Analysis on children's psychomotor state among different IQ levels in iodine deficiency disorders regions

  Objective   To evaluate the level of children's IQ and psychomotor in different iodine deficiency disorders regions.

  Methods   Intelligence quotient(IQ)was measured by Raven Progressive Matrix(CRT-C2)and psycho motor were detected by Jin Yi Psychomotor Test Battery(JPB).

  Results   The distribution of children's IQ levels was significantly different in the severe, moderate and mild regions(P < 0.01), and the intelligent retarded rates were 2.34%, 4.52%, and 0.99%, respectively.The intelligent retar ded rates of the severe or moderate region were significantly hig her than that of the mild region(P < 0.01).The results of T value showed that abnormal rates of psy chomotor had significant difference between the severe, or moderate, mild regions, and the abnormal rates were 12.89%, 13.57%, 4.93%, respectively.The abnormal rates had significant difference(P < 0.01)among different regions between different IQ levels.The abnormal rates increased with the IQ levels decreased.

  Conclusion   The levels of children's IQ and psycho motor in the severe and moderate iodine deficiency disorders regions were significantly lower than those in the mild region.The abnormal rates of psycho motor increased with the IQ levels decreasing.
