Abstract:

Objective To analyze the burden of pneumoconiosis in a district of Beijing,and to provide reference for the prevention and control of pneumoconiosis. Methods The data of pneumoconiosis cases from 2003 to 2023 were collected from the Occupational Disease and Health Hazard Monitoring Information System. The disease burden was analyzed by disability-adjusted life year(DALY),years of life lost with premature death(YLL) and years of lived with disability(YLD). Results Among the 161 cases of pneumoconiosis in a district of Beijing,154 were male,with an average age of (67.51±10.17)years,and 7 were female,with an average age of (80.29±10.86)years. The cumulative DALY loss was 583.80 person-years,and the MQR) was 3.04(3.12) years. The cumulative YLD loss was 487.39 person-years,accounting for 83.49%. The cumulative YLL loss of 96.41 person-years,accounted for 16.51%. There were statistically significant differences in DALY among different diagnostic ages,diagnostic stages,disability grades,course of disease and date of diagnosis(H=45.034,32.613,68.024,47.561,66.285,all P<0.01). The age of pneumoconiosis cases,the type of pneumoconiosis,the course of disease,the grade of disability,and the date of diagnosis were the influencing factors of pneumoconiosis disease burden(β=-0.408,-0.163,0.273,-0.215,-0.618,-0.338,-0.438,all P<0.05). Conclusion The disease burden of pneumoconiosis in a district of Beijing shows a fluctuating trend. The disease burden is mainly caused by the disability caused by pneumoconiosis. It is necessary to strengthen the control of dust hazards in industries and enterprises,strengthen the occupational health protection of workers in dust posts,and reduce the disease burden of patients.
