Abstract
A 10-year follow-up of 327 civil servants with bronchitis (301 men and 26 women) is presented. A further 14 were lost sight of during the period, so that the follow-up was 96% complete. More than one half (54%) of the men died during the 10-year period, some 57% of the deaths being attributed to respiratory causes and a further 8% to carcinoma of the bronchus. Mortality from these diseases was higher than among the general population, but other causes of death showed the normal pattern. The degree of dyspnoea noted at the first interview gave a useful estimate of prognosis, the mild, moderate, and severe groups showing progressively higher death rates. Neither the length of history nor the age at onset of symptoms could be related to mortality. The proportion of smokers among the patients was greater than expected in the general population, and although this may have been a factor contributing to the excess mortality of the group as a whole, it was not possible to determine any effect of smoking within this study.
