按照国标（ＧＢ１６３８）Ｂ超标准对２０１６例８～１０岁儿童的甲状腺体积进行了Ｂ超和触诊二种方法的调查比较分析，结果儿童甲状腺触诊肿大率明显高于Ｂ超测量的肿大率（Ｐ＜０．０１）。两种诊断方法的吻合率为７７．６％，若以Ｂ超作为标准，触诊的漏诊率和误诊率分别为６．９％和１５．５％；假阳性（误诊率）明显高于假阴性（漏诊率）。各年龄组的第９７％位数上限值均高于国外的资料。不同程度的甲肿经Ｂ超测量确诊率为４７．５％；其中可见性甲肿确诊率高达８２．４％，不可见性确诊率仅为４１．９％，有显著的统计学差异（Ｐ＜０．０１）。新疆碘缺乏病的流行程度仍十分严重，距儿童甲状腺肿大率＜５％的国家消除标准还相差甚远，其防治力度仍需加强
In accordance with the national standard (GB1638) B ultra-standard 2016 2016 cases of children aged 8 to 10 thyroid volume B-and palpation of the two methods of comparative analysis of the results of palpation in children with thyroid gland palpation was significantly higher than the B-measurement of swollen Greater rate (P <0.01). The coincidence rate of the two diagnostic methods was 77.6%. If B ultrasound was used as the standard, the misdiagnosis rate and misdiagnosis rate of palpation were 6.9% and 15.5% respectively; the false positive rate (misdiagnosis rate) was significantly higher than false Negative (missed diagnosis rate). The upper limit of the 97th percentile of each age group is higher than that of foreign countries. The degree of diagnosis of different degrees of thyroid by B-ultrasound was 47.5%, of which, the diagnosis rate of visible swollenness was 82.4% and the invisible diagnosis rate was only 41.9%, with significant statistical difference (P <0.01). The prevalence of iodine deficiency disorders in Xinjiang is still very serious, and there is still a long way to go before the national elimination criteria for goiter prevalence in children still need to be strengthened
