南京市从事放射作业人员甲状腺超声检查结果分析

An analysis on the results of thyroid ultrasound examination in personnels engaged in radiation operations

目的分析放射作业人员甲状腺超声检查结果,为放射作业人员甲状腺病变的监测和管理提供依据。方法以南京市3565例从事放射作业人员为观察组(A组),以不接触射线的1697例其他人员为对照组(B组),进行甲状腺超声检查,比较两组检查结果,对A组的性别差异和射线暴露时间进行分层分析。结果 A组3565例射作业人员中,检出1195例患有不同类型的甲状腺病变,患病率33.5%,高于B组的27.1%(P<0.01);其中,A组甲状腺结节781例,患病率为21.9%,高于B组的18.4%(P<0.01)。A组中,女性甲状腺病变患病率40.5%,高于男性的30.2%(P<0.01)。随着接触射线工龄的增长,甲状腺病变的患病率也随之增高(P<0.01)。结论从事放射作业人员,尤其是女性的甲状腺病变患病率高于常人,需要重视对从事放射作业人员甲状腺病变的监测和管理。

Objective To analyze the results of thyroid ultrasound examination in the personnels engaged in radiation operations for providing the evidence of monitoring and managing the thyroid lesions of them.Methods Thyroid ultrasound examination was performed in 3565 personnels engaged in radiation operations（group A）and 1697 personnels without touching radiation（group B）.The results were compared between two groups.The stratification analysis in the differences of gender and exposure time in group A was carried out.Results Of 3565 personnels engaged in radiation operations,1195 cases were detected to have thyroid lesions in different kinds.The incidence of thyroid lesions was higher in group A than that in group B（33.5% vs.27.1%）（P〈0.01）.The incidence of thyroid nodule was higher in group A than that in group B（21.9% vs.18.4%）（P〈0.01）.The incidence of thyroid lesions in group A was higher in female than that in male（40.5% vs.30.2%）（P〈0.01）.The prevalence of thyroid lesions in group A was increased as the ray-contacted time was prolonged（P〈0.01）.Conclusion The incidence of thyroid lesions is higher in the personnels engaged in radiation operations,especially in the females,for whom attention should be paied to the monitoring and management of thyroid lesions.
