| Abstract:: |
| Objective To investigate risk factors of coronary heart disease (CHD) in medical diagnostic X-ray workers in China, especially the relationship of CHD with occupational irradiation. Methods A 1∶2 matched case-control study was carried out. The study subjects consisted of 112 pair-matched cases and controls coming from different hospitals in China. Information about occupational and non-occupational risk factors obtained by interviewing every subjects personally. Individual doses were estimated by normalized work load method. SAS 6.12 software conditional Logistic regression method was applied to data analysis. Results Variables such as family history of CHD (OR= 17.298, P=0.0001), history of hypertension (OR=6.172, P=0.0003), overweight (OR=2.679, P=0.0150), physical exercises (OR=0.421, P=0.0333), diabetes (OR= 7.823, P=0.0200), radiation protection condition(OR=3.992, P=0.0027), and accumulated radiation dose(OR=1.612, P=0.0454) were included in the last model. Conclusions For the medical diagnostic X-ray workers, family history of coronary heart disease , history of hypertension, diabetes, etc. are the main risk factors of CHD, and occupational exposure may be a potential risk factor. As for the mechanism, further studies are needed. ; |
