Abstract:
Objective:To analyze the epidemiological characteristics and the harmfulness situation of pneumoconiosis notified in Chongqing from 2011 to 2015, so as to provide scientific basis for prevention and control of pneumoconiosis.
Methods:The Chongqing database of new cases of pneumoconiosis reported from 2011 to 2015 was subjected to systematic arrangement. SPSS 18.0 was adopted for statistical description and trend test.
Results:From 2011 to 2015 a total of 24903 new cases of pneumoconiosis were diagnosed, including I (16 294 cases, 65.43%), II (6 520 cases, 26.18%), III (2 089 cases, 8.39%). Of all patients, 98.93% were cases of coal-workers' pneumoconiosis and silicosis. 13 383 (53.74%) were coal-workers' pneumoconiosis cases, and 11 253 (45.19%) were silicosis cases. The pneumoconiosis cases were distributed mainly in Fengjie County (3 329 cases, 13.37%), Yongchuan District (2 849 cases, 11.44%), and Chengkou County (2 584 cases, 10.38%). Most cases were centered in mining industry (17 575 cases, 70.57%) and construction industry (6 613 cases, 26.56%). The median lengths of service at the onsets of new cases of pneumoconiosis, silicosis, coal-workers' pneumoconiosis were 7.0, 3.0, and 16.0 years, respectively. The median age at the onset of pneumoconiosis was shortened from 2011 to 2015. The median ages at the onsets of new cases of pneumoconiosis, silicosis, coal-workers' pneumoconiosis were 53.0, 62.0, and 49.0 years, respectively.
Conclusion:The research results showed obvious diseases, regions and industries distribution. The median length of service at the onset of pneumoconiosis was on the low side, and a shortening trend showed in age at the onset of pneumoconiosis. Based on the epidemiological characteristics of pneumoconiosis, the prevention and control of pneumoconiosis should be enhanced in key industries such as mining industry and construction industry.
