摘要
目的研究环境碘过量对甲状腺容积的影响。方法在推算碘摄入量为1961.0μg/d的碘过量和碘摄入量255.1μg/d的对照乡随机检测8～10岁学生甲状腺B超容积、测定身高体重、计算体表面积。结果碘过量8～10岁学生甲状腺容积中位数2.8mL(水平3.08±1.06),显著低于碘正常的中位数3.6mL(水平3.64±1.13)。结论此次发现的重度环境碘过量使甲状腺容积显著缩小,具有理论意义和实用价值。
Objective To evaluate the effect of iodine excess on thyroid volume of school children. Methods 218 and 127 school children aged 8 - 10 years old were randomly sampled from iodine excess and control village, with the estimated iodine intake of 1 961.0 μg/d and 255.1 μg/d, respectively. Thyroid volume was measured by ultrasonography. Body surfaced area was calculated by weight and height. Results Median and mean of thyroid volume of children in high iodine area was significantly higher than that in normal iodine area （ 2.8 mL vs 3.6 mL, P 〈 0.05 ; 3.08 ± 1.06 vs 3.64 ± 1.13, P 〈 0. 05, respectively ）. Conclusions It＇s important in theory and practice that thyroid volume significantly decrease among school children when they expose to severe iodine excess.
