Analysis of the results of hearing screening in physical examination in Beijing / 中华健康管理学杂志

ABSTRACT

Objective:To investigate the prevalence and characteristics of adult hearing loss.Methods:From March 2018 to November 2019, 8, 439 adult physical examinees were screened for hearing (i.e., 500 Hz, 1000 Hz, 2000 Hz, and 4000 Hz pure tone air conduction audiometry), while some were examined for hearing diagnosis (i.e., 250 Hz, 500 Hz, 1, 000 Hz, 2, 000 Hz, 4 000 Hz, and 8 000 Hz pure tone bone air conduction audiometry). Prevalence, location, frequency and type of hearing loss in different age and gender groups were analyzed using SPSS 25.0.Results:The prevalence of hearing loss was 32.2%, which increased with age. The prevalence in males was higher than that of females (40.1% vs. 21.6%). The rate of single frequency damage was higher in male than in female, while the rate of multiple frequency damage was higher in women than in men ( P<0.001). The high frequency (4 000 Hz) damage rate in male was higher than that of females, while the low-middle frequency (500-2 000 Hz) damage rate in females was higher than that of males ( P<0.001). Sensorineural hearing loss accounted for 90.8%, while conductive hearing loss was 3.9%, mixed hearing loss was 5.0%, and others were 0.3%. Conductive hearing loss was mainly concentrated in the younger age group. Conclusion:Physical examination population has a relatively high prevalence of hearing loss. The characteristics of hearing loss differed with age and gender.
