Smoking habits among Norwegian doctors 1974.

In the spring of 1974 a representative sample (N = 1200) of all doctors in Norway (6 000) received a mailed questionnaire regarding past and present smoking habits. Close to 95% responded. Among late responders there was a disproportionately high number of smokers. As compared with the general population, both male and female doctors constitute a small proportion of daily smokers and a large proportion of exsmokers. The greatest contrasts are observed in the younger age groups. The percentage of daily smokers in this crossectional study on the medical profession is approximately 50% lower than that found in the 1952--53 study on Norwegian doctors. There is also a shift away from cigarette smoking toward the use of pipe and cigars, which is not found in the general population. Answers to questions regarding reasons for quitting as well as certain attitudinal indicators show that the doctors' reduction in smoking is related to their professional involvement and high level of knowledge concerning the health consequences of smoking.

Some evidence of the efficacy of mass BCG vaccination.

To assess the efficacy of mass BCG programmes the authors have made a comparative analysis of age-specific trends in the incidence of active tuberculosis in the three Scandinavian countries, where mass vaccination of specific age-groups has been carried out since the late 1940s, and two states of the USA (upstate New York and Ohio), where mass BCG campaigns have never been conducted.In the three Scandinavian countries a markedly more favourable incidence trend was observed in the age-groups following the first inoculation-as compared with other age-groups in the same country and with corresponding age-groups in the other countries where a different BCG programme, or no programme at all, has been applied. The authors consider that these observed differences in incidence trends reflect the influence of BCG vaccination and, on this assumption, have attempted to estimate the primary effect of the BCG programmes quantitatively, in terms of hypothetical "gained and lost cases" in the various age-groups. They stress, however, that the significance of these gained and lost cases must be evaluated from an epidemiological viewpoint and that the relevant epidemiological factors must be taken into account in the planning of BCG programmes.
