摘要
目的本研究旨在调查鄂尔多斯市2024年8~10岁学龄儿童碘营养水平,为科学开展重点人群的碘补充工作提供依据。方法依照《全国碘缺乏病监测方案(2016版)》的要求开展抽样调查,分别检测食盐中的碘含量、学龄儿童尿碘水平,并评估其甲状腺肿大发生情况。采用百分比及中位数描述盐碘和尿碘水平,尿碘中位数的组间比较采用Mann-Whitney U检验和Kruskal-Wallis H检验,构成比和率之间的差异采用χ^(2)检验。结果2024年鄂尔多斯市8~10岁儿童总碘盐覆盖率为98.16%,碘盐合格率达到97.96%,合格碘盐食用率为96.16%。尿碘中位数为200.80μg/L,其中68.83%的儿童尿碘浓度处于100~299μg/L的适宜范围。在分地区比较中,不同城区儿童尿碘水平差异具有统计学意义(χ^(2)=13.953,P=0.030);分年龄段分析显示,8~10岁儿童间尿碘水平差异亦有统计学意义(χ^(2)=16.329,P=0.012)。全市儿童甲状腺容积中位数为2.87 m L,甲状腺肿大率为2.33%。不同年龄组(H=44.631,P<0.001)及不同地区(H=7.897,P=0.019)儿童的甲状腺容积差异均具有统计学意义。结论鄂尔多斯市学龄儿童的碘营养总体处于适宜水平。但地区间和年龄段间存在一定差异,建议持续关注重点地区和特定年龄段儿童的碘营养状况,实施差异化干预策略,以保障儿童碘营养均衡和甲状腺健康。
Objective This study aims to investigate the iodine nutritional status of children aged 8 to 10 in Ordos City in 2024,provide a basis for scientifically conducting iodine supplementation work for key populations.Methods Sampling surveys were conducted in accordance with the requirements of the"National Iodine Deficiency Disorders Surveillance Plan(2016 Edition)".The iodine content in salt and the urinary iodine levels of school-aged children were detected,and the occurrence of goiter was evaluated.Percentages and medians were used to describe the iodine levels in salt and urine.The Mann-Whitney U test and Kruskal-Wallis H test were used for the comparison of median urinary iodine levels between groups,and the X2 test was used to compare the differences in proportions and rates.Results In 2024,the total coverage rate of iodized salt among children aged 8 to 10 in Ordos City was 98.16%,the qualification rate of iodizedsalt was 97.96%,and the consumption rate of qualified iodized salt was 96.16%.The median urinary iodine level was 200.80μg/L,and 68.83%of the children had urinary iodine concentrations within the appropriate range of 100 to 299μg/L.In the comparison between different regions,the differences in urinary iodine levels among children in different urban areas were statistically significant(χ^(2)=13.953,P=0.030).The analysis by age group showed that the differences in urinary iodine levels among children aged 8 to 10 were also significant(χ^(2)=16.329,P=0.012).The median thyroid volume of children in the city was 2.87 mL,and the goiter rate was 2.33%.The differences in thyroid volume among children of different age groups(H=44.631,P<0.01)and different regions(H=7.897,P=0.019)were statistically significant.Conclusion The iodine nutritional status of school-aged children in Ordos City is generally appropriate.However,there are certain differences between regions and age groups.It is recommended to continuously monitor the iodine nutritional status of children in key regions and specific age groups,and implement differentiated intervention strategies to ensure balanced iodine nutrition and thyroid health in children.
