摘要
目的:分析阳山县重点人群(8~10岁儿童及孕妇)的碘营养状况,为制定有效的碘缺乏病预防策略提供科学依据。方法:将阳山县辖区划分为东、南、西、北、中5个片区,每个片区随机选取40名8~10岁儿童及20名孕妇作为监测对象,采集监测对象的尿液及其家中食用盐样本进行碘含量检测。结果:2022—2024年共检测食用盐900份,盐碘中位数为25.3 mg·kg^(-1),碘盐覆盖率为99.7%;合格碘盐食用率为98.1%,乡镇(98.8%)高于城区(95.6%)(Z=8.037,p<0.05);共检测8~10岁儿童尿样600份,尿碘中位数为197μg·L^(-1),不同年份尿碘中位数差异有统计学意义(H=23.009,p<0.05),城区(233μg·L^(-1))高于乡镇(185μg·L^(-1))(Z=3.608,p<0.05);共检测孕妇尿样300份,尿碘中位数为157μg·L^(-1),不同年份、城乡孕妇尿碘中位数差异无统计学意义(p>0.05)。结论:阳山县重点人群碘营养整体处于适宜水平,符合国家碘缺乏病消除标准,但碘营养不足和过量仍占相当比例。应结合实际,分类指导,持续做好重点人群碘营养知识普及工作,科学补碘,预防碘缺乏病。
Objective:To analyze the iodine nutrition status of key populations(children aged 8~10 years and pregnant women)in Yangshan,so as to provide scientific basis for formulating effective prevention strategies for IDD.Method:The Yangshan area was divided into 5 regions,namely the east,south,west,north,and central.In each region,40 children aged 8~10 years old and 20 pregnant women were randomly selected as monitoring subjects.Their urine samples and household edible salt samples were collected for iodine content testing.Result:A total of 900 samples of edible salt were tested from 2022 to 2024,with a median iodine content of 25.3 mg·kg^(-1)and an iodized salt coverage rate of 99.7%;the qualified iodized salt consumption rate was 98.1%,and the township(98.8%)was higher than that of urban areas(95.6%)(Z=8.037,p<0.05);a total of 600 urine samples from children aged 8 to 10 years were tested,and the median urinary iodine was 197μg·L^(-1).There was a significant difference in the median urinary iodine among different years(H=23.009,p<0.05),with urban areas(233μg·L^(-1))higher than rural areas(185μg·L^(-1))(Z=3.608,p<0.05);a total of 300 pregnant women’s urine samples were tested,and the median urinary iodine was 157μg·L^(-1).There was no significant difference in the median urinary iodine between pregnant women from different years or urban and rural areas(p>0.05).Conclusion:The overall iodine nutrition of key populations in Yangshan is at a suitable level,which meets the national standard for eliminating iodine deficiency disorders.However,there are still considerable proportions of insufficient and excessive iodine nutrition.We should combine with the actual situation,provide guidance by classification,continue to do a good job in popularizing iodine nutrition knowledge among key populations,and scientifically supplement iodine to prevent iodine deficiency disorders.
