微信干预对工人听力防护和认知的影响

Effects of Wechat intervention on hearing Protection and Cognition of Workers

目的 探讨微信干预可否提高噪声作业工人听力防护认知水平。方法 选取2019年3月至2019年6月期间在佛山市第一人民医院禅城医院进行噪声职业健康检查工人为研究对象,干预时间为1年,微信干预组开展包括随访、微信文章推送、自我APP听力测听和作业场所噪声检测,对照组进行常规干预;研究对象均进行干预前后电测听检查、听力防护知识和听力防护行为问卷。结果 共有344名参与者(干预组,n=175;对照组,n=169)纳入分析。听力防护知识干预后与干预前差值微信干预组明显高于对照组,微信干预组听力自我保护能力明显优于对照,微信干预组听力损失低于对照组(双耳高频平均听阈1.07±1.35 VS 4.08±1.81dBHL,双耳语频平均听阈0.95±1.10 VS 2.10±1.1 dBHL)差异具有统计学意义,(P<0.001)。结论 微信干预可提高听力防护认知和提高自我保护能力,减少听力损失发生。

Objective To explore whether Wechat follow-up can improve the cognitive level of hearing protection in workers exposed to noise.Methods Workers who underwent noise occupational health examination in Chancheng Hospital of Foshan first people’s Hospital from March 2019 to June 2019 were selected and intervened for one year.Wechat intervention group carried out follow-up,Wechat article push,self-APP audiometry and workplace noise detection,while the control group received routine intervention.The subjects were given electric audiometry,hearing protection knowledge and hearing protection behavior questionnaire before and after intervention.Results A total of 344 participants (intervention group,nasty 175;control group,nasty 169) were included in the analysis.The difference of hearing protection knowledge after and before intervention in the Wechat group was significantly higher than that in the control group,and the hearing self-protection ability in the Wechat group was significantly better than that in the control group.The hearing loss in the Wechat group was lower than that in the control group (binaural high frequency average hearing threshold 1.07±1.35 VS 4.08±1.81 dBHL,binaural speech frequency average hearing threshold 0.95±1.10 VS 2.10±1.1 dBHL).The difference was statistically significant,(P<0.001).Conclusion Wechat follow-up intervention can improve the cognition of hearing protection and the ability of self-protection,and reduce the incidence of hearing loss.
