为了解青海省近年不同行业尘肺病病例年龄和工龄特点,对2012-2014年间我省诊断尘肺病例资料,按不同行业分组分析。结果显示,农民工尘肺病例年龄<50岁者147例,占85.9%,煤矿工人尘肺病病例年龄>50岁者170例,占64.9%;农民工工龄<5a者160例,占93.6%;煤矿工人工龄10~30a者181例,占69.1%;农民工平均晋级年限为7.5a,煤矿工人平均晋级年限为21.3a。提示,农民工尘肺病例比煤矿工人发病年龄小、接尘工龄与晋级时间短。 To understand the age and seniority of pneumoconiosis cases in different industries in Qinghai Province in recent years, the data of pneumoconiosis cases in our province during 2012-2014 were analyzed by different industries. The results showed that the number of migrant workers with pneumoconiosis was 147 (85.9%), the number of pneumoconiosis workers aged over 50 was 170 (64.9%), the number of migrant workers (<5a) was 160, accounting for 93.6% The number of workers aged 10-30 years was 181, accounting for 69.1%. The average age of migrant workers was 7.5 years and that of coal miners was 21.3 years. Tip, the incidence of pneumoconiosis migrant workers younger than the age of coal miners, dust service and promotion time is short.
