Objective@# To investigate the
thyroid functions and influencing factors among
radiation workers in Wuhan City, so as to provide insights into
occupational health monitoring among
radiation workers.@*
Methods @#
Radiation workers receiving
physical examinations in Wuhan Prevention and
Treatment Center for
Occupational Diseases from January to October 2022 were enrolled, and participants'
gender, age,
smoking,
alcohol consumption, medical
history, medication use, types of occupational
radiation and
work duration were collected.
Triiodothyronine (TT3),
thyroxine (TT4), free
thyroxine (FT4), free
triiodothyronine (FT3) and
thyroid stimulating hormone (TSH) were measured using a
magnetic microparticle-based
chemiluminescence immunoassay.
Personnel dose equivalent was monitored using
thermoluminescent dosimetry, and annual cumulative
radiation dose was estimated. Factors affecting
thyroid function were identified using a multivariable
linear regression model.@*Results@#Totally 978
radiation workers were recruited, with a median age of 32.00 (interquartile range, 10.00) years, and including 782
men (79.96%) and 196
women (20.04%). There were 246
smokers (25.15%), 257
workers with
alcohol consumption (26.28%) and 489 with a
history of
radiation work (50.00%). The median annual cumulative
radiation dose was 0.20 (interquartile range, 0.24) mSv. The percentage of abnormal
thyroid function was 14.72%. Multivariable
logistic regression analysis showed that
women (OR=1.925, 95%CI 1.061-3.490),
history of
radiation work (OR=2.810, 95%CI 1.119-7.057) and involving in medical application (OR=1.915, 95%CI 1.101-3.332) were associated with abnormal
thyroid function.@*Conclusions@#The percentage of abnormal
thyroid function was 14.72% among
radiation workers in Wuhan City.
History of exposure to
ionizing radiation, types of occupational
radiation and
gender were main factors affecting
thyroid function.
