目的浅析近5年镇江市尘肺发病特点及原因。方法对2006年1月1日—2010年12月31日镇江市新诊断的尘肺患者构成、所属企业性质、发病年龄、接尘工种、工龄等方面进行比较分析。结果近5年来镇江市尘肺检出数、检出率有先升高后下降的趋势。国有企业所占比例逐渐下降,患者平均发病年龄高于非国有企业患者(P<0.01),接尘工龄与非国有企业患者相当。工龄不超过10年的新发尘肺工种以主掘进工、凿岩工和破碎工例数为多。结论国企尘肺防治工作是有成效的,平均发病年龄超过工人退休年龄。非国有企业尘肺发病所占比例升高,新发尘肺发病年龄轻,工龄短,病情重。

Methods From January 1, 2006 to December 31, 2010 Zhenjiang City, the newly diagnosed pneumoconiosis patients, the nature of their business, the age of onset, the type of dust, the length of service for comparative analysis. Results In the past five years, the number of pneumoconiosis detected in Zhenjiang City showed a trend of first increasing and then decreasing. The proportion of state-owned enterprises gradually decreased, and the average age of patients was higher than that of non-state-owned enterprises (P <0.01). The length of service for taking dust was equivalent to that of non-state-owned enterprises. There are a large number of main tunneling workers, rock drillers and crusher workers in new-type pneumoconiosis whose length of service does not exceed 10 years. Conclusions The prevention and treatment of pneumoconiosis in state-owned enterprises is effective, and the average age of onset exceeds the retirement age of workers. The proportion of non-state-owned enterprises in the incidence of pneumoconiosis increased, the incidence of new-onset pneumoconiosis, short working age, serious illness.
