铈催化分光光度方法（WS／T107—2006）检测尿碘；直接测定法（GB／T13025．7—1999）检测盐碘；碱灰化砷铈接触比色法检测食物碘。结果农区和牧区各抽取饮用水样10份，水碘分别为（1．634±0．14）、（2．08±1．90）IXg／L。农区和牧区育龄妇女、孕妇、哺乳期妇女、成年男性和8—10岁儿童的尿碘中位数分别为141．99、126．65、253．33、258．07、193．01和137．26、97．36、126．16、159．48、285．07μg／L；农区和牧区哺乳期妇女、成年男性和8～10岁儿童尿碘水平比较，差异有统计学意义（Z值分别为-2．421、-6．915、-3．848，P均〈0．05）。除牧区哺乳期妇女和孕妇外，其他各类人群尿碘〈50μg／L的比例均〈20％，尿碘〈100μg／L的比例均〈50％。农区和牧区的碘盐覆盖率分别为100％（30／30）和90％（27／30），盐碘分别为（32．14-7．8）、（32．3±6．0）mg／kg。农区主要食物为自产的洋芋、青稞面和白菜等，膳食含碘量平均为285．7μg／kg；牧区主要食物为炒面、白面、酥油、酸奶和青稞等，膳食含碘量平均为51．1μg／kg。结论在目前盐碘浓度下，低水碘的藏
Objective To study the iodine nutritional status of population living in Tibetan pastoral areas, in order to provide a scientific basis for prevention and control of iodine deficiency disorders. Methods Drinking water samples were collected to test iodine content in agricuhural town（Kajiaman） and pastoral area（Zuogaiduoma town） of Hezuo in Gannan Tibetan autonomous prefecture. Thirty of child-bearing age, pregnant and breasffeeding women were selected, respectively, and 90 male adults aged 20 - 50 from these families（ 1 from each family） and 90 children aged 8 - 10 （30 people in each age group） from local schools were randomly sampled at the same time, and urinary iodine （UI） was measured randomly. Edible salt and main food samples were collected to test iodine content from the 10 families of the three types of women, respectively, and they were asked to recall its family intake of food species in the past 24 h excluding spices. The water iodine was determined using arsenic-cerium redox method （GB/T 5750.1-2006 ） ; UI with ammonium persulfate digestion-arsenic cerium catalytic speetrophotometric method （WS/T 107-2006）; salt iodine used direct determination method（GB/T 13025.7-1999）; and food iodine with alkali the gray arsenic cerium contact colorimetry. All these work were done in May,2011. Results The average of water iodine was （1.63 ± 0.14）μg/L in agricultural areas and （2.08 ±l.90）μg/L in pastoral areas of the 10 water samples tested, respectively. The median urinary iodine （MUI） among women of pregnant, lactating and child-bearing age, mate adults and children was 141.99, 126.65, 253.33, 258.07, 191.0 μg/L, respectively, in agricultural areas and 137.26, 97.36, 126.16, 159.48, 285.07μg/L, respectively, in pastoral areas. The difference of MUI in lactating, male adults and children between pastoral and agricultural areas was statistically significant. The proportion of UI 〈 50 μg/L was less than 20%, and 〈 100 μg/L was less than 50% among all population
