Abstract:
OBJECTIVE: To understand the distribution characteristics of new silicosis cases in Inner Mongolia from 2006 to 2018.METHODS: Through the Pneumoconiosis Report Card of Occupational Disease and Occupational Health Monitoring Information System, a subsystem of China Disease Prevention and Control Information System, the data of new cases of silicosis reported in Inner Mongolia from 2006 to 2018 were collected and analyzed by routine data analytic method. RESULTS: A total of 903 new cases of silicosis were reported in this area from 2006 to 2018. Most of the cases are in males that account for 98.8%(892/903). Among them, there were 536 cases of silicosis stage Ⅰ, 259 cases of silicosis stage Ⅱand 108 cases of silicosis stage Ⅲ. The median age of onset was 48 years old and the median length of service for dust exposure was 11.4 years. The industrial distribution was concentrated in nonferrous metal mining and dressing, coal mining and washing, accounting for 66.2% and 9.3% respectively. Private enterprise was the main economic type, accounting for 64.3%. The enterprises were dominated by small-and medium-sized enterprises, accounting for 35.6% and 32.0% respectively. The main types of work were rock driller and hauler, accounting for 39.4% and 17.1% respectively. The geographical distribution was dominated by Chifeng City, Bayannaoer City and Baotou City, accounting for 53.7%, 14.1% and 13.5% respectively. CONCLUSION: In order to better protect the occupational health of workers, it is necessary to strengthen the dust exposure control and protection of non-ferrous metal mining, coal mining and washing industries, private enterprises, and small-and medium-sized enterprises, rock drills and transport workers in Chifeng, Bayannaoer and Baotou Cities.
