Objective To analyze the disease burden caused by occupational coal workers' pneumoconiosis (CWP) in Anhui Methods Province. A total of 1 649 patients with occupational CWP diagnosed in Anhui Province from 1950 to 2019 were selected as the study subjects using a retrospective study method. Age, gender, survival time, location, working age of disease onset, age of death, stage and date of diagnosis of CWP, comorbidities at the time of investigation, hospitalization and outpatient expenses in the past year, cost of absence from work, cost of absence from work of caregivers, and cost of nutrition and transportation were investigated. The years of life lost, years lived with disability (YLDs), disability adjusted life years (DALYs) Results and economic losses were calculated. Among these patients, 1 405 cases survived and 244 cases died. In the age range - - - of 20.0 70.0 years, the YLDs of surviving patients were 2.12 22.20 (8.19±3.59) person years. The YLDs of patients with disease vs - P complications was higher than that of patients without complications [(8.55±3.95) (7.87±3.21) person years, <0.01]. The total - - DALYs of the patients was 14 031.59 person years, and the average per capita DALYs was 8.51 person years. Its YLDs accounted for 82.0 % of the total DALYs. The total economic loss caused by CWP in the 1 405 surviving patients was 354.903 0 Conclusion million yuan, and the average per capita economic loss was 252 600 yuan. The disease burden caused by CWP is relatively high in Anhui Province. In addition to early detection, diagnosis and treatment, it is necessary to focus on prevention and treatment of CWP complications to reduce the disease burden.

Objective To learn of the epidemiological characteristics of pesticide poisoning in western Anhui Province, and to provide the basis for control and prevention. Methods The pesticide poisoning report cards in western Anhui Province during 2006-2016 were collected from Occupational Disease and Occupational Health Information Monitoring System. Descriptive analysis was conducted on the general situation of pesticide poisoning, the distribution of three cases and the types of pesticide poisoning. Results There were totally 2993 cases with pesticide poisoning in western Anhui Province from 2006 to 2016, of which 280 cases (9.36％) were industrial poisoning and 2713 cases (90.64％) were non-industrial poisoning. The average annual incidence rate was 4.63/10000, and showed an increasing trend year by year (P<0.01) . One hundred cases died due to pesticide poisoning, and the fatality rate was 3.34％. Both the industrial and non-industrial poisoning cases were the highest in the third quarter (from July to September), accounting for 78.21％ and 28.86％ respectively. The cases of industrial poisoning were mainly distributed in 45-<55 years old group, and the non-industrial poisoning cases were mainly distributed in 35-<45 years old, accounting for 29.64％ and 20.94％ respectively. The number of cases of industrial poisoning and non-industrial poisoning was 2.33:1 and 1:1.57 respectively. The types of pesticide poisoning involve seven kinds of insecticides, fungicides and rodenticide, and organic phosphorus poisoning was accounted for 30.84％. The highest mortality rate of pesticide poisoning was bisultap (10.93％) . Conclusion The non-industrial pesticide poisoning is the main type in western Anhui Province of pesticide poisoning, and organ phosphorus insecticides are the main types of pesticide poisoning.
