Abstract:
Objective:To understand the lens condition of radiation workers in a city, explore the factors affecting lens opacity, and provide basis for strengthening the radiation protection management of radiation workers.Methods:In December 2020, according to the national radiation health monitoring project, the occupational health examination data of radiation workers in an occupational health examination institution in a city from December 2018 to November 2020 were collected, including the basic information of radiation workers and ophthalmic examination results. The lens conditions of radiation workers in different subgroups were analyzed, and the influencing factors of lens opacity were analyzed by multifactor logistic regression.Results:A total of 4452 radiation workers were included, of which 439 (9.9%) had lens opacity. The lens opacity rate of male radiation workers was higher than that of female radiation workers ( P<0.05) . With the increase of age and length of service, the lens abnormalities of radiation workers increased ( rs=0.269, 0.212, P<0.01) . The lens opacity rate of radiation workers engaged in nuclear medicine was high (12.7%, 9/71) . The rate of lens opacity in off-the-job medical examination radiation workers was high (18.3%, 26/142) . By multivariate logistic regression analysis, the risk of lens opacification in the age ≤30-year-old group and the >30-<50-year-old group were 0.087 times (95% CI: 0.058-0.132) and 0.076 times (95% CI: 0.054-0.107) that in the age ≥50-year-old group, respectively. The risk of lens opacification in the age ≤10-year-old group, >10-<20-year-old group and 20-30-year-old group were 0.293 (95% CI: 0.189-0.456) , 0.413 (95% CI: 0.256-0.666) and 0.318 (95% CI: 0.204-0.497) times, respectively. Conclusion:The lens opacity rate of radiation workers is related to age and working age.Attention should be paid to high-age and long-term radiation workers to ensure their health.
