Analysis of the epidemiological characteristics of new occupational pneumoconiosis in Jiangxi Province, 2010-2019 / 中国职业医学

ABSTRACT

OBJECTIVE: To analyze the epidemiological characteristics of new occupational pneumoconiosis(hereinafter referred to as pneumoconiosis) in Jiangxi Province from 2010 to 2019. METHODS: The data of new pneumoconiosis cases in Jiangxi Province from 2010 to 2019 were collected through the Occupational Disease and Occupational Disease Health Information Monitoring Subsystem in the China Disease Prevention and Control Information System, and a retrospective analysis was conducted. RESULTS: From 2010 to 2019, there were 4 450 new cases of pneumoconiosis in Jiangxi Province. Among these cases, the main disease types were coal workers′ pneumoconiosis and silicosis, accounting for 98.5%. The number of new cases of pneumoconiosis showed a decreasing trend with the increase of years for the last ten years(P<0.05). The median age and the 0 th-100 th percentile [M(P_0-P_(100))] of new-onset pneumoconiosis diagnosis was 56.6(34.0-97.0) years old. The service length M(P_0-P_(100)) with dust-exposure was 12.0(1.0-48.0) years. The main industry of the new pneumoconiosis cases was concentrated in the coal mining and washing industry(63.4%). The distribution of economic types of enterprises with new pneumoconiosis cases was mainly state-owned enterprises(70.0%). The enterprise scale was medium-sized and small enterprises(65.9% in total). The types of work were mainly coal blenders, rock drillers, and coal miners, accounting for 56.5%. CONCLUSION: The incidence of occupational pneumoconiosis in Jiangxi Province is not optimistic. It is necessary to strengthen the prevention and control of occupational diseases on workers exposed to dust in key industries, enterprises and types of work.
