目的调查及评价东营市儿童及孕期哺乳期妇女碘营养状况,为制定食盐加碘标准提供科学依据。方法采用2011年全国碘缺乏病监测东营市8岁~10岁儿童及孕乳期妇女尿碘数据,描述其频数分布,进行统计学分析。结果8岁~10岁儿童总体尿碘中位数为248.4μg/L;广饶县儿童尿碘中位数高于适宜量(多组独立样本秩和检验,P<0.05,CI=90%,α=0.1);Mann-Whitney test进行两两秩和检验显示,广饶县尿碘水较高(P<0.01);河口区和垦利县的儿童尿碘水平不同(P=0.037)。其余各县区间儿童尿碘水平均差异无统计学意义(P>0.2);两区孕乳期女总体尿碘中位数分布差异无统计学意义(孕妇P=0.279,哺乳期妇女P=0.598)。结论根据碘营养状况判断原则,东营市儿童碘营养略有偏高,孕乳期妇女的碘营养略低,但均可接受。推断现行碘盐标准略高,需适当降低,提倡孕乳期妇女通过膳食补碘。
Objective To investigate and evaluate the iodine nutrition status of children in Dongying city and breast-feeding women in pregnancy, and to provide a scientific basis for the establishment of salt iodine standard. Methods Urine iodine data of children aged 8 to 10 years and pregnant women in Dongying city were monitored by iodine deficiency disorders in 2011. Their frequency distributions were described and statistically analyzed. Results The median urinary iodine was 248.4 μg / L in children aged 8 to 10 years. The median urinary iodine in children in Guangrao County was higher than that in the appropriate group (rank sum test with multiple independent samples, P <0.05, CI = 90%, α = 0.1). Mann-Whitney test showed that urine iodine water was higher in Guangrao County (P <0.01). Children in Urumqi District and Kenli County had different urine iodine levels (P = 0.037). There was no significant difference in urinary iodine levels among children in other counties (P> 0.2). There was no significant difference in urinary iodine median distribution among pregnant women in both regions (P = 0.279, P = 0.598 ). Conclusion According to the principle of iodine nutrition judgment, iodine nutrition of children in Dongying City is slightly higher than that of iodine nutrition in pregnant women, but it is acceptable. It is inferred that the current iodized salt standard is slightly higher, which needs to be reduced appropriately to promote pregnant women to supplement iodine through diet.
