Ten-year mortality rates for lung cancer and coronary heart disease have been related to cigarette smoking habits in 17 475 male civil servants aged 40-64 and in sample of 8089 male British residents aged 35-69. Both diseases were more frequent in smokers. Lung cancer rates were higher overall for "non-inhalers", particularly in heavy smokers. Tar yield correlated with the risk of lung cancer in non-inhalers but less so in inhalers. Conversely, coronary deaths were more common among inhalers, and the effect of tar/nicotine yield (such as it was) was confined to inhalers. It appears that there are subtle interactions between the amount smoked, the tar/nicotine yield of the cigarette, and the style of smoking. Thus the effects of a change in cigarette characteristics are hard to predict, and they may be different for respiratory and cardiovascular disease.
在17475名年龄在40至64岁的男性公务员以及8089名年龄在35至69岁的英国男性居民样本中,肺癌和冠心病的十年死亡率与吸烟习惯有关。这两种疾病在吸烟者中更为常见。总体而言,“非吸入式吸烟者”的肺癌发病率更高,尤其是重度吸烟者。焦油含量与非吸入式吸烟者患肺癌的风险相关,但与吸入式吸烟者的相关性较小。相反,冠心病死亡在吸入式吸烟者中更为常见,焦油/尼古丁含量(如有的话)的影响仅限于吸入式吸烟者。看来,吸烟量、香烟的焦油/尼古丁含量和吸烟方式之间存在微妙的相互作用。因此,香烟特性变化的影响很难预测,而且对呼吸道疾病和心血管疾病的影响可能不同。
