摘要
目的掌握2011年《食用盐碘含量》标准实施后,上海市闵行区学龄儿童与孕妇的碘营养状况。方法按照《上海市碘缺乏病监测方案》要求,2015-2019年在上海市闵行区按东、西、南、北、中划分5个抽样片区,每个抽样片区抽取1个街道(镇),每个街道(镇)各随机抽取1所小学,每所小学抽取40名8~10岁非寄宿学生;每个街道(镇)随机抽取20~30名孕妇。采集所有调查对象尿样及其家中食用盐样,测定尿碘和盐碘含量。结果 2015-2019年儿童尿碘中位数为186.3μg/L,除2017年尿碘水平为252.0μg/L,其余年份比较稳定,在176.5~179.2μg/L之间;孕妇尿碘中位数为148.0μg/L,除2017年尿碘水平为225μg/L,其余年份在128.0~147.5μg/L之间。儿童碘缺乏和碘过量比例分别占13.8%和15.2%,孕妇碘缺乏比例占50.7%。儿童和孕妇家中食用盐碘盐含碘量中位数分别为23.6 mg/kg和22.9 mg/kg。儿童和孕妇合格碘盐食用率和碘盐覆盖率分别为55.1%、54.4%和71.4%、78.4%,均有逐年下降趋势。结论上海市闵行区8~10岁学龄儿童碘营养水平适宜,但孕妇碘营养水平不足,存在碘缺乏的风险。需加强对孕妇碘营养健康教育和碘营养水平监测评估。
Objective To understand the iodine nutritional status of school-age children and pregnant women in Minhang District of Shanghai form 2015 to 2019.Method Between 2015 and 2019,according to the Monitoring plan for iodine deficiency disorders in Shanghai,Minhang District was divided into five sampling areas according to the east,west,south,north and middle of the district.One street( town) was selected from each sampling area,and one primary school was randomly selected from each street( town).40 non boarding students aged 8-10 were selected from each primary school;and 20-30 pregnant women were randomly selected from each street( town).Urine and salt samples of all the subjects were collected,and the contents of urine iodine and salt iodine were determined.Results From 2015 to 2019,the median of urinary iodine in children was 186.3 μg/L.Except for 252.0μg/L in 2017,it was stable in other years,ranging from 176.5 μg/L to 179.2 μg/L.The median of urinary iodine in pregnant women was 148.0 μg/L.Except for 225.0 μg/L in 2017,it was from 128.0 μg/L to 147.5 μg/L in other years.13.8% of children were iodine deficient and 15.2% were iodine excess,and 50.7% of pregnant women were iodine deficient.The median iodine content of iodized salt for children and pregnant women was 23.6 mg/kg and 22.9 mg/kg,respectively.The qualified iodized salt consumption rate of children and pregnant women were 55.1% and 54.4%,respectively.The iodized salt coverage rate of children and pregnant women were 71.4% and 78.4%,respectively.Both of these two rates are declining year by year.Conclusion The iodine nutrition level of school-age children aged 8-10 in Minhang District of Shanghai is suitable,but the iodine nutrition level of pregnant women is insufficient.It is necessary to strengthen the health education,monitoring and evaluation for iodine nutrition of pregnant women.
