Analysis of detection and factors affecting the thyroid nodule among well logging radiation workers in Puyang,Henan
Objective To understand the prevalence of thyroid nodules and its influencing factors among well logging radiation workers in Puyang city,Henan province.Method Face-to-face written surveys were used;the occupational health examination data of well logging radiation workers in Puyang city,Henan province were collected from 2021 to 2022;the survey items included general demographic information,individual dose monitoring data,type of radioactive source,history of previous thyroid disease,and thyroid ultrasound results.Multi-variate logistic regression was used to analyze the influencing factors of thyroid nodules.Results A total of 553 participants,478 males and 75 females,were included.A total of 219 participants were found to have thyroid nodules,and the detection rate of thyroid nodules was 39.60％.The risk of detecting thyroid nodules was higher in women than that in to men(OR=3.054,95％CI:1.820-5.126);compared with the workers with less than 11 years of service,the workers with 31-40 years of service had an incresing risk of thyroid nodule detection(OR=2.342,95％CI:1.268-4.335);compared with the source repository custodians,those in the radiation well logging position(OR=8.404,95％CI:1.095-65.514)and radioactive operator position(OR=15.674,95％CI:1.850-132.800)had an increasing risk of detecting thyroid nodules.Conclusions It is advised to carry out proper radiation protection among the well logging radiation workers,strengthen occupational health examinations,and implement occupational health management.
