目的　探讨老年尘肺发病发展的流行病学特征。方法　对广东省7 885例老年尘肺患者进行流行病学调查。分老年尘肺组(60岁以上) 7 885例和对照组(60岁以下) 6 637例。结果　老年尘肺组发病年龄、发病工龄、晋期年限、存活和死亡患者病程均明显长于对照组(P＜0.01)。老年尘肺组病死率、并发肺结核率均显著低于对照组(P＜0.01)。结论　首次接尘年龄大、发病工龄长、病变进展慢、并发肺结核率低是广东老年尘肺流行病学的主要特征。做好预防和治愈并发肺结核，是保证尘肺患者“长寿”的主要措施之一。

Objective　To study the epidemiological features of the occurrence and the development of geriatric pneumoconiosis (GP). Methods　7 885 cases among GP in Guangdong had been studied. GP group (age＞60 years) was consisted of 7 885 cases and control group (age＜60 years) was 6 637 cases. Results　The results showed that the age of patient suffering from pneumoconiosis, length from dust exposure to the pneumoconiosis onset, the stage promoting interval and course of disease of both survival and death in GP were significantly longer than those of control group (P＜0.01). The mortality rate and the prevalence of pulmonary tuberculosis complication in the GP were significantly lower than those in control group (P＜0.01).Conclusion　It suggested that the older the workers firstly exposed to dust, the longer the pneumoconiosis onset, the slower the pneumoconiosis development and fewer the pulmonary tuberculosis complication appeared to be the main features of geriatric pneumoconiosis in Guangdong epidemiologically. The effectivenss of the prevention and cure of pneumoconiosis complicated by pulmonary tuberculosis might be regarded as one of the main effects on the longevity of patients with pneumoconiosis.
