了解兰州市农村8~10岁儿童碘营养状况,指导农村居民科学补碘。2013-2015年,按照全国碘缺乏病监测方案,在兰州市西固区、红古区、永登县各随机抽取1所小学,每所小学随机抽取8~10岁学生为研究对象,共440例。采用砷铈催化分光光度法进行尿碘检测。结果显示,2013-2015年,440例儿童尿碘中位数分别为233.3μg/L,169.6μg/L,143.8μg/L,逐年降低,差异有统计学意义(χ~2=42.423,P<0.05)。尿碘含量<100μg/L者89例(20.23%)、100~μg/L者160例(36.36%)、200~μg/L者123例(27.96%)、≥300μg/L者68例(15.45%)。男性儿童尿碘中位数178.9μg/L,女性儿童尿碘中位数182.1μg/L,性别间差异无统计学意义(Z=-1.414,P>0.05)。三区县中,红古区尿碘含量100~μg/L 45例(29.03%);200~μg/L 36例(23.23%);≥300μg/L 39例(25.16%),不同尿碘含量在三区县比较差异均有统计学意义(χ~2=6.899、5.465、17.900,P<0.05)。兰州市居民碘营养总体处于适宜水平,但碘缺乏有上升趋势,碘过量问题也存在,且分布区域不平衡。
To understand the nutritional status of iodine in children aged 8 to 10 years in rural areas of Lanzhou City, to guide rural residents in scientific iodization. In 2013-2015, 1 primary school was randomly selected in each of Xigu District, Honggu District and Yongdeng County in Lanzhou City, according to the national monitoring program for iodine deficiency disorders. Students of 8 to 10 years old were randomly selected from each primary school for a total of 440 example. Arsenic and cerium catalytic spectrophotometry urine iodine detection. The results showed that from 2013 to 2015, the urinary iodine median of 440 children was 233.3μg / L, 169.6μg / L and 143.8μg / L, respectively, which decreased year by year with a significant difference (χ ~ 2 = 42.423, P < 0.05). There were 89 cases (20.23%) with urinary iodine <100μg / L, 160 cases (36.36%) with 100μg / L, 123 cases (27.96%) with 200μg / L and 68 cases %). The median urinary iodine of male children was 178.9 μg / L, while the median urinary iodine of female children was 182.1 μg / L. The difference was not statistically significant (Z = -1.414, P> 0.05). In the three districts and counties, there were 45 cases (29.03%) of urinary iodine in 100 ~ μg / L and 36 cases (23.23%) in 200 ~ μg / L and 39 cases In the three districts and counties, the differences were statistically significant (χ ~ 2 = 6.899,5.465,17.900, P <0.05). Lanzhou residents overall iodine nutrition at the appropriate level, but the iodine deficiency has an upward trend, the problem of excessive iodine also exists, and the distribution of regional imbalance.
