武进区制造业噪声作业人员高频听力损失及影响因素分析

Objective To analyze high-frequency hearing loss among manufacturing workers solely exposed to noise in Wujin District, Changzhou City, providing reference data for occupational disease prevention and control. Methods Medical examination records of manufacturing workers solely exposed to noise in Wujin District, Changzhou City, reported by occupational health examination institutions in 2024 were collected. Statistical analysis was performed using SPSS 27.0 software. Results In 2024, occupational health examination data were available for 14,232 workers in noiseexposed manufacturing roles in Wujin District. The detection rate of high-frequency hearing loss was 7.90%. Multivariate Logistic regression analysis indicated that male gender, employment in domestic enterprises, employment in foreign-funded enterprises, age groups 30-<40, 40-<50, and ≥50 years, and employment in the general equipment manufacturing and metal products industries were risk factors for high-frequency hearing loss. ≥50 years old, general equipment manufacturing, and metal products manufacturing were all risk factors for high-frequency hearing loss. Conclusion priority attention should be given to males, individuals aged ≥30 years, domestic enterprises, foreign-funded enterprises, and those working in general equipment manufacturing and metal products manufacturing. The awareness and implementation capabilities of management personnel regarding laws and regulations on occupational disease prevention should be enhanced through intensified publicity of occupational safety knowledge and routine supervision and inspection efforts.
