Although the rise in ischaemic heart disease in England and Wales has been associated with increasing prosperity, mortality rates are highest in the least affluent areas. On division of the country into two hundred and twelve local authority areas a strong geographical relation was found between ischaemic heart disease mortality rates in 1968-78 and infant mortality in 1921-25. Of the twenty-four other common causes of death only bronchitis, stomach cancer, and rheumatic heart disease were similarly related to infant mortality. These diseases are associated with poor living conditions and mortality from them is declining. Ischaemic heart disease is strongly correlated with both neonatal and postneonatal mortality. It is suggested that poor nutrition in early life increases susceptibility to the effects of an affluent diet.

Overweight and obesity have been examined in 7735 middle-aged men in 24 British towns. Half the men exceeded the body mass index (BMI) range associated with minimum mortality (20-25 kg/m2). Social class differences in BMI were marked and obesity was more marked in manual workers. The association of reduced BMI with cigarette smoking and of increased BMI with stopping smoking was most clearly seen in manual workers. With increasing alcohol intake, BMI increased progressively, but the effect in the heaviest drinkers was probably diminished by concurrent heavy smoking. Mean BMI decreased with increasing levels of physical activity. There was considerable variation in the rate of obesity between the towns, from 11 to 28 per cent, determined to some extent by social class. Positive associations were observed between BMI and the presence of ischaemic heart disease, high blood pressure, gout, arthritis and gallbladder disease but not with diabetes mellitus. Peptic ulcer was inversely related to BMI and bronchitis showed a curvilinear relationship. For these men, overweight or obesity is virtually 'normal', and a considerable health education effort will be needed to produce a leaner, healthier society.

Men who do not drink are frequently used as a baseline against which the effects of alcohol consumption are measured. The characteristics of such men have been examined in a large-scale prospective study of cardiovascular disease involving 7735 middle-aged men drawn from general practices in 24 British towns. Non-drinkers include lifelong teetotallers and ex-drinkers, both long-term and recent. Long-term ex-drinkers have many characteristics likely to increase their morbidity and mortality; recent ex-drinkers have similar characteristics but to a less marked degree. Ex-drinkers are older than the other groups and include an increased proportion of unmarried men and men in manual occupations. They have the same high percentage of current cigarette smokers as moderate/heavy drinkers and a prevalence of hypertension and obesity similar to moderate/heavy drinkers and higher than lifelong teetotallers or occasional/light drinkers. Ex-drinkers have the highest percentage of men with multiple doctor-diagnosed disorders. In particular, they have the highest prevalence rates of angina and possible myocardial infarction on standardized questionnaire, of myocardial infarction on electrocardiogram and of recall of a doctor-diagnosis of ischaemic heart disease. They also have high prevalence rates of recall of high blood pressure, peptic ulcer, diabetes, gall bladder disease and bronchitis. They have the highest rates for regular medical treatment and the highest proportion of men who consider their health to be poor. It is abundantly clear that the general category of non-drinkers, which includes a large proportion of ex-drinkers, should not be used as a baseline against which to measure the effects of alcohol consumption. Overall, it would appear that the occasional/light drinking category (less than 15 drinks/week) provides a large and satisfactory baseline group for comparative purposes in the study of cardiovascular and other organic disorders.

In a random sample of 25,129 Swedish men who responded to a questionnaire on smoking habits in 1963 the cause specific mortality was followed through 1979. In the cohort, 32% smoked cigarettes, 27% a pipe, and 5% cigars. There were clear covariations (p less than 0.001) between the amount of tobacco smoked and the risk of death due to cancer of the oral cavity and larynx, oesophagus, liver, pancreas, lung, and bladder as well as due to bronchitis and emphysema, ischaemic heart disease, aortic aneurysm, and peptic ulcer. Pipe smokers showed similar risk levels to cigarette smokers. There was a close to linear increase in lung cancer risk in relation to the amount of tobacco smoked for cigarette, pipe, and cigar smokers, respectively. An increasing risk of ischaemic heart disease with amount smoked was seen among both cigarette and pipe smokers. A similar fraction of inhalers in Swedish cigarette and pipe smokers may explain the similarity in risks.

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.

Death certificates filed between 1960 and 1979 in Osaka, Japan were analyzed to study causes of death in diabetic patients. It was observed that diseases of the circulatory system increased continuously from 15.2% in 1960-1964 to 27.2% in 1975-1979. Cerebrovascular disease and disease of heart were the leading causes of death throughout the study period. The rate of increase was much faster for disease of heart than for cerebrovascular disease, and there was only a small difference between them as cause of death in diabetic patients at the end of the observation period. Malignant neoplasms, cirrhosis of the liver, and pneumonia and bronchitis increased, whereas tuberculosis decreased sharply according to age-adjusted mortality rate during the 20-year period. Analysis based on O/E ratios suggested higher risk of dying from ischemic heart disease, tuberculosis and cirrhosis of the liver in Japanese diabetics than in the general population in this country.

The frequencies of several factors, including major physical disease, in employed and unemployed men enrolled in the British Regional Heart Study (BRHS) have been compared. The BRHS is a prospective study of cardiovascular disease in middle-aged men selected at random from general practices in twenty-four towns. The unemployed group was subdivided into those who said they were unemployed because of ill-health and those who regarded their unemployment as not due to illness. The ill unemployed reported a much higher rate of doctor-diagnosed illnesses than the not-ill unemployed or the employed. The frequencies of bronchitis, obstructive lung disease, and ischaemic heart disease were higher in the unemployed than the employed, with the highest rates in the ill unemployed. The frequency of hypertension was the same in employed and unemployed men. Cigarette smoking and heavy drinking were apparently more common among the unemployed, but after adjustment for social class and town of residence only smoking was slightly higher among the unemployed. Use of tranquillisers was three to four times more common in the ill unemployed than in the not-ill unemployed or the employed. In this study, the unemployed had far more chronic physical illnesses than the employed, whether or not the employed men regarded themselves as ill. Studies of the health consequences of unemployment must allow for the pre-existing state of health, and evidence on the state of health cannot rely solely on self-reporting of illness.

A study was conducted to assess how lung cancer and other mortality trends among California physicians had been influenced by the high proportion who had given up smoking since 1950. Several sample surveys indicated that the proportion of California physicians who currently smoked cigarettes had declined dramatically from about 53% in 1950 to about 10% in 1980. During the same period the proportion of other American men who smoked cigarettes had declined only modestly, from about 53% to 38%. Using the 1950 American Medical Directory a cohort of 10 130 California male physicians was established and followed up for mortality till the end of 1979, during which time 5090 died. The information from follow up and death certification was exceptionally good. The standardised mortality ratio for lung cancer among California male physicians relative to American white men declined from 62 in 1950-9 to 30 in 1970-9. The corresponding decline in standardised mortality ratio was from 100 to 63 for other smoking related cancer, from 106 to 71 for ischaemic heart disease, and from 62 to 35 for bronchitis, emphysema, and asthma. The standardised mortality ratio remained relatively constant for other causes of death not strongly related to smoking. The overall ratio declined in all age groups at a rate of about 1% a year. The total death rate among all physicians converged towards the rate among non-smoking physicians. By the end of the study period physicians had a cancer rate and total death rate similar to or less than those among typical United States non-smokers. This "natural experiment" shows that lung cancer became relatively less common on substantial elimination of the primary causal factor, cigarette smoking. Other smoking related diseases also became relatively less common, though factors other than cigarette smoking may have contributed to this change.
