摘要
目的了解西藏自治区实行碘干预后儿童智力水平。方法采用人口比例概率抽样方法(PPS),在西藏自治区抽样调查30个县的30所小学,8～10岁学生尿碘、家中食用盐含碘量和智商,智商测验应用中国联合型瑞文测验(CRT-C_2)。结果西藏自治区碘盐覆盖率33．2%,合格碘盐食用率21．7%；儿童平均尿碘＜50μg/L占30．4%；智商为77．3(处于边缘水平),智力落后的比例高达32%。结论普及碘盐,加强宣传,对孕妇及育龄妇女应额外补碘。
Objective To investigate the level of child brain development after iodine supplementation in Tibet Autonomous Region. Methods Proportional probability sampling method was used to carried out the research in 30 elementary schools of 30 counties in Tibet, which included intelligence quotient of children aged 8～10 years,urinary iodine level and salt iodine. Results In Tibet, iodinated salt covered 33.2% of all, 21.7% of which was qualified. 30.4% of the children had a urinary iodine level less than 50 μg/L. Their intelligence quotient was averagely 77.3, children with retarded intelligence quotient reached 32%. Conclusions Supplementation of iodinated salt, health education, additional complementary iodization to pregnant woman and women at child bearing-age are very important.
