摘　　要：目的了解江西省南昌市8-10岁学龄儿童尿碘水平，为碘缺乏病防治工作提供理论依据。方法2009—2012年，在南昌市选取东湖区、西湖区、青山湖区、青云谱区、湾里区、南昌县、新建县、进贤县和安义县9个县（区）作为监测地区，每个县（区）按东、西、南、北、中5个方位各抽取1个乡（镇、街道），每个乡（镇、街道）抽取1所小学，每所小学抽取20名8-10岁儿童（男、女各半）作为调查对象，采集尿样，采用过硫酸铵消化-砷铈催化分光光度测定方法（WS／T107．2006）进行尿碘检测，整理尿碘数据，对结果进行统计分析。结果2009—2012年，共采集8-10岁学龄儿童尿样3600份，尿碘中位数为257．35μg／L。其中各年间尿碘中位数分别为315．30、314．80、262．92、112．73μg／L，尿碘中位数逐年下降，各年间比较差异有统计学意义（χ2=631．129，P〈0．05）。与2009、2010年比较，2011、2012年儿童尿碘中位数为100-199μg／L（碘适量）所占比率[15．22％（137／900）、14．67％（132／900）、25．11％（226／900）、30．22％（272／900）]逐年升高，4年间比较差异有统计学意义（χ2=93．977，P〈0．05）。以县（区）为单位，9个县（区）8-10岁学龄儿童尿碘中位数比较，差异有统计学意义（χ2=36．520，P〈0．05）。8、9、10岁学龄儿童尿碘中位数（280．10、255．11、249．20μg／L）随年龄增大而降低，年龄间比较差异有统计学意义（χ2=7．813，P〈0．05）。男性儿童尿碘中位数（269．70μg／L）高于女性儿童（247．60μg／L），性别间比较差异有统计学意义（Z=-3．704，P〈0．01）。结论南昌市8。10岁学龄儿童碘营养状况良好，碘摄入量满足机体需求，建议加强学龄儿童尿碘监测．预防碘摄入不足或碘过量可能带来的隐患。Objective To survey the urinary iodine （UI） status of school children aged from 8 to 10 in Nanehang City, and to provide a scientific basis for preventing and controlling the iodine deficiency disorders （IDD）. Methods From 2009 to 2012, Donghu, Xihn, Qingshanhu, Qingyunpu, Wanli, Nanchang, Xinjian, Jinxian and Anyi 9 counties （areas） were chosen in Nanchang City as monitoring areas, and five townships were selected according to the five directions as east, west, south, north and centre in each county （area）, one school was selected in each township, 20 school children aged from 8 to 10 （10 males and 10 females） were chosen as respondents. Ammonium persulfate digestion-arsenic cerium catalytic speetrophotometry （WS/F 107-2006） was used to detect UI. The monitoring data on UI of 8 to 10 years old school-age children were collected and analyzed. Results From 2009 to 2012, a total of 3 600 urine samples were collected, the median of urinary iodine （MUI） was 257.35 μg/L. In the 4 years, the MUI of school children aged from 8 to 10 was 315.30, 314.80, 262.92 and 112.73 μg/L, respectively, the MUI decreased year by year, the difference was statistically significant （χ2 = 631.129, P 〈 0.05）. Compared with 2009 and 2010, the proportion [15.22% （137/900）, 14.67% （132/900）, 25.11% （226/900）, 30.22%（272/900）] of MUI of 100 - 199 μg/L （moderate intake）in 2011 and 2012 increased year by year; the difference was statistically significant （χ2 = 93.977, P 〈 0.05）. The MUIs between different counties （areas） were statistically significant （χ2 = 36.520, P 〈 0.05）. The MUI of children aged 8 （280.10 μg/L）, 9 （255.11 μg/L） and 10 （249.20 μg/L） decreased with increasingage （χ2 = 7.813, P 〈 0.05）. The MUI of male students （269.70 μg/L） was higher than that of female students （247.60 μg/L）, the difference was statistically significant （Z = - 3.704, P 〈 0.01）. Conclusions Iodine nutrition status of 8 to 10 years old school-ag
