【Abstract】 The investigation of body development and intelligence of the pupils in 4 primary schools （Two are in iodine-deficiency area and the other two are in lodine-sufficiency area） was conducted in order to approach the effect of iodine on growth and development of body and mind of teenagers and offer the basis of promoting their healthy development. The results are as followst There are no differences in height, weight, sitting-height and pulse between the pupils of 7-10 years old in the iodine-deficiency area and in the control area. The difference between the two groups of 11-14 years old is significant: There is no difference in blood pressure, but indeed, there are changes on electrocardiogram in the sick group. The attack rate of incomplete right branch block is higher than that in control area, P<0.01. Intelligenee of the pupils in the iodine-deficiency area trails by half an year or even over one year than that in control area. 50 x-ray films on hand in positive position were taken in the iodine-deficiency area, among which, bone-age of 21 cases was backward, accounting for 42%. In the iodine deficiency area, iodine absorptivity of schoolboys is 15. 56, while that of schoolgirls is 15.93. In control area, iodine absorptivity of schoolboys is 20.10, while that of schoolgirls is 22.74. There exist significant differences between the two groups, p<0.01. The serum T₃ and T₄ is also determined.更多还原
