Objective: To understand the current situation of high-frequency hearing loss of workers exposed to occupational noise in Hubei Province and its multi-level influencing factors. Methods: In June 2021, the basic information, occupational history, physical examination results and other relevant information in the "Occupational Health Examinations Case Cards" for noise workers in Hubei Province in 2020 were extracted from the subsystem of the "China Disease Prevention and Control Information System". Multilevel level of logistic model was used to analyze the related factors of high-frequency hearing loss of noise-exposed workers. Results: In 2020, the incidence rate of occupational high-frequency hearing loss in Hubei Province was 8.25% (6450/78152), and the incidence rate in various regions of the province ranged from 1.13% to 19.87%. At the individual level, male, ≥ 30 years of age, 6-10 years of service, small and micro enterprises, as well as construction, mining, manufacturing, transportation and rental services were the risk factors for high-frequency hearing loss (P<0.05). The risk of high-frequency hearing loss among workers in foreign-funded enterprises was significantly lower than that of workers in state-owned/collective enterprises (P<0.05). At the regional level, the younger the age of the employees, the lower the risk of high-frequency hearing loss (P<0.05). There was no significant correlation between the regional economic level and the risk of high-frequency hearing loss (P>0.05) . Conclusion: The incidence rate of occupational high-frequency hearing loss in Hubei Province is low in 2020, but the incidence rate varies greatly in different regions of the province, mainly due to differences in employment age, while the development of regional economic level has not reduced the risk of occupational high-frequency hearing loss.
目的： 了解湖北省职业性噪声作业工人高频听力损失的现状及多层次的影响因素。 方法： 于2021年6月，从"中国疾病预防控制信息系统"子系统提取湖北省2020年噪声作业工人职业健康检查个案卡中的基本信息、职业史、体检结果等相关资料。采用多水平logistic回归模型对职业性高频听力损失的多层次因素进行分析。 结果： 2020年湖北省职业性高频听力损失发生率为8.25%（6 450/78 152），省内各地区发生率范围为1.13%~19.87%。个体层面，男性、年龄≥30岁、工龄6~10年、小微型企业，以及建筑业、采矿业、制造业、交通运输业和租赁服务业是发生高频听力损失的危险因素（P<0.05），外资企业工人高频听力损失发生风险明显低于国有/集体企业工人（P<0.05）。地区层面，地区用工年龄越年轻，高频听力损失发生风险越低（P<0.05）；地区经济水平与高频听力损失发生风险关联无统计学意义（P>0.05）。 结论： 2020年湖北省职业性高频听力损失发生率低，但省内各地区发生率差异较大，主要原因是用工年龄的差异，而地区经济水平发展没有降低职业性高频听力损失的发生风险。.
