摘要目的:分析噪声作业工人个人防护用品（personal protective equipment，PPE）正确使用情况及其影响因素，为开展噪声干预提供参考信息。方法:于2023年9月，采用分层抽样的方法，根据2022年广东省各地市国内生产总值排名，将21个地级市分为经济发达组和经济欠发达组，各组随机选择2个城市，每个城市随机选择16~17家企业作为研究现场，每家企业纳入20人作为研究对象。共发放、回收问卷1 200份，有效问卷1 099份，有效回收率为91.6%。按照GB/T 23466-2009《护听器的选择指南》评价工人佩戴护听器是否正确并测量工人佩戴护听器的个人声衰减值，使用自行设计的《噪声作业工人护听器使用情况调查表》调查其PPE使用相关情况，采用多因素logistic回归分析其PPE正确使用的影响因素。结果:429名（39.0%）噪声作业工人在工作中能够正确使用PPE。多因素logistic回归分析结果显示，年龄、工作时长、性别、职业性噪声防护知识得分、使用PPE是否检查、工友督促使用PPE频率均是有效使用PPE的影响因素（ P<0.05）。 结论:噪声作业工人正确使用PPE状况仍需改善，应提升企业职业健康教育水平，促进噪声作业工人正确使用PPE。

abstractsObjective:To analyze the correct use of personal protective equipment (PPE) among noise-exposed workers and its influencing factors, providing reference information for noise intervention efforts.Methods:In September 2023, a stratified sampling method was employed. Based on the 2022 gross domestic product (GDP) rankings of cities in Guangdong Province, 21 prefecture-level cities were divided into economically developed and less developed groups. Two cities were randomly selected from each group, and 16 to 17 enterprises were randomly chosen from each city as study sites. Twenty workers were included from each enterprise as study subjects. A total of 1200 questionnaires were distributed and collected, and 1099 were valid, with an effective recovery rate of 91.6%. The correctness of hearing protector usage was evaluated according to the GB/T 23466-2009 "Guidelines for the Selection of Hearing Protectors", and the personal attenuation rating values of the workers' hearing protectors were measured. A self-designed Questionnaire on the Use of Hearing Protectors by Noise-Exposed Workers was used to investigate PPE-related usage. Multivariate logistic regression analysis was conducted to identify factors influencing the correct use of PPE.Results:A total of 429 (39.0%) noise-exposed workers were able to use PPE correctly during work. Multivariate logistic regression analysis showed that age, working hours, gender, occupational noise protection knowledge score, whether PPE was checked after use, and the frequency of peer supervision on PPE usage were significant factors influencing the effective use of PPE ( P<0.05) . Conclusion:The correct use of PPE by noise-exposed workers still needs to be improved. The level of occupational health education in enterprises should be enhanced to promote the correct use of PPE by noise-exposed workers.
