ABSTRACT
OBJECTIVE: To explore the correlation between the cognition on hearing protection and mental health status of noise-exposed workers. METHODS: A total of 499 noise-exposed workers from 3 enterprises of coal mine, steel and textile in Xinjiang region were selected as study subjects by stratified cluster random sampling method. The cognitive status of hearing protection and mental health status of each group were investigated by the Workplace Health Promotion Pilot Project Questionnaire. RESULTS: A total of 235 workers had abnormal mental health status.The abnormal rate of mental health status was 47.1%(235/499). The results of logistic regression analysis showed that female, age ≤40.0 years, unable to bear current noise hazards, worried about noise-induced-deafness and noise-induced discomfort were the risk factors of abnormality of mental health status(odds ratio values were 1.62, 1.87, 2.42, 2.20, 2.14, P<0.05). Using hearing protectors for ≥3.0 years was the protective factor of abnormality of mental health status(odds ratio value was 0.47, P<0.05). CONCLUSION: The subjective cognition on hearing protection has an impact on the mental health of noise-exposed workers.
