对某铝业制造厂铝尘肺患病率的统计分析

Statistical analysis on prevalence of aluminum pneumoconiosis in an aluminum factory

目的了解某铝业制造厂铝尘肺及可疑铝尘肺的患病率,保障某铝业制造厂生产工人身体健康,做好职业病预防。方法通过连续5年职业健康监护,筛查接尘工人中的症状和体征阳性患者,通过血、尿常规及生化、心电图、肺功能和高千伏胸部X射线片,确诊铝尘肺患者。结果某铝业制造厂生产工人的症状、体征、血、尿常规及生化、心电图、肺功能和高千伏胸部X射线片等结果均有明显阳性率,部分患者尘肺病得到确诊;纵观5年体检,阳性率有一定的下降,各年份间比较,差异有统计学意义(P<0.05)。结论某铝业制造厂的铝尘肺控制具有一定成效。

Objective To investigate the prevalence of aluminum pneumoconiosis and suspected aluminum pneumoconiosis in an aluminum factory for ensuring the physical health of the production workers and doing the occupational disease prevention well.Methods The patients with symptoms and positive physical signs were screened out among the dust-exposed workers by continuous 5-year health surveilance and then performed the definite diagnosis of aluminum pneumoconiosis by blood routine,urine routine,blood biochemistry,ECG,pulmonary function test and high kV chest X-ray film.Finally,statistically analyze the results.Results The symptoms and physical signs,blood routine,urine routine,blood biochemistry,ECG,pulmonary function test and high kV chest X-ray film among the dust-exposed workers in this aluminum factory had significant positive rate.Partial patients were confirmed the diagnosis of aluminum pneumoconiosis.The positive rate had some decline during these 5-year physical examination.The yearly difference showed statistical significance（P0.05）.Conclusion The control of aluminum pneumoconiosis in this aluminum factory is effective.
