摘要
目的了解《食用盐碘含量》新标准实施后云南省碘缺乏病病情及儿童碘营养情况，为制订和调整全省碘缺乏病防治策略和措施提供科学依据。方法采用多阶段抽样方法开展云南省碘缺乏病消除评价省级抽查，比较分析2010（调整前）和2015年（调整后）抽查结果，评价居民户盐碘含量、碘盐覆盖率、碘盐合格率、合格碘盐食用率，8～10岁儿童甲状腺肿大率和尿碘中位数变化情况。盐碘检测采用《制盐工业通用试验方法碘的测定））（GB／T13025-7-1999）；儿童甲状腺容积检查采用B超法，甲状腺容积计算及肿大判定采用《地方性甲状腺肿诊断标准》（WS276-2007）；尿碘检测采用《尿中碘的砷铈催化分光光度测定方法》（WS／T107-2006）。结果2010、2015年居民户盐碘含量中位数分别为30．6、22．4mg／kg，二者比较差异有统计学意义（U=317503．50，P〈0．01）。2010、2015年碘盐覆盖率分别为99．6％（1681／1688）、98．9％（2592／2622），碘盐合格率分别为98．6％（1657／1681）、89．7％（2325／2592），合格碘盐食用率分别为98．2％（1657／1688）、88．7％（2325／2622），二者比较差异均有统计学意义（x2=6．42、125．11、130．18，P均〈0．01）；儿童甲状腺肿大率分别为0．8％（25／3272）、1．4％（44／3245）；儿童尿碘中位数分别为289．0、157．3μg／L，二者比较差异有统计学意义（U=1121669．50，P〈0．01）。结论云南省食用盐碘含量下调后，儿童碘营养处于更加适宜水平。
Objective To understand the situation of iodine deficiency disorders and iodine nutrition of children in Yunnan Province after the implementation of new standard of salt iodine, and provide the basic data for prevention and control of iodine deficiency disorders. Methods Using multistage sampling method, Yunnan provincial evaluations for iodine deficiency disorders elimination were carried out. According to the comparative analysis of 2010 （pre-adjustment） and 2015 （post-adjustment） evaluation results, the changes of the median of salt iodine, the coverage rate of iodized salt, the qualified rate of iodized salt, the rate of qualified iodized salt consumption, goiter rate of school children aged 8 - 10 and the median of urinary iodine were evaluated. Salt iodine was tested using the ＂Salt Industry General Test Method for Determination of Iodine＂ （GB/T 13025.7-1999）; thyroid volume examination of children using B-scan uhrasonography, thyroid volume calculation and enlargement judgment using ＂Diagnostic Criteria for Endemic Goiter＂ （WS 276-2007）; and urinary iodine detection using ＂Urinary Iodine Arsenic Cerium Catalytic Spectrophotometry＂ （WS/T 107-2006）. Results The medians of salt iodine in 2010 and 2015 were 30.6 and 22.4 mg/kg, respectively, the difference was statistically significant （U = 317 503.50, P 〈 0.01）. The coverage rates of iodized salt in 2010 and 2015 were 99.6% （1 681/1 688） and 98.9% （2 592/2 622）, the qualified rates of iodized salt were 98.6% （1 657/1 681） and 89.7% （2 325/2 592）, and the rates of qualified iodized salt consumption were 98.2% （1 657/1 688） and 88.7% （2 325/2 622）, and the differences were statistically significant （x2 = 6.42, 125.11, 130.18, P 〈 0.01）; the rates of children goiter in 2010 and 2015 were 0.8% （25/3 272） and 1.4% （44/3 245）, respectively; the medians of urinary iodine of children were 289.0 and 157.3 μg/L, respectively, the difference was statistically significant （U = 1 121 669.50, P 〈 0.01）. Conclusion After decreasing of salt iodine level starting from 2012 in Yunnan Province, the children iodine nutrition condition is in a more proper level.
