Abstract:
Objective:To learn the levels of thyroid hormone indicators among interventional and diagnostic radiologists, so as to provide insights into occupational health monitoring of radiologists.
Methods:Demographic information, body mass index (BMI), thyroid hormone indicators and cumulative individual doses over 5 years among interventional and diagnostic radiologists were collected through the personal dosimetry monitoring database of Ningbo Center for Disease Control and Prevention and the Occupational Health Examination Center of a tertiary hospital in Ningbo City. The thyroid hormone indicators of different job types and cumulative individual doses over 5 years were analyzed, and factors affecting the thyroid hormone indicators were identified using a multivariable ordinal logistic regression model.
Results:There were 159 interventional and 159 diagnostic radiologists included, and the proportions of abnormal thyroid hormone indicators were 9.43% and 12.26%, respectively, with no statistically significant difference (P>0.05). The levels of triiodothyronine and free triiodothyronine in interventional radiologists were lower than those in diagnostic radiologists [(1.54±0.41) vs. (1.68±0.34) nmol/L, (5.13±1.07) vs. (5.55±0.87) pmol/L; both P<0.05]. The levels of triiodothyronine and free triiodothyronine were significantly different among radiologists with cumulative individual doses over 5 years of <1.5 mSv, 1.5-<3.0 mSv and ≥3.0 mSv [(1.69±0.31), (1.69±0.40) vs. (1.52±0.41) nmol/L, (5.60±0.83), (5.32±0.94) vs. (5.14±1.09) pmol/L; both P<0.05]. Multivariable ordinal logistic regression analysis identified BMI (<18.5 kg/m2, OR=0.111, 95%CI: 0.028-0.436) and cumulative individual doses over 5 years (<1.5 mSv, OR=6.259, 95%CI: 2.368-16.547) as the factors affecting triiodothyronine, and job types (diagnostic radiologists, OR=3.171, 95%CI: 1.529-6.574), BMI (18.5-<24.0 kg/m2, OR=0.393, 95%CI: 0.184-0.842), and gender (men, OR=3.449, 95%CI: 1.294-9.190) as the factors affecting free triiodothyronine.
Conclusion:Occupational exposure has a certain impact on the thyroid hormone indicators among interventional and diagnostic radiologists, and the main influencing factors include BMI, radiation dose, job type and gender.
