2728例体检人群甲状腺结节的流行病学调查

目的了解2728例体检人群甲状腺结节发病情况。方法选择2011年1月至2011年9月杭州市20岁以上,在我院作甲状腺物理和超声检查的健康体检人群2728人,分析其甲状腺检出率情况,并比较物理和超声检查甲状腺的检出率。结果受检人群物理检查出甲状腺结节82例,检出率3℅,其中男性检出17人(1℅),女性检出65人(6%);超声检查检出490例,检出率17.96%,其中男性检出237人(14.29%),女性检出253人(23.67%);女性显著高于男性(P<0.001),且检出率随年龄的增加而增高(P<0.001)。超声检查较物理检查可有效提高检出率(P<0.05)。结论体检人群中甲状腺结节检出率较高,且随年龄的增加而增高,女性高于男性;超声检查可有效提高检出率。

An epidemiological investigation of the thyroid nodules found in a group of 2728 undergoing health check

Objective The study attempted to understand the incidence of thyroid nodules.Method 2728 people aging over 20 who came to the hospital for health check during the period of time from January 2011 to September 2011 were chosen as the subjects for the study,which was intended to find out the incidence rate of thyroid nodules and to compare the physical technique and ultrasonographic technique in detecting the incidence.Result The physical technique detected nodules in 82 of subjects.The detection rate was 3 percent.Among them,17 were male and 65 were female persons.The ultrasonographyic technique found nodules in 490 subjects.The detection rate was 17.96%.Among them,237 were male and 253 female.The number of female persons who had nodules was considerably larger than that of male subjects(P<0.001).The detection rate increased as the age of subjects increased(P<0.001).Ultrasound examination worked more effectively than physical technique.Conclusion Incidence rate of thyroid nodules was high and increased as,the age increased.More cases were found in females than in males.The ultrasound examination can effectively improve the detection rate.
