摘要
目的分析掌握江苏省苏州市重点人群碘营养水平,为科学调控碘缺乏病防治策略提供依据。方法 2017年按照《江苏省碘缺乏病监测方案(2017版)》要求,苏州市10个区(市),每个区(市)按东、西、南、北、中各随机抽取1个街道,每个街道各随机抽取1所小学,每所小学抽取8~10岁非寄宿学生40名,采集尿样和学生家中食用盐样;每个街道各抽取孕妇20名孕妇采集尿样和家中食用盐样。孕妇家庭户和学龄儿童户不重叠。盐碘和尿碘含量测定方法分别为直接滴定法和砷铈催化分光光度法。结果 2017年全市共监测居民食用盐3 000份,盐碘中位数为23.34mg/kg。碘盐覆盖率、碘盐合格率、合格碘盐食用率分别为98.33%(2 950/3 000)、98.31%(2 900/2 950)、96.67%(2 900/3 000),均达到碘缺乏病消除标准。共检测8~10岁儿童尿样2 000份,尿碘含量中位数为198.80μg/L。各区(市)儿童尿碘含量比较差异有统计学意义(χ~2=152.99,P<0.05),其中高新区最高,吴江区最低。600名儿童甲状腺B超肿大率为1.33%(8/600)。共检测孕妇尿样1 000份,尿碘含量中位数为176.49μg/L,各区(市)孕妇尿碘含量比较差异有统计学意义(χ~2=114.68,P<0.05),其中高新区最高,张家港最低。结论苏州市重点人群碘营养水平总体处于适宜水平,但仍需持续巩固碘缺乏病防治监测、深入开展碘营养科学研究。
Objective To realize the iodine nutritional status among the key population in Suzhou of Jiangsu Province, and to provide scientific basis for reasonable prevention and control of iodine deficiency disorders ( IDD ). Methods According to the " Jiangsu Iodized Salt Monitoring Plot Scheme" , total of 10 districts were selected in Suzhou in 2017. One street was selected by east, west, south, north and center in each district. Primary schools were chosen from each street. There were 50 streets and 50 primary schools in the whole city, and then 40 children aged 8 - 10 years ( half male and half female) were chosen from every primary school. Urine and salt samples from children's home were collected for examination. Moreover, twenty pregnant women were selected from each street and the examination of theses samples was the same as children' s. There is no overlap between the families of pregnant women and the families of children. Results Total 3 000 edible salt samples were tested and the median of salt iodine content was 23.34 mg/kg. The coverage rate of iodized salt and qualified iodized salt eonsumption rate were 98.33% (2 950/3 000) and 98.31% (2 900/2 950) respectively, which were up to the criteria for elimination of IDD. There were 2000 urine samples of children and 1 000 of pregnant women were tested. The median of urinary iodine were 198.8 μg/L and 176.49 μg/L respectively. There were significant differences between children urinary iodine status from different districts. It' s the same with pregnant women. The thyroid palpate swelling rate was 1.33% (8/600). Conclusions The iodine nutritional level of the key population was appropriate in general. However, surveillance and study on iodine nutrition should be continuously consolidated in the future.
