Recent shifts in lung cancer mortality in the United States are believed to be related to changing patterns of cigarette smoking among adults. From 1960-1977 the age-adjusted mortality rate for lung cancer increased by 85%. Increases in lung cancer mortality rates were much greater among females than males. The recent rapid increase in female lung cancer mortality appears to be the result of higher rates of cigarette smoking among women born between 1920 and 1940 compared to earlier generations. These women, who are now in their 40's, 50's, and 60's are now beginning to reach an age where lung cancer rates will be adversely affected. In contrast, peak smoking prevalence rates occurred among men who are now in their 60's and 70's. The proportion of men who smoke cigarettes has been declining steadily with successive generations born after 1930. Findings from this analysis suggest that recent shifts in lung cancer mortality in the United States can be largely explained by examining changes in the smoking habits of adults.
美国肺癌死亡率最近的变化被认为与成年人吸烟模式的改变有关。1960年至1977年期间，经年龄调整的肺癌死亡率上升了85%。女性肺癌死亡率的增幅远高于男性。近期女性肺癌死亡率的快速上升似乎是由于1920年至1940年出生的女性吸烟率高于前几代人。这些现在40多岁、50多岁和60多岁的女性，如今正开始步入肺癌发病率会受到不利影响的年龄阶段。相比之下，吸烟率的峰值出现在现在60多岁和70多岁的男性中。自1930年后出生的连续几代人中，吸烟男性的比例一直在稳步下降。该分析结果表明，通过研究成年人吸烟习惯的变化，美国肺癌死亡率最近的变化在很大程度上可以得到解释。
