介入工作人员颈动脉内中膜增厚的危险因素

目的 研究介入放射工作者颈动脉内中膜厚度(IMT)的危险因素,探讨IMT与累积受照剂量之间的关系。方法 采用1:4配比对照研究,在山东省选取155名医院介入工作者和620名普通放射科工作者,超声测量他们的IMT,收集其累积受照剂量及其他危险因素信息,SPSS分析IMT与累积受照剂量等危险因素之间的关系。结果 IMT和累积剂量、年龄、放射工龄呈弱相关,和性别呈较弱负相关;累积剂量、年龄、性别保留在线性回归方程中。结论 累积剂量、年龄增长可促进IMT增厚,而性别则相反。

Risk factors of Carotid Arterial Intima-Media Thickness of Intervention Workers

Objective To investigate the risk factors of carotid arterial intima-media thickness (IMT) of intervention workers,especially for the relationship between IMT and accumulated dose of radiation. Methods 1:4 matched case-control study was carried out. The study subjects consisted of 155 intervention workers and 620 diagnostic X-ray workers coming from different hospitals in Shandong province. IMT was measured by ultrasound, meantime their accumulated dose of radiation and other risk factors were collectd. necessary analysis was applied with SPSS. Results There exists a weak positive correlation between IMT and accumulated radiation dose, age and radiation senioroty, contrarily gender shows weak negative correlation. Finally accumulated dose,age and gender remain in the linear regression equation. Conclusion Accumulated radiation dose, age may promote IMT thickening while gender the opposite.
