Abstract:
Objective To find out prevelence of thyroid goiter on school-aged children in excessive iodine region of Shandong Province.Methods By employing B-ultrasonography and palpation method,the thyroid volume were investigated and the thyroid goiter rate were calculated among 6415 children aged 8～10 years old in execssire iodine region.Results By employing B-ultrasonography method.The volumes of thyroid in goiter children aged 8,9,10 years were(5.67±1.49),(6.07±1.24),(7.30±2.01)ml,respectively.The goiter rates were 28.84%(683/2368),20.89%(448/2144),11.82%(225/1903).The volumes of thyroid in non-goiter children aged 8,9,10 years were(3.36±0.67),(3.64±0.77),(4.02±0.94)ml.When the normal value of thyroid volume in 8 and 9 year-groups lowered 0.5 ml,the goiter rate would be changed to 18.20%(430/2368)and 12.92%(277/2144) respectively.The thyroid volumes of boys and girls were(4.20±1.38),(4.18±1.73)ml,respectively.The goiter rates of boys and girls were 21.92%(732/3340)and 20.29%(624/3075)respectively.The rates of goiter detected by palpation in 8,9 and 10 year-groups were 10.05%(238/2368),10.31%(221/2144)and 14.45%(275/1903) respectively.Conclusions Along with the increasing age,the volume of thyroid in children aged 8～10 is increasing in excessive iodine region of Shandong Province.But the goiter rate is decreasing ahmg the increasing age.This phenomena may be caused by improper normal value of thyroid volume.Therefore,the normal value of thyroid volume should be revised urgently.
