Epidemiological analysis of newly diagnosed occupational pneumoconiosis in Guangxi Zhuang Autonomous Region from 2013 to 2022
Objective To analyze the epidemiological distribution of new occupational pneumoconiosis(hereinafter referred to as"pneumoconiosis")in Guangxi Zhuang Autonomous Region from 2013 to 2022.Methods Data of newly diagnosed pneumoconiosis cases reported in Guangxi Zhuang Autonomous Region from 2013 to 2022 were collected,and epidemiological characteristics were analyzed using descriptive analysis method.Results A total of 972 newly diagnosed pneumoconiosis cases were reported in Guangxi Zhuang Autonomous Region from 2013 to 2022.Except for mica pneumoconiosis,12 other types of pneumoconiosis were reported.Most of the cases were males,accounting for 97.0%.The diagnosis age of the cases of 40-<60 years old accounted for 77.4%,and the dust exposure age<30 years of the cases accounted for 96.4%.Silicosis was the most common type of pneumoconiosis,followed by coal workers' pneumoconiosis,accounting for 64.6%and 27.9%,respectively.The cases of stage Ⅰ,Ⅱ and Ⅲ pneumoconiosis accounted for 77.7%,14.9%and 7.4%,respectively.The regional distribution was mostly in Hechi City,accounting for 51.9%.Industry distribution was more common in non-ferrous metal mining,coal mining and washing industry,accounting for 64.9%in total.Most cases were reported in private enterprises and small to medium-sized enterprises,accounting for 53.7%and 76.6%respectively.The most common occupations were coal miners and drillers,accounting for 47.7%in total.Conclusion Newly diagnosed pneumoconiosis cases in Guangxi Zhuang Autonomous Region show certain clustering characteristics in terms of disease type,region,enterprise characteristics,and occupation distribution.The prevention and treatment of pneumoconiosis in small and medium-sized private enterprises in key areas and key industries should be strengthened,especially for workers over 40 years old and with less than 30 years of dust exposure.
