目的　了解新疆南部碘缺乏病区学生智商状况。方法　2003年 3~4月,在新疆南部碘缺乏病流行区喀什、和田对16个乡的中心小学的 5年级学生进行了智商测定,同时调查了各校学生甲状腺肿大情况并测定了部分学生尿碘。结果16所学校的 5年级学生平均智商为 71. 00~90. 80, 6所学校位于边缘状态, 8所处于中下水平,仅 2所学校学生达到中等水平,原重病区儿童智商仍明显低于原中等病区儿童智商,但智商与甲肿率及尿碘水平之间无相关性。结论　和田、喀什地区小学生智商仍处于较低水平。 Objective To understand the IQ of students in Iodine Deficiency Disorders in southern Xinjiang. Methods From March to April 2003, in Kashgar and Wada, a fifth-grade primary school pupil in 16 townships in southern Xinjiang, the prevalence of thyroid gland was measured and some of the students Urinary iodine.

Six schools were located at the edge of the border and eight were at the middle and lower levels with only two schools reaching medium level. There was no correlation between IQ and the rate of goiter and the level of urinary iodine in the original medium ward children. Conclusions Wada and Kashgar pupils’ IQs are still at a low level.
