Abstract:
Objective:To provide scientific evidence for the prevention and control strategies of noise-induced deafness, to analyze the epidemiological characteristics of the occupational noise-induced deafness diagnostic applicants in Guangzhou city during 2011-2018.Methods:In March 2019, by consulting the occupational disease diagnosis records, we investigated the distribution of all 471 occupational noise-induced deafness diagnostic applicants in Guangzhou Occupational Disease Prevention and Treatment Center from 2011 to 2018. Frequency and constituent ratio were used to describe the distribution.Results:From 2011 to 2018, there were 471 cases of occupational noise-induced deafness diagnostic applicants and 211 of the applicants were diagnosed as occupational noise-induced deafness (44.8%, 211/471) . The new cases were mainly mild (83.9%, 177/211) , with the predilection age of 40.0-49.0 years old (41.7%, 88/211) and the predilection seniority of 5.0-9.9 years (38.9%, 82/211) . Among the new cases, there were mainly males (88.6%, 187/211) . Most of the new cases were distributed in Nansha district (23.2%, 49/211) , Huangpu district (22.7%, 48/211) and Panyu district (21.8%, 46/211) . Besides, in terms of industry distribution, they were concentrated in manufacturing industry (82.0%, 173/211) . The scale of enterprises was mainly medium-sized (42.7%, 90/211) , and the most of their economic type was domestic-funded (40.8%, 86/211) .Conclusion:Although most of the newly diagnosed cases of occupational noise deafness in Guangzhou are mild, they still need to be paid attention to and strengthen the noise industry protection education.
