摘要
目的了解盐碘含量调整后内蒙古呼和浩特市重点人群碘营养状况。方法2013年，在呼和浩特市9个旗县区中抽取4个旗县区，每个旗县区按东、西、南、北、中划分为5个抽样片区，每个片区抽取1个乡镇或街道办事处，每个乡镇或街道办事处在常住人口中抽取8—10岁学龄儿童、18-49岁育龄妇女、哺乳妇女及其O-2岁婴幼儿各10人，采集即时尿样，检测尿碘。另外，在呼和浩特市9个旗县区内各抽取1所医院，每所医院抽取50名孕妇，根据孕期分组，采集即时尿样，检测尿碘。尿碘检测采用硫酸铵消化．砷铈接触法。结果共采集8-10岁学龄儿童、育龄妇女、哺乳妇女、0—2岁婴幼儿尿样212、213、201、208份，尿碘中位数分别为150．8、112．9、151．0、140．6μg／L。184对配对哺乳妇女与其婴幼儿的尿碘水平具有统计学相关性[相关系数（r）=0．352，P〈0．01]。共采集孕妇尿样461份，尿碘中位数为154．8μg／L，尿碘〈150μg／L的比例为48．6％（224／461）。孕早、中、晚期尿碘中位数分别为155．0、158．0、150．2μg／L，尿碘〈150μg／L的比例分别是50．0％（33／66）、47．2％（50／106）、49．8％（144／289），三者比较差异无统计学意义（x2=10．671，P〉0．05）。结论盐碘含量调整后呼和浩特市重点人群碘营养处于适宜水平。
Objective To investigate the iodine nutrition level and health condition of key population in Hohhot after adjustment of iodized salt standard. Methods Using random sampling method, 4 districts among the 9 districts of Hohhot were investigated randomly, a town in east, west, south, north and center part was selected, and then children aged 8 to 10, fertile women aged 18 to 49, lactating women and infants less than 24 months old each at least 10 people, were randomly selected. Nine investigation hospitals were randomly selected from 9 districts in Hohhot. At least 50 pregnant women in different gestation period were selected as subjects in each hospital, their urine samples were collected. Four hundred and sixty-one urine samples were collected totally. All the urine samples were detected by acid digestion arsenic-cerium contact method. Results The median of urinary iodine in 212 school-age children, 213 fertile women, 201 lactating women, and 208 infants was 150.8, 112.9, 151.0 and 140.6 μg/L, respectively. In 184 pair of lactating women and their infants, the level of urine iodine in infants rose with increasing of urine iodine in lactating women [correlation coefficient （r） = 0：352, P 〈 0.01]. The median of urinary iodine was 154.8 μg/L in 461 pregnant women. The ratio of urinary iodine less than 150 μg/L was 48.6% （224/461）. The median of urinary iodine in the three trimester was 155.0, 158.0 and 150.2 μg/L, respectively, the ratio of urinary iodine less than 150μg/L in each trimester was 50.0% （33/66）, 47.2% （50/106） and 49.8% （144/289）, and the difference was not statistically significant （X2 = 10.671, P 〉 0.05）. Conclusion After adjustment of iodized saltstandard, iodine nutrition level is suitable for all the key population in Hohhot.
