Abstract:
Objective: To analyze the epidemiological distribution of new occupational pneumoconiosis (hereinafter referred as pneumoconiosis) in Henan Province from 2006 to 2020. Methods: Clinical data of newly recruited pneumoconiosis cases from 2006 to 2020 in Henan Province were retrospectively analyzed. Results: A total of 9 624 cases of newly diagnosed pneumoconiosis were reported in Henan Province in the past 15 years, of which 98.6% were males. The number of cases had two peaks, one in 2009-2011 and the other in 2014-2017. There were 12 types of pneumoconiosis of all reported cases except for mica pneumoconiosis, in which coal workers' pneumoconiosis and silicosis accounted for 96.0%. The incidence of phase Ⅰ, Ⅱ and Ⅲ pneumoconiosis was 64.7%, 21.0% and 14.3%, respectively. The incidence of phase Ⅱ and Ⅲ silicosis was higher than that of coal miners' pneumoconiosis (56.3% vs 22.7%, P<0.01). Patients with pneumoconiosis were mainly distributed in Zhengzhou City, Sanmenxia City, Luoyang City, Pingdingshan City and Hebi City, accounting for 85.0%. The enterprises involved were mainly mining industry, large- and medium-sized enterprises, state-owned enterprises and collective enterprises. The top five position of patients were coal miners, rock drillers, excavators, coal mixed workers and pure coal miners, total accounting for 72.0%. There were 196 enterprises reported ≥10 cases, accounting for 17.2% of all enterprises and 80.3% of the total of newly diagnosed pneumoconiosis cases. The median (M) of onset age of new cases was 49 years old, and the M of onset of working age was 16 years. The onset age of silicosis was younger (M: 49 vs 48 years old, P<0.05), while the onset of working age was longer (M: 10 vs 20 years, P<0.05), compared with that of coal workers' pneumoconiosis. Conclusion: The incidence of pneumoconiosis in Henan Province were disease clustering distribution, regional distribution, industry of enterprise, enterprise scale, enterprise type, nature and working position distribution of enterprises. And it showed the characteristics of group incidence. The prevention and control treatment of pneumoconiosis should be strengthened in key areas, key enterprises and key diseases and jobs.
