目的了解乐山市尘肺病发生状况,为乐山市尘肺病防治工作提供科学依据。方法依据GBZ70-2002《尘肺病诊断标准》,参照GB5906-2000《尘肺病诊断标准片》,对2005—2007年乐山市新诊断的尘肺病例进行分析。结果2005—2007年新诊断尘肺病415例,其中退休职工326例,占78.55%;平均发病年龄54.21岁,明显高于1949—1998年四川省尘肺病例平均发病年龄(47.88岁);新诊断的尘肺病例中,建材系统仅8例,但其中Ⅱ、Ⅲ期尘肺病例就有6例,占75%,明显高于新诊断尘肺病例36.38%的跨期诊断比例。结论粉尘接触退休工人的职业健康监护同在岗工人一样非常重要,应当严格依法定期进行;乐山市建材系统工人的职业健康监护严重缺失,潜在粉尘危害情况严峻,应加强卫生监督,保障工人的职业健康,使监护权落到实处。
Objective To understand the occurrence of pneumoconiosis in Leshan City and provide a scientific basis for the prevention and control of pneumoconiosis in Leshan City. Methods Based on GBZ70-2002 “pneumoconiosis diagnostic criteria” and referring to GB5906-2000 “pneumoconiosis diagnostic criteria”, the newly diagnosed cases of pneumoconiosis in Leshan City from 2005 to 2007 were analyzed. Results A total of 415 newly diagnosed pneumoconiosis cases were recruited from 2005 to 2007, including 326 retired workers (78.55%), mean age at onset of 54.21 years, significantly higher than the average age of onset of pneumoconiosis (47.88 years) in Sichuan Province from 1949 to 1998. The newly diagnosed In the case of pneumoconiosis, there are only 8 cases of building materials system, but there are 6 cases of pneumoconiosis in stage Ⅱ and Ⅲ, accounting for 75%, which is obviously higher than the 36.38% of the integrative diagnosis of newly diagnosed pneumoconiosis. Conclusion Occupational health monitoring of retired workers exposed to dust is as important as on-the-job workers and should be carried out on a regular basis according to law. Occupational health monitoring of building materials workers in Leshan City is seriously lacking and potential dust hazards are severe. Health supervision should be strengthened to protect the occupational health of workers , So custody down to the letter.
