摘要
目的了解四川省眉山市仁寿县重点人群家庭食用盐碘水平和碘营养状况,为完善可持续消除碘缺乏病工作机制提供依据。方法2018—2022年在仁寿县按东、西、南、北、中划分5个抽样片区,每年随机抽取每个片区1个乡镇或街道,在抽取的每个乡镇或街道中随机抽取1所小学,每所小学抽取8~10岁非寄宿制学生40名,在抽取的5个乡镇或街道中随机抽取20名孕妇,采集儿童和孕妇尿样和家中食用盐样,检测尿碘和盐碘含量。采用SPSS 26.0软件进行统计分析,利用中位数M和四分位数间距(P25,P75)描述偏态计量资料,采用Kruskal-Wallis H检验比较组间差异,χ^(2)检验比较构成比及率的差异,检验水准α=0.05。结果2018—2022年采集8~10岁儿童尿样和家中食用盐样各1000份;采集孕妇尿样和家中食用盐样各500份,共计1500份。采集的盐样碘盐覆盖率为100.00%,碘盐合格率为99.80%,合格碘盐使用率为99.80%。2018—2022各年份儿童尿碘中位数分别为182.10μg/L、171.00μg/L、237.10μg/L、250.50μg/L和200.96μg/L,孕妇尿碘中位数分别为109.15μg/L、101.00μg/L、140.35μg/L、244.50μg/L和121.92μg/L。结论仁寿县碘盐普及程度较好,儿童碘营养维持在较好水平,但孕妇依然存在碘缺乏风险。未来应该重点完善可持续消除碘缺乏病工作机制,开展有针对性的碘缺乏病健康教育,有助于提高居民碘缺乏病防治意识。
Objective To understand the iodine level and iodine nutrition of key population in Renshou District,and to provide basis for improving the working mechanism of sustainable elimination of iodine deficiency disorders.Methods From 2018 to 2022,Renshou District was divided into five sampling areas according to the east,west,south,north and middle,and one township or stree was randomly selected from each area every year.One primary school was randomly selected from each town or street,40 non-boarding students aged eight to ten were randomly selected from each primary school,and 20 pregnant women were randomly selected from five towns or streets.Sal and urine samples were collected from children's and pregnant women's households and tested for salt iodine and urine iodine content.SPSS 26.0 software was used for statistical analysis.Median(M)and interquartile distance(P_(25),P_(75))were used to describe the skewness of measurement data Kruskal-Wallis H test was used to compare the differences between groups,andχ^(2)test was used to compare the differences in composition ratio and rate.Results From 2018 to 2022,a total of 1000urine samples and home salt samples were collected from children aged eight to ten,and 500 urine samples and home salt samples were collected from pregnant women of 1500 samples.The iodized salt coverage rate was 100.00%,the qualified rate of iodized salt was 99.80%,and the consumption rate of qualified iodized salt was 99.80%.The median urinary iodine levels in children were 182.10μg/L,171.00μg/L,237.10μg/L,250.50μg/L and 200.96μg/L,respectively.The median urinary iodine levels in pregnant women were 109.15μg/L,101.00μg/L,140.35μg/L,244.50μg/L and 121.92μg/L,respectively.Conclusions Renshou County is in a state of continuous elimination of iodine deficiency diseases.The popularization of iodized salt is relatively good,and children′s iodine nutrition is maintained at a good level,but pregant women still face the risk of iodine deficiency.In future,it should be focused on improving the
