Results and analyses of Doppler ultrasonic examination of thyroid nodules in male youngsters of the 4 regions

目的了解甲状腺结节在青少年男性中的发病率和地区性差异。方法对4个省4个地区共567名17～19岁男性青少年进行体检，采用彩色多普勒超声常规检查甲状腺，记录和分析甲状腺是否存在结节及结节的超声表现。结果4地青少年男性甲状腺结节平均发病率25．7％。沿海城市（山东烟台、辽宁大连）和内陆城市（安徽蚌埠、河南郑州）发病率分别为、25．0％、29．1％，两者差异无统计学意义（P〉0．05）。结论我国沿海与内陆城市的青少年男性甲状腺结节发病率均比较高，且发病率无明显差异。

Objective To know the prevalence of thyroid nodules in male youngsters and regional differences. Methods Physical examinations were made in the youngsters from the 4 regions of 4 provinces, with an age range of 17-19. Doppler uhrasonogra- phy was performed to record and analyze if there were thyroid nodules and their morphology. Results Average incidence of thyroid nod- ules for the male youngsters of the 4 regions was 25.7%. The incidences of thyroid nodule for the youngsters of the coastal cities （ Yan- tai and Dalian） and inland cities were 25.0% and 29.1% respectively. No statistical significance could be seen between them （P 〉 0.05 ）. Conclusion The incidence of thyroid nodules among the youngsters of both coastal and inland cities was relatively high, which might be correlated with the recommended intake of iodine-rich salt in recent years.
