[Analysis of disease burden of welder's pneumoconiosis in Jiangsu Province].

To investigate the current status of disease burden and its influencing factors among welder's pneumoconiosis patients, and provide scientific basis for taking targeted intervention measures. From June 2022 to June 2023, the patients with welder's pneumoconiosis in Jiangsu Province were selected from 1956 to 2020 as the research objects, and disability adjusted life years (DALY) were used as the comprehensive index to study the disease burden. The direct and indirect economic losses caused by the diseases were calculated, and the factors affecting the disease burden were discussed by multiple linear regression method. A total of 974 cases of welder's pneumoconiosis were reported in Jiangsu Province, the cumulative loss of DALY was 6300.73 person-years, and the per capita loss was 6.47 person-years. Among them, the healthy life years lost due to disability (YLD) was 6156.50 person-years (97.71%) , and the healthy life years lost due to premature death (YLL) was 144.23 person-years (2.29%) . Multiple linear regression analysis showed that the main factors affecting DALY were disability grade, diagnostic age, pneumoconiosis grade and length of dust exposure (<0.05) . The total economic loss caused by 974 welder's pneumoconiosis patients was 1831838160.18 yuan, and the per capita loss was 1880737.33 yuan. Among them, the direct economic loss was 970917563.75 yuan (53.00%) , and the indirect economic loss was 860920596.43 yuan (47.00%) . Welder's pneumoconiosis causes serious disease burden to patients, and at the same time causes huge economic losses to individuals and society, which seriously hinders the development of society. Taking effective control measures to prevent the incidence of welder's pneumoconiosis is the key to reduce the disease burden.
