Abstract

Objective Investigation and analysis of intelligence and psychomotor function in children born after implementingt universal salt iodization(USI). Methods Historical serious illness areas of water iodine below 10μg/L were selected as study sites, water iodine in 50 - 100 μg/L in the historical non-endemic areas were as control points in Henan, 2008. Cluster sampling was used to select children aged 6 - 15 years as observing subjects,IQ were measured with CRT- Man Test(CRT-C2). A "Tianjin Medical psychomotor test battery" (JPB) was carry out to test psychomotor function. Results In IDD regions 230 children were surveyed post-USI and 1284 children preUSI. The IQs post and pre USI were 99.3 and 99.9, respectively, and the proportion of IQ ≤69 were 2.17%(6/230) and 2.80%(36/1284), respectively. In non-IDD regions 650 children were surveyed post-USI and 2079children pre-USI. The IQs post and pre USI were 95.3 and 93.8, respectively, and the proportion of IQ ≤ 69 were 2.31%(15/650) and 3.37%(70/2079), respectively. In IDD regions, the abnormal rate of T scores and damage index post USI were 3.6%(2/56), 5.3%(3/56), respectively, significantly lower than pre USI [18.1%(29/160),18.1%(29/160), x2 = 7.54, 6.86, all P ＜ 0.01]. Conclusions USI could increase the IQs of children and decrease the positive rate of JPB, and significantly improve the quality of whole nation and persistently eliminating IDD.

2009年河南省普遍加盐前后6 ~ 15岁出生儿童智力和精神运动功能的研究

目的调查分析普及食盐碘化(USI)后新生儿智力和精神运动功能的变化。方法2008年选取河南省历史水碘浓度低于10μg/L的大病区作为研究点，以历史非流行区50 ~ 100 μg/L的水碘浓度为控制点。采用整群抽样的方法选取6 ~ 15岁儿童作为观察对象，采用CRT- Man测验(CRT- c2)测定智商。采用“天津医学精神运动测试组”(JPB)对精神运动功能进行测试。结果在IDD地区调查usi后患儿230例，usi前患儿1284例。USI后和USI前的智商分别为99.3和99.9，智商≤69的比例分别为2.17%(6/230)和2.80%(36/1284)。在非缺碘症地区，650名儿童接受了usi后的调查，2079名儿童接受了usi前的调查。USI后和USI前的智商分别为95.3和93.8，智商≤69的比例分别为2.31%(15/650)和3.37%(70/2079)。IDD地区USI后T评分和损伤指数异常率分别为3.6%(2/56)、5.3%(3/56)，显著低于USI前[18.1%(29/160)、18.1%(29/160)，x2 = 7.54、6.86，均P < 0.01]。结论USI可提高儿童智商，降低JPB阳性率，显著提高国民素质，持续消除IDD。关键词:碘化物;盐;情报;精神运动功能
