7～14岁儿童IDD防治控制标准的研究

A STUDY OF CONTROL AND PREVENTION-TREATMENT STANDARD FOR CHILDREN AGED 7-14 IN IDD AREA

本文以未经补碘防治的IDD病区7～14岁儿童的尿碘、FT_4、TSH、智商、肿大率资料,作了相关回归分析和多元相关回归分析,证明各指标之间有显著相关意义(Pr<0.001),其回归方程线性作用均非常显著(Pb<0.001.P<0.01),其回归方程求证当尿碘为81μg/L时,肿大率≤20%、FT_4≥11.0ng/L、TSH≤7.0mU/L、IQ≥70。讨论认为只有达到上述指标水平病区7～14岁儿童方能保证智力等发育正常进行。故建议7～14岁儿童的上述数据应作防治控制标准。

This thesis has made a study of control and prevention-treatment standard for children aged 7-14in IDD area where no measure of iodized salt was taken. By means of correlative regression analysis and multiple correlative regression analysis, we discovered the close correlation between the UI and goiter rate FT4;TSH and IQ and notable linear action of regression equation as well.The regression equation demonstrated that when UI was up to 81ug/L, goiter rate was≤20%, FT_4≥11.Cng/L, TSH≤7.0mu/L and IQ≥70. Discussion held that only by keeping the children of IDD area up to the above-mentioned standard indexes,could they enjoy a normal intelligence developnm(?) ent. We, therefore, suggest that the above-mentioned indexes be taken as the control and prevention-treatment standard.
