Abstract: Objective To systematically evaluate the effect of occupational noise on electrocardiogram(ECG) of workers in China. Methods Using "noise" and "electrocardiogram" as keywords,the correlation studies on the effect of occupational noise on ECG of Chinese workers published in CNKI,Wanfang,VIP,CBM and Pubmed databases from 2002 to 2021 were searched. Stata MP 16 software was used for meta-analysis. Results A total of 25 of literature were included in this study,with a total of 17 785 cases, 10 083 in the noise-exposed group and 7 702 in the control group. The combined effect size(OR) of abnormal ECG detection rate in noise exposure group and control group was 2.34,95%CI was 2.02-2.69(P<0.05). After the heterogeneity test,six articles with greater heterogeneity were deleted. The results showed that the combined effect size(OR) of abnormal ECG detection rate in noise exposure group and control group was 2.14,95%CI was 1.93-2.37(P<0.05),moreover,the incidence of sinus arrhythmia,conduction abnormalities,cardiac hypertrophy,high voltage,and ST-T changes in the exposure group was higher than that in the control group(P<0.05). Conclusion Noise exposure is the risk factors of abnormal electrocardiogram in workers in China,it is necessary to strengthen the protection of workers' noise exposure and conduct regular health examination.
