2006-2011年四川省尘肺发病特征

New Pneumoconiosis Cases in Sichuan,2006-2011

目的分析四川省尘肺发病特征和趋势,为职业病防治工作提供科学依据。方法通过四川省职业病网络报告系统收集2006-2011年新发尘肺病例资料,分析尘肺发病年龄、接尘工龄、分布地区、行业和机构来源等。结果 2006-2011年,四川省共报告新发尘肺15 671例,其中矽肺占62.5%。报告尘肺病例前3位行业为煤炭、铁道和建设,分别报告7 278、4 032和1 749例,煤炭行业的尘肺新发病例数占46.4%,新发尘肺平均发病年龄(56.8±10.4)岁、接尘工龄平均为(10.3±10.2)年,且Ⅱ期、Ⅲ期尘肺比例逐年增加。80.8%新发尘肺来自诊断机构的报告。结论四川省尘肺患者数量较多,以矽肺为主,主要集中在煤炭行业,发病年轻化,接尘工龄较短。

Objective To analyze the characteristics of pneumoconiosis cases in Sichuan province and to provide a scientific basis for the prevention of occupational diseases.Methods The data of new pneumoconiosis cases were collected from national surveillance system of occupational disease in Sichuan province during 2006-2011 and were statistically analyzed.Results During 2006-2011,altogether 15 671 new pneumoconiosis cases were reported,and 62.5% of them were silicosis.The top three enterprises with high-incidence of pneumoconiosis cases were coal（ 7 278）,railway（ 4 032） and construction enterprise（ 1 749）.The average age of diagnosis for new pneumoconiosis was 56.8 ±10.4 years old,and the average of exposure duration was 10.3 ±10.2 years.The proportions of new pneumoconiosis with phase Ⅱ and Ⅲ increased yearly.A proportion of 80.8% pneumoconiosis cases were reported from diagnosis agencies.Conclusion The prevalence rate of pneumoconiosis cases in Sichuan province is relatively high;mostly silicosis and were distributed in coal enterprise.New pneumoconiosis cases are becoming younger than before and the exposure duration is shorter as well.
