Recent trends in chronic obstructive pulmonary disease (COPD) mortality are described for a cohort of nearly 300,000 insured veterans who were followed for survival from 1954 through 1979. Death rates from COPD for the veterans by smoking status were compared with U.S. death rates for white males 55 to 84 yr of age over the same period. The main findings were that the veterans experienced sharp increases in COPD mortality over the 26-yr study period, much like the U.S. findings. However, the observed increases were not as great as those for the United States. The COPD rates for veterans who were cigarette smokers showed the same pattern as for all veterans. Some important differences by age were noted. Thus, for ages 60 to 64 and 65 to 69, the direction of the trend among veterans appeared to change from initial increases in the COPD death rate to later decreases while at the same time the three oldest age groups (70-74, 75-79, and 80-84) continued to experience increases in mortality over the whole period. These findings were similar to those for the United States. Several possible explanatory factors for these changes are discussed.
本文描述了近30万名参保退伍军人队列中慢性阻塞性肺疾病(COPD)死亡率的近期趋势,这些退伍军人于1954年至1979年期间接受了生存随访。将退伍军人按吸烟状况分类的COPD死亡率与同期美国55至84岁白人男性的死亡率进行了比较。主要发现是,在26年的研究期内,退伍军人的COPD死亡率急剧上升,这与美国的研究结果非常相似。然而,观察到的上升幅度不如美国。吸烟退伍军人的COPD死亡率与所有退伍军人的情况呈现相同模式。研究还发现了一些重要的年龄差异。因此,对于60至64岁和65至69岁的退伍军人,COPD死亡率的趋势方向似乎从最初的上升转变为后来的下降,而与此同时,三个年龄最大的组(70 - 74岁、75 - 79岁和80 - 84岁)在整个时期内的死亡率持续上升。这些发现与美国的情况相似。文中讨论了这些变化的几个可能解释因素。
