缺碘地区影响学生智力因素分析

FACTORS INFLUENCING INTELLECTUAL DEVELOPMENT OF CHILDREN IN IODINE DEFICIENCY AREA

本文通过对承德缺碘地区7～14岁儿童智力调查,结果发现缺碘地区儿童智力明显低于非缺碘地区(晋县)同龄儿童(P<0.01),而且年龄与智商呈显著的负相关,说明缺碘是低碘地区儿童智力落后的主要原因之一。除缺碘因素外,学生受教育时间、学习环境、父母的职业、受教育程度以及师资水平对学生智力发育的影响也是不可忽视的因素。

This article reports an intelligence investigation of children aged 7 to 14 years in the iodine dificiancy area (Chengde). The average intelligence quotient (IQ) of children in the iodine deficiency area was significantly lower than that of cohorts in the iodine adequacy area (Jiengxian, P<0.01 ). There was a negative correlation between the IQ and the age of children in the iodine deficiency area.The results prove that iodine deficiency is the main cause of influencing intellectual development of children in the iodine deficiency area.
