补碘对7～12岁轻度碘缺乏病儿童脑功能及生长、发育的影响

Effects of Iodine Supplement on the Function of Brain and Growth,Development of Body to Minor IDD School Children of 7～12 Years Old

通过半年对３５名７～１２岁轻度碘缺乏病儿童进行补碘，并与同龄、同地的正常儿童和缺碘未补碘儿童进行比较，以观察补碘对儿童脑功能及生长发育的影响。结果发现：①补碘可使儿童碘营养状况恢复正常，尿碘值由（８３．２±３．５）μｇ／Ｌ上升到（１６２．２±１．６）μｇ／Ｌ，血清Ｔ４、ＦＴ４Ｉ和ｒＴ３：也与正常儿童一致而与未补碘儿童有显著性差异（Ｐ＜０．０５）．②轻度碘缺乏病儿童智商低于正常儿童（Ｐ＜０．０１），补碘在一定程度上改善其智商水平。③轻度碘缺乏病及补碘未能明显影响儿童的生长发育，可能与儿童总营养水平较差有关。

Through a half year study of iodine supplement in 35 minor IDD school children of 7～12 years old compared with normal and control groups,the results showed:(1)Iodine supplement would make the body iodine level return to normal.The level of urine iodine rose from(83.2±3.5)μg/L to(162.2±1.6)μg/L.The serum T4,FT4I and rT3 showed no difference with normal children,but were significantly different from control children (P<0.05).(2)The IQ of minor IDD children was lower than that of normal children and oral iodized oil pellet could improve the IQ to a certain extent.(3)Minor IDD and supplement of iodine didn't have a remarkable influence on the growth and development of children,which was probably concerned with malnutrition.
