上海市虹口区居民碘营养水平监测结果分析

Analysis of Monitoring Results of Iodine Nutrition Among Residents in Hongkou District of Shanghai

目的了解上海市虹口区居民的碘盐普及情况,为调整相应干预措施提供依据。方法按照《上海市碘营养状况调查方案》要求,对上海市虹口区进行片区划分,对5个街道的202名8~10岁学龄儿童以及101名孕妇进行盐样、尿样和甲状腺肿大率的检测。结果共检测8~10岁学龄儿童盐样202份,碘盐覆盖率为67.8%,合格碘盐食用率为55.9%,碘盐合格率为82.5%,非碘盐率为32.2%。检测孕妇家中食用盐101份,碘盐覆盖率为79.2%,合格碘盐食用率为67.3%,碘盐合格率为85.0%,非碘盐率为20.8%。检测8~10岁儿童尿样202份,尿碘中位数188.88μg/L,低于50μg/L的比例为5.94%。检测孕妇尿样共计101份,尿碘中位数129.19μg/L,尿碘低于50μg/L的比例为15.84%。8~10岁儿童甲状腺肿大率为0.50%。结论虹口区居民未达到碘盐覆盖率及合格碘盐食用率的目标,8~10岁学龄儿童及孕妇的平均尿碘水平达到国家消除碘缺乏病标准,有0.50%的8~10岁学龄儿童患有甲状腺肿大。应进一步加强健康教育科普工作,提高相应人群的碘盐食用率。

Objective To understand the iodized salt popularity and iodine nutrition status of residents in Hongkou District of Shanghai,and provide a basis for adjusting corresponding interventions.Methods According to the requirements of the Shanghai Iodine Nutrition Survey Plan,the Shanghai Hongkou District is divided into 5 regions.A total of 202 school-age children aged 8-10 years and 101 pregnant women were tested for salt,urine,and goiter rates.Results A total of 202 samples of school-age children aged 8-10 years were tested.The coverage rate of iodized salt was 67.8%.The qualified iodized salt consumption rate was 55.9%.The qualified rate of iodized salt was 82.5%.Detecting 101 edible salts in pregnant women's homes,the coverage rate of iodized salt was 79.2%,the qualified iodized salt consumption rate was 67.3%,the qualified rate of iodized salt was 85.0%,and the non-iodized salt rate was 20.8%.A total of 202 urine samples from children aged 8 to 10 were tested.The median urine iodine was 188.88μg/L,and the ratio was less than 50μg/L,which was 5.94%.A total of 101 urine samples were detected from pregnant women.The median urine iodine was 129.19μg/L.The proportion of urine iodine below 50μg/L was 15.84%.The goiter rate in children aged 8-10 was 0.50%.Conclusion The residents of Hongkou District did not reach the targets of iodized salt coverage and qualified iodized salt consumption rate.The average urine iodine level of school-age children aged 8-10 years and pregnant women rea-ched the national standard for eliminating iodine deficiency diseases;0.50%of school-age children aged 8-10 have goiter,so health education should be further strengthened to increase the iodized salt consumption rate of the corresponding population.
