【摘要】 对缺碘及对照区7～13岁儿童作了碘代谢和甲状腺机能、神经心理机能、听力、前庭功能、体格发育、骨发育和智商测定,结果表明:碘缺乏区智力低下儿童主要见于碘供不稳定时出生者;碘缺乏区碘供充足后出生的儿童智商与对照组无异;除智商外的其它指标,碘缺乏区与对照组无异。因此,作者认为,碘供充足时,不但可保持正常的神经心理和生长发育,而且还可提高碘缺乏区儿童智商。更多还原

【Abstract】 Measurements were made on iodine metabolism, thyroid function, neurop-sychic, somatic and bone growth, hearing ability, vestibule function and inel-ligence quot ient (IQ) of children aged 7-13 years in iodine deficient areas with those in normal areas as control. Results showed that in iodine deficient areas, most of the lower intelligent children were born when iodized salt was not well suplied, whereas, there exist no difference in IQ between children in normal areas and those who were born when iodine was well suplied in iodine deficient areas, And there was no significan difference in other indices of children in normal and iodine deficient areas. It was indicated, therefore, sufficent iodine supplement could not only keep children’s normal neuropsy-chic and somatic development, but also improve their intelligence.更多还原
