ABSTRACT
Objective To explore the relationship of dynamic changes between the iodine nutritional condition and growth of children born before and after the implementation of universal iodine.Methods By means of sampling investigation,urinary iodine and goiter,height,weight,intelligence quotient(IQ)were comprehensively evahated in children aged 7～14 years old born before and after the implementation of iodine in 10 counties and 2 cities of Qiannan.Results The median of urinary iodine of children Was 91.88μg/L in 1984,133.33μg/L in 1994,316.00μg/L in 2006;goiter rate was 21.40%(122/570)in 1984,12.86%(107/832)in 1994,5.28%(45/851)in 2006;the average IQ was 89.18±4.10 in 1994,94.26±0.94 in 2006;children in each age group in 2006 has a higher height and a heavier weight compared with those in 1984.Conclusion The physical development and intelligence of children in the areas of iodine deficiency have improved along with the correction of iodine deficiency.
ABSTRACT
Objective To investingate the iodine-nutritional status of the rural children form 8 to 10 years old after salt iodzation had been implemented in Qiannan State.Methods The size of thyroid gland waft measured by palpation in 421 rural children aged 8～10 years old in Qiannan State.Calorimetric eerie-arsenic assay and vitriolic ammonium assimilmion were used for testing urinary iodine,while Rsvens test was used to test the intelligent quotient (IQ).Results The rate of goiter was 5.0%(21/421).The median of urinary iodine Was 331.2μg/L The average IQ was 93.32±18.68 of the children aged 8～10.The IQ of children with different iodine-nutritional level was significantly different(P＜0.05).Conclusions The children's iodine nutrition in Qiannan State has been improved after the salt adds the iodine.Their intelligence level is quite normally.Iodine dificiency disease has been eliminated according to the national standard in terms of 8～10 year old child ufinaty iodine level and goiter rate.
