目的　研究我国医用诊断X射线工作者中高血压病发病的危险因素 ,探讨长期职业受照与高血压发病之间的关系。方法　采用整群随机抽样的方法 ,在全国范围内选取 2 88对 1∶2配比的医用诊断X射线工作者高血压患者及相应对照 ,问卷调查各种可能的危险因素 ,归一化工作量法估算累积受照剂量 ,SAS软件COX比例风险模型进行单因素及多因素条件Logistic回归分析。结果　超重 (OR =3 0 87,P =0 0 0 1)、高血压家族史 (OR =3 14 0 ,P =0 0 0 1)、担心从事放射工作有害健康 (OR =1 798,P =0 0 10 )是我国X射线工作者高血压 3个主要危险因素 ;将性别、参加工作年代分层后 ,男性、早期参加放射工作者中较大剂量受照同高血压呈正相关 (OR =5 6 72 ,P =0 0 2 2 )。结论家族史、超重是X射线工作者高血压主要危险因素 ,职业紧张在X射线工作者高血压中发挥一定的作用 ,较大剂量受照可能与高血压有关 Objective To study the risk factors of hypertension in medical diagnostic X-ray workers in China and to explore the relationship between long-term occupational exposure and the incidence of hypertension. Methods A cluster random sampling method was used to select 2 88 pairs of 1: 2 proportion of patients with hypertension in medical diagnostic X-ray workers and their corresponding controls in the whole country. Various possible risk factors in the questionnaire were surveyed, and the normalized workload Method to estimate cumulative exposure dose, SAS software COX proportional hazard model for single factor and multivariate conditional Logistic regression analysis. The results were overweight (OR = 3 0 87, P = 0 0 0 1), family history of hypertension (OR = 3 14 0, P = 0 0 0 1), concerns about the health of radiological work (OR = 0 0 10) is the three major risk factors of hypertension in X-ray workers in our country. After stratified by gender and working age, the higher doses of male and early radiographers were positively correlated with high blood pressure (OR = 5 6 72, P = 0 0 2 2). Conclusion Family history and overweight are the major risk factors for hypertension in X-ray workers. Occupational stress plays a role in the hypertension of X-ray workers. The higher doses may be related to hypertension
