Abstract:

Objective To understand the current status and incidence characteristics of key occupational diseases in Shaowu City in 2024,aiming to improve the monitoring and risk warning capabilities for occupational diseases in Shaowu City,and provide reference for formulating measures to prevent and control occupational diseases. Methods Collect the case information from occupational health examinations conducted in Shaowu City in 2024,and analyze the results of special indicator examinations for occupational populations from different dimensions(gender,age,length of service,enterprise size,industry type,and economic type). Results In 2024,a total of 9 933 people in Shaowu City underwent occupational health examinations,involving 133 enterprises with occupational disease hazards,and 2 cases of suspected occupational diseases were detected. The detection rates of occupational contraindications before the job and during the job were 4.56%(159/3 490) and 1.06%(65/6 110),respectively. The abnormal detection rates of chest radiographs of workers exposed to silicon dust and welding smoke were 1.02% and 0.42%,respectively. No pneumoconiosis changes were detected in other dust positions. The abnormal rates of lung function examination were 7.28% for coal dust,12.61% for silicon dust,12.07% for activated carbon dust,6.94% for welding smoke,and 13.42% for other dust,respectively. Abnormal special indicators were more common in males,particularly in the age group of 49-<59 years and the dust exposure group with 10-<20 years of service. The hazards of silica dust were more prevalent in the mining industry,while other dust hazards were mainly concentrated in the manufacturing industry,with small and medium-sized enterprises being the mainstay. The average abnormal rate of high-frequency hearing threshold in both ears of workers exposed to noise was 12.64%. The highest abnormal rate was observed in the mining industry(57.41%),with small enterprises(17.51%) and joint-stock enterprises(16.67%) showing higher abnormal rates than other types of enterprises,and the differences were statistically significant (all P<0.05). In addition,the abnormality rate among males(14.59%) was significantly higher than that among females(7.07%),and there was a trend of increasing abnormality rate with age and length of service. The abnormal rates of white blood cell,neutrophil and platelet counts in workers exposed to benzene were 6.20%,4.30%,and 0.24%,respectively. The abnormal rates of white blood cell and neutrophil in women were higher than those in men(χ2WBC=16.866,P<0.01;χ2N==5.220,P<0.05). Conclusion Dust and noise are the greatest hazard factors for occupational health risks in Shaowu City. Occupational disease prevention and control should be continued to be strengthened and occupational health knowledge should be publicized among key groups,key industries,and small and medium-sized enterprises.
