Abstract:
Objective - ( )
To analyze the epidemiological characteristics of occupational noise induced deafness ONID
( )
diagnosed by Guangdong Province Hospital of Occupational Disease Prevention and Control GDHOD from 2016 to 2020 and
- Methods
the reasons non ONID diagnosis. The data of ONID patients diagnosed in GDHOD from 2016 to 2020 were collected
“
from the Occupational Disease Report Card in the Occupational Disease and Occupational Health Information Monitoring
” “ ” -
System subsystem of the China Disease Prevention and Control Information System . The data of non ONID subjects were
,
collected from the occupational disease diagnosis archives in the same hospital and the relevant data were analyzed
Results , , ( )
retrospectively. Of the 1 432 subjects 824 subjects were diagnosed as ONID patients mainly of mild ONID 86.0% .
(M) , M
Male patients accounted for 88.0%. The median of diagnosis age was 45.0 years old and of length of employment of
, , ,
diagnosis was 8.3 years. ONID patients were mainly found in Zhongshan Dongguan Zhuhai Jiangmen and Guangzhou City in

the Pearl River Delta accounting for 67.6%. The cases distributed in 519 enterprises mainly on manufacturing 90.2% .

Among the 139 enterprises each enterprise had 2 11 patients worked within five years accounting for 53.9% 91.1% of the

ONID patients were distributed in large medium and small enterprises. ONID patients mainly worked in non public
enterprises that accounted for 91.3%. There were 606 subjects could not be diagnosed as ONID. The main reasons for not being

diagnosed were that the weighted value of better ear hearing threshold was less than 26 dB 34.8% the working history of

occupational noise exposure was less than three years 31.5% the weighted value of better ear hearing threshold was less thanConclusion
26 dB and the average hearing threshold of binaural high frequency was less than 40 dB 16.2% . The ONID

the working history of occupational noise exposure was less than three years the weighted value of better ear hearing threshold
