| Abstract:: |
| Objective To study the effect of occupational X-ray exposure on non-cancer diseases of radiation workers.Methods The medical X-ray workers in Chongqing mumicipality were surved in 1980. In 2020, the previous 91 medical institutions distributed across 41 districts and counties of Chongqing continued to be selected as the survyed units, including 53 grade-A top-class hospitals. Using the method of prospective cohort study, the fifth follow-up survey was conducted for Chongqing's medical X-ray workers and the control groups in 1980 with respect to their personal information, occupational radiation exposure, disease history and others. The incidence rate, relative risk (RR) and 95% confidence interval of diseases in each system were analyzed.Results There were 937 individuals in this cohort. So far, 359 cases of non-cancer diseases had been counted. Compared with the control group, the relative risk RR of cardiovascular system, ophthalmology and other unclassified diseases in the exposure group were 1.50, 2.03 and 2.64(χ2=5.97,3.97,4.25, P <0.05), respectively. The adjusted confounding factors showed that the RR of the incidence rate of cardiovascular, ophthalmic and digestive diseases in the female exposure group was generally higher than that in the control group(RR=2.33,2.59, 7.55; χ2= 7.28, 4.17, 8.64, P < 0.05), respectively. The RR of the incidence rate of cardiovascular and ophthalmic diseases in exposure group was generally higher than that in the control group among 25-29 year-old workers(RR=2.26, 5.07; χ2 =8.22, 4.91, P < 0.05), respectively. For compasion between the the accumulated dose groups, the incidence rate of cardiovascular system, ophthalmology and digestive system diseases in the exposure group was generally higher than that in the control group(RR=1.86, 2.91, 3.59; χ2= 9.83, 8.21, 5.58, P < 0.05), respectively.Conclusions The non-cancer risk of X-ray workers exposed to long-term occupational exposure was increased, among which the risk of cardiovascular system, digestive system, ophthalmic diseases and others might be related to the occupational exposure. |
