对贵阳市３００例新生儿进行了ＴＳＨ筛查，同时对９６４名８～１０岁儿童进行甲状腺肿大率检查，２１６名８～１０岁儿童作了尿碘测定，２４０户居民家的碘盐进行了监测。结果表明：１．ＴＳＨ值＞５ｍＩＵ／Ｌ者占３３．３％，其中＞１０ｍＩＵ／Ｌ者占１６．７％，＞２０ｍＩＵ／Ｌ者占４．３％，＞３０ｍＩＵ／Ｌ者占１．７％，表现向高值方向偏移。２．甲状腺肿大率平均为１１．４％。３．尿碘中位数值虽均大于１００μｇ／Ｌ，但仍有１．７％～２５．８％儿童尿碘达不到１００μｇ／Ｌ。４．碘盐浓度＞２０ｍＩＵ／Ｌ只占７０．４％。该结果提示贵阳市居民仍有碘摄入不足。以新生儿ＴＳＨ水平为判定人群碘营养状态指标最为敏感、可靠
TSH screening was performed on 300 newborns in Guiyang City. A total of 964 children aged 8-10 years were examined for goiter rate. Urinary iodine was measured in 216 children aged 8 to 10 and iodized salt in 240 households Monitoring. The result shows: 1. TSH> 5mIU / L accounted for 33.3%, of which> 10mIU / L accounted for 16.7%,> 20mIU / L accounted for 4.3%,> 30mIU / L accounted for 1.7%, the performance of high Value direction offset. 2. Goiter rate was 11.4% on average. 3. Although urinary iodine median values were greater than 100μg / L, but still 1.7% to 25.8% of children urinary iodine less than 100μg / L. 4. Iodized salt concentration> 20mIU / L only accounted for 70.4%. The results suggest that residents of Guiyang City, iodine intake is still inadequate. TSH levels of newborns to determine the status of iodine nutrition indicators of the population most sensitive and reliable
