[The relationship between type Ⅱ diabetes mellitus and hearing loss：a Meta-analysi].

Objective:Analysis of the relationship between type 2 diabetes and hearing loss through the available literature.Method:According to the main keyword retrieval databases at home and abroad,and in accordance with the inclusion and exclusion criteria for the literature,the listening incidence rate,OR value,the frequency of pure tone hearing threshold,tests the average standard deviation were chose as the evaluation index. Meta analysis was carried out using Rev Man5.3 software. Result:According to the inclusion and exclusion criteria,the articles were screened and included in the final to meet the requirements of the 17 studies. The prevalence of hearing loss in patients with type II diabetes mellitus was 21.0%-74.6%,which was 2.54 times higher than the control group. The difference was statistically significant between the two groups(OR=2.54,95% CI 1.85-3.49,P<0.000 01). In addition,the hearing threshold of all frequencies in type Ⅱ diabetes group was higher than that of control group(Z=5.03,P<0.000 01). Conclusion:Type 2 diabetes can affect hearing loss,especially at the high frequencies.
