本文应用寿命表相关回归法对我市3570例初次诊断Ⅰ期尘肺病人死亡趋势及肺结核死因对尘肺病人生存年限影响分析表明:Ⅰ期尘肺病程累积死亡机率变化趋势为(?)X=0.1010x+3.0973(r=0.9947)。从理论上推算Ⅰ期尘肺病人预期生存年限为11.7年。在去除肺结核死因后,尘肺病人期望生存年限为12.3年,平均延长0.6年,其累积死亡机率趋势为(?)_x~(-i)=0.0937x+3.0756(r=0.9943)。提示我们应重视尘肺病人的防痨抗痨工作。
In this paper, life-table regression analysis of 3570 cases of our city for the first time diagnosis of pneumoconiosis pneumoconiosis mortality and pulmonary tuberculosis death causes of pneumoconiosis patients life span analysis showed that: stage pneumoconiosis cumulative mortality probability trend (?) X = 0.1010x + 3.0973 (r = 0.9947). It is estimated theoretically that the expected life span of stage I pneumoconiosis patients is 11.7 years. After removing the cause of death from pulmonary tuberculosis, the expected life span of patients with pneumoconiosis was 12.3 years, with an average extension of 0.6 years. The cumulative probability of death from pneumoconiosis was (?) _ X ~ (-i) = 0.0937x + 3.0756 (r = 0.9943). Tip we should pay attention to pneumoconiosis anti-tuberculosis work.
