Study on Preventive Effection of Semi-clinical Impairment of Children Whose Mothers Taking Iodized Oil Capsule at Period of Pregnancy

Objective To observe and compare state of semiclinical impairment of children whose mothers have taken iodized oil capsules or iodized salt at serious iodine deficiency disorder regions and no supplied iodine at mild deficiency regions.Methods To test IQ psychomotor audition boneage weight and height of 3 groups children who are 7-13 years old with CRT-C2 JPB diagnostic audiometer X-ray weight and height instrument.Results Means of IQ at 3 group are 98.2±15.3(iodized oil caspule group)、93.5±15.7(iodized salt group)、94.2±16.2(no supplied group).The children whose IQ being 50-69 are 2.3%、7.1% and 7.5%.The JPB incidences rate of children are 1.0%、4.5%、 4.4%.The descend of audition are 1.9%、5.4%、5.6%.The delay of bone age are 4.4%、7.4%、7.8%.The delay of height are 4.2%、7.1%、7.3%.The delay of weight are 2.4%、4.3%、 414%.The means of IQ of Iodized oil caspule group is higher than iodized salt group and no supplied salt group(P<0.001).The incidences of delay of IQ.JPB audition bone age and height is lower than other groups(P>0.05)but there is not significant at IQ JPB audition bone age and height between iodized salt group and no supplied iodine group.Conclusion It is feasible and a good way to supplied iodized oil capsule for pregnancy women.
