Abstract:
Objective To analyze the status and its influencing factors of high-frequency hearing loss (HFHL) among occupational noise-exposed workers. Methods A total of 6 764 noise-exposed workers who participated in occupational medical examinations during their employment were selected as the study subjects using the judgmental sampling method. Their pure-tone audiometry results were analyzed. Results The detection rate of HFHL among the study subjects was 10.3%. Binary logistic regression analysis result revealed that males had a higher risk of HFHL than females (P<0.05). The HFHL risk of workers increased with age (all P<0.01). Workers with longer noise exposure durations had a higher risk of HFHL (all P<0.01). Smokers had a higher detection rate of HFHL than non-smokers (P<0.01). Workers in the mining industry, electricity/heat/gas and water production and supply industry, and other industries had a higher HFHL detection rate compared with manufacturing workers (all P<0.05). Medium-sized enterprise workers had a lower HFHL detection rate compared with micro-sized enterprise workers (P<0.05), while workers in private enterprises had a higher HFHL detection rate compared with those in state-owned enterprises (P<0.05). Workers who exposed to noise combined with dust, lead, high temperature, or multiple factors had a higher HFHL risk than those only exposed to noise (all P<0.05). Conclusion Gender, age, noise exposure duration, smoking, industry, and exposure to noise combined with other occupational hazard factors are all influencing factors for HFHL among noise-exposed workers. Targeted occupational health education on noise hazard prevention and occupational medical surveillance should be strengthened for key populations in priority industries, including male workers, older employees, individuals with prolonged noise exposure, smokers, and those concurrently exposed to noise and one of the following: dust, lead, high temperatures, or multiple occupational factors.
