目的了解连云港市尘肺病的发病状况及流行特征,做好尘肺病的预防工作。方法采用流行病学方法,对连云港市2003—2008年新诊断尘肺病资料进行统计分析。结果新诊断尘肺病138例,分布于10个行业系统,Ⅰ期108人,Ⅱ期28例,Ⅲ期2例,分别占78.26%、20.29%、1.45%。2003年诊断尘肺病例的平均发病工龄明显长于2007、2008年诊断病例,差异有统计学意义(P<0.01)。尘肺病例中接尘工龄小于或等于5年的有35例,其中Ⅰ期、Ⅱ期各有17人,Ⅲ期1人,其中Ⅱ期、Ⅲ期主要来自私营企业,诊断于2007—2008年。结论近年来一些私营企业粉尘危害十分严重,尘肺发病的工龄越发缩短、病情越发严重。应加强尘肺病的防治工作。
Objective To understand the incidence and epidemic characteristics of pneumoconiosis in Lianyungang City and to make the pneumoconiosis prevention work well. Methods Epidemiological methods were used to analyze the data of newly diagnosed pneumoconiosis in Lianyungang from 2003 to 2008. Results 138 cases of newly diagnosed pneumoconiosis were found in 10 industry systems, including 108 in stage Ⅰ, 28 in stage Ⅱ and 2 in stage Ⅲ, accounting for 78.26%, 20.29% and 1.45% respectively. The average length of service for diagnosing pneumoconiosis in 2003 was significantly longer than that in 2007 and 2008, with a significant difference (P <0.01). In the pneumoconiosis cases, 35 cases were exposed to dust less than or equal to 5 years, of which 17 cases were in stages Ⅰ and Ⅱ, and 1 was in stage Ⅲ. The patients in stage Ⅱ and Ⅲ were mainly from private enterprises, diagnosed in 2007-2008. Conclusion In recent years, the dust of some private enterprises is seriously endangered. The length of service of pneumoconiosis has been shortened and the condition has become more and more serious. Pneumoconiosis prevention and treatment should be strengthened.
