Abstract:

Objective To analyze the influencing factors of thyroid abnormalities among non-medical radiation workers in Nantong City and provide a scientific basis for developing targeted occupational health protection strategies. Methods By convenient sampling,916 non-medical radiation workers were selected as the observation group from the physical examination data of radiation workers in Nantong City from May 1,2023 to April 30,2024,and 369 workers who had never been exposed to ionizing radiation were selected as the control group. The differences in thyroid structure,thyroid function,and thyroid abnormalities between the observation group and the control group were compared. Collect the occupational health examination data such as gender,age,body mass index(BMI),length of exposure to radiation,smoking,drinking,blood pressure,blood sugar,and occupational category of the staff in the observation group,and analyze the influence of each variable on thyroid abnormalities. Results Among the 916 radiation workers,128(13.97%) had abnormal thyroid structure,83(9.06%) had abnormal thyroid function,and 196(21.40%) had abnormal thyroid. The thyroid structure,thyroid function and thyroid abnormality rate in the observation group were all higher than those in the control group,and the differences were all statistically significant(χ2=31.148,7.272,34.850,all P<0.01). Age was positively correlated with thyroid structure and thyroid abnormalities(r=0.109,0.107,both P<0.01). The length of service exposed to radiation was positively correlated with thyroid structure,thyroid function and thyroid abnormalities(r=0.186,0.066, 0.185,all P<0.05). Multivariate Logistic regression analysis showed that women,those with longer exposure to radiation,and the industrial flaw detection group had a higher risk of thyroid structure,thyroid function,and thyroid abnormalities(all P<0.05). Conclusion Long-term exposure to low-dose ionizing radiation has a certain impact on thyroid abnormalities in non-medical radiation workers. Radiation protection for women,those with long exposure to radiation,and industrial radiographic workers should be strengthened.
