1999年全国8～10岁儿童甲状腺容积调查

摘要

Objective　To discover and discuss the charac ter and statistics of frequency distribution of thyroid volume (TV) in Chinese c hildren aged 8,9,10 years for setting up an effective strategy to control the endemic goiter in China.Methods　The TV is measured by B-ultrasonography.The da ta of a great sample collected from all country are treated with computer centra lly in Chinese Research Center for Endemic Disease Control.Results　①In 1999,the statistics of TV(ml) of children aged 8,9,10 years in China are 3.6 of mean,3.4 of median,3.0 of mode,5.9 of 95% point and 7.9 of 99% point.②The values of 95% point in frequency distribution of TV in 8,9,10 years of boy in order are 4.8,5.6 and 6.3,and in girl they are 5. 2,5.8 and 6.5.③The disparity in medians of TV of children is very significant between the studied provinces;the lowest is Shanghai,the mediums are Anhui and Sh anxi,and the higher ones are Chongqing,Guizhou and Xinjiang,and the medians of the TV in these three categories are 1.2,3.7 and 4.0 in order.④Differential effe cts of palpation method in detection of TV are discussed carefully in this paper .Conclusions　The cause inducing to the significant diffe rences of children TV in several regions in China is not known yet,but it is not the nutritional problem of iodine certainly.%目的　分析1999年全国8 ～10岁儿童甲状腺容积的频数分布及其统计值，为建立有效的地方性甲状腺肿防治策略服务。方法　收集全国案例用B超法测定甲状腺容积，在中国地方病防治研究中心处理。结果　①全国8～10岁儿童甲状腺容积统计值（ml）为，均 数3.6、中位数3.4、众数3.0、95％分位数5.9、99％分位数7. 9。②全国8～10岁儿童甲状腺容积95％分位数，男性依次为4.8，5.6，6.3 ml ，女性依次为5.2，5.8，6.5 ml。③甲状腺容积地区差明显，按中位数计算最低 上海1.2 ml，居中安徽、山西3.7 ml，居高重庆、贵州、新疆4.0 ml。④对触诊 法的适用性问题做了详细讨论，认为可用。结论　全国8～10岁儿童甲状腺容积地区差非常明 显，原因未详。
