福建省从1993年以来曾对食盐加碘浓度采取多次调整,沙县从1995—1998年也曾在全县范围内中、小学中开展口服补碘工作,2002年正式执行的国家食盐碘含量标准35±15mg/kg开始对加碘上限作了规定,目的在于有效持续消除碘缺乏病。我们将调整补碘适宜量后,对1995年以来的4次儿童碘营养状况监测结果进行分析。1 材料和方法1.1 病情监测 全县分别于1995、1997、1999年和2001年每年于5月中旬统一采用人口比例概率抽样(PPS)方法抽查30所小学校,每所小学随机抽查40名8～10岁儿童,用触诊法检查甲状腺肿。判断标准按《碘缺乏病消除标准》GB16006——
Since 1993, Fujian Province has taken multiple adjustments to salt iodization concentration. From 1995 to 1998, Shaxian county also conducted oral iodization in primary and secondary schools in the county. In 2002, the national salt iodine content standard 35 ± 15mg / kg began to limit the upper limit of iodine, with the purpose of effectively and continuously eliminating iodine deficiency disorders. We will adjust the appropriate amount of iodine, since 1995, four children iodine nutrition monitoring results were analyzed. 1 Materials and Methods 1.1 Disease Surveillance The county in 1995, 1997, 1999 and 2001 each year in mid-May unified population probabilistic sampling (PPS) method checks 30 primary schools, each primary school randomly selected 40 8 to 10 Aged children, check the goiter by palpation. Judging criteria according to “iodine deficiency disorders eliminate standard” GB16006--
