浙江省部分地区放射工作人员职业健康的现状分析

Analysis of the current situation of occupational health among radiation workers in some areas of Zhejiang Province,China

目的了解浙江省放射工作人员职业健康的现状,为放射工作人员职业健康检查相关标准和管理制度的改进提供理论依据。方法收集职业健康体检机构的职业健康检查个案数据,包括基本信息、体检类型(岗前、岗中、离岗)、健康检查结果;分析职业健康检查结果在不同组别间的差异,并运用Logistic回归模型分析影响放射工作人员职业健康的影响因素。结果共收集个案资料5668份,男性占比86%,女性14%;与岗前组相比,岗中组三碘甲状腺原氨酸(T_(3))异常率,离岗组白细胞计数异常率均升高(P<0.05);与工业组相比,核燃料组甲状腺结构、甲状腺素(T_(4))异常率降低,T_(3)异常率增高,医学组甲状腺结构异常率增高(P<0.05);放射工作人员的甲状腺结构、白细胞计数异常率随工龄的增加而升高(P<0.05);女性放射工作人员的白细胞计数、甲状腺结构、T_(3)和促甲状腺激素(TSH)异常率均高于男性(P<0.05);性别(女)、放射工作史、年龄是影响放射工作人员职业健康的危险因素(P<0.05)。结论浙江省内放射工作人员的职业健康状况有待进一步改善,应加强放射工作人员的职业健康管理。

Objective To investigate the current situation of occupational health of radiation workers in Zhejiang Province,China,and to provide a theoretical basis for the improvement of standards and management systems for occupa-tional health examinations of radiation workers.Methods Data of occupational health examination cases were collected from occupational health examination institutions,including basic information,type of physical examination(pre-job,on-job,off-job),and health examination results.The differences in occupational health examination results among different groups were analyzed,and the factors influencing occupational health of radiation workers were analyzed using a logistic re-gression model.Results A total of 5668 cases were collected,with 86%of the participants being male and 14%being fe-male.Compared with the pre-job group,the on-job group showed an increased abnormal rate of triiodothyronine and the off-job group demonstrated an increased abnormal rate of leukocyte count(P<0.05).Compared with the industrial group,the nuclear fuel group showed decreased abnormal rates of thyroid structure and thyroxine and an increased abnormal rate of trii-odothyronine,and the medical group demonstrated an increased abnormal rate of thyroid structure(P<0.05).The abnormal rates of thyroid structure and white blood cell count increased with the increase of working age(P<0.05).The abnormal rates of white blood cell count,thyroid structure,triiodothyronine,and thyroid stimulating hormone were higher in female ra-diation workers than in male radiation workers(P<0.05).Sex(female),radiation work history,and age were the risk factors affecting the occupational health of radiation workers(P<0.05).Conclusion The occupational health status of radiologic-al workers in Zhejiang Province needs to be further improved,and the occupational health management of radiological work-ers should be strengthened.
