Male volunteers for mass radiography examination aged 40 or more were questioned about their sputum production, smoking habits, and, when applicable, their method of smoking cigarettes.Of 5,438 cigarette smokers 1,051 (19%) claimed that when smoking a cigarette they usually extinguished it at some stage and later relit it to smoke again. Anyone who admitted to producing sputum from his chest on most days of the year or on most days for a minimum of three months of the year for at least the last two years was classed, in the absence of other causative disease, as a chronic bronchitic. Such chronic bronchitics totalled 1,864 (34%).The rate of chronic bronchitis among relighters (39.7%) was higher than the rate (32.9%) among the remaining cigarette smokers. The difference was of high statistical significance (P<0.001), and the same pattern was maintained when age and consumption were standardized. After allowing for a trend towards lower social class and a preference for plain as opposed to filter cigarettes the rate of chronic bronchitis among relighters was about 15% greater than that of the remaining cigarette smokers.
对40岁及以上参加大规模X线摄影检查的男性志愿者询问了咳痰情况、吸烟习惯，以及（如适用）吸烟方式。在5438名吸烟者中，1051人（19%）称吸烟时通常会在某个阶段将烟熄灭，之后再重新点燃继续吸。在过去两年中，任何承认在一年中的大多数日子或至少连续三个月中的大多数日子从胸部咳出痰液的人，在无其他致病疾病的情况下，被归类为慢性支气管炎患者。这类慢性支气管炎患者共有1864人（34%）。重新吸烟者的慢性支气管炎发病率（39.7%）高于其余吸烟者的发病率（32.9%）。差异具有高度统计学意义（P<0.001），在对年龄和吸烟量进行标准化后，同样的模式依然存在。在考虑到社会阶层较低的趋势以及对普通香烟而非过滤嘴香烟的偏好后，重新吸烟者的慢性支气管炎发病率比其余吸烟者高出约15%。
