Abstract:Objective To investigate the incidence, incidence characteristics and trend of pneumoconiosis in Shangqiu City so as to provide a basis for formulating pneumoconiosis prevention and treatment strategies. Methods According to the relevant information about pneumoconiosis patients diagnosed and reported in 1969-2019 provided by Henan Occupational Disease Prevention and Control Institute, we obtained the work-related injury insurance, survival status, assistance, address and contact information of pneumoconiosis patients from human resources and social security bureau, public security bureau, civil affairsbureau and other departments. Basic data were acquired through the monitoring of death causes of residents, survey on occupational pneumoconiosis during 1969-2019 and the pneumoconiosis reporting system. Through the cooperation of employment units and neighborhood or village committees of pneumoconiosis patients, the reported patients with occupational pneumoconiosis were followed up with a telephone or door-to-door interview, and the relevant information were investigated and obtained. Results There were 316 patients with pneumoconiosis in Shangqiu City from 1969 to 2019, of whom 172 survived and 144 died. There were 9 types of pneumoconiosis, and silicosis was the most common type, followed by asbestosis and coal workers' pneumoconiosis. Most of the pneumoconiosis patients were from Yongcheng City, followed by Liangyuan District. There were 274 stage Ι pneumoconiosis patients(with 123 death cases), 38 stage II pneumoconiosis patients (with 20 death cases), and 4 stage Ш pneumoconiosis patients (with 1 death case). The male-to-female sex ratio of the pneumoconiosis patients was 2.5:1. The onset age mainly ranged from 40 to 49 years, and the working age of exposure to dust mainly ranged from 15 to 29 years. The 316 pneumoconiosis patients were distributed in 25 different industries, and mainly concentrated in the non-metallic mineral products industry (37.97%, 120/316), the coal mining and washing industry (30.38% 96/316), and thermal power plants (8.54%, 27/316). Among 172 prevalent cases, there were 71 (41.28%) cases enjoyed work-related injury insurance, 80 (46.51%) cases with employers' compensation, 160 (93.02%) cases with basic medical insurance for urban and rural residents, 35 (20.35%) cases with serious disease insurance, and 1 (0.58%) case with other medical assistance and poverty relief. All the prevalent cases did not receive the basic living allowance. Conclusion Pneumoconiosis prevention and treatment work in Shangqiu City is still facing a severe situation. Prevention and control work should focus on non-metallic mineral products industry, coal mining and washing industry, power, heat, gas and water production and supply industries, and the types of pneumoconiosis prevention and control mainly include silicosis, asbestosis and coal workers' pneumoconiosis.
