In order to assess mortality patterns of Japanese physicians, the mortality during a 12 year period (July 1978-June 1990) among male members of the Chiba Medical Association was studied. The overall mortality among physicians was significantly lower than the general male population in Chiba prefecture (standardized mortality ratio [SMR] = 0.69). Physicians were found to have lower cause-specific mortality from cancer (SMR = 0.71), cerebrovascular disease (SMR = 0.42), pneumonia and bronchitis (SMR = 0.63), accidents (SMR = 0.37), and suicide (SMR = 0.29) than the general population, but to have higher mortality from senility (SMR = 1.75). When compared to the total working population and the professional and technical workers, all-cause mortality for physicians did not differ. Mortality from ischemic heart disease was significantly higher during 1979-1983, but was similar during 1984-1988. Analysis by specialty showed that during 1979-1983 internal medicine physicians had a lower mortality than surgeons, but this reversed during 1984-1988 with the former having a higher mortality than the latter. Over the whole period, no difference in mortality existed between internists and surgeons. A cohort of 2,502 male members that is being followed, showed that the mortality of physicians was lower than the general population. However, no significant difference between the internists and surgeons was observed in both overall and major cause-specific mortality.

A total of 3392 professional drivers in London were followed up in a prospective mortality study. There were significantly fewer deaths than expected from all causes (SMR 91, p less than 0.05), circulatory disease (SMR 75, p less than 0.05), and accidents (SMR 61, p less than 0.05). Lorry drivers showed excess deaths from stomach cancer (SMR 141, p less than 0.05), lung cancer (SMR 159, p less than 0.05), bronchitis, emphysema, and asthma (SMR 143, p less than 0.05), a pattern not evident among taxi drivers. Mortality from bladder cancers, leukaemia, and other lymphatic cancers were raised in taxi drivers, though the results did not achieve statistical significance. The importance of the findings is discussed.

A retrospective cohort study was conducted to examine mortality among 18,811 male farm owners and operators in New York State from 1973-1984. Farm Bureau membership lists were used to identify the study population, and vital status was determined through record linkage with death certificate and motor vehicle files. The comparison group consisted of the 1980 United States Census population of men who resided in the same towns as did the farmers. The results indicated that the study cohort experienced fewer than the expected numbers of deaths overall and for each major cause category except accidents. Specific causes with significant mortality deficits included cancer of the lung (standardized mortality ratio [SMR] = 47.0); diabetes mellitus (SMR = 57.5); ischemic heart disease (SMR = 65.3); bronchitis, emphysema, and asthma (SMR = 26.7); and cirrhosis of the liver (SMR = 29.7). The only specific cause with a significantly elevated mortality was accidents other than motor vehicle (SMR = 146.5). The investigation differs from previous research in method, setting, and population, but the pattern of findings is generally consistent with that of other studies.

To assess patterns of mortality in Japanese medical practitioners, we compared the mortality of male physicians in a Japanese prefecture with that of eight major working populations, the nonworking population, and the general population of all Japan and of the prefecture. Standardized mortality ratios were calculated. All-causes mortality in medical practitioners aged 25-64 years was significantly higher than that of administrative and managing workers (standardized mortality ratio [SMR] = 228); it was significantly lower than that of the nonworking population (SMR = 23). Physicians were found to have higher cause-specific mortality for pneumonia and bronchitis and for ischemic heart disease than the total working population. These findings suggest that the previously reported low mortality of physicians reflects principally their high socioeconomic status; within the professional class, the mortality of medical practitioners compares unfavorably with that of other persons.

A cohort of 3971 white miners in South Africa, born between 1 January 1916 and 31 December 1930 who were alive on 1 January 1970 and currently working in the East Rand-Central Rand-West Rand mining areas, was followed up for nine years, when the 3426 survivors were aged from 48 to 62. Fifteen (0.4%) had been lost to view and 530 had died (13.4% of the 3956 whose vital status was determined). Based on the occupational histories of a 30% sample of the cohort it was known that the vast majority were gold miners. An estimated 93% had worked more than 85% of their mining service in gold mines. Standardised mortality ratios were calculated as the ratios of the deaths observed in the cohort to those expected on the basis of concurrent mortality in the reference population--the total white male population in the Republic of South Africa. There was little sign of a "healthy worker effect"; of several possible reasons, one is that the white miner in South Africa had adopted certain unhealthy life styles, another is that the reference population was otherwise inappropriate. The SMR for all causes of death (117.6) was raised because of excess mortality due to the following causes: lung cancer (161.2), chronic respiratory diseases (165.6), and acute and chronic nephritis (381.0). A case-referent analysis was carried out on those miners in the cohort who had spent at least 85% of their service in gold mines. For lung cancer, smoking was the main contributory factor towards disease. For chronic respiratory diseases bronchitis, emphysema, asthma, pneumoconiosis, and pulmonary heart disease), smoking was also the main risk factor, but there was an association wih cumulative dust exposure. Raised blood pressure, smoking, and adiposity were associated with ischaemic heart disease as was the duration of service underground. Study of comprehensive medical histories in all 530 deaths, including necropsy in most cases, showed that none was directly due to pneumoconiosis or to tuberculosis.

A cohort study was done on 1396 deaths seen among 4352 Japanese male Zen priests during a follow up period from 1 January 1955 to 31 December 1978. Standardised mortality ratios were computed for major causes of death by comparing with the counterparts of the general Japanese male population. The SMR for all causes of death was 0.82 (p less than 0.001) and the SMR values for cerebrovascular diseases, pneumonia and bronchitis, peptic ulcer, liver cirrhosis, cancer of the respiratory organs, and cancer of the lung were all significantly smaller than unity. Taking regional mortality differences into account, a similar computation was made dividing the cohort into two subcohorts--that is, the priests living in eastern Japan and those in western Japan. Both subcohorts showed a highly significantly smaller SMR than unity for all causes of death. With the exception of only a few causes of death for which the observed number of deaths was small, they also showed such reduced SMRs for nearly all of the causes of death tested. A questionnaire survey on the current life style of active priests showed that they smoke less, eat less, meat and fish as they follow the more traditional Japanese dietary habits, and live in less polluted areas, but their drinking habits do not differ much from that of the average Japanese adult man. Possible reasons for their reduced mortality are discussed.
