摘要
通过对1077名井下矿工队列的28年回顾性定群研究,发现吸烟组矽肺发病率为13.02%,非吸烟组为6.85%。吸烟组矽肺的标化发病率比为171.43(95%CI=144.69～203.97)。以接尘工龄作时间变量,用Weibull回归模型分析累积接尘量和吸烟对矽肺的影响。结果表明在平衡了接尘工龄后,累积接尘量和吸烟对矽肺发病的影响有显著性意义,说明了有吸烟习惯的接尘工人发生矽肺的危险度比不吸烟者大。因此,在预防矽肺的措施上,应强调控制吸烟的重要性。
A retrospective cohort study of 1077 underground miners showed thatmorbidity of silicosis was 13.02/1000 in smokers,and 6.85/1000 innon-smokers.The standardized morbidity ratio for silicosis of smokers was171(95% CI=145-204).Results of Weibull regression model analysisshowed that cumulative dust dose and smoking significantly increased risk forsilicosis when using the years of exposure to dust as time variable.So the im-portance of controlling smoking should be stressed for the prevention ofsilicosis.
