Abstract:
Objective:To explore the effect of the combined effect of noise and heat on occupational hearing loss of workers by using Meta-analysis method.Methods:In August 2020, the Chinese and English literature on the relationship between exposure to noise and heat and occupational hearing loss published from January 2005 to August 2020 by CNKI, China Biomedical Literature Service System, Wanfang Data Knowledge Service Platform, VIP Official Database, Medline and PubMed Databases were searched, using noise, heat or hyperthermia, hearing as keywords. The selected data were analyzed by Stata 12.0 software, and the combined OR (95% CI) value included in the literature was calculated. Sensitivity analysis was used to explore the source of heterogeneity and analyze publication bias. Results:A total of 14 literatures (14 in Chinese, 0 in English) were included in the analysis, and 38654 subjects were included, including 6411 workers in the noise and heat combined effect group and 32243 workers in the noise alone group. The probability of hearing loss in the noise and heat combined effect group was 1.39 times higher than that in the noise alone group (95% CI: 1.14-1.69). The effect size OR was stable after sensitivity analysis, and there was no publication bias in the included literatures tested by Egger's and Begg's Method ( z=0.38, P=0.702, t=-0.74, P=0.476) . Conclusion:Simultaneous exposure to noise and heat may increase the risk of hearing loss for workers in noisy workplaces.
