摘　　要：目的了解铜川市重点人群碘营养状况,为防治碘缺乏病提供科学依据。方法在铜川市的4个区(县)按东、西、南、北、中划分5个抽样片区,在每个片区各随机抽取1个乡/镇/街道办事处(以下统称乡),每个乡各抽取1所小学校,每所小学抽取8~10岁学生42人,进行甲状腺触诊检测和尿样采集,并采集该学生家中食用盐样。在所抽取的5个乡中每乡抽取21名孕妇采集孕妇尿样和家中食用盐。尿碘检测采用《尿中碘的砷铈催化分光光度测定方法》(WS/T 107-2016),盐样检测采用直接滴定法或氧化还原法(GB/T 13025.7-2012),甲状腺检测采用触诊法。结果 2017年全市共检测居民食用盐1 308份,盐碘中位数是23.2 mg/kg,碘盐覆盖率与合格碘盐食用率分别是99.16%(1 297/1 308)和96.79%(1 266/1 308)。全市共852名学生检测了甲状腺和尿碘,甲状腺肿大率是2.35%(20/852),尿碘中位数是215.08μg/L,尿碘范围是2.03~895.84μg/L,尿碘浓度50μg/L以下比例是4.3%(37/852),在50~99μg/L占比是10.3%(88/852),100~199μg/L比例是29.2%(249/852),200~299μg/L和300μg/L以上的比例分别是30.8%(262/852)和25.4%(216/852)。其中男生437份,尿碘中位数是223.85μg/L;女生415份,中位数为205.58μg/L。各地区男生尿碘中位数经K-W检验差异有统计学意义(H=36.781,P<0.05),各区县女生尿碘中位数经检验差异无统计学意义(H=3.741,P=0.291)。各区县学龄儿童尿碘水平比较差异有统计学意义(H=28.204,P<0.05)。全市共检测了456份孕妇尿碘,尿碘中位数是179.50μg/L,尿碘范围是6.11~889.44μg/L,孕妇尿碘100μg/L以下和100~149μg/L的比例分别是22.6%(103/456)和19.5%(89/456),150~249μg/L占比是27.9%(127/456),250~499μg/L的比例是24.6%(112/456)。各区县间孕妇尿碘中位数经检验差异有统计学意义(H=8.767,P<0.05)。结论 2017年铜川市重点人群碘营养适宜,并持续达到国家消除碘缺乏病的标准。Objective To understand the iodine nutritional status of focus group in Tongchuan City,and to provide scientific basis for prevention and treatment of iodine deficiency disorders. Methods Each town was selected respectively from 5 areas（ the east,west,south,north and center） in 4 counties of the city. One primary school was selected in each town,there were 42 children aged 8-10 years old in every school were selected for thyroid palpation and urine samples,their residential edible salt were also sampled. A total of 21 pregnant women were selected in each town to collect urine samples and residential edible salt. Urinary iodine was detected by using ＂Arsenic Cerium Catalytic Spectrophotometric＂（ WS/T 107-2016）. Salt samples were detected by direct titration or oxidation-reduction method（ GB/T 13 025. 7-2012）. Palpation was used for thyroid examination. Results Totally 1 308 residential edible salt samples were detected in 2017,the median of salt iodine content was 23. 2 mg/kg,iodized salt coverage rates and qualified iodized salt consumption rates were 99. 16%（ 1 297/1 308） and 96. 79%（ 1 266/1 308）,respectively. A total of 852 students were examined by the thyroid palpation and urine iodine,the rate of goiter was 2. 35%（ 20/852）, the median urinary iodine（ MUI） was 215. 08 μg/L,the range of urinary iodine was 2. 03 ~ 895. 84 μg/L,of which 437 boys,their MUI was 223. 85 μg/L; About 415 girls,their MUI was 205. 58 μg/L. The proportion of Urinary iodine concentration under 50μg/L was 4. 3%（37/852）,50 ~ 99 μg/L accounted for 10. 3%（88/852）,100~ 199 μg/L accounted for 29. 2%（249/852）,200 ~ 299 μg/L and more than 300 μg/L were 30. 8%（ 262/852） and 25. 4%（216/852）,respectively. In gender groups,the difference in the MUI among boys by K-W test was statistically significant（ H = 36. 781,P 〈0. 05）,the difference of MUI among girls was no statistically significant（ H = 3. 741,P = 0. 291）. The difference of urinary iodine level among 8 ~ 10 years old chil
