吸烟是引起支气管慢性粘液分泌亢进、肺通气功能减退和肺癌的主要原因。但通气功能减退和(或)粘液分泌亢进与肺癌之间的关系尚无一致的看法.本文旨在观察通气功能减退和粘液分泌亢进能否预测肺癌的死亡率。方法在丹麦哥本哈根市随机抽样20岁以上居民19698人(其中40～69岁者50%),于1976～1978年间分别进行健康检查,总受检数14223人,受检率74%,其中资料完整者13946人,随访约10年。资料 Smoking is caused by chronic bronchial mucus hyperactivity, lung hypofunction and lung cancer the main reason. However, there is no consensus on the relationship between hypogonadism and hypersexpression of mucus and lung cancer.The purpose of this paper is to investigate whether hypogonadism and mucin hyperactivity can predict lung cancer mortality. Methods A total of 19698 residents (50% aged 40-69 years) over 20 years old were randomly sampled in Copenhagen, Denmark. Their health checkups were carried out from 1976 to 1978 respectively.
