目的了解厦门市海沧区实行全民食盐加碘防治碘缺乏病后碘盐质量以及8~10岁儿童、孕妇尿碘状况。方法在海沧区4个街镇随机抽取15个行政村(居委会),每个行政村(居委会)再抽取20户居民户,采集家中盐样;抽取5名孕妇,采集尿样。抽取7所小学,每所小学抽取8~10岁学生30名,采集尿样。盐碘测定采用直接滴定法,尿碘测定采用过硫酸铵消化一砷铈催化分光光度法。结果海沧区居民碘盐覆盖率均>95%;碘盐合格率除东孚为86.67%外,其余街镇均>90%。8~10岁儿童和孕妇尿碘中位数均>100μg/L,且<50μg/L的比例<10%。结论海沧区碘盐质量和儿童、孕妇碘营养都已经达到国家消除碘缺乏病阶段目标要求。
Objective To understand the quality of iodized salt and the status of urinary iodine in children and pregnant women aged 8-10 years after the implementation of universal salt iodization in Xiamen Haicang District. Methods A total of 15 administrative villages (neighborhood committees) were randomly selected from 4 towns in Haicang District. 20 villages were sampled from each administrative village (neighborhood committee) to collect salt samples from their families. Five pregnant women were collected to collect urine samples. Seven primary schools were drawn and 30 pupils aged 8 to 10 were taken from each primary school to collect urine samples. Salt iodine determination by direct titration, urinary iodine determination by ammonium persulfate digestion arsenic cerium catalytic spectrophotometry. Results The coverage of iodized salt in Haicang residents was> 95%. The pass rate of iodized salt was> 90% in the remaining towns except for 86.67% of Dongfu. The median urinary iodine of children aged 8-10 years and pregnant women were both> 100μg / L, and the proportion of <50μg / L was less than 10%. Conclusion The quality of iodized salt and the iodine nutrition of children and pregnant women in Haicang have all met the national target of eliminating iodine deficiency deficiency stage.
